Portable electrohydraulic bending machine - has motorized pump driving bending tool and forms table mounted unit

摘要

The machine is able to shape several sections or pipes to even when they are of relatively large size, as often used in maintenance work. The motorized pump is connected to the actuator of the bender by a high-pressure hose, the bender featuring the forming tool I and a bending plate attached to the back-up bracket 4 for setting with respect to the movable jaw of the bending tool. Actuation of a valve handle ensures the displacement of the tool and a relief valve as well as flow control valve ensure the safety of the hydraulic unit. The displacement of the bending tool I is ensured by a hydraulic cylinder fed by the pump. The entire apparatus stands on four feet and may stand on top of a table and the bending process may be accurately controlled.
