DISPOSITIF D'ACTIONNEMENT DES OUTILS SUPÉRIEURS DE PRESSE À TÔLE D'UNE MACHINE INDUSTRIELLE POUR LE PLIAGE D'ÉLÉMENTS MÉTALLIQUES

摘要

The invention relates to an actuating device (10) for actuating a contractible element (100) for bending means (4) of an industrial machine (1) for bending metal elements provided with a lower component (44) and an upper component (46) apt to move relative to each other from a first position (P1) to a second position(P2), the actuation device (10) comprising a connecting plate (30) configured to be connected to the lower component (44) of said contractible element (100). A rack and pinion gear unit (20) comprises a pinion (21) having an axis (X), at least a first rack (22) and a second rack (23) actuated simultaneously by the pinion (21). The first rack (22) is configured to be fixed to the upper component (46) and the second rack (23) is configured to be coupled to the connecting plate (30).
