Abstract

The present invention relates to a method for forming a reinforcement structure, and the reinforcement structure. The method for forming a reinforcement structure according to the present invention may include: a first forming step of bending an edge of a steel plate in a first direction to form a side flange, which forms a flange angle with the bottom surface of the steel plate; a second forming step of bending the steel plate in a second direction to form a pair of side wall flanges, and bending at least a portion of the side flange in a direction opposite the first direction; and a third forming step of bending the side flange in the first direction.

Description

technical field [0001] The invention relates to a forming method of a reinforced structure and the reinforced structure. Background technique [0002] Many components forming a vehicle may have various flange configurations for joining related components. [0003] figure 1 A conventional vehicle structural part 10 is schematically shown, wherein the vehicle structural part 10 formed by forming a steel plate may have connections bent into Shaped side wall flange 10b and lower flange 10a structure. [0004] However, if figure 2 As shown, in the process of stamping and forming such a structural member 10, the deformation is concentrated at the flange corner 11 where the side wall flange 10b and the lower flange 10a intersect. [0005] Since the flange corner portion 11 where the deformation is concentrated is easily deformed or broken, as image 3 As shown, the notch portion 12 is typically formed by cutting a flange corner portion of the structural component 10 . [00...
