    Abstract: A wheel disk has a circumferential profile formed with crenellations. The depth of the crenellations is maximum adjacent to the hub and ranges from the maximum down to zero adjacent to the rim. In making a wheel disk, a generally cylindrical tube is formed, the tube is widened at one end to form a border free of undulations, and the other end of the tube is folded down to impart to the central portion of the disk the desired final configuration. The tube is inserted for the folding operation between a ring of punches and a ring of counterpunches. The punches are pivoted inwardly toward the axis of the ring of punches by a cam plate, and the pivoting of the counterpunches is limited by a second plate.

    Abstract translation: 轮盘具有形成有圆锯齿的圆周轮廓。 锯齿的深度在轮毂附近是最大的,并且范围从邻近轮缘的最大下降到零。 在制造轮盘的过程中,形成一个大致圆柱形的管,一端加宽该管,形成一个没有起伏的边界,另一端向下折叠,以便将盘的中心部分赋予所需的最终 组态。 插入管子用于冲压环和对立环之间的折叠操作。 冲头通过凸轮板朝向冲孔环的轴线向内枢转,并且对接件的枢转由第二板限制。
