The need for use and cost of industrial pipe benders

When deciding on a profile pipe, inexperienced craftsmen often resort to manual mechanical bending, for which they use primitive structures in the form of support pins driven into a concrete slab, according to the pattern of which the pipe is bent.

However, this method has a number of significant disadvantages, the main of which is labor intensity: the profile has increased strength due to the presence of stiffeners - it is extremely difficult to bend relying only on physical strength. Note that the strength of the profile decreases due to manual bending, since it is accompanied by the application of uneven forces, which leads to an increase in internal stress in the material.

On construction market presented a large number of devices for bending profiles, however, they have an exorbitant cost, which does not allow purchasing such units for use at home. As an example we give average price on machine models from the leading company on the market – TV company:

• manual pipe bender TV-2 -12 thousand rubles;
• roller profile bender TV-4 – 30 thousand;
• pipe bender electric roller profile bender TV-10 (double-sided) – 76 thousand.

To make manual machine at home, you will need to spend about 3-5 thousand on component materials, and in terms of efficiency it will not be inferior to industrially produced products.

Making a simple pipe bender with your own hands

We bring to your attention instructions, following which you can make a manual profile pipe bender DIY pipes. The manufactured machine allows you to bend profiles with a cross-section from 10*10 to 25*25 mm at an angle of 0-180 degrees.

This simplest design, for the manufacture of which you will need the following materials:

• fastening strip with a hole 30 mm in diameter and 4 mounting sockets for M6 studs;
• a handle for rotation, which can be used as a reinforced thick-walled square profile;
• large roller with a diameter of 173 mm;
• small roller with a diameter of 65 mm;
• axis for rotation of rollers with a diameter of 30 mm and a height of 61 mm, with an M14 thread on the end part;
• washer C16 and nut M16.

The mounting strip for the machine for bending profile pipes is made of sheet metal of thickness not less than 7 mm. It is necessary to drill holes in it for installing the roller rotation axis and installing M6 studs (socket diameter 8 mm); holes are also drilled on the bar for the fixing bolts.

The handle (lever) for applying bending force is made of square profile cross-section 36*36 mm (wall thickness 4 mm, to the inner end of which two plates with 30 mm holes for the roller fixation bolts are welded. Keep in mind that the efficiency of the work directly depends on the length of the handle. Subsequently, it can be extended using a crowbar inserted inside.

For a profile pipe it is manufactured according to the following algorithm:

1. On mechanic's workbench The mounting plate is secured using M8 bolts. The workbench or table on which the device is installed must be well secured to the floor to avoid shifts during the bending of the profile.
2. Between the plates of the handle there is a large roller, which is placed on the rotation axis threaded through the mounting bar and clamped with a nut.
3. The axis of the small roller is installed and fixed.
4. M6 studs are attached to the mounting sockets of the plate, which will fix the extreme part of the profile during the bending process. Mounting plates selected according to the profile size are installed on the studs.

How to bend a profile pipe with a manufactured device? The pipe bender handle is moved to the extreme left position so that a straight axis is maintained between the mounting plates and the hole between the rollers. A profile pipe is inserted into the mounting socket and the machine lever is rotated until the bend reaches the required angle.

High-precision profile bending machine

Bending a profile pipe along a radius is performed using a more complex device, which can also be done at home. Scheme and design features accessories are shown in the image.

The bending machine for a profile pipe, it is fixed on a frame table (without a tabletop), the dimensions of which determine the size of the supporting frame. This scheme uses channel bed 10 cm high and 77 cm long.

To make a pipe bender follow the instructions:

1. From a strip of metal 5 mm thick, 4 support posts are cut out for small shafts along which the profile will move. A hole is cut out at the upper end of the racks for the axis of rotation of the rollers. Dimensions of racks – 5*10 cm.
2. The racks are welded to the channel at a distance of 30 cm from each other. Rollers for shafts can be purchased at the hardware market; such products are used when installing sliding ones. After welding, place the profile on the rollers and check whether the structure has moved during the welding process. If deformed, you will need to do all the work again.

   

3. Next, a plate is cut out of sheet metal 8 mm thick for the load-bearing part of the machine; the dimensions of the plate are 25*25 cm. We need to install a central roller on the plate, by rotating which the bending profile will move.
4. The plates are installed along the edges wooden spacers 10 mm thick, which are glued to the metal using superglue. The supports are needed so that when rotating the roller does not touch the carrier plate.
5. To install the roller you will need two bearings, inside of which the shaft axis will rotate. Good fit bearings series No. 203 from CRAFT. The bearings are secured with bolts in pre-drilled holes inside the stands.

   

6. Next, you need to make four racks 40 cm long from the 50th corner and, using welding, secure them to the corners of the plate with the central shaft, fixing it on the supporting station of the machine (channel). The plate is installed in the central part of the racks so that between the axes of the rollers there is a distance equal to the size of the profile you plan to work with.

   

7. Plugs are cut from 8 mm sheet metal and welded to the top of the racks. Next, you need to make a plate under the machine cover on which the adjusting screw will be installed. A hole is drilled inside the plate to match the diameter of the screw used (you can use grape press screw).
8. Holes for bolts (diameter 10 mm) are drilled in the rack plugs and the cover plate is fixed to the racks.
9. A thread is cut into the hole in the cover and a heel is screwed in, inside which the pressure screw will rotate.
10. A 15 mm corner is welded to the plate, acting as an external screw stop, for which a hole is drilled in the corner, parallel to the axis of the heel. A thread of the appropriate size is cut into the hole.

    

11. All that remains is to make a handle for the central shaft and fix it on the axis of rotation of the roller. As a handle, you can use a shutter bolt or a piece of fittings of the appropriate length.
12. It also wouldn’t hurt to paint the machine to make it look more presentable. The paint coating will also protect the metal from corrosion.

How to bend using a machine made? The profile is laid on the shafts, after which the central roller is lowered using a pressure screw so that it rests against the pipe. Next, the rotary handle is rotated and the shafts move the profile, which bends under the pressure of the central roller.

Having stretched the profile along the entire length, we lower the clamping screw even lower and repeat the operation, moving the profile to reverse side. The process is carried out until the bend of the required radius is obtained.

This device, which was manufactured at home, can bend a profile no less effectively than an industrially produced electric roller profile bender.

In construction there is often a need to bend metal strips or pipes. If it is not possible to visit workshops that specialize in this issue, make a pipe bender for a profile pipe with your own hands. Having a similar tool at hand, it is easy to make trellises, arches for climbing plants and grapes. It will also help in the manufacture of gazebos, canopies, extensions or greenhouses, fences and even metal frames for furniture.

What does a pipe bender look like?

A pipe bender is a special device that helps smoothly deform pipes made of steel, aluminum, copper, polyvinyl chloride and other materials. The bend is made from 0 to 180˚ if the diameter ranges from 5 to 1220 mm.

The pipe bender forms the product without damage or kinks.

Based on the installation method, a distinction is made between stationary and portable devices.

By type of drive - manual, electric and hydraulic.

Pipe bender for working with pipes and metal strips

Reliable lever or screw device

The device consists of three shafts. There are two support rollers in a static position on the frame. They are rotated by a handle mounted on the neck of one of them. The material feeding shafts move uniformly thanks to the connecting chain.

A pressure roller is installed in the guides. The screw raises the guides and lowers them in a vertical rigid frame. As you can see, the diagram of a pipe bender for a profile pipe with your own hands is simple.

The first stage in the manufacture of such a device is the formation of the frame. To do this you need to take the corners. You will also need a double-row chain and sprockets. To make a handle that rotates the shafts, a calibrated rod and wrench. For further use, a cut is put on the handle. This is done to prevent calluses from appearing on your hands.

The shafts will have to be ordered from a turner. To prevent the material from sliding to the side along the pipe bender, a special groove is made in the device according to the size of the profile (+ 2 mm). The journals are forced out on the shafts to accommodate the working bearing and sprockets. In addition, keyways for fastening will also be required. The size of the groove on the gear determines its width. The depth will be equal to half the height of the key used on the car for the same sprockets.

Rollers between which the pipe passes

To prevent the screw of the device from being worn out during operation, a copper or cast iron plate is fixed to it.

For high-quality bending, the pipe is placed on the feed rollers and carefully pressed. After this, the starting point of the radius is determined. It coincides with the center of the roll located on top. The handle is rotated in the required direction, while moving the pipe using feed rollers. At each pass, stops are made during which the screw is turned and the radius is checked.

When we make a profile pipe bender with our own hands, we carry out modernization. In order not to rotate the heavy handle, it is enough to make a drive.

Some profile benders use adjustable rollers to bend pipes.

Instead of a handle, a pulley is installed. For good rotation, it is better to use a V-belt drive. If overloads begin in the network, it will not break, but will simply stall.

The electric motor can be taken from the old one washing machine or from the pump.

By making 5-6 shaped cuts in the feed rollers, repeating the cross-section configuration, you can achieve the versatility of the device. This tool will bend not only profile pipes of various sections, but also water pipes and metal strips. The technology for making a pipe bender for a profile pipe with your own hands is similar to one standard size, only the drawings of the feed roller barrel differ.

Lever pipe bender diagram

We make one-time pipe benders

If there is no need for permanent job device, it can be simplified. From boards that are larger than the profile, we make a bending template. The finished configuration is fixed on the shield. Initially, a clamp is nailed to hold the object, then strips are attached in several places (they protrude beyond the edge of the shield and limit the rotation of the profile).

After installation, the end is inserted between the clamp and the template and gradually pressed against the surface. A rod lever can help with this.

It turns out to be an excellent pipe bender for a profile pipe with your own hands, the dimensions of which can be any.

Diagram of a pipe bender you can make yourself

For this, a hardwood tree is selected. Oak or regular pear will do. Formation wooden elements performed on home machine: mounted on the rotating part wooden block, and with a wood cutter it is given the desired shape. It is important to use the lever carefully. We perform rotating movements smoothly, without jerking.

Small pipes are flexible and soft, so wooden structure bends up to ten profiles.

If there is no chain, we help move objects between the rollers ourselves. They need to be pushed by hand along the axis. We press it with the end of a wide board, the corners of which have been previously rounded.

When making a pipe bender for a profile pipe with your own hands, it is important to understand the main principle of its operation. It consists in the fact that the device deforms parts using three points, which are located at a distance of 200-300 mm from each other. During movement, they limit the rotation of the object. Thanks to this, the profile will retain its cross-section, and the surface will remain smooth and undamaged.

Bending a pipe using a wooden template

Two pipe design

For such a tool you will need two pieces of steel. Their diameter should not go beyond 70-150 mm. The sections are concreted in a vertical position. This could be a hole in the ground or a container that has fallen out of active use. You can take a tall bucket, basin or plastic barrel. The main thing is that the distance between the tubes is 40-50 cm.

If it is not possible to concrete the pipes, they are welded welding machine to a reinforced base. As you can see, a manual pipe bender for a profile pipe, made by yourself, is simple design.

The workflow itself is also simple. The bending pipe is inserted at one end into the gap between the previously installed steel sections. After this she bends under the right angle. This method Suitable for 40mm diameter.

To bend a pipe that is too short, fittings are inserted into it and then the work process is continued.

Pipe bender with chain and sprockets

Heated pipe bender

Thanks to this method, the bend is smooth.

The essence of the process is that selected, sifted quartz sand is poured inside. It does not stick to the walls, but when hot it acts on them. The pipe is closed on both sides wooden plugs.

It should be taken into account that during the heating process gases and vapors accumulate in a closed space. To ensure they come out unhindered, small holes are made at the end.

The bending area is marked with chalk. To deform the pipe by 90°, a section equal to six diameters is heated (respectively, 45° is three diameters, 60° is four).

After heating, the pipe is carefully inserted into a self-made profile pipe bender and bent according to the template. Drawings of such a device can be found for free.

You shouldn’t stop in the face of difficulties; the problem can be solved if you approach it creatively. Of course, it is better to turn to experienced craftsmen, but when there is no time to wait for workers to arrive or there are no additional funds to pay for their labor, you can bend the parts yourself.

Video instructions for making a pipe bender

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 make this simple tool with your own hands and use it in household It is completely within the capabilities of anyone with 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 from various materials– aluminum, metal-plastic, stainless steel. The bend is made according to the required shape and dimensions.

Types and models of pipe benders

Industry produces Various types professional pipe benders. Not for bending pipes large diameter, as a rule, a tool with manual drive, 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 thickness walls 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 self-production pipe benders 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 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.

Rollers can be turned on lathe. Also, the roller can be cut with a jigsaw. To do this, circles of different diameters are cut out of hard plywood with an inclination 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 primarily of 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 more universal tool, at the design stage it should be possible to install the side rollers in different positions.
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 fit a couple of diameters of round pipes and 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 details on " 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.

When installing most metal structures, bending of pipes is required different angles. A ready-made device for this can be bought at hardware stores, but what if it is unlikely to be useful anymore? Is it worth spending money on a mechanism if it will later gather dust on a workshop shelf? The simplest and most logical solution is to build the device yourself. How to make a pipe bender for a profile pipe? Recommendations experienced craftsmen and video instructions in this article.

A self-made device will help you give the product any shape.

Rolled metal, bent at a certain angle, is necessary in many structures. Among them:

• engineering communications in residential buildings: water supply, sewerage, ventilation;
• fencing around the perimeter of the site;
• home and garden furniture;
• greenhouses;
• gazebos and canopies.

You can bend any rolled metal, the main thing is to use the right tool for this purpose. You can give the required shape not only steel structures, metal-plastic, copper, aluminum can be bent.

Helpful information! To select a pipe bender, you need to take into account not only the cross-section of the product, but also its profile. Simple round pipes can be bent much easier than profile ones. If handled incorrectly, the latter can become significantly deformed or even break.

To use the tool correctly, you need to carefully study the advice of professionals in the video. A do-it-yourself pipe bender for a profile pipe can be made in a simple, manual version or using hydraulics.

Hydraulic devices quickly and efficiently bend any metal parts.

A conventional front pipe bender consists of the following elements:

• three metal shafts;
• drive chains;
• rotating axis;
• rotary mechanism;
• frames made of metal profile.

Sometimes the shafts are made of wood or plastic, but it is worth taking into account that such rollers will not cope with any pipe. If you do not calculate the resistance of the material, the shafts may simply collapse.

How does the profile bending device work?

Before you start making a homemade pipe bender for round pipe or profile, you need to understand the operating principle of the device. The action of the mechanism is based on rolling or rolling. This principle helps eliminate the risk of accidentally deforming and breaking the material. To give the metal the desired shape, it is inserted between the shafts and the handle of the device is turned. The result should be the desired bend.

Do-it-yourself pipe bender for a profile pipe: types of devices

The devices differ in purpose. There are devices for forming turns on steel, metal-plastic, copper, and aluminum products.

Devices can be portable or stationary. Portable models are convenient because they can be installed directly in the room where communications are being installed. Stationary machines used in production.

Note! Incorrect use of the machine may result in changes internal diameter pipes, surface wrinkles and changes in wall thickness.

Manual pipe bender

Soft materials, metal-plastic and copper, bend easily manual device. Its design is quite primitive. The bender itself does not take up much space and can easily fit in a small workshop. In addition to the pipes themselves, you can bend reinforcement or rolled metal on it.

Hydraulic device

This device is capable of giving the required form material with diameters up to four inches. Profile material using hydraulics it can make intricate bends, repeating the relief of the wall.

Making a pipe bender with your own hands for a profile pipe: drawings and diagrams

The simplest device consists of a frame, slats, and two stops. If necessary, a hydraulic system can be added to it. IN complex structures a power supercharger and additional levers are used.

An example of a diagram of pipe benders for a profile pipe with your own hands:

Helpful information! Metal parts of the structure must be thoroughly lubricated to protect against rust. You can even provide a special compartment for automatic feeding lubricants

Model No. 1 – rolling

Assembly algorithm:

• The metal base must be secured to a level durable surface and drill holes at the ends.
• The steel rectangular plates must also be drilled to secure the rollers.
• Secure the plates to the base with nuts and bolts.
• Install rollers in the grooves the right size and fix them firmly.
• In the center of the base, weld the stands for the central shaft and secure it with a stud and nut.
• Provide one shaft with a handle for turning.

Result: You should get a design like in the photo. You can not use a metal base, but attach the plates directly to the base.

Model No. 2

Another pipe bender for a profile pipe with your own hands, of a simpler design, will cope with products with a cross-section of two and a half centimeters.

Work order:

• It is necessary to make a device template on paper.
• From scraps of lumber, assemble the device according to the template, fastening the parts with self-tapping screws.
• Screw the resulting module to the wall. Screw a beam onto one side of the module for support.

Advice! When screwing parts, you need to focus on the diameter of the pipe. It should be easy to insert and lock into place.

Result in the photo:

Model No. 3

This version of a do-it-yourself pipe bender for a profile pipe is even simpler:

• A sheet of plywood is screwed to the wall, and the desired bend is depicted on it.
• Metal hooks are secured along the line with screws. Metal plates must be attached to each hook; they will additionally secure the material being bent.
• It is necessary to provide a stop for the end of the pipe.

Advice! If you don’t have enough strength to manually perform the desired bend, you can use a winch.

Result:

Application of hydraulics

For a hydraulic device you will need:

• rollers – 2 pieces;
• hydraulic jack;
• shoe;
• channel;
• steel plates.

The jack is fixed on the workbench. It will push the pipe into tight gripping rollers. If you prepare rollers of different diameters, you can work with products of any size.

Video: do-it-yourself manual pipe bender for a profile pipe

To construct a pipe bending device, you can use ready-made drawings. The video “How to make a pipe bender for a profile pipe with your own hands” will reflect the manufacturing procedure and how to use the resulting tool.

• For bending, rolled metal must be heated, especially with outside diameter

• To prevent deformation, the pipe must be filled with sand before bending.

• If you are not sure of the result, don’t try it. Sometimes it is easier to buy ready-made bends and weld them to the pipe than to correctly give it the desired shape.

Drawing conclusions

It is quite possible to make a simple device for bending rolled metal with your own hands. If you need to manufacture a complex configuration metal structure, it is better to use the rolling method. For a couple of simple bends, a device using hooks is suitable.

It is worth remembering that the wrong ratio of force and excessive haste can lead to irreparable deformation of the material.

Pipe bender - very useful tool on the farm, if you are used to doing everything with your own hands. 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 the construction market you can purchase various 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.

A pipe bender is made in a similar way from concrete slab and durable 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. For bending flexible pipes rollers can be cut from wooden blanks hard rocks. Rollers can be made on a 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 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 become good help In workshop home handyman. 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 the pipes 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.
