Tools for cold forging with your own hands

Making machines for cold forging with your own hands

Forged metal products are a popular decorative element that attracts beauty and sophistication. Making such parts requires a large financial investment, and not everyone can afford such an option. There is a way out. the use of cold forging, which can be done independently, but you need to build a machine tool.

Cold forging. a popular type of work, due to the fact that with its help you can create unusual details of different shapes and sizes.

Using a machine for cold forging, you can make a fence for a flowerbed, a decorative lantern, an unusual fence, railing or handles for benches and other elements. You can see what the parts created through this process look like in the photo.

The advantage of cold forging is also that it is quite easy to make a machine with which you can create such parts with your own hands. It will help to save on the purchase of expensive equipment.

The process of cold forging consists of three main elements: bending, pressing and welding parts. The equipment required for this process is quite simple and compact, you can make it with your own hands and it will not take up much space in your workshop or garage.

With cold forging you can start learning how to process metal, t.к. The process is easier and safer because you do not have to deal with high temperatures as with other welding processes.

For this process usually use a ready-made template. that is, blanks of parts.

Of course, cold forging has its own subtleties, consisting mainly in the fact that the detail in the process is easily damaged or deformed: forged elements often break, and the flaw can not be corrected, so do forging must be very carefully.

However, using a quality machine and a drawing of the future part, you can easily learn to create products of twisted, wavy and other unusual shapes. The options you can see in the photo above.

The process of processing workpieces through cold forging takes place in several steps. The first thing is to create a template or drawing of the future structure.

You need to calculate the dimensions of the product, in order to, firstly, buy the right amount of material, and, secondly, in order to properly set up the machine.

Different machines give different possibilities to create patterns. it depends on the complexity of making the tool.

For example, the simplest machines made by our own hands can only bend products, while with more complex models it is possible to create patterns, etc.

After the template or drawing is ready, you need to buy the necessary amount of material according to your calculation. For cold forging you will need iron rods, you can buy them in a store.

The rods for cold forging should not be too thick, otherwise they will be difficult to bend. The next step is to make the parts with your own hands.

The most important thing here is to set the settings correctly, so that when the machine does not damage or deform parts, i.e.к. It will not be possible to correct the problem.

The last step is fixing the made parts on the frame. This is done by welding.

Especially careful when welding with your own hands need to be with thin-walled tubes, t.к. they are easy to burn through, and then the construction will be defective and you will have to do it all over again.

You can watch the entire forging process on video before you start working on your parts.

But before you start cold forging, of course, you need to make a machine tool, which is necessary for this. Machine tool “Snail” the most common apparatus for processing metal products by cold forging their own hands.

You can see all the steps to create a machine tool in the video. there is nothing complicated about it, and almost everyone will be able to cope with this job by themselves.

  • You do not need to build a forge with all its equipment (forge, anvil, and so on).
  • The possibility of automation, which reduces the labor intensity of the manufacturing process.
  • The use of cold forging enables a significant increase in productivity, because according to a given pattern it is possible to make products in batches, i.e. to establish mass production. It is convenient when decorating large areas (surfaces). For example, fences, the same bars on the windows of the building, staircase railings, garden arbors, and much more. This method of working with metals is also well suited for interior design. lattices for fireplaces, a variety of supports for pots, legs for furniture. There are many variations.
  • The equipment can be installed in any room.
  • Plasticity of metals decreases, the internal structure is not violated by exposure to high temperatures, which increases the strength of products. And this means a longer service life.
  • Cold forging makes it possible to produce the so-called aging of blanks, which allows you to do the styling of “antique.
  • As a consequence, the reduction of total cost and production cost.

All the “elements” of any design (ornament) made in this way are connected to each other, usually by welding. Sometimes. twisting, rolling.

What equipment do you need to have

It is clear that in the process of work different tools and devices will be needed. Many of these every good owner already has (pliers, hammers and so on). But you will also need a variety of special devices. You can buy a ready-made set for cold forging, so to speak, for all cases.

Welding machine

If the “amateur cold forge specialist” is not a professional welder, it is better to buy an electric model. Detailed recommendations on the choice can be found on the Internet, so just one tip. It is better if the “welder” will work from both DC and AC voltage. It is convenient, since you can not guess in advance what parts you will have to deal with. For example, reversing the polarity (from “” to “-“) will allow you to join quite thin metals without fear of burning them.

(welding transformer). Not much else is needed for domestic use.

angle grinder (angle grinder)

It is clear that the workpieces will have to be cut, and welding seam and the ends. to grind. It’s the same here. there’s no point in saving money. The machine must be powerful enough (and high-speed) to be able to handle any part.

For a good model (for example, Makita, Hitachi) will have to spend in the range of 2,500. 3,000.

A deburring machine

You will need it, if you will have to level a weld in a hard-to-reach place. For example, in the corner. In the manufacture of various openwork designs such “points” will be quite a lot.

Or a good electric drill. Often you can’t do without metal drilling. Reverse rotation is a must.

Tool kit

    Template. Used for bending in a curve or in a circle.

  • Scope. An indispensable thing if you need to get some kind of “pattern”.
  • “Lantern”. Allows making a three-dimensional construction of a whimsical configuration from 2 to 4 parts (strips, rods) welded together.
  • “Bending”. For bending workpieces at the required angle (also on the arc). In addition, there is another option. a simplified bending machine. Enables operation with workpieces up to 14 mm in cross-section. Read more about these machines here.
  • “Snail”. It is used to make various “curls.
  • “Twister”, Provides twisting of the material along the longitudinal axis.
  • “Wave”. This attachment makes it possible to make a sequence of single-type patterns with changing geometry.

Depending on the manufacturer and equipment

Approximate for individual items (in rubles):

You can also buy a special bending machine. It is equipped with everything necessary for the production of all expected types of work with metals. The lineup is quite large, but also by the way, for a small business is a viable option, since the performance depends on the degree of automation. In any case, it will be higher than when working manually.

Useful tip

If you have good skills in the locksmith trade, you can significantly save on equipment. If you look closely at the tools included in the basic set of accessories, it becomes clear that many of them can be made by yourself. You only need to be clever. And the rest. to buy separately.

tools, cold, forging, your, hands

Of course, now there are more advanced devices and apparatus for “taming” the metal without heating. But still, sometimes you have to heat the metal.

Here is an example from my own experience. Recently I decided to make a key for an antique lock and change the shape of its ring for hanging. I do not currently have any smiths of my acquaintances who used to work at plants in operation: some of them have retired, and others have had to change jobs due to the “demolition” of enterprises in the post-perestroika years.

And I had to find my own way out of the situation. In this case, too, the gas torch that I so often used was of no help. So I took a more power-consuming “tool”. a blowtorch, heated up to redness the upper part of the wrench, and then with a special hammer gave a different shape to the head of the wrench. True, the product had to be heated up several times.

Thus, a blowtorch can also be part of a blacksmith’s kit, only not a “cold” one, but a “hot” one.

For bending strip steel, which is called a profile, there have been three- and even four-roller machines for a long time now. The necessary radius of plate bending is set with special levers and handles. On these machines, all kinds of shapes can be given to sheet steel plates.

Dear Sirs! The aging of blanks is not done for “antique styling,” but for high-precision equipment. For example, in the machine tool industry.

The whole problem is that metal gets warped during aging. You can not see it with the eye, but for precision equipment an error of one-third of a millimeter is already inadmissible. This is why metal products (frames, chucks, etc) are kept for a long time somewhere in the cold and damp. And only after the aging process, such parts are processed “clean”. In order to assemble some machine from them.

DIY things you can make with your own hands

The tools necessary for cold forging, you can buy in a store. But many craftsmen use self-made parts, adapted “for themselves”, it saves money and allows working with the tool, made of improvised materials, and therefore more diverse and suitable for different tasks.

Metal parts that craftsmen use in the process of making homemade tools:

  • plates and corners of different thicknesses;
  • rods of automobile shock absorbers;
  • springs;
  • armature;
  • pipe cuttings;
  • bearing rollers and much more.

What can be made, using the technology of cold forging

All the rest will have to be purchased as needed. In principle, the capacity of cold forging is enough to assemble a beautiful lattice on a window or fence.
