Abstract

DISPOSITIVO DE EXTRUSION PARA REALIZAR UNA PIEZA PERFILADA DE SECCION COMPLEJA, QUE COMPRENDE UNA PARTE INTERNA Y UNA CAPA EXTERNA. EL DISPOSITIVO COMPRENDE UN PRIMER CANAL DE ENTRADA (12) PARA UNA PRIMERA MATERIA PLASTICA DERRETIDA (11), UN CUERPO (10) QUE COMPRENDE UNA CANAL DE EXTRUSION (22) CUYA PARED DEFINE EL CONTORNO EXTERNO DE LA PIEZA PERFILADA, Y UN NUCLEO AXIAL DE EXTRUSION (24) QUE SIRVE PARA DEFINIR EL CONTORNO INTERNO DE LA PIEZA PERFILADA. ESTE DISPOSITIVO LLEVA TAMBIEN UN SEGUNDO CANAL DE ENTRADA (14) PARA UNA SEGUNDA MATERIA PLASTICA DERRETIDA (13), Y MEDIOS PARA REGULAR EL FLUJO DE LA SEGUNDA MATERIA PLASTICA DERRETIDA (13) EN EL SEGUNDO CANAL DE ENTRADA (14) PARA DETERMINAR, EN EL EXTREMO DE SALIDA (30) DE ESTE ULTIMO, UNA DISTRIBUCION HOMOGENEA DE LA SEGUNDA MATERIA PLASTICA EN EL CONTORNO EXTERNO DE LA PIEZA PERFILADA.
