固定架冲侧孔的模具设计

:20091015:(1972-),,:10014934(2010)04002504崔东风(,110141):通过对制件固定架结构及成形工艺的分析,针对传统加工制件侧孔存在的问题及经济性和批量生产的需求,比较了几种加工方法的优缺点介绍了新模具结构的工作原理,提出了此种结构中凹模悬臂和横向窜动问题的解决措施这种新颖的侧冲方式,实现了用垂直方向冲孔来代替原传统理念的水平对冲侧孔并起同样的作用简化了模具结构,大大提高了生产率:成形工艺;侧冲;悬臂;横向窜动;水平;垂直:TG386:BAbstract:Byanalyzingthestructureandtheformingprocessofthefixator,aimingatsideholeproblemsexistedinthetraditionalprocessandtherequirementsofeconomyandmassproduction,theadvantagesanddisadvantagesofseveralprocessingmethodsarecompared.Theprincipleofanewdieandthestructureofitaredescribed.Thesolutionforthecantileverandhorizontaltraverseproblemsareintroduced.Thisnewsidepunchingmethodwiththeverticalpunchcanachievethesamerequirementasthetraditionalprocesswithhorizontalpunch,whilethediestructureissimplifiedandtheproductionefficiencyisimproved.Keywords:formingprocess;sidepunching;cantilever;horizontaltraverse;horizontal;vertical0,,,1,3,,,,,,,,,3,1252010.No.4,,,,,,2,322,,;663,,2,6,2,,(1,2),,1,,,26DieandMouldTechnologyNo.420101.2.3.4.5.6.729.8.9.102425.11.12.13.14.15.16.17.18.1920.213132.22.23.26.27.28.30.2133.1,10,14,11,3.27,(H7/m6),2:(1),,,3,;(2),,1;4()272010.No.41.2.3.4522.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.324,,,,,,,,,:[1].[M].:,2000.[2].[M].:,1988.28DieandMouldTechnologyNo.42010
