汽车侧围a柱支撑板连接板冷冲模具设计论文-本科学位论文

结论本文介绍了汽车覆盖件模具中拉延模的设计。最后，说下本设计特点：将冲压工艺CAE与模具CAD进行集成化，即一方面采用CAD系统为有限元模拟建立几何模型，另一方面采用CAE分析结果对CAD设计结果进行评价，提供改进信息，优化工艺参数和模具结构，提高了模具设计质量。在整个设计过程中，创造性地综合运用过去几年所学的知识，有目的地学习当前模具领域的新技术并运用在本设计当中，完成了本专业一个具体的设计任务。进一步巩固所学知识、加深和拓宽了知识面，培养和锻炼了分析问题和解决问题的能力，提高了自主学习精神。参考文献参考文献[1]《冲压工艺及冲模设计》翁其金徐新成机械工业出版社2006.2[2]《现代模具技术》编写委员会.汽车覆盖件模具设计与制造.xx：国防工业出版社，1998.1[3]涂光祺等．冲模技术．xx：机械工业出版社，2002．8[4]黄亚娟等．CAD／CAE／CAM技术在汽车覆盖件模具中的应用与发展.机电工程技术，204年第33卷第5期.13～15[5]孙凤勤．冲压与塑压设备.xx：机械工业出版社，1997.10[6]肖景容、姜奎华主编《冲压工艺学》，机械工业出版社2002.8[7]曾向阳，谢国明，王学平等著.UGNX基础及应用教程.xx：电子工业出版社，2003.1[8]武晓红．日本冲压模具的技术特点．模具技术．2001（1），49~52[9]居襄等．汽车车身板料冲压成形分析与模拟．汽车工程．1996（4），249~256[10]曹颖等．拉伸／收缩翻边过程的修边线预示．工程力学．2001（4），35~40[11]谢红等．UG—Ⅱ计算机软件在冲压模具设计中的应用．机械设计与制造．2000（4），18~19[12]F.-K.ChenandY.-C.Liao．AnAnalysisofDraw-WallWrinklinginaStampingDieDesign．IntJAdvManufTechnol(2002)19:253–259[13]姜奎华主编《冲压工艺与模具设计》，机械工业出版社2002.3[14]何玉林等．机械制图．重庆：重庆大学出版社，2000．8[15]邓文英等．金属工艺学．xx：高等教育出版社，2001．1[16]廖念钊等．互换性与技术测量．xx：中国计量出版社，2000．1[17]王新华、袁联富编，《冲模结构图册》，机械工业出版社；[18]薛启翔等编，《冲压模具设计制造难点与窍门》，机械工业出版社；[19]冲模设计手册编写组，《冲模设计手册》，机械工业出版社；[20]模具实用技术丛书编委会主编《冲模设计应用实例》，机械工业出版社参考文献[21]中国模具设计大典编委会，《中国模具设计大典》电子版[22]《最新冲压新工艺新技术及模具设计实用手册》电子版［23］《冷冲压模具设计指导》，王芳主编。机械工业出版社，1998.10附录附录附录一：外文文献Modernfasteconomymanufacturemoldtechnology1introductionAlongwiththeglobaleconomydevelopment,thenewtechnologicalrevolutionmadethenewprogressandthebreakthroughunceasingly,thetechnicalleapdevelopmentalreadybecomestheimportantattributewhichtheimpetusworldeconomicsgrew.Themarketeconomyunceasingdevelopment,urgestheindustryproductmoreandmoretothemulti-varieties,highgrade,thelowcostdirectiontodevelop,inordertomaintainandstrengthenstheproductinmarketcompetitivepower,productdevelopmentcycle,productioncyclemoreandmoreshort,thereupontomakeseachkindofproducttheessentialcraftequipmentmoldrequesttobemoreandmoreharsh.Ontheonehandtheenterpriseforthepursuescalebenefit,causesthemoldtoturntowardshighspeed,isprecise,thelonglifedirectiondevelops;Ontheotherhandenterpriseinordertosatisfythemulti-varieties,,theproductrenewalquickly,winsthemarkettheneed,requeststhemoldtoturntowardsthemanufacturecycletobeshort,thecostlowfasteconomydirectiondevelops.Thecomputer,thelaser,electronic,thenewmaterial,thenewtechnicaldevelopment,causesthefasteconomicalpatternmakingtechnologyevenmorepowerful,theapplicationscopeexpandsunceasingly,thetypeincreasesunceasingly,thecreationeconomicefficiencyandthesocialefficiencyaremoreandmoreremarkable.2fasteconomicalpatternmakingstechnologiestypeThefasteconomicalpatternmakingtechnologyandthetraditionalmachine-finishingcompares,hasthepatternmakingcycleshort,thecostislow,theprecisionandthelifecansatisfyintheproductiontheoperationrequirements,issynthesizesaneconomicefficiencyquiteremarkablekindtomakethemoldthetechnology,summarizesbelow,hasseveraltypestoleave.附录2.1fastprototypesmanufacturestechnologyThefastprototypemanufacturetechnologyiscalledRPM,isonekindofnewmanufacturetechnologywhichthe80'slaterperioddevelops.US,Japan,England,Israel,Germany,Chinahaveallpromotedowncommercializationproduct,andhasformedthenewindustrygradually.RPMisthecomputer,thelaser,theopticalscanning,theadvancednewmaterial,thecomputer-aideddesign(CAD),thecomputerassistanceprocessing(CAM),thenumericalcontrol(CNC)synthesizestheapplicationthehightechnologyandnewtechnology.Intakesshapeintheconcepttaketheplaneseparate,pilesupastheinstruction,inthecontroltakethecomputerandthenumericalcontrolasthefoundation,takebiggestflexibilityasgeneralgoals.Ithasabandonedthetraditionalmachine-finishingmethod,tothemanufacturingindustrytransformationisasignificantbreakthrough,usestheRPMtechnologytobepossibledirectlyorindirectlythefastpatternmaking,thistechnologyalreadybyprofessionwidespreadapplicationandsoonautomobile,aviation,electricalappliances,ships,medicalservice,mold.Undersummarizedalreadycommercializationseveralkindofmodelsfasttotakeshapeatpresentthecraft.2.1.1lasersthree-dimensionalphotoetchingtechnology(SLATheSLAtechnologyhandsoverthecomputerCADmodellingsystemtoobtaintheproductthethree-dimensionalmodel,throughthemicrocomputercontrollaser,accordingtothedeterminationpath,iscarryingontotheliquidstatephotosensitiveresinbythelevelscanning,causeslayeruponlayertosolidifybythescannedsector,isunitedasonebody,formsthefinalthreedimensionalentity,afteragainpassesthroughtherelatedfinallyhardeningtopolishandsoonplacethequantity,formstheworkpieceorthemold.Thelaserthree-dimensionalphotoetchingtechnologymaincharacteristicismaytakeshapewilfullythecomplexshape,takesshapetheprecisionhigh,simulationstrong,materialusefactorhigh,performancereliable,theperformancepricequiteishigh.Suitstheproductoutlooktoappraise,thefunctionexperiment,fastmakestheelectrodeandeachkindoffasteconomicalmold.Butthistechnologyusesequipmentandphotosensitiveresinpriceexpensive,causesitscosttobehigh.2.1.2packoflevelsoutlinesmanufacturetechnology(LOM)TheLOMtechnologyisthroughthecomputerthree-dimensionalmodel,theuselaserselectivelytoitslaminationslice,willobtaineachsectionoutlinelayeruponlayerwillcake,finallywillfoldtheadditionthreedimensi
