Abstract

LA PRENSA HIDRAULICA-NEUMATICA COMBINADA (1) CON GOLPE CONTROLADO, INCLUYE UN CUERPO (2) DENTRO DEL CUAL SE DEFINE UNA CAMARA PRINCIPAL CILINDRICA (3); ESTA CAMARA SE ACOMODA, DE FORMA QUE PUEDA DESLIZARSE A LO LARGO DE UNA DIRECCION AXIAL, UN PISTON DE TRABAJO (4) QUE SOBRESALE DEL CUERPO CON SU VASTAGO (5). EL PISTON DE TRABAJO (4) DELIMITA, EN LA CAMARA PRINCIPAL, UN PRIMER COMPARTIMENTO (6) QUE CONTIENE UN LIQUIDO Y ESTA CONECTADO A TRAVES DE UN PASAJE (7), A OTRA CAMARA SECUNDARIA (SIGMA) PROVISTA DE ELEMENTOS (10) PARA EJERCER PRESION SOBRE EL LIQUIDO CONTENIDO EN LA CAMARA SECUNDARIA A FIN DE TRANSFERIR POR LO MENOS PARTE DE DICHO LIQUIDO DESDE LA CAMARA SECUNDARIA AL PRIMER COMPARTIMENTO A FIN DE MOVER AXIALMENTE EL PISTON DE TRABAJO. SE PROPORCIONAN ELEMENTOS DE CORTE (13) EN EL PASAJE (;) QUE PODRAN ACTIVARSE POR CONTROL A FIN DE AISLAR HIDRAULICAMENTE EL PRIMER COMPARTIMENTO (6) DE LA CAMARA SECUNDARIA (8), Y EXISTE UN PISTON DE ACTUACION (12) PROVISTO DE UN VASTAGO (13) QUE PUEDE INSERTARSE DE MANERA ESTANCA EN EL PRIMER COMPARTIMENTO (6) A FIN DE AUMENTAR LA PRESION HIDRAULICA DENTRO DEL PRIMER COMPARTIMENTO, AUMENTANDO LA FUERZA DE ACTUACION QUE ACTUA SOBRE EL PISTON DE TRABAJO (4) PARALELO A SU EJE. LA PRENSA COMPRENDE ADEMAS, ELEMENTOS (21, 24) PARA LA DELIMITACION DEL GOLPE SOBRE EL PISTON DE TRABAJO
