編號無錫太湖學(xué)院畢業(yè)設(shè)計(jì)（論文）題目：基于CAD/CAM的復(fù)合沖壓模具設(shè)計(jì)信機(jī)系模具設(shè)計(jì)與制造專業(yè)學(xué)號：學(xué)生姓名：指導(dǎo)教師：（職稱：副教授）（職稱：）2013年5月25日摘要該論文主要研究了復(fù)合沖壓模具設(shè)計(jì)。通過對三個零件的工藝分析，制定出了模具設(shè)計(jì)方案，通過比較最終擇優(yōu)選出了復(fù)合沖壓模具。其中包括兩套沖孔落料復(fù)合模和一套拉深復(fù)合模以及一套單工序拉深模。通過對零件的分析，制定了合適的沖壓模設(shè)計(jì)工藝。該論文對每一副模具，經(jīng)過工藝分析、結(jié)構(gòu)設(shè)計(jì)，論證了其可能性，最終保證了制品的質(zhì)量。本論文具體分析了每副模具的總體結(jié)構(gòu)以及工作過程，對模具中的各個工作零件的設(shè)計(jì)原則、尺寸確定以及公差等做了具體的敘述。通過應(yīng)用三維軟件和CAD軟件進(jìn)行復(fù)合沖壓模具的數(shù)字化設(shè)計(jì),了解機(jī)械行業(yè)的先進(jìn)設(shè)計(jì)制造技術(shù)，掌握先進(jìn)的設(shè)計(jì)制造理念。此外，該論文還涉及了模具行業(yè)當(dāng)今的發(fā)展?fàn)顩r、發(fā)展水平、存在問題以及今后的發(fā)展前景等。由于模具的應(yīng)用領(lǐng)域越來越廣，其需求也越來越大，因此通過模具設(shè)計(jì)，可以更加熟悉模具的生產(chǎn)工藝。關(guān)鍵詞：復(fù)合沖壓模；工藝分析；三維軟件ABSTRACTThepapermainlystudiedthecompoundstampingdiedesign.Throughtheanalysisofthreepartstodevelopamolddesign,thenselectthefinalselectionofthebestcompoundstampingdiesbycomparing,includingtwosetsofpunchingblankingcompositemodulusandasetofdrawingcompositemodulusandasingleprocessdrawingdie.Developasuitablestampingdiedesignprocessbytheanalysisoftheparts.Thepapersanalyseseachmold,includestructuredesign,demonstratesthepossibilityoftheultimateguaranteeofthequalityoftheproducts.Inthisthesis,adetailedanalysisoftheoverallstructureandworkprocesspermoldfordeterminingthedimensionsandtolerances,andsodoaspecificdescriptionofthedesignprinciplesofthevariouspartsinthemold.Compoundstampingdiesthroughtheapplicationof3DsoftwareandCADsoftware,digitaldesign,advanceddesignandmanufacturingtechnologyofthemachineryindustry,tomastertheadvanceddesignandmanufacturingphilosophy.Inaddition,thepaperalsoinvolvesthedevelopmentofmoldindustryintodayslevelofdevelopment,thereareproblemsandfuturedevelopmentprospects.Increasinglywideareasofapplicationofthemold,itsdemandisalsoincreasing,sothemolddesign,moldproductionprocesscanbecomemorefamiliarwith.Keywords:Compoundstampingdie；ProcessAnalysis；3DsoftwareIV目錄摘要.IIABSTRACT.III1緒論.11.1模具行業(yè)的現(xiàn)狀和發(fā)展.11.1.1模具行業(yè)的現(xiàn)狀.11.1.2中國模具技術(shù)的進(jìn)步.11.1.3中國模具工業(yè)的發(fā)展方向.31.2課題的來源與意義.51.2.1課題的來源.51.2.2課題的意義.52沖孔落料復(fù)合模.62.1沖裁件的工藝分析.62.1.1材料.62.1.2生產(chǎn)批量.62.1.3精度等級.62.1.4結(jié)構(gòu)形狀.62.2制訂生產(chǎn)方案.62.3零件的工藝計(jì)算.72.3.1工作零件刃口尺寸的計(jì)算.72.3.2排樣.92.3.3沖裁力.112.3.4卸料力、推件力.122.3.5壓力機(jī)公稱壓力的確定.132.3.6壓力中心的計(jì)算.132.4沖裁模設(shè)計(jì)與制造.132.4.1工作零件.132.4.2定位零件.162.4.3卸料與推料零件.182.4.4模架及零件.203落料、拉深、沖孔復(fù)合模.223.1零件工藝分析.223.2零件工藝方案的確定.233.3分析零件的沖壓工藝性并確定工藝方案.233.4工藝計(jì)算.243.4.1沖裁力、卸料力、推件力、拉深力的計(jì)算及選出壓力機(jī).243.4.2排樣、沖裁模間隙及凹模、凸模刃口尺寸公差計(jì)算.263.4.3首次無凸緣拉深的有關(guān)計(jì)算.29V3.5有關(guān)模具零件結(jié)構(gòu)的計(jì)算.303.5.1沖孔凸模.303.5.2落料凹模.303.5.3拉深凸模（沖孔凹模）.303.5.4拉深凹模（落料凸模）.313.5.5卸料裝置.313.5.6定位零件.323.5.7固定板、墊板.323.5.8模架、導(dǎo)柱、導(dǎo)套.324拉深模.334.1工藝分析.334.2工藝計(jì)算.334.2.1拉深直徑.334.2.2拉深力的計(jì)算.334.2.3圓角半徑.344.2.4拉深模具的間隙.344.2.5拉深高度.344.2.6拉深凹模和凸模的尺寸.344.3有關(guān)模具零件結(jié)構(gòu)的計(jì)算.344.3.1拉深凸模.344.3.2拉深凹模.354.3.3模架及其他.355復(fù)合沖壓模具.375.1沖裁件的工藝分析.375.1.1材料.375.1.2生產(chǎn)批量.375.1.3精度等級.375.1.4結(jié)構(gòu)形狀.375.2制訂生產(chǎn)方案.375.3零件的
