How to make a pipe bender with your own hands - main points during development

To make a pipe bender for a profile pipe with your own hands, you will need drawings and some equipment. Let's look at how to assemble different options for such devices.

Crossbow pipe bender for round pipe

The most popular are mechanical, hydraulic and electric crossbow-type pipe benders. They use a special nozzle, the diameter of which varies depending on the size of the communication. It is designed for cold processing of round metal products.

As a basis for developing your own crossbow pipe bender, you can use option 4 from the “drawings” section of this article.

Hydraulic pipe bender

Hydraulic pipe benders are used to bend a pipe without filling it, i.e. nothing is inserted into the fitting hole. They are very convenient if you need to deform a bend with a square or rectangular cross-section, or without holes. The disadvantages include the fact that due to such an effect the internal radius changes slightly, which is not always acceptable for processing pipes for drainage or sewerage.

Wood pipe bender

The simplest option for thin-walled aluminum pipe is a template bender. He is simple design from a specific template (made according to the required bend angle) and clamping devices.

Making a template pipe bender with your own hands from wood - step-by-step instructions:

1. Cut from a board of suitable thickness definite shape. Depending on the required degree indicator, its angle is measured;
2. Afterwards the form is permanently installed on the future rolling table. It is most convenient to mount it with screws, since then the installation can be moved to another place;
3. This pipe bender is a lever bender, so you also need to make a handle, which will do the main work;
4. The stop is installed at a distance from the template, which corresponds to the diameter of the element being bent, and is secured with screws. He must be motionless;
5. The process of working on it is as follows: the product is inserted into the hole between the template and the stop and bent by hand.

This is a simple option, but not ideal, since you will have to make a new template each time. In addition, the angle obtained by such bending will not be entirely accurate.

Making a pipe bender from a jack

The pipe bender design made from a jack is more practical, because you can choose different angles deformation. To construct such a device, you will need a winch, a hydraulic jack up to 5 tons, an engine and gearbox, a plate, and a jumper. This device is semi-automatic, therefore more convenient for domestic use.

First of all, you need to select the base for the frame on which the machine will be installed. You can take simple corners, but with a cross-section of at least 8 mm, so that they can withstand the weight of the product and other devices. The base must be regular table, the jack is attached to it using bolted connections. Then you need to install it on the table according to the drawing or instructions. Instead, you can even use small sections from other pipes.

To bend large pipes, you will need a more serious installation, it is called bending. The bend is made from steel profile pipe large diameter, a special metal template or other frame the desired shape. This homemade pipe bender works on a similar principle to the template one, except that you need to use your own physical strength. The jack is connected to the gearbox and motor, the product is installed between the frames and the device is connected to the network. Due to the pressure provided by the jack, the pipe is bent according to the pattern.

Roller pipe bender - step-by-step photo instructions

Similarly, you can assemble a three-roll roller tool, only in this case you need to install several profiles at once, acting as templates. This do-it-yourself pipe bender design may be needed when making a complex structure, where you need to bend the product in several places at once.

At all roller pipe benders, I think, are the easiest to make. Below you can see a complete step-by-step photo instruction on how to create a roller pipe bender with your own hands.

You will need:

• Electric welding;
• Two 1045 steel rollers (pre-turned): the largest is 100 mm in diameter and the smallest is 60 mm in diameter, both 35 mm thick and with a cavity radius of 12.5 mm (half an inch).
• A tube with a diameter of 1 “1/4 (it will serve as a lever) with a thick wall (the one in the photo is 3 mm) and a length of 1.5 meters.
• Steel strips 4 or 5 mm thick (for the base and for supporting the rollers).
• One 3/4" bolt (for the large roller axle) and another 1/2" bolt (for the smaller roller axle) to screw into the base with an approximate thickness of 50 mm.
• Other hand tools, saws, vices, hammers, calipers, etc.

It should be noted that this machine is designed for bending pipes with a diameter of 1 inch and not for any other diameters! If a different diameter is needed, then other pulleys with the corresponding groove can be machined.

• 
  
• 
  

  Components (parts) that we will need in our work

• 
  

  These are the steel rollers I have. The groove must be machined very clearly, since there must be a hole between them to accurately position the tube of the above-mentioned diameter.

• 
  

  Step 1: Now, here I am starting to assemble the structure. First I soldered a U-shaped profile to which the steel cogs are attached.

• 
  

  Step 2: Then I weld a 3/4" bolt to the base plate (I first sawed off the head of the bolt and made a corresponding hole in the plate so that I could weld it on the back)

• 
  

  Step 3: Using a welding machine, weld the bolt to the plate

• 
  

  Step 4. Next I use a 1/2″ bolt to act as the axle for the small roller (I sawed off the head of that one too).

• 
  
• 
  

  Step 6: We weld the stop for the pipe and two control corners (because there will be a lot of pressure in this place)

• 
  

  Step 6.1 (continuation of work)

• 
  

  Step 6.2 Already welded corners and metal plate to the board (result)

• 
  

A pipe bender is a very useful tool on the farm if you are used to doing everything yourself. Sheds, greenhouses and canopies are made from bent profile pipes, and they add water pipes desired bend. Using this tool it will not be difficult to make all kinds of products that have a variable radius. You can save on buying a tool and make it yourself according to drawings and photographs. The video master class will show all the intricacies of the process.

Types and models of pipe benders

On construction market You can purchase different modifications of professional pipe benders. For bending small-diameter pipes, a hand-powered tool is suitable; Large diameter pipes are bent with a tool equipped with a hydraulic drive. Industrial units are either stationary or portable. The tool is easy to use and connects to the mains. Pipe benders are classified according to the bending method:

• Crossbow-type pipe benders use a template of the required diameter as a bending unit;

• a manual drive bends pipes using springs;
• Segmental pipe benders bend pipes along a segment. They are most often used by plumbers;

• mandrel mechanisms are designed for bending thin-walled pipes to a small radius.

Advice. In special reference books you can find tables with permissible bending radius values ​​depending on the thickness and diameter of the pipe. Violation of the radius will create zones with increased metal stress, which will significantly reduce the quality and strength of the pipe.

The simplest pipe bender from a template

This mechanism is suitable for small diameter pipes. The template is made from boards that are thicker than the diameter of the pipe. The edge of the template is cut at an angle so that the pipe does not slip out. The boards are fastened together and fixed on the table surface. A stop is attached at a certain distance from the template. The pipe is inserted between the stop and the template and bent. The pipe cannot be bent from the center of the template - it will break. And if it doesn’t break, then appearance will not stand up to any criticism.

In a similar way, a pipe bender is made from a concrete slab and strong metal pins. Holes are drilled in the concrete and pins are driven in at a distance of no more than 5 cm, and stop pins are driven in at the edges. To fix a curved pipe, a jumper can be welded to its ends, which is then dismantled.

A similar template can be made from a sheet of plywood and hooks. By changing the location of the hooks, you can change the bending radius of the workpiece.

Roller manual pipe bender

In the manufacture of such a mechanism, the main difficulty lies in the selection of rollers and the desired template. The bend will not be of high quality if the rollers do not wrap around the pipe. To bend flexible pipes, rollers can be cut from wooden blanks hard rocks. Rollers can be made on lathe or using a jigsaw.

Wooden circles are cut out at the required slope, then assembled into one piece and sanded with sandpaper. To give strength to wooden parts, they are reinforced with metal plates. To bend pipes over a large radius, you will need a pipe bender with three rollers.

Pipe bending machine

A manual rolling machine will be a good help in a home craftsman’s workshop. To make it, you will need materials that can be bought at a reasonable price at metal collection points.

The distance between the shafts matters. The farther the shafts are located, the less force the operator will need to apply to push the pipe; the minimum radius value increases and the distance of the pipe section that will not be processed increases; accordingly, the stroke of the pressure shaft will be longer. Therefore, at the drawing design stage, it is necessary to calculate several options for the position of the side shafts.

If rollers are used instead of shafts, stops (steel angles) must be placed on the sides, which will hold the pipe in a strictly vertical position and perpendicular to the axis of the rollers. Otherwise, the profile pipe will bend into a spiral. After final assembly, the device can be painted for aesthetic pleasure.

The above device can be improved if desired. Add a motor with a gearbox to the tool, which will drive the shaft by rotating the chain drive. Installing a jack instead of the upper shaft will allow you to bend pipes of different diameters. The jack regulates the pressure and sets the height. This upgrade will allow you to bend pipes on an industrial scale for a small enterprise, under all kinds of radii.

It is convenient to work on such a machine with a partner: one person turns the winch, and the second pulls the pipe. The pipe blank is placed on rollers and pressed with a jack. The winch pulls the pipe along the shafts, then the jack force is added and the workpiece is driven through again. The cycle is repeated until the pipe acquires the desired bend.

Advice. When bending a profile pipe, sand poured inside the profile will protect it from destructive deformations.
The device, once made independently, will last a very long time and will be in no way inferior in quality to purchased equipment. If you need a pipe bender for one-time use, then it is more advisable to rent the device.

How to make a pipe bender with your own hands: photo

There are many models of industrial pipe benders on the construction markets, but buying professional tool It hardly makes sense to bend two or three pipes. But making this simple tool with your own hands and using it in the household is within the capabilities of every person who has certain technical skills.

Application of pipe benders

Pipes were and are one of the most popular building materials, which are used both in households and in industry and construction. In addition to being used in the installation of water and gas pipelines, pipes are also used for the manufacture of fences, greenhouse structures, gazebos, canopies, garden furniture etc. Thus, having a pipe bender in the household will never be superfluous.

Often for making various designs from pipes it is necessary to bend profile pipes along the radius. For these purposes, a pipe bender is used, which allows bending pipes to an angle of 180 degrees. Pipe benders allow you to easily and accurately change the configuration of pipes made of various materials - aluminum, metal-plastic, stainless steel. The bend is made according to the required shape and dimensions.

Types and models of pipe benders

The industry produces various types of professional pipe benders. To bend pipes of small diameter, hand-powered tools are usually used, but pipes with a diameter of up to three inches are bent using pipe benders equipped with a hydraulic drive.

This type of tool is designed for large-scale work. Industrial pipe benders can be made in both stationary and mobile versions. The most convenient tool is one that connects to the mains.

Electromechanical pipe benders provide the most exact angle and bending radius. In this case, changing the shape of the pipes does not entail any deformation of the internal profile.

Pipe benders are also divided according to the bending method:

• in crossbow pipe benders, a shape of a certain diameter is used as a bending element;
• manual spring tool designed for bending metal-plastic pipes using special springs;
• in segmental pipe benders, bending is carried out by stretching the pipe around the segment; mandrel tools bend thin-walled pipes to a small radius using steel, plastic and brass mandrels.

When bending a pipe, the permissible bending radii for pipes should be taken into account various diameters and different wall thickness parameters. Allowable bending radii for products various characteristics presented in special reference books. If the radius is violated, the quality of the bend can be significantly reduced.

Let's start production

Despite the apparent simplicity of the process, bending pipes requires a rather serious approach, since with an incorrectly selected tool, various defects and deformations are possible, leading to a decrease in the throughput of pipes and a decrease in their strength characteristics.

Therefore, the selection of tools is carried out taking into account the compatibility of the characteristics of the pipe and the operating principle of the tool.

Pipes made of different materials, having different diameters and different wall thicknesses have a certain minimum bending radius. The following table is used to determine it:

Of course, it is possible to bend pipes with a smaller radius, but it should be taken into account that this will reduce the quality of their bending.

Now let's talk about making pipe benders ourselves and consider several designs of such tools.

The easiest way to bend a pipe is to use a special template. It should be noted that this method allows you to bend not only aluminum but also steel pipes.

To make the template we need wooden boards thickness slightly exceeding the diameter of the pipe being bent. To ensure that the pipe does not slip out of the template during operation, the boards are cut with a certain slope.

The boards fastened together must be fixed on a table or other convenient base. In addition to the template, you should also attach a stop here at a certain distance to hold the pipe being bent. The simplest model pipe bender is ready.

The end of the bendable pipe is inserted into the space between the fixed template and the stop. Taking the pipe by the opposite end, you need to bend the product with smooth movements. To facilitate the process, you can use a lever by inserting a strong reinforcing rod into the pipe or put a larger diameter pipe on the product to be bent.

Trying to bend the pipe in the center of the template should be avoided, as this not only requires significant force, but may also cause the pipe to break.

A similar template can also be made from metal hooks attached to a sheet of plywood along the corresponding bend line. The advantage of this design is the ability to adjust the bending line by rearranging the hooks.

The simplest pipe benders allow you to bend not only thin-walled flexible pipes, but also thick-walled products. To do this, use a hand winch.

Using this design, even powerful profile pipes can be bent. However, for these purposes, when cutting out a wooden template, you should not make a bevel, and the pipe must be secured with several stops at once.

In various workshops you can often find pipe benders with a similar design:

You can make it yourself. In the process of manufacturing such a pipe bender, the most problematic is the selection or production of the necessary templates and rollers, since the quality of the bend depends on the girth of the pipe.

If the tool is designed to work with flexible pipes, steel rollers and templates can be replaced with similar parts made from hardwood.

The rollers can be turned on a lathe. Also, the roller can be cut with a jigsaw. To do this, circles are cut out of hard plywood. different diameters tilted in the required direction, which are then fastened into a single piece. Finally, the roller should be sanded. To give greater strength to the product, it should be reinforced with metal plates.

To obtain a large bending radius, it is optimal to use rolling pipe benders. These tools, like those described above, are not distinguished by their design complexity.
In general, the level of complexity of the design of rolling pipe benders largely depends on the material of the pipes being bent.

If the tool is needed to work with flexible pipes, its working surfaces can be made of wood. Since wooden parts are quite simple to manufacture and do not require large expenses, they can be easily replaced when worn out.

If wooden parts prove to be ineffective, they can be replaced with metal ones. Let's look at several designs of homemade rolling pipe benders.

As you can see, this tool is made mainly from wooden parts. The rollers in this model are made of polyurethane, however, they can also be made of wood. T

Bearings can also be used as rollers. However, in this case, you will need to jam the pressure bearing so that it does not rotate.

Its technical characteristics depend on the distance between the rollers of a pipe bender. The greater the distance between the rollers, the less effort will be required for bending and running the pipe. However, in this case, a minimum bending radius is ensured, and a significant section of the pipe is not subject to bending at all.

In order to produce a more versatile tool, the possibility of installing side rollers in different positions should be provided at the design stage.
It is necessary to fasten steel clamps on the sides to hold the pipe in a certain position perpendicular to the axes of the rollers. Otherwise, the pipe will begin to bend in a spiral.

The pressure roller of the pipe bender should be tightened from below using a metal strip with a thread of the required diameter cut in the center.

By smoothly tightening the pressure roller of the device, the bent pipe is rolled through the pipe bender. When rolling, for every half turn of the fixing metal strip, a pipe is run through.

When bending a small radius, you will need to make from 50 to 100 runs. To ensure that the bending circle does not undergo deformation, it is necessary to roll the pipe at the same speed. If there is a weld on the surface of the pipe, it is necessary to ensure that the seam is always on one side during rolling.

Homemade pipe bender for profile pipe

Spring is coming, rooks are coming, and the greenhouse has been unfinished for many years now). From the very beginning I decided to make a normal greenhouse from a normal profile. To do this you need to bend the frame. You can, of course, look for where it is bent or even buy a ready-made one, but we are not looking for easy ways. We will bend it ourselves, and for this we need to make a pipe bender. It will come in handy more than once on the farm...

So, having rummaged through the search for drawings or diagrams for making a pipe bender with my own hands, I collected a small collection of photos. So let's start this manufacturing process with drawings and photographs.

The pipe bender itself:

A little manufacturing process:

Well, when we already have an idea of ​​the design, the drawings themselves:

The most important thing is to grind the rollers and races for the bearings. We select the shaft sizes based on our bearings and sprockets. You can avoid sprockets altogether by making the drive from a single roller, but according to reviews, this can cause the structure to slip.

You can also replace the clamping screw with a jack. In any case, the main shafts.

Well, let's start selecting materials and adjusting drawings? In the meantime, you can look at an even more advanced option. The shafts are machined to a couple of diameters round pipes and under a regular profile pipe.

To begin with, I bought bearings. I didn’t buy simple ones, but bought self-centering ones with supports that cost a ruble more. Since a “premium class” profile bender will be made, the gears and chain for it must be premium). In my case, Mercedes ones.

The turner's task was formulated on a piece of wallpaper and he successfully completed the task.

Well, the first fitting

The gears will be secured through a key. You also need to drill holes in the rings and cut threads to secure them.

I drill holes and make grooves for the key to attach the gear.

I drill holes in the restrictive rings and cut threads for clamping bolts. I sawed off a piece of channel to mount the pressure shaft. One shelf was cut off so as not to interfere with the installation of the jack. Holes are drilled and threaded for mounting the bearings.

Now you can move on to welding work. I lay out the parts on the “welding table”. I assemble the structure and weld the legs.

We fasten the pressure shaft. We touch it and weld the nuts for the springs.

I hang the platform on springs. By the way, the upper stop is bolted on, just in case you suddenly have to remove the pressure shaft.

I'm making a chain tensioner. Use a magnetic corner as a holder. Great stuff!

I screw the sprockets on, not forgetting to insert the dowels. The dowels were made by cutting with an engraver.
I tighten the tensioner.

The next part is the handle for rotation. Don't forget to make a handle with a rotating tube so as not to rub calluses. And we install the jack, weld a couple of bolts and fix it on the site.

Result

It's time for bench testing! What can I say about the quality of the bend... the bend itself turned out just wonderful. There is a slight crease at the extreme points. There is no way without it. But thanks to the collar on the central shaft, there is no jam along the arc.

In principle, I am more than satisfied with the result. The machine turned out just right. It turns easily, bends well. All that's left is to give it a little presentation... paint is used.

A pipe bender for a profile pipe is a tool needed for certain situations, and there is a steady demand for it in the market. The pipe bender can be used in a variety of areas where there is a need to give a pipe a specific shape. Of course, such a tool can be purchased, but if you want to save money, you can make it yourself.

To assemble a pipe bender, you need knowledge about its structure, operating principle and characteristic features. This work will also require the appropriate tools and instructions. How to make a pipe bender for a professional pipe with your own hands will be discussed in this article.

Main characteristics of a pipe bender

Structurally, a profile pipe bender is a specific machine for rolling profile pipes, allowing you to bend pipes with various options profile sections.

Good pipe benders for profile pipes allow you to solve several problems, including:

• The ability to bend the pipe at the required angle, the value of which can reach 180 degrees;
• Ability to work with pipes in a fairly wide range of diameters - from 5 to 1220 mm;
• Possibility of processing pipes made of different materials (if necessary, you can bend both metal and plastic products).

Basically, the need for a pipe bender to process polymer pipes is absent - such material can be bent in other ways. But when processing metal products you cannot do without professional equipment.

Of course, you can always purchase a ready-made tool or rent it, but these solutions cannot be called the best. Renting specialized equipment is usually expensive, and purchasing it is even more expensive. In addition, you need to understand that buying a pipe bender for a one-time job will not be the best profitable option. To avoid extra costs, many make pipes bending machines with your own hands.

Application of pipe benders

However, the main scope of application of such equipment is the laying of various pipelines and installation of buildings, in which profile pipes are often used as fittings. Regardless of the shape and type of raw material used to produce pipes, they can still only be bent using special machines - otherwise positive result will not be possible to achieve.

The scope of application greatly influences the bending parameters of pipes. The fact is that the material can have different sizes and raw materials, and the requirements for bending are different. To process pipes properly, you need to use equipment of the appropriate power and capabilities. In addition, an important aspect is the drive of the device, which can be manual, electric or hydraulic.

Types of pipe benders for profile pipes

The main factor by which pipe benders are classified is the device drive, depending on which three categories of devices are distinguished:

1. Hydraulic.
2. Electrical.
3. Manual.

There are many differences between these devices - different configurations, operating principles and equipment costs. It is worth considering them in more detail to understand these differences.

Electrically driven devices are among the most expensive, but the high cost is fully justified (more details: ""). The technical characteristics of such devices, including high power, precise adjustment of the pipe bending angle and convenient control, are at the very top high level. As a rule, professional installers use this tool.

Hydraulic pipe benders, although somewhat inferior in cost to electrical devices, also cannot be classified as budget ones. Such devices are usually used in situations where the power of a manual pipe bender is not enough.

Hydraulic devices have many advantages:

1. High pace of work. Thanks to its high and stable power, a hydraulic pipe bender is able to process pipes much faster than manual devices.
2. High processing precision. Unlike manual devices, hydraulic devices allow you to bend the pipe with an accuracy of 1 degree.
3. Ease of operation and maintenance. This type of device is very easy to use and does not require special maintenance. Even if the device fails, you can repair it yourself. In addition, the work will not require a lot of effort, which is simply necessary when processing with manual pipe benders.
4. Light weight and compact. If necessary, any hydraulic pipe bender can be moved from place to place without much difficulty.
5. Versatility. Unlike hand-held devices Having a number of unpleasant limitations, hydraulic pipe benders allow you to work even with steel products of medium diameter.

In addition to the types of pipe benders already described above, there are also manual devices that are characterized by the lowest cost and simplicity of design. A manually operated pipe bender for profile pipes is quite mobile and easy to use. It is also worth noting that if they want to make a pipe bender with their own hands, most users choose this option.

However, you have to pay for the low cost with other qualities. Firstly, manual devices are poorly suited for large volumes of work due to the difficulty of using the device for a long time. Secondly, the principle of operation of such devices is simple, but it is difficult to work with them - you have to put in too much effort to bend the pipe well. Thirdly, manual pipe benders are only suitable for processing plastic and aluminum pipes. At great desire Steel products can also be processed, but only if their diameter is small.

In addition to classification by type of drive, pipe benders are divided according to the method of bending the pipe, depending on which three types of devices are distinguished:

• Crossbow, in which the pipe is bent due to a special shape;
• Spring manual, bending the pipe due to the force generated by the springs;
• Segmental, having a design from dense material with mandrels installed, around which the pipe is bent.

DIY manual pipe bender

Many owners are concerned about the question of how to make a manual pipe bender for a profile pipe with their own hands. This question is quite relevant - purchasing ready-made tools is expensive, and the quality of some of them leaves much to be desired. No wonder that various schemes pipe benders are proving popular and in demand.

To create a simple manual pipe bender you only need three components:

• Concrete slab;
• Several metal pins;
• Hammer.

Assembling all the parts into one whole is not particularly difficult. First you need to divide the slab into squares with a side of 4 cm or 5 cm. When these squares are marked, deep holes are drilled in their corners using a hammer drill, into which pins are then installed. It is best to have drawings of homemade pipe benders for profile pipes with you so that you can constantly refer to them.

The operating principle of this primitive design is quite simple: the pipe is placed in the space between the pins and bends due to physical effort. Such a manual bending machine for profile pipes is not very convenient to use and does not allow achieving high accuracy of the bending angle, but for a small amount of work in domestic conditions its capabilities are enough.

Alternative designs for manual pipe benders

The simple pipe bender described above is not suitable for all situations. If higher performance is needed, you will have to look for a more complex design. Enough effective option A homemade pipe bender is a design whose main working element is a jack. To assemble manual pipe benders for a profile pipe with your own hands, you will need a hydraulic jack that can withstand a load of up to 5 tons, a strong base and pins.

There is one more interesting option– a pipe bender with a chain drive, which is started using a handle. The drawing of a pipe bender of this type includes a metal base in the shape of the letter P, a clamp, three rollers, a winch and a chain. The parts are connected by welding.

The assembly algorithm for such a tool is as follows:

• First of all, a U-shaped part is attached to the base;
• Two rollers are attached to both sides of the part, and the third is installed so that they all form an isosceles triangle;
• A chain with a connected winch is wound onto the rollers.

Homemade hydraulic pipe bender

Hydraulic pipe benders have many advantages over manual devices, but all of them are determined by the complexity of the design. Because the hydraulic equipment is complicated, then assembling it yourself will be much more hassle. To assemble such a pipe bender you will need a strong base, U-shaped metal part, shaft, pulley, chain and hydraulic rod.

Making a homemade hydraulic pipe bender looks like this:

• The first step is to install the shaft on the base;
• A pulley is attached to one end of the shaft, and a chain is attached to the second, after which the next shaft can be installed and connected to the first by a chain;
• In the lower part of the structure you need to cut an opening for the movement of the rod;
• Next, the third roller is installed, which is the main element that bends the pipes;
• The third roller shaft is installed in the grooves of the base.

Homemade rolling machine for bending pipes

The set of materials required for work looks like this:

• Concrete base;
• Wheels;
• Winch;
• Engine;
• Metal jumper;
• Jack;
• Gearbox.

It is best to assemble a pipe bender for a profile with your own hands in several stages to simplify the work:

1. The first step is to prepare the base. It will require metal elements and a welding machine. Four supports are attached to the base, after which holes can be drilled in the structure, allowing you to adjust the bending radius of the profile pipe.
2. Next, a jack is installed using bolts and plastic, after which you can attach a winch with rollers, both engines and a jumper.
3. Last step– installation of a “fungus”, which is essentially an ordinary pipe curved at a right angle. The “fungus” is attached to the upper part of the machine body.

A pipe bending machine for a profile pipe assembled according to this scheme has a complex design, but the difficulties of assembly in the future will more than pay off due to efficient and simple operation.

Conclusion

There are a variety of options for pipe benders for profile pipes. If we're talking about about purchasing such a device, then it all comes down to choosing the necessary technical characteristics, and when self-assembly It will also require a lot of effort aimed at creating the most efficient and reliable design.

Bending profile pipes is a fairly common procedure for which it is used special device- pipe bender You can make a pipe bender for a profile pipe with your own hands, or you can purchase it at the construction market or in a store.

One of the simplest types of pipe bender for profiled pipes

Serial devices differ in their operating principle; they may have different types drives, however, operating any of these devices requires some experience. The use of devices manufactured in production conditions is limited by the fact that they are not cheap. A good solution in all such situations would be to independently manufacture a device designed for bending profile pipes, for which you can use improvised means.

Required design elements

The operating diagram of a pipe bender is very simple

To make a pipe bender with your own hands, you can use drawings of various designs. Their choice is determined mainly by what materials you have. Most often they opt for front-type pipe benders, the design of which includes:

• three rollers (shafts), which must be metal;
• drive chain;
• axes of rotation;
• a mechanism that will set in motion all elements of the device;
• metal profiles from which the frame of the device will be made.

Very often, a machine for bending profile pipes is made with rollers made of wood or polyurethane. When choosing such materials, you should take into account the strength characteristics of the pipes that will be subject to bending. If we neglect this requirement, then the working elements homemade device They may simply not withstand the load and collapse.

To understand how to bend a profile pipe on a homemade device, it is important to understand the technology used for this process. As a rule, pipe benders use the rolling or rolling principle, which minimizes the risk of kinking and damage to the pipe.

To make a bend on a profile pipe using such a device, it must be inserted between the rollers of the pipe bender and turn the handle. The use of such a simple bending device allows you to obtain bends on a profile pipe that fully comply with the specified parameters.

Pipe bender using a jack

To make a simple machine for bending profile pipes, you will need the following structural elements:

• ordinary jack;
• metal profiles and shelf necessary for making the frame;
• springs with high strength;
• shafts in the amount of 3 pieces;
• drive chain;
• a number of other structural elements.

When using such a device, the operation of which can be seen in one of the videos below, the pipe is laid on two side rollers, and a third one is lowered on top of it, creating the required force. To give the pipe the necessary bend, you need to rotate the handle that drives the chain and, accordingly, the equipment shafts.

Pipe bender manufacturing process

To make a device for bending profile pipes, you must perform the following procedures.

• Prepare a reliable frame, the elements of which are connected by welding and bolted connections.
• Using a previously prepared drawing, install the axis of rotation and the shafts themselves, two of which are located above the third. The bending radius of the profile pipe depends on the distance at which the axes of such shafts are located.
• To operate this bending mechanism, a chain drive is used. To complete such a transmission, it is equipped with three gears, and the chain itself can be picked up from an old car, motorcycle or other equipment.
• To operate such equipment, a handle is needed that is connected to one of the shafts. It is through this handle that the required torque is created.

Instructions for making a pipe bender

Making a pipe bender for a profile pipe yourself is not at all difficult if you adhere to the following technological sequence.

• Gears, bearings and rings are placed on the pressure shaft, which are connected to it using a key. First, a drawing of such a shaft, races for bearings and rollers is developed, then these parts are turned, which is best entrusted to a qualified turner. Total for of this device it is necessary to make three shafts, one of which is suspended on springs, and the other two are located on the sides.
• Then it is necessary to drill holes in the rings, which are necessary for making grooves and threading.
• Now you need to make a shelf, for which you use a channel, in which you also drill holes and cut the threads required when installing the pressure shaft.
• After completing the preparatory measures, the entire structure of the equipment must be assembled, for which welding and bolted connections are used. First of all, the frame is installed, which also serves as the legs of the pipe bender.
• The next step is to hang the shelf with the pressure shaft attached to it, for which springs are used. After this, you need to install side support shafts on the homemade pipe bender, on one of which a handle is attached.
• The final touch is to install the jack on the pipe bender.

Some subtleties of implementation installation work:

• the pressure shaft, fixed with keys, is additionally screwed to the shelf;
• installation of the pressure shaft is carried out according to the following scheme: the shaft is installed on a shelf to which nuts for the springs are pre-welded; after the installation work is completed, the shelf is turned over and suspended on the springs;
• the chains are tensioned using a magnetic corner, which is used as a holder;
• when tightening the sprockets, keys are used, which are pre-made from Grover;
• the drive handle for the bending machine is made with a rotating tube;
• The jack on such a homemade device is installed on a suspended platform, for which bolted connections and welding are used.

Manufacturing of hydraulic pipe bender

On the Internet you can find many photos and videos of how to make your own device for bending profile pipes with a hydraulic drive. The process of manufacturing such a pipe bender, equipped with a hydraulic cylinder, injection device and pipe stops, is a rather labor-intensive undertaking.

In the drawing and in the design of such a pipe bender, the following elements can be distinguished:

• hydraulic jack with a lifting capacity of at least 5 tons;
• shoe;
• rollers in the amount of 2–3 pieces;
• powerful metal channel;
• thick metal plates and other parts.

To make the required bend of the profile pipe using hydraulic device, you need to insert it into the shoe and fix both ends. After this, you need to use a jack, which, with its rising rod, presses on the roller, which acts on the pipe and bends it. Once the required bend angle is obtained, the process can be stopped and the pipe can be removed from the pipe bender by turning the jack handle several times in the opposite direction.

To make your own hydraulic bending device for profile pipes, a photo of which can be easily found on the Internet, you must perform the following procedures.

• Based on the drawing or photo, a structure for mounting the shoe and rollers, as well as the equipment frame, are made.
• A metal plate is attached to the lower platform on which the jack will be installed. After this, such a device is secured with bolts and a drive handle is installed on it.
• The most important thing is to find suitable rollers for the profile pipe, which should tightly grip the working part. If desired, rollers for the profile pipe, which are installed on the channel at the same height, can be made with your own hands. The shoe is installed below the rollers, and their relative position is determined by the required bending radius.
• To fix the rollers and shoe, bolts are used, the holes for which are made according to the dimensions indicated in the drawing.

Methods for bending pipes using a homemade machine

The question of how to bend a profile pipe using a homemade pipe bender is unlikely to confuse you if you read a few more recommendations. Hydraulic machines can be used to successfully bend profile pipes made of different materials, as well as thick-walled products. This operation can be performed using either a cold or hot method, which involves preheating the pipe section.

Thus, a manual hydraulic bending machine can be used to influence the pipe in two ways:

Another variation with a jack

Cold bending is the simplest bending method, which is used for pipes made of plastic materials. The subtlety of this process is to fill the pipe before the flexible pipe with sand, salt, oil or cold water. This allows you to get a better bend without significant deformation of the pipe.

If you are interested in the question of how to properly bend a profile pipe with thick walls or made from materials of increased rigidity, then the answer to this question is to use the hot bending method.

The question of how to bend a profile pipe as accurately as possible and without unnecessary labor costs will be answered by several useful tips from qualified specialists.

Removable casters different shapes will allow you to work comfortably not only with profile pipes, but also with round ones

• In manual pipe benders for bending profile pipes, you can not use sprockets, but assemble a structure based on one drive roller. Instead of a pressure screw, such pipe benders often use a jack.
• If you are bending according to a template, then to prevent the pipe from sliding off it, you can use metal hooks as stops.
• If you need to bend a profile pipe under a large radius, it is best to use a pipe bender with three rollers.
• To get a more versatile bending machine, you can make its thrust rollers movable. This way you can change the bend radius of the pipe.

In order to strictly observe the dimensions of the required pipe bend, it is best to perform this operation using a template made of wood. Even the simplest manual pipe bender using such a template will allow you to bend a profile pipe with precise compliance with the specified parameters. By the way, such templates are mainly made to implement the simplest manual methods flexible.

Homemade pipe bender for a profile pipe: device and manufacturing nuances

The need for reliable and simple device for bending profile pipes occurs when a home craftsman begins to seriously work with metal. A frame for a gazebo, a carport, a garden bench, a workbench...

These and many other designs turn out strong and beautiful if the profile metal for them is carefully bent on a special profile bender.

There is always an economical alternative to buying a ready-made machine, since you can make a pipe bender for a profile pipe with your own hands in a home workshop. Before the first workpiece is clamped in a vice, we invite you to get acquainted with the principle of operation and the existing varieties of homemade pipe benders.

How does a pipe bender work?

The operating principle of this device is simple: a profile pipe is placed between three support shafts. The central shaft creates pressure that bends the metal at the desired angle.

A pointing machine is used to bend the pipe in one local area.

If you need to get an arched profile, then use a rolling bending machine that combines metal bending with broaching.

Types of pipe bending machines

Depending on the drive that transmits force to the profile metal, there are three types of pipe benders:

• mechanical (pressure is created manually using a central screw or lever);
• hydraulic (a hydraulic jack is used);
• electric (bending force is created by an electric motor);
• electrohydraulic (the hydraulic cylinder is driven by an electric motor).

It should be noted that a rolling pipe bender with manual profile pulling is designed for small cross-section pipes (maximum 40x40 mm). It is impossible to stretch a large profile manually. To bend it, powerful machines with an electric broaching mechanism are used.

How to make a bending machine with your own hands?

The basic principle that should be followed when developing a drawing for a homemade pipe bender is maximum simplicity of design and reliability.

A machine for point bending can be assembled from two pieces of channel, four corners and two trimmings of fingers from tractor tracks.

Pipe bending in it is performed by a standard hydraulic jack with a force of at least 5 tons. A steel “shoe” is installed on its working rod. You can order it from a turner or make it yourself from an old pulley, the width of the “stream” of which is equal to the width of the profile pipe. By cutting off a half from the pulley and drilling a seat for the jack rod in it, a hydraulic drive mechanism is obtained.

bed homemade device consists of four corners (60-80 mm shelf) welded to a steel plate. Two channels are welded in parallel to the upper ends of the corners. Holes are drilled symmetrically in their walls to adjust the bend angle of the workpiece.

The manual machine for bending profile pipes is brought into working position very simply:

• Two steel fingers are inserted into the holes on the channel and stop rollers are placed on them.
• The jack with the shoe is raised so that a profile pipe passes between it and the stops.
• Having installed the pipe, use the jack handle to create a bending force.

It is also quite possible to build a rolling manual pipe bender for a profile pipe on your own. To make it, you will need 2 linear meters of channel (wall height 15-20 cm), from which the base and racks are cut.

To make rollers, take six short scraps steel pipe. It will act as a cage for bearings. Therefore her inner diameter must be equal to the outer diameter of the bearing. Having ordered three shafts from the turner for attaching the bending rollers, they begin welding the frame.

For the machine under consideration, the role of a guide setting the angle of bending of the profile is played by the rightmost support. It is mounted on a channel, pivotally connected to the main frame using ordinary door hinges. The jack's working rod rests against the turntable and lifts it.

By rotating the handle mounted on the intermediate stop shaft, the profile is pulled through the machine.

You can adjust the bend radius of the profile not only by tilting the rotary channel, but also by using the outermost rollers. To do this, they are not tightly welded to the frame, but made movable (holes are drilled in the channel and support plates).

Instead of a hydraulic jack, you can use a screw automobile jack to lift the end drum.

How to make a profile bending machine with your own hands

When arranging a site or preparing for the dacha season, the need arises for arches made of profile pipes. They are needed when constructing a greenhouse, assembling a gazebo or canopy. It is expensive to buy already bent arches - the price is twice as high as for the same flat rolled products. The solution is to do it yourself, and to make the process easier (it’s very difficult to do by hand) you need to make a pipe bender for the profile pipe. You will need channels or corners, rolling rollers and some other details. Among the tools - a grinder with a metal disc, welding machine, ruler.

Profile bender design

The machine for bending profile pipes is structurally different from the usual one. This is due, firstly, to the greater resistance of the profile to bending loads, and secondly, to the fact that the bending radius usually required is large. Therefore, the design contains three rollers. Two of them are installed permanently, one remains movable. Using a movable roller, the radius of curvature changes. In general, there are two types of pipe benders for profile pipes: with a middle movable roller and with an outer one (right or left - as desired).

You can make a pipe bender for a profile pipe in different sizes with your own hands

Pipe bender with middle movable roller

The two outermost rollers are fixedly mounted on the body. They are raised above the plane of the base. For the middle roller, a special U-shaped frame is welded. A long, large-diameter clamping screw is installed in the middle of its jumper. A third bead is attached to the lower end of this screw (can be welded). By rotating this screw, the roller lowers and rises, changing the bending radius of the profile pipe.

Design of a pipe bender for a profile pipe with a movable middle roller

A cloud is welded to one of the stationary rollers, with the help of which the pipe is rolled through the machine. To make it possible to apply less effort for rolling, two stationary rollers are connected using a chain. To effectively transmit torque, sprockets are welded to the rollers (possibly from a bicycle), and a chain is selected for them. This simple mechanism makes bending a profile pipe much easier.

With extreme movable roller

In this design, the right or left roller is made movable. It moves along with part of the base. This part is connected to the rest of the frame using powerful metal hinges.

Drawing of a bending machine for profile pipes with a lifting platform

You can change the height using a jack, as shown in the drawing. The height of the platform in this case is selected depending on the height of the jack. The bending radius is changed by lifting the movable part of the table.

Pipe bender for profile pipe with lifting platform

Unlike the previous design, this pipe bender for a profile pipe is driven from the central roller - a handle is welded to it. To reduce the required force, you can also weld the sprocket to two fixed rollers and transmit torque using a chain.

What materials and design details are needed?

The base of the pipe bender is made from a channel or two welded angles. The thickness of the shelves is at least 3 mm; select the width of the shelves and the back of the channel to match the existing parts. One rule - the base must be massive and reliable.

Several holes can be made along the edges of the platform. Through them you can fix the machine to some heavy base using large diameter self-tapping screws. Fixation is necessary, since when bending pipes with a thick wall, significant forces have to be applied and it is more convenient to work if the machine is firmly fixed.

This is what the frame looks like with welded racks for attaching the movable roller

A few words about rollers. They must be made of good, high-quality, preferably hardened steel. It is on the rollers and on the axles that hold them that most of the load falls.

It should also be said about the shape of the rollers. They should not be smooth - there should be rollers along the edges that will prevent the pipe from “walking” during rolling. Only under such conditions will the arc from the profile pipe be smooth and not twisted. Ideally, each pipe size needs its own rollers. But then the design becomes more complicated - they must be made removable, and a reliable method of fastening must be thought out. The second option is to make videos of complex shapes, such as in the photo. Carve several steps for different pipe sizes.

Rollers for bending profile pipes of different widths

The same photo shows that top part the bed is uneven, but toothed. With the help of such teeth, the rollers can be rearranged to different distances and thus also adjust the bending radius.

In general, homemade bending machines for profile pipes are assembled from what is at hand or what they can find/buy inexpensively. Those who have the opportunity grind out the rollers and insert bearings. Those who do not have such an opportunity use what they have - even bushings from bicycle wheels. In general, you need to understand the design and

Tricks to make pipe bending easier

To make the rollers move better, bearings are used. But, in principle, for a homemade pipe bender, which will be used only occasionally, you can simply make holders from a corner or channel. Make a hole in them that is slightly larger in size than the axis on which the roller will be mounted. Pass the axle with the roller on through the holes of the holders and somehow fix them (at least weld on a couple of points that will be stoppers). During operation, for better performance, lubricate the rubbing areas with a thick lubricant such as Litol. This is not suitable for industrial and semi-industrial production, but for making arcs for a greenhouse or gazebo with your own hands it is just right.

Example of turned beads

There is one more trick that helps reduce the required force when bending a profile pipe. You can use the principle of increasing gears as in a bicycle. By the way, you can use bicycle sprockets. In this case, the handle that drives the rollers is welded to a small star. It is installed somewhere on the body. Sprockets are welded onto the shaft axis bigger size(but teeth with the same pitch). All this is connected by a suitable chain.

With such a torque transmission device, an electric drive is not needed - it will be easy to work

And one more improvement - if you constantly use a pipe bender for a profile pipe, it makes sense to mechanize it. In this case, they install a motor that operates at low speeds.

The procedure for bending a profile pipe on homemade machines

It is unlikely that you will be able to obtain the required bending radius in one go - too much force is required for this. It is impossible to create it manually. Receive the required bend in several passes:

• First, the rollers are aligned so as to obtain a slight bend, the pipe is rolled in one direction, then removed from the rolls, unfolded and inserted on the other side. It is necessary to unfold in order to obtain an evenly curved pipe.
• With the same position of the rollers, it is pulled several times until the curvature is no longer added.
• If the required bending radius is not achieved, change the position of the roller and repeat the steps again.

Rolling pipe bender with electric drive

The bend radius changes gradually, otherwise homemade pipe bender You can’t make an arc from a profile pipe. What to do if you need to repeat the same bend? Make a graduation - note to what height the roller moved, how many times it was rolled in each position. When repeated, the differences, if any, will be insignificant.

The difficulty of bending lies in the fact that there is no scale and it is difficult to obtain the intended bending radius without experience. Sooner or later you will get it, but you can spoil a lot of material in the process.

How to bend a profile pipe without a machine

There are two ways to make an arc from a profile pipe without a profile bender - using welding and a template. Let's start with welding.

Get an arc by welding

The profile pipe is cut with a grinder on one side. They are made every 15-30 cm, depending on the required radius, cross-section and wall thickness. The cuts should not touch one side - the one that will be on the outside.

Result of bending by welding

The spare part prepared in this way is bent, giving the desired bend. For reliability, the edges of the arc can be fixed by welding a rod to them. Then welding is carried out along all the cuts, welding them. And the last stage is grinding the weld spots and treating them with anti-corrosion compounds.

Using a template

Thin-walled profiled pipes can be bent by hand using templates. If you need a special shape, it can be cut out of a piece of thick plywood or chipboard and secured to the table using clamps. On the workbench where we will bend the pipes, make about 8-10 holes. The template is placed near these holes.

The process of obtaining an arc from a profile pipe using a template

The holes are repeated at one end of the pipe; with their help, the pipe is attached to the workbench. Now the free end of the pipe begins to be pulled smoothly, forming a bend that follows the shape. You need to pull smoothly, without jerking.

The template can also be made on the ground. Pipes-pegs are driven into the ground (at least half a meter deep). They form the required arc. For emphasis, two additional stakes are driven in, which are located to the side of the arc. The distance you need to step aside is slightly greater than the width of the pipe.

Pattern on the ground

Having inserted the pipe, it is pulled towards the arc. Great efforts are required, the work is hard. This can only be achieved with a thin-walled, seamless pipe. The suture has too much resistance in the seam area. It is very difficult to overcome it manually.

Do-it-yourself pipe bender for a profile pipe

Home craftsmen often use a profile pipe. You can expand your creative capabilities with the help of a pipe bender, which you can make yourself

How to make a pipe bender for a profile pipe with your own hands

If you like to create unique building structures and engineering structures, well-equipped home workshop will come in handy. When selecting specific types of equipment, you need to pay attention to the mechanisms discussed in this article. To make a pipe bender for a profile pipe with your own hands, study detailed instructions, video, photo, drawings. Using these materials, it is not difficult to implement the corresponding project.

Do-it-yourself pipe bender for a profile pipe: basic data

Before studying the working documentation and installation operation algorithms, you should accurately determine the intended purpose of the product. A pipe bender for a profile pipe with your own hands must be designed for certain forces, workpiece sizes, and materials. It is easier to establish meaningful criteria after familiarizing yourself with the parameters of devices tested in practice.

What are these devices for?

Elements of building structures of complex shape are created using different techniques:

• Fastening with bolts and screws is not always able to provide the necessary reliability. Such connections are destroyed by vibration, resulting in additional loads.
• Welding produces excessive heat, which disrupts the original structure of materials. To make the connection reliable and durable, a well-qualified contractor is required. Special equipment consumes a lot of electricity. Some technological processes use expensive Consumables, create special conditions.
• Adhesive joints have limited resistance to loads and impacts of various natures.

The disadvantages listed above are eliminated completely or partially if the workpiece is bent in the required way. To avoid damage, precise dosing of loads and speeds is required. In some places it is necessary to maintain the integrity of the walls with external supports.

To reproduce such techniques without errors, special devices and machines are used.

What engineering solutions will be used in practice?

If the strength of the materials is relatively low, it will be enough to use a suitable stencil.

The workpiece is wound onto a roller, forming the required angle

To create the necessary force, a lever mechanism is installed here. A metal pin is used to fix the free section of the pipe. It is installed in suitable grooves of the “comb” before performing work operations.

Crossbow type machine

Using this factory sample as an example, it is easier to study the design features:

• Handle (1) adjusts automatic stroke piston in the opposite direction. This solution reduces the burden on the user.
• Installed inside the case hydraulic system. When the handle is moved up and down, a force of up to 150 kN is transmitted to the working piston (8). This is quite enough for quickly bending workpieces made of durable metals.
• The support rollers (3, 4) are installed in the required holes of the open frame (5, 9). They do not damage the surface of the pipe, but provide reliable fixation.
• This removable segment (6) is designed to be bent at an angle of 90°. But with the appropriate configuration, it can be installed on a similar product of a different shape.
• The robust housing (10) is mounted on three supports (7). Rubber pads prevent the machine from moving when performing work operations.
• In addition to cleaning from dirt, you should occasionally check the condition of the oil filter (11). No other regulatory procedures are needed.

For rolling, a mechanism with three rollers is used, which are movably fixed

Run-in

In this technique, a workpiece of the desired shape is used. The pipe is pressed against it using a rotating roller and lever.

With the right choice of technology, a straight pipe can be bent as follows
Using appropriate equipment, such decorative products are created

Important! Before bending a workpiece using a certain radius, you should study specialized reference books. They provide data on the permissible deformations of pipes made of different materials, with different wall thicknesses. If these instructions are violated, visible or hidden defects will form in the finished products.

Relatively small mechanical loads on working tools are created by levers and manual force. To work with durable metals The equipment is equipped with hydraulics and electric drives.

A hand-held device means mobility and the ability to perform work in confined spaces

Making a pipe bender with your own hands for a profile pipe: drawings and other preparatory operations

A simple device for bending aluminum and plastic blanks is shown in this figure.

Such a device is not difficult to assemble quickly using available tools

To make such a structure you need a strong board. After marking it is cut out electric jigsaw round profile. The remaining part is used to make the supporting element. The created parts are rigidly attached to the supporting surface. To ensure the strength of the connections, in addition to screws, clamps are used. Next, the pipe is bent by hand until the desired shape is formed.

Before creating this simple pipe bender for a profile pipe with your own hands, it is recommended to make a basic drawing with dimensions. A template made of thick paper or cardboard on which the markings will be applied will come in handy. It is clear that to produce more complex structures it is necessary to prepare complete design documentation.

It is not necessary to strictly adhere to engineering standards in order to make a pipe bender for a profile pipe with your own hands; a schematic image is quite enough. You just need to indicate all the dimensions, decide on the materials, technological process and components. The project will help solve several practical problems:

• During the preparation process, it will become clear whether it is necessary to use welding and other special equipment.
• A complete list of necessary components will be needed for targeted visits to certain stores.
• We must not forget that the machine must be protected from adverse external influences by impregnating wood and painting metals.
• Some parts will be too difficult to make yourself. Appropriate orders should be placed in specialized workshops.

Important! When bending strong metal pipes it takes a lot of effort. In order not to take unnecessary risks, you can use drawings of a proven design, or copies of an industrial design.
