安徽工程大学机电学院毕业设计(论文)-I-自行车脚蹬内板零件的冲压工艺及模具设计摘要本次毕业设计是在我们完成所有基础课和专业课以及课程设计的基础上开设的比较重要的教学实践环节,是对我们大学所学课程的巩固和重新认识,相信通过本次毕业设计,我们的水平可以有一定的提高。需要完成的主要工作有:对所给零件进行工艺性分析并确定合理的冲压工艺方案、进行有关工艺与设计计算、确定模具结构的设计及定位方式的选择、绘制零件的二维装配图并用三维软件进行运动仿真以验证和分析模具的工作过程。本次毕业设计是冲孔翻边落料级进模的设计,冲压模具主要是将板料分离或成形而得到制件的加工方法。因为模具的生产主要是大批量的生产,而且模具可以保证冲压产品的尺寸精度和产品质量,模具的设计与制造主要考虑到模具的设计能否满足工件的工艺性设计,能否加工出合格的零件,以及后来的维修和存放是否合理等。在本次设计中的自行车脚蹬内板中,不仅要考虑做出的零件能否满足工作要求,还要保证它的使用寿命。其次设计中还要考虑到它的实际工作环境和必须完成的设计任务,模架采用对角型模架,凹模采用组合凹模,这样可以采用线切割等数控设备来一次完成全部的工序加工,在设计中还要考虑到很多关于所设计模具的相关知识,包括它的使用场合、外观要求等,从这里可以知道模具设计是一项相对复杂的工作,所以在设计要不断的改进直到符合要求。关键词:翻边;工艺性;级进模梁超帝:自行车脚蹬内板零件的冲压工艺及模具设计-II-BicyclepedalwithintheboardpartsstampingprocessanddiedesignAbstractThequiteimportantteachingpracticelinkwhichthisgraduationprojectiscompletesallbasiccoursesandtheprofessionalcourseaswellasthecurriculuminuswhichdesigninthefoundationopens,isstudiesthecurriculumtoouruniversityconsolidatedandknew,believedthroughthisgraduationproject,ourlevelmayhavecertainenhancement.Needstocompletetheprimetaskincludes:Tocarriesonthetechnologycapabilitytothecomponentstoanalyzeandtodeterminethereasonablerammingcraftplan,carriesontherelatedcraftandthedesigncalculation,thedeterminationmoldstructuredesignandthelocatemodechoice,theplancomponentstwo-dimensionalassemblydrawingandcarriesonthemovementsimulationwiththethreedimensionalsoftwaretoconfirmandtoanalyzethemoldtheworkprocess.Thisgraduationispiercingflangingblankingprogressivediedesign,stampingdiemainlyformingsheetmetalseparationorgetpartsofprocessingmethod.Becausemoldproductionmainlyforhigh-volumeproduction,andmouldcanguaranteepressproductsfordimensionalaccuracyandqualityofproducts,toolingdesignandmanufactureofmajordesigncanmeetthework-pieceprocessdesign,whetherprocessingqualitypartsandlatermaintenanceandhostingisreasonable.Inthisdesignbikepedalinnerpanel,notonlytookintoaccountthemakepartscanmeetthejobrequirements,butalsotoguaranteethatitsservicelife.Second,designbutalsotoitsrealworldworkenvironmentanddesigntasksmustbecompleted,diewithdiagonaldie,diewithcombined,soyoucanwirecutting,CNCequipmenttocompletetheentireprocesswastotakeintoaccountthatmanyonthedesignofthemouldsofrelatedknowledge,includingitsappearancerequirementswhentheyareused,andsoon,fromhereyoucanlearnthemoulddesignisarelativelycomplexwork,tocontinuousimprovementuntilitmeetsyourrequirements.Keywords:theprocessofprogressivedie安徽工程大学机电学院毕业设计(论文)-III-目录第1章绪论............................................................................................................................1第2章零件的工艺性分析和工艺方案的确定....................................................................32.1零件的工艺性分析...........................................................................................................32.2冲裁工艺方案的确定.......................................................................................................32.3排样方案的确定及计算...................................................................................................4第3章主要工序力的计算....................................................................................................73.1翻边力的计算...................................................................................................................73.2冲裁力的计算...................................................................................................................93.3模具中主要尺寸的计算.................................................................................................11第4章模具设计..................................................................................................................164.1模具结构设计.................................................................................................................164.2定位方式的选择.............................................................................................................164.3卸料﹑出件方式的选择.................................................................................................174.4导向方式的选择.............................................................................................................17第5章模具的三维图绘制、装配与验证..........................................................................205.1绘制模具的三维零件图.................................................................................................205.2模具的三维装配图.........................................................................................................235.3对装配图进行运动仿真.................................................................................................25第6章模具的装配、调试和检测......................................................................................286.1模具的装配.....................................................................................................................286.2冲裁模具的调试.............................................................................................................286.3模具的检测.....................................................................................................................296.4模具材料的选用要求和选择原则............................................
