济南大学泉城学院毕业设计--济南大学泉城学院摘要多工位母线加工机是参照国外先进产品，并结合国内实际为提高工作效率设计的配套设备，主要适用于高低压开关柜、变压器制造行业，用于加工各种规格的铜、铝母线。其折弯单元分两种，立折弯加工单元和平折弯单元。折弯机构主要由立柱、凹模、凸模、行程调节机构及驱动液压系统组成。本次设计是立折弯单元，根据多工位母线加工机的工作特点和加工需求，对折弯机构进行结构分析和设计；对不同厚度的板材，计算并合理设计模具尺寸和安装方式，同时对模具的支架结构进行合理设计。另外根据多工位母线加工机的工作条件，设计液压系统，最终达到较为合理的设计目的。通过本课题完成加工机折弯机构的合理设计，增强对机构、模具、液压等方面知识综合应用的能力，并初步掌握机构设计、模具设计、液压传动等方面的知识和方法，提高机械设计、工程应用的能力。关键词：折弯机构；模具安装；液压ABSTRACTReferedtoforeignadvancedproductsandcombinedwiththeactual,thebusmulti-stationmachinewasdesignedforimprovingworkefficiency.Itmainlysuitableforhighandlowvoltageswitchgear,transformermanufactureindustry,usedformachiningofvariousspecificationofcopper,aluminumbus.TheBendingUnitisdividedintotwocategories,standbendprocessingunitandflatbendbendprocessingunit.Thebendinginstitutionsismainlycompositionbypillar,lowerdie,terracedie,strokeadjustingmechanismandhydraulicsystem.Thisdesignisflatbendingunit,accordingtotheworkingcharacteristicsandprocessingrequirementsoftheBendingUnitofBusmulti-stationmachine,foldedinhalfbendingstructureanalysisanddesigninstitution;fordifferentthicknessoftheplankcalculateandreasonabledesignmodlesizeandinstallation,aswellasdesigntheappropriatestentsstruture.Inaddition,designthehydraulicsystemonthebasisoftheworkingconditionsofthemachine,andfinallyachievereasonabledesignpurpose.Throughthistopiccompleteprocessordesignofbendinginstitions,enhancethecomprehensiveapplicationabilityofmechanism,moids,hydraulicetc,andpreliminarymastertheknowledgeofmechanismdesignmolddesignandhydraulictransmission,improvingabilitiesofmechanicaldesignandengineeringapplication.Keywords：bendinginstitution；mouldinstallation；hydraulic目录摘要………………………………………………………………..…….….…=1\*ROMANIABSTRACT…………………………….……….……………………..…………….=2\*ROMANII1前言……….…………………………………………………………….….……………..11.1课题背景………………………………………………………………………….11.2发展现状与趋势...........................……….......…………….………….………..11.3课题目的意义.........................……….......…………….……………………………..32总体方案………
