Abstract

Un cuerpo tubular principal (12) de un tubo curvado (10) tiene una trayectoria de flujo que sigue una línea de eje (12A), e incluye una porción doblada (14) en una porción en una dirección a lo largo de la línea de eje (12A). También, en una periferia interior (14A) dentro de una dirección de flexión de la porción doblada (14) en el cuerpo tubular principal (12), una porción cóncava (16) se forma como una porción transversal ampliada a lo largo de una dirección de la línea de eje (12A). A propósito, en un troquel interior de un troquel para formar un tubo curvado, un núcleo de bisagra que forma la porción cóncava (16) se inserta en una porción de ranura de un núcleo principal, y el núcleo principal se mueve en una dirección de posición de retracción, de manera que una porción de punta del núcleo de bisagra, que tiene una forma que se acopla con la periferia interior (14A) dentro de la dirección de flexión de la porción doblada (14), cambia a una posición de formación del núcleo principal.
