广东工业大学华立学院本科毕业设计（论文）垫片冲裁模具设计论文题目垫片冲裁模具设计系部机电工程学部专业材料成型及控制工程班级2009级材料1班学号12020901013学生姓名何嘉潮指导教师2013年4月摘要模具是大批量生产同型产品的工具，是工业生产的主要工业装备。模具工业是国民经济的基础工业。而冲压模作为主要模具之一，更是在工业生产中有重要地位。而冲裁模则是冲压工艺中的基础工艺。冲裁模具可以保证冲压产品的尺寸精度，使产品质量稳定。而且在加工中不破坏产品表面。用冲裁模生产零件可以采用冶金厂大量的廉价的轧制钢板或钢带为材料，而且在生产中不需要加热，具有生产效率高，质量好，重量轻，成本低节约能源和原材料等一系列优点，是其他加工方法所不能比拟的。而本设计以垫片为研究对象，通过对制件的工艺分析，确定出垫片的三种冲压成形方案，最终选择级进模为最佳成形方案，并以此作为模具设计的依据。通过对制件外形的分析，确定斜排为最佳排样方式。本文对制件的冲裁力、凸凹模的刃口尺寸及外形尺寸进行了计算，根据计算所得的结果设计出了凸凹模的结构，并相应的设计出了凸凹模固定板、卸料板、导料板、挡料销、导正销等重要零件。根据冲裁力的大小选择合理的压力机并对其进行校核。利用CAD、Pro/e等软件绘制出模具的总装配图和工作零件图，最后确定模具制造过程中的加工工艺技术。关键词：冲压，垫片，排样，级进模，模具设计AbstractMoldstoformamassproductionofindustrialproductionfacilities,isthetechniquesandequipment.Moldindustryisthefoundationofthenationaleconomyindustry.Anddiepunching,asoneofthemainmolds,hasanimportantpositioninindustrialproduction.Thecuttingdieisthebasictechnologyofstampingprocess.Tooltoensureaccuracyoftheramoftheproductsizes,andmakeproductsquality.Andtheprocessofthesurfaceoftheproduct.Dieintheproductionofpartsofmetallurgicalfactoryofrolledsteelplatesorwithamaterial.Andinproductiondon’tneed,withhighefficency,quality,ligheweightandlowcosttosaveenergyandrawmaterialsforarangeofadvantages,isotherprocesscouldcomparewith.Thisdesign'sresearchobjectisgaskets,throughtheanalysisofthetechnologyoftheproductandmakingoutgasketsofthreekindsofstampingformingscheme,finalchoiceofprogressivedieforbestformingscheme,andusethisasthebasisformoulddesign.Throughtheanalysisoftheproductappearance,determinethestriplayoutinclinedrowofbestway.Thispapercalculatedoutcuttingforce,partsofthedieandpunchsizeandshapedimensionblade,accordingtothecalculationresultsdesignedstructureofdieandpunch,Andthecorrespondingdesignoutofthedieandpunchfixedboard,thestripperplateandguidematerialplate,blockmaterialpin,guidearesuchimportantpartssales.Accordingtothesizeofthecuttingforceandchoosingouttherationalpressingmachineandcarriesonthecheck.UsingCAD,Pro/esoftwaremapoutthetotaldrawingsandworkingmouldpartsgraph,thefinaldeterminationmouldmanufacturingprocessofprocessingtechnology.KEYWORDS:Stamping；Gasket；Packing；progressivedie；molddesign目录1绪论............................................................................................................................11.1冲压的概念、特点及应用..................................................................................11.2冲压技术的现状及发展方向..............................................................................21.3课题研究的意义..................................................................................................42冲压件的工艺分析及排样设计................................................................................52.1零件的结构、形状、精度分析..........................................................................52.2工艺方案的制定和选择......................................................................................52.3排样设计与计算..................................................................................................63冲压模具的工艺计算及结构设计............................................................................83.1冲裁力的计算......................................................................................................83.2模具压力中心的确定..........................................................................................93.3冲模刃口尺寸及公差的计算..............................................................................93.4凹模结构的设计................................................................................................113.5凸模结构的设计................................................................................................124模架及其他冲模零件的选择..................................................................................154.1主要模具零件的选择........................................................................................154.2选择紧固件及定位零件....................................................................................165模具总装配图和压力机的选择及校核..................................................................185.1模具总装配图....................................................................................................185.2模具工作原理....................................................................................................185.3压力机的选择....................................................................................................195.4压力机的校核....................................................................................................196冲压模具零件加工工艺的编制..............................................................................216.1上模座加工工艺过程........................................................................................216.2下模座加工工艺过程........................................................................................226.3凹模加工工艺过程............................................................................................236.4凸模加工工艺过程............................................................................................246.5凸模固定板的加工工艺过程............................................................................27总结...........................
