精品文档---下载后可任意编辑摘要冲压制品已在工业,农业,国防和日常生活中的方面得到广泛应用,特别是在 机械业中则为突出。机械产品的外壳大部分是冲压制品,产品性能的提高要求高素养的冲压模具和冲压性能,成型工艺和制品的设计。冲压制品的成型方法很多.其主要用于是冲孔,落料,弯曲,拉伸等.而冲压 模,约占成型总数的 60%以上。当然如利用电气控制,可实现半自动化或自动化作业。冷冲冲裁模主要用于金属制品的成型,它是冲压制品生产中十分重要的工艺装 置.冲压模的基本组成是:上下模座、下模垫板、下模固定板、凹模镶块、抬料钉、导料板、卸料板、导柱导套、卸料板弹钉、卸料板等。冲裁模成型的广泛适用,正是我这个设计的根本出发点。本文是对接触簧片级进模的设计，第二章进行了工艺分析和三种排样方法的对比选择；在第三章进行了冲压力和冲压中心的计算；第四章主要进行了模具的结构设计，包括凸凹模、凸模固定板、垫板、卸料部分、凸凹模工作尺寸及冲裁间隙；另外在第六章进行了剩余模具零件的设计和强度校核。关键词:接触簧片；冲裁件；冲压模；级进模精品文档---下载后可任意编辑Reed contacts Progressive Die DesignAbstract Stamping 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 semiautomatic 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...
