某复杂机械零件制造工艺规划

中北大学2016届毕业论文某复杂机械零件制造工艺规划摘要工艺规程，是指导施工的技术文件。一般包括以下内容：零件加工的工艺路线，各工序的具体加工内容，切削用量、工时定额以及所采用的设备和工艺装备等。工艺规程是指导工人操作和用于生产、工艺管理工作的主要技术文件，又是新产品投产前进行生产准备和技术准备的依据和新建、扩建车间或工厂的原始资料。此外，先进的工艺规程还起着交流和推广先进经验的作用。典型和标准的工艺规程能缩短工厂的生产准备时间。本文共分为五章，介绍了对某汽车发动机侧连接盘制造工艺的规划。第一章从零件的作用、零件的生产纲领等方面对零件进行了分析，并确定了毛坯的类型及技术要求和制造方法。第二章根据对零件的分析，做出了本零件工序的设计，通过对两种工序的比较，最终确定了一种最适合本零件加工的工序，并选择了合适的加工机床和刀具。第三章根据每一工序的加工余量，逆推出毛坯的总余量并确定了毛坯的尺寸和结构，并于第四章确定了工序尺寸。第五章对每一工序的切削用量和基本时间进行了计算。本文附录中列举了两种加工方法的工序卡片。关键词：工艺规程、工艺、零件加工、工序卡片中北大学2016届毕业论文ManufacturingprocessplanningforacomplexmechanicalpartAbstractProcessspecification,isatechnicaldocumentstoguidetheconstruction.Generallyincludethefollowing:partsmachiningprocessroute,thespecificcontentsofeachprocessingstep,cuttingtheamountoffixedworkinghoursandtheuseofequipmentandprocessequipment.Processplanningisguidingtheoperationoftheworkersandforproduction,technologyandmanagementworkofthemaintechnicaldocumentthatisbeforenewproductputintoproductionofproductionpreparationandtechnicalpreparationbasisandnewconstruction,expansionofaworkshoporfactoryoftheoriginaldata.Inaddition,advancedprocessplanningalsoplaysaroleintheexchangeandpromotionofadvancedexperience.Typicalandstandardprocessprocedurescanshortenthepreparationtimeoftheplant.Thispaperisdividedintofivechapters,weintroducedtheplanforanautomobileenginesideconnectingplatemanufacturingprocess.Thefirstchapterfromtheroleofparts,andotherpartsoftheproductionprogramofthepartswereanalyzedandidentifiedthetypeofblankandtechnicalrequirementsandmanufact-uringmethods.Accordingtothesecondpartofthechapteranalyzesmadeinthispartofthedesignprocess,bycomparingthetwoprocesses,andultimatelydeterminethemostsuitableforthepartsmachiningprocessandselecttheappropriatemachinetoolsandcuttingtools.ChapterIIIallowancesinaccordancewitheachstep,thetotalmarginagainsttheintroductionofblankandblankdeterminethesizeandstructure,andtodeterminethestepsizeofthefourthchapter.Thefifthchapterofthebasiccuttingparametersandtimeforeachstepwerecalculated.Keywords:Processplanning,Process,Partsprocessing,Processcards中北大学2016届毕业论文第Ⅰ页共Ⅱ页目录第1章零件分析及毛坯的选择....................................................................................................11.1零件的分析........................................................................................................................11.1.1零件的作用...........................................................................................................11.1.2确定生产纲领.......................................................................................................11.1.3零件的工艺性分析和零件图的审查.................................................................11.2毛坯的选择........................................................................................................................31.2.1确定毛坯的类型和制造方法.............................................................................31.2.2确定毛坯技术要求..............................................................................................3第2章工序设计...........................................................................................................................42.1定位基准的选择...............................................................................................................42.2确定工艺路线..................................................................................................................42.3工艺路线方案的分析与比较.........................................................................................52.4夹具的选择........................................................................................................................62.5加工设备的选择..............................................................................................................62.6刀具的选择........................................................................................................................6第3章毛坯尺寸的确定................................................................................................................73.1毛坯尺寸计算..................................................................................................................73.2毛坯总余量.......................................................................................................................93.3毛坯图.............................................................................................................................10第4章确定工序尺寸..................................................................................................................11第5章确定切削用量及基本时间.............................................................................................135.1工序5切削用量及基本时间的确定..........................................................................135.2工序10切削用量及基本时间的确定........................................................................165.3工序15切削用量及基本时间的确定........................................................................215.4工序20切削用量及基本时间的确定........................................................................24中北大学2016届毕业论文第Ⅱ页共Ⅱ页5.5工序40切削用量及基本时间的确定.................................
