Abstract

Perfeccionamientos introducidos en los útiles para la obtención por trefilado en prensa de tubos de diámetro interior constante y de diámetro exterior variable caracterizados por estar constituído el útil en cuestión por una aguja cónica cuyo pequeño diámetro se encuentra hacia el cabezal del prensado del cual dicha aguja es solidaria o no y cuyo diámetro mayor termina en una parte cilíndrica.Improvements introduced in the tools for obtaining tubes of constant internal diameter and variable external diameter by drawing in a press, characterized by the fact that the tool in question is constituted by a conical needle whose small diameter is towards the pressing head of which said needle is joint or not and whose larger diameter ends in a cylindrical part.
