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.

The invention relates to a die for a punching device. The die comprises a die base body and a workpiece support body, which is provided on the die base body, to support a workpiece to be machined as well as a cutting to length mechanism for cutting a workpiece part of the workpiece to length. The cutting to length mechanism has a cutting to length element and a counter-cutting to length element for cutting to length interaction with the cutting to length element by several cutting to length strokes. The cutting to length element and the counter-cutting to length element can be displaced relative to one another between a cutting to length position, in which the cutting to length element and the counter-cutting to length element interact with one another so as to cut to length, and an open position, in which the cutting to length element and the counter-cutting to length element are spaced apart from one another. Furthermore, the die has a guide mechanism to guide the workpiece part.

An adjustment device of a punching device punches a workpiece on a die so that the workpiece is punched into a predetermined shape. The adjustment device includes a first drive mechanism that moves the punch or the die in a direction orthogonal to a punching direction, and a controller connected to the first drive mechanism. The controller brings the punch and the die into contact with each other by moving the punch or the die in four orthogonal directions in a plane perpendicular to the punching direction from an initial position where the punch is inserted into the punching die. The controller causes the first drive mechanism to move the punch or the die to a center position where a central axis of the punch and a central axis of the die are aligned with other.
