FRONT AXLE BEAM AND METHOD FOR PRODUCING SAME

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 si...

Zusammenfassung:	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.
