Abstract

FORMACION DE UN EXTREMO REBORDEADO EN UNA PIEZA TUBULAR UTILIZANDO UN TROQUEL (14) CON UNA ENTRADA (16) QUE TIENE UNA SUPERFICIE DE TOPE (16C) QUE SE EXTIENDE TRANSVERSALMENTE A CADA LADO DE LA ENTRADA. LA PIEZA (11) SE COLOCA EN LA ENTRADA DE FORMA QUE TIENE UN EXTREMO ADYACENTE A LA SUPERFICIE DE TOPE. UN MANDRIL DE EXPANSION TRANSVERSAL (18) SE INSERTA PLEGADO EN EL EXTREMO DE LA PIEZA. EL MANDRIL TIENE UN PAR DE MORDAZAS SEPARABLES LATERALMENTE (18), CADA UNA DE LAS CUALES SE PUEDE MOVER A UNA POSICION EN LA QUE SE SUPERPONE A UNA SUPERFICIE DE TOPE RESPECTIVA (16C), Y UNA CUÑA (21) QUE REACCIONA ENTRE DICHAS MORDAZAS (18) PARA SEPARARLAS LATERALMENTE. LA CUÑA (21) SE EXTIENDE PARA SEPARAR DICHAS MORDAZAS (18) Y EXPANDE LA PARED LATERAL (12B) DE LA PIEZA (11) TRANSVERSALMENTE HACIA FUERA PARA SUPERPONER LAS SUPERFICIES DE TOPE (16C). LAS MORDAZAS (18), A CONTINUACION, SE JUNTAN EN SU ESTADO EXPANDIDO LONGITUDINALMENTE HACIA DENTRO PARA SUJETAR UNA PARTE (12C) DE CADA PARED LATERAL EXPANDIDA (12) ENTRE UNA CARA EXTREMA DE CADA PIEZA DE LA MORDAZA (18A) Y LA RESPECTIVA SUPERFICIE DE TOPE (16C), CREANDO ASI UNA PARTE REBORDEADA (12) A CADA LADO DE LA PIEZA.
