摘要： PROBLEM TO BE SOLVED: To prevent local wall-thickness loss which is generated in end parts in the axial direction of a pipe in U forming when manufacturing a UOE steel pipe especially having thick wall-thickness.
SOLUTION: Relief parts 2ba the surfaces of which are brought into contact with a steel plate 3 are tapered as going to an end face are formed, in both end parts in the axial direction of the pipe of a lower rocker shoe 2b of a rocker die 2 which comprises a rocker assembly type U press apparatus. The lower rocker shoe 2b is constituted so that the positions in the axial direction of the pipe of the relief parts 2ba are changeable. When forming the steel plate 3 into a U shape, the plate is formed into the U shape by situating the relief parts 2ba formed in both end parts in the axial direction of the pipe of the lower rocker shoe 2b in the end parts in the axial direction of the pipe of the steel plate 3. When manufacturing the UOE steel pipe having the thick wall-thickness, the generation of the local wall-thickness loss in the end parts in the axial direction of the pipe is prevented in U forming. Then, it is unnecessary to manufacture the steel plate of which the thickness is on the thick side and the yield is improved.
