Abstract
PURPOSE: To improve appearance, surely avert the problems of strength decrease and safety and form patterns of the cylindrical part of a barrel body made of metal by bulging the barrel body by the use of a split-die engraved with grooves at the joining part.
CONSTITUTION: A die 2 is mounted onto a press holder 1 by means of a plurality of blots, and cylindrical parts 2a, 2b are formed splittable in the right and left directions with a splitting face 3 as a boundary. In addition, urethane rubber 6 of an inside die is provided to the holder 5 fixed to an elevating ram 4, and a retaining flange 8 is provided integrally to the top end of a top opening cuplike blank material 7 having beforehand been deep drawn from a thin Al blank material. After the respective parts have been set in the above-mentioned manner, the ram 4 is lowered and the rubber 6 is expanded to increase diameter, whereby the blank material 7 is bulged so as to conform to the inside surface 9 of the die 2. Thence, the ram 4 is moved upward, and the die parts 2a, 2b are opened, whereby the cylindrical part of the barrel body made of metal having the pattern consisting of beads 12 or 14 by the grooves 11 formed at the boundaries of the die 2 is obtained.
