毕业设计题目轻型越野车空气滤清器固定架的冲压工艺与模具设计学院机械工程学院专业机械工程及自动化班级机升1001学生学号指导教师二〇一二年五月二十四日济南大学毕业设计-I-摘要冲压成形是一个涉及领域极其广泛的行业，深入到制造业的每个方面，冲压成形加工主要是通过冲压模具来实现。冲压模具是大批量生产同类产品的工具，是冲压成形的常用工艺装备。本设计首先根据空气滤清器固定架冲压件的结构特点、生产批量、加工精度进行冲压工艺性分析，确定冲压工艺方案。空气滤清器固定架成型工序包括两个大的部分：一部分是板材的冲孔落料，另一部分为材料的弯曲工艺。因此，由冲压工艺性分析所确定的冲压工艺方案是设计四套模具，分别是冲孔、落料复合模、中间弯曲单工序模、外角弯曲单工序模，外角弯曲单工序模。然后对这四套冲压模具进行工艺计算并设计每套模具所用的零部件：凸模、凹模、凹模固定板、卸料板、弯曲模等。按照冲压模具的设计的步骤，对各套冲压模具选用合适的导柱、导套、模柄及模架等标准件。最终完成空气滤清器固定架冲压件的模具设计。关键词：冲压工艺；复合模；弯曲模；空气滤清器固定架济南大学毕业设计-II-ABSTRACTThestampingisaverywiderangeoftheareasofindustry,intoallaspectsofmanufacturing,stampingformingprocessingtoachievethroughthestampingdie.Thestampingdiesarethetoolsofmassproductionofsimilarproductsisthemainprocessofstampingequipment.Thedesignisfirstbasedonthestructuralcharacteristicsoftheairfilterholderstampings,productionvolume,processingprecisionstampingprocessanalysistodeterminetheprogramofstampingprocess.Theairfilterholdermoldingprocesses,includingpunching,blanking,bending,stampingprocessdeterminedbythestampingprocessanalysisprogramistodesignthreesetsofmold,namely,punching,blanking,bendingsingle-processmode,punchingdowncompositematerial,bendingmode,punchingandblanking,bendingthemiddle,bothendsofthecurvedcompositemode.Andthenpunching,blanking,bendingsingle-processmode,punchingandblanking,bendingcompositemold,punchingandblankingthemiddlebend,bothendsofthecurvedcompositemode,threesetsofstampingdieprocesscalculationanddesignofeachmoldparts:punch,die,punchfixedplateandthefixedplateofthedie,stripperplate,bendingmodulusandsoon.Inaccordancewiththestepsofstampingdiedesigndifferentsetsofstampingdies,theappropriatechoiceofguideposts,guidesleeve,diehandleandmoldstandardparts.Thefinalcompletionoftheairfilterholderofstampingmolddesign.Keywords：Stampingprocess；Punchingblankingthecompositemodulus；Bendingmode济南大学毕业设计-III-目录摘要...............................................................IABSTRACT...........................................................II目录.............................................................III1前言.................................................................12冲压件的工艺方案的制定...............................................22.1冲压件的工艺性分析..............................................22.1.1冲压件的工艺性............................................32.1.2冲压件的精度和粗糙度......................................42.1.3冲压件毛坯尺寸的计算......................................42.2冲压件工艺方案的分析与制定......................................52.2.1零件冲压工艺性分析........................................52.2.2冲压工艺方案的制定........................................63冲孔、落料复合模的设计...............................................83.1模具总体结构方案................................................83.1.1模具结构..................................................83.1.2操作与定位方式............................................83.1.3卸料方式..................................................83.1.4模架类型的选择............................................83.2冲压件冲压力的计算..............................................83.3冲压设备的选择................................................103.3.1模具压力中心的确定......................................103.3.2凸、凹模间隙值的确定....................................103.3.3凸、凹模刃口尺寸的确定..................................113.4冲孔、落料复合模主要零部件的结构设计..........................143.4.1落料凹模................................................143.4.2冲孔凸模................................................153.4.3冲孔凹模的设计..........................................163.4.4凸凹模..................................................163.4.5螺钉与圆柱销的设计与选用................................173.4.6卸料板..................................................17济南大学毕业设计-IV-3.4.7挡料装置................................................183.4.8模座....................................................183.4.9模柄....................................................183.4.10推杆...................................................183.4.11导柱、导套.............................................193.4.12冲模闭合高度的确定.....................................193.5冲孔落料复合模装配图...........................................194弯曲模的设计........................................................214.1模具总体结构方案..............................................214.1.1卸料方式.................................................214.1.2模架类型的选择...........................................214.2冲压件弯曲工艺的计算...........................................214.2.1弯曲件展开尺寸的计算.....................................214.2.2弯曲力的计算.............................................234.2.3顶件力和压料力的计算.....................................244.3冲压件弯曲设备的选择...........................................244.4弯曲模模具设计.................................................254.4.1凸模与凹模的圆角半径.....................................254.4.2凹模深度.................................................264.4.3弯曲模凸模和凹模的间隙尺寸...............................264.4.4模具工作零件结构的确定...................................274.5弯曲模模架及零件设计...........................................284.5.1后侧导柱模架的选用.......................................284.5.2定位板...................................................284.5.3模柄............................
