Background

The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly called a cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part. The stamping die may be divided into a blanking die, a bending die, a drawing die, a forming die, and the like according to process properties. For parts which need to be produced in batches and have different types or partial shapes, the existing stamping die is inconvenient to operate, cannot be used for rapidly replacing the die for production, and has high requirements on the precision of the replacement of the die. To this end, we propose a press die that solves the above problems.
