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。

Abstract
This design is the design of progressive die for punching, turning and blanking of small cover plate parts. The punching die is mainly to separate or form the sheet metal to obtain the processing method of the parts. The design part is a small cover plate, is a common thick plate stamping parts, dimensional accuracy requirements are not high, mainly the problem of turning holes. Because the mold production is mainly mass production, and the mold can ensure the dimension precision and product quality of the stamping products, mold design and manufacturing mainly considerwhether the mold design can meet theworkpiece process design,whether the qualified parts can be processed, andwhether the subsequent maintenance and storage is reasonable. In this design of the small cover plate, not only to consider to make the parts to meet thework requirements, but also to ensure its service life.
Secondly, the actualworking environment and the design tasks must be considered in the design. The die holder adopts diagonal die holder and the die holder adopts combined concave die. In thisway, the NC equipment such aswire cutting can be used to complete all the processing at one time. In the design, I have to consider a lot of knowledge about the mold I designed. Including its use occasion, appearance requirements, from herewe can know that the mold design is avery complexwork, so the design should be constantly improved until it meets the requirements.
