DEVICE DOR PROCESSING PIPE ENDS

摘要

A tube swaging machine used, in particular, for swaging the ends of tubes or for forging objects of round sections in which hammers are radially arranged relative to a workpiece. The hammers are fixed to a piston in a hydraulic power cylinder, through a piston rod on which a spring is mounted. The hydraulic power cylinder is connected to a vibration generator through a conduit. The vibration generator rotates relative to the workpiece and is mounted on a central shaft. The latter is held in bearings in a housing, and is driven through transmission by a motor which may be in the form of a hydraulic motor. The vibration generator is provided with nozzles, and a screen is mounted on an auxillary shaft having a rotational speed and direction which are independent of the rotational speed and direction of the central shaft.
