AI Technical Summary
Technical Problem
When existing high-speed stamping molds stamp stator or rotor, the thickness of the finished product is uneven due to uneven plate thickness, which affects the production quality.
Method used
A stator rotor stamping mold is designed, using a rotatable rotary sleeve. During the stamping process, the rotary sleeve is driven to rotate by a driving motor, and the stator or rotor after stamping is rotated to compensate for the thickness difference and make the finished product thickness uniform.
Benefits of technology
Through the design of the rotary swivel sleeve, the thickness of the stator or rotor is uniform, the finished product quality and stamping precision are improved, the overall structure is compact and the operation is simple.
