编号无锡太湖学院毕业设计(论文)题目锁芯套冷冲压工艺及级进模设计信机系机械工程及自动化专业学号学生姓名指导教师(职称副教授)(职称)2013年5月25日无锡太湖学院本科毕业设计(论文)诚信承诺书本人郑重声明所呈交的毕业设计(论文)锁芯套冷冲压工艺及级进模设计是本人在导师的指导下独立进行研究所取得的成果,其内容除了在毕业设计(论文)中特别加以标注引用,表示致谢的内容外,本毕业设计(论文)不包含任何其他个人、集体已发表或撰写的成果作品。班级机械95学号0923215作者姓名2013年5月25日II摘要冲压模具的工作原理主要是根据零件的外形及工艺要求选用合适的凸模和凹模将板料分离或成形而得到所需制件。因为模具主要用于工件的大批量生产,而且模具需要保证冲压产品的尺寸精度和产品质量,所以要考虑模具的设计能否满足工件的工艺性,能否加工出合格的零件,以及后来的维修和存放是否合理等。本次设计中不仅要确保设计的模具做出的零件能满足工作要求、模具要有足够的使用寿命,还要考虑到它的实际工作环境和必须完成的设计任务。根据一系列的分析、设计、查表、计算,最终确定模具的模架采用对角型模架,凸模凹模采用分别加工法,这样可以采用线切割等数控设备来一次完成全部的工序加工。卸料方式采用弹性卸料,排样方式采用有废料斜排的方式以及采用级进冲压。关键词落料翻边冲孔级进模IIIAbstractThisisalockcoresleeveplatepunchingflange,blankingProgressivediemoulddesign.Theprincipleofpunchingmouldistochoosethesuitablemouldtoseparatesheetmetaltogetpartsneededaccordingtotheshapeofthepartsandtechnologicalrequirements.Becausethemouldmajortoproducealotofparts,andmouldneedtoensuretheprecisionandqualityofproducts,sothedesignandmanufactureofthemouldneedtoconsiderthemoulddesigncouldmeetwiththetechnologyofthedesign,canworkoutqualifiedparts,andmaintenanceandstoragewhetherreasonable,etc.Thisdesignnotonlyneedtomakesurethatthepartscanmeetthejobrequirements,tomakesureithaveenoughservicelife,toconsideritsactualworkenvironmentanddesigntaskmustbecompleted.Accordingtoaseriesofanalysis,designing,watchchecking,calculation,andfinallydeterminedthatthemodeofthemouldframewithdiagonaltypeformwork,thepunchconcavedieprocessingmethodwasusedrespectively,socanthelinearincisionandothernumericalcontrolequipmenttoacompletealloftheprocess.UnloadingwayusingelasticanddischargingLayoutmeansusesthewasteinclinedrowofstyleandthestampingmeansuseslevelintostamping.KeywordsBlankingFlangingPunchingProgressivedieV目录摘要............................................................................................................................................IIABSTRACT..................................................................................................................................III目录............................................................................................................................................V1绪论.............................................................................................................................................11.1本课题的研究内容和意义...................................................................................................11.2国内外的发展概况...............................................................................................................11.3本课题应达到的要求...........................................................................................................12工艺性分析和工艺方案的确定.................................................................................................32.1零件图...................................................................................................................................32.2零件的工艺性分析...............................................................................................................32.3模具材料的选用...................................................................................................................42.3.1冷冲模材料的选用要求.................................................................................................42.3.2材料的选择原则.............................................................................................................42.4冲裁工艺方案的确定...........................................................................................................42.5排样.......................................................................................................................................52.5.1排样方法.........................................................................................................................52.5.2搭边值与条料宽度及工位的确定.................................................................................63设计计算.....................................................................................................................................93.1翻边力的计算.......................................................................................................................93.1.1预冲孔大小的确定........................................................................................................93.1.2翻边系数........................................................................................................................93.2冲裁力的计算.....................................................................................................................103.3卸料力、推件力、顶出力的计算.....................................................................................113.4冲压力的计算.....................................................................................................................123.5冲模压力中心的确定.........................................................................................................123.6冲压设备的确定.................................................................................................................144结构设计.......................................
