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：1.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。2.同时对所设计的模具分别进行了分析说明，3.对压力机做出了合理的选择，4.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。关键字：冲压模；空气滤清器壳；冲裁间隙；冲压工艺。Abstract:Boardmaterialcoldtopress,itprocessestobemachinedoneimportantcomponent.Itisveryextensivethatitemploys.Butbecausethechoicewithunreasonablechoiceandpressingtheintervalthattraditionalprocessingispressingthecraftschemeistoobig,questionofmatchingofthepress.etc.ThistextpressesTheautomobilerimfallsthemateraldrawingcompoundmoldwiththemainintroductionofmolddesigntotheclutchhousing:1.Calculatebyanalysis,craftbycraft,intervalchoiceofvalue,confirmthisdesigntechnologicalprocessandstructuralformoftrimmingdie.2.Analyzedseparatelytomouldsdesignedthatexplainatthesametime,3.Havingmadetherationalchoicetothepress,4.ThewholecourseadoptsAutoCADsoftwaretodrawthetwo-dimentionalinstallationdiagramsandspecificpartpicturesofthemould.Keyword:Pressthemould；automobilerim；theintervalofblanking；pressthecraft。1目录1前言.........................................................................................................................................................................41．1冲压技术概述...............................................................................................................................................41．2冲压技术的发展趋势...................................................................................................................................52冲压工艺分析.........................................................................................................................................................62．1零件材料的分析...........................................................................................................................................62．2零件工艺性能分析.......................................................................................................................................62．3确定工艺方案与模具形式...........................................................................................................................62．4冲压工序数确定...........................................................................................................................................72．5模具类型的确定...........................................................................................................................................82．6工艺方案分析...............................................................................................................................................83模具结构型式的确定..........................................................................................................................
