On the one hand, through the use of national standards and mechanicalanalysis to design apractical mold; On the other hand, through the use of CAD, Pro/E and other computer software technology to shorten the product development cycle. This can accelerate the progress of the entire process, ocupied the consumer mind market, and accumulate resources for the subsequent price competition between the same products .Keywords: Die for Rack frameBlanking diePiercing dieBending dieProtruding dieConcave die BlankingforcePunching forceUnloading forceBending forceTop pieces force精品文档---下载后可任意编辑目录第一章前言 1 选题的目的 1 题目的意义 1 第二章冲压的基本知识 1 冲压的基本工序 1 冲压加工...
