Abstract

Perfeccionamientos en prensas para extrusión de perfiles en general y tubos para la iniciación de extrusión indirecta y la extrusión indirecta, que consta de un larguero de cilindros, de un larguero opuesto y de columnas que unen a éstos, así como de un larguero de movimiento unido con un pistón de prensa y un receptor de techo, en cada caso con disposiciones de desplazamiento de larguero de movimiento y de receptor de techo accionables hidráuilicamente en cada caso independientemente entre sí, caracterizados porque para aumentar la fuerza de extrusión en cualquier lugar y en cualquier momento a igual posición constante del larguero de movimiento y del receptor de techo un con relación al otro, ambos pueden ser acoplados hidráulicamente con cierre de fuerzas mediante elementos de sujeción y los cilindros de las disposiciones de desplazamiento pueden ser conectados con el pistón de prensa.
