青岛理工大学2010材料成型及控制工程大丸子2014.1.2I摘要本文介绍的模具实例结构简单实用，使用方便可靠，首先根据工件图算工件的展开尺寸，在根据展开尺寸算该零件的压力中心，材料利用率，画排样图。根据零件的几何形状要求和尺寸的分析，采用复合模冲压，这样有利于提高生产效率，模具设计和制造也相对于简单。当所有的参数计算完后，对模具的装配方案，对主要零件的设计和装配要求技术要求都进行了分析。在设计过程中除了设计说明书外，还包括模具的装配图，非标准零件的零件图。本套模具包括落料冲孔复合模和弯曲模两套模具，在模具的结构设计和计算完成后，开始利用UGNX建模模块下设计模具的每个零件图，如上、下模座，上、下垫板，凸、凹模等，在零件的设计过程中需要利用UGNX的拉伸、旋转、扫掠、孔等各种功能，有利于我们熟悉UGNX的强大功能。之后在UGNX装配模块下再将零件装配。最后再利用UGNX将零件的三维图转换为二维图。关键词：模具复合模弯曲模冲压UGNXIIAbstractThistextintroductivemoldingtoolsolidexamplethestructureisinbriefpractical,theusageconvenienceisdependable,firstaccordingtotheworkpiecethediagramcalculatetheworkpiecetolaunchsize,ataccordingtolaunchthepressurecenterthatthesizecalculatesthatspareparts,thematerialutilization,paintingrowkinddiagram.Accordingtosparepartsofseveraltheshaperequestwiththeanalysisofthesize,adoptioncompoundthemoldhurtletopress,sobeadvantageoustoanexaltationproductionanefficiency,moldingtooldesignandmanufacturingalsooppositeinsimple.Whenallparametercalculationsareoverafter,requestedthetechniquerequeststothedesignandassembleofthemainsparepartstoallcarryonanalysistotheassembleprojectthatwhetstohave.Duringtheperiodofdesigninadditiontodesigningmanual,alsoincludetheassemblediagramofthemoldingtool,thesparepartsdiagramofthenot-standardspareparts,theworkpieceprocessesthecraftcard,thecraftrulesdistancecard,thenot-standardsparepartsprocessescraftprocesscard.Thissetofpunchdiesincludingblankingdieandbendingdietwosetsofcompositemold,inmolddesignandcalculationofthestructureiscomplete,startusingUGNXModelingtodesignthemoldforeachpartdrawing,above,underthemoldbase,thenextplate,convex,concavemold,thepartsofthedesignprocessneedtouseUGNXstretching,rotating,sweeping,holeandotherfeatureswillhelpusknowthepowerofUGNX.Finally,usingUGNXwillbepartofthethree-dimensionaldiagramintotwo-dimensionalmap.Keywords:mold,compounddie,bendingdie,stamping,UGNXIII目录摘要..........................................................................................................................IAbstract...................................................................................................................II目录......................................................................................................................III1前言.......................................................................................................................11.1本课题研究的意义...........................................................................................11.2研究本课题国内外的现状...............................................................................11.3本课题研究的主要内容...................................................................................22．冲裁零件工艺分析及工艺方案确定........................................................32.1弯曲件的工艺分析.......................................................................................................32.1.1结构与尺寸.........................................
