Abstract

[Objetivo] Es suprimir la presencia de pliegues debido a la deformación del rebordeado por contracción y la presencia de grietas debido a la deformación del rebordeado por estiramiento cuando una placa de metal de alta resistencia es estampada a un componente curvado longitudinalmente. [Solución] Un método de estampado para suprimir una presencia de pliegues debido a la deformación del rebordeado por contracción de un componente curvado longitudinalmente que tiene una sección transversal en forma de sombrero o en forma de U, caracterizado porque el movimiento de un material como una parte de una pieza troquelada desde una porción de borde hasta una porción de pared vertical se suprime para mover preferentemente el material desde una porción superior hasta la porción de pared vertical mientras causa deformación del rebordeado por estiramiento en el material, mientras que una línea de cresta como un límite entre una porción superior y una porción de pared vertical se inclina con respecto a una dirección de estampado para rotar un material como una parte de una pieza troquelada sostenida por un conjunto de troqueles durante el estiraje para moverse en una dirección longitudinal del componente y la rotación se suprime para provocar la deformación por compresión dentro de una cara en la dirección longitudinal del componente, y la presencia de pliegues en porción de borde y la porción superior del material se suprime con el conjunto de troqueles.[Objective] It is to suppress the presence of folds due to deformation of the contraction flange and the presence of cracks due to deformation of the stretch beading when a high strength metal plate is stamped to a longitudinally curved component. [Solution] A stamping method to suppress a presence of folds due to the deformation of the flange by contraction of a longitudinally curved component having a hat-shaped or U-shaped cross section, characterized in that the movement of a material such as a part of a die-cut piece from an edge portion to a vertical wall portion is suppressed to preferably move the material from an upper portion to the vertical wall portion while causing deformation of the beading by stretching in the material, while a crest line as a boundary between an upper portion and a vertical wall portion bends with respect to a stamping direction to rotate a material as a part of a die piece held by a set of dies during stretching to move in a longitudinal direction of the component and the rotation is suppressed to cause deformation by co Printing within a face in the longitudinal direction of the component, and the presence of folds in edge portion and the upper portion of the material is suppressed with the set of dies.
