摘要： The two turrets (6, 7), carrying a plurality of punch-die pairs (8, 9), are rotatable to carry a punch-die pair (8, 9) to a work station (3) and, simultaneously, another punch-die pair (8, 9) to a changeover station (63). A magazine (31) of punch-die pairs (8, 9) comprises at least one pair of discs (33, 34) joined to each other and carrying a series of punch-die pairs (8, 9). The discs (33, 34) are selectively rotated to take a predetermined new punch-die pair (8, 9) to a collection station (65). At least one exchange arm (48, 49) is rotated by a corresponding servomotor (59) and carries at least one gripper element (53, 54), axially and radially moveable with respect to the arm (48, 49), independently of each other.

摘要： The machine includes two turrets (6, 7) carrying a plurality of punch-die pairs (8, 9), a magazine (31) for these pairs, and a device (32) for changing over the pairs. This device (32) is formed from at least one changeover arm (48, 49) having two gripper elements (53, 54), each comprising a pair of jaws (131) operable by a common actuator (142, 143). The two jaws (131) are provided with a through-pin (138) and are each engagable in a pair of channels (136, 137), perpendicular to each other, carried by a flange (89, 90) of the punch (8) or the die (9). When the gripper element (53, 54) moves parallel to the axis of the punch (8) or the die (9), a first channel (136) of the pair is disposed axially and has a quadrangular section, while the other channel (137) is tangential and has a triangular section.
