    • An improved method for fabricating a vehicle wheel (2) from a one-piece sheet metal blank (10) involves a nine station transfer die. In a first station, a sheet metal blank is drawn into a dish-shaped wall (12), a cylindrical outside wall (14), a first contour (16), and a first side wall (18). In the second station, the dish-shaped wall is reverse drawn to form a hub (22) and an inside wall (10), and a valve hole (24) is punched into the first contour. In the third station, the hub is flattened to be substantially perpendicular to an axial centerline of the partially fabricated wheel, and an outer peripheral edge of the first side wall is trimmed. In the fourth station, the inside wall is laterally formed so as to be in contact with the outside wall, and an outer peripheral edge of the first side wall is wiped over to form a flange. In the fifth station, a second contour is laterally formed. In the sixth station, a first offset and inner and outer hub-stiffening embosses are drawn into the hub. In the seventh station, a second offset is drawn in the hub, and a second side wall is laterally formed to complete a tire engaging rim. In the eighth station a center aperture and a plurality of wheel mounting holes are punched in the hub. Finally, in the ninth station, the center aperture and the wheel mounting holes are extruded, and a plurality of rim-stiffening embosses are laterally formed in the rim.

    • 一种用于从单件金属板坯(10)制造车轮(2)的改进方法涉及九台传送模头。 在第一工位中,将金属片坯料拉入盘形壁(12),圆柱形外壁(14),第一轮廓(16)和第一侧壁(18)中。 在第二站中,盘形壁被反向拉出以形成轮毂(22)和内壁(10),并且将阀孔(24)冲压到第一轮廓中。 在第三站中,毂被平坦化成与部分制造的轮的轴线中心线大致垂直,并且修整第一侧壁的外周边缘。 在第四站中,内壁横向地形成为与外壁接触,并且第一侧壁的外周边缘被擦拭以形成凸缘。 在第五站中,横向形成第二轮廓。 在第六站中,将第一偏移和内外轮毂加强压花拉入轮毂。 在第七站中,第二偏移被画在轮毂中,并且第二侧壁横向地形成以完成轮胎接合边缘。 在第八站中,中心孔和多个轮安装孔在轮毂中冲压。 最后,在第九工位中,中心孔和车轮安装孔被挤出,并且在边缘中横向形成多个轮辋加强压花。
