Abstract: A punching device for punching a workpiece includes a punching part and a broaching part. The punching part has a punching cutting edge that limits a punching cutting area, the punching part being intended to pierce the workpiece. The broaching part is intended to tear the workpiece later than the punching part, and includes at least a broaching tooth with a cutting edge that limits a cutting area which is greater than the punching cutting area.

Abstract: A notching tool for notching a workpiece, the notching tool having a notching punch and a die having an inner surface. The notching punch includes first and second punch portions, the first punch portion has a punch plane intended to hit the workpiece in a notching operation. The second punch portion protrudes from the punch plane in a direction which is substantially perpendicular to the punch plane, and is intended to contact the inner surface of the die when the notching punch hits the workpiece. The disclosure further provides a use of this notching tool and a method of notching which involves the operation of such a notching tool.

Abstract: Laser positioner for punching machines made up of two laser emitters (6) joined to a support (8) solidly fixed to the punching machine, wherein each laser emitter (6) emits a planar light beam, and has a rotational movement enabled in the direction of the emitted light beam (7), in such a way that the intersection of the two planar light beams (7) forms a line of intersection coinciding with the axis of action of the punch (4) of the punching machine.
