Die exchange apparatus for the use of a press brake.

摘要

A press brake (1) has upper dies (13) and lower dies (11) so as to be capable of attaching and detaching with an upper die exchange apparatus (16) and a lower die exchange apparatus (17) to a machine body of the press brake (1). And, the upper die (13) and the lower die (11) comprise the combination of divisional die chips. The storing of dies is performed with those die chips. And, the face width of the upper die chips is determined and combined according to size of a workpiece to be processed from the upper die chips.
