Method and wire processing machine that produces prepared shaped parts
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.
The invention relates to a method and a wire processing machine for producing straight or bent shaped parts from insulated flat material (W), in which the insulated flat material is drawn from a material supply by means of a drawing-in device and is processed in the wire processing machine to form a straight or bent shaped part consisting of insulated flat material. The shaped part is then severed from the supplied insulated flat material in a cutting operation. Before the shaped part is severed, a part of the insulation layer (I) which surrounds the carrier material (T) is removed from the electrically conductive carrier material (T) in at least one section of the insulated flat material (W) in an insulation stripping operation. To this end, insulation stripping tools (310-1, 310-2) on opposite side faces of the flat material are positioned towards the side faces into a working position in which the insulation stripping tools (310-1, 310-2) are engaged in the insulation layer, and the insulation stripping tools and the flat material are moved relative to each other parallel to a passage axis. Synchronously with the positioning of the insulation stripping tools, at least one supporting element (610-1, 610-2) of a supporting device is positioned towards the flat material (W) on each side of the flat material and is supported by a supporting face on the flat material in the immediate vicinity of an engagement position of the insulation stripping tool when the insulation stripping tool is in the working position. Any vibrations in the engagement region between the insulation stripping tool and the flat material can be damped thereby. The insulation-stripped sections of the carrier material provided for contacting can thus obtain a largely undamaged, clean surface.

METHOD FOR PRODUCING A BENT PART AND BENDING MACHINE FOR PERFORMING THE METHOD
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).
Disclosed is a method for producing a bent part from an elongated workpiece (110), in particular from a wire or a tube, by means of a bending machine, which has a bending head (180) with a bending tool (184) for acting on a first workpiece portion (110-1) to be bent, according to which method the bending tool can be turned about a bending axis (185) by means of a bending drive controlled by a control device. First, a workpiece portion that is to be provided with a bend is brought into a starting position in the engagement region of the bending head (180). Next, the bending tool (184) is brought into contact with the first portion at a distance from the bending axis. Thereafter, in a bending operation, a bend is produced between a second portion (110-2), which is not to be bent, and the first portion (110-1) by turning the bending tool (184) about the bending axis (185). Subsequently, using a measuring system equipped with a camera and designed for the contactless capture of data relating to the geometry of the bent part currently being produced, an angular measurement value is taken, representing the actual bending angle produced by the bending operation. The camera captures an image field (252) that contains the bending head (180), wherein image information from the image field is evaluated for the determination of the measured value for the angle.

The bent part is then separated from the supplied insulated flat material in a cutting operation. In at least one section of the insulated flat material, some of the insulation layer is removed from the electrically conductive support material in an insulation-stripping operation. In the method, the insulation-stripping operation is carried out in a continuous process on the flat material guided in the bending machine, by means of an insulation-stripping device (200) integrated in the bending machine (100), before the bent part is separataed from the supplied flat material.
