Abstract

LA INVENCION SE RELACIONA CON LA CONFIGURACION DE UNA PRENSA PARA CONFORMACION DE CHAPAS METALICAS, A FIN DE CORTAR O RALENTIZAR EL FLUJO DE LIQUIDO EN EL SISTEMA HIDRAULICO EN UN MOMENTO ARBITRARIAMENTE ESCOGIDO, EN COORDINACION CON LOS MOVIMIENTOS DE APERTURA Y CIERRE DE LA MENCIONADA HERRAMIENTA. CUANDO SE CIERRA LA HERRAMIENTA, UNA VALVULA ANTIRRETORNO (6) PERMITE EL FLUJO EN UNA DETERMINADA DIRECCION DESDE UNA UNIDAD HIDRAULICA CILINDRO/PISTON PRIMARIA (7), QUE SE ENCUENTRA POR TANTO EN FASE DE COMPRESION, A UN ACUMULADOR (8). UNA PRIMERA VALVULA (9) PERMITE DE FORMA SELECTIVA EL FLUJO ENTRE EL ACUMULADOR (8) Y UNA UNIDAD HIDRAULICA CILINDRO/PISTON SECUNDARIA (10) QUE, CUANDO SE PRODUCE DICHO FLUJO, CAMBIA DE LA POSICION BASICA DE COMPRESION A OTRA DE EXPANSION. EN PARALELO CON LA VALVULA ANTIRRETORNO (6) EXISTE UNA SEGUNDA VALVULA (11) QUE, CUANDO LA UNIDAD HIDRAULICA CILINDRO/PISTON PRIMARIA (7) HAYA QUEDADO LIBERADA POR LA APERTURA DE LA HERRAMIENTA, PERMITIRA DE FORMA SELECTIVA ELFLUJO DE RETORNO A LA CITADA UNIDAD PRIMARIA (7) DESDE EL ACUMULADOR (8), O, SI SE ABRE TAMBIEN LA PRIMERA VALVULA (9), DESDE LA UNIDAD HIDRAULICA CILINDRO/PISTON SECUNDARIA (10), QUE ESTA DISEÑADA PARA RETORNAR ENTONCES A LA POSICION BASICA DE COMPRESION.
