文档介绍:. 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。本设计是空气滤清器壳反拉深、冲孔复合模设计,冲模的结构性能直接反映了冲压技术水平的高低。选用材料时应考虑模具的工作特性,受力情况,冲压件材料性能,冲压件的精度,生产批量以及模具材料的加工工艺性能和工厂现有条件等因素。冲床的选用主要是确定冲床的类型和吨位。板料冷冲压加工是机械加工的一个重要组成部分。它应用十分广泛。但由于传统的加工存在着冲压工艺方案选择不合理、冲压间隙选择过大,压力机不相匹配等问题。本文就以空气滤清器壳反拉深、冲孔复合模设计主要介绍了冲压模具设计的全过程: ,间隙值的选择,确定了该设计工艺流程及冲模结构形式。 , , AutoCAD 软件绘制模具的二维装配图和个别零件图。关键字:冲压模; 空气滤清器壳;冲裁间隙;冲压工艺。 Abstract : Board material cold to press , it processes to be machined one ponent. It is very extensive that it employs . But because the choice with unreasonable choice and pressing the interval that traditional processing is pressing the craft scheme is too big, question of matching of the press. etc. This text presses The automobile rim falls the materal pound mold with the main introduction of mold design to the clutch housing: 1. Calculate by analysis , craft by craft, interval choice of value, confirm this design technological process and structural form of trimming die. 2. Analyzed separately to moulds designed that explain at the same time , 3. Having made the rational choice to the press, 4. The whole course adopts AutoCAD software to draw the two-dimentional installation diagrams and specific part pictures of the mould . Key word: Press the mould ; automobile rim ; the interval of blanking ; press the craft 。. 目录 1 前言....................................................................................................................................................................... 4 冲压技术概述............................................................................................................................................. 4 冲压技术的发展趋势................................................................................................................................. 5 2 冲压工艺分析....................................................................................................................................................... 6 零件材料的分析....
