Cold forging is a metal forming with the help of special tools – dies. The stamp consists of two parts: top and bottom, is placed between the material being processed. Giving material the desired shape is achieved in that the upper part of the stamp is putting pressure on the material placed on the bottom of the stamp, and makes him take the form of cavities of the stamp. The pressure produced by the press, having a moving slider, which is attached to the movable part of the stamp. Since the work is done without heating the metal, then this method of stamping is called cold stamping. The working parts are die punch – upper punch and the matrix – the lower part of it.
Punch attached to their tail slide in the press, and the matrix set and still fixed on the table press. Cold forging is widely used in various industries industry. By cold forging manufactured large and complex parts such as automotive frames, as well as small items, such as arrows for instruments and watches. Technical advantages of cold forging is the ability to: 1. perform complex operations through the press blows 2. receive interchangeable parts of the same size 3. get very complicated product shapes that are difficult to produce by other means, 4. reduce the number of operations and simplify the production process 5.
create a strong but lightweight construction products, consuming a small amount of material. Economic benefits of cold-formed metal: 1. economical use of the material with a small quantity of waste, 2. high-performance press, greatly exceeding the performance of other types of equipment, 3. easy to operate presses, 4. low cost moldings.
