毕业设计说明书简单冲裁模具设计学生姓名：学号：学院：示范性软件职业技术学院专业：模具设计与制造指导教师：2009年6月简单冲裁模具设计摘要本次我设计的是简单冲裁模具。因为本次设计题目与实践结合紧密，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，确定压力机的型号。再分析对冲压件加工的模具适用类型选择所需设计的模具。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。在本次设计中采用了冲孔、切断级进模。该模具的特点是在排样过程中不用考虑搭边值，板料宽度与零件宽度一致，节约材料。同时简化了步骤，提高了工作效率。关键词：冲压，冲孔，落料，压力机SimpleBlankingDieDesignAbstractIdesignedthissimpleblankingdies.BecausethedesignoftheclosecombinationofTitleandPractice,afteraccesstoinformation,thefirstpartstotheprocessanalysis,throughprocessanalysisandcomparison,theuseofpunchblankingprocess,throughtheblankingforce,thetoppiece,andintermsofdischargepower,todeterminethemodelpress.Furtheranalysisofthestampingdiesforprocessingtheapplicationtoselectthedesiredtypeofmolddesign.Themoldwillbedesignedtodrawuponthetypeoftheworkingpartsofthemolddesignprocesstoexpress.Inthisdesigntheuseofthepunching,progressivedieoff.Thecharacteristicsofthemoldareintheprocessofpackingupsidewithoutconsideringthevalueofsheetwidthandthewidthofthesameparts,savingmaterial.Atthesametimesimplifyingthestepstoimprovetheworkefficiency.Keywords:Stamping,Punching,Blanking,Press中北大学2009届毕业设计说明书目录1引言...................................................................12冲裁模具的工艺分析.....................................................22.1冲裁件工艺分析......................................................22.2工艺方案的确定......................................................22.3冲裁变形过程........................................................32.4冲裁间隙............................................................33模具设计的计算.........................................................53.1排样................................................................53.2搭边值的确定........................................................53.3条料宽度的确定......................................................63.4材料利用率的计算....................................................73.5冲压力计算..........................................................73.5.1冲裁力...........................................................73.5.2冲孔力...........................................................83.5.3冲裁时的推料力...................................................83.5.4冲压力的计算:....................................................83.6确定模具压力中心....................................................93.7冲模刃口尺寸及公差..................................................93.7.1冲孔部分.........................................................93.7.2落料部分........................................................113.8各主要零件结构尺寸的确定...........................................123.8.1凹模外形尺寸的确定..............................................123.8.2凸模长度LP的确定................................................123.9定位零件...........................................................134冲压设备选取..........................................................145模具的装配............................................................155.1设计并绘制总图、...
