扩径滚压导管制造工艺研究

Technics study of expend-diameter filed-roll pipe

针对目前先进飞机液压系统采用的扩径滚压导管连接问题,对扩径滚压导管提出一种新的制造工艺,论证该工艺的可行性,并研制一种新型的扩径滚压器,对解决先进飞机液压系统高压管路泄漏和疲劳断裂的问题有较大帮助。

Aiming at the joint problem of expend-diameter filed-roll pipes applied to the advanced airplane hydraulic pressure system,puts forward a new technic on producing the expend-diameter filed-roll pipe and demonstrates the feasibility.A new type of the expend-diameter filed-roller is invented.It is good help for saving the problem of the leak and the tire-rupture of the advanced airplane hydraulic pressure system high pressure pipes.
