Abstract

2.1. EL PROBLEMA DE LA INVENCION SE ENCUENTRA EN QUE EVENTUALMENTE DURANTE EL PROCESO DE EXTRACCION A PARTIR DE UNA PRENSA DE ACCIONAMIENTO SENCILLO O DE UNA ETAPA DE EXTRACCION DE ACCIONAMIENTO SENCILLO DE UNA PRENSA DE TRANSFERENCIA, DEBE CONSEGUIRSE UNA SUJECION DE LA PIEZA DE TRABAJO CONTRA EL EMPUJADOR Y CON ELLO EL SOPORTE DE CHAPA, SIN QUE EL EMPUJADOR DEBA TRABAJAR CONTRA ESTA FUERZA; ASI COMO SALGA SIN LA UNION ENTRE EL EMPUJADOR DE LA PRENSA Y LA PLACA DE PERNOS DE PRESION, PARA LA REDUCCION DE LA ANCHURA DEL PUNTAL SOPORTE DE LA PRENSA Y AL MISMO TIEMPO LA POSICION DE LA GUIA DEL EMPUJADOR Y SIN INFLUENCIAR LA ZONA LIBRE ENTRE EL PUNTAL SOPORTE LATERAL Y LA MESA DE DESPLAZAMIENTO O EL PUNTAL SOPORTE Y EL CARRIL SOPORTE. 2.2. EN EL SOPORTE DE CHAPA SE DISPONE DEL CILINDRO (14) DE TRABAJO CON BARRAS DE EMBOLO EN AMBAS CARAS EN LA MESA DE LA PRENSA, QUE SE APUNTALAN EN EL PROCESO DE TRACCION UNA CON OTRA. UNA CARA DE LAS BARRAS DEL EMBOLO ESTA UNIDA A TRAVES DE UN ORGANO DE TRANSMISION CON EL MARCO SOPORTE DE CHAPA, EN EL QUE AL MISMO TIEMPO DE FORMA INTERNA SE DISPONE DE UN AGREGADO DE ALMOHADA PARA LA GENERACION DEL MOVIMIENTO HACIA ARRIBA DE LA ALMOHADA DE TRACCION Y DE LA FUERZA DE EXPULSION, CARACTERIZADO PORQUE LA OTRA BARRA (12) DE EMBOLO DEL CILINDRO (14) DE TRABAJO ESTA UNIDA CON UN ENGRANAJE PARA LA TRANSFORMACION DEL MOVIMIENTO ROTATIVO EN MOVIMIENTO DE TRASLACION. EL ENGRANAJE SE ENCUENTRA EN EL LADO DE ENTRADA EN UNION ACTIVA CON EL EJE (27) DE ACCIONAMIENTO DEL ACCIONAMIENTO (1) DE LA PRENSA Y EL EMBOLO (15) DE TRABAJO ES IMPULSABLE A PRESION EN LA CARA DEL ACCIONAMIENTO DEL CILINDRO (14) DE TRABAJO. UNA OTRA SOLUCION ESTA CONFIGURADA SIN AGREGADO DE ALMOHADA Y CON EMBOLOS (15) DE TRABAJO IMPULSADOS A PRESION EN LAS DOS CARAS EN CADA CILINDRO (14) DE TRABAJO.2.1. THE PROBLEM OF THE INVENTION IS THAT EVENTUALLY DURING THE EXTRACTION PROCESS FROM A SIMPLE DRIVE PRESS OR A SIMPLE OPERATION EXTRACTION STAGE OF A TRANSITION PRESSURE SHOULD BE OBTAINED. AND WITH THIS THE SUPPORT OF SHEET, WITHOUT THE PUSHER MUST WORK AGAINST THIS FORCE; AS WELL AS LEAVES WITHOUT THE UNION BETWEEN THE PRESS PUSHER AND THE PRESSURE BOLTS PLATE, FOR THE REDUCTION OF THE WIDTH OF THE PRINT SUPPORT OF THE PRESS AND AT THE SAME TIME THE POSITION OF THE PUSHER'S GUIDE AND WITHOUT INFLUENCING THE FREE ZONE BETWEEN THE SIDE SUPPORT STAND AND THE TRAVEL TABLE OR THE SUPPORT STAND AND THE SUPPORT LANE. 2.2. ON THE SUPPORT OF SHEET A WORKING CYLINDER (14) IS PROVIDED WITH PLUNGER BARS ON BOTH SIDES AT THE PRESS TABLE, WHICH ARE POINED IN THE TRACTION PROCESS ONE WITH ANOTHER. A FACE OF THE BARS OF THE PITCH IS JOINED THROUGH A TRANSMISSION ORGAN WITH THE FRAME SUPPORT OF SHEET, IN WHICH AT THE SAME TIME INTERNALLY, A PILLOW AGGREGATE IS PROVIDED FOR THE MOVEMENT UPWARD THE PILLOW OF TRACTION AND FORCE OF EXPULSION, CHARACTERIZED BECAUSE THE OTHER BAR (12) OF THE CYLINDER OF THE WORK (14) IS UNITED WITH A GEAR FOR THE TRANSFORMATION OF THE ROTARY MOVEMENT IN MOVEMENT OF TRANSLATION. THE GEAR IS ON THE ENTRY SIDE IN AN ACTIVE UNION WITH THE PRESS DRIVE AXLE (27) OF THE PRESS AND THE WORKING PIT (15) IS PRESSURE PRESSURE ON THE CYLINDER ACTUATION FACE (14) OF WORK. ANOTHER SOLUTION IS CONFIGURED WITHOUT PILLOW ADDING AND WITH WORK PITS (15) PRESSURED ON THE TWO SIDES IN EACH WORKING CYLINDER (14).
