Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA ELABORACION DE ELEMENTOS (1) DE CONSTRUCCION METALICOS CON ESPESORES (D{SUB,1} D{SUB,2}) DE PARED DIFERENTES MEDIANTE CONFORMACION DE UN PERFIL (2) DE PARTIDA DE ESPESOR APROXIMADAMENTE REGULAR. LA ZONA (4) A SER CONFORMADA DEL PERFIL (2) DE PARTIDA SE CALIENTA DE MANERA PROGRESIVA POR MEDIO DE UNA FUENTE (5) DE CALOR, DONDE EL PERFIL (2) DE PARTIDA SE AJUSTA BAJO EL INFLUJO DE UNA FUERZA (F{SUB,1}) DE TRACCION QUE ACTUA DE FORMA TRANSVERSAL CON RESPECTO A LA ZONA (9) CALENTADA. LA ALTURA DE LA FUERZA (F{SUB,1}) DE TRACCION APLICADA SE ENCUENTRA POR DEBAJO DEL LIMITE DE FUSION DE MATERIAL PRESENTE EN LA TEMPERATURA AMBIENTE. A TRAVES DEL CALENTAMIENTO FLUYE EN LA ZONA (9) DE CALENTAMIENTO LA LIMITACION DE FLUJO DE FORMA TAN AMPLIA, QUE EL MATERIAL FLUYE BAJO LA SUJECION DE TRACCION ACTIVA. PARA ELLO SE LLEGA A LA APLICACION DE CONFORMACION DEL ELEMENTO (1) DE CONSTRUCCION DE FORMA INMEDIATA EN LA ZONA DE CALENTAMIENTO. LA FUENTE (5) DE CALENTAMIENTO SE MUEVE EN LA DIRECCION DE TRACCION, Y CIERTAMENTE SE CONFORMA CON UNA VELOCIDAD (V{SUB,1}) TAL, QUE SE DISPONE DE UNA ZONA QUE SE ENCUENTRA BAJO EL INFLUJO INMEDIATO DE CALENTAMIENTO DE FORMA CORRESPONDIENTE A LA REDUCCION DE ESPESOR PREVIAMENTE PLANTEADO. CON ELLO SE CONSIGUE UN DESARROLLO DE CONFORMACION PROGRESIVO DE MANERA CONTINUA.
