[0002] The stamping device for motor parts is mainly used for stamping motor parts. Stamping is a forming processing method that uses a press and a die to apply external force to plates, strips, tubes, profiles, etc., so that they undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) with the required shape and size. In the production process of motor parts, stamping plays an important role because it can, according to the given product drawing, through stamping process design, formulate a reasonable process plan, and design stamping dies accordingly. These dies can adapt to different production batches, specifications of stamping equipment, die manufacturing capabilities, and the technical level of workers, etc., to ensure the quality, cost, and production efficiency of stamping products.

[0003] The existing stamping head of the upper die of the die stamps the motor parts on the die cavity of the lower die. However, the existing stamping device for motor parts still has the following problems during use:

[0004] For the stamping of different parts of existing motors, the die needs to be frequently replaced on the traction mechanism. Since the lower die of the die is fixed on the bearing platform by bolts, and the upper die of the die is fixed on the traction mechanism by bolts, this leads to cumbersome loading and unloading, reduces work efficiency, and increases work intensity. Therefore, it is very necessary to involve a stamping device for motor parts that is convenient for replacing dies in the existing field of motor part processing. Content of the Utility Model
