The stamping die is used for sheet metal stamping and separation. The molding tool has a cavity, and the parting tool has a cutting edge. The most commonly used stamping die has only one workstation, which completes a production process. The mould is widely used, simple in structure, easy to manufacture, but low in production efficiency. In order to improve productivity, can be more than stamping process, such as blanking, deep drawing, punching and trimming arranged on a mold, to make blank on a workstation multichannel stamping process, this mould is called composite modulus.
Otherwise the blanking, bending, drawing, punching and trimming process in a different location on the mould, billet in the process of stamping, in turn, be continuous through transfer stamping, to become parts for the last station, this mould is called progressive die, also called progressive dies.
The stamping die is characterized by high precision and accurate size, and some blanks of punch die and die are close to 0. Fast stamping speed, capable of punching dozens to thousands of times per minute; The die life is long, some silicon steel sheet blanks die to die several million times.
