控制机构固定板冷冲模设计摘要：本设计为一固定板的冷冲压模具设计，根据设计零件的尺寸、材料、批量生产等要求，首先分析零件的工艺性，确定冲裁工艺方案及模具结构方案，然后通过工艺设计计算，确定排样和裁板，计算冲压力和压力中心，初选压力机，计算凸、凹模刃口尺寸和公差，最后设计选用零、部件，对压力机进行校核，绘制模具总装草图，以及对模具主要零件的加工工艺规程进行编制。其中在结构设计中，主要对凸模、凹模、凸凹模、定位零件、卸料与出件装置、模架、冲压设备、紧固件等进行了设计，对于部分零部件选用的是标准件，就没深入设计，并且在结构设计的同时，对部分零部件进行了加工工艺分析，最终才完成这篇毕业设计。关键词：模具；冲裁件；凸模；凹模；凸凹模；AbstractThedesignforaplateofcoldstampingdiedesign,accordingtothesizeofthedesigncomponents,materials,massproduction,etc.,thefirstpartoftheprocessofanalysistodeterminetheblankingprocessplanninganddiestructureoftheprogram,andthenthroughtheprocessdesigncalculations,determinethenestingandcuttingboard,calculatethepressureandpressurewashedcenters,primarypresses,computingconvexandconcaveDieCuttingEdgedimensionsandtolerances,thefinaldesignselectionofpartsandcomponents,topressforchecking,drawingdieassemblydrawings,aswellasMoldprocessingtechnologyofthemainpartstothepreparationprocedures.Inwhichthestructuraldesign,primarilytothepunchanddie,punchanddie,positioningparts,unloadingandoutofpiecesofequipment,mold,pressingequipment,fasteners,etc.hasbeendesigned,fortheselectionofsomecomponentsarestandardparts,thereisnoin-depthdesign,andstructuraldesign,whilesomepartsfortheprocessingprocessanalysisandultimatelytocompletethisgraduationproject.Keywords:mold;stampingparts;punch;die;punchanddie;目录一、前言..........................................................................4冲裁模设计题目....................................................................7二、零件的工艺分析...............................................................82.1结构与尺寸...................................................................82.2精度.........................................................................82.3材料.........................................................................8三、确定冲裁工艺方案..............................................................9(a)先落料，再冲孔，采用单工序模生产；.............................................9(b)采用落料——冲孔复合冲压，采用复合模生产；.....................................9(c)用冲孔——落料连续冲压，采用级进模生产。.......................................9四、确定模具总体结构方案.........................................................104.1模具类型....................................................................104.2操作与定位方式..............................................................104.3卸料与出件方式..............................................................104.4模架类型及精度..............................................................104.5凸模设计....................................................................10五、工艺设计计算.................................................................115.1排样设计与计算..............................................................115.2计算冲压力与压力中心，初选压力机............................................125.3计算凸、凹模刃口尺寸及公差..................................................13六、设计选用零件、部件，绘制模具总装草图.....................................
