Abstract:
A tool holder (10) for securely holding a forming tool (2) in its intended position on a press brake. The tool holder includes a tool holder plate (1) having first (7) and second (8) receiving surfaces oriented to respectively engage first and second mounting surfaces of a press brake tool, an actuator arm (12) movable toward and away from the tool holder plate and having a camming surface (14), a clamp (11) carried by the actuator arm and being movable with respect to the actuator arm toward and away from the respective receiving surfaces of the tool holder plate, and a cam (15) surface on the clamp oriented to be engaged by the camming surface of the actuator arm to receive force therefrom in response to engagement of the respective camming surfaces of the actuator arm and the clamp. The force thus received has substantial force vector components normal to the first and second receiving surfaces of the tool holder plate to press against these surfaces, respectively, the first and second mounting surfaces of the tool.
