By far the most reliable option fastening connections - one-piece, and, having special tools on hand, you don’t have to think about the question of how to rivet a rivet. Next we will tell you exactly how such fasteners are made.

1

What is this fastener? Initially, historically, it was a metal rod, less often a plate. Always with a locking head on one side (a cap that limits the movement of the element in the hole) and a locking head on the other end. It was first used for the manufacture of armor, such as plate and chain mail, as well as for connecting some elements of edged and early firearms. If the embedded head is present initially, then the closing head appears as a result of the process of upsetting (riveting) or with the help of a special tool due to deformation with a pulling rod. It is logical that the upset applies to cast or stamped all-metal elements, and deformation by a rod is possible only when using hollow (tubular) blind rivets. There are also explosive and cutting options.

Various types of rivets

So, we know that the fasteners we are considering are one-piece, which often ensures high reliability. But the strength of the connection depends primarily on the material, so we will first consider the types of rivets according to this characteristic. The most common are aluminum fasteners, in many production processes, and also in a number of crafts, copper and brass rods are used. All these materials do not have a high degree of reliability and are suitable only where there are no heavy loads, for fastening decorative parts. Among other things, there are steel rivets, including stainless steel, they provide a fairly strong connection and are even suitable for the assembly of load-bearing structures and mechanical engineering.

Very important during installation metal parts use rivets made of the same material as the elements being connected.

Before using rivets, you need to know how to rivet certain parts correctly. There are many connection methods, but they are usually divided into 3 types. Durable fasteners are used exclusively where certain loads are present. Sealed, as the name implies, are needed to ensure tightness at the joints of sheets or any parts. And finally, tightly sealed ones perform both functions. It should be noted that for the second type, that is, for hermetic rivets, the embedded heads are made reinforced.

Blind rivets

The most common connection method is overlapping, and it is applied not only to, but also to parts complex shape. This option is also called single-cut. Under the influence of multidirectional loads, for example, when stretching, such a seam can easily deform. A more durable joint is a butt joint, using one or two (on both sides of the seam) overlays, but this option, also called multi-cut, makes the structure heavier and leads to greater consumption of material. Installation of rivets during fastening can be chain or staggered; the second is more reliable, but very labor-intensive.

Mortgage heads come in the most different forms. The most commonly used ones are semicircular and hidden. The former completely cover the hole, like the head of a screw, and for the latter, the channel is flared so that the head, shaped like an inverted cut cone, fits completely into the hole. In the second case, the surface of the part remains smooth, since the riveting occurs flush, and the destruction of such rivets becomes difficult. There are also semi-flush form factors (with a small rounded convex), flat, flat-conical, conical and oval.

The most commonly used today are pull-out riveting elements, which are especially convenient if you need to attach a part to a surface the opposite side of which is inaccessible. They are a tube with a flaring at one of the ends (analogous to a mounting head), in the channel of which there passes a rod with a cap at the flat end of the riveting. On the flared side, a large part of the rod is extended, with which the tool clamp engages, for subsequent pulling through the tube. Its straight end is crushed by the head of the rod and forms a closing head.

Rivets for metal

However, it should be taken into account that when two parts are connected, its channel also expands, so the edges of the holes must be strong and not subject to deformation. Therefore, for fastening plates from soft material, whether plastic or aluminum, steel inserts or washers must be used on both sides of the connecting parts. The same applies to connections that must be movable, hinged; they can also be used in combination with bushing washers, and their length must exceed the total thickness of the plates being fastened.

4

Unlike pull-out elements, conventional cast or stamped riveting elements must be installed using a certain amount of force applied to the closing end. This can be pressing or targeted blows to flatten the end of the rod coming out of the hole. The second option is most reminiscent of forging, especially since it is performed cold or hot. If the thickness of the riveting does not exceed 1 centimeter, you can use a cold forging of the closing head. If the diameter is more than 10 millimeters, then the fastening element must be heated to facilitate flattening of its end.

Rivet tool

As a rule, before hot riveting a rivet, it is heated in a forge, after which it is installed in the hole and a flat closing cap is made with several strong blows. In this case, there should be an anvil with a hole for the mounting head located below. For the cold method, a special tool is used - a striker with a semicircular hole, with the help of which an even hemisphere is formed by deforming the end coming out of the hole within the recess. Forging with a regular hammer gives the same result if you hit it on the end, directing the blows slightly sideways, from the center to the edges, but such a head will be less accurate.

5

As we have already said, the type of connection under consideration is one-piece, however, if you still need to disassemble a structure whose parts are riveted together, you can use several different methods. The most common one, which is usually applied to pull-out, explosive and split types of fasteners, as well as where countersunk heads are used, is drilling. To do this, a drill corresponding to the estimated or precisely known diameter of the hole is installed exactly in the center of the embedded or closing head, after which a hole is made to the required depth or a through channel. After this, with a few precise blows you can easily knock out the rivet.

Rivet Removal Tool

The second method is somewhat labor-intensive, however, it is quite effective for heads that are clearly visible above the surface, that is, for semicircular and conical ones. You will need a special chisel, shaped like a chisel, with which you need to cut off the cap, delivering sharp and strong blows to the back end of the handle. A sharpened chisel may also work, but this tool is recommended only for small-diameter rivets. Fasteners with a rod of about 1 centimeter or more are very difficult to cut in this way.

The easiest method for removing rivets with protruding heads is to use an angle grinder, commonly referred to as an angle grinder. It is best to install a cutting disc on it for this purpose, and, moving it from the side to the head, carefully cut it off. If there is a possibility of damaging the surface of the part from which the connection is being removed, it is recommended to use a coarse grinding disc, with which the head is simply carefully ground down to the base. Next, by installing any sufficiently sharp tool, for example, a punch, you can easily knock the rivet rod out of the hole with a strong blow of a hammer.

Rivet and Riveter. Riveter and rivet device. How to work as a riveter. Tool.

Chapter . Construction tool

A riveter is a tool designed to perform riveting work. Rivet connections are a permanent connection of two or more parts by filling the connecting hole with some kind of metal. IN classic version- make an adjacent hole in the parts and countersink it from opposite sides. A small piece of soft metal is inserted into the hole and flattened so that the metal fills the entire hole and the recesses of the countersink. The “hats” formed in this way hold the parts together. Of course, with the help of a rivet you can seal (rivet) a hole just in one part.

Rivet connections are very reliable and, most importantly, very vibration-resistant. The rivet will never burst "suddenly" when the tensile load applied to the parts increases. This distinguishes connections using rivets from welding, which breaks all at once. The rivet will “stretch” at first. What sets a rivet apart from a screw connection is its low cost, since the rivet itself is just a small cylinder soft wire. Of course, with the advent of automatic machines, wire blanks began to be made in the form of blanks for riveting.

The classic riveting process requires access to the rivet from both sides. After all, the effort to forge metal is quite significant. If the parts are small, the part is placed with its finished head on the anvil, and if it is large, a stop is placed on the side opposite to the forging. This was extremely inconvenient and made the hardening process actually the preserve of professionals or industrial production.

But modern rivets (so-called blind rivets) only allow work on one side. Which made rivet work very accessible and popular. All this happened thanks to a change in the design of the rivet and the appearance of a special tool - a riveter. Modern construction rivet It is a small tube with a finished cap on one side (Fig. 3). A piece of wire is inserted into the tube, also with a cap on the other side. If this wire is pulled through this tube with force, then the strong head of the wire will flare the tube. And when the head of the wire hits the part, the wire will simply break, and the tube will remain flared. For connecting thin parts into which it is impossible to securely screw a self-tapping screw or make a screw connection, rivets are simply irreplaceable.

The riveter itself is a manual lever mechanism with a high lever arm ratio. The drive is carried out by a collet mechanism, which grabs the rivet wire, and, resting against the finished rivet head, pulls it towards itself and breaks it off. The design of the shoulder pads can be simple, but there are also some with “conveniences”. For example, in the form of a rotating collet head, allowing the use of a riveter in hard to reach places. Since rivets come in different diameters and lengths of the rivet tube, the riveter has a set of interchangeable heads for different diameters wire.

The process of installing the rivet takes about a couple of seconds (if the holes in the parts to be connected are ready). Let's show this with an example.

Let's say you need to connect two parts made of fairly thin metal, and access to them is only from one side. Well, for example, you need to attach (conditionally) handles or legs to a barrel... You can’t cook (the metal is non-ferrous and dissimilar), self-tapping screws will not hold in thin metal (they need at least 1.5-2 “threads”, i.e. . thread revolutions). Soldering is impossible, the parts are massive. Gluing is unreliable; adhesives work well for shear, not tearing. All that remains is to rivet...

1. Having attached the parts to each other, we drill a through hole in both parts.

2. Insert a rivet into the hole. The length of the rivet tube should be such that it protrudes from the opposite side by about 1 cm. There is no point in more, and less - there may not be enough metal to flare and form a reliable head.

3. We put the head of the riveter on the protruding wire, press it to the head and press on the handles.

4. We do this several times until the wire breaks. The rivet is ready!

5. Since this is just an example, let's see what the rivet looks like from the opposite side. Quite a neat head too.

The remaining head of wire in the flared tube can be knocked out using a torn piece of wire. Then, in place of the rivet, a small neat hole is formed, rolled with a rivet. This rivet can be used for cutting threads in thin metal. Those. if we need to do threaded connection in thin metal, we first drill a hole, rivet it, and then, knocking out the head of the wire, cut a thread in the rivet.

The use of a riveter (and riveting technologies) greatly facilitates some construction and installation work and allows you to quickly make reliable connections between various parts.

There is a large number in various ways connect two metal pieces together. Welds are often used. They are quite reliable, but lead to some deformation of the material from heating, which is unacceptable in some cases. This is why rivets are required. Aircraft and other vehicle bodies are completely assembled using rivets. In addition to the usual expansion rivets, there are also threaded steel rivets. They also have wide application. The types of such consumables and the riveter for them will be discussed in this article.

Types of rivets

The connection made using rivets is permanent. The appearance of this type of joint may vary. It depends on what kind of rivets were used in the process. The appearance is determined by the conditions in which a particular connection will be operated. Most often, the connection with rivets is required to be sealed so that water or cold air did not get inside the object or room. To achieve this result, rivets are often arranged in several rows. Their installation is carried out using manual or electric tools. Manual riveters make it possible to complete a limited amount of work within a certain time frame. With power tools, volumes and quality increase.

Note! There are various attachments available for drills and screwdrivers that allow you to quickly install a rivet.

The algorithm for creating a joint with rivets comes down to choosing a place for fastening, drilling a hole and fixing the equipment. With the use of such fastening material, there are practically no restrictions on which elements can be fixed to each other. In this case, the structure of the components remains without damage. The downside for many is the labor-intensive process, which involves using various instruments. In some cases, additional sealing of the seams is required. In terms of time, it takes a longer period of time than welding or using self-tapping screws.

Rivets differ in the method of fixation and the tool that is needed for this. Initially, the fastening material was a small cylinder of metal. To fix parts with it, it was necessary to gain access to two sides of the part. The main tool was a hammer, which was used for riveting. The most common option for this moment is the use of tubular fasteners or blind rivets. Fixation with their help is carried out by a manual or automatic riveter, which pulls out a rod with a thickened tip. The latter flares one of the parts. This does not require access from the second side.

Another option that is widely used in manufacturing today is screw or threaded fasteners. In appearance, the clamps resemble a hollow tube with a thread. To process it you will need a special riveter. A rod is mounted into it, and it itself is placed inside the rivet. After squeezing the handle outer part The riveter holds the latch inside, preventing it from moving. In this case, the rod is pulled out, which compresses the rivet, increasing its diameter and locking it tightly in the hole. This installation method can be divided into two workers without much difficulty. One of them drills holes and inserts rivets, and the second crimps them with a tool.

Threaded riveter

During deformation of the fastener, the riveter's task is to maintain the internal thread. If this is not done, then the tool cannot be removed back. The thread riveter can be used not only for metal, but also for plastic workpieces. This is due to the minimal load that the fastener exerts on the material after deformation. IN modern practice Manual and pneumatic riveters are used.

Kinds

Threadlockers can be found in the range of many tool manufacturers. The most common riveters with manual mechanism fixation. This is due to their relative cheapness. They apply force according to the principle of leverage. Thanks to the elongated handles and mechanism, the force from the user's muscles is transferred to fastener. If desired, a riveter for threaded rivets You can assemble it yourself, because its mechanism is not too complicated. Among the hand-made specimens there are:

• one-handed;
• two-handed.

The first is suitable for rivets whose diameter does not exceed 5 mm, and the second for rivets with a diameter of 6.4 mm. This is due to the maximum force that can be applied to specific instrument. Pneumatic riveters are often used in manufacturing. They make it possible to increase the processing speed of parts several times. But such a device requires additional modules for normal functioning. The main one is the compressor for injection compressed air.

Method of use

Working with such a riveter does not require special skills and abilities; it is important to simply understand the principle. The first stage is the preparatory stage. Its task is to bring the surface of parts to the required state. In order for the fixation to be reliable, the surfaces must be smooth and adjacent to each other without gaps. In some cases you will need to use grinding machine or a file to remove paint residue or burrs. The next step is to make a mark in the place where the hole will be located. To do this, you can use a scriber and a punch, which will create a small recess for the drill so that it does not jump out of its place.

Next, a hole is drilled. This is a critical stage, because it must be strictly perpendicular without distortions. If this requirement is not met, then it will be difficult to insert the rivet. It is important to choose the right drill. Its diameter should be slightly larger than the diameter of the rivet. If there is a need to install a rivet with a diameter of 6.4 mm, then the drill should be 6.2 mm. The length of the rivet should be several millimeters greater than the width of the parts that will be fixed. The rivet head is placed inside and the fastener is compressed. The force must be maximum for the fixation to be reliable. An overview of such a tool can be found below.

Self-assembly of the tool

There are no particular difficulties in assembling a threaded riveter with your own hands. To do this you will need a bolt and nut. The bolt thread must have such a pitch and diameter that it fits freely into the rivet. The nut is fixed to the bolt so that it does not jam during operation; you can use a small bearing, which is also placed on the bolt. The essence of use is that the bolt is placed inside the rivet. The nut is unscrewed until it secures the rivet head, after which it is necessary to begin rotating the bolt. As it passes, the rivet will compress and fix the parts. To make it easier to use the tool, you can take a bolt with an internal hex head into which you can insert a lever.

The disadvantage of such a device is the complexity of its use. In some cases, the bolt may become stuck in the fastener and will be difficult to remove. This effect occurs when the bolt is made of a soft material. A homemade threaded riveter is perfect for one-time use. If there is a need to constantly work with threaded rivets, then it is better to acquire factory tools. A video about a homemade riveter is below.

Summary

The thread riveter is definitely the right tool, if there is a need for constant work with workpieces that must be connected without using welding machine. If you need a one-time job, you shouldn’t spend money on buying a factory tool; it can be easily built from scrap materials.

Quite often, home craftsmen fasten various metal connections together; this is where hand riveters become very relevant, because it is with their help that the connection is made quickly, firmly, and without much physical effort.

Introduction

It should be noted that this mechanism very easy to use, and the regular model is inexpensive. It can be used to fasten any type of metal, and the principle of operation remains the same.

Of course, you can make a rivet with a hammer, but with a large amount of work it will require much more time and effort. Manual riveters make the work process faster, and the effort required for all operations is minimal.

Today, there are different types of manual riveters, each working on its own principle and having its own pros and cons. Which type of riveter is better is determined by each master himself, but several points must be taken into account, which we will consider below.

general description

Modern riveters appeared relatively recently; before that they were bulky and inconvenient for home use. But Full time job engineers working on this problem has yielded results: manual riveters have become compact, and most importantly, they reliably connect parts with each other with minimal physical effort. The device itself has become quite simple and easy to use.

It provides access to both sides for a more reliable connection. In this case, no outside help is required. The main thing you need when working with manual riveters is pre-drilled holes for rivets in the parts to be joined.

Almost anyone can cope with such work. At the same time, the price for manual riveters is low.

Types of hand tools

Today there are two types of manual riveters: pull-out and threaded, the difference in price is not big.

To answer the questions: how to choose a manual, pull-out or threaded riveter, which tool is better, you need to understand their operating principles.

When using a blind rivet gun to fasten a rivet, a certain traction force is created.

In metal blanks that will subsequently be connected to each other, you need to drill a hole whose diameter is equal to the diameter of the rivet. After this, fix the rivet on the device, insert it into the hole and squeeze the tool handle.

During operation of the blind riveter, the rivet is expanded by a special ball, which, when the handle is pressed, enters the tube.

Thus, outer side The rivet is flattened, which allows you to firmly fix the parts being connected to each other.

A threaded riveter is also suitable for home work. manual type. Its operating principle is almost the same as that of the previous mechanism. The only difference is that in a threaded riveter the ball is retracted due to the fact that the cut thread rotates.

This type of connection is more optimal for thin-walled parts, where it is quite difficult to cut threads, but this type of connection is needed.

When a threaded manual riveter is used, it is possible to screw a screw or bolt into the rivet.

In most cases for home use They buy manual riveters; they are still more functional and versatile, and at the same time they cost a little less than threaded tools.

Different types of drive

The most common are manual riveters, but devices with various drives are also found. They are pneumatic, pneumohydraulic, and mechanical. Of course, each type has its own price. It also depends on the manufacturer - for more well-known brands, the price will be higher accordingly.

Pneumatic and pneumohydraulic tools are mainly used in production, since their design is more complex. At home, it is better to use manual riveters. When purchased with them, they come with removable heads, which allows you to use rivets of different diameters. Also, a head of the required size, as well as rivets for a manual riveter, can be purchased in a store without any problems.

Connecting parts with a tool

As mentioned above, the most popular in everyday life is a manual type riveter. Part of this device includes sleeve and rod. Now let’s figure out how a manual pull-type riveter works.

First, the sleeve is inserted into a pre-prepared hole, after which we take a rivet gun, which draws the rod into itself. All that remains is to press the handle of the tool and the sleeve will flatten, forming a strong and reliable fastener. All this will take very little time and effort.

This device has its advantages. Firstly, you can work with it even when only one side of the workpiece is free. Also, a manual riveter can be used even while suspended, without using other additional elements.

Of course, you should not forget about the quality of the rivet itself; the reliability of the fastening also depends on this.

Manual riveter: how to use

Using hand tools is easy and does not require any special skills. A properly purchased mechanism will do this job efficiently and quickly. The price when buying a tool should not play a big role, the main thing is to choose a model good quality. This will allow you not to worry about the tightness of the connection and the failure of the tool.

You just need to drill the holes correctly so that the diameter exactly matches the diameter of the rivet itself. We have already described the work of the riveter in detail above. After work, all that remains is to process the reverse flattened side of the rivet, that is, remove the resulting excess with pliers.

Manual riveter: reviews

The Stanley MR99 riveter earned very good reviews from the craftsmen. The pins do not get stuck and fly out without outside help. Of course, not the cheapest, but it is important that it works well.

The NOVUS J 60 riveter has also been in demand on the market for a long time, this is confirmed by numerous customer reviews. Works well, no problems. But it is suitable for one-time work, since large volumes get your hands tired. Its swivel head is very popular; it makes the tool even more convenient.

The Topex riveter has proven itself very well among consumers. It is inexpensive and suitable for one-time jobs. It is very convenient that the spout can be moved 90 degrees. This makes it possible to rivet in the most inconvenient places.

Also, the GESIPA NTS rivet gun received positive feedback from customers; the price is not cheap, but the German quality does not let us down.

How does a riveter work?

A construction worker or a person involved in the loading and unloading of large metal structures and materials, knows the answer to this.

And for all other people interested in the mechanism of operation of this tool, the explanation is given below.

The riveter is mechanical tool, which allows you to quickly and accurately fasten together sheets whose thickness is three millimeters.

With the same ease, it connects the profile and the corner to each other.

In order to carry out the riveting process, it is necessary to first do preparatory work.

Namely: drill a hole at the intended connection location.

In this case, both ends of this workpiece must protrude from the planes or parts being fastened. When the handle is pressed repeatedly, this part gradually flattens.

When its upper part is flattened as much as possible, the fastening on one side will already hold firmly, resting on the “thick” part.

After the riveting process is completed, the lower “tail” of the rivet part is bitten off with a special tool. You must always take into account the thickness of the parts being fastened. They need to choose the appropriate fastening size. For example, for metal sheets with thickness:

• Up to half a millimeter must be riveted with rivets with a size of 2.4 mm.
• Nine and a half centimeters – 3.2 mm.
• Twelve and a half millimeters - from 4 mm to 4.8 mm.

In this case, the hole for each different rivet must be drilled one millimeter larger than the diameter of the rivet. Accordingly, for a part with a width of 2.4 mm, a hole will be made two and a half millimeters thick, 3.2 mm - 3.3 mm, for 4 mm - 4.1 mm, for 4.8 mm - 4.9 mm .

The strength of a rivet of any size is determined not by its size, but by the quality of the metal, and the power of the resistance provided by the structural elements that were made with the help of rivets. If such pressure is high, the metal rivet gradually softens or deforms.

The operation of the tool is based on the flattening effect due to targeted pressure on a certain part of the piece (workpiece).

Rivets and working with them

An explanation of how a manual riveter works cannot be complete without considering the types of riveting tools (consumables - rivets).

There are two fundamental types of these parts: monolithic, that is, solid, and tubular.

The latter are usually called pistons.

All-metal rivets are more like just a piece of thick wire and are used only for manual view rivets.

Much later than the beginning of the use of the described one, the now more commonly used pistons appeared - the second type (inside there is soft metal that is quite easily flattened when pressed).

Most importantly, these parts are divided into two more subtypes: nut and pull-out. The latter contain two parts: a tube and an interior, the so-called poisson or rod.

From above like this simple design there is an enlarged part - the cap, which prevents the rivet from prematurely protruding or breaking. Poisson is introduced with reverse side, that is, from the opposite side - where the cap is located.

It turns out that rivets are inserted on both sides, subsequently flattened.

How does a riveter for threaded rivets work?

The principle is the same, but the peculiarity of the rivet material is that, after being screwed (hammered) into the structure, it is bitten off with a special construction tool.

And besides, you can choose any length this way.

If it comes to large volumes of rivets, you need to take the so-called professional mechanism, which allows you to make a larger number of rivets, while applying less effort.

A slightly more complex mechanism (besides the manual one) is called a pneumatic riveter. It works using compressed air.

Pneumatic devices require the use of a compressor. There are professional mechanisms that contain a hydraulic press in their design.

This type of riveter is called pneumohydraulic. As can be seen from the definition, it works thanks to two types of mechanisms that drive the main working element.

To select a tool for making a clear rivet joint between metal parts, including sheet metal and profiles, you need to take into account the thickness of the material being fastened.

More details about the pneumohydraulic riveter are presented in the video:

A manual riveter is a tool designed for fastening sheet materials. Most often, sheets of metal up to 3 mm thick are fastened with rivets, but you can attach a sheet of metal to a profile or corner. We have a pull-out riveter, the principle of its operation is slightly different than riveting with conventional rivets and a hammer. In this article we will look at the main types of hand tools for riveting, how to select rivets and how to use this device.

How to work with a blind riveter

First of all, you need to drill a hole through both sheets to be fastened, right through. The diameter of the hole should be the same as the diameter of the rivets. Then we “charge” the rivet and insert it through both sheets and begin to squeeze the handle (more than one squeeze will be needed). The rivet begins to flatten when the ball is completely retracted into the rivet - the tail of the rivet is bitten off. As a result, we have 2 sheets of metal riveted on both sides. In the photo below you can see the instructions in pictures.

Video - how to rivet correctly

My partner and I made a video for you on how to use a riveter. I hope it will help you understand how and what to do.

What types of riveters are there:

Regular inexpensive model

Take, for example, the cheapest option from Stayer - the very first photo. Its cost is 300 rubles. It supports all rivet diameters (2.4 mm, 3.2, 4 and 4.8 mm), so you can select the most suitable rivet diameter for the materials being fastened.

For example, thin rivets with a diameter of 2.4 mm are intended for fastening sheet material total thickness up to 5 mm. Of course, there is also such a parameter for blind rivets as length. The longer the rivet, the thicker the material that can be fastened.

I bring to your attention a table of the relationship between the size of the rivets and the thickness of the material.

Riveters with a rotating “head”

It differs from the usual one in that the “head” of the riveter can be rotated 360 degrees. This is very helpful when working in hard-to-reach places, where ordinary people cannot reach. True, it costs more, about 350 rubles. We are also considering the Steyer model.

Reinforced models (two-handed)

For people who work as riveters all the time, they produce power versions.

They differ from ordinary ones in that they squeeze it with both hands, which saves significant effort. Imagine that you need to rivet 500 rivets. It will be difficult to complete such a volume of work with a regular riveter, but with a reinforced one you can rivet everything much faster and without strain. What the reinforced one looks like is in the photo below.

Professional models with extended service life

In addition to household models for home work, there are also professional ones on sale. They differ from household ones in better quality and longer service life. For example, a model from Kraftool. A regular, non-rotating model, but costs significantly more. In the photo below, the Kraftul riveter - price 400 rubles.

All riveters in included 4 interchangeable fittings for different rivet diameters. They are changed using a special key, which is also included in the kit.

Rivets are usually sold in small packages of 50 pieces. Rivets vary in diameter and length; the thicker and longer the rivet, the more expensive the packaging. For example:

• 3.2*6 mm - price 26 rubles
• 4*12 - cost 35 rubles
• 4.8*16 - 50 rubles

When purchasing consumables, do not forget that rivets are needed for the rivet maker, pull rivets. Otherwise, stores also sell regular ones that are riveted with a hammer.

Riveting parts is a very popular method used today in construction, production and everyday life. It is used to install such fasteners in metal elements. This is a simple tool, the working head of which has a holder into which a fastening element is inserted. A hole is drilled in the workpieces where the rivet is placed, and when the tool lever is pressed, it is flattened, securing it in the material. Everything is very simple! Someone will say why use this method if there are others for connecting metal elements, for example, welding or fastening with self-tapping screws. But they are not applicable in all cases. Here are some examples.

• It is necessary to connect metal parts without changing their structure.
• Do not heat metal or surfaces located next to the elements being connected.
• It is necessary to connect the parts from different materials, for which welding is not applicable.
• It is necessary to fasten hard-to-reach structural elements, and the impact of the tool is possible only from one side.
• There is a possibility of a fatigue crack appearing from part to part when they are connected.

Then they use a riveter, which helps solve all these problems. What else is good about this tool? Let's figure it out.

Advantages of joining parts with rivets

This type of fastener has been used since time immemorial; for example, it can be found in military armor. By the way, during construction Eiffel Tower and the cruiser Aurora, rivets were also used, only much larger in size compared to fasteners in armor. Now such elements are used in construction, for example, when installing fences, installing frames of ventilated facades, attaching steel sheets to a profile; in production when connecting metal parts of units, machines, boiler equipment; in everyday life when carrying out repair work. Not surprising, because the riveter has so many advantages!

The tool is easy to work with

Installing rivets is a fairly simple method of joining parts compared to, for example, welding and is much safer. You just need to select a rivet of a suitable diameter and install it in the drilled hole. To get the hang of it, you only need to install a few elements!

The result is a reliable and aesthetic fastening

For example, you need to connect metal and wooden blanks. The riveter will cope with this task, and the connection will be very reliable. A rivet installed in a drilled hole firmly fixes the parts, does not deform them and does not allow fatigue cracks to propagate. The fastener rod is bitten off, and with front side the details remain a neat hat, which looks very aesthetically pleasing and does not spoil appearance products.

Minimum costs for tools and fasteners

The cost of a riveter is much lower than, for example, a welding machine. An amateur model can be purchased for up to 1000 rubles, a professional one will cost more, but will help achieve higher productivity. Concerning Supplies, the price of rivets is low. For example, a package of 50 pieces costs about 40 rubles . For comparison, when installing a frame for a ventilated facade per 1 sq. m there are about 20 rivets - you will spend less than 20 rubles on this. And if you take a package of 1000 pieces, the fasteners will cost even less. In construction and manufacturing environments where rivets have to be used large quantities, this option will be very profitable.

As you can see, rivet connections are optimal method when you need to connect metal elements, spending a minimum of money and effort. If you decide that your work requires a riveter, do not rush to buy the first model that you like. There are several types of tools: some are used in private construction, others are designed for intensive loads in production. Let's talk about each in more detail.

Types of riveters

The division of a tool occurs not only according to the “household/professional” principle, but primarily according to how it is designed. There are two main parameters by which classification is carried out.

By food type

• Manual- the simplest devices that are affordable, moreover, they can be used in any conditions: when high humidity and dustiness, at heights, when there is no power supply, etc. Two-handed riveters have two handles, which are compressed with both hands to transfer force to the working head - this is necessary for deforming the rivet. This tool is designed on the lever principle, so work productivity directly depends on the effort exerted by the user. For a comfortable grip, there are rubber pads on the handles, as well as indentations for the fingers. The most versatile tools are those with a rotating head: they are suitable for working in hard-to-reach places. Models rocker type They have one handle and a scissor mechanism through which force is transmitted to the working head - to do this you need to press hard on the handle. This design is very convenient if you need to install a lot of fasteners. Most often, manual riveters are used in private construction, as well as installation teams and in small workshops where the process of installing rivets is auxiliary.
• Rechargeable- externally they look like a pistol and have a built-in battery that generates energy for the impact required when installing rivets. Therefore, the user makes less effort when working compared to a conventional riveter - you only need to press a button. Even during prolonged work, the load on your hands is not felt. Depending on the battery capacity, its charge is enough to install from several hundred to several thousand fasteners. Like all hand tools, such models are used in facilities where there is no power supply, but, like any cordless tool, it is not designed to work in conditions of high humidity and dust. This is an excellent option for use in a workshop or for installation work.
• - the most productive type of device, since the energy for installing the rivet comes from a source of compressed air - a compressor. But the design of such a tool is also more complex: in addition to the gun itself with a trigger and a working head, it contains a cylinder for compressed air and a pusher. To operate, the tool must be connected to the compressor via a hose. It is important to remember that pneumatic riveters must match the operating parameters of the compressed air source. Operating pressure and the air flow of the tool must not exceed the corresponding compressor parameters. As a rule, such models are used in production sector when, when assembling products, the installation of rivets is the main work process and occurs almost continuously. In this case, a manual model will not be suitable due to low productivity, and a battery model will not be suitable due to limited battery charge.

By type of fastener used

• For blind rivets- the most common type of instrument. A pulling force is exerted on the fastener when the tool handles are pulled together or the trigger is pulled. As a result, a riveted head is formed at the base of the element, holding it in the workpiece. The remaining rod from the rivet is discarded.
• For threaded rivets- models that are used primarily in industry. Installation of the fastener occurs by flattening it in the prepared hole, while the fastener is screwed onto the holder. The rivet itself is hollow inside and has an internal thread - thus, the hole in the metal is strengthened due to it, and it is the basis for screwing in bolts and screws.

Choose based on your own goals suitable tool. For example, if you are planning to build a fence at your dacha, you will attach the corrugated sheet to the pipes. Take a manual blind rivet gun that has two handles. If you are looking for a tool for daily work, for example, in the manufacture of ventilated facades, choose either a manual rocker-type model or a battery-powered one - it all depends on the operating conditions and the scope of work. To equip a production department or workshop, the right decision would be to purchase a pneumatic riveter, with which labor productivity will be much higher.

Pay attention to what determines the functionality of the tool and productivity. Knowing the basic characteristics will help you make successful purchase- you will select the model that best suits your needs and specific work.

Important selection options

The main characteristic is the thickness of the workpieces being fastened. Decide which metal sheets or profile you will connect - their total thickness should not exceed the permissible value of the riveter. For example, for the model it is 8.5 mm. The next parameter is the size of the rivets used. For example, the tool has 4 interchangeable attachments for working with fasteners measuring 2.4 - 4.8 mm, and 5 attachments for fasteners measuring 3.2 - 6.4 mm. These models are suitable for a wide range of jobs. If you plan to do one specific operation, which requires a certain size of fasteners, does not need so much functional model. Don't forget about the tool kit. Many manufacturers include not only replacement attachments, but also maintenance keys. The pneumatic riveter has replaceable jaws and a container for used materials, which ensures safe work - the rods fly off into the container and not towards the operator. The model comes with a case and a set of rivets to get started.

Don't have a riveter in your arsenal yet? Then it's time to buy it! Once you try it out, you will see that it is very easy to make reliable riveted connections.

Place your order now - you will receive the product as soon as possible with delivery or you can pick it up at the nearest pickup point.

This very specific tool has a number of other names - “river gun”, “rivet gun”. Manual riveters are purchased mainly for household needs, as they are simpler and cheaper items compared to their “brothers”. However, their range is quite impressive, and the cost of individual products differs significantly - from one and a half hundred rubles to 2 - 3 thousand. Which riveter is better to buy?

The main rule when choosing any “device” is what is it for? It's clear that manual models inferior to professional ones in both versatility and performance. In other words, you need to clearly define the tasks that will have to be solved.

By the way, if you have to work frequently and use rivets of different sizes, then it is advisable to have at least 2 products in your house that are different in “parameters”. For example – one-handed model + two-handed. But if the business is on stream, it is better not to waste money on cheap products. In any case, the riveter completely pays for itself, just like...

What to focus on

Rivet material

If it is aluminum, then it is easy to work with, so it does not matter which “riveter” you choose. It is more difficult with steel, so the device should be selected more powerful.

Ease of use

Firstly, the instrument can be one- or two-handed. Naturally, the latter can create greater pressure, so it allows you to work with fasteners made of any material, different sizes. Although in some cases (for example, limited space) you can only use one-handed.

Secondly, the head design. If it is rotatable, then this creates additional convenience. Sometimes you have to rivet in difficult areas (in “inconvenient” places), and this feature of the tool is very helpful.

Thirdly, are there replacement attachments for fasteners? various sizes? There is no need to comment on this.

Adaptations

Some models have a special “container” where “waste” is dumped. For example, when you have to rivet a roof or build a fence from corrugated sheets, small pieces of metal scatter to the sides. If they find themselves in the grass (sand, on the ground) around the place of work, then problems cannot be avoided, especially with children - they like to run around barefoot in the summer.

Some “home craftsmen” prefer not to think twice about which tool to purchase. If the amount of work is insignificant, buy a couple of cheap models at once. If one breaks, there is always a spare at hand. And 150-200 rubles is not that much money to go around and ask the price. Although this point of view does not suit everyone, it also has a right to exist.

There is another opinion. It’s better to buy a professional model for 700 rubles, and this will guarantee that it will last long enough. Moreover, perhaps the riveter will be needed more than once.

It is also necessary to take into account such a factor as the owner’s accuracy. We do not claim to be the author of the thought, but, nevertheless, let’s say that anything can be broken, no matter how much “it” costs. Therefore, you should not trust too much people’s reviews about a particular model, especially strangers.

Considering the above, one should not be surprised at the opinion of professionals that choosing a manual “riveter” is akin to a lottery - you cannot guess whether you will be lucky or not.

Many have seen this device in stores selling tools, but not everyone knows how to use it. Those who have never held a blind riveter in their hands simply will not be able to appreciate the convenience and versatility of its use.

Rivet connections have been and remain universal and in an inexpensive way splicing of various parts. In shipbuilding and aircraft construction, this is generally the only way to attach the skin to the frame.

A classic riveting looks like this:

This is exactly how they riveted the hull of the Titanic and the handle to your frying pan.

IMPORTANT! The rivet connection is non-separable. To separate the parts it is necessary mechanically break (drill, cut) the rivet.

Modern technologies have also touched upon this ancient method. In everyday life, few people use a hammer and a crimping attachment. There are semi-automatic tools that allow you to rivet parts to each other almost with one hand. True, the rivets look a little different.

How does a manual riveter work?

To understand the process, you need to see the rivet in action. The diagram shows its main elements:

The rivet sleeve is placed in the prepared hole. The tool is put on the core and rests against the shoulder of the rivet. The fixed rod is pulled out of the sleeve, riveting its upper part.

When riveting is completed and the head of the core is firmly seated in the riveted sleeve, the core comes off. The riveted materials are connected only by a sleeve.

IMPORTANT! The material describes a mechanical riveter. There are hydraulic, pneumatic and electric devices. However, they are not used in everyday life.

We will also consider the operating principle of the tool itself and its structure in the diagram.

• the head (1) is put on the core of the rivet installed in the hole;
• the body (2) performs the functions of the lower handle and thrust frame;
• the upper handle (3), resting on the frame with the help of an axis (9), is a power lever;
• when the handles are compressed, the working sleeve (4) compresses the collet jaws (5), tightly fixing the rivet rod;
• continuing to move, the collet mechanism pulls the rod out of the rivet sleeve, forming a riveted ring;
• when opening the handles, the conical bushing (6) under the action of the spring (7) opens the cams, allowing the collet mechanism to take its original lower position;
• the cover (8) is a stop for the spring and is removed to service the collet mechanism;
• for the convenience of the operator, replaceable heads (10) are stored in the housing, for various diameters rivets
