Forging is a combination of forging and stamping. It is a forming processing method that uses hammers, anvils, punches or dies of forging machinery to exert pressure on the blank to produce plastic deformation, so as to obtain the required shape and size.
In the forging process, the billet has obvious plastic deformation and a large amount of plastic flow; In the stamping process, the blank is formed mainly by changing the spatial position of the area of each part, and there is no plastic flow within the blank with a large distance.
Forging is mainly used to process metal parts, but also can be used to process some nonmetals, such as engineering plastics, rubber, ceramic blanks, brick blanks and the forming of composite materials. Rolling and drawing in forging and metallurgical industry are all plastic processing, or pressure processing, but forging is mainly used to produce metal parts, while rolling and drawing are mainly used to produce general metal materials such as plates, strips, pipes, profiles and wires.
Forging is a combination of forging and stamping, like industry and trade, also known as industry and trade.
Stamping is the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment to make the sheet directly subject to deformation force in the mold and deform. Sheet metal, die and equipment are the three elements of stamping processing. According to the stamping processing temperature, it can be divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; The latter is carried out at room temperature, which is a common stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to material forming engineering technology.
