滚轮支架冲压模具设计说明书

洛阳理工学院毕业设计（论文）I滚轮支架冲压工艺与模具设计摘要本论文以滚轮支架为例，在分析了该零件的加工难点后，考虑了几种可行的成形方案。在分析之后，选择了落料冲孔复合，弯曲单工序模的工艺方案。该模具主要工序包括：落料、冲孔，最后弯曲，保证了生产效率以及模具制造的简单、低成本。该模具结构简单灵活、可靠，并能保证产品质量，成本低，对此类零件的复合模设计有重要参考价值。通过本论文我掌握了模具设计的基本技能，懂得了怎样分析零件的工艺性和怎样确定工艺方案，并且了解了模具的基本结构，提高了计算能力，绘图能力，熟悉了模具设计的规范和标准，同时对各个相关的课程都进行了全面的复习。而且我独立思考的能力也有了提高。关键词：滚轮支架,成形工艺,落料冲孔复合,弯曲,模具结构洛阳理工学院毕业设计（论文）IIROLLINGWHEELHOLDERPUNCHINGTECHNOLOGICALANDDIEOFDEVISEABSTRACTTakingarollingwheelholderbeltpulleyasanexample,theformingdifficultiesofthepartwereanalyzed,andfivefeasiblestampingwereputforward.Throughcomparison,process4wasselectedbecauseithadlessprocesssteps,morecompoundprocesses,anditalsocouldensuretheprecisionandcoaxialityofthepart.Principalmanufacturingprocesses,including:blanking,punching,drawing,anti-drawing.Thestampingdiestructurewaspresentedaccordingtoprocess4.Thediewasverysimpleinstructureandcouldreduceprocessstepsandimproveefficiency.Practicehasproved:thestructureofdieisflexible,reliableandcanensureproductqualityandlowcost,itcanbeimportantreferencetothedesignofprogressivedieforsuchparts.Throughthispaperwemasterdiedesignofthebasicskillstounderstandthemoldofwhatpartsoftheprocess,howtodetermineProcess,learnthebasicstructureofthemold,improvedcomputingpower,graphicscapabilities,andisfamiliarwiththenormsandstandardsrelatedtocurriculumsubjectsatthesametimehaveacomprehensivereview,theabilityofindependentthinkinghasalsoimproved.KEYWORDS:rollingwheelholder,formingprocess,bending,diestructure,punchingpress洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章设计任务书和产品图...........................................................3第2章零件的冲压工艺性分析.......................................................42.1零件的工艺性分析及工艺方案选择....................................42.2零件展开图绘制及毛坯尺寸的确定....................................42.2.1毛坯尺寸L计算.........................................................4第3章冲压工艺计算.......................................................................63.1排样形式及材料利用率.......................................................63.1.1排样形式的确定.........................................................63.1.2材料利用率的计算.....................................................63.2冲压力的计算.......................................................................73.2.1计算落料力.................................................................73.2.2计算冲孔力.................................................................73.2.3弯曲力计算.................................................................83.2.4计算卸料力.................................................................83.2.5总压力的计算.............................................................83.3弯曲模具推件力的计算.......................................................83.4压力机的选择.......................................................................93.5模具刃口尺寸计算...............................................................93.5.1落料凸、凹模刃口尺寸计算....................................103.5.2冲孔凸、凹模刃口尺寸计算....................................113.5.3弯曲凸、凹模尺寸计算............................................12第4章模具主要零件设计.............................................................144.1落料凹模的设计.................................................................144.2冲孔凸模的设计及校核.....................................................154.2.1冲孔凸模长度确定...................................................154.3凸凹模的设计.....................................................................164.4弯曲凸模结构设计.............................................................17洛阳理工学院毕业设计（论文）IV第5章落料冲孔复合模结构形式的选择和设计..........................185.1落料冲孔复合模总体结构.................................................185.1.1卸料装置...................................................................195.1.2导向装置...................................................................195.2弹性元件的设计.................................................................195.2.1.橡胶的设计..............................................................195.3顶件、卸料、压边装置的设计..........................................205.3.1.顶件装置的设计......................................................205.3.2.卸料装置的设计......................................................205.3.3.压边装置的设计......................................................205.4模具其他工作零件的设计与选择......................................205.4.1模具非标准零件的选择............................................205.4.2模具标准零件的选择...............................................20第6章弯曲模具的结构设计.........................................................226.1弯曲模具总体结构.............................................................226.1.1卸料装置...................................................................226.1.2导向装置...................................................................226.2顶件装置的设计.................................................................236.3模具其他工作零件的设计与选择......................................236.3.1模具非标准零件的选择............................................236.3.2模具标准零件的选择...............................................23第7章模架的选择与固定零件的设计..........................................247.1落料冲孔复合模模架的选
