河南机电高等专科学校毕业设计说明书1摘要本论文是以液压锻造操作机平行升降机构为基础,设计一套利用液压传动来实现的的升降控制系统集成块,要实现平升、平降、上下倾斜和钳杆回弹等动作,并完成液压原理图设计和液压元件选用,另外对各元件的工作原理进行介绍。论文重点是完成集成阀块尺寸设计、内部油孔设计以及表面粗糙度的选择。同时对系统中油液的输送过程作了介绍,并对其动作也进行了简单的介绍。液压集成块的集成体现了它通油能力大,流阻损失小,泄露少,系统的振动小,元件维修、更换方便和效率高等优点,结构紧凑、元件密度高、占据面积少、变化灵活方便、容易实现标准化。从而大大改善了液压机多年来存在的漏油,安装维修不便和可靠性差等状况。关键词:平行升降机构上下倾斜机构钳杆回弹机构液压集成块液压阀ABSTRACTThepaperistakethehydrostaticforgingoperationmachineparallelelevatingmechanismasafoundation,designingasetofintegrationblockbythecuingcontrolsystemwhichrealizesusingthehydraulictransmission.Theealizesthemovements,includingevenlyrises,evenlytofall,highandlow,nipplingleversnappingbackandsoon,andcompletesthehydraulicpressureschematicdiagram’sdesignandthehydraulicelement’sselect;Moreover,thepapercarriesontheintroductiontovariousparts'principleofwork.ThekeypointofpaperistoCompletethedesignofsizeofthepile-upvalveblock,thedesignofinternaloilholeaswellasthechoiceofsurfaceroughness.Atthesametime,theprocessoftheoiltransportationwasintroducedinthesystem,andtheactionofwhichalsohavehadabriefintroductionTheintegratedblock'sintegrationreflectsitssmallerloss,lessleakage,vibrationsmall,easymaintenance,highefficiencyadvantages,soastoimprovethehydraulicoilspill,installationandmaintenanceinconvenience,andotherconditions,significantlyimprovingthehydraulicperformance.Theintegrationofhydraulicmanifoldreflectsitsbigoil-capacity,thelossofsmallflowresistance,leakless,thevibrationsystemofsmall,componentmaintenance,replacementofconvenienceandhighefficiencyadvantages,compact,high-densitycomponents,andoccupyslessspaceanditschangeisflexibleandconvenient.it’seasytoimplementstandardization.Thusovertheyearsthehydraulicspillingoilandhavinginconveniencedinstallationandmaintenanceandreliabilityinpoorconditionshavebeengreatlyimproved.KeyWords:parallelbodymovementstiltinstitutionsfromtoptobottomclamp-reboundagencieshydraulicmanifoldhydraulicvalve目录摘要..………………………………………………………………………………………..….I绪论..……………………………………………………………….….………………………1
