内容简介：

圆筒冲压工艺及模具设计摘要： 本设计设计的是筒形件的落料拉深复合模，首先根据计算来确定拉深次数，通过查资料计算修边余量、拉深毛坯直径等。通过对冲压力计算来初选压力机，对工件的零件、模具工作部分（如凸凹模、拉深凸模、落料凹模等）和模具的整体设计来确定模架，最后选择中间导柱模架。对压力机和模具校核后来确定压力机。本次设计的主要内容为：工件的工艺性分析、冲压工艺方案的确定、模具的技术要求和材料选用。主要尺寸计算、工作部分尺寸计算、模具整体设计和主要零部件结构设计、模具装配和模具总装图。关键词：模具，复合模，压力机，拉深Cylindrical stamping process and die designAbstract: this design is design of cylindrical parts blanking deep drawing composite modulus, first of all, according to the calculation to determine the number of deep drawing, trimming allowance by check information calculation and drawing blank diameter, etc. Primary press through hedge pressure calculation, parts, mould work part of the workpiece (such as intensive, drawing punch, blanking die, etc.) and the integral design of the mould to determine the die set, finally choose the middle column formwork. The press and die check later determined press. The main content of this design is: the artifacts manufacturability analysis, the scheme determination of stamping process and die technical requirements and material selection. Main size calculation, working part size calculation, die major parts of the overall design and structure design, mold assembly and mo
