连接件多工位精密冲压模具设计 摘要 模具技术水平的高低是衡量一个国家制造业水平的重要标志之一，模具是高新技术产业的重要组成部分，是工业生产的基础装备。模具技术是一门综合性很强精密基础工艺装配技术，涉及新技术，新工艺，新材料，新设备的开发与推广应用；是冶金，材料，计量，机电一体化等多门学科以及铸造，锻造，热处理，机加工，检测等多工种共同打造的系统工程。用模具生产制品具有高效率，高一致性，高精度，高复杂性，低消耗等特点。模具制造业以成为与高新技术产业为依托的产业。 此次设计选用的工件为连接件，针对连接件做出了冲压模具设计。模具在我国被称之为“百业之母”，德国称之为“金属加工中的帝王”，有的国家甚至称之为印钞机；我相信我们的日常生活离不开他，模具会为其他行业奠定扎实的基础，也必将创造出属于他自己真实而又巨大的价值。 关键词：模具，工艺装配，高精度，连接件，冲压模具 ABSTRACT The level of mould tech
