Abstract

SUR L'ENVELOPPE EXTERIEURE102 DE LA CAPSULE101, ON FORME UN EVASEMENT 103 DIRIGE VERS L'EXTERIEUR ET A L'ENCONTRE DE LA CONTRACTION SE PRODUISANT LORS DE LA COMPRESSION ISOSTATIQUE, CET EVASEMENT ETANT CALCULE POUR ETRE ELIMINE COMPLETEMENT PAR CETTE CONTRACTION. SUR LA FACE AVANT ETOU LA FACE ARRIERE DE LA CAPSULE101, ON PREVOIT UNE PIECE RAPPORTEE130, 140 MOULEE EN UNE MATIERE PLEINE ETOU EN POUDRE. L'INVENTION EST UTILISEE POUR L'EXTRUSION D'ARTICLES METALLIQUES ALLONGES TELS QUE DES TUBES EN ACIERS RESISTANT A LA CHALEUR POUR ECHANGEURS DE CHALEUR.ON THE EXTERIOR ENVELOPE102 OF THE CAPSULE101, A FLARE 103 IS FORMED DIRECTED TO THE EXTERIOR AND AGAINST THE CONTRACTION OCCURRING DURING ISOSTATIC COMPRESSION, THIS FLARING BEING CALCULATED TO BE COMPLETELY ELIMINATED BY THIS CONTRACTION. ON THE FRONT SIDE AND OR THE REAR SIDE OF THE CAPSULE101, A FITTED PIECE 130, 140 MOLDED IN A SOLID OR POWDERED MATERIAL ARE PROVIDED. THE INVENTION IS USED FOR THE EXTRUSION OF ELONGATED METAL ARTICLES SUCH AS HEAT-RESISTANT STEEL TUBES FOR HEAT EXCHANGERS.
