Abstract
PROCEDIMIENTO PARA LA FABRICACION DE TUBERIA CIRCULAR EN MATERIAL TERMOPLASTICO (P.V.C). CONSISTE EN REALIZAR SECUENCIALMENTE LAS SIGUIENTES OPERACIONES: INTRODUCIR EL TUBO DE MATERIAL EN BRUTO (28) EN EL MOLDE (12), DE FORMA QUE SU LONGITUD SEA SUPERIOR A LA DE ESTE; BAJAR EL MOLDE A LA ALTURA DE LOS TOPES (15,17) DE FORMA QUE EL TUBO (28) QUEDE CENTRADO; ACERCAR LOS TOPES PARA QUE EL TUBO ENTRE EN LOS MANDRILES (19,20); BAJAR EL MOLDE A LA POSICION DE TRABAJO CENTRADO CON LOS TOPES Y CERRAR ESTOS; INTRODUCIR AGUA CALIENTE (90 GC) A PRESION POR CONDUCTOS NO DESCRITOS EN EL INTERIOR DEL TUBO PARA QUE SE EXPANDA HASTA EL DIAMETRO DEL MOLDE; ENFRIAR CON INYECCION DE AGUA FRIA; RETIRAR LOS TOPES, QUITANDO PRIMERO EL TOPE CON MANGUITO (15) Y HACIENDO BASCULAR EL MOLDE HACIA EL LADO DEL OTRO TOPE (17) PARA ELIMINAR LOS RESTOS DE AGUA ANTES DE SOLTAR EL TOPE (17); CORTAR LOS EXTREMOS NO EXPANDIDOS Y EXTRAER EL TUBO.
