Abstract
PURPOSE: To enable a projecting part of high and stable strength to be obtained in the case of forming the projecting part by pressing a plate body, by forming reinforcing ribs to the coupling part of the plate body and the projecting part by the use of a predetermined punch.
CONSTITUTION: A plate body 11 is interposed between an upper die consisting of a shank 21 applying pressing force, an upper die set 22, a punch holer 23, a punch 24, a stripper spring 25 and a stripper 26 and a lower die consisting of a material guide 27, a die 28, a lower die set 29, an ejecting spring 30 and an ejecting plate 31. Thence, when the punch 24 is pushed to the plate body 11 by exerting a pressing pressure to the upper die, a projecting part 12 is formed by the tip of said punch 24 and the hole 28a of the die 28; at the same time, a plurality of reinforcing ribs 14 corresponding to the recesses 32 formed at the end of the punch 24 are formed in the coupling part 13 of the plate body and projecting part.
