Abstract

Nuevo método y máquina para fabricación de tubos en frio, caracterizado por curvar la chapa en forma virtualmente cilíndrica en matrices y prensas "ad-hoc" y rectificar el radio de curvatura en una máquina que presenta una pluralidad de rodillos machi-hembrados cuyas salientes anulares coinciden con el espacio comprendido entre los bordes de la chapa dispuestos en mutua aproximación; estando el caño premoldeado sometido a la tracción de un elemento motriz con la intercalación de elementos de acople desmontables, capaces de obligar el tubo a través de una matriz trefiladora en las inmediaciones de cuya zona de remate presenta una abertura longiforme, coincidente con la abertura del tubo, proyectándose en dicha zona el electrodo de un equipo de soldadura cuya masa está dispuesta dentro del conducto del tubo, y en alineación con dicho electrodo y la abertura del matriz presenta un conducto de descarga del material fundente.
