    • A method for making a drive axle shaft (10) is provided. A tubular blank (40) is inserted in a first die (42) including an orifice (54). The tubular blank (40) is extruded through the orifice (54) to form an elongate tubular body (12) with a longitudinal axis (16). A first longitudinal end (18) of the tubular body (12) is heated. The tubular body (12) is inserted into a bore (80) in a support apparatus. The support apparatus defines a second die (84) at one end (86) surrounding the bore (80), and the first longitudinal end (18) of the tubular body (12) projects outwardly from the bore (80). A third die (100) comprises a mandrel (102) configured to be received within the tubular body (12). A wheel flange (14) is formed by moving at least one of the support apparatus and the third die (100) toward the other of the support apparatus and the third die (100) to deform the first longitudinal end (18) of the tubular body (12) between the second and third dies (84, 100).
    • 本发明提供一种用于制造驱动轴的轴(10)的方法。 管状坯件(40)被插入在第一的(42)包括在孔口(54)。 管状坯料(40)通过孔(54)挤出以形成在细长管状主体(12)具有纵向轴线(16)。 管状体(12)的第一纵向端部(18)被加热。 管状体(12)被插入在支撑装置中的孔(80)。 所述支撑装置以包围所述孔(80)和所述管状主体的第一纵向端部(18)(12)向外突出从所述孔(80)的一端(86)定义的第二的(84)。 第三,在(100)包括被配置成管状体(12)内接收的心轴(102)。 轮缘(14)通过移动所述支撑装置中的至少一个和所述第三形成的(100)朝另一支撑装置和所述第三(100)变形的管状的第一纵向端部(18) 体(12)在第二和第三这(84,100)之间。
