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.
