Abstract

UN APARATO DE EXTRUSION, PARA VARIAR EL PERFIL EXTERNO DE UN EXTRUIDO GENERALMENTE TUBULAR, FORMADO AL UNIR CORRIENTES INTERNAS Y EXTERNAS DE MATERIAL ELASTOMERICO, AL VARIAR EL TAMAÑO DE LA ABERTURA ANULAR EXTERIOR DEL TROQUEL DE EXTRUSION, POR UN ANILLO DE TROQUEL AXIALMENTE MOVIBLE, QUE VARIA EL FLUJO DE LA CORRIENTE EXTERNA DE MATERIAL ELASTOMERICO, QUE SE DEPOSITA EN LA SUPERFICIE EXTERIOR DEL EXTRUIDO TUBULAR. EL ANILLO DE TROQUEL SE FORMA EN EL EXTREMO DE UN PISTON MOVIBLE HIDRAULICAMENTE, Y SE MUEVE DESLIZANTEMENTE Y AXIALMENTE A LO LARGO, Y ESTA LOCALIZADO CONCENTRICAMENTE ALREDEDOR DEL EXTRUIDO TUBULAR. UNA PRIMERA SUPERFICIE AHUSADA ANULAR, DEL ANILLO DE TROQUEL, SE MUEVE A LO LARGO DE UNA SUPERFICIE AHUSADA SIMILAR DE UN PERNIO FIJO DE FORMA CONICA, PARA VARIAR EL TAMAÑO DEL ORIFICIO DE EXTRUSION EXTERIOR FORMADO ENTRE ELLOS. UNA SEGUNDA SUPERFICIE, AHUSADA OPUESTAMENTE A LA DE LA PRIMERA SUPERFICIE AHUSADA DEL ANILLO DE TROQUEL, Y FORMADA ALLI INTEGRALMENTE COMO MIEMBRO DE UNASOLA PIEZA, COMUNICA CON EL CANAL DE FLUJO DE LA CORRIENTE DEL MATERIAL ELASTOMERICO EXTERIOR Y COMPENSA UN CAMBIO EN LA PRESION DENTRO DE LA CORRIENTE DE FLUJO EXTERIOR, CAUSADO AL VARIAR EL VOLUMEN DE FLUJO DE LA CORRIENTE EXTERIOR, EN UN LUGAR GENERALMENTE ADYACENTE A LA APLICACION DE LA CORRIENTE EXTERIOR EN LA SUPERFICIE EXTERIOR DEL EXTRUIDO TUBULAR. UNA GUIA DE REFUERZO, DIRIGE UNA PLURALIDAD DE ELEMENTOS DE REFUERZO TIPO FIBRA AL EXTRUIDO TUBULAR, GENERALMENTE EN LA UNION DE LAS CORRIENTES EXTERNA E INTERNA DEL MATERIAL ELASTOMERICO. SE PRESENTA TAMBIEN UN METODO PARA VARIAR EL PERFIL EXTERIOR DEL EXTRUIDO TUBULAR.
