Method for forming an axle housing

A method for manufacturing an axle housing is provided to reducing the processing time by forming a projection on a die such that an outer surface of a preliminary mold is curved and a marginal outer diameter is minimized. A method for manufacturing an axle housing comprises the step of piercing(S4), the step of insertion(S5) and the step of pressing(S6). In the step of piercing, a through-hole(103) is formed in a preliminary mold(100) in an upper and lower direction. In the insertion step, the preliminary mold is input into a die(200) and a punch(300) is inserted into the through-hole. In the pressing step, the die is pressured and extruded. A projection is formed on the die. In the piercing step, a taper part(105) is formed at an upper part of the through hole and a flat part(106) is formed at a lower part of the taper part. In the insertion step, a projected portion of the punch is larger than a projected portion of the preliminary mold. The punch includes a peak and a magnification part. In the pressing step, the taper part is in contact with the magnification part, and the flat part is in contact with the peak.
