洛阳理工学院毕业设计（论文）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I洛阳理工学院毕业设计（论文）ROLLINGWHEELHOLDERPUNCHINGTECHNOLOGICALANDDIEOFDEVISEABSTRACTTakingarollingwheelholderbeltpulleyasanexample,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,punchingpressII洛阳理工学院毕业设计（论文）III洛阳理工学院毕业设计（论文）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......................................
