Abstract (en)

[origin: WO2019001982A1] In a method for producing a bent part from an elongate workpiece, more particularly from a wire or tube made of round, flat or profiled material, by means of a bending machine, the workpiece is fed to a bending unit of the bending machine, wherein the bending unit has a bending head (180) that can be moved by means of a Z drive parallel to a bending head axis (185) and has a bending tool (184) that can be rotated about a bending axis by means of a bending drive. A fed section of the workpiece is shaped by means of working movements of the bending head into a two-dimensionally or three-dimensionally bent part. The finished bent part is separated from the fed workpiece material in a cutting operation by means of a cutting device (150) that is separate from the bending head. The cutting device (150) is actuated by a working movement of the bending head (180) parallel to the bending head axis (185) or a rotary movement of the bending tool (184) about the bending axis by means of a transmitting device (250). For this purpose a movable component (160) of the cutting device (150) is coupled by means of a transmitting device (250) to the Z drive or bending drive on the bending machine to transmit forces and torques such that the cutting device can be actuated via the coupled drive. This eliminates the need for a separate drive for the cutting device (150).
