Abstract
PURPOSE: To simplify the working and apparatus of folding, and to reduce the quality deviation of the formed products, by forming the first folding working part in outer die of the upper die and the second folding working part in the inner die.
CONSTITUTION: An upper end of an outer case 6 is allowed to contact with a guide 34 the lowering of an upper die 7 and is guided to the first folding working part 32a of an outer die 32 of the upper die 7, and is bent inside by the cooperative action of the 32a of outer die 32 and the outer circumferential surface of the flange parts 15d, 16d, 17d and 18d of the split die of the lower die. At point of the completing time of the first folding operation, the lowering of the outer die 32 is hindered by the split die, thereafter an elastic body 33 is compressed and elastically deformed, and only an inner die 31 is further lowered. Therefore the inwardly folded parts 6a, 6b are further folded downward by the cooperative action of the second folding working part 31b of the inner die 31 and the flange parts 15d, 16d, 17d and 18d of the split die, to form a desired retaining folded pieces 6a, 6b in the upper circumferential rim of the outer case.
