[0002] A punching die is a tool used to punch holes in materials, usually used for processing materials such as metal plates, plastic plates, and paper. The working principle of the punching die is to use the punch and die on the die to apply pressure on the material, causing the material to deform between the punch and die, thereby forming the desired punching shape. The design and manufacture of the punching die need to take into account factors such as the properties of the material, the shape and size of the punching, the material of the die, and the processing technology. Usually, the punching die consists of a die base, a punch, a die, a guide device, a discharge device, and other parts.
