1、摘 要模具是制造业的重要工艺基础,在我国模具制造属于专用设备制造业。模具工业是汽车产品开发和大批量生产的重要组成部分。汽车前轴油封盖作为汽车的零部件之一,伴随着汽车业的高速发展,便要求快速的生产效率,及冲压得到的成品需要达到较高的精度以便满足所需的安全性能。以此为前提,分析其外形特征,需要完成落料拉深切边翻边冲孔,共五道工序才能成型。通过工艺性分析,确定了适合给定生产条件的最佳工艺方案,即落料拉深复合冲压、单工序切边冲压、翻边冲孔复合冲压的模具组合,共三副模具。本文分析了工件的冲压工艺性,确定零件的凸缘性质、拉深件的尺寸要求、拉深次数、切边余量,从而计算出毛坯尺寸,完成零件的排样设计;根据圆角
2、半径、凸凹模之间的间隙、尺寸公差,计算出凸、凹模刃口尺寸,确定凸模长度,凹模厚度;计算模具所需的冲压力,完成卸料装置、挡料销、顶出装置、推件装置的模具结构设计,以及压力机规格的选择;根据凸模、凹模的尺寸选择模架、导柱、导套、模柄、垫板、固定板;对每副模具的工作过程,模具的装配流程进行了详细的说明,并对模具的凸模、凹模、凸凹模的加工工艺进行了分析。根据分析计算得出的零件尺寸绘制了模具装配图和零部件图。完成零件的冲压工艺分析与模具设计。关键字:工艺分析;模具设计;绘制零件图AbstractMould is the important technical foundation of manufact
