冷凝器后罩折彎機(jī)的結(jié)構(gòu)裝置設(shè)計(jì)論文.doc

I摘要在研究國內(nèi)外折彎機(jī)械的發(fā)展?fàn)顩r和我國折彎機(jī)械存在的問題的基礎(chǔ)上，根據(jù)零件作業(yè)的要求，設(shè)計(jì)了一種利用液壓元件驅(qū)動(dòng)單向作業(yè)的折彎機(jī)。該機(jī)型采用曲柄滑塊機(jī)構(gòu)，解決了實(shí)際生產(chǎn)之中薄板材的折彎。并且通過對(duì)機(jī)構(gòu)的運(yùn)動(dòng)分析和計(jì)算，通過機(jī)構(gòu)的轉(zhuǎn)化來實(shí)現(xiàn)使折彎力在加工過程之中始終與零件時(shí)刻保持垂直的一臺(tái)空調(diào)冷凝器后罩生產(chǎn)線上專用的三梁二柱式的非標(biāo)準(zhǔn)設(shè)備。該折彎機(jī)的特點(diǎn)是結(jié)構(gòu)簡單，操作容易，工效高。關(guān)鍵詞：折彎機(jī)液壓非標(biāo)設(shè)備IIAbstractInstudiesthedomesticandforeignkneebendmachinerythedevelopmentconditionandourcountrybendsatthekneesinthequestionfoundationwhichthemachineryexists,accordingtothecomponentsworkrequest,designedonekindtoactuatetheunidirectionalworkusingthehydraulicpressurepartthebookletbender.Thistypeusesthecrankslideorganization,hassolvedduringtheactualproductionthethinplatekneebend.Andthroughtotheorganizationmovementanalysisandthecomputation,realizesthroughtheorganizationtransformationmakesthekneebendstrengththroughouttomaintainonaverticalairconditioningcondenserrearcowlproductionlineintheprocessingprocesswiththecomponentstimethespecial-purposethreeLiangtwocolumntypenon-standardequipment.Thisbookletbendercharacteristicisthestructureissimple,theoperationiseasy,theworkefficiencyishigh.Keyword:FoldsthebenderHydraulicpressureNon-signequipmentIII目錄摘要.IAbstract.II第1章緒論.11.1國內(nèi)外的科技現(xiàn)狀.11.1.1國內(nèi)外的現(xiàn)狀.11.2選題目的和意義.21.3本文主要研究內(nèi)容.3第2章折彎產(chǎn)品的零件圖.4第3章折彎機(jī)設(shè)計(jì)原理和機(jī)構(gòu)方案的分析、比較、確定.63.1折彎機(jī)設(shè)計(jì)原理的分析、比較、確定.63.2折彎機(jī)結(jié)構(gòu)方案的分析、確定.7第4章折彎機(jī)設(shè)計(jì)的計(jì)算和結(jié)構(gòu)說明.94.1折彎力的計(jì)算.94.2壓邊力的計(jì)算.104.2.1壓緊塊的設(shè)計(jì).104.2.2壓邊力的計(jì)算.114.2.3壓緊塊中心位置的確定.124.3機(jī)架的受力分析.134.3.1機(jī)架以及相關(guān)零件參數(shù)的確定.134.3.2機(jī)架的受力分析.154.4油缸的選取.224.4.1壓緊缸的選取.224.4.2折彎缸的選取.234.5液壓系統(tǒng)的設(shè)計(jì).294.5.1負(fù)載分析.294.5.2執(zhí)行元件主要參數(shù)的確定.304.5.3擬定液壓系統(tǒng)原理圖.31第5章典型零件的加工工藝過程.34IV5.1導(dǎo)柱.345.2壓緊塊的工藝安排.36結(jié)論.38致謝.39參考文獻(xiàn).40VCONTENTSAbstract.IIChapter1Introduction.11.1Domesticandinternationalcurrentsituationofscienceandtechnology.11.1.1Domesticandoverseasstatus.11.2Purposeandsignificanceofthetheme.21.3Themainresearchcontents.3Chapter2Bendingofproductpartsdiagram.4Chapter3Bendingmachinedesignprincipleandmechanismanalysis.63.1Bendingmachinedesignprincipleanalysis,comparison,determinethe.63.2Bendingmachinestructureschemeanalysis,determinethe.7Chapter4Bendingmachinedesigncalculationandstructure.94.1Bendingforcecalculation.94.2Blankholderforcecalculation.104.2.1Thepressblockdesign.104.2.2Blankholderforcecalculation.114.2.3Thepressingblockcenterpositiondetermination.124.3Aforceanalysis.134.3.1Housingandrelatedpartsparameters.134.3.2Aforceanalysis.154.4Cylinderselection.224.4.1Theselectionofpressurecylinder.224.4.2Theselectionofpressurecylinder.234.5Thedesignofhydraulicsystem.294.5.1Loadanalysis.294.5.2Executiveelementtodeterminem
