Abstract

PERFECCIONAMIENTOS EN LOS CILINDROS PARA PRENSAS DE EXTRUSION DE ALUMINIO. SE APLICAN A PRENSAS QUE COMPRENDEN CILINDROS MULTIPLES CON PISTONES DE ACCIONAMIENTO FLUODINAMICO CONJUNTO PARA LA IMPULSION DEL ALUMINIO AL INTERIOR DE LA MATRIZ; LOS PERFECCIONAMIENTOS SE CARACTERIZAN POR EL HECHO DE QUE LOS CILINDROS MULTIPLES COMPRENDEN POR LO MENOS DOS CAMARAS O CILINDROS PROPIAMENTE DICHOS (2,3) COAXIALES PARA LOS PISTONES (6,7) CORRESPONDIENTES, LOS CUALES QUEDAN MONTADOS EN TANDEM SOBRE UN EJE COMUN (5) QUE ATRAVIESA A AMBAS CAMARAS (2,3) Y QUE SE UNE, POR SU EXTREMO SALIENTE (8), AL IMPULSOR PROPIAMENTE DICHO DEL ALUMINIO EN EL INTERIOR DEL MOLDE. PROPORCIONAN UN SISTEMA MULTIPLICADOR DE PRESION DE SENCILLA REALIZACION, ESCASO VOLUMEN Y GRAN RENDIMIENTO.
