Abstract

Método de formar un trozo de tubo con una aleta helicoidal integral que comprende desplazar material de la superficie exterior de una pieza bruta tubular en una dirección generalmente radial hacia fuera dirigiendo presión en una dirección radialmente hacia dentro sobre porciones periféricas axilmente espaciadas helicoidalmente alineadas de la pieza y dirigir el material desplazado en una trayectoria helicoidal determinada de antemano en borne del eje de la pieza sin someter el material a desviación lateral o a compresión axil.Method of forming a length of tube with an integral helical fin comprising displacing material from the outer surface of a tubular blank in a generally radially outward direction by directing pressure in a radially inward direction on helically aligned axially spaced peripheral portions of the part and directing the displaced material in a helical trajectory determined in advance in the terminal of the axis of the piece without subjecting the material to lateral deflection or axial compression.
