Claims

[Scope of utility model registration request]

It comprises a means for rotating a workpiece, and a roll processing means for joining the workpiece from the opposite side of the rotation means, and the roll processing means plastically forms a gradually opening tapered hole at the center of an end surface of the workpiece. The roll processing device is configured to process a workpiece, and the roll processing means includes a workpiece centering tool that presses the outer peripheral edge of an end face of the workpiece in a centripetal direction, and a workpiece centering tool that holds the tool and rotates the workpiece. A roll holder fixedly arranged coaxially with the workpiece, a sleeve coaxially and rotatably housed within the roll holder, and a tapered tip of the sleeve rotatably housed at an eccentric position within the sleeve. Roll processing characterized by having a processing roll whose surface can move in and out for a certain length from the tip of the sleeve toward the tapered hole of the workpiece, and a pressurizing means that constantly applies a pressing force in the direction of the tip to this roll. Device.
