Abstract

Se proporciona un método para la conformación de una lámina en bruto, el método siendo capaz de mejorar tanto rendimientos como conformabilidad. El método para la conformación de una lámina en bruto 1 incluye conformar la lámina en bruto 1 en una forma de preformado mediante deformación plástica y a continuación deformar plásticamente la lámina en bruto 1 de la forma de preformado en una forma final. La forma de preformado se determina de modo que, en cada una de secciones transversales en la forma final, la relación (L1/L0) de una longitud de línea de sección transversal L1 en la forma de preformado a una longitud de línea de sección transversal L0 en la forma final en la misma posición de sección transversal cae dentro de un intervalo de tolerancia predeterminado.
