江苏大学本科毕业论文I制动缸前盖拉深工艺及模具设计摘要冲压成形作为现代工业中一种十分重要的加工方法,用以生产各种板料零件,具有很多独特的优势,是一种其它加工方法所不能相比和不可替代的先进制造技术。在制造业中具有很强的竞争力,被广泛应用于汽车、能源、机械、信息、航空航天、国防工业和日常生活的生产之中。因此,研究冲压成形具有很重要的意义。本文以制动缸前盖为对象,设计中涉及落料拉深模、整形模、冲孔模。通过使用CAD和UG等软件绘画出所设计的零件,从而确定其形状和尺寸。对制动缸前盖的工艺性进行分析,计算其毛坯尺寸、修边余量等等,选择拉深方法,确定制动缸前盖工艺方案。在设计落料拉深模、整形模、冲孔模时。首先,对其进行工艺分析和理论计算,如:对于落料首次拉深模,进行拉深系数和拉深次数的计算,确定拉深工艺;计算冲裁力和拉深力,选取压力机;计算拉深间隙等。然后对模具进行各零件的设计,如:凸凹模、卸料板、定位销、导柱导套等等,分析各零件的作用和工作方式,再通过计算和查资料确定零件的尺寸和样式,利用CAD画出其二维图,并在图上标明尺寸。选择模具结构(根据零件图样及计算要求,结合生产实际情况,提出模具结构方案分析比较,选择最佳结构)其次,分析各零件的工作过程,根据其所需性能(如:耐磨性能),选取各零件的材料,并制定对于各零件的材料采用的热处理工艺。最后,整合模具所有零件,分析确认其装配位置,画出模具总装图,并在图上指出各零件的名称。关键词制动缸前盖拉深整形冲孔模具江苏大学本科毕业论文IIDeepdrawingprocessanddiedesignofthebrakecylinderfrontcoverAbstractStampingasaveryimportantmodernindustrialprocessingmethodsfortheproductionofavarietyofsheetmetalparts,hasmanyuniqueadvantages,isoneoftheotherprocessingmethodscannotbecomparedandirreplaceableadvancedmanufacturingtechnology.Inthemanufacturingsectorhasastrongcompetitiveedge,hasbeenwidelyusedinautomotive,energy,machinery,information,aerospace,defenseindustryandtheproductionofeverydaylifeamong.Therefore,thestudystampinghasveryimportantsignificance.Inthedesignofblankingdrawingdie,plasticmold,punchingmold.First,itsprocessanalysisandtheoreticalcalculations,suchas:Forthefirsttimeblankingdrawingdiefordrawingdrawingcoefficientandthenumberofcalculationstodeterminethedeepdrawingprocess;calculatedpunchingforceanddrawingforce,selectthepresses;drawingandgapcalculation.Theneachpartofthemolddesign,suchas:punch,stripperplate,pins,guidepinsandbushings,etc.,analyzingeachpartoftheroleandwork,thenchecktheinformationdeterminedbycalculatingandpartsofsizesandstyles,useofCADdrawthetwo-dimensionalmap,andmarkedonthegraphsize.Selectthemoldstructure(partsdrawingsandcalculationsbasedonrequirements,combinedwiththeactualproductionsituation,putforwardthemoldstructureanalysisandcomparisonofprogramstochoosethebeststructure)Secondly,theanalysisofthevariouspartsoftheworkprocess,accordingtotheirrequiredperformance(eg:wearresistance),Selecteachpartofthematerial,andtodevelopmaterialsusedforeachpartoftheheattreatmentprocess.Finally,theintegrationofallpartsofthemold,analysisconfirmsitsassemblyposition,drawthemoldassemblydiagramsandchartsindicatethenameofeachpart.KeywordsBrakecylinderfrontcoverdrawingplasticpunchingdie江苏大学本科毕业论文III目录摘要...............................................................IAbstract..........................................................II第一章绪论..............................................11.1引言........................................................11.2冲压技术发展的特征..........................................11.3冲压成形技术的发展及趋势.....................................21.3.1冲压技术的发展.........................................21.3.2冲压技术的发展趋势.....................................31.4冲压在生产生活中的应用.......................................4第二章制动缸前盖的工艺分析及工艺方案选取................62.1制动缸前盖的工艺性分析及计算.................................62.1.1制动缸前盖的工艺分析...................................62.1.2拉深方法的选择.........................................82.1.3确定修边余量..........................................102.1.4毛坯展开尺寸..........................................102.2制动缸前盖工艺方案确定......................................10第三章制动缸前盖落料首次拉深模的设计...................123.1制动缸前盖落料首次拉深模工艺分析及理论计算..................123.1.1拉深系数和拉深次数的确定..............................123.1.2冲裁力和拉深力的计算及压力机的选择....................133.1.3冲裁件的排样..........................................143.2落料首次拉深模工作零件的设计................................153.2.1凸凹模间隙的确定......................................153.2.2凸凹模工作尺寸的确定..................错误!未定义书签。3.2.3圆角半径的确定........................................173.2.4材料的选取及热处理....................................183.3落料首次拉深模定位零件的设计................................183.3.1定位销的设计..........................................183.3.2导料销的设计..........................................193.4落料首次拉深模其他零件的设计................................193.4.1模架与导向零件的设计..................................193.4.2卸料板的设计..........................................213.4.3磨柄、推杆、推件器、螺钉的选择........................213.4.4其他零件的材料选用及热处理............................223.5制动缸前盖落料首次拉深模总装图..............................23第四章制动缸前盖整形模的设计...........................244.1制动缸前盖整形模的分析及计算................................24江苏大学本科毕业论文IV4.1.1整形力的计算..........................................244.1.2压力机的选取..........................................244.2制动缸前盖整形模凸凹模的设计................................244.2.1凸凹模尺寸确定........................................244.2.2凸凹模形状和尺寸......................................254.3其他零件的设计..............................................254.3.1导向和定位零件设计....................................254.3.2卸料的设计............................................254.4材料的选择及热处理..........................................254.5制动缸前盖整形模总装图......................................26第五章制动缸前盖冲孔模的设计...........................275.1制动缸前盖冲孔模的工艺分析及理论计算........................275.1.1冲裁力的计算..........................................275.1.2压力机的选择..........................................275.2冲孔模凸凹
