摘要： PROBLEM TO BE SOLVED: To provide a bending device capable of improving bending accuracy.
SOLUTION: In the bending device, 1 represents a sheet-like steel material, 2 represents an induction heating coil, 30 represents a feed mechanism for feeding a material to be bent into an axial direction, 21 represents a feed motor, 120 represents a bending arm mechanism, 13 represents a clamper detachably clamping the steel material 1 at the outlet of the induction heating coil 2, 14 represents a rotary arm holding the clamper 13 and capable of turning on an rotation shaft 15, 16 represents a rotary table, which is fixed to the rotation shaft 15, and to which a base part 17 of the rotary arm 14 is fixed, 40 represents a driving motor for rotatably driving a rotary table, and 51 represents a synchronization controller, which synchronously controls the feed motor 21 and the a rotary motor 40 and makes the feeding speed of the steel material 1 fed by the feed motor 21 agree with the linear velocity of rotation of the clamper 13. Further, the synchronization controller 51 monitors the output of a torque sensor 50 and performs constant torque control so that the output torque of the feed motor 21 is constant.
