Abstract: A method of feeding an elongate workpiece to a forming machine includes: providing first and second feed units, wherein each of the feed units has a receiving device that receives a workpiece stock in a coil, and a straightening device downstream of the receiving device that straightens the workpiece before it enters the forming machine, wherein the first and second feed units are arranged on a common platform movable between first and second working positions, wherein, in the first working position of the platform, the first feed unit is arranged in a working position suitable for transferring workpiece portions to the forming machine, and the second feed unit is arranged in a setting-up position, and, in the second working position of the platform, the second feed unit is arranged in the working position and the first feed unit in a setting-up position.

Abstract: A bending machine that produces complex bent parts from straight wire rods includes computer-numerical control unit; a transport system that transports successive wire rods along a transport path, wherein the transport system has a plurality of workpiece-receiving devices each for receiving a single wire rod; a plurality of workstations arranged along the transport path, wherein at least two of the workstations are configured as bending stations, wherein at least one bending station comprises a bending unit configured as a rotary draw bending unit.

Abstract: A method of producing shaped parts includes drawing wire from a wire stock and feeding the wire to a processing machine; straightening the wire in the wire processing machine; and separating shaped parts of a predefinable wire length from the straightened wire, wherein, to separate a shaped part from the fed wire, at a separating position provided for separation, the wire is first notched in at least one notching operation from two opposite sides by notching tools such that a tapered wire cross section remains between opposing notches at the separating position, and in a dividing operation, the notched wire is separated at the separating position in a region of the tapered wire cross section by engagement of two dividing tools on opposite sides of the wire and their synchronous feed in opposite feed directions perpendicularly to the wire axis until the wire material is severed at the separating position.

Abstract: A device for producing a loop at the end of a coil spring has a gripping unit with gripper jaws for retaining the spring in a processing position. The gripping unit is movable to and from the processing position and at least one section of an end turn of the spring protrudes over the gripper jaws. A first slewing gear unit has an output shaft and a coupling section for detachable coupling of a tool for the forming of a loop on the spring through upward bending of the end turn section protruding over the gripper jaws. A counter block attached laterally to the travel direction of the gripping unit is movable over the section of the end turn of the spring protruding over the gripper jaws and has a bending edge as a bending form for producing a loop with the tool.
