片体冲压工艺及模具设计
摘 要
摘 要：模具是工业产品生产使用的重要工艺装备，它以其自身的特殊形状通过一定的方式使原材料成型。现代工业生产中，由于模具的加工效率高，互换性好，节省原材料。片体作为必不可少的零件，在级进模具行列里也比较经典，所以在这次课题的选择里，特选择了片体作为自己的挑战项目。
这副级进模内可以包含冲裁，切口，落料等多道工序，一台冲床可完成从板料到成品的各种冲压过程。它免去了用单工序模的周转和每次冲压的定位过程，提高了劳动生产率和设备利用率。
模具技术已成为衡量一个国家制造水平的重要标志之一。模具技术能促进工业产品的发展和质量的提高，并能获得极大的经济效益。模具是效益放大器，用模具生产的产品的价值往往是模具价值的几十倍、上百倍。
关键词：片体冲孔、切口、落料
Abstract:
Mold,which is used to would raw material due to its special shape, is a piece of important equipment in the process of producing industrial products. It is wildly used in modern industry, because of its effective machining, exchangeable quality, saving raw materials and lower costs. As an essential part of the body, in the progressive die is more classic, specially selected the sheet body as their own challenges.
This pair of progressive die can be include within the incision,punching,blanking and other processes,can be completed in one machine,all kinds of stamping process that product.It eliminates the localization of single process mode turnover and every time stamping process, improve the utilization rate of labor productivity and equipment.
one important way of measuring the manufacture level of country is the technology of mold,which can advance the quality of products and promote its development and gain great economical benefits, Mold is effective amplifier.Products with the value of the mold is often ten times and a hundred times the value of the mold,.
Keywords: Sheet punching, cut, blank.
