Claims

[Claims for Utility Model Registration] 1. A means for centering and rotatably supporting the end plate, and connecting the end portion of the cylindrical peripheral wall of the end plate between a female roller on the inside and a male roller on the outside in a part of the circumferential direction. In the apparatus for forming a cylindrical end flange by rotating the end plate by rotationally driving one of these rollers and flange-down the end portion of the cylindrical peripheral wall toward the inner circumference, the flange-down an outer peripheral surface portion of the female roller that forms a transition portion between the cylindrical peripheral wall of the end plate that is not processed and the cylindrical end flange is inclined at about 30 degrees with respect to a surface perpendicular to the axis of the roller; The cylindrical shape of the end plate for a pressure vessel, characterized in that the axis of the male roller is inclined with respect to the axis of the female roller so that the lag side of the male roller in the direction of rotation of the end plate is not higher than the leading side in the direction of rotation of the end plate. Peripheral wall end processing equipment. 2. The apparatus for processing an end portion of a cylindrical peripheral wall of a pressure vessel end plate according to claim 1, wherein the angle of inclination is approximately 0.4 degrees.
