Abstract

PROCEDIMIENTO DE ESTIRADO DE TUBOS. ANTES DEL ESTIRADO DEL TUBO SE REALIZA UN EMBUTIDO EN LA PARTE DELANTERA DEL MISMO. EL TOCHO, ORIGINALMENTE TUBULAR (21), SE ESTRECHA DE FORMA CONICA CON UN ANGULO (A) DE 22 A 28 C. LA LINEA DE TRAZOS DISCONTINUOS (22) INDICA LA BARRA (2) DEL BANCO DE ESTIRADO A INTRODUCIR EN EL TOCHO TUBULAR. LA DIFERENCIA ENTRE LOS DIAMETROS (DR, DS) DEBE SER DE UN 4 A UN 6 POR 100 DEL DIAMETRO (DS). SE PROCEDE DESPUES AL ESTIRADO MEDIANTE EL PASO DEL TUBO EMBUTIDO POR UNA SERIE DE CALIBRES.
