Abstract
PURPOSE: To manufacture the good shaped ring body free from the under-fill at high accuracy and at high yield of material, by roll forming entire surface of the ring body using a pair of rolls for radially roll forming and more than three rolls for roll forming in the axial direction.
CONSTITUTION: When the rolling blank for the ring body 23 is carried into the ring body rolling mill, the roll 25, roll 26 and roll 27 are respectively driven to rotate, and also, the roll 24 and the axially rolling roll housing 38 are radially moved toward the roll 25; and then, the radial rolling for the ring body 23 is started by the roll 24 and the roll 25. Since the roll 28 is held at the specified height from the beginning, the rolling for the portion (b) of the ring body 23 is started almost simultaneously with the start of radial rolling by the rolls 24, 25. Besides, when the portion (e) of the ring body 23 contacts with the roll 25, this is detected by the sensing tip 57, and the reduction due to the roll 27 is started by the control signal owing to this detected value; hereafter, the rolling for the portion (a) of the ring body 23 is carried out as far as the specified position; hererby, all portions aWf are roll formed by the rolls 24W28.
