| description | The proposed process for the hot extrusion of metal with the active assistance of friction forces involves placing the pre-heated blank (1) in a chamber (3) and forcing it through the die (5), which determines the shape and geometrical dimensions of the finished article, with the aid of a ram (4) while moving both simultaneously; the speed Vc of the chamber (3) is about 1.05 to 1.3 times greater than the speed VR of the ram (4). The hydraulic extrusion press has a crosspiece (8) on which is mounted an auxiliary cylinder whose inner cavity (20) is hydraulically connected to the inner chamber (19) of the stabilization chambers on the rear transverse beam (12) of the press, while the ram (4) is mounted on the plunger (22) of the auxiliary cylinder and enters the chamber (3) accommodating the blank (1); the die (5) with the hollow extrusion die (6) is situated on the other side of the chamber (3), the extrusion die being securely attached to the front transverse beam (11) of the press.
L'invention concerne un procédé d'extrusion à chaud de métal avec l'aide active de forces de friction qui consiste à placer le flan préchauffé (1) dans une chambre, à l'introduire de force dans la filière (5), ce qui permet de conférer des formes géométriques à l'article fini, à l'aide d'un fouloir (4), la chambre et le fouloir se déplaçant simultanément; la vitesse Vc de la chambre (3) est d'environ 1,05 à 1,3 fois supérieure à la vitesse VR du fouloir (4). La presse d'extrusion hydraulique présente un élément transversal (8) sur lequel est monté un cylindre auxiliaire dont la cavité interne (20) est reliée hydrauliquement à la chambre interne (19) des chambres de stabilisation sur la poutre transversale arrière (12) de la presse, alors que le fouloir est monté sur le piston (22) du cylindre auxiliaire et entre dans la chambre (3) renfermant le flanc (1); la filière (5) et un tube d'extrusion sont placés de l'autre côté de la chambre (3), ledit tube d'extrusion étant fixé solidement à l'élément transversal avant (11) de la presse. |
