Abstract

PURPOSE: To perform a fine press forming of a pressure vessel head in high yield and to reduce the time of machining, by forming a blank in a polygonal-shape and forming the titled head by using a punch and a flat die.
CONSTITUTION: A polygonal-shaped blank 5, made of a sheet material, is formed by using a lower flat die 2 and a upper punch 1. The blistering of the blank 5 near its center part is prevented and the thickness deviation of it is reduced owing to the larger hydrostatic effect generated near the mouth of the die 2 during the press forming. Accordingly, said work needs no reforming work, so that the yield is improved and the production cost of the lower die is reduced.
