Abstract
PURPOSE:To make a rolling roll reusable only by regrinding a roll forming die part even if a circumferential roll forming die is abraded, by forming the circumferential roll forming die with a circumferential plane of a couple of rolling rolls and a protruding annular shoulder part formed on one side of the circumferential plane. CONSTITUTION:When the circumferential roll forming die 11 is abraded, the circumferential plane 12 and the annular shoulder part 13 of the roll forming die 11 are reground; then, the rolling rolls 1, 1 are shifted by each reground amount transversely (direction Y) and downward (direction X); hereby, the shape of the circumferential roll forming die 11 is restored to an initial shape, so that the necessity of usual build-up welding is eliminated. In this case, the rolling rolls 1, 1 are shifted in the direction X by adjusting the thickness of an adjusting liner 9, and are shifted in the direction Y by adjusting the thickness of a liner, etc., of a screw down device or between the roll chocks 3, 3.
