模具冲压设计-毕业(论文)设计论文.doc

论文题目：带缺圆形垫片冲压工艺及模具设计论文类型：应用设计专业：材料科学与工程摘要本次设计了一套冲孔﹑落料的模具。经过查阅资料，首先要对零件进行工艺分析，经过工艺分析和对比，采用冲孔落料工序，通过冲裁力、顶件力、卸料力等计算，确定模具的类型。得出将设计的模具类型后将模具的各工作零部件设计过程表达出来。在论文中第一部分，主要叙述了冲压模具的发展状况，说明了冲压模具的重要性，接着是对冲压件的工艺分析，完成了工艺方案的确定。第二部分，对零件排样图的设计，完成了材料利用率的计算。再进行冲裁工艺力的计算和冲裁模工作部分的设计计算，对选择冲压设备提供依据。最后对主要零部件的设计和标准件的选择，为本次设计模具的绘制和模具的成形提供依据。通过前面的设计方案画出模具各零件图和装配图。本模具性能可靠，运行平稳，能够适应大批量生产要求，提高了产品质量和生产效率，降低劳动强度和生产成本。关键词：冲压，落料冲孔模，模具结构Title:RoundgasketstampingprocesswithmissinganddiedesignMajor:MaterialsScienceandEngineeringName:DanZhaoSignature:Supervisor:Yu-JunZhangSignature:ABSTRACTAmoldingtoolfordesigningasetonlyhurtlingborefallinganticipating.Afteralotofaccesstoinformation,Punchingandblankingprocedurewereadoptedthroughprocessanalysis,punchingthrough,thetoppieces,suchasthedischargeofcalculationtodeterminethetypemold.Getamoldingtoolforwilldesigningtypeempressexpressesouteachworkzeropartsdesignprocessofthemoldingtool.Inthefirstpart,mainlydescribedthedevelopmentstatusofprogressivemetalstampingtools,illustratestheimportanceofstampingmould,thenthereistheprocessanalysisofstampingprocessscheme,completedthesure.FurtherblankingforcecalculationandDieDesignandcalculationofworkingpart.providethebasisfortheselectionofstampingequipment.Finallyonthemainpartsdesignandstandardfortheselectionofdesign,mouldofplottinganddieformingprovidesthebasis.Thedesignprojectpassingbeforedrawsaneachsparepartsofmoldingtooldiagramwithassemblethediagram.Themoldreliable,stableoperationtoadapttotherequirementsoflarge-scaleproduction,improveproductqualityandproductionefficiency.Reducelaborintensityandthecostofproduction.KERWOYDS:pressing，blankingandpiercingdie，diestructure目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc358452912"前言PAGEREF_Toc358452912\h1HYPERLINK\l"_Toc358452913"第1章冲裁工艺设计PAGEREF_Toc358452913\h5HYPERLINK\l"_Toc358452914"1.1设计任务PAGEREF_Toc358452914\h5HYPERLINK\l"_Toc358452915"1.2冲压工艺性分析PAGEREF_Toc358452915\h5HYPERLINK\l"_Toc358452916"1.2.1冲压件材料PAGEREF_Toc358452916\h5HYPERLINK\l"_Toc358
