JH36-400机械压力机机身部分及其上横梁加工工艺的设计毕业论文.doc

I摘要通过对机械压力机的发展现状的分析，以及参考双点机械压力机的设计，确定了本课题的主要设计内容。在确定了机械压力机初步设计方案后，决定采用传统理论方法对JH36400机械压力机机身部件进行设计、计算、强度校核和对压力机上横梁加工工艺的设计及其计算，采用AUTOCAD设计软件对传动系统中各主要零部件及总装图进行了工程绘图，在参考了某公司生产的闭式双点机械压力机机身部件以及查阅了大量关于机身部件设计的书籍后，确定机身部件的设计方案，并对其进行了可行性分析，最后对整个设计进行系统分析，得出整个设计切实可行。关键词机械压力机机身部件加工工艺。IIAbstractThroughtothemechanicalpresssdevelopmentpresentsituationsanalysis,aswellasreferstotheJH36400mechanicalpresssdesign,hasdeterminedthistopicmaindesigncontent.Afterhavingdeterminedmechanicalpresspreliminarydesignplan,decidedthatusesthetraditionaltheorymethodtocarryonthedesign,thecomputation,theintensityexaminationtotheJH36400mechanicalpressurefuselagepartessystemUsedtheAUTOCADdesignsoftwareeachmainsparepartandthefinalassemblydrawinghascarriedontheprojectcartographytothefuselagepartessysteminInreferredtosomecompanytohaveproducedtheclosedtwopointmechanicalpressureenginedrivesystemwhichaswellashasconsultedmassivelyafterthetransmissionsystemdesignbooks,thedefinitefuselagepartessystemsdesignproposal,hasdrawnupthetransmissionsystemschematicdiagram,hasgivenfuselagepartessystemsworkinginstructions,andhascarriedonthefeasibilityanalysistoit,finallycarriedonthesystemanalysistotheentiredesign,obtainedtheentiredesigntobepracticalandfeasible.Keywordsmechanicalpressepartesofbodyprocessing徐州工程学院毕业设计论文I目录1概述......................................................................11.1绪论..................................................................11.2曲柄压力机的工作原理与结构组成........................................21.3曲柄压力机的发展概况..................................................41.4通用曲柄压力机的型号和技术参数........................................61.4.1曲柄压力机的型号...................................................61.4.2通用曲柄压力机的技术参数...........................................82机身结构的设计............................................................92.1机身类型..............................................................92.2机身结构设计.........................................................102.2.1机身设计..........................................................103机身强度计算.............................................................123.1立柱和拉紧螺栓计算...................................................123.1.1立柱和拉紧螺栓的受力和变形情况....................................123.1.2立柱强度验算......................................................133.1.3拉紧螺栓的强度验算................................................143.2上横量和底座的计算...................................................183.2.1上横量和底座的受力分析............................................183.2.2上横梁的计算......................................................193.3压力机底座的计算.....................................................234闭式组合机身变形计算.....................................................264.1双点压力机底座变形计算公式...........................................264.1.1底座变形计算公式..................................................264.1.2压力机底座变形计算................................................274.2双点压力机上横梁变形计算.............................................274.2.1上横梁变形计算公式................................................274.2.2上横梁变形计算....................................................285机身的紧固...............................................................295.1紧固的方法分类.......................................................295.2紧固的方法选择.......................................................306上横梁加工工艺设计.......................................................316.1上横梁的作用.........................................................316.2上横梁的工艺分析.....................................................316.2.1技术要求分析......................................................31徐州工程学院毕业设计论文II6.2.2加工方法..........................................................326.3上横梁工艺规程设计...................................................326.3.1零件的生产类型....................................................326.3.2零件各表面加工顺序的确定..........................................336.3.3切削用量的选择....................................................336.3.4数据计算..........................................................34总结...............................................................43致谢...............................................................44参考文献............................................................45附录.................................................错误未定义书签。附录一....................................................错误未定义书签。附录二....................................................错误未定义书签。
