端盖的冲压工艺及模具设计摘要：此次毕业设计任务是端盖零件的模具设计。端盖为有凸缘圆筒形件，是典型的拉深件，其拉深过程中变形区的应力状态和变形特点与无凸缘圆筒形件是相同的，但有凸缘圆筒形件拉深时，胚料凸缘部分不是全部进入凹模洞口，当拉深进行到凸缘外径等于零件凸缘直径时，拉深工作就停止。良好的工艺性和合理的工艺方案，可以用最少的材料，最少的工序和工时，使得模具结构简单且模具寿命长，能稳定的获得合格冲裁件，通过分析端盖的工艺性，确定合理的工艺方案；通过计算端盖的相对直径或者相对高度，判断端盖能否一次拉深成功，从而确定拉深工艺参数以及模具工作部分的几何形状与尺寸；根据计算结果选用标准表架。关键词：端盖 应力状态 工艺性 工艺方案 拉深次数 Gasket ramming craft and mold designAbstract：This mission is designed graduate washers parts mold design. Gaskets for flange cylinder-shaped pieces, is typical of drawing parts, Drawing its process of deformation of stress and deformation characteristics and without flange cylinder-shaped pieces are the same. But flange cylinder-shaped drawing, blank flange is not something all entered Die holes When drawing for diameter of the flange to flange diameter parts, drawing on the work to stop.Good technology and good process, with the least material, at least the processes and working hours. make simple structure Die Mold longevity, stability can be qualified blanking through analysis of the washers, determine reasonable process; By calculating the relative diameter washers or relative height, Can a judge washers Drawing successful, in order to determine drawing process parameters and die part of the geometric shape and size; According to the results table-selection criteria.Keywords : Washer Strai
