技术领域 FIELD

[0001] 本发明涉及一种带波纹结构的管件,特别是一种应用于汽车行业的EGR(Exhaust Gas Recirculation,废气再循环系统)管件的弯管装置及该EGR管件的加工方法。 [0001] The present invention relates to a corrugated tube A tape structures, particularly applicable to an automotive industry EGR (Exhaust Gas Recirculation, exhaust gas recirculation) pipe elbow apparatus and processing method of the EGR pipe.
