Abstract

PURPOSE:To reduce a working time and to obtain a high working precision by constituting work supporting bases so that they can rotate and rock round a work. CONSTITUTION:When the work 9 is fixed to the work supporting bases 3 to give a start command, a controller starts operation, an internal gear 16 is rotated, bending units 4 are moved, an oscillating die is oscillated in good timing and the work 9 is folded into an arbitrary symmetrical shape and formed. In this case, the bending units 4 are controlled so that they move in sequence from a side far from the work supporting bases 3 to a side near them. Thus, as soon as the bending units arrive at a working position, bending can be performed and the working time can be reduced.

(Problem to be solved) However, with this conventional method, the bending unit is rotationally controlled, which increases the number of axes that must be controlled during bending, which increases costs. Moreover, since the bending head must be driven to bend the workpiece after controlling the posture of the bending unit, there is a problem in that the time required for each bending process becomes longer. With conventional systems that rotate the unit lift to change the bending direction of the workpiece, it is difficult to achieve rotational accuracy of the bending unit, and it is not possible to obtain a sufficiently large fixing force to the bending head, which is the reference point during bending. Therefore, there was a problem in that it was difficult to increase the processing accuracy.
