APPARATUS FOR BENDING LONG-SIZE MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtained a bending apparatus of a long-size material with which semi-closed control for operating the six axes of an actuator on the basis of the deviation between a six-axis displacement command signal and a six-axis displacement feedback signal is performed and also which is provided with a simple and effective generating means of a correction value to the displacement commanding signal. SOLUTION: The bending apparatus of the long-size material to which the offset amount and the die angle of a movable die are given with the six-axis parallel linkage mechanism and which has a control device for operating the six-axis actuator on the basis of the deviation between the six-axis displacement command signal and the six-axis displacement feedback signal are given from the host device, is provided with a correction value generating means 200 for calculating the correction value of the displacement command signal for the next bending work and holding the calculated value .
