Abstract (en)

[origin: EP0387121A1] Device for the instant clamping of a press-bending machine tool on it tool holder allowing its positioning and extraction from the front of the machine without having to displace the adjacent tools. <??>It comprises a clamp (6) articulated about a longitudinal pin (7), the said clamp having a shoulder (9) on which is hooked the heel of the tool which has an appropriate shape. When, after having hooked the tool, it is pushed from its position of equilibrium towards the rear, it drives the clamp in rotation by the contact of the surfaces (21 and 22), which operates a locking cam (12) which ensures the tightening of the clamp on the tool in the working position. In order to unclamp the tool, it suffices to retract the cam; the tool then remains hooked and can be extracted by forward pivoting. <??>The invention can be used for the attachment and immobilization of any suspended part or any part standing on a base. <IMAGE>
