Title:
FRONT AXLE BEAM AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2018/186380
Kind Code:
A1
Abstract:
The disclosed method of production of the present invention is a method for producing a front axle beam. This production method comprises a die forging step and a bending step. The die forging step comprises using a die to forge steel and thereby form a forged article that includes a rough web section to serve as a web section, and four rough flange sections of a plate-like shape that protrude out toward the front and rear from an upper end and lower end, respectively, of the rough web section. The bending step comprises pressing, with a first die (310), at least one specific rough flange section of the four rough flange sections, and thereby forming, on the specific rough flange section, a bend section (232) that bends toward the inside in a vertical direction (VD) of a forged article (201).
