Abstract:
A bending press system provided with a bending press with at least one bending station to mount a plurality of divided tools and;a tool housing device to house the divided tools used in the bending press, the divided tools including longer and shorter divided tools relative to one another; a tool exchange device that moves the divided tools between the tool housing device and the at least one bending station and mounts the divided tools on the at least one bending station, comprising: a first memory means that stores the housing positions of each divided tool housed in the tool housing device; a second memory means that stores a bending line length, a flange length and a bending angle of a bent product; a first computing means to determine the tool type to be mounted on the at least one bending station and a length of the at least one bending station based on the bending line length, flange length, and bending angle; a second computing means to determine the arrangement of each divided tool on the at least one bending station based on the tool type and length of the at least one bending station; an NC control means that controls the tool exchange device so that each determined divided tool is moved from the housing position of the tool housing device to the arranged position; and wherein in determining the arrangement of the divided tools, the second computing means gives priority to the longer divided tools.
