摘　　要：空调集气管采用冲孔翻边后配管焊接的方式进行生产制造。而集气管冲孔翻边加工后成型孔的缺陷,会直接影响后工序配管垂直度及焊接可靠。文章针对冲孔翻边加工工艺进行研究,通过研究补偿性原理,利用不同的椭圆度,形成不同的翻边高度,达到冲孔翻边高度平齐的效果。实现了翻边平均高度差达0.1 mm,焊点平均脉冲寿命提高近1.3万次的可靠性提升。The air-conditioning gas pipe is produced by the punching and the welding.The defects of the finishing holes after collecting pipe punching,which will directly affect the verticality and welding reliable.The article conducts research on the punching process,by studying the compensatory principle,using different elliptical degrees,forming different flange heights,achieving the effect of the height of the punch flakes.Realized the flyback average height of 0.1mm,and the average pulse life of solder joint increases by nearly 13,000 reliability.

关 键 词：翻边 冲孔 平整度 垂直度 可靠性
