Abstract

Perfeccionamientos en prensas para la extrusión indirecta de perfiles metálicos en general y de tubos para extruir de manera isotérmica con una placa de compresión dispuesta en el larguero de movimiento y una pieza de cierre que estanqueiza el taladro de un receptor de tocho, que se apoya en la placa, caracterizados porque la pieza de cierre y/o la placa de compresión están divididas transversalmente con respecto al eje de la prensa, y las partes son susceptibles de ser comprimidas divergiendo entre si de modo incapaz de ser desplazado mutuamente en el plano de división y limitado por miembros de compresión a lo largo del eje de la prensa con formación de una rendija de aire.
