内容简介：

第 1 页 共 2 页散热片零件冲压工艺及模具设计摘 要冲压是在室温下，利用安装在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。冲压模具在冷冲压加工中，将材料（金属或非金属）加工成零件（或半成品）的一种特殊工艺装备，称为冷冲压模具（俗称冷冲模） 。冲压模具是冲压生产必不可少的工艺装备，是技术密集型产品。冲压件的质量、生产效率以及生产成本等，与模具设计和制造有直接关系。模具设计与制造技术水平的高低，是衡量一个国家产品制造水平高低的重要标志之一，在很大程度上决定着产品的质量、效益和新产品的开发能力。关键词： 凸模 凹模 压力机吨位 第 2 页 共 2 页散热片零件冲压工艺及模具设计Abstract：A complete press tool for cutting two holes in work material at one stoke of the press, as classified and standardized by a large manufacture.Any complete press tool, consisting of a pair of mating member for producing pressworked parts ,including all supporting and actuating elements of the tool ,is a die .pressworking terminology commonly defines the female part of any complete press tool as a die.A punch holder mounted to the upper shoe holds two round punches which are guided by bushings inserted in the stripper.A compound die performs only cutting operations which are completed during a single press stroke. A compound die can produce pierced blanks to close flatness and dimensional tolerances. A characteristic of compound die is the inverted position of the blanking punch and blanking die. The die is fastened to the upper shoe and the blanking punch is mounted on the lower shoe. The blanking punch also functions as the piercing die ,having a tapered hole in it and in the lower sho
