Adjustable die for a press brake

A die for a press brake comprising:

• a base;
• a first half portion and a second half portion of a mold, resting sliding on said base, between which the mold cavity is defined, the first half portion comprising a plurality of first plates parallel to one another, the second half portion comprising a plurality of second plates parallel to one another, said first and second plates extending in a transverse direction of the die and being alternated in a longitudinal direction (X) of the die, said first plates being disposed at a distance from one another to accommodate, between two consecutive first plates, at least a part of one of the second plates, said second plates being disposed at a distance from one another to accommodate, between two consecutive second plates, at least a part of one of the first plates;
• and
• a translation device configured to move the first half portion and the second half portion away from and toward each other, to vary the width of the mold cavity, said translation device comprising:
• a plurality of first guides defined within the first plates and a plurality of second guides defined within the second plates,
• a shaft disposed along the longitudinal direction of the die and engaged with the first guides and the second guides to slide along said first guides and said second guides when the first half portion and the second half portion are moved away from or toward each other,
• at least a first pinion and a second pinion mounted on said shaft,
• at least a first rack and at least a second rack respectively on a first plate and a second plate, said first and second racks being meshed respectively with said first and second pinions so that following rotation of the shaft in one direction or in the opposite direction, the two half portions are moved away from or toward each other.
