1、进气管后改板摘要拉深是利用有一定圆角半径的拉深模，将平板毛坯或开口空心毛坯冲压或容器状零件的冲压过程。拉深模主要分为一次拉深和两次拉深或再拉深的多次拉深模。本套模具；拉深较浅，经过计算一次拉深成行。此套模具的总体设计思想是把经济、合理、实用作为最基本的出发点，从坯料排样到模具设计与制造，都严格遵循在整套模具设计过程中，涉及到许多工序。在对零件工艺性分析时，首先要考虑的问题是制件的精度要求，然后对各尺寸以及形状进行详细分析；工艺方案拟定时，列出各种可行的方案，比较取最佳，即为工艺方案；各工艺参数的计算和确定必须做到有据可依，有书可查，以确保
2、计算结果的可靠性。。通常，没有压边圈的模具主要用于拉深较浅的零件或不会产生一些常见起皱的厚板料。带弹簧或橡皮垫的压边圈，一般固定在上模，它们主要用在浅拉.在本次拉深模设计中，是具有压边圈的首次拉深.气垫带动压边圈，拉深凸模放在下模座中，拉深凹模放在上模座中。在设计制件时，总共用了两道工序，一道工序是拉落料边拉深，另一道工序切边冲孔。关键词：拉深模，工序，工艺方案ABSTRACTPullthedeeptomakeuseoftohavethedeepmoldofpullingofradiusofcertaincircleCape,andwas
