摘　　要：尽管模具的设计和制造技术都已成熟,但经验化设计和制造仍占主导作用,特别是模具的配作加工对装配工人的技术要求非常高。对现存模具刃口尺寸和公差计算方法进行优化,结合"入体原则"和孔类、轴类尺寸偏差特点,建立了针对一般性冲压模具刃口尺寸和公差的分开加工计算方法。针对重要工作零件进行ANSYS有限元应力分析,校核其强度。对于整套模具通过理论设计、三维建模和零件加工工艺概述,分析其设计和装配的合理性。利用该计算方法完成了电机定子硅钢片冲压模具刃口的计算,从理论设计上实现了降低装配工人技术要求的目的。Although the die design and manufacturing technologies have been developed ma- turely, the experience-based method still play a significant role during the die design and manufacturing. Especially, the matching process needs a high requirement of assembly workers. In this paper, combined with the ＂entry body＂ principle and the characteristics of the size deviation of hole and shaft, a general calculation method is established to determine the dimension and tolerance of the die cutting edges by optimizing the traditional methods. The die design of silicon steel sheet is finished using this calculation method. Based on AN- SYS, the stress states of some critical parts are analyzed to verify the strength. According to the theoretical design, the 3-D modeling, processing description, the rationality of the design and assembly are investigated. Using this method, the calculation of the die cutting edge for the silicon steel sheet is carried out, and the requirements of the assembly workers are also reduced through the theoretical design and investigation.
