Abstract

SE DESCRIBE UNA PRENSA HIDRAULICA O MECANICA CON UNA INSTALACION TREFILADORA O UN ESCALON DE TREFILACION PARA UNA PRENSA ESCALONADA, EN EL QUE LA SUJECION DE LA CHAPA MEDIANTE UNA CONTRASUJETADOR DE CHAPA SE EFECTUA MEDIANTE UN MEDIO HIDRAULICO. A FIN DE AMORTIGUAR EL CHOQUE Y EL RUIDO DEL CHOQUE QUE SE PRODUCEN AL DAR LA HERRAMIENTA SUPERIOR (7) CONTRA EL CONTRASUJETADOR DE CHAPA (6), Y DE REALIZAR LA TREFILACION MEDIANTE UN MANDO FORZADO, EL MOVIMIENTO DEL PORTAHERRAMIENTA DE EMBUTICION (8) SE TRANSMITE A UN CILINDRO DE BOMBEO (12) CUYO MEDIO HIDRAULICO ACTUA SOBRE OTRO CILINDRO DE PRESION (17) QUE VA UNIDO AL COJIN DE TREFILACION (10) DE TAL MANERA, QUE SE PRODUCE UNA PREACELERACION. LA SUJECION DEL COJIN (10) SE EFECTUA, ACABADA LA PREACELERACION, MEDIANTE UN ACUMULADOR DE PRESION (21).A HYDRAULIC OR MECHANICAL PRESS IS DESCRIBED WITH A WINDING INSTALLATION OR A WINDING STAGE FOR A STAGED PRESS, IN WHICH THE SHEET IS SUPPORTED BY A SHEET COUNTERHEADER BY A HYDRAULIC MEDIA. IN ORDER TO REDUCE THE SHOCK AND SHOCK NOISE THAT PRODUCE WHEN GIVING THE UPPER TOOL (7) AGAINST THE SHEET COUNTERHOLSTER (6), AND TO PERFORM THE TREFILATION THROUGH A FORCED CONTROL, THE MOVEMENT OF THE EMBUTITION TOOL HOLDER (8) IT IS TRANSMITTED TO A PUMPING CYLINDER (12) WHOSE HYDRAULIC MEDIUM OPERATES ON ANOTHER PRESSURE CYLINDER (17) WHICH IS ATTACHED TO THE TREFILATION PAD (10) IN SUCH A WAY THAT PRE-ACCELERATION OCCURS. THE SUPPORT OF THE CUSHION (10) IS CARRIED OUT, WITH THE PRE-ACCELERATION COMPLETED, USING A PRESSURE ACCUMULATOR (21).
