Abstract

PURPOSE: To produce nozzles having wall thickness and form in a wide range from a sound material, by pressing a punch into the master hole in the pressure vessel main body member from inside, and compressing by filling the gap formed by the nozzle die hole and punch with part of said member.
CONSTITUTION: A nozzle die hole 6 having the diameter and depth nearly equal to the outside diameter and height of a nozzle 5, and a nozzle die 9 having a punch guide hole 8 to guide the nozzle 5 into the bottom part 6' of the die hole 6 are prepared. This die 9 and a punch 7 fitted to a push rod 10 are concentrically set in a press unit, and set into a master hole 11 provided in a pressure vessel main body member 12 by coinciding the centers respectively. Then, the punch 7 is pushed down, and the master hole 11 is expanded toward the side wall of the punch 7, then a nozzle 5 is formed by filling the die hole 6 with part 13 of the member 12. In this case, the material 12 is compressed by the die hole 6, bottom part 6' and punch 7, so as to fill up the die hole 6 completely. The volume of the part 13 must be slightly larger than the volume of the nozzle 5.
