Abstract:
1. Production unit for shaping workpieces of sheet metal between two press beams respectively equipped with first and second bending tools that are releasably affixed to the press beams, which press beams can be displaced relative to one another in a direction perpendicular to a working plane by means of a drive system and incorporating a control unit, wherein the control unit has a detection system and at least one detection means is provided, which is connected so as to communicate with the detection system in order to transmit data and/or signals, wherein the detection means is an integral part of the first bending tool and is provided in the form of a contact strip disposed in a housing compartment of the first bending tool, the contact strip projecting a distance beyond a tool tip of the first bending tool in the direction towards the second bending tool and mounted so as to be displaceable in the direction of motion of the press beam, wherein the tool tip of the first bending tool and the contact strip lie in a common plane that also includes a bending line along which the workpiece is bent.
