固定套冲压工艺制定及模具设计摘要:冷冲压是塑性成型的基本方法之一，它利用冲模在压床上对金属（或非金属）板料施加压力使其分离或变形从而得到一定形状并满足一定使用要求零件的加工方法，通常在常温下进行所以称冷冲压。冷冲压有生产率高，质量稳定，较高的精度，操作方便，材料利用率高等优点。本篇毕业设计首先针对固定套的几何外形尺寸、使用性能、生产规模、经济性及变形特点等方面分析其冲压工艺，然后对几种可能的工艺方案进行比较，从优选择合理工艺方案并计算排样、冲裁力、选择压力机及标准件规格与各工序模工作部分尺寸及精度；对并落料模、拉深模、冲孔模、翻边模以及切边模的零部件的设计以及装配图进行了详细的说明。关键词：、固定套，落料，拉深，冲孔，翻边，切边，工艺计算，模具设计TheStampProcessesBasketryandMoldDesignforthefixedsetAbstract:Thecoldstampingisoneofplasticformationessentialmethods,whichusingdiesinpresseson(eithernonmetallic)thesheetinflictionpressureseparateordistorttoobtaincertainshapetothemetalandsatisfycertainoperationrequirementscomponentsoftheprocessing.Usuallyunderthenormaltemperaturecarriesonthereforecallscoldstamping.Thecoldstampinghaslotsofmeritwhoseproductionratewasbirthhigh,qualitywasstable,precisionwashigh,operationwasease,materialusefactorhigher.ThisinstructionbookletfirstlycarriesonthestampprocessesbasketryandmolddesignfortheFixedset.Inviewofitsdemisionalgeometry,thestresscharacteristic,thescaleofproduction,andefficientandsoon.Designingthepossibleseveralcraftplancarryonthecomparisontochoosethereasonablecraftplanliberally.Thenwecalculatethecraftparametertochoicepressmachine.Finally,itisadetailiedexplaintationaboutpartsdesignationofdrawingcompositeblankingdieandpunchingdie.Keywords:Fixedsetof,Blanking,punching,flanging,trimming,crafts,themolddesign目录１引言............................................................1２冲压件的工艺分析及工艺方案的确定................................32．1材料分析..................................................32．2零件的冲压工艺性分析........................................42.2.1冲压件的尺寸精度分析..................................42.2.2冲压件的尺寸精度分析..................................42.2.3冲压件的生产批量分析..................................42.2.3冲压件的工艺分析......................................52．3确定工艺方案..............................................52．4模具结构型式的确定........................................62．6绘画毛坯尺寸计算图........................................73落料模工艺计算及模具设计.........................................73．1落料模的工艺计算..........................................73.1.1落料部分尺寸计算......................................73.1.2落料模压力机选择.....................................103.1.3落料模压力中心的选择.................................123．2落料模模具设计...........................................123.2.1模具总体设计.........................................133.2.2工作零件设计.........................................133.2.3定位零件设计.........................................143.2.4结构零件设计.........................................153.2.5落料模闭合高度的校核.................................163.2.6落料模的模具装配图...................................17４拉深模的工艺计算及模具设计.....................................174.1拉深模的工艺计算...........................................174.1.1拉深部分尺寸计算.....................................174.1.2拉深模压力机选择..........................
