Ornaments and furnishings made of wrought metal have always enjoyed steady popularity. They are not only famous for their aesthetic appearance, but also for their extraordinary durability and long service life. Such items are usually able to serve several generations of owners, being inherited from father to son. In addition, the process of forging metal to create art products is always made by hand, so each product is exclusive and somewhat different from similar analogues.
With the help of cold forging, you can make exclusive forged products at home.
Meanwhile, such products can be produced not only with the use of thermal heating, with which the concept of forging production is traditionally associated, but also by cold forging. If the first requires both a blacksmith's forge and a special qualification, the second is quite available for independent production at home. In this way, you can make window grilles, fences for front gardens and garden plots, railings for stairs and balconies, canopies over the doors, as well as interior items such as chairs, beds, sofas and fireplace grates, flower stands and fireplace accessories. Each such homemade item will be exclusive.
Features of the process of cold forging
Tools for cold forging.
The main difference from the hot forge process is that the metal parts are bent to a cold one, without the use of thermal glow. This leads to the fact that for this process you can use a metal bar with a thickness of no more than 30 mm or a square of no more than 16 mm, since its main engine is muscle strength. You do not need a specially equipped workshop, they can be practiced in a regular barn or garage. The only thing to remember is that a welding machine will be needed to join the curved parts into a single structure, and a grinder will be needed to clean the welds.
Since far from everyone has great physical strength, special tools are needed for cold-forging with their own hands. Passing through them, the metal blanks simultaneously undergo a process of pressing and bending. Since this material is further strengthened, it is extremely difficult to damage the metal part in the future. On the other hand, if a part is made incorrectly, it is almost impossible to alter it, unlike hot forging. The only real way - is to cut it with a grinder and cook, giving the desired position.Back to table of contents
Necessary tools for cold forging
Blacksmith workplace equipment.
Since the process of forging with your own hands occurs without changing the properties of the metal, the main lever in it is the rule of the lever. It is based on almost all tools for cold forging.
Modern industry produces them in considerable quantities and a rich assortment, but the demand for them is quite high, and therefore prices in commercial establishments are seriously overestimated. Meanwhile, their device is quite simple, and tools for cold forging, with a welding machine and some skills in metal processing, are not so difficult to make with your own hands.
By the principle of work, these are hand tools, but cold forging with their help is quite successful. Their various types are able to bend metal in the form of the most popular figures.
General view of the cochlea for cold forging.
If cold forging is more or less periodic, then you need to install tools in the workshop such as:
- Snail. It is a thick iron cylinder with a hole into which the end of the rod is inserted. The disk can rotate around its axis, and next to it is installed a hard stop in the form of a spiral, along which the metal will bend. On the cylinder there is a long handle that rotates the whole fixture.
- Gnutik. The tool allows you to bend the workpiece at a certain angle and is a hole in a fixed base with an emphasis. With it, you can bend it in the form of an arc with a predetermined radius.
- Wave. This tool is a system of a fixed stop and two rollers, one of which is fixed motionless, and the second is movable and equipped with a lever. It allows you to bend the workpiece in the form of a wave with the same amplitude.
- Twister It is a movable longitudinal clamp capable of rotating around its axis, and the same clamp, only fixed. The tool helps to twist the workpiece with a screw along the longitudinal axis. In order for this process of cold forging to take place accurately, both stops must be installed on the same rigid axis. If the movable clamp can move along it, it will be possible to process workpieces of various lengths.
How to make a tool for cold forging?
Almost all the necessary tools can be made from the parts found at the scrap metal collection points. The main thing you need is a welding machine, a drilling machine and a grinder. For cold forging with your own hands, you can make almost all the tools, and products can be collected from the resulting parts of almost any. They can be used both for personal consumption and made to order for sale.
Cold forging does not require large financial expenditures and investments, however, it can both help to save a family budget and earn good money.
If for such a metal forging to make all the necessary tools, it will very quickly justify the time, effort and materials spent on its manufacture.
