The introduction of stamping

Stamping is to rely on the press and die on the sheet, strip, pipe and profile to exert external force, so that the plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping parts) forming processing method. Stamping and forging belong to plastic machining (or pressure machining), collectively known as forging. The blank for stamping is mainly hot and cold rolled steel sheet and strip. Of the world's steel, 60 to 70 percent are sheets, most of which are stamped into finished products. Automobile body, chassis, oil tank, radiator piece, boiler drum, container shell, motor, electrical appliances of the iron core silicon steel sheet and so on are stamping processing. Instruments, household appliances, bicycles, office machinery, household utensils and other products, there are also a large number of stamping parts.

Stamping processing is the power of conventional or special stamping equipment, so that the sheet metal in the die directly by the deformation force and deformation, so as to obtain a certain shape, size and performance of product parts production technology. Sheet material, die and equipment are the three elements of stamping process. According to the stamping processing temperature is 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 and is a common stamping method for sheet metal. It is one of the main methods of metal plastic machining (or pressure machining), and also belongs to the material forming engineering technology.
