    • 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.

    • Expanding apparatus (10) and method for sizing a one-piece drop-centre wheel rim (20) having first and second ganged arrays (50,52) of rim sizing die segments insertable into the rim from one side thereof, and a third array (54) of rim sizing die segments insertable into the opposite side of the rim, all three arrays cooperating to form a complete array of die segments for expansion sizing of the rim. A single wedge mechanism (60) moves the arrays radially outwardly to individually size the inboard bead seat (32), outboard bead seat (24) and drop-centre well (28) zones of the rim in response to relative coaxial movement of the wedge and arrays in a rim expansion working stroke along a longitudinal axis of the wedge. The wedge includes an expansion cone mechanism comprising first, second and third cone-cams (200,202,204) respectively individually operably associated with the first, second and third die arrays for radially expanding the same in such working stroke. A set-up adjustment mechanism disposed interiorly of the wedge has three concentrically arranged lead screws (210,212,214) individually threadably coupled to each of the cone cams for carrying and selectively positioning the same along the longitudinal axis of the wedge to thereby vary the set-up end limit of radially outward movement of the associated die segment array for a given relative working stroke of the wedge means and arrays. A gear drive (300,302) coupled to the exterior end of each lead screw individually rotates, and is driven either manually or by servo motors operably coupled to each worm gear drive. Cone cam position sensors (320,322,324) each develop a signal indicative of the axially adjusted set-up position of each associated cone cam. A signal processing control system (313) utilizes the signals for controlling the servo motors to drive the cone cams and thereby control their adjusted set-up positions.
    • 扩张装置(10)和用于确定具有可从其一侧插入轮辋中的轮辋尺寸化模具段的第一和第二联动阵列(50,52)的单件式下垂中心轮辋(20)的尺寸的方法和第三阵列 (54)可插入轮辋的相对侧中,所有三个阵列协作以形成用于扩大轮辋尺寸的模具段的完整阵列。 单个楔形机构(60)响应楔形物的相对同轴运动而径向向外移动阵列以单独确定轮辋的内侧胎圈座(32),外侧胎圈座(24)和落下中心井(28) 并且沿楔形物的纵向轴线排列在轮辋膨胀工作冲程中。 该楔包括膨胀锥机构,该机构包括分别与第一,第二和第三模具阵列分别可操作地相关联的第一,第二和第三锥形凸轮(200,202,204),用于在该工作冲程中使其径向膨胀。 设置在楔块内部的装配调节机构具有三个同心布置的导螺杆(210,212,214),每个导螺杆(210,212,214)分别螺纹连接到每个锥形凸轮上,以沿着楔块的纵向轴线承载和选择性地定位它们,从而改变设置 对于楔形装置和阵列的给定相对工作行程,相关联的模具段阵列的径向向外移动的终点限制。 联接到每个导螺杆的外端的齿轮传动装置(300,302)单独地旋转,并且手动地或通过可操作地联接到每个蜗轮传动装置的伺服马达来驱动。 锥形凸轮位置传感器(320,322,324)各自产生表示每个相关锥形凸轮的轴向调整的设置位置的信号。 信号处理控制系统(313)利用这些信号来控制伺服电动机来驱动锥形凸轮并由此控制它们的调整的设置位置。
