A three-dimensionally shaped round metallic wire having a cross-section non-circular portion in a predetermined portion without performing additional processing and having specified dimensional accuracy and accuracy of form. In an intermediate step in which the round metallic wire is processed in a predetermined three-dimensional shape, a cross-section non-circular portion forming machine 20 which forms the cross-section non-circular portion having a non-circular cross-sectional shape in at least one position is included. At the time of bending, the cross-section non-circular portion is held by a wire holding portion of a bending machine 30, and the bending is performed in the predetermined three-dimensional shape. Holding the cross-section non-circular portion causes relative rotation between the cross-section non-circular portion and the wire holding portion to be suppressed as compared with a case of the cross-section circular shape. Accordingly, bending accuracy in the three-dimensional shape for the round metallic wire is improved.

A wire forming apparatus 1 comprises a rotary table 22 that is rotatably supported by a table body 21, a slide tool unit 100A that is attached to the rotary table 22 and supports a slide tool T1 capable of sliding toward a wire guide, and a tool slide mechanism 60 that is supported by the table body 21 and transmits a driving force for sliding the slide tool T1 to the slide tool unit 100A. The tool slide mechanism 60 has a single motive power transmission member 61 that is rotatably supported by the table body 21, and a driving force generated by a rotation of the motive power transmission member 61 is transmitted, in common, to a plurality of slide tools T1 attached to the rotary table 22.

An apparatus and method for calibrating an automated wire bending machine is provided that includes a camera system comprising a camera and a lens configured with a focal plane fixedly positioned relative to a bending surface provided on the automated wire bending machine. The disclosed apparatus and method further includes a processor device configured to interpret images captured by the camera system. The apparatus and method measures an actual angle formed in a wire while a bent portion of the wire is substantially within the focal plane of the camera system, and a memory device stores values generated during a calibration sequence of the automated wire bending machine. The values correspond to the actual angle and a target angle provided for the calibrating of the automated wire bending machine.

The combined machine has vise means in the support bench. The slider also comprises, on the work plane, a bending unit associated with the curving unit and the vise means are positionable in a direction orthogonal to the axis of movement.

A method produces a bent part from an elongate workpiece, in particular from a wire or a tube from round, flat, or profiled material, by a bending machine, the workpiece is fed to a bending unit of the bending machine, wherein the bending unit has a bending head which by a Z-drive is displaceable in a manner parallel with a bending head axis and has a bending tool which by a bending drive is rotatable about a bending axis. A fed portion of the workpiece by operating movements of the bending head is formed to a two-dimensionally or three-dimensionally bent part.

An orthodontic wire bender robot to be used in the manufacture of orthodontic prostheses, having a cartesian type displacement frame that allows moving the bending head of the equipment along the X, Y and Z-axes, in order to enable the robot to execute bends by torque, performing horizontal, vertical and sagittal compensations so that the shaped orthodontic wire presents an incline on its faces at certain angle and segment in order to execute frontal rotation stresses.

A device for bending wire includes a first plate with upper and lower surfaces and a center aperture extending therebetween. A cavity is formed in the upper surface that includes opposing sidewalls with a separation that decreases as they extend towards the center aperture and decreases as they extend up from a bottom surface of the cavity. A pin assembly disposed in the cavity includes a second plate having a pin extending from a top surface and having opposing side surfaces with a separation that decreases as they extend towards the center aperture and decreases as they extend up toward the top surface. A shaft extends through the center aperture and terminates in a bend head having a wire aperture and first and second bend surfaces adjacent the wire aperture. A first motor is configured to rotate the first plate about the shaft in opposing first and second rotational directions.

A device for bending wire that includes a pin extending from an upper surface of a plate, a shaft extending through a center aperture of the plate and terminating in a bend head, a sleeve rotatably disposed around the shaft, a first motor for rotating the plate about the shaft, and a second motor configured to move the plate between extended, retracted and intermediate positions along the shaft. The plate positioned in the extended position and rotating causes the first pin to travel in front of a wire aperture of the bend head. The plate positioned in the intermediate and the retracted positions and rotating causes the first pin to travel underneath the wire aperture. The plate positioned in the retracted position causes the plate to engage with the sleeve such that rotation of the plate causes rotation of the sleeve.
