Abstract

SISTEMA EYECTOR MECANICO-HIDRAULICO PARA PRENSAS. UN PISTON (38) SITUADOEN EL INTERIOR DE UNA CAMARA (36), A FORMA DE CILINDRO, ES ACCIONADO POR UN FLUIDO HIDRAULICO, ORIGINANDO EL DESPLAZAMIENTO VERTICAL DEL MISMO. DICHO PISTON (38), EN SU DESPLAZAMIENTO ASCENDENTE, ACTUA SOBRE UN MIEMBRO EYECTOR (50), EL CUAL A SU VEZ LO HACE SOBRE LA PIEZA DE TRABAJO (W), SIENDO EXPULSADA ESTA DE LA MATRIZ (34) DE LA PRENSA (10).
