[Abstract]:By analyzing the structural characteristics and stamping process characteristics of the stator parts of 3D printer motor, the plastic superposition principle of multi-position progressive die stamping stator parts is introduced. The characteristics of layout design and special structure device are as follows: (1) the superposition plastic forming point of stator parts adopts circular shape; (2) the layout scheme includes: main punching hole, 8 small holes and the first pre-punching hole, punching groove form, punching plastic forming riveting point metering hole, the final dimension of the second punching inner hole, punching stator tooth shape and plastic forming riveting point hole, air walking, Seven processes of stator blanking and superposition plastic forming; (3) the thickness control structure of superposition plastic forming products of stator parts, the accurate positioning structure of guide pin and the structure of fault detection. The experimental results show that the superposition structure of the plastic forming technology for stamping stator parts on multi-position progressive dies can shorten the production time of stator parts, reduce the labor intensity and ensure the precision of the products, compared with the single stamping process of common die. To meet the needs of mass production.
