端盖冲压成形工艺及模具设计 摘 要：本设计课题介绍了盒形盖体落料拉伸复合模的结构设计及工作过程。针对零件落料后口部呈尖锐刃口状现象，改进了模具结构，消除部分加工缺陷，分体现了冲压工艺先进性和高效性,有一定的设计意义。通过对工艺零件的工艺分析及模具结构设计, 巩固所学的知识、熟悉有关资料,树立正确的设计思路,加强了对模具的整体认识,提高自己的实际模具设计工作能力。本计运用了冲压成形模具设计的基本知识，首先对整个零件的了解分析工艺参数,冲压工艺性能,然后确定冲压模的结构形式，工零部件的设计与计算，落料和拉深在一个工序上完成，本副模具优点结构简单紧凑，易于加工维修，。关键词：工艺分析, 拉深成形,落料 Cover Tensile Trimming Composite Modulus Design Abstract：The design issues on the box-shaped body covered crowded tensile shear modulus of the composite structure design and working process. Against cutting crowded parts after mouth was sharp blade-like phenomenon, improve the structure of the mold and eliminate some processing defects, embodies the Analysis and Die of the composite structure Design ,consolidate the knowledge acquired and are familiar with relevant information, establish the process advanced and efficient.So this design has a certain of significance. Through of the parts of the process design ideas, the right to strengthen the overall mold and enhance awareness of their actual ability to mold design.Total use of the stamping die design of the basic knowledge, the first part of the whole understanding、analysis of process parameters, stamping process performance, and then determine the structure of stamping die form, the design and calculation of the components, Drawing and trimming processes in a complete, the vice die advantages of simple structure compact and easy maintenance processing, shortcomings pick-up
