1、异形复杂连接件模具设计SHAPED MOLD DESIGN COMPL EXCONNECTIONS专 业:材料成型及控制工程(模具)姓 名:指导教师姓名:申请学位级别:论文提交日期:学位授予单位:摘 要本说明书详细论述了异形复杂连接件级进模具设计的全过程。冲压模具是指在冲压过程中,将材料(金属或非金属)加工成零件(或半成品)的一种特殊工艺装备。此模具包括了冲孔、弯曲等基本工序,共九个工位。说明书中介绍了制品的工艺分析,排样的设计,压力中心的确定,压力机的选择,主要工作零件工作部分尺寸计算与校核,弹性元件的选取等内容。本次设计采用了双侧刃和侧刃挡块定距和挡料板定位的形式,保证了板料送进的可靠性,
2、并且采用浮顶装置,能够使板料顺利通过模具并冲压成型。由于此制件冲压精度要求不高,故只在关键部位设置了导正销,提高了冲裁或者弯曲精度。本套模具采用向下弯曲形式,使凹模制造简单,浮顶距离降低,保证了制造精度。在最后一工位采用弯曲冲孔一步进行,不但降低了模具制造难度,而且还节省了模具材料。关键词:级进模; 双侧刃; 冲孔与弯曲; 多工位ABSTRACTThe instructions discusses in detail the complex shaped connecting piece progressive die design process.

5、eed reliability sheet fed, and uses floating roof device, enabling smooth passage of the mold and sheet metal stamping. Because of this less precision stamping parts, it only sets the lead in key positions are eliminated to improve the precision punching or bending. The molds used bent down form, so
