Abstract

Se describe un aparato (100) para engrosar un tubo (101) en su borde (201). El aparato (100) incluye un primer miembro de soporte (102), que está configurado para soportar rígidamente una primera superficie longitudinal (110) del tubo (101) a lo largo de su longitud excluyendo cualquiera de los extremos del tubo (101). Un segundo miembro de soporte (103) configurado para soportar rígidamente una segunda superficie longitudinal (111) del tubo (101) a lo largo de su longitud excluyendo los extremos del tubo (101). Un punzón (104) accionado por una fuente de energía externa, en el que el punzón (104) está configurado para ejercer fuerza en cualquiera de los extremos del tubo (101). La aplicación de fuerza por el punzón (104) deforma plásticamente los extremos del tubo (101), engrosando así el tubo (101) en uno o ambos extremos. El aparato de la presente divulgación es de construcción simple y mejora el proceso de engrosamiento del tubo en su borde.An apparatus (100) is described for thickening a tube (101) at its edge (201). The apparatus (100) includes a first support member (102), which is configured to rigidly support a first longitudinal surface (110) of the tube (101) along its length excluding either end of the tube (101). A second support member (103) configured to rigidly support a second longitudinal surface (111) of the tube (101) along its length excluding the ends of the tube (101). A punch (104) actuated by an external power source, wherein the punch (104) is configured to exert force on either end of the tube (101). The application of force by the punch (104) plastically deforms the ends of the tube (101), thus thickening the tube (101) at one or both ends. The apparatus of the present disclosure is simple in construction and improves the thickening process of the tube at its edge.
