Stamping die is a special equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in the process of cold stamping, which is called cold stamping die (commonly known as cold stamping die). Stamping is a kind of pressure processing method at room temperature, which uses the die installed on the press to exert pressure on the material to make it separate or deform plastically, so as to obtain the required parts.

There are many forms of stamping dies, and stamping dies are also classified according to working nature, die structure and die material.

According to the processing method of the product:

According to the different processing methods of products, dies can be divided into five categories: stamping and shearing dies, bending dies, drawing dies, forming dies and compression dies.

A. Punching and shearing die: the work is accomplished by shearing. The common forms are shearing die, blanking die, punching die, trimming die, edging die, hole drawing die and punching die.

B. Bending die: bending a flat blank into an angle. According to the shape, precision and output of parts, there are many different types of dies, such as common bending die, cam bending die, curling die, arc bending die, bending punching die and torsion die.

C, die drawing: die drawing is to make a flat blank into a seamless container with a bottom.

D. Forming die: refers to changing the blank shape by various local deformation methods, including convex forming die, curling forming die, necking forming die, hole flange forming die and round edge forming die.

E. Stamping die: The metal blank is deformed into the required shape by strong pressure, and its types include extrusion die, embossing die, embossing die and end stamping die.
