ABSTRACT:
A tool support structure for a press brake has a plurality of independently movable clamps, each of which is independently spring biased for linear movement into a clamped position wherein the clamps secure a tool in the structure. The clamps are about one inch long to ensure full, continuous clamping contact with the tool. Release of the clamping action is accomplished by either a hydraulic system or a wedge system which, when activated, overcomes the bias force and moves the clamping members to the release position wherein the tool may be removed from the structure.
