Abstract
The invention discloses a punching device for an oil cylinder pipe. Compared with the traditional punching process that punching is carried out from outside to inside, holes are formed by punching the inner wall of the pipe outwards through hydraulic pressure, and therefore the oil pressure can be adjusted according to the wall thickness of the pipe; a clamping ring structure protects the outer wall of the pipe from the outside, so that collapse of surrounding materials of the holes is little, deformation is small, and punching precision is greatly improved; meanwhile, by arranging a discharging outlet, it can be guaranteed that the outer wall of the pipe is free of burrs, and waste materials also can be conveniently discharged, and automatic production can be achieved. The punching device for the oil cylinder pipe is simple in structure and reasonable in design; the holes are formed by punching the inner wall of the pipe outwards through hydraulic pressure, machining precision is greatly improved, system machining stability is improved, and the service life is prolonged.
