Abstract
PURPOSE: To prevent the change in the inside diameter size of the initial hold and make the nut seat face and nut hole highly accurate by penetrating the ring-form convex part of a coining die to the circumferential edge of the die.
CONSTITUTION: A guide post 6 is protruded above the central part of a coining die 4, and further a ring-form convex part 5 is provided to the top surface of the coining die 4 at the circumferential edge of the guide post 6. A plate 1 which has beforehand been pierced with an initial hole (a) is placed on the coining die 4 in alignment to the guide post 6, thence it is screw-down-pressed from above by a plane punch 7 to penetrate the ring-form convex part 5 to the bottom surface of the plate 1. Next, if a nut seat coin punch 2 is screwed down while the guide 3 is being inserted into the initial hole (a) of the plate 1 on the coining die 4 of the shape removed of the guide post 6, a nut seat (b) is formed in the opening of the hole (a) by its tapered part (t).
