湖南工學(xué)院2006屆畢業(yè)設(shè)計(jì)說明書題目院(系)、部：機(jī)械工程系學(xué)生姓名：劉寸法指導(dǎo)教師：劉吉兆職稱教授專業(yè)：機(jī)械設(shè)計(jì)班級(jí)：機(jī)設(shè)0301完成時(shí)間：2006年5月摘要隨著中國(guó)工業(yè)不斷地發(fā)展，模具行業(yè)也顯得越來越重要。本論文便是設(shè)計(jì)加工空氣濾清器殼的模具。首先對(duì)加工零件進(jìn)行了加工工藝和結(jié)構(gòu)工藝的分析。通過計(jì)算毛坯尺寸和拉深系數(shù)提出了四種方案，最后確定采用落料、正反拉深復(fù)合模。對(duì)模具的排樣做出了合理的布置，使材料利用率達(dá)到較高的水平。計(jì)算了沖壓過程中所需要的各種沖壓工藝力，包括落料力、卸料力、壓邊力、拉深力、頂料力等，并對(duì)壓力機(jī)進(jìn)行了合理的噸位初選。復(fù)合模在結(jié)構(gòu)上采用了正裝的形式，計(jì)算出了落料、正拉深和反拉深工作部分的尺寸。對(duì)模具的閉合高度進(jìn)行了合理的確定，還設(shè)計(jì)出模具的主要零件落料凹模、凸凹模、反拉深凸模、反拉深凹模、凹模固定板等。列出了模具所需零件的詳細(xì)清單，并給出了合理的裝配圖。由于拉深的深度較大，對(duì)壓力機(jī)的電機(jī)也進(jìn)行了功率校核并提出了潤(rùn)滑的附加工序，能使拉深順利完成。最后對(duì)模具的一個(gè)主要零件導(dǎo)套進(jìn)行了簡(jiǎn)單的加工工藝路線的制定。本設(shè)計(jì)對(duì)于采用單動(dòng)壓力機(jī)進(jìn)行正反拉深具有一定的參考作用。關(guān)鍵詞畢業(yè)論文；模具設(shè)計(jì)；復(fù)合模；正反拉深A(yù)BSTRACTDevelopsunceasinglyalongwiththeChineseindustry,themoldprofessionalsoappearsmoreandmoreimportantly.Thepresentpaperthenisdesignstheprocessingairfiltershellthemold.Firsthascarriedontheprocessingcraftandthestructurecraftanalysistotheprocessingcomponents.Proposedthroughthecomputationsemifinishedmaterialssizeandthedrawingcoefficientfourkindofplans,finallydeterminedusesfallsthematerial,theproandcondrawingsuperposabledie.Hasmadethereasonablearrangementtothemoldplatoontype,enablesthematerialusefactortoachievethehighlevel.Hascalculatedeachrammingcraftstrengthwhichintherammingprocessneeds,includingfallsnearbythematerialstrength,theex-denningstrength,thepressurethestrength,thedrawingstrength,thetopmaterialstrengthandsoon,andhascarriedonthereasonabletonnageprimaryelectiontothepress.Thesuperposablediehasusedthetruethingforminthestructure,calculatedfellthematerial,thedrawingandthecounter-drawingeffectiverangesize.Closedhascarriedonthereasonabledeterminationhighlytothemold,butalsodesignsthemoldthemajorpartstofallthematerialconcavemold,theconvex-concavemold,thecounter-drawingraisedmold,thecounter-drawingconcavemold,theconcavemolddeadplateandsoon.Listedthemoldtoneedthecomponentsthedetaileddetailedlist,andhasproducedthereasonableassemblydrawing.Becausethedrawingdepthisbig,alsocarriedonthepowertothepresselectricalmachinerytoexamineandtoproposethelubricationattachmentworkingprocedure,couldcausethedrawingsmoothlytocomplete.Finallyledthewraptomoldmajorpartstocarryonthesimpleprocessingcraftrouteformulation.Thisdesignregardingusesthesingleactingpresstocarryontheproandcondrawingtohavethecertainreferencefunction.Keywordsgraduationthesis；molddesign；superposabledie；proandcondrawing目錄1分析零件的工藝性12確定工藝方案22.1計(jì)算毛坯尺寸22.2計(jì)算拉深次數(shù)42.2.1正拉深42.2.2反拉深52.3確定工藝方案53主要工藝參數(shù)的計(jì)算63.1確定排樣、裁板方案63.2確定各中間工序尺寸83.3計(jì)算工藝力、初選設(shè)備93.3.1落料、正拉深過程9(1)落料力9(2)卸料力9(3)拉深力10(4)壓邊力103.3.2反拉深過程11(1)反拉深力11(2)頂料力113.3.3拉深功的計(jì)算113.3.4初選壓力機(jī)114模具的結(jié)構(gòu)設(shè)計(jì)134.1模具結(jié)構(gòu)形式的選擇134.2模具工作部分尺寸計(jì)算134.2.1落料134.2.2正拉深154.2.3反拉深165選用模架、確定閉合高度16
