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 PIEZA DE TRABAJO (6) SE SUJETA MEDIANTE UN CONTRASUJETADOR DE CHAPA (7). A FIN DE AMORTIGUAR EL CHOQUE Y EL RUIDO DEL CHOQUE QUE SE PRODUCEN AL DAR LA HERRAMIENTA SUPERIOR (8) CONTRA EL CONTRASUJETADOR DE CHAPA (7), EL MOVIMIENTO DEL PORTAHERRAMIENTA DE EMBUTICION (9) SE TRANSMITE A UNO O MAS CILINDROS HIDRAULICOS (33) CUYO MEDIO HIDRAULICO ACTUA POR REGULACION Y POR MANDO FORZADO SOBRE OTRO CILINDRO AMORTIGUADOR (13) QUE, A SU VEZ, VA UNIDO AL COJIN DE TREFILACION Y, A TRAVES DE ESTE, AL CONTRASUJETADOR DE CHAPA (7).A HYDRAULIC OR MECHANICAL PRESS IS DESCRIBED WITH A WINDING INSTALLATION OR A WINDING STAGE FOR A STAGED PRESS, IN WHICH THE WORKPIECE (6) IS SECURED THROUGH A SHEET METAL COUNTER (7). IN ORDER TO DAMPER THE SHOCK AND SHOCK NOISE THAT PRODUCE WHEN THE UPPER TOOL IS GIVEN (8) AGAINST THE SHEET COUNTERHOPPER (7), THE MOVEMENT OF THE EMBUTTING TOOL HOLDER (9) IS TRANSMITTED TO ONE OR MORE HYDRAULIC CYLINDERS (33) ) WHOSE HYDRAULIC MEDIUM ACTUATES BY REGULATION AND BY FORCED CONTROL OVER ANOTHER SHOCK ABSORBER CYLINDER (13) WHICH, IN turn, GOES TOGETHER WITH THE TREFILATION PAD AND, THROUGH THIS, TO THE SHEET PILLOW (7).
