METHOD TO CHECK AND CONTROL A ROLLER BENDING MACHINE FOR CONTINUOUSLY BENDING AN ELONGATED WORKPIECE AT VARIABLE CURVATURE RADII, AND MACHINE SO CONTROLLED |
摘要 |
A method to check and control a roller bending machine for continuously bending an elongated workpiece at variable curvature radii in a bending machine using a series of rollers for bending, comprises the steps of measuring the distance of the elongated work piece in a point that is situated downstream the series of rollers for bending in successive instants, calculating a curvature radius of each bend section of the elongated workpiece, comparing the calculated curvature radius with the desired curvature radius and determining a difference between them, calculating the change of position to which an upstream roller has to be subjected in order to annul such a difference and operating the upstream roller on the base of the calculated change of position. A machine embodying the method is also described. |
