筒形拉伸件模具设计论文

筒形件拉伸模具设计摘 要冲压在现代工业生产中，尤其是大批量生产中应用十分广泛。相当多的工业部门越来越多地采纳冲压法加工产品零部件，如汽车农机、仪器、仪表、电子、航空、航天、家电与轻工等行业。在这些工业部门中，冲压件所占的比重都相当的大，少则 60%以上，多则 90%以上。采纳了冲压工艺，许多工业部分都提高了生产效率和产品质量，降低了生产成本。冲压加工所使用的模具一般具有专用性，有时一个复杂零件需要数套模具才能加工成形，且模具 制造的精度高，技术要求高，是技术密集形产品。所以，只有在冲压件生产批量较大的情况下，冲压加工的优点才能充分体现，从而获得较好的经济效益。本文主要是设计圆筒形制件在冲压过程中的模具设计，并对冲裁过程中样品排样进行了设计。关键词：冲裁；模具结构设计；筒形拉伸件AbstractStamping products has been extensively applied in the industry, agriculture, national defense and in the daily lives of area, especially in the machinery industry. Mechanical products is the most pressing housing products, and the improvement of product performance requires of high-quality performance stamping molds ,stamping,process and product design. There are many ways of molding products of stamping. Piercing is mainly used for blanking, bending, stretching, etc. And Stamping molds almost form more than 60 percent of the total number. For example ,Electrical Control can be realized as semi-automatic or automatic operation.Cold-metal stamping die mainly used for the molding products, and it is very important in the production of stamping technology devices. The basic component of stamping molds is block model from top to bottom, mould plate, fixed-plate of mould plate, die inserts, raising nails, Iplate unloading I.
