ROLLER BENDING MACHINE AND METHOD FOR BENDING ELONGATED WORWPIECES

摘要

Roller bending machine for bending an elongated workpiece (P) comprises: a first roller (2) suitable for acting on a first face (3) of the elongated workpiece (P); actuator means (4) coupled with the first roller (2) and configured for moving the first roller (2) along a first plane (P1) lying transversely to an advancement direction (DA) for the elongated workpiece (P); a second roller (5) and a third roller (6), arranged on sides opposite with respect to the first transverse plane (P1) and suitable for acting on a second face (7) of the elongated workpiece (P) opposite to the first face (3), further actuator means (8, 9) configured for moving the second roller (5) and the third roller (6) to vary the respective distance (D5; D6) thereof from the first plane (P1), the second roller (5) and third roller (6) being configured for moving, by further actuator means (8, 9), along respective trajectories (T1, T2) approaching the first roller (2) that extend transversely to the first plane (P1). The method is also provided for bending an elongated workpiece (P) by the aforesaid roller bending machine (1).
