The device comprises a cylinder 40, a piston 35, a piston rod 36a to which the piston is attached, a punch 18 driven with the piston, an extension tube 25 connected to the cylinder, a frame 53a through which the extension tube passes, an upper tube bracket 47 and a lower tube bracket 200 and an anvil 54 mounted on the frame. A stopper 206 restricts the maximum extended position of the punch to a predetermined position, and a spacer 57 into which the extension tube is inserted positions the extension tube 25 such that at the maximum extended position of the punch the rivet is driven and set satisfactorily. <IMAGE> |
