精品文档---下载后可任意编辑本次毕业设计的零件是侧孔深筒，制定出相关工艺路线并设计出生产所需模具。主要工序有：a 落料，b 拉深，c 二次拉伸，d 切边，e 冲孔，去除毛刺。采纳落料拉深复合模，可以较好的实现落料，设计过程中应当充分考虑该落料拉深复合模的刃口形状及尺寸，否则容易影响到落料拉深件的形状及尺寸。本篇论文综合应用本专业所学课程的理论和生产实际知识,并且查阅了大量课外资料，进行的一次冷冲压模具设计工作的实践训练。在本次模具设计中，本着降低模具复杂程度及成本的原则，把落料模具、拉深模具做成一套复合模，然后独立设计一套侧冲孔模具。本套模具性能可靠，提高了产品的成品率和生产效率，可以大幅度降低劳动强度和生产成本。在模具设计中，查阅了大量课内和课外的文献资料，充分利用已经掌握的知识，使模具设计尽量简单并且能达到最大的有用效果。关键词：侧孔深筒 模具设计 落料 拉深 侧冲孔AbstractThe graduation project is part of deep tube side holes, to develop and design the associated process route for production molds. The main steps are: a blanking, b drawing, c second stretch, d trimming, e punching, deburring. Using a composite blanking drawing die, you can achieve better blanking, the design process should take full account of the composite blanking drawing die edge shape and size, or likely to influence the shape and size of blanking drawing parts. In this thesis, comprehensive application of the theoretical and practical knowledge of the production of professional learning courses, and access to a lot of extracurricular information, practical training conducted by a cold stamping die design work.In this mold design, mold principle to reduce the complexity and cost of the blanking dies, molds made of a composite drawing die, and then design a separate side punching die. The sets of molds and reliable performance, improved yield and production efficiency can greatly reduce labor intensity and production costs. In the ...
