    Abstract: The method for producing an aluminum wheel rim comprises axially pressing a thin walled cylindrical aluminum or aluminum alloy material under the action of compressive stress acting thereon through tapered portions of a die and a punch cooperating therewith in a press machine so that the diameter of the material is enlarged so as to form the required configuration of the rim, while the wall thickness of the material is increased at positions where compressive stress is applied through the tapered portions of the die and the punch thereby increasing the mechanical strength of the material at positions where otherwise weakening tends to occur due to the thinning of the wall thickness of the material by the roll working thereof. In order to successfully carry out the method, it is preferred to select the ratio H/D of the height H of the material with respect to the inner diameter D thereof to be equal to or less than 1.5, the ratio t/D of the wall thickness t of the material with respect to the inner diameter D to be in the range of 0.006 to 0.06 and the mean deformation resistance or mean flow stress of the material to be in the range of 10 to 25 kg/mm.sup.2, while the inclination angle of the tapered portions of the die and the punch is set to be in the range of 10.degree. to 65.degree..

    Abstract translation: 制造铝轮辋的方法包括在作用于其上的压缩应力的作用下轴向挤压薄壁圆柱形铝或铝合金材料，所述压缩应力通过在冲压机中与其配合的模头和冲头的锥形部分，使得材料的直径 被扩大以形成轮辋所需的构造，同时在通过模具和冲头的锥形部分施加压应力的位置处增加材料的壁厚，从而增加材料在如下位置处的机械强度： 否则由于通过其辊加工使材料的壁厚变薄，往往会发生弱化。 为了成功地实施该方法，优选选择材料的高度H相对于其内径D的比率H / D等于或小于1.5，比例t / D 相对于内径D的材料的壁厚t在0.006〜0.06的范围内，并且材料的平均变形抗力或平均流动应力在10〜25kg / mm2的范围内，而倾斜 模具和冲头的锥形部分的角度设定在10°至65°的范围内。

    Abstract: A method and apparatus for forming metal wheel assemblies having a rim and attached spider. A pair of outer dies complementary to the final radial form of the wheel rim are moved together to enclose an annular metal workpiece. A pair of horizontally opposed conical dies are then moved interiorly of the outer dies and annular workpiece. Each conical die has an annular stuffing ledge which contacts the edge of the workpiece. Force is then exerted against the workpiece edges so as to plastically regenerate the workpiece between the conical dies and outer dies; thus, providing thickening of the material in desired areas. A spider extending across the workpiece is axially loaded with the conical dies causing plastic deformation of the spider. A center rod mounted to and projecting from one of the conical dies is concentric with the conical dies and extends through the spider as the spider plastically deforms therearound. A groove formed in one of the conical dies forms a seating ridge in the spider which is defined by a plane perpendicular to the longitudinal axis of the wheel rim. A plurality of seating bosses are formed into the spider by the conical dies.

    Abstract: The present invention provides a wheel and manufacturing method of the same which make it possible to prevent the formation of indentations along the hump parts in the inner circumferential surface of the rim. In a wheel which comprises a cylindrical rim consisting of a rolled metal plate, and in which hump parts that are used to lock the inner circumferential edge part of the tire are disposed circumferentially so that these hump parts protrude to the outside in the vicinity of the end part of the outer circumferential surface of the rim on at least the design surface side, the outer hump part is formed to have an increased thickness by damming so that this outer hump part protrudes outward while the inner circumferential surface of the rim that corresponds to the outer hump part is formed into a flat circumferential surface.
