南昌航空大学科技学院学士论文1转向臂零件数控加工工艺、加工仿真摘要本文介绍了转向臂零件加工工艺的基本类型及工艺规程,并重点对工艺过程和数控仿真加工过程进行了分析探讨。本文主要利用三维软件来设计仿真加工的全部过程。本文设计的转向臂,在工农业中的应用非常广泛。通过分析其在锤上模锻的变形过程,应用金属塑性变形基本原理,制定了转向臂的成形工艺。在设计过程中,根据转向臂零件的各种参数,分析了其由坯料变为成形锻件的变形过程,制定出了较为合理的工艺流程由转向臂锻件的制坯过程,设计出了较为经济,使用方便,较为合理的加工过程。关键词工艺设计模具设计南昌航空大学科技学院学士论文2SteeringarmspartsCNCprocessingtechnology,machiningsimulationAbstractThistextintroducedthebasictypeandthecraftrulesdistanceofthehotForgingcraft,layingequalstressontoordertomodelprincipleandtransformprocesstocarryonananalyticalstudytothehammermoldForging.Thispapermainlyusingthreedimensionalsoftwaretodesignsimulationprocessingofallprocess.Thistextdesignofchangedirectionarm,veryextensiveintheapplicationintheworkagriculture.PassanalyticalitthemoldForgingtransformsprocessonthehammer,applyingthemetalstotransformbasicprinciple,drawinguptochangedirectionarmoftakeshapeacraft,andcompletetochangedirectionarmoftheForgingmolddesign.Duringtheperiodofdesign,accordingtochangedirectionvariousparameterofthearmspareparts,analyzeitisanticipatebythemetalstochangeintotakeshapetheForgingpiecetotransformprocess,drawupmorereasonablecraftprocessFromchangedirectionthearmForgingpiecesystemprocess,designmoreeconomic,useconvenience,morereasonablemoldingtool.KeywordCraftdesignThemoldingtooldesign目录南昌航空大学科技学院学士论文3摘要.................................................................................................................................1Abstract21绪论............................................................................................................................51.1高速切削............................................................................................................51.2高精度控制........................................................................................................51.3高柔性化............................................................................................................51.4高一体化.............................................................................................................61.5网络化................................................................................................................61.6智能化.................................................................................................................62生产类型的确定.................................................................................................62.1零件的作用........................................................................................................62.2零件的工艺分析................................................................................................62.21以φ16mm孔的中心线加工表面.............................................................72.22以φ9.3mm孔的中心线加工表面...........................................................73选择毛坯、确定毛坯尺寸、设计毛坯图...................................................73.1求最大轮廓尺寸.................................................................................................73.2选取公差等级CT...............................................................................................73.3求铸件尺寸公差.................................................................................................73.4求机械加工余量等级.........................................................................................83.5求RMA(要求的机械加工余量)......................................................................83.6求毛坯基本尺寸.................................................................................................84工艺路线拟定........................................................................................................94.1定位基准的选择.................................................................................................94.2拟定加工方法和加工方案.................................................................................94.21工艺路线....................................................................................................94.22确定工艺过程方案..................................................................................105选择加工设备及刀具、夹具、量具..........................................................115.1选择加工设备与工艺设备................................................................................115.11选择机床,根据不同的工序选择机床...................................................115.12选择夹具..................................................................................................125.13选择刀具,根据不同的工序选择刀具..................................................125.14选择量具..................................................................................................125.2确定工序尺寸..................................................................................................125.21面的加工(所有面).....................................................................................125.22孔的加工.........................................................................................................136确定切削用量及基本时间.............................................................................13南昌航空大学科技学院学士论文46.1工序号02、03、04..........................................................................
