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：
- 经工艺分析工艺计算，间隙值的选择，确定了该设计工艺流程及冲模结构形式。
- 同时对所设计的模具分别进行了分析说明，
- 对压力机做出了合理的选择，
- 整个过程采用AutoCAD软件绘制模具的二维装配图和个别零件图。

Abstract: Board material cold to press , it processes to be machined one important component. 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 drawing compound mold with the main introduction of mold design to the clutch housing:
- Calculate by analysis , craft by craft, interval choice of value, confirm this design technological process and structural form of trimming die.
- Analyzed separately to moulds designed that explain at the same time ,
- Having made the rational choice to the press,
- 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。
