Abstract

EL INVENTO SE REFIERE A UN DISPOSITIVO HIDRAULICO DE TRACCION EN LA MESA DE PRENSADO DE UNA PRENSA SIMPLE O DOBLE. LA MAZA DE TRACCION (7) SE ACTIVA MECANICAMENTE Y EL DISPOSITIVO DE TRACCION ES ADECUADO PARA DOS TIPOS DE TRABAJO QUE SE SELECCIONAN AL CAMBIAR LA HERRAMIENTA. ESO SON, FUNCIONAMIENTO CON LA HERRAMIENTA (3) EN EL CENTOR DE LA INSTALACION DE TRACCION, O CON DOS HERRAMIENTAS PARALELAS. AL BAJAR LA MAZA, SE PUEDE AJUSTAR LA FUERZA DE SOPORTE DE CHAPA, EN LAS CUATRO ESQUINAS. LA TAREA DEL INVENTO ES, SIMPLIFICAR EL CAMBIO DE TIPO DE TRABAJO. EN LOS DOS TIPOS DE TRABAJO, LA CONTRAFUERZA, PRODUCIDA AL BAJAR LA MAZA, SE REALIZA, MEDIANTE COJINES FELXIBLES, EN LAS CUATRO ESQUINAS DE LAS MORDAZAS DE PRENSADO (9). LA ADAPTACION A LOS DIFERENTES TIPOS DE TRABAJO SE EFECTUA AÑADIENDO O QUITANDO LOS DIFERENTES CILINDROS DE PRESION.THE INVENTION REFERS TO A HYDRAULIC TRACTION DEVICE ON THE PRESSING TABLE OF A SINGLE OR DOUBLE PRESS. THE TRACTION HAMMER (7) IS MECHANICALLY ACTIVATED AND THE TRACTION DEVICE IS SUITABLE FOR TWO TYPES OF WORK THAT ARE SELECTED BY CHANGING THE TOOL. THAT IS, OPERATION WITH THE TOOL (3) IN THE CENTER OF THE TRACTION FACILITY, OR WITH TWO PARALLEL TOOLS. WHEN LOWERING THE HUB, YOU CAN ADJUST THE SHEET SUPPORT STRENGTH AT THE FOUR CORNERS. THE TASK OF THE INVENTION IS, TO SIMPLIFY THE CHANGE OF JOB TYPE. IN THE TWO TYPES OF WORK, THE COUNTER-FORCE, PRODUCED BY LOWERING THE MALL, IS MADE, THROUGH FELXIBLE CUSHIONS, AT THE FOUR CORNERS OF THE PRESSING JAWS (9). ADAPTATION TO DIFFERENT TYPES OF WORK IS MADE BY ADDING OR REMOVING THE DIFFERENT PRESSURE CYLINDERS.
