Abstract

EL ESTIRAMIENTO DE CUERPOS DE ALUMINIO ESTIRADOS O EXTRUIDOS HUECOS SE LLEVA A CABO FORZANDO EL CUERPO HUECO A TRAVES DE UN ANILLO DE ESTIRAMIENTO EMPUJADO POR UN EMBOLO BUZO O UN MANDRIL COLOCADOS DENTRO DE DICHO CUERPO Y CALENTADO A UNA TEMPERATURA NO INFERIOR A 90 C Y GENERALMENTE ENTRE 105 C Y 140 C. EL EQUIPAMIENTO PARA LA APLICACION DEL PROCESO COMPRENDE UNA O MAS BARRAS DE ALIMENTACION DE PORTAHERRAMIENTAS EN EL QUE LOS EMBOLOS BUZOS O LOS MANDRILES Y UNO O MAS ANILLOS DE ESTILLAMIENTO SE INSERTAN O ACOPLAN ALTERNATIVAMENTE Y EN EL QUE CADA EMBOLO BUZO TIENE UNA CAMARA INTERNA (22), MEDIOS DE CALENTAMIENTO (14) DISPUESTOS EN DICHA CAMARA Y MUESCAS LONGITUDINALES (16) A LO LARGO DE SU SUPERFICIE EXTERIOR.THE STRETCH OF STRETCHED ALUMINUM BODIES OR EXTRUDED HOLES IS CARRIED OUT BY FORCING THE HOLLOW BODY THROUGH A STRETCH RING PUSHED BY A DUCK PITCH OR A GENERAL CHAIN PLACED INSIDE OF A SINGLE BODY AND HEATED A NEAR A HEATED NEAR TO ONE 105 CY 140 C. THE EQUIPMENT FOR THE APPLICATION OF THE PROCESS INCLUDES ONE OR MORE BARRIER FEEDING BARS IN WHICH THE DIVING PITS OR CHUCKS AND ONE OR MORE STYLE RINGS ARE INSERTED OR COUPLED ALTERNATIVELY AND IN WHICH EACH POCKET IS DIVIDED AN INTERNAL CHAMBER (22), HEATING MEANS (14) ARRANGED IN SUCH CHAMBER AND LONGITUDINAL NOTES (16) ALONG ITS OUTER SURFACE.
