Abstract

UN APARATO PARA LA CONTINUA EXTRUSION DE METALES EN EL CUAL LA ALIMENTACION SE INTRODUCE ENTRE DOS (O MAS) RANURAS REDONDAS SEPARADAS 4 EN UNA RUEDA GIRATORIA 2 (O RUEDAS GIRATORIAS) PARA HACER CONTACTO CON UNA PARTE DE ZAPATA ARQUEADA 8 Y SOPORTES QUE SE EXTIENDEN DENTRO DE LAS RANURAS. LOS SOPORTES OBLIGAN AL ALIMENTO A FLUIR A TRAVES DE LAS ABERTURAS DE SALIDA FRUSTO-CONICAS 10 EN LA PARTE DE LA ZAPATA 8 HACIA UNA CAMARA 6 Y ES EXTRUIDO COMO UN PRODUCTO DE PAREDES RELATIVAMENTE DELGADAS Y UNA GRAN SECCION TRANSVERSAL. LAS ABERTURAS DE SALIDA 10 TIENEN ANGULOS DE CONO ENTRE 5 Y 45 GRADOS. LAS PLACAS DEL MEZCLADOR 14 SE PERFILAN PARA DISTRIBUIR EL FLUJO DE FORMA UNIFORME DESDE LAS ABERTURAS 10 HASTA ALREDEDOR DE LA ABERTURA DE LA MATRIZ 30. UN CUERPO DE MATRIZ DE EXTRUSION PARA EXTRUSIONES CILINDRICAS SE UBICA Y CENTRA AXIALMENTE MEDIANTE TORNILLOS DE ESTABLECIMIENTO 122. CUANDO SE UTILIZA UN NUMERO PAR DE RANURAS 4, SE PUEDE ASEGURAR UN MANDRIL DE EXTRUSION 12 A LA PARTE DE LA ZAPATA 8 MEDIANTE UN PERNO 22 UBICADO EN EL CENTRO DE LAS RANURAS. SE PUEDE INYECTAR LUBRICANTES O LIQUIDOS INHIBIDORES DE OXIDACION EN EL PRODUCTO QUE SE HA EXTRUIDO MEDIANTE UN PASAJE 36,38 QUE ATRAVIESA LA PARTE DE ZAPATA Y EL PERNO 22. EN OTRA REALIZACION, LA CAMARA 6 TIENE TAMBIEN FORMA FRUSTO-CONICA DIVERGENTE CON UN ANGULO DE CONO QUE CORRESPONDE A LAS ABERTURAS 10, POSIBILITANDO LA EXTRUSION DE PRODUCTOS CON UNA MAYOR SECCION TRANSVERSAL. LA FORMA FRUSTO-CONICA PUEDE SER DE UNA SECCION TRANSVERSAL ELIPTICA PARA ALCANZAR UNA DIVERGENCIA NECESARIA O PARA CONCORDAR CON LA CONFIGURACION DEL ORIFICIO DE LA MATRIZ. AL TENER RANURAS SEPARADAS 4 Y ABERTURAS QUE DIVERGEN FRUSTOCONICAMENTE ES POSIBLE LA EXTRUSION DE PRODUCTOS CUYA SECCION TRANSVERSAL ES RELATIVAMENTE GRANDE YA QUE SE INCREMENTA LA TASA DE ALIMENTO DE VOLUMEN Y SE REDUCE LA DISTANCIA POR LA QUE SE TRASLADA EL MATERIAL DESDE LAS RANURAS 4 HASTA EL ORIFICIO DE LA MATRIZ 30, REDUCIENDO LAS PERDIDAS DE FRICCION Y LAS POSIBLES DISCONTINUIDADES DURANTE LA EXTRUSION.
