<p>The object of the present invention is to provide a die which enables automated press working in such a way that even in a die having a slant face working cam (104), feeding and taking-out of works are not obstructed by an actuating cam (112) fixed to a lower die. The present invention proposes a die having triple- structural hanging cams comprising: a slide cam base (5) which is fixed to a base (2) of a upper die (1) and is formed into a polyhedron guide portion (43) at its end; a slide cam (7) which holds the polyhedron guide portion (43) of the slide cam base (5) and slides the polyhedron guide portion and carries a machining member like a punch (6); an elastic body (8) which is interposed between the slide cam base (5) and the slide cam (7) and energizes the slide cam; and an actuating cam (9) which contacts with the slide cam (7) to drive it, a plurality of positioning grooves (10) are formed on an undersurface of the actuating cam (9), said die further comprises positioning protrusions (12) which are provided in lower die (11) portions facing said positioning grooves (10) of the actuating cam (9) and engage said positioning grooves. <IMAGE></p> |
