This invention relates to a device for locking tools on press brakes, comprising: a tool holder (2) which can securely engage with an upper beam (3) of a press brake and comprises a first clamping surface (7); a clamping bracket (10) connected to the tool holder (2) and comprising a second clamping surface (14) facing the first clamping surface (7), in such a way as to delimit a housing for the shank (15) of a tool (16) to be locked in place; a wedge (22) interposed between the bracket (10) and the tool holder (2) at an upper end of the bracket (10) opposite to the tooth (20). The wedge (22) can move relative to the bracket (10) and is slidably connected to the tool holder (2) in a sloping plane (P). A grub screw (24) pushes the wedge (22) away from the bracket (10) and against the tool holder (2), causing the bracket (10) to perform a roto-translating movement in such a way as to lift the tool (16), bring it into contact with the tool holder (2) and clamp it between the first and second clamping surfaces (7, 14).

A device for locking of dies on press brakes comprises a lower beam (2) having a rest surface (7) for a die (3) and a first clamping surface (9) extending in a transverse direction from the rest surface (7). A clamping plate (13) can be linked to the lower beam (2) on the side opposite to the first clamping surface (9) relative to the rest surface (7) and has a second clamping surface (14) facing the first clamping surface (9), so as to delimit a seat for the die (3). At least one pin (17) is fastened to the lower beam (2) and is inserted with a predetermined clearance, in a respective hole (18) formed in the clamping plate (13), in such a manner that the clamping plate (13) is free to oscillate in a plane transverse to the longitudinal extension of the lower beam (2). Spring means (22) is interposed between the clamping plate (13) and the lower beam (2) and located at an end (23) of the clamping plate (13) opposite to the second clamping surface (14) relative to the pin (17), to push the end (23) away from the lower beam (2) and push the second clamping surface (14) towards the first clamping surface (9) and the die (3).
