Abstract:
A method and equipment for bending a work to the extent of a target bending angle, including a first process of bending to bend a work with a ram driven by a two-shaft system having a pair of right and left drive mechanisms to the extent of the quantity of motion for each shaft corresponding to the target bending angle, a measurement process to measure the bending angles at both ends of the work bent in the first process of bending, a correction process to correct the quantity of motion for each shaft according to each error between the target bending angle and the respective bending angles at both ends of the work measured in the measurement process, and a second process of bending to bend the work with the ram driven by the two-shaft system in which each shaft is actuated by each drive mechanism to the extent of the quantity of motion for each shaft corrected by the correction process, all of the above processes being performed in series.
