Abstract (en)
[origin: US2005160781A1] The invention concerns a bending machine comprising a machine frame, and upper bar and a lower bar mounted on the frame and mutually mobile, a bending bar mounted on the frame, a bending bar mounted on the frame and mobile relative to the frame, to the upper bar and to the lower bar, said bending bar being provided with a support and a bending tool pressing on said support via a bending device actuated by a control unit. The invention aims at making the bending adjustment faster and more accurate. Therefor, said bending device is equipped with an adjusting device capable of being used during a bending operation; the adjusting device, which is actuated by the control unit, can be controlled during a bending operation; at least one sensor associated with the control unit enables detection, through the adjusting device of an adjustment performed by the control unit. For a given bending operation, the control unit determines at least one bending parameter for the bending device, the bending bar tool being set in a substantially flexure-free position at the end of the bending operation.
