Abstract

LA INVENCION SE REFIERE A UN ACCIONAMIENTO PARA UNA PRENSA, EN PARTICULAR DE UNA PRENSA DE PERFILADO DE CHAPAS, DISPONIENDO EL ACCIONAMIENTO DE UNA COMPUERTA (11) ALTERNATIVA SITUADA VERTICALMENTE Y UN TACO (17) DE PRESION DESPLAZADO HIDRAULICAMENTE. EL TACO DE PRESION ES MOVIDO MEDIANTE AL MENOS UN CILINDRO (21,101) HIDRAULICO DE UNA PRIMERA MAQUINA (30) HIDROSTATICA PARA EJECUTAR UNA CARRERA HACIA LA COMPUERTA, Y PARA EJECUTAR MEDIANTE LA COMPUERTA LA CARRERA DE RETORNO. EL BALANCE DE ENERGIA EN LA UNIDAD DE ACCIONAMIENTO DE UNA PRENSA DE ESTE TIPO ES MEJORADO EN VIRTUD DEL HECHO DE QUE LA PRIMERA MAQUINA HIDROSTATICA ESTA DISEÑADA, EN PARTICULAR, COMO UNA MAQUINA DE PISTON AXIAL, Y PARTICULARMENTE COMO UNA MAQUINA QUE PUDE GIRAR EN AMBAS DIRECCIONES Y ESTA EQUIPADA CON UN CONTROL DE PRESION, Y EN VIRTUD DEL HECHO DE QUE, DURANTE AL MENOS PARTE DE LA CARRERA DE RETORNO DEL TACO DE PRESION, EL FLUIDO HIDRAULICO FLUYE FUERA DEL CILINDRO HIDRAULICO A TRAVES DE UNA SEGUNDA MAQUINA (30,51,70)HIDROSTATICA.
