字状に喰い込んでゆく。 With the above configuration, the recess 1 of the lower mold 13
3b to fit the lower surface of the metal plate 10 into the upper mold 1.
2 is lowered, and the metal plate 1 is placed in the recess 12b of the upper die 12.
When pressing is performed while fitting the upper surface part 10c of the metal plate 10, the thickness of the metal plate 10 is guaranteed by the recesses 13b and 12b, and the chevron-shaped protrusion 12d of the upper die 12 is pressed.
is V on the top surface 10c of the tip 10a of the metal plate 10.
It literally engulfs me.
