Abstract

L'INVENTION CONCERNE UN DISPOSITIF HYDRAULIQUE D'AMORTISSEMENT DES CHOCS DANS UNE PRESSE A DECOUPER. CE DISPOSITIF COMPREND DES ELEMENTS A CYLINDRE ET PISTON DISPOSES ENTRE LE BATI DE LA PRESSE ET LE COULISSEAU ET PRESENTANT CHACUN UNE CHAMBRE DE RECEPTION DE FLUIDE A VOLUME VARIABLE, DE LAQUELLE UN FLUIDE SOUS PRESSION EST EXPULSE LORS DU MOUVEMENT DU COULISSEAU VERS LE BATI PENDANT UNE OPERATION DE DECOUPAGE. UNE VANNE D'ARRET, SENSIBLE AU DEBIT, BLOQUE L'ECOULEMENT DU FLUIDE SORTANT DES CHAMBRES LORS D'UNE ACCELERATION DU MOUVEMENT DU COULISSEAU SE PRODUISANT A LA PERCEE DE LA PIECE. DOMAINE D'APPLICATION: PRESSES A DECOUPER, ETC.
