介绍了电机全复式定子冲片和转子圆片一次冲压成型的落料工艺,通过阶梯冲实现定子内外圆、定子槽型、转子内外圆的分离。该工艺关键点在于转子凸凹模,其既是刃口又是卸料板,全部采用模具钢制造。整个冲裁过程仅需一道工序即可完成,生产效率大幅提高,节省了人力,降低了生产成本,提高了定子冲片精度。

Compound introduced the motor stator laminations and rotor discs a stamping forming of blanking die, stator laminations, rotor discs by ladder rushed inside and outside the stator, rotor, stator groove inside and outside the circle round the separation of the mold in the key rotor intensive was both a blade and a stripper plate, all adopt the die steel manufacturing. The whole cutting process, a process with only could complete, greatly increased production efficiency, saves the manpower, reduces the production cost, improved the precision of the stator laminations.
