Title (EN) HIGH-SPEED HYDRAULIC PRESS
(FR) PRESSE HYDRAULIQUE A GRANDE VITESSE
Abstract:
(EN) A high-speed hydraulic press comprising a high-speed hydraulic cylinder (3) and a slide (6) adapted to be moved vertically by means of the high-speed hydraulic cylinder, the high-speed hydraulic cylinder and slide being provided on an upper part of a press main body constituted by a C-shaped frame (1a), wherein a manifold block (4) is directly mounted on a front face of the high-speed hydraulic cylinder and wherein a control valve (8) is mounted on the manifold block, whereby hydraulic fluid is supplied to the high-speed hydraulic cylinder via a passageway inside the manifold block by controlling at least one of the flow rate and pressure of the hydraulic fluid by means of the control valve.
(FR) L'invention porte sur une presse hydraulique à grande vitesse comportant un vérin hydraulique à grande vitesse (3) et un coulisseau (6) se déplaçant verticalement sous l'effet du vérin, ledit vérin et ledit coulisseau se trouvant à la partie supérieure du corps principal d'une presse à bâti en C (1a) sur lequel est monté directement un bloc de tubulures (4) placé sur la face frontale du vérin et sur lequel est montée une soupape de commande (8). Le fluide hydraulique parvient au vérin par un passage pratiqué dans le bloc de tubulures lorsqu'on règle au moins soit le débit, soit la pression du fluide hydraulique à l'aide de la soupape de commande.
