Abstract

A clamping system for a press brake includes an elongate beam having a receiving space for receiving a part of a bending tool, and a clamping element movable between a first position in which it may engage on the bending tool for clamping it in the receiving space, and a second position for releasing the bending tool. The clamping system includes a pressure chamber fillable with a fluid, and an actuating member for driving the engaging element in accordance with a pressure of the fluid in the pressure chamber.
