Abstract
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).
