中文摘要

通过分析电机盖端的结构特点，确定了其冲裁工序、拉伸序及各工序件的尺寸，介绍了整体模具的工艺设计，重点分析了拉伸模结构。冲压模具的设计方法在当下已经日趋成熟，利用传统的设计手段对电机罩壳进行完整的复合模设计。通过对零件结构的分析制定可行的工艺方案，并进行最优化选择。在完善的工艺方案基础上，对每一个工序进行工艺计算，得到准确的数据。通过参考经典的模具结构，对复合模进行结构设计。并通过计算数据对标准及非标准零件进行查找和设计。利用三维造型软件proe4.0对模具的零部件进行绘制，并进行装配得到装配图。结合proe4.0的工程图绘制功能以及二维绘图软件CAD，对三维零件及装配图进行二维工程图的绘制。传统设计方法与绘图软件的结合，一定程度上简化了模具设计的过程，提高了模具设计的效率，为冲压模具的更好发展打下了基础。

Abstract

Abstract: Through analyzing on the structure characteristics of the electrical machinery end cover, determined its blanking working procedure, the drawing working procedure and various working procedures size. The process design of the while die were introduced, mainly analyzed on the drawing die structure. The design method of stamping die is becoming mature, and traditional design method is using to design compound die of motor casing. Analyzing the part structure to make feasible process scheme, and select the optimal plan. On this basis, make the process calculation of each procedure. Consult classical die structure to design the compound die. Followed that, search the standard parts and design the nonstandard parts of compound die. Using 3D modeling software proe4.0 to draw the components of die, and assembling them to get the assembly drawing. After that, make the 2D engineering drawing by the combination of proe4.0 and CAD. The process of die designing is simplified to some extent, because of the coordination of traditional design method and drawing software. Moreover, the efficiency of die designing is improved, and it lays the foundation to the better development of stamping die.
Key words: electrical machinery en cover; the pressure process ; progressive die; die design.
