Abstract

L'INVENTION CONCERNE LE DOMAINE DU FORMAGE DE PRODUITS OU OBJETS PAR EXTRUSION A FROID. SELON L'INVENTION, ON FABRIQUE UN OBJET CREUX A SURFACE EXTERNE CYLINDRIQUE ET A SURFACE INTERNE POLYGONALE EN PREPARANT, DANS UNE PREMIERE ETAPE D'EXTRUSION, UNE EBAUCHE INTERMEDIAIRE L A SURFACE INTERNE CYLINDRIQUE 16 ET A SURFACE EXTERNE PRESENTANT UNE SERIE DE LOBES 17; DANS UNE SECONDE ETAPE D'EXTRUSION, METTANT EN OEUVRE UN POINCON A SECTION TRANSVERSALE POLYGONALE, CETTE EBAUCHE EST TRANSFORMEE EN LE PRODUIT FINAL RECHERCHE. CE PROCEDE CONSOMME MOINS D'ENERGIE QU'UNE EXTRUSION EN UNE SEULE ETAPE. APPLICATION: FABRICATION DE CLES A TUBE.
