ABSTRACT:
The present invention relates to mills for cold rolling of tubes, and more particularly to the improvement of a feeding device incorporated in a tube cold-rolling mill. The feeding device in question comprises a means for pushing the tube to be rolled, a driven continuously moving link arrangement connected with the tube pushing device through a device for transmitting continuous motion of said link arrangement into intermittent motion of the pusher means along the axis of rolling. The transmission device comprises a body, a sleeve slidable in the travelling direction of the pusher device by means of the link arrangement, and two coaxially arranged resilient members with different degrees of rigidity, one of said resilient members being preloaded.
The resilient members each having its one end connected to the sleeve, and the other end to the pusher means, the other resilient member being connected to the body. The feeding device is thus rendered simple in construction, substantially smaller in weight, thereby contributing greatly to higher production efficiency of the tube cold-rolling mill.
