模具毕业设计论文

**理工大学毕业设计（论文）I轴碗冲压模具设计摘要冲压模具在实际工业生产中应用广泛。在传统的工业生产中，工人生产的劳动强度大、劳动量大，严重影响生产效率的提高。随着当今科技的发展，工业生产中模具的使用已经越来越引起人们的重视，而被大量应用到工业生产中来。冲压模具的自动送料技术也投入到实际的生产中，冲压模具可以大大的提高劳动生产效率，减轻工人负担，具有重要的技术进步意义和经济价值。本文提出采用模具来生产止动件的新工艺，并针对某规格夹具止动件设计了复合模。该模具设计的难点主要是如何解决好零件中的孔冲裁、确定模具结构、如何进行模具的制造及冲裁方案选定等。本文结合止动件的特点，具体解决了压力机的选择与校核、凸模和凹模刃口尺寸计算及结构设计、定位方案设计、卸料方式的设计、主要模具零件的加工工艺、标准零件的选用、模具的装配等一系列的设计工作，这些设计可为类似的零件模具设计提供现实的指导意义。此次模具设计的突出特点是尝试使用复杂的复合模具，解决常规冲压工艺模具套数多、工艺路线长、生产成本高、效率低等缺点，并为以后此类零件冲压工艺的编制及模具设计提供了可靠的依据。本文介绍的模具实例结构简单实用，使用方便可靠，对类似工件的大批量生产具有一定的参考作用。关键词：冲模，复合模，冲裁力，冲裁间隙**理工大学毕业设计（论文）IIAxisbowlstampingdiedesignABSTRACTPunchingdiehasbeenwidelyusedinindustrialproduction.Inthetraditionalindustrialproduction,theworkerworkveryhard,andtherearetoomuchwork,sotheefficiencyislow.Withthedevelopmentofthescienceandtechnologynowadays,theuseofpunchingdieintheindustialproductiongainmoreattention,andbeusedintheindustrialproductionmoreandmore.Self-actingfeedtechnologyofpunchingdieisalsousedinproduction,punchingdiecouldincreasetheefficienceofproductionandcouldalleviatetheworkburden，soithassignificantmeaningintechnologicprogressandeconomicvalue.ThisArticleproposesusingmoldtoproduceretainerofthenewtechnology,Andagainstastandardfixtureretainerdesignofthecompounddies.Themainproblemsofthismolddesignishowtosolveretainerofpunchingholes,determinemoldstructure,howtomanufacturingthemoldandselectedblankingprogramsandsoon.ThisArticleCombinethecharacteristicsofretainer,concretelysolvethechoiceandverifycheckofthepressmachine,thenumerationandstructuredesignofthepointdimensionofpunchandmatrix,thelocatingprojectdesign,themethodofstripper,themainmoldpartsprocessing,thechoiceofstandardparts,thedesignofthemodelassemble.Butthecharacteristicsofthedesignistotrytousingthecomplicatedies.Tosolvetheproblemoforiginalprocess,suchaslargenumbersofdie,longprocessoftechnology,highproductioncost,lowefficiency,difficultyinkeepingsymmetryofworkingpartsaresolved,andareliableevidencefortheworkoutofstampingprocessanddiedesignofthesepartsisprovided.KEYWORDS:punchingdie,compounddies,blankingforce,blankingdearance**理工大学毕业设计（论文）III目录前言................................................................................................1第1章绪论......................................................................................21.1模具行业................................................................................21.2国内外模具发展状况及趋势.................................................21.3本次设计的主要方向、内容及目的.....................................3第2章冲压工艺与模具设计...........................................................52.1冲压件工艺分析...................................................................52.2工艺方案及模具结构类型...................................................52.3排样及搭边...........................................................................62.4冲压力与压力中心计算.......................................................72.4.1冲压力.......................................................................72.4.2压力中心...................................................................82.5工作零件刃口尺寸计算.....................................................102.5.1刃口尺寸确定的原则..............................................102.5.2刃口尺寸确定的方法..............................................102.6工作零件结构尺寸.............................................................112.6.1落料凹模尺寸..........................................................112.6.2冲孔凸模尺寸..........................................................122.7其它模具零件结构尺寸及模架选用..................................122.8压力机的规格选用.............................................................132.9模具装配图.........................................................................142.10零件技术要求...................................................................14第3章模具制造...........................................................................183.1其余模具标准零件.............................................................183.1.1固定挡料销及导料销..............................................183.1.2推杆.........................................................................183.1.3防转销.....................................................................193.1.4圆柱销.....................................................................20**理工大学毕业设计（论文）IV3.1.5卸料螺钉.................................................................203.1.6内六角圆柱头螺钉..................................................213.1.7模柄.........................................................................223.1.8卸料弹簧.................................................................233.1.9导柱导套.................................................................243.1.10模座.......................................................................24第4章模具装配与调试...............................................................264.1模具装配特点.....................................................................264.2装配技术要求.....................................................................264.3装配过程.............................................................................274.3.1常用的装模工具...................................
