7、计说明书.(A4纸打印)工件图工件名称：垫片工件简图：如图所示生产批量：大批量工件材料：紫铜材料厚度：1mm一.冲压件工艺性分析此工件只有冲孔和落料两个工序。材料为紫铜，具有良好的冲压性能，适合冲裁。工件结果简单，有2个直径10mm的孔；孔与孔，孔与边缘之间的距离满足要求，工件的尺寸全部为自由公差，可看着IT14级，尺寸精度底，普通冲裁就能满足要求。-13-二.冲压工艺方案的确定该工件包括落料冲孔两个基本工序，可有以下三种工艺方案：方案一：先落料，后冲孔。采用单工序模生产。方案二：落料—冲孔复合冲压。采用复合模生产。方案

8、三：冲孔—落料级进冲压。采用级进模生产。方案一模具结构简单，但需要两道工序两套模具，成本高而生产效率低，难以满足大批量生产要求。方案二只需一套模具，工作精度及生产效率都比较高，但制造难度大，并且冲压成品件留在模具上，清理模具上的物料影响冲压速度，操作不方便。方案三也只需要一副模具，生产效率高，操作方便，设计简单，由于
