Abstract

APARATO PARA FABRICAR TUBERIAS CILINDRICAS DE MATERIAL TERMOPLASTICO (P.V.C.). CONSTA DE UN MOLDE DE SECCION CILINDRICA (12) CON UNA LIGERA CONICIDAD; DE DOS COLUMNAS DE FIJACION (10,11) SOBRE LAS QUE SE DESLIZA EL MOLDE AL ACCIONAR LOS CILINDROS HIDRAULICOS (21,22), Y DE DOS TOPES (15,17) CON CILINDROS HIDRAULICOS (13,14) PARA CERRAR EL MOLDE Y QUE SE DESLIZA POR LOS CARRILES (16,18). LA TUBERIA EN BRUTO (28) ES DE MAYOR LONGITUD QUE EL MOLDE. SU FIJACION SE HACE CON DISPOSITIVO DE SUJECION Y CON LOS MANDRILES (19,20), DE DIAMETRO IGUAL AL INTERIOR DEL TUBO. EL TOPE (15) TIENE, INTERIORMENTE, FORMA DE MANGUITO PARA QUE LA TUBERIA TERMINE ASI EN UN EXTREMO. LA EXPANSION SE HACE CON AGUA CALIENTE INYECTADA. U
