带凸缘圆筒形件拉深模设计

I摘要随着中国工业不断地发展，模具行业也显得越来越重要。本文针对带凸缘圆筒形零件的拉伸工艺性及拉伸工序过程，列举其中一次拉深并完成模具设计。介绍了筒形零件冷冲压成形过程，经过对筒形零件的批量生产、零件质量、零件结构以及使用要求的分析、研究，按照不降低使用性能为前提，将其确定为冲压件，用冲压方法完成零件的加工，且简要分析了坯料形状、尺寸，排样、裁板方案，拉深次数，冲压工序性质、数目和顺序的确定。进行了工艺力、压力中心、模具工作部分尺寸及公差的计算，并设计出模具。同时具体分析了模具的主要零部件的设计，冲压设备的选用，凸、凹模间隙调整。列出了模具所需零件的详细清单，并给出了合理的装配图。关键词冲压件/带凸缘圆筒形拉伸件/拉伸工艺/拉深模设计WITHFLANGECYLINDRICALDEEPDRAWINGDIEDESIGNIIABSTRACTAsChina'sindustrialdevelopmentunceasingly,themoldindustryalsoappearsmoreandmoreimportant.Thispaperbeltofflangecylindricalpartsstretchingmanufacturabilityandstretchingprocessprocess,listonetimedeepdrawingandcompletethemolddesign.Coldstampingprocessofcylindricalpartsisintroduced,aftermassproductionofthecylindricalparts,partsquality,partsstructure,anduserequirementanalysis,research,accordingtonotreducetheusabilityforthepremise,toidentifyitforstampingparts,completepartsprocessing,withstampingmethodandthebriefanalysisoftheblankshape,size,layout,cuttingboard,deepdrawing,stampingprocessinnature,thedeterminationofnumberandorder.Thetechnologyforce,pressurecenter,moldworkingpartsdimensionandtoleranceofcalculation,anddesignthemold.Atthesametime,concreteanalysisofmaincomponentsofthemolddesign,theselectionofstampingequipment,convexandconcavedieclearanceadjustment.Liststhemouldneedsadetailedlistofspareparts,andgivesthereasonableassemblydrawing.KEYWORDSstampingparts,flangecylindricalstretching,stretching,deepdrawingdiedesignprocess目录1前言...........................................................................................................................................1III1.1模具的概论.................................................................................................................11.1.1冲压与冲模...........................................................................................................11.1.2我国冲压现状与发展方向...................................................................................21.1.3国外模具发展趋势及行业特点...........................................................................21.1.4模具设计及加工技术的现状...............................................................................31.1.5冲模分类...............................................................................................................41.1.6冲模的零部件.......................................................................................................41.2冲压件工艺分析........................................................................................................51.2.1冲压加工的经济性分析.......................................................................................51.2.2冲压件的工艺性分析...........................................................................................51.3本设计要求.................................................................................................................62工艺方案..................................................................................................................................72.1工艺性分析.................................................................................................................72.1.1拉深件的结构与尺寸...........................................................................................72.1.3拉深件材料............................................................................................................72.2设计方案的确定........................................................................................................73主要工艺参数计算...............................................................................................................83.1确定排样、裁板方案...............................................................................................83.1.1工艺分析...............................................................................................................83.1.2确定修边余量.......................................................................................................83.1.3坯料直径...............................................................................................................83.1.4排样.......................................................................................................................93.1.5压力中心的确定.................................................................................................103.2拉深工艺的计算......................................................................................................103.2.1压边.....................................................................................................................103.2.2总拉深系数.........................................................................................................103.2.3预算拉深次数.....................................................................................................103.2.4确定首次拉深工序件尺寸.................................................................................113.2.5确定拉深次数及以后各次拉深的工序件尺寸.................................................123.2.6第二次拉深直径和高度.......................................................................................133.2.7第三次拉深直径和高度.................................................
