Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE ELECTRODOS PARA BUJIAS DE ENCENDIDO ASI COMO ELECTRODOS DE BUJIAS DE ENCENDIDO. LA INVENCION CONCIERNE A UN PROCEDIMIENTO PARA LA FABRICACION DE UNA BOBINA DE ENCENDIDO RESISTENTE Y DE LARGA DURACION PARA MOTORES DE COMBUSTION INTERNA. EL ELECTRODO (16) DE LA BUJIA DE ENCENDIDO DE LA INVENCION SE COMPONE DE VARIAS PIEZAS INICIALES: UNA PIEZA INICIAL PARA UNA ENVOLTURA (31'') RESISTENTE A LA CORROSION, UNA PIEZA INICIAL PARA UN NUCLEO (33'') DE ELEVADA CONDUCTIVIDAD TERMICA Y UNA PIEZA INICIAL PARA UNA ZONA RESISTENTE A LA COMBUSTION (32''). ESTAS PIEZAS INICIALES SE EXTRUSIONAN EN FRIO CONJUNTAMENTE EN UNA PIEZA BRUTA DE ELECTRODO, QUE SE MOLDEA A UN ELECTRODO CENTRAL (16) TRABAJANDO SU CABEZA (51) Y SU ZONA QUE DA AL LADO DE LA CAMARA DE COMBUSTION. LOS ELECTRODOS SOMETIDOS A UN ESPECIAL ESFUERZO RECIBEN UNA CUARTA PIEZA INICIAL QUE TAMBIEN SE DEBE EXTRUSIONAR EN FRIO, QUE SE COMPONE DE MATERIAL ALTAMENTE RESISTENTE A LA COMBUSTION Y QUE EN EL LADO DE LA CAMARA DE COMBUSTION AUN ESTA DISPUESTO POR DELANTE DE LA ZONA (32'') RESISTENTE A LA COMBUSTION. EL ELECTRODO (16) SE PUEDE UTILIZAR COMO ELECTRODO CENTRAL (16) Y, DADO EL CASO, DESPUES DE UN PROCESO DE TROQUELADO PLANO Y FLEXION, TAMBIEN COMO ELECTRODO DE MASA.
