精品论文冲压弯曲件冲压模具设计摘要随着中国工业不断地发展,模具行业也显得越来越重要。本文针对支架弯曲件的冲裁工艺性和弯曲工艺性,分析比较了成形过程的三种不同冲压工艺(单工序、复合工序和连续工序),确定用一幅级进模完成落料、冲孔和一幅单工序模完成弯曲的工序过程。介绍了支架弯曲件冷冲压成形过程,经过对支架的批量生产、零件质量、零件结构以及使用要求的分析、研究,按照不降低使用性能为前提,将其确定为冲压件,用冲压方法完成零件的加工,且简要分析了坯料形状、尺寸,排样、裁板方案,冲压工序性质、数目和顺序的确定,进行了工艺力、压力中心、模具工作部分尺寸及公差的计算,并设计出模具。还具体分析了模具的主要零部件(如冲孔凸模、落料凸模、卸料装置、弯曲凸模、垫板、凸模固定板等)的设计与制造,冲压设备的选用,凸凹模间隙调整和编制一个重要零件的加工工艺过程。列出了模具所需零件的详细清单,并给出了合理的装配图。通过充分利用现代模具制造技术对传统机械零件进行结构改进、优化设计、优化工艺方法能大幅度提高生产效率,这种方法对类似产品具有一定的借鉴作用。关键词:支架,模具设计,级进模,冲孔落料,弯曲精品论文StampingBendingStampingMoldDesignABSTRACTWithChina'sindustrialdevelopingconstantly,moldindustryisbecomingmoreandmoreimportant.Basedonthestentbendingblankingprocessandbendingprocess,Comparativeanalysisoftheprocessofformingthreedifferentstampingprocess(singleprocesses,complexprocessesandcontinuousprocesses)confirmcompletionoftheblanking,punchingandasingleprocedurecompletedthebendingmodulusprocesses.Onthecoverofthecoldbendingstents,rightafterthecoverofthemassproduction,qualitycomponents,andtheuseofstructuralcomponentsoftheanalysis,research,inlinewithlowerperformanceprerequisitetotheidentificationofstampings,Stampingmethodusedtocompletetheprocessingcomponents,andabriefanalysisoftheblankshape,size,layout,theconferenceboard,stampingprocessesinnature,numberandsequencedetermination.Fortheprocess,thecenterofpressure,thediesizeandthetoleranceofthecalculation,designmold.Alsoanalyzesthemoldofthemaincomponents(suchasmould,punchholepunch,unloaderdevice,punch,plate,bendingplateetc)designandmanufacturing,stampingequipmentselection,punch-gapadjustmentandestablishmentofavitalpartsmachiningprocess.Dierequirementssetoutadetailedlistofparts,andgivesareasonableassembly.Byfullyutilizingmodernmanufacturingtechnologytomoldtraditionalmechanicalpartsforstructuralimprovements,designoptimization,processoptimizationmethodscangreatlyenhanceproductionefficiency,themethodofsimilarproductshavesomereference.KEYWORDS:stents,molddesign,progressivedie,punchingblanking,bending精品论文目录前言............................................................................................................1第1章对加工零件的工艺分析..............................................................51.1零件分析.........................................................................................51.1.1冲压件的工艺分析............................................................51.1.2分析比较和确定工艺方案...............................................61.1.3弯曲件的工艺分析............................................................7第2章冲裁模............................................................................................82.1冲压模具的工艺分析与设计计算.............................................82.2工作力的计算.............................................................................102.2.1落料力................................................................................102.2.2冲孔力................................................................................112.2.3卸料力................................................................................112.2.4推料力................................................................................112.2.5冲侧刃缺口的力............................错误!未定义书签。2.2.6总冲压力...........................................................................122.3确定模具压力中心.....................................................................122.4确定凸、凹模刃口尺寸.............................................................152.4.1冲孔部分...........................................................................162.4.2落料部分...........................................................................172.5成型零部件的结构设计............................................................182.5.1冲孔凸模结构设计...........................................................182.5.2冲孔凸模结构设计...........................................................192.5.3凹模结构设计....................................................................192.6模具的整体设计.........................................................................202.6.1选择模具结构形式...........................................................202.6.2操作方式............................................................................202.6.3模架类型............................................................................212.6.4定位方式的选择...............................................................21精品论文2.6.5卸料和出料方式的选择..................................................212.6.6导向方式选择....................................................................212.6.7定位零件设计....................................................................212.6.8导料板设计........................................................................212.6.9卸料板设计........................................................................222.6.10垫板设计..........................................................................232.6.11模柄选择..........................................................................242.6.12凸模固定板的设计.........................................................252.6.13导柱导套选择..................................................................262.6.14模座选择..................
