The upper die 3 is composed of a pressing die 4 and a pressing punch 5, and the pressing punch 5 is attached to the lower surface of an upper base plate 6 of a press machine (not shown) via a substrate portion 5a of the pressing punch 5. At the same time, the pressing die 4 is suspended from the base plate portion 5a of the pressing punch 5 via a spring 7 provided in a hole formed in the back surface.

The lower die 1 is formed such that the upper surface thereof has a shape along the waveform of the deck plate D shown in FIG. 7, and the tip portion 9 of the die 8 supporting the mountain portion D1 of the deck plate D of the lower die 1 is The deck plate D formed on the lower central inclined surface 10 and the lower ear inclined surfaces 11 and 11 on both sides of the lower central inclined surface 10 which are gentler than the lower central inclined surface 10 and having a predetermined length at the tip of these inclined surfaces 10 and 11. A surface 13 that is flush with the surface of the die 12 that supports the valley portion D2 is formed. Reference numeral 8a in the drawing denotes a V-shaped groove formed on the upper surface of the mold 8 for accommodating the V-shaped reinforcing groove D4 formed in the mountain portion D1 of the deck plate D. Further, 1a is a protrusion that receives the reinforcing protrusion D5 formed in the valley D2 of the deck plate D, and its tip is an inclined surface like the mold 8.

The lower surface of the pressing die 4 has a shape along the waveform of the deck plate D in the same manner as the upper surface of the lower die 1 so that the deck plate D shown in FIG. Through-holes 15 are formed in the tip portion 14 at positions facing the lower central inclined surface 10, the lower ear inclined surface 11 and the surface 13 of the lower mold 1. Further, a hole 16 is provided on the back surface for providing the blade 7, and the pressing punch 5 is mounted in the through hole 15 on the base plate portion 5a of the pressing punch 5 through the spring 7 provided in the hole 16. It is suspended so that it can be inserted and moved up and down relative to the pressing punch 5. In the figure, 4a is a groove for accommodating the reinforcing protrusion D5 formed in the valley D2 of the deck plate D, and the reinforcing protrusion D5 of the valley D2 is provided at the tip of the groove. A through hole 15a through which a pressing punch 5b for crushing is inserted is formed.
