Stamping is a kind of forming processing method which relies on press and die to exert external force on plate, strip, pipe and profile to produce plastic deformation or separation, so as to obtain the workpiece (stamping part) with the required shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The stamping blank is mainly hot-rolled and cold-rolled steel plate and strip. In the world’s steel, 60-70% are plates, most of which are made into finished products by stamping. Car body, chassis, fuel tank, radiator, boiler drum, container shell, motor, electrical iron core, silicon steel sheet, etc. are stamping processing. There are also a large number of stamping parts in instruments, household appliances, bicycles, office machinery, household utensils and other products.
According to the stamping 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 sheet metal. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to material forming engineering technology.
The die used in stamping is called stamping die, which is a special process equipment to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping process. It is called cold stamping die (commonly known as cold stamping die). Stamping die is a special tool for batch processing materials (metal or non-metal) into required stamping parts. Stamping die is very important in stamping. If there is no qualified stamping die, it is difficult to carry out batch stamping production; Without advanced die, advanced stamping process can not be realized. Stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping process. Only when they are combined can stamping parts be obtained.
