数控线切割机床本体设计VIP免费

摘要电火花线切割加工（wire-EDM）是一种基于电火花加工技术的适应性流程加工技术，它可以被用在具有二维到三维复杂形状的而且是导电的原材料的加工上。电火花线切割加工最常见的应用是在压模、挤压模、粉末冶金的铸模和标准摸板的装配工中。这样就可以加工出以往依靠花费很高的磨床或昂贵的传统意义上的电火花的电极来进行加工的工件。电火花线切割加工技术是机电一体化技术，是机械、电工、电子、数控、自动控制、计算机应用等多门学科、专业知识的综合运用。此次设计包括机床的总体布局设计，横向进给、纵向进给设计，其中还包括齿轮的强度计算，滚珠丝杆较核，轴承寿命的验算。这次设计的基本方法包括现场实习，查阅资料，请教专业人士及老师的帮助。关键字：电火花线切割加工；横向进给；纵向进给AbstractWireelectrical-dischargemachining(wire-EDM)isanadaptationofthebasicEDMprocess,whichcanbeuseforcuttingcomplextwo-and-three-dimensionalshapesthroughelectricallyconductingmaterials.Wire-EDMismostcommonlyusedforthefabricationofpressstampingdies,extrusiondies,powdercompositiondies,profilegages,andtemplates.Complicatedcutoutscanbemadeindifficult-to-machinemetalswithouttheneedforhigh-costgrindingorexpensiveshapedEDMelectrodes,Becausethetechnologyofwireelectrical-dischargemachiningisthetechnologyofmechatronics,anditistheintegrateapplicationofmanysubjectsandprofessionalknowledge,forexamplemechanism,electrician,electron,numericalcontrol,autocontrolandcomputerapplication.Thedesigncontainscollectivitydistributiondesign,landscapeorientationfeeddesign,portraitfeeddesign,circumgyrateworktabledesign.Itstillincludesintensioncalculationofgearwheel,thecheckingofballbearingpoleandthecalculationofaxisgearinglife-span,Thebsasicdesignmethodcontainthatfieldpractice,dataaccess,consultprofessionalpersonageandthehelpofteacher.Keywords:wireelectrical-dischargemachining；Traverse；Longitudinalintoto目录摘要.............................................................................................................................I第1章绪论...............................................................................................................11.1数控线切割机床的研究意义.................................................................11.2数控线切割机床的发展现状.................................................................1第2章总体方案设计.............................................................................................32.1总体方案的拟定........................................................................................32.2主要技术参数的确定...............................................................................4第3章储丝走丝部件结构设计..........................................................................63.1储丝走丝部件运动设计..........................................................................63.1.1对高速走丝机构的要求............................................................63.1.2高速走丝机构的结构及特点...................................................63.2储丝走丝部件主要零件强度计算........................................................133.2.1齿轮传动比的确定......................................................................133.2.2齿轮齿数的确定..........................................................................143.2.3传动件的估算...............................................................................153.2.4齿轮模数估算......................................................................
