Abstract

PROCESO PARA LA FABRICACION DE UNA LLAVE (1) CON ANILLO ABIERTO POR DEFORMACION DEL CUERPO BRUTO DE LA LLAVE (1) MEDIANTE UNA OPERACION DE PRENSADO, DEJANDO UN EXCESO DE METAL A LO LARGO DE LA PERIFERIA DE LA BOCA DE LA LLAVE (4) Y MECANIZADO FINO POSTERIOR DE LA BOCA (4), POR EJEMPLO, MEDIANTE UNA OPERACION DE BROCHADO, PARA DETERMINACION DE LA FORMA INTERNA DE LA BOCA DE LA LLAVE (4) FORMADA POR CUATRO LADOS Y CON EJECUCION POSTERIOR DE UNA DEFORMACION LOCAL PLASTICA EN COINCIDENCIA CON UNA SUPERFICIE LATERAL DE LA LLAVE, LA CUAL LIMITA LA BOCA DE LA LLAVE FORMADA POR CUATRO LADOS, PARA CREAR POR ELLO UN ENGROSAMIENTO (7) QUE SE EXTIENDE EN DIRECCION DE LA PERIFERIA DE LA BOCA DE LA LLAVE, QUE SIRVE COMO APOYO DE LA LLAVE (1) SOBRE LA TUERCA A ACCIONAR.PROCESS FOR THE MANUFACTURE OF A KEY (1) WITH AN OPEN RING DUE TO DEFORMATION OF THE GROSS KEY BODY (1) THROUGH A PRESSING OPERATION, LEAVING AN EXCESS OF METAL ALONG THE PERIPHERY OF THE MOUTH OF THE KEY (4) AND FINAL MACHINING POSTERIOR OF THE MOUTH (4), FOR EXAMPLE, THROUGH A BROACHING OPERATION, FOR DETERMINATION OF THE INTERNAL FORM OF THE MOUTH OF THE KEY (4) FORMED BY FOUR SIDES AND WITH POST-EXECUTION OF A LOCAL PLASTIC DEFORMATION IN COINCIDENCE WITH A LATERAL KEY SURFACE, WHICH LIMITS THE KEY MOUTH FORMED BY FOUR SIDES, TO CREATE THEREFORE A THICKENING (7) THAT EXTENDS IN THE DIRECTION OF THE KEY MOUTH PERIPHERY, WHICH SERVES AS SUPPORT FOR THE KEY (1) ON THE NUT TO BE ACTUATED.
