YX32-300500液壓機機身結(jié)構(gòu)設(shè)計及其液壓系統(tǒng)的設(shè)計畢業(yè)論文.doc

I摘要通過對液壓機的特點及分類的分析，確定了本課題的主要設(shè)計內(nèi)容。在確定了液壓機初步設(shè)計方案后，決定采用傳統(tǒng)理論方法對YX32300/500液壓機機身結(jié)構(gòu)進行設(shè)計、計算、強度校核，采用AutoCAD設(shè)計軟件對上橫梁、底座、拉伸滑塊、壓邊滑塊、拉伸缸、壓邊缸、頂出缸、立柱、機身結(jié)構(gòu)進行了工程繪圖，在參考了某公司生產(chǎn)的四梁四柱雙動薄板拉伸液壓機和液壓系統(tǒng)以及查閱了大量關(guān)于液壓系統(tǒng)設(shè)計的書籍后，確定其液壓系統(tǒng)的設(shè)計方案，給出了液壓系統(tǒng)的工作說明書，并對其進行了可行性分析，最后對整個設(shè)計進行系統(tǒng)分析，得出整個設(shè)計切實可行。關(guān)鍵詞液壓機；拉伸缸；液壓系統(tǒng)IIAbstractThroughtothehydraulicpresscharacteristicandtheclassifiedanalysis,Ihasdeterminedthistopicmaindesigncontent.Afterdeterminedthehydraulicpresspreliminarydesignplan,Idecidedusesthetraditionaltheorymethodtocarryonthedesign,thecomputation,theintensityexaminationtotheYX32-300/500hydraulicpressfuselagestructure,usedAutoCADtodesignthemaintraverse,thefoundation,thestretchslide,thepressuretheslide,stretchesthecylinder,thepressurethecylinder,goesagainstthecylinder,thecolumn,thefuselagestructurehascarriedontheprojectcartography,inhasreferredtofourLiangfourcolumndoubleactionthinsteelplatestretchhydraulicpressandthehydraulicsystemwhichsomecompanyproducedaswellashasconsultedmassivelyafterthehydraulicsystemdesignbooks,thedefinitehydrauliccontrolsystemdesignproposal,hasgiventhehydraulicsystemworkinginstructions,andhascarriedonthefeasibilityanalysistoit,finallyright.Theentiredesigncarriesonthesystemanalysis,obtainstheentiredesigntobepracticalandfeasible.KeywordsHydraulicpressstretchescylinderHydraulicsystem徐州工程學(xué)院畢業(yè)設(shè)計I目錄1緒論.11.1液壓機的工作原理.11.2液壓機的特點及分類.31.3液壓機的基本參數(shù).41.4液壓機的發(fā)展概況.61.4.1液壓機的發(fā)展.61.4.2液壓機研究現(xiàn)狀.71.4.3我國自由鍛液壓機和大型鍛件生產(chǎn)的發(fā)展歷程.71.4.4結(jié)束語.102液壓機本體結(jié)構(gòu)及其設(shè)計計算.112.1性能特點及用途.112.2主要技術(shù)規(guī)格.112.3液壓缸的設(shè)計、計算及校核.122.3.1液壓缸部件.122.3.2液壓缸的設(shè)計、計算及校核.122.3.3柱塞.182.4立柱設(shè)計、計算及校核.192.4.1概述.192.4.2受力分析.202.5橫梁設(shè)計、計算及校核.272.5.1橫梁的結(jié)構(gòu)設(shè)計.272.5.2橫梁的強度與剛度計算.293液壓系統(tǒng)的設(shè)計.343.1液壓系統(tǒng)的設(shè)計.343.1.1明確設(shè)計要求、進行工況分析.343.1.2擬定液壓系統(tǒng)原理圖.343.1.3液壓元件的計算和選擇.353.1.4液壓系統(tǒng)的性能驗算.353.2液壓系統(tǒng)原理圖設(shè)計.363.3
