I基于气孔的法兰盘铸件铸造工艺设计摘要法兰盘通常是盘状的金属零件，它主要用于机械工程的连接环节。伴随着我国法兰盘行业的迅速发展，法兰盘的应用范围越来越广，而法兰盘作为一种连接零件，人们对它的精确度要求很高，对于材质的选取也很讲究，本文以一典型结构法兰盘为例，首先进行零件分析，了解要制造的零件的基本情况，然后根据零件的加工要求选择毛坯的材质，再计算加工余量，进而确定毛坯的尺寸，然后根据各加工面的需求，选择加工方法，制定工艺路线，根据零件形状以及精度要求选择适用的机床以及刀具，再计算出各切削用量，避免气孔,完成该法兰盘的数控加工编程，最后根据整体需求完成夹具的选择，最终完成了一个比较基本的法兰盘加工工艺设计。关键词：法兰盘；加工余量；工艺路线；数控编程IIABSTRACTTheflangeisusuallydisc-shapedmetalparts,itismainlyusedforconnectinglinksinmechanicalengineering.WiththerapiddevelopmentofChina'sindustryofflange,flangeisappliedmoreandmorewidely,andasaflangeconnectingparts,theaccuracyisveryhigh,isalsoveryimportanttoselectmaterialininthispaper,atypicalstructureofflangeasanexample,thefirstpartanalysis,understandthebasicsituationofmanufacturedparts,thenaccordingtothemachiningrequirementsofthechoiceofblankmaterial,thencalculatethemachiningallowance,andthendeterminethesizeoftheblank,andthenaccordingtothemanufacturingofthedemand,choiceofprocessingmethods,thedevelopmentofprocessroutes,accordingtopartTheshapeandaccuracyformachinetoolandcuttingtool,thencalculatetheamountofcutting,NCmachiningprogrammingoftheflange,accordingtotheoveralldemandforcompletefixtureselection,thefinalcompletionoftheprocessofamorebasicflangedesign.Keywords:Flange;Machiningallowance;Processline;NCprogramming目录绪论......................................................................................................................................11.零件的分析.........................................................................................................................21.1法兰盘的作用...........................................................................................................21.2法兰盘的种类...........................................................................................................21.3法兰盘的零件图.....................................................................................................32.毛坯的选择.........................................................................................................................42.1毛坯的材料选择.......................................................................................................42.2毛坯尺寸的选取.......................................................................................................42.3加工余量的计算.......................................................................................................53.工艺规程的设计.................................................................................................................63.1工艺路线的拟定.......................................................................................................63.2机床和刀具的选择...................................................................................................73.3切削用量的确定.......................................................................................................93.4数控加工编程..........................................................................................................
