The high-voltage motor punching die consists of multiple workstations, each of which is sequentially associated to complete different processing, completing a series of different punching processes in one stroke of the punch press. After completing one stroke, the material is moved forward by the punching machine according to a fixed step distance, so that multiple processes can be completed on one mold, generally including guide holes, rotor punching slots, rotor dropping, stator punching slots, stator punching points, stator dropping, stator stacking, etc. There are usually 5-7 workstations. After each stamping of the mold is completed, the material strip moves at a fixed distance until the product is completed.

The characteristics are: 1) Progressive die is a multi task sequential punching die, which can include multiple processes such as punching, bending, and stretching in one mold, with high productivity; 2) Progressive mold operation safety; 3) Easy to automate; 4) High speed punching machines can be used for production; 5) It can reduce punching machines, site area, transportation of semi-finished products, and warehouse occupation.
