Abstract

PROCEDIMIENTO DE ESTIRADO DE TUBOS. LOS TUBOS (4) QUE VAN A SER ESTIRADOS SE ENCUENTRAN SOBRE UNOS APOYOS (32). SE ENCHUFAN CON LA BARRA INFERIOR DE MANDRIL (9) Y SE DESPLAZAN EN LA DIRECCION (Z''). EXISTE UN APOYO DE BARRA (20), DESPLAZABLE LONGITUDINALMENTE, QUE PERMITE LA FIJACION LOCAL DE CADA BARRA DE MANDRIL (9) EN UN SECTOR DE BARRA (21) CENTRAL Y QUE LIMITA EL MOVIMIENTO DE AVANCE DEL TUBO EN LA DIRECCION (Z''). A CONTINUACION SE HACE ROTAR TODA LA JAULA ALREDEDOR DE SU EJE (14) MEDIANTE UN MOTOR (17) Y CORONA (15), HASTA QUE EL TUBO SE ENCUENTRA FRENTE A LA MATRIZ DE ESTIRADO (3). LA TENAZA DE ESTIRADO APREHENDE EL TUBO EN LA ZONA DE SU GANCHO DE ESTIRADO, REALIZANDO LA TRACCION LOS MOTORES (7) A TRAVES DE CADENAS (8). CUANDO EL CARRO DE ESTIRADO LLEGA AL FINAL DE SU CAMINO LA TENAZA (6) SE ABRE Y DEJA CAER EL TUBO ESTIRADO. SE OFRECE UNA ALTERNATIVA CON TRES MATRICES DE ESTIRADO Y SEIS BARRAS DE MANDRIL.
