    Abstract: Methods for forming a soft lip for a wheel rim are disclosed herein. The wheel rim may be a cold-formed, spun-formed, or rolled-formed cylindrical blank, wherein the blank includes an upturned outer edge. As the blank is spun, a blunting roller lowered to contact the upturned outer edge to blunt the outer edge into a work-strengthened annular bead, and finish off the external surface of the annular bead to form a soft lip.

    Abstract: There is provided a method for preventing a cylindrical body from buckling in externally curling edges of both side portions by pressing by curling dies in an axial direction after molding the cylindrical body having a drop portion whose outer diameter is small and the both side portions whose outer diameter is large by enlarging a cylindrical material made of aluminum alloy by electromagnetic molding. In curling the edges of the both side portions, a buckling preventing die restrains an outer periphery of the drop portion of the cylindrical body. Because the buckling preventing die receives the axial compression force of the curling dies, it can prevent the cylindrical body from buckling and deforming. The buckling preventing die is what a split die disposed on the side of an outer periphery of the cylindrical material in the electromagnetic molding is used as it is.

    Abstract translation: 提供了一种方法，用于通过在具有外径小的液滴部分的圆筒体成形后，通过在轴向上的卷曲模具进行加压来防止圆柱体在两侧部的外侧卷曲边缘的弯曲， 通过电磁成型扩大由铝合金制成的圆柱形材料，直径很大。 在卷曲两侧部分的边缘的过程中，弯曲防止模具限制了圆柱体的液滴部分的外周。 由于防翘曲模具受到卷边模具的轴向压缩力，因此可以防止圆柱体发生弯曲变形。 抗弯曲模具是直接使用设置在电磁模制中的圆筒形材料的外周侧的分割模具。

    Abstract: An improved method for producing a wheel rim for use in a vehicle wheel. The method includes the steps of: (a) providing at least two individual flat sheets of material having different thicknesses; (b) securing the two flat sheets of material together by welding to form a rim blank; (c) forming the rim blank into a generally cylindrical hoop having a first discrete section defined by one of the two flat sheets of material and a second discrete section defined by the other one of the two flat sheets of material, the first discrete section of the hoop defining a first outer diameter, extending a first axial length, and including a substantially uniform first thickness throughout the entire first axial length thereof, the second discrete section of the hoop defining a second outer diameter, extending a second axial length, and including a substantially uniform second thickness throughout the second axial length thereof; (d) subjecting the hoop to a series of metal forming operations to produce a finished wheel rim having at least one tire bead seat retaining flange and at least one tire bead seat surface.

    Abstract: The invention relates to a method for the manufacture of a rotationally symmetrical part, particularly a vehicle wheel. The starting material is constituted by a circular blank preform, which has a substantially radial base and a connecting, axial shoulder. The shoulder is firstly rolled out by spinning rollers axially on either side of the base to a first web and a second web. At least one of the two webs is spun against a spinning chuck. Subsequently the outer contour of the webs is finally shaped and calibrated in the outer regions.

    Abstract: A vehicle wheel with a roll-formed rim has an interior rim section and axially spaced first and second beadseat sections. A disc is attached at its skirt flange to the first beadseat section. The first beadseat section has radially outward and radially inward surfaces, both angled radially outward from the wheel axis for example at a fifteen degree angle. A roll-formed groove is formed in the radially inward surface of the first beadseat section, the groove having an inwardly facing cylindrical first surface. The skirt flange has an outwardly facing cylindrical first surface, which engages and is press-fit with the groove cylindrical first surface. The skirt flange and rim are then welded. The groove has a second frusto-conical surface adjacent the groove cylindrical surface. The skirt flange may have a second frusto-conical surface to mate with the groove second frusto-conical surface. The skirt flange may have a third frusto-conical surface to mate with the radially inward surface of the first beadseat section.
