Abstract

LA INVENCION SE REFIERE A UN CABEZAL PORTAPIEZAS (66) PARA LA FORMACION DE ENSANCHES PERMANENTES EN LAS PORCIONES FINALES (50) DE TUBOS DE PLASTICO (51), QUE CONSTA DE: UNA MATRIZ (52) QUE INCLUYE UNA CAVIDAD (80) PARA RECIBIR UNA PORCION FINAL TERMICAMENTE PLASTIFICADA (50) DE UN TUBO (51), QUE TIENE UNOS CONDUCTOS DE FLUJO (54) PARA UN FLUIDO A PRESION; UN MANDRIL DE CONFORMACION (55), QUE SE PUEDE INSERTAR EN LA PORCION FINAL (50) DEL TUBO (52) Y SE ENCUENTRA COLOCADO CENTRALMENTE RESPECTO A LA MATRIZ (52) E INCLUYE ADEMAS UNOS TUBOS DE FLUJO (58) PARA UN FLUIDO A PRESION; UN REBORDE (60) MONTADO COAXIALMENTE Y DE FORMA DESLIZANTE RESPECTO AL MANDRIL (55) Y A LA MATRIZ (52), Y QUE TIENE UNA SUPERFICIE DE PERCUSION (82) QUE SE PUEDE ASOCIAR A UN BORDE (62) DE LA PORCION FINAL (50) DEL TUBO (51); UNOS ELEMENTOS DE CIERRE (59) COLOCADOS SOBRE LA MATRIZ (52) Y EL MANDRIL (55), DESTINADOS A INTERACTUAR CON UNA SUPERFICIE EXTERNA (84) Y UNA SUPERFICIE INTERNA (83) DE LA PORCION FINAL (51) DELTUBO (50). LA MATRIZ (52), EL MANDRIL (55) Y EL REBORDE (60) DEFINEN JUNTOS PERIFERICAMENTE UNA CAMARA DE CONFORMACION (72) DE LA PORCION FINAL (50) DEL TUBO (51), EN DONDE DICHA CAMARA DE CONFORMACION (72) QUEDA SUBDIVIDIDA POR EL TUBO (51) EN UNA PRIMERA Y UNA SEGUNDA CAMARAS DE PRESION (63,64) DE UN FLUID; LA PRIMERA CAMARA DE PRESION QUEDA COLOCADA ENTRE LA SUPERFICIE LATERAL DEL MANDRIL (55) Y LA SUPERFICIE INTERNA (83) DEL TUBO (51); LA SEGUNDA CAMARA ((64) QUEDA COLOCADA ENTRE LA SUPERFICIE EXTERNA (84) DEL TUBO (51) Y LA SUPERFICIE INTERNA (53) DE LA MATRIZ (52); LAS CAMARAS DE PRESION (63,64) SON ALIMENTADAS POR LOS CONDUCTOS (54,58) DE MODO QUE DILATEN Y CONTRAIGAN CIRCUNFERENCIAL Y SUCESIVAMENTE LA PORCION FINAL (50) DEL TUBO (51) PARA PROVOCAR LA DEFORMACION PERMANENTE DEL TUBO (51).
