Abstract: 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.

Abstract: The use of an accumulator attached to a chamber of a cylinder allows for the reduction in pressure spikes in constant force hydraulic control systems. Constant force hydraulic control systems often use a differential pressure valve that may have a reaction time of up to one second. By using the accumulator, pressure spikes which might have occurred in the past can be smoothed out and reduced, thus preventing damage to a workpiece or agricultural product. Additionally, by using two cylinders of different sizes, in which one of the cylinders has a barrel end with the approximately the same area as the rod end of the larger cylinder, coordination of devices attached to the cylinders can be maintained without a mechanical link when the hydraulic control system is in a manual mode.
