Claims

[Scope of utility model registration request]

In the roll feed of the press, a driving hydraulic cylinder device connected to a rack that drives the roll and a release hydraulic cylinder device that releases the roll are provided, and a rotating cam is attached to the rotating shaft of the press in correspondence with both cylinder devices. A rod having a cam follower at one end that is driven directly or indirectly by the rotating cam is slidably passed through the end face of the hydraulic cylinder, a small diameter portion is provided near the other end of the rod, and the rod has a cam follower at one end that is driven directly or indirectly by the rotating cam. The center hole of a piston that fits into the hydraulic cylinder is fitted so as to be movable by a slight distance, and the piston is provided with an oil chamber that communicates the oil chambers on both sides of the piston, and the oil chamber is connected to the side surface of the piston and the stepped side surface of the rod. The oil chamber on the rod side of the piston is connected to the oil tank, and the oil chamber on the opposite side is connected to the drive and release chamber. A roll feed drive and release device, characterized in that the roll feed drive and release device is connected to a hydraulic cylinder device for use.
