铰链垫片级进模设计

中文摘要金属板料冲压是一种在工业生产中应用广泛的加工方法。随着现代各行各业突飞猛进的发展，金属件的结构复杂，精度高，需求量多，加上对生产的安全性、操作的方便性，加工的经济性等要求也日益提高，采用单工位模具已经无法满足生产的需要，许多制造商均采用多工位级进模进行生产。因此，多工位级进模在国内外模具制造业中应用日趋广泛。多工位级进模是在普通级进模的基础上发展起来的一种模具，是当代所有模具中冲压功能最多、结构最复杂、生产效率和自动化程度最高的一种冲模。在多工位级进模结构设计过程中，首先必须设计级进模的总装结构，然后再在此基础上进行模具其他零部件的设计。本论文分析了铰链垫片的工艺性,介绍了铰链垫片多工位级进模总体结构设计，对工件进行了展开计算，确定了工件加工成型的工艺方案和排样方案,对模具进行了工艺计算，根据计算结果进行了凸模、凹模、垫板、导料板、卸料板、镶块等主要零部件的设计，还根据各标准对模具中用到的其他标准件，如模架、导柱导套等，进行了选择与设计。实践证明：该模具结构合理、可靠,并能保证产品质量,对此类零件的级进模设计有参考价值。关键词：级进模;铰链垫片;排样设计AbstractSheetmetalstampingisawidelyusedmethodinindustrialproduction.Withtherapiddevelopmentofmodernbusinesses，thestructureofthemetalpiecesbecomesmoreandmorecomplex.Themetalpiecesalsoneedtohavehighaccuracy.Atthesametime,thedemandsoftheproductionsecurity,theeaseofoperation,theeconomyofprocessingareincreasing.Single-stagemoldscan’tmeetthetheneedsofproduction.Manymanufacturersusethemulti-positionprogressivedieinproduction.Therefore,Multi-positionProgressiveDiesareusedincreasinglywidespreadinthediemanufacturingathomeandabroad.Multi-positionProgressiveDieisdevelopedbasingonthegeneralprogressivedie.Ithasthemostpressingfunction,themostcomplexstructure,productivityandthehighestdegreeofautomation.Inthedesignofthemulti-positionprogressivedie,wemustdesigntheassemblystructureoftheprogressivedie.Andthen,wedesignothercomponentsofit.Inthispage,Ianalyzedthemanufacturabilityofahingegasketpiece,aswellasdesignoftheoverallstructure.Ialsodidthecalculationoftheworkpiece,determinedtheworkpiece’sformingprocessandthenestingprogramanddidacalculationofthemoldprocess.Afterthat,Idesignedthedieinallaspects.Theapplicationshowsthatthedieisfeasibleandreliableinstructureandcanensurethequalityoftheproducts.Keywords:progressivedie;hingegasketpiece;layoutdesign目录第一章绪论.............................................11.1引言..........................................................................................11.2多工位级进模现状及发展.......................................................21.3主要研究内容............................................................................3第二章模具的工艺计算...................................5第一节设计产品图...........................................................................5第二节零件的工艺分析...................................................................52.2.1产品的展开计算....................................................................52.2.2工艺分析................................................................................72.2.3确定工艺方案和排样设计....................................................7第三节工艺计算.............................................................................102.3.1凸、凹模间隙值得确定......................................................102.3.2凸、凹模刃口尺寸的确定..................................................102.3.2.1确定凸、凹模刃口尺寸的原则.....................................102.3.2.2刃口尺寸计算................................................................112.3.3工艺力的计算......................................................................132.3.3.1冲裁力............................................................................132.3.3.2降低冲裁力的方法........................................................142.3.3.3卸料力、推件力和顶件力............................................152.3.3.4弯曲力的计算................................................................172.3.3.5总的工艺力....................................................................182.3.4冲压设备的选择..................................................................182.3.5模具压力中心的确定..........................................................192.3.6冲模的闭合高度..................................................................22第三章模具设计........................................24第一节铰链垫片级进模总体结构的草图设计..............................24第二节模具主要零部件的结构设计..............................................253.2.1凸模和凹模的结构设计......................................................253.2.1.1凸模和凹模的设计原则................................................263.2.1.2凸模的结构设计............................................................273.2.1.3凹模的结构设计............................................................283.2.2导料系统的设计..................................................................293.2.2.1导料板............................................................................303.2.2.2定位装置的设计............................................................323.2.3限位装置的设计..................................................................343.2.4镶块设计..............................................................................343.2.5顶出装置设计......................................................................353.2.6卸料装置的设计..................................................................353.2.7辅助装置的设计..................................................................393.2.7.1固定板............................................................................393.2.7.2垫板...............................................................................413.2.8送料机构与出件方式...........................................................423.2.9其他标准零件的选用..........................................................423.2.9.1模架.....
