Abstract
PURPOSE: To reduce the cost, by bending a long steel plate by a vertical bender, guiding it by a guide roller, shifting it, and easily bending it, holding its high roundness.
CONSTITUTION: A long steel plate 1 is brought to bend-working by making it pass through between an inside roller 2A and an outside roller 2B of a vertical roller bender 2, and the lower part of a curved steel plate 3 which is fed out is supported by a supporting roller 18 which is fed out in order on a circular guide rail 4. Also, the inside and outside surfaces of the curved steel plate 3 are supported by an inside guide roller 5A and an outside guide roller 5B, and the curved steel plate 3 is moved along the circular guide rail 4, preventing its inclination and twist. In this way, a circular curved steel plate having length which is equal to circumferential length of 1 ring is formed, and 1 steel plate ring is manufactured by butt-welding both the end parts. A cylindrical structure made of a steel plate is manufactured by laminating said steel plate ring.
