Abstract

Perfeccionamientos en dispositivos para la laminación de tubos, dotados de un bloque metálico cilíndrico , preferentemente calentado, en el que se punzona y se estira el bloque metálico por medio de un mandril fijo y varios cilindros impulsados, colocados en forma inclinada, caracterizados porque el bloque metálico va guiado delante del intersticio de laminación en por lo menos un casquillo (4) impulsado o alojado en forma libremente giratoria, y cuyo diámetro interior es algo mayor que el diámetro exterior del bloque metálico a laminar
