<p>An improved bending control method for a hollow punch (20) production plant, the hollow punch (20) production plant comprising a bending station (10) wherein one of said hollow punches (20) is bent with a series of bending operations driven by a control unit; the method comprises at least one bending detection phase of the hollow punch (20), said detection being transmitted to the control unit which drives the subsequent bending operations. The invention also relates to an improved bending control device (22) for a hollow punch (20) production plant, wherein a control unit drives a relative movement between a bending tool (14) and a gripping element (12); said control device (22) comprises a bending detection unit (24) for the hollow punch (20), the bending detection unit (24) supplying information to the control unit.</p> |
