    摘要： In a pressing step, a first forged product (201) is pressed by a first die (310), and thereby, a second forged product (202) including a rough flange (241) having a thickness-changing portion (141) is produced. The thickness-changing portion (141) includes a front part protruding frontward from a side of a rough web part (220) and a rear part protruding rearward from the side of the rough web part (220). Each of the front part and the rear part includes a first part, and a second part that is thicker than the first part and is located farther from the rough web part than the first part. In the pressing step, at least a part of the rough flange that is above or below the web part (thick part) is pressed by the first die (310), whereby the material of the first forged product in the part is caused to flow frontward and rearward, and the thickness-changing portion (141) is formed.

    摘要： The production method disclosed includes a first step, a second step and a third step to be performed in this order. In the first step, a steel material is forged by dies, whereby a forged product including a rough web part (220) and four plate-shaped rough flange parts is produced. In the second step, at least one specified rough flange part, which is at least one of the four rough flange parts, is pressed by a first die, whereby a first bent portion bending outward in an up-down direction VD of the forged product is formed in the specified rough flange part. In the third step, the edge of the first bent portion is pressed by a second die (320) inward in the up-down direction VD, whereby the edge is deformed and a second bent portion (232b) is formed. In the third step, the edge of the specified flange part is deformed while the edge is kept from deforming in a front-rear direction HD.

    摘要： The production method disclosed is a method for producing a front axle beam. The production method includes a die forging step and a bending step. The die forging step is a step of forging a steel material with dies to produce a forged product including a rough web part, which is to be formed into a web part, and four plate-shaped rough flange parts protruding frontward and rearward from an upper side and a lower side of the rough web part, respectively. The bending step is a step of pressing at least one specified rough flange part, which is at least one of the four rough flange parts, with a first die (310) to form a bent portion (232) in the specified rough flange part such that the bent portion is bent inward in an up-down direction (VD) of the forged product (201).

    摘要： A disclosed front axle beam (100) includes a beam section (110). The beam section (110) includes a first flange part (131), a second flange part (132), and a web section (120) connecting the first flange part (131) and the second flange part (132). The web section (120) includes a varying-slope section (121) that includes a plurality of first slope sections and a plurality of second slope sections. Each of the plurality of first slope sections inclines in one direction with respect to the vehicle-height direction in a cross section perpendicular to the longitudinal direction (LD). Each of the plurality of second slope sections inclines in the opposite direction to the one direction with respect to the vehicle-height direction in a cross section perpendicular to the longitudinal direction (LD). The first slope section and the second slope section are located in an alternate manner along the longitudinal direction (LD). In this way, the rigidity of the front axle beam (100) can be increased.
