汽车制造四大工艺论文

西南林业大学本科毕业（设计）论文（2012届）题目汽车制造四大工艺的研究教学院系机械与交通学院专业车辆工程学生姓名贺勤政指导教师孟利清（教授）评阅人2012年06月03日汽车制造四大工艺的研究贺勤政（西南林业大学车辆工程专业2008级，云南昆明，650224）摘要：汽车被称为“改变世界的机器”。由于汽车工业具有很强的产业关联度，因而被视为一个国家经济发展水平的重要标志。本论文所研究的内容主要是汽车的四大工艺，冲压工艺作为四大工艺的重中之重，它影响着剩下的三大工艺，所以是本论文的重点。焊接、涂装、总装三大工艺也是论文的重要组成部分，还有对工艺的概述作为研究汽车四大工艺的基础，因此在论文中被放到了首位。汽车制造工艺、装备和设施是实现汽车产品设计目标和生产加工的基本方法和手段，也是实现技术创新的基础。在汽车制造行业中，冲压、焊接、涂装、总装合为四大核心技术（即四大工艺）。关键词：冲压；焊接；涂装；总装；工艺ThefourmanufactureprocessofautomobileHeqinzheng(VehicleEngineering2008,SouthwestForestryUniversity,Kunming,Yunnan,650224)Abstract：Theautomotivewasreferredtoasthemachinethatchangedtheworld.Theautomotiveindustryhasastrongdegreeofindustriallinkage,whichisregardedasanimportantsymbolofacountry'seconomicdevelopmentlevel.Mainlystudiedinthisthesisthefourprocessofautomobilestampingprocessasthefourmostimportantprocess,itaffectstherestofthethreeprocesses,itisthefocusofthispaper.Welding,painting,assemblyofthethreeprocessesisalsoanimportantpartofthepaper,aswellasanoverviewoftheprocessasthebasisforthefourprocessofautomobile,inthepaperwasplacedinthefirstplace.Thecarmanufacturingprocess,equipmentandfacilitiestoachievethedesigngoalsoftheautomotiveproductsandproductionandprocessingmethodsandmeansofachievingthebasisoftechnicalinnovation.Intheautomobilemanufacturingindustry,stamping,welding,painting,assemblytogetherfourcoretechnologies(ie,fourprocesses).Keywords:stampingWeldingCoatingAssemblyprocess目录第一章绪论.........................................................................................................................11.1课题背景和研究意义.............................................................................................11.2国内外汽车制造工艺现状.....................................................................................11.2.1国外汽车制造工艺概述...............................................................................11.2.2国内汽车制造工艺概述...............................................................................21.3课题研究的主要内容和框架.................................................................................2第二章汽车制造四大工艺概述.........................................................................................42.1汽车的生产过程及其特点.....................................................................................42.2工艺基础.................................................................................................................52.3汽车制造的四大工艺组成及其过程.....................................................................5第三章汽车车身冲压、焊接工艺.....................................................................................73.1冲压技术在汽车制造业中的地位.........................................................................73.2冲压工艺的特点及冲压工序的分类.....................................................................73.2.1冲压工艺的概念及特点...............................................................................83.2.2冲压工序的四个基本工序...........................................................................93.3冲压车间设备与材料...........................................................................................113.3.1冲压车间设备.............................................................................................113.3.2冲压车间材料.............................................................................................143.4焊接的概念及其方式和焊装工艺.......................................................................153.4.1焊接的定义.................................................................................................163.4.2焊接的常用方式.........................................................................................163.5汽车车身冲压和焊接应注意的问题...................................................................20第四章汽车车身涂装、总装工艺...................................................................................234.1涂装前处理工艺...................................................................................................234.2涂装工艺...............................................................................................................254.2.1阴极电泳涂装.............................................................................................254.2.2中涂和面涂喷涂工艺.................................................................................274.2.3涂膜的固化（干燥）工艺.........................................................................304.3汽车装配概念及其特点.......................................................................................304.4装配生产组织形式...............................................................................................314.4.1固定式装配.................................................................................................314.4.2流水式装配.................................................................................................324.5汽车车身涂装和总装工艺应注意的几个问题...................................................33第五章结论.......................................................................................................................365.1总结.......................................................................................................................365.2展望..........
