Devices, systems and methods for automated wire bending

摘要

Devices, systems and methods are disclosed which relate to a wire bending apparatus capable of both on and off-plane nose and mandrel bends. Exemplary embodiments of the present invention incorporate a center turret cluster with a plurality of radii possible, a nose-bending mandrel, and a mandrel-bending mandrel. This apparatus forms a bending head that is attached to a CNC wire bending machine. This combination allows increased flexibility in forming complex wire forms and cuts down secondary operations, such as operations from robot arms, sometimes associated with CNC wire bending. In addition, the turret cluster position in the center allows for bending support with mandrel bends or nose bending on the back side of the bending head, usually 180 degrees away from the normal bending area. This allows the manufacturing of double end-loop forms without the addition of external clamps or robotic manipulation.

主权项

1. A method of wire bending of the type using a CNC wire bending machine comprising:
feeding a wire through a turret cluster in a forward direction along a centerline; nose-bending a first end of the wire; mandrel bending a complete loop at the first end of the wire; and off-plane bending the wire by mandrel bending a complete loop at a second end of the wire, wherein the nose bending and mandrel bending are performed by mandrels that are capable of raising, lowering, and spinning independently of the turret cluster; wherein each bend is performed without having to remove the wire from the CNC wire bending machine.
