Abstract

SE DESCRIBE UN METODO PARA FORMAR UNA CAVIDAD DE SUJECION (44) EN EL EXTREMO TERMINAL DE UNA VARILLA DE COMBUSTIBLE NUCLEAR (42) QUE INCLUYE LOS PASOS BASICOS DE SUMINISTRAR UN CONECTOR TERMINAL (46) CON UN ORIFICIO INTERNO (48) DE DIAMETRO UNIFORME QUE SE ABRE EN UN REBORDE ANULAR EXTERNO (50) EN EL EXTREMO TERMINAL DEL CONECTOR; FORMAR UN CONECTOR TERMINAL INTERMEDIO (52) EN EL QUE EL REBORDE EXTERNO ANULAR (50) ES TRANSFORMADO EN UN REBORDE EXTERNO CONICO (54) QUE TIENE SUPERFICIES INTERNAS REDONDEADAS (56) QUE DEFINEN UNA ABERTURA DE ENTRADA EN EL ORIFICIO INTERNO (48) DE UN DIAMETRO MENOR QUE AQUEL DEL ORIFICIO INTERNO; Y LA EXTRACCION DE UNA CAPA EXTERNA (60) DE MATERIAL DEL CONECTOR TERMINAL INTERMEDIO (52) Y UNA CAPA INTERNA DE MATERIAL DE LA SUPERFICIE INTERNA REDONDEADA (56) DEL REBORDE EXTERNO CONICO (54) PARA PRODUCIR UN CONECTOR TERMINAL ACABADO QUE TIENE UNA CAVIDAD INTERNA DE SUJECION (44) COMPUESTA DE UN ORIFICIO INTERNO (48), UNA SUPERFICIE INTERNA CILINDRICA (64) QUE DEFINE UNA ABERTURA DE ENTRADA (58) A LA ABERTURA INTERNA (48) Y QUE ES DE UN DIAMETRO MENOR QUE LA ABERTURA INTERNA.
