冲压工艺及模具设计 摘要 冲压是利用安装在冲压设备（主要是压力机）上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件的一种压力加工方法。切边是将板料、棒料、管材和型材切边成一定角度和形状的冲压成形工序。本设计针对导电片零件冲压成形工艺及其落料冲孔复合模具设计，利用Auto CAD软件对制件进行设计绘图，明确了设计思路，确定了冲压成型工艺过程并对各个具体部分进行了详细的计算和校核。利用导电片零件冲压成形工艺及其落料冲孔复合模具设计特征之间的关系建立模具排样设计模型，引如冲压排样设计原则；进一步将零件的形状特征应用于模具结构设计中，建立模具模型，进行模具工艺设计和结构设计，从而确定总体的模具形式；模具投入制造后，可能在制造和生产过程中表现出设计的不足和错误，通过总结概括这些问题，可以进行模具结构设计，或增加新的工艺规则，为以后的模具设计提供宝贵的经验。 关键词： 模具设计，冲压模具 Abstract Stamping is installed in the use of stamping equipment (mainly Press) on the mold to exert pressure on the material, to produce plastic deformation or separation, thus obtaining a pressure parts processing methods.
