摘要：

针对冲压加工的分离器零件存在底面上小孔密集、零件翻边、凸包部分结构形状复杂及尺寸精度要求高等特点，本文进行了零件排样及模具结构设计。除了采用提高模具精度和定位精度等常规措施外，还采取了精确坯料形状、两次凸包和密集小孔分步冲出等措施来解决上述问题；针对常用带料防误送装置使模具整体尺寸增大的缺陷进行了带料防误送装置结构的重新设计；并通过在模具上增加内限位柱的措施解决了零件的表面压痕缺陷；整套模具采用三维设计，方便后续数控加工程序的生成。

In view of the characters of intensive small holes in the bottom, flanging, convex hull with structure of complex shape and dimensional accuracy high require of stamping separator parts, the layout of parts and the mold structure design were studied. Besides using the traditional methods to promote the mold and positioning precision, the new methods of precise shape of the blank, twice convex hull, intensive small holes stamped step by step etc. were adopted. The structure of strip anti-misdirected equipment was redesigned to solve the problem that the whole size of the mold increased caused by the often using of equipment. The surface indentation flaw of parts was solved by setting the internal limit column in the mold. Using the three dimensional design of the mold, the subsequent NC machining program was convenient to generate.
