Abstract

PURPOSE: To obtain a mouth ring suitable to a seal of small-sized pressure vessel, by bending the mouth ring end part of cylindrical form outward and fitting in a fixed die, and ironing the outside curvature part by using two movable dies, then pressure-welding the end of curvature part at right angle to the mouth ring main body.
CONSTITUTION: Rough curling process is applied to an end part 15a of a cylindrical mouth ring 12 formed from an Al thin sheet or the like by using a movable die 18, and an edge 15b curved outward is formed in a circular section. The inner face of this mouth ring 12a is fitted in a fixed die 20, and is tightened by the first movable die 21 made of a plate at right angle to the opening center line of the mouth ring 12, and a bowl type the second movable die 22 equipped with a recess part 27 concentric to a fixed die 20 is abutted against an end 16b of the edge 15b. By using the both movable dies 21, 22, the outside curvature part of the edge 15b is ironed and reduced in diameter, and, at the same time, the end 16b of the outside curvature part is extended inward and is pressure-welded to the mouth ring main body roughtly at right angle thereto. After forming the edge 15, threading or the like is formed on the mouth ring 12, and the shape and dimensions of the vessel body side edge part are adjusted.
