ABSTRACT:
The present invention relates to a device for replacing upper and lower dies in a bending processing machine, such as, for example a press brake. According to the invention, long upper and lower dies used in a bending processing machine are comprised of freely dividable sections that can be taken apart and recombined for convenient storage in an adjacent die exchange device. In the die exchange device, die holders are formed on the insides of a number of link members which are pivotably linked in a loop.
