Abstract

E' descritta una pressa per estrusione la quale comprende un contenitore per una billetta ed un punzone, i quali sono muniti di rispettivi gruppi cilindro-pistone oleodinamici di azionamento. La pressa è inoltre dotata, per l'espulsione di aria accumulata durante l'estrusione di una billetta, di accumulatori idropneumatici destinati a contrastare la spinta del contenitore contro la matrice di estrusione e la spinta del punzone contro la billetta, durante l'estrusione di quest'ultima.An extrusion press is described which comprises a container for a billet and a punch, which are provided with respective hydraulic cylinder-piston drive units. The press is also equipped, for the expulsion of air accumulated during the extrusion of a billet, of hydropneumatic accumulators intended to counteract the thrust of the container against the extrusion die and the thrust of the punch against the billet, during the extrusion of the latter.
