中文摘要
本次毕业设计的零件是电动机的定子转子冲片，包括零件的冲压工艺设计和模具的具体结构设计。通过对零件的工艺性分析以及考虑到生产条件的影响，设计和给出了在现有的条件下的最佳工艺方案和模具结构，比如：选择基本的工序，确定其工序顺序，工序数目及工序组合形式。然后以此为基础，设计出冲压模具的结构。结合实际，进行合理、正确的规划。在做毕业设计时候零件比较复杂，精度要求高，属于大批量生产，同时一个冲程要完成两个工件的冲制，故选择了多工位的级进模。在设计中绍了该类模具的主要设计结构和技术要求，重点介绍了该类模具的高精度制造技术和关键部位的工艺技术参数。

Abstract
    The graduation is the design of parts of the motor rotor-stator unit, including parts stamping process design and die design of the concrete structure. Parts of the Process Analysis and considering that the production conditions, Design and given the existing conditions of the optimal structure of the program and die, for example : the choice of basic processes, determine the order of processes, number of processes and process portfolio. Then as the basis for designing the structure of stamping die. In light of the actual, reasonable and proper planning. Doing graduate design parts of the complexity and high accuracy, is mass production, Meanwhile a stroke two parts to complete the flushing system, it chose the Multi-Position Progressive Die. Design presentations in the mold of such major structural design and technical requirements, focus on such high-precision mold manufacturing technology and key parts of the technology parameters.
