Patent ID: 11167336

Abstract:
An actuating device for actuating a contractible element for a bending element of an industrial machine for bending metal elements comprises a lower component and an upper component apt to move relative to each other from a first position to a second position, the actuation device including a connecting plate configured to be connected to the lower component of the contractible element. A rack and pinion gear unit is also set out and includes a pinion having an axis, at least a first rack and a second rack actuated simultaneously by the pinion. The first rack is configured to be fixed to the upper component and the second rack is configured to be coupled to the connecting plate. The pinion is operable in a first direction of rotation to move the first rack and the second rack transverse to the axis in opposite directions. The pinion is operable in a second direction of rotation, contrary to the first one, to move the racks in opposite directions towards a second position.
