BENDING MACHINE HAVING COOLING DEVICE FOR FED WORKPIECE AND COOLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a cooling method capable of preventing at a comparatively low cost deterioration of accuracy of bending positioning that may possibly occur due to a slight dislocation of a holding part of a manipulator as a film adhesive is softened by a rise of a circumferential temperature to a certain degree when a workpiece having an abrasion-protective film on the surface thereof is fed into the bending machine. SOLUTION: The cooling method 15 comprises a means for cooling the pivotal point of the workpiece W by blowing air on a loading table 13 before the workpiece W having this kind of protective film is fed into the manipulator 12 of the bending machine 10.
