小盖板的级进模具设计 摘要 本设计是小盖板零件冲孔翻孔落料级进模的设计，冲压模具主要是将板料分离或成形而得到制件的加工方法。设计零件为小盖板，是普通的厚板冲压件，尺寸精度要求不高，主要是翻孔整形问题。因为模具的生产主要是大批量的生产，而且模具可以保证冲压产品的尺寸精度和产品质量，模具设计与制造主要考虑到模具的设计能否满足工件的工艺性设计，能否加工出合格的零件，以及后来的维修和存放是否合理等。在本次设计中的小盖板中，不仅要考虑要使做出的零件能满足工作要求，还要保证它的使用寿命。 其次设计中还要考虑到它的实际工作环境和必须完成的设计任务，模架采用对角型模架，凹模采用组合凹模，这样可以采用线切割等数控设备来一次完成全部的工序加工，在设计中我要考虑到很多关于我所设计模具的知识，包括它的使用场合、外观要求等，从这里可以知道模具设计是一项很复杂的工作，所以在设计要不断的改进直到符合要求。 关键词：小盖板；冲孔翻孔落料；级进模；凹模；模具设计 Abstract This desig
