Cold forging allows you to make beautiful and original things without heating the metal and the associated difficulties. She can become a worthy male hobby or bring real income - after all, forged fences, fences, chairs are not cheap at all.
DIY cold forging equipment
First of all, for work you will need a welding machine, a cutting grinder (grinder), a cleaning grinder and a perforator. The latter is needed mainly for the installation of finished products. In addition, a special tool is required. To create products on an industrial scale, it is better to buy equipment for cold forging of well-known and proven brands, but if you just need to make a fence or a forged lattice on the windows, you can do it with improvised means.
Manufacturers offer the following tool. The flashlight allows you to twist the welded squares so that they are evenly spaced in the center. The "Gnutik" rig is designed to bend elements at a desired angle or along an arc of a given radius.
With the help of the "Volumetric", you can bend the rods in a certain arc, and then at a right angle, this is an important equipment for creating fences, balcony and window grilles. There is also cold forging equipment that allows you to twist squares around an axis, create spiral curls or waves.
Cold forging technology
First of all, you need to decide on a sketch of the entire product and individual parts. All work with the elements should be worked out on unnecessary, waste material, so as not to spoil the metal and fill your hand. Having set all the settings on the equipment, you can get to work.
Some parts need to be welded together before bending. It is more convenient to cut blanks from sheet metal using special stencils or templates. The big advantage of cold forging in comparison with hot forging is precisely the ability to create standard, identical parts, therefore, in general, the product turns out to be symmetrical and accurate.
To make the overall look more accurate, you can heat the edges of the product and the joints with a blowtorch, achieving smoothness. At the end of the work, all seams are cleaned, scales and irregularities are removed, the product is sanded and painted.
