Abstract

SE DESCRIBE UN METODO Y APARATO DE CONVERSION PARA LA CONVERSION DE UN COLLAR DE UNA PORCION DE CANTO ALREDEDOR DE UN ORIFICIO VACIO. EL METODO COMPRENDE LA SECUENCIA DE RODEAR LAS PARTES ADYACENTES DE LA PORCION DE CANTO HASTA QUE TODA LA PORCION DEL CANTO HAYA SIDO CONVERTIDA EN EL COLLAR DESEADO. EL APARATO DE CONVERSION COMPRENDE MEDIOS PARA RODEAR EL HUECO Y UN MANDRIL CONVERTIDOR EN EL CUAL LA SUPERFICIE DE ROTACION SE INCREMENTA NO LINEALMENTE DE UNA EXTREMIDAD A OTRA EXTREMIDAD. MOVIENDO EL MANDRIL CONVERTIDOR A TRAVES DEL ORIFICIO PERPENDICULARMENTE A LA SUPERFICIE DEL HUECO Y EN CONTACTO CON LA PORCION DE CANTO GIRANDO DE FORMA ADYACENTE A LAS PARTES DE LA PORCION DEL CANTO.FIG 5.
