机械毕业设计568电动液压滚槽机设计

本科毕业论文（设计）题目：电动液压滚槽机设计学院：工学院姓名：学号：20101144专业：机械设计制造及其自动化年级：10级指导教师：二0一四年五月摘要滚槽机是一种新型实用的，用于加工管子连接端沟槽的机械设备。电动液压滚槽机毕业设计2以往，管路的连接一般采用焊接、螺纹、法兰等方法，这类方法一般容易有污染物或者焊渣污染，或者需要二次镀锌，而且还受到安装场所的限制，导致安装速度慢、费用高等缺陷，所以现在也有采用沟槽式机械接头来连接管路，来克服上述连接方式所存在的弊端，但随之而来的是管子连接端沟槽的加工问题。如果采用车床加工的话，不仅速度慢、难度大，而且花费也大。目前，似乎还没有特别行之有效的办法。本设计的目的是在于，提供一种以沟槽式机械连接接头来加工的管路，采用管子连接端沟槽,效果较好的专用设备。滚槽机的工作原理就是根据液压传递原理，利用两个滚动轮对其中间的管壁不断的挤压而形成沟槽；特点是采用液压加压吨位大，适应性强，凸凹模更换方便迅速，生产效率高；广泛用于建筑工地的管道安装，完成用于管路连接的各种管子的压槽之用。关键字：滚槽机；液压；管子AbstractRollerslotmachineisanewpracticalrollinggrooveofmachineryand电动液压滚槽机毕业设计3equipment,inparticularfortheprocessingofthetubesconnectingtheendofthetrenchrollerslotmachines.Inthepast,thegeneraluseofweldedpipeconnections,threads,flangesandothermethods,suchmethodsaregenerallypronetocontaminationorpollutionofweldingslag,ortheneedforsecondaryzinc,butalsorestrictedtheinstallationsite,resultinginslowinstallation,Highercostsdefect,sonowthereisalsogroovedmechanicalpipefittingstoconnecttoovercometheabovedrawbacksconnection,buttheattendantwasprocessingproblemsconnectingpipeendofthetrench.Ifalathe,thennotonlyslow,difficult,andittakestoobig.Currently,itseemsthatnoparticulareffectiveway.Thepurposeofthisdesignistoprovideamechanicalconnectiontothegroovedpipejointstoprocessusingthepipeconnectionterminalgroove,goodeffectofspecialequipment.Rollslotmachineworksisbasedontheprincipleofahydraulictransmission,usingtworollingwheelsconstantlysqueezedinthemiddleofitswalltoformatrench;characterizedbytheuseoflarge-tonnagehydraulicpressure,adaptable,easytoreplacepunchanddiequicklyhighproductionefficiency;widelyusedinconstructionsitespipelineinstallation,completewithavarietyoftubesforpressurepipelineconnectingthetank.Keywords:Rollerslotmachine；Hydraulicpressure；Tube目录摘要...............................................................1Abstract...........................................................2目录................................................................4电动液压滚槽机毕业设计4第1章绪论.................................................................................................................................41.1滚槽机概述:..............................................................................................................41.2滚槽机的发展历史结构特点.................................................................................51.3滚槽机的工作原理...................................................................................................5第2章课题设计的目的与前景及内容...............................................................................72.1课题的目的与意义......................................................................................................72.2课题发展现状和前景..................................................................................................72.3课题主要内容和要求..................................................................................................7第3章滚槽机机械部分设计..................................................................................................93.1工件工艺分析..............................................................................................................93.2电机的选取.................................................................................................................103.3减速器的选取............................................................................................................103.4联轴器的计算与选取..............................................................................................123.5轴承的选取.................................................................................................................133.6轴的初步计算与设计及校核.................................................................................143.7花键的设计与校核...................................................................................................173.8凹模与凸模的设计...................................................................................................183.9支撑架的设计............................................................................................................19第4章液压部分设计...........................................................................................................214.1滚槽机液压系统的概述........................................................................................214.1.1滚槽机液压系统的组成...........................................................................214.1.2滚槽机的液压执行元件...........................................................................214.2滚槽机液压系统的设计........................................................................................224.2.1液压缸的设计与计算................................................................................224.2.2液压泵的选取.............................................................................................264.2.3辅助元件的确定............................................................................................274.3液压系统漏油和噪声控制...................................................................................284.3.1液压系统漏油控制....................................................................................28
