Abstract

Il dispositivo, destinato ad un laminatolo a quattro cilindri, con due cilindri di lavoro (4, 5) e due cilindri di appoggio (8, 9), per equilibrare ed inflettere i cilindri di lavoro presenta cilindri idraulici (22-25), i quali sono montati in blocchi di sostegno (12, 13) che sono disposti nelle finestre (3) delle gabbie (2) dei cilindri e recano guide (14) per gli inserti (6, 7) dei cilindri di lavoro. Pistoni di posizionamento (21) del cilindri idraulici (22-25) agiscono sugli inserti (6, 7) dei cilindri di lavoro attraverso staffe (26) disposte al centro. Gli assi longitudinali (22a-22a, 23a-23a) delle due unità (22, 21; 23. 21) cilindro-pistone per la regolazione dell'inserto superiore (6) del cilindri di lavoro, e gli assi longitudinali (24a-24a, 25a-25a) delle due unità (24, 21;25, 21) cilindro-pistone per la regolazione dell'inserto inferiore (7) del cilindri di lavoro sono disposti l'uno diametralmente opposto all'altro su un cilindro fittizio (32), il cui asse longitudinale (32a-32a) rappresenta la retta di intersezione del piano assiale (15-15) dei cilindri con il piano di mezzeria (33-33) ortogonale dei supporti (34) dei cilindri, e le due coppie di unità (22, 21; 23, 21 e 24, 21; 25, 21) cilindro-pistone sono montate nei blocchi di sostegno (12, 13) ruotate l'una relativamente all'altra in ragione di un angolo .(Figura 2)The device, intended for a four-cylinder laminate, with two working cylinders (4, 5) and two support cylinders (8, 9), for balancing and inflating the working cylinders has hydraulic cylinders (22-25), the which are mounted in support blocks (12, 13) which are arranged in the windows (3) of the cages (2) of the cylinders and bear guides (14) for the inserts (6, 7) of the working cylinders. Positioning pistons (21) of the hydraulic cylinders (22-25) act on the inserts (6, 7) of the working cylinders through brackets (26) arranged in the center. The longitudinal axes (22a-22a, 23a-23a) of the two units (22, 21; 23. 21) cylinder-piston for adjusting the upper insert (6) of the working cylinders, and the longitudinal axes (24a-24a , 25a-25a) of the two cylinder-piston units (24, 21; 25, 21) for adjusting the lower insert (7) of the working cylinders are arranged diametrically opposite one another on a dummy cylinder (32 ), whose longitudinal axis (32a-32a) represents the straight line of intersection of the axial plane (15-15) of the cylinders with the center line (33-33) orthogonal of the supports (34) of the cylinders, and the two pairs of cylinder-piston units (22, 21; 23, 21 and 24, 21; 25, 21) are mounted in the support blocks (12, 13) rotated relative to each other by reason of an angle.
