摘　　要：针对传统大、小槽加工模具单槽排样、效率低、成本高、周期长的问题,设计了一种电机定子大、小槽变排样结构的冲压单冲模。试制了不同槽形匹配和槽数匹配的各种方案,确定了最佳槽数排列。所设计的模具能满足双槽定子的一次冲裁,有效降低电机杂散损耗和电机温升,降低槽形调整时更换模具的成本和周期。Aiming at the technical problems of traditional large and small slot punching die molds with single slot layout,a punching die with variable layout structure for large and small slots of motor stator is designed.Various schemes with different slot shape and slot number were trial-manufaltured,and the optimal slot number arrangement was determined.The designed die can punching the double-slot stator,effectively reduces motor stray loss and motor temperature rise,reduces the cost and cycle time of changing die during slot adjustment.
