Abstract
In a multiple tool for a punch press, a plurality of punches (57) are arranged circularly so as to be movable up and down within a stripper guide (41) provided also movably up and down in an upper die holding member (15) of the punch press; a punch driver (77) is disposed so as to be rotatable and movable up and down in a central hole (75) within the stripper guide (41); and a projecting portion (97) is formed in the punch driver (77), for striking any one of a plurality of the punches. Further, an indexing device is mounted to rotate the punch driver (77) so that the projecting portion (97) can be indexed over any required punch (57A), for instance. Since only one required punch of a plurality of the punches can be struck without moving the striker, the multiple tool is simple in structure, high in precision, and low in cost.
