摘要

A process for manufacturing hollow metal profiles, from a section of prefabricated tube, essentially characterized in that once made a forgeable welding or simply joined for the subsequent welding, a suitable matrix is housed inside said tube, according to the profile desired and in all its length, passing the entire tubular section with the male housed, between four laminating rollers simultaneously, the placement of said rolls, by respective parts, in vertical and horizontal position, convergent with the shape recorded in all its development, being variable the dimensions of the rollers and their different diameters, according to the different profiles to obtain, that comes out of block, matrix and tube machine, proceeding to the extraction of the indicated matrix, to leave the hollow profile by means of platelet descamisadora that consists of introducing a plate of suitable thickness, with the silhouette of the pe rfil in the same, purpose foreseen so that once it reaches an expected stop, with the force applied by itself to the descamisado of the matrix cleanly and in continuous work.
