Abstract

SISTEMA DE PREACELERACION PARA UN COJIN HIDRAULICO DE PRENSA. UN PAR DE CILINDROS (14) DE PRESION SOPORTAN EL PESO DEL COJIN ADEMAS DEL PISADOR (20) Y DE LA CHAPA (21), UTILIZANDOSE ESTA FUERZA COMO FUENTE PRINCIPAL DE ENERGIA. LA CADENA CINEMATICA (2, 3, 4, 5, 6, 7, 8, 13, 14, 17) QUE TRANSMITE LA VELOCIDAD DEL CARRO (1) MOVIL AL COJIN, Y DE ESTE AL PISADOR, SE CONFIGURA TOTALMENTE CON ELEMENTOS MECANICOS: LA LEVA (4) TRANSMISORA DEL MOVIMIENTO ES DEL TIPO RECTILINEO DE PERFILES CONJUGADOS, Y MUEVE HORIZONTALMENTE EN UNO U OTRO SENTIDO EL VASTAGO (7) Y LOS PISTONES (8) EN SERIE DE UN PAR DE VALVULAS (6) MECANICAS DE CORREDERA O VALVULAS DE PREACELERACION, LOS CUALES ADMITEN EL FLUIDO DE LOS CILINDROS (13) CONTROLANDO ASI LA ACELERACION DE LOS VASTAGOS (14) Y DE LA PLACA DE PRESION (17). LA CARRERA DEL PISTON (12) DE DICHOS CILINDROS DETERMINA EL MOVIMIENTO DEL COJIN, A LA VELOCIDAD DE FLUJO DEL ACEITE INTERCAMBIADO.
