Patent ID: 7721586

Claim:
A tool holder for a press brake having a pressing axis, the tool holder comprising: a) a tool-mount channel configured for receiving a tang of the tool, the tool-mount channel being bounded by two confronting walls of the tool holder; b) a seating member mounted on the tool holder so as to be moveable between an open position and a closed position, wherein a leading end region of the seating member extends into the tool-mount channel when the seating member is in its closed position, said leading end region of the seating member having at least one contact surface to bear forcibly against a desired surface on the tang of the tool so as to deliver to the tool a force having a seating component that is at least generally parallel to the pressing axis; c) a driver adapted for selective operation by actuating the driver at a desired time, in response to which the seating member moves to its open position, wherein such movement involves at least part of the seating member moving away from the tool-mount channel; and d) a push plate operably coupled to the driver, the push plate being mounted on the tool holder so as to be movable between first and second configurations.
