I三角形水阀垫片倒装复合模设计与加工摘要本文设计的是冲孔、落料、复合模,模具结构比较简单实用,使用方便可靠。因为模具生产大批量的生产,而且模具可以保证冲压产品的尺寸精度和产品质量,模具的设计与加工主要考虑到模具的设计能否满足工作的工艺性设计,能否加工出合格的零件,以及后来的维修和存放是否合理等。在本次设计中除垫片孔的精度外更重要的是外圆圆角尺寸精度,不仅要考虑做出的零件能满足工作要求,还要保证它的使用寿命,最后加工出三角形水阀垫片冲压模具模型产品一套。关键词:倒装复合模;冲压;设计;加工IIValvegasketStampingdieDesignandProcessingAbstractAuthor:SheJiWuZuTutor:YuanYongFuThisarticleisdesignedpunching,blanking,ProgressiveDie,Diepracticalexamplesofrelativelysimplestructure,easytouseandreliable.Stampingdiemainlyofsheetmetalforminghavebeenseparatedorpartsoftheprocessingmethods.Becausetheproductionoflargequantitiesofmoldmanufacturing,moldandstampingproductstoensuredimensionalaccuracyandqualityofproducts,DieDesignandManufactureofthemainmolddesign,takingintoaccounttheworkoftheprocesscanmeettherequirementsofdesign,canbeprocessedintoqualifiedparts,aswellassubsequentmaintenanceandstorage,suchasisreasonable.Inthedesignofthegasketholeaccuracyismoreimportantoutsidetheouterfilletsizeprecision,notonlyhavetoconsidersothatthepartsmadetomeetthejobrequirements,butalsotoensurehislife.thecardorderprocess,non-standardpartsoftheprocessofcardprocessingtechnology.Keywords:ProgressiveDie;Stamping;Design;ProcessingIII目录1绪论………………………………………………………………..…..………….…11.1课题背景………………………………………………………………..…………………11.2课题相关工作………………………………………………………..…………11.3本文主要研究内容………………………………………………………………………12冲裁模设计与制造简介……………………………………………………………….……23零件工艺性分析……………………………………..……………………….…………….…23.1工艺分析………………………………………………………….…………….23.2冲裁工艺方案的确定……………………………………………………….…….…….44模具总体结构设计方案……………………………………………………………….……54.1模具类型的选择…………………………………………………………..……54.2操作与定位方式……………………………………………..…………………54.3卸料和出料方式……………………………………………..…………………54.4导向方式的选择…………………………………………………………………………55模具设计工艺计算……………………………………………………………………..……55.1排样、计算条料宽度及步距的确定…………………………………………..55.1.1排样设计与计算………………………………………………………….55.1.2搭边值的确定…………………………………………………………….65.1.3送料步距与条料宽度计算……………………………………………….75.1.4计算材料利用率…………………………………………………..……….…….96冲压力的计算…………………………………………………………………….......……..116.1计算冲裁力的公式………………………………………………………….…116.1.1冲孔力F冲计算…………………………………………………….……126.1.2落料力F落计算…………………………………………………….……126.1.3卸料力和推件力的计算………………………………………….……..126.1.4总压力的计算…………………………………………………………...136.2压力中心的确定和初选压力机…………………………………………...….136.2.1确定压力中心……………………………………………………….…..136.2.2初选压力机……………………………………………………………………….14IV7冲裁间隙的确定………………………………………………………………………….….168凸模和凹模刃口尺寸计算……………………………………………………………..….178.1冲裁模刃口尺寸计算基本原则……………………………………..………..178.2冲裁模刃口尺寸的方法………………………………………………….…...188.3落料凹模、凸模刃口尺寸磨损分析方法………………………………………....209模具主要工作零件部件设计………………………………………...……………….….239.1凹模的设计………………………………………………………………..…..239.1.1冲孔凸模的设计…………………………………………………..…….259.1.2校核冲孔凸模的强度…………………………………………..……….269.1.3凸模与卸料板间隙选取…………………………………………...……279.1.4凸凹模高度的确定………………………………………………...……279.1.5冲裁刃口高度…………………………………………………………...289.1.6凸凹模内外刃口间隙壁厚校核………………………………...………289.2卸料装置的确定………………………………………………………...…….289.2.1卸料零件……………………………………………………………..….289.2.2卸料板的设计………………………………………………………..….289.2.3卸料螺钉的选用…………………………………………………..…….289.2.4弹性元件的选用和计算…………………………………………...……289.3推件装置设计…………………………………………………………………309.3.1定位方式的选择………………………………………………………...309.4模架及导柱导套的设计…………………………………………………...….329.4.1上下模坐的确定………………………………………………….……..329.4.2导柱与导套的设计……………………………………………………...339.4.3模柄及尺寸的计算……………………………………………………...349.4.4确定模具闭合高度……………………………………………………...349.5工作零件结构材料的选用……………………………………………………349.6其它螺钉长度选用标准………………............................................................359.7圆柱销尺寸选用标准…………………………………………………………359.8其它模具零件结构确定…………………………………………………..…..35V9.9冲压设备的选用………………………………………………………………..………3510模具三位建模…………………………………………………………………………...….3610.1三维装配模型……………………………………………………….……….3610.2三维爆炸图………………………………………………..…………………3710.3装配图……………………………………………………………………………….….3711主要模具零件加工工艺过程的确定.....................................................................错误!未定义书签。11.1工作零件加工工艺过程.................................................................................3811.1.1落料凹模加工工艺过程..........................................................................3911.1.2冲孔凸模加工工艺过程..........................................................................3911.1.3凸凹模加工工艺过程..............................................................................3911.2其它模具零件的加工.................................................................................4011.2.1凸模固定板加工工艺过程......................................................................4011.2.2卸料板加工工艺过程..............................................................................4011.2.3上垫板加工工艺过程..............................................................................4111.2.4上模座加工工艺过程..............................................................................4111.2.5下模座加工工艺过程..............................................................................4111.2.6推件块加工工艺过程..............................................................................4111.2模具的装配.....................................................................................................41结论……………………………………………………………………………..…..43致谢………………………………………………………………………………....44参考文献…………………………………………………………………………....45附录…………………………………………………………………………………
