消声筒冲压工艺及模具设计
摘要
模具是工业生产中重要的工艺装备,是国民经济各部门发展的重要基础之一。复合模是一种复杂、精密的冲压模具,它具有高效率、高精度和高寿命等优越性,适用于各种冲压行业的自动化生产。复合模涉及冲压成形理论、冲压工艺、模具设计与制造以及模具材料中的许多关键技术。
本设计是针对汽车消声筒冲压模具的设计,设计先根据板件的结构特点及工艺特性进行工艺分析,再结合现今模具生产厂家的具体经验进行结构设计,切实将设计做到能够应用在实际生产中,使模具更具有实用性。
该工件结构特点适宜采用冷冲模进行生产,所以对冷冲压与模具的相关知识进行了简单介绍。拉申模是将经过落料工序的材料通过凸凹模的冲压产生塑性变形从而得到板件形状的工序,是模具中重要的组成部分是其他工序的基矗本设计对拉延模的工艺特点、组成、具体工作过程进行了阐述、并对组成模具的部分部件进行了分析。
