汽车备轮架加固板冲压工艺模具结构设计 摘 要：随着我国改革开放步伐的进一步加快，作为制造业基础的模具行业近年来得到了迅速发展。机械、电子、汽车、石化、建筑，都要求模具工业的发展与之相适应。模具生产水平的高低，己成为衡量一个国家产品制造水平高低的重要标志，在很大程度上决定着产品的质量、效益和新产品的开发能力。Motor-round Reinforcement Plate by Stamping Process Die Structure Design Abstract：As Chineses reform and opening up the pace to accelerate further, as a manufacturing base of the mold industry has been developing rapidly in recent years. Machinery, electronics, automotive, petrochemical, construction, require the development of industries die with suitable. Die high and low levels of production, has become a country to measure the level of manufacturing an important indicator, to a large extent determine the quality, effectiveness and capability to develop new products. The graduation project is stamping die in car on the typical application. This paper first analysis of the current prospects for the development of the industry mold and then sum up the basic steps to mold design; combined with the issue of mold design of the programme, the basic calculation of a detailed explanation. Key words：Molding tool、Craft project、Fall to anticipate、Blunt bore、Flexion 目 录 摘要…………………………………………………………………………………………………1 目录…………………………………………………………………………………………………2 1 前言……………………………………………………………………………………………42 总体方案设计…………………………………………………………………………………5 2.1 调查研究……………………………………………………………………………………5 2.2 工艺方案的拟订……………………………………………………………………………5 2.2.1 零件的分析………………………………………………………………………………5 2.2.2 制订工艺路线……………………………………………………………………………63 各工序模具结构形式的确定…………………………………………………………………10 4 计算各工序冲压力和选择冲压设备 ………………………………………………………13 4.1 第一道工序——落料………………………………………………………………………134.1.1?平刃口模具冲裁………………………………………………………………………134.1.2 斜刃口模具冲裁……………………………………………………………………13 4.2 第二道工序——冲孔………………………………………………………………………14 4.2.1 冲孔力计算……………………………………………………………………………14 4.3 第三道工序——首次弯曲成形……………………………………………………………14 4.3.1 自由弯曲力计算………………………………………………………………………14 4.3.2 校正弯曲力 ……………………………………………………………………………14 4.3.3 压料力计算……………………………………………………………………………15 4.3.4 选择冲压设备………
