Machine for flexible wire scope. Wire bending: manually and on wire bending machines

Machines for flat wire bending are widely used by manufacturers of commercial equipment. The wire is fed from the coil, passes through the correct block and is fed to the bending console, where the product is bent according to the specified CNC program. At the end of the bending process, the part is cut off by a guillotine. All operations are performed fully automatically. The machines have ample opportunities for the manufacture of flat products of any complexity: rings, frames, various open and closed contours, flat spirals. In order to obtain a 3D product, many customers use a press, thus having a high productivity in the production of flat products on a wire bending machine, the workpiece is placed under a 3D bending press, which ensures high productivity and good repeatability of the resulting wire product.


have a patented non-flatness compensation system. Actual for domestic wire, which, when unwinding from a coil, has internal stresses, the geometry of the product "twirls" and it turns out to be not flat (which is usually compensated in 3D machines by turning the console). UME bending machines have the mechanical ability to adjust the "reverse twist" of the wire, resulting in a completely flat product, without adjusting the bending tool or CNC program.


UME series wire bending machines have a turntable so that the operator can adjust the table to a comfortable angle (eg more vertical or more horizontal) according to the product geometry.


UME series wire bending machines very easy to operate and reliable. The CNC of the well-known company B&R (England) allows you to program bending modes, it is possible to program a batch of products, where several products are sequentially performed one after another. Both bending by rolling and pushing are programmed, with the transition from radius to radius.

Wire bending, performed both manually and with the help of various tools and special equipment, allows you to give products from this material a different configuration. During the bending process, the inner layer of the wire is subjected to compression, and the outer layer is stretched. Wire bending machines, which today are presented in a wide variety of models, are very popular, as bent wire products are actively used to solve various industrial and household tasks.

The simplest wire bender

In order to perform bending operations at home without any problems, it is best to choose a wire made of soft materials. It is possible to carry out simple bending of a stiffer wire, if necessary, using conventional plumbing tools:

  • pliers (using such a tool that every home craftsman has, you can form a simple bend in the wire, as well as securely fix its segment for further processing);
  • pliers (using this tool, which is one of the varieties of pliers, you can perform bending of varying degrees of complexity);
  • wire cutters, or needle nose pliers (using such a tool, the wire can be cut into segments of the required length).

Simple tricks for manual wire bending

If it is necessary to make a product of complex configuration from wire using the bending method, it is better to first draw it on paper and periodically check with the sketch. To form the simplest figures, such a sketch can not be used. For example, if you need to create a bent product of a rectangular shape, you can do this as follows:

  • The wire in the place of its future bend is clamped in a bench vise.
  • The upper (not clamped) part of the wire is bent with ordinary pliers or a hammer.

As a result of such a simple procedure, a bend at a right angle is formed on the surface of the wire.


For the manufacture of a large number of the same type of wire parts, templates and home-made fixtures are used.

Manual bending rules

If you are going to manually bend the wire, you must adhere to a number of recommendations that will allow you to perform such a procedure without harm to your own health.

  1. All bending procedures should be carried out only with gloves made of dense fabric.
  2. The wire that is being bent must be secured in a vise as securely as possible so that it does not jump out during operation.
  3. All tools and equipment that you are going to use for work must be in good working order and perform the functions assigned to them with high quality.
  4. Heavy tools and fixtures that you use when bending should not be placed on the edge of the desktop, so as not to accidentally hit them and drop them on your feet.
  5. Carrying out all the manipulations with the wire bending tool with one hand, the other should be kept as far as possible from the place of the future bend. Pliers and any other tool can break off and injure a hand close to the bending site.

It is possible to perform wire bending using improvised means only in small volumes, since such a procedure is quite laborious. In addition, this operation can only be used to create products of the simplest configuration.

To manufacture various products in large volumes, including those with complex shapes, allows a specialized machine for bending wire.

Working with wire bending machine

For the manufacture of a large number of bent products from wire, various methods can be used, for the implementation of each of which special equipment is used. The most common and economical is the bay bending method.

Bending according to this technology takes place in several stages.

  1. The wire, which is wound on coils, is fed to a two-plane roller machine that aligns it.
  2. After alignment, the wire is fed to the wire bending machine, on which the product of the required configuration is formed.
  3. The formed product is cut off, and the entire bending cycle is repeated anew.

The use of this technology allows you to fully automate the bending process and thus achieve its high productivity.


Budget wire bending machine

A wire bending machine can also look like a fixed template, around which the wire is rolled using movable pressure rollers. Using such devices, it is possible to form bends of even the smallest radius on the surface of the wire, the value of which is comparable to the outer diameter of the workpiece. In this case, the configuration of the product formed on such a machine can be quite complex.


Adjustable stops and variable levers of this template allow you to create many combinations of wire bends

The wire bending machine can also work on the principle of pushing the workpiece through a system of rollers. When using such equipment, the end of the wire is connected to a special wire, which pulls the product through the working bodies of the machine. A wire bending machine of this type, due to the peculiarities of its design, makes it possible to manufacture products that differ even in very complex shapes.

When aligning the wire, a wire bending machine is also used, which in this case is used for straightening. The correct frames or two-plane correct blocks can act as working bodies of such equipment. At the same time, rotating regular frames are distinguished by higher efficiency, which is why they are used in cases where the alignment of the wire surface must be performed as smoothly and efficiently as possible.

Types of professional equipment

The simplest type of professional equipment used for wire bending are machines with one console. Meanwhile, on such devices it is possible to produce only products of a simple geometric shape, the development length of which does not exceed 1000 mm.

More complex products with a development length of more than 1000 mm make it possible to create two-cantilever equipment, on which the workpiece is deformed simultaneously from both ends. On such a machine, you can make products with many complex bends.

The most complex wire products allow you to create 3D machines on which bending can be performed simultaneously in three dimensions. The machines of this category are endowed with such unique functions by a rotary bending console, all movements of which are controlled by an electronic automated system. Despite all the advantages of processing on such equipment, it is quite expensive, so these machines are used in exceptional cases.

Varieties of machines for bending wire

Wire bending is one of the ways to give it a new shape using manual or mechanical action using special equipment.

The bending itself is due to the compression of the inner layer, whereby the outer layer can be stretched and folded. Such technological works are in great demand, as well as equipment for manual bending.

You can create products from bent wire with your own hands.

In this case, it is desirable to choose softer plastic materials for the process, so that the wire can easily bend, and do-it-yourself work does not create difficulties.

If the wire is rigid and has a large diameter, then for its manual processing it is necessary to use certain tools:

  • using pliers, you can create a slight bend of a few mm, it is also convenient to fix the material with them for further processing;
  • you can cut the wire into separate parts with wire cutters or needle-nosed pliers;
  • pliers (a kind of pliers) are considered one of the most convenient and versatile tools for bending wire with your own hands.

Before you start manually bending the material for the rings, it is better to create a certain template on paper and periodically check it during work. Simple shapes can be made without the participation of templates.

For example, to create a conventional rectangular clamp, it is enough to first clamp a part of the wire with a metal vise, and bend at a right angle on the remaining piece with pliers or a hammer.

Rules for manual bending

When doing manual work on bending wire with your own hands, you should follow certain safety rules that can protect your hands from possible injuries:

  • Before starting work, it is advisable to put on gloves made of thick dense fabric;
  • Materials should be well secured so that they do not jump out of the vise during their bending;
  • All machines and tools for manual work must be in good working order;
  • Do not put heavy objects on the edge of the table (for example, hitting pliers, you can drop them on your leg and get a noticeable bruise, or even injury to your fingers);
  • When working with wire with one hand, try to keep the other away from the bend (pliers can break off and injure your hand).

Safety rules will protect your hands, but the DIY bending process itself is still quite complicated and time consuming. You can bend products manually only if you have certain experience and knowledge.

Special equipment helps to bend the wire in large volumes. Let's study it in more detail.

Processing methods

If we talk about bending wire on a large scale (in production or a specialized plant), then various methods are used for its plastic deformation.

One of the most common and economical is the bay method of processing.

In this case, wire rings are wound on coils, and then they are fed to two-plane roller machines that align the wire.

After that, the material is processed on bending equipment (the necessary shape is created), at the end the wire is cut off, and the whole cycle of work is repeated again.

At the same time, all work is fully automated, which allows you to save time and money and use the device to create a simple curved structure with a sweep length of about 1000 mm.

For do-it-yourself wire-running, there are special devices that consist of fixed templates of certain curvature radii (the radius can be either one or several).

The material is rolled around the created template using pressure rollers.

Basically, this technology is used to create bent products that have a small bend radius (about the same as the diameter of the wire).

The method of pushing the wire is similar to the way the 3-roll equipment works on a roll forming and spring winding machine.

The material is pushed into the device with the help of a special wire, then it is pressed against various rollers, in connection with which it is possible to change the parameters of the bends and make transitions to different radii.

This device allows you to bend various structures with a complex configuration and large bending radii on the reamer - from 1000 mm or more.

You can align the wire using straightening equipment or a special device. This equipment includes units consisting of rotating straightening frames or two-plane straightening blocks.

In this case, rotating frames are preferable, as they allow you to align the material more smoothly.

professional equipment

If only the simplest devices (vice, pliers) are used for bending wire on their own, then professional machines are put into action for mass industrial processing of the material (for example, for the production of key rings, or springs for handles).

A wire bending machine with one bending console is one of the simplest and makes it possible to create bent products of a simple shape. The length of the reamer in this case should not exceed 1000 mm.

Two-console machines can work with a reaming length of more than 1000 mm.

The material is cut into the required pieces, then it is deformed from both ends simultaneously.

Such equipment allows you to create products with a large number of bends. Machines with only one console can no longer perform this work.

Also on double-console machines, you can make figures with closed bends.

Wire bending on so-called 3D machines is becoming more and more popular these days.

It is possible to make volumetric spatial bending using a rotary bending console, which is controlled by an automated system.

Unfortunately, such processing of the material is quite expensive, so basically the parts are created using simple flat bending, and then, if necessary, automatic welding of individual parts is carried out.

But due to welding seams, products become more fragile and short-lived, so their cost is relatively budgetary.

Handicraft and industrial wire bending methods

It is difficult to say where wire products, which are a metal thread or a thin rod, have not been used today. Wire bending made it possible to give products any desired shape. Both with the help of both hand tools and mechanical influences on special equipment.

From a physical point of view, the process of bending a wire consists in the simultaneous compression of the inner and stretching of the outer layers of the metal of the wire. The process can also be accompanied by a longitudinal displacement of these layers, if twisting occurs. This technology of working with metal wire is widely used both in many industries and in jewelry.

Metal wire bending methods

There are several main ways to give the metal wire the necessary shape of the finished product, so we can distinguish:

  • manual way of bending the wire using special tools and simple fixtures. It is used for wire with a diameter of up to 3 mm in the manufacture of simple products in ancillary production or household. As a rule, it does not require practically any financial investment and special knowledge;
  • manual way of making jewelry from wire up to 2 mm in diameter. Requires special tools and fixtures, as well as certain knowledge and skills to work with precious metals;
  • bending wire from a coil, which is based on a special device called an unwinder;
  • bending a wire from a metal bar;
  • bending by wire rolling;
  • bending metal wire by pushing.

Wire bending machines

Mechanical machines for the mass production of parts and finished products from metal wire are widely used in industrial production. Depending on the method of technology for shaping the finished product, there are:

CNC machines

The development of machine tools has made it possible to produce wire bending machines with one or two bending consoles. They can produce finished products not only in flat 2D shapes, but also in spatial 3D models. The transfer of control of production processes to an industrial computer made it possible for the CNC machine tool to ensure the rotation of bending consoles in three-dimensional space in any given sequence.

Wire bending by CNC machines not only allows for higher productivity, but also for the production of products of different shapes just by changing the production program.

Do-it-yourself wire bending devices

In any household, metal wire is widely used, or rather, various products made from it.

Bending a wire with the help of a manual metalwork tool with your own hands allows you to produce a fairly large number of products necessary for the household, such as:

  • clamps,
  • brackets,
  • hangers, etc.

But for this you have to use the softest and most ductile types of wire, so that you can easily bend the metal into the shape we need.

So, for working with wire up to 3 mm in diameter, round-nose pliers, pliers and a bench vise are suitable, and you can cut the wire with wire cutters or side cutters. Such a set is quite enough to give the metal wire the desired shape and its subsequent processing.

Working with large diameter wire has certain difficulties. But if it is also rigid, then to bend it manually you will need to use special bending devices.

Of course, you can buy a ready-made bending device, but it is quite possible to make a tool with your own hands. How to make a do-it-yourself device for bending wire from available parts can be seen in the photo.

How to bend the wire into a ring exactly

In order to bend the wire into a ring and at the same time it turns out to be of the correct shape, you must either use a pre-made wooden blank of the desired diameter, or use a piece of metal pipe of a suitable diameter. We wind at least two turns on the template and make marks, while not forgetting to take an amendment for the thickness of the cut. Next, cut the wire and weld an even ring.

Types and principle of operation of wire bending machines


There are several ways to bend the wire. The most common option is to bend such parts manually. Within the framework of industrial production, the manual method is not cost-effective and has numerous costs. In production, various types of wire bending machines are used.

Types of wire bending machines

Depending on the technology, several types of wire machines are distinguished:

  • manufacturing parts from the bay;
  • bending from a metal bar;
  • bending in a rolling way;
  • bending by pushing;
  • cnc machines.

Wire making machines

The specified type of unit is used for serial production. Such wire bending machines have high productivity and cost-effectiveness compared to others.

The wire manufacturing process goes through several stages:

  • an unwinder is taken;
  • a bay with wire is fixed in it;
  • two mechanisms act on the wire at once, one of which is planar, the other is roller;
  • the wire becomes a straight rod;
  • a straight wire rod is placed in the bending section of the apparatus;
  • the output is a part that has the desired shape;
  • the finished product is cut off with special mechanical scissors.

Such a bending machine is able to produce only a certain type of finished product. This is due to the presence in it of devices that are pre-configured for the manufacture of parts having a certain shape.

Units produce parts that are simple in shape and do not offer a wide variety of them. The number of bending operations on such machines is limited to five.

Machines for bending metal wire

This device is considered more technologically advanced than the previous one. The machine carries out additional processing of the finished product, which the unit does not do from the bay.

The device allows you to make stamping and carving on wire products.

This type of machine has two main disadvantages:

  • differs in low productivity;
  • requires the installation of an auxiliary workpiece feeder, which is characterized by a complex design.

Roll bending devices

Devices of this type are designed for the manufacture of round parts. The wire feed on the machine is carried out on a shaft with a predetermined radius. Feeding is carried out using guide rollers. A rotational movement of the shaft is created, resulting in the wire wrapping around the finger several times.

The device allows you to adjust the spring step and the angle of bending of the part. This is ensured by the position of the running rollers relative to the shaft.

This manual bending machine only makes one type of product. In order to change the type and shape of the manufactured products, a preliminary replacement of bending devices will be required. It will be necessary to perform commissioning work.

Push-pull units

The pushing method is used for wire that needs to be shaped into a complex geometric shape.

The pushing procedure is based on the translational movement of the metal material through the roll forming machine. The given shape of the part is given by rolling rollers. Instead of the roll forming device of the machine, a spring winding device can be used.

Equipment that can bend wire in this way is complex and requires special knowledge.

Machines with numerical control

Progress in machine tool building made it possible to introduce CNC units, with the help of which wire bending became possible.

The machines produce 2D parts and 3D spatial products. The machines are controlled by an industrial computer. Thanks to the computer, it is possible to rotate the bending consoles in three-dimensional space in any sequence.

CNC units have high labor productivity. If it is necessary to change the form and type of products, it is enough just to change the production program on the computer.

Do-it-yourself options for bending wire materials

For bending, sometimes it is enough to use improvised tools. Much depends on the thickness of the material used.

For bending products with your own hands, having a diameter of up to 3 mm, suitable:

  • metalwork vice;
  • pliers;
  • pliers.

The material is cut with side cutters or ordinary wire cutters.

Products with a large diameter will require the use of a do-it-yourself device. The assembly of the machine is carried out in stages:

  1. a corner made of steel 19 cm long is bolted to the table;
  2. a frame is made of a metal plate, holes are drilled in it;
  3. a frame with guide rollers and handles is screwed to the corner;
  4. a metal bar is selected to the bed groove;
  5. several through and blind holes are made in the bar;
  6. a handle and a corrugated roller are bolted to the bar;
  7. plates are welded at the bottom of the bed;
  8. the bar is inserted into the bed groove so that it slides in it, and does not fall out;
  9. guide rollers are screwed;
  10. the construction of the bar is screwed to the corner.

A hand-made mechanism will allow you to make products of a more complex configuration.

Wire bending, performed both manually and with the help of various tools and special equipment, allows you to give products from this material a different configuration. During the bending process, the inner layer of the wire is subjected to compression, and the outer layer is stretched.
