防尘盖冲压模具设计 1 中文摘要 模具是现代化的生产重要工艺装备，在国民经济的各个部门都越来越多地依模具来进行生产加工，越来越 引起人们的重视，模具也趋向标准化。 随着模具的迅速发展，在现代工业生产中，模具已经成为生产各种工业产品不可缺少的重要工艺设备。本设计进行了落料、冲孔、拉深复合模的设计。文中简要概述了冲压模具目前的发展状况和趋势。对产品进行了详细工艺分析和工艺方案的确定。按照冲压模具设计的一般步骤，计算并设计了本套模具上的主要零部件Abstract The mold is the modernization of production process equipment, in various sectors of the national economy is more and more depending on the mold to the production and processing, people pay more and more attention, mold trend of standardization. With the rapid development of the mold, in modern industrial production, mold has become the production of various industrial products indispensable important process equipment. The design of the blanking, punching, drawing compound die design. In this paper, a brief overview of the stamping die current development status and trends. The product of a detailed analysis and the identification process. Stamping die design in accordance with the general steps, calculate and design the sets of the main mold parts.
