    • An improved wheel rim expanding tooling apparatus includes an inboard and an outboard wheel rim expanding tooling assembly. The inboard wheel rim expanding tooling assembly includes a plurality of segmented inboard press members each including a pair of side surfaces. The side surfaces include a first outer section and a second inner section. The first outer section extends radially inwardly a first radial distance and the second inner section extends radially inwardly a second radial distance which is greater than the first radial distance. The first outer section of the inboard press members is provided with a generally curved surface profile which extends across at least a portion of an axial width thereof. The outboard wheel rim expanding tooling assembly includes a plurality of segmented outboard press members each including a pair of side surfaces. The side surfaces include a first outer section and a second inner section. The first outer section extends radially inwardly a first radial distance and the second inner section extends radially inwardly a second radial distance which is greater than the first radial distance. The first outer section of the outboard press members is provided with a generally curved surface profile which extends across at least a portion of an axial width thereof.
    • 改进的轮辋膨胀工具装置包括内侧和外侧轮辋膨胀工具组件。 内侧轮辋膨胀工具组件包括多个分段的内侧压力构件,每个包括一对侧表面。 侧表面包括第一外部部分和第二内部部分。 第一外部部分径向向内延伸第一径向距离,并且第二内部部分径向向内延伸第二径向距离,其大于第一径向距离。 内侧按压构件的第一外部部分设置有大致弯曲的表面轮廓,其横跨其轴向宽度的至少一部分延伸。 外侧轮辋膨胀工具组件包括多个分段的舷外按压构件,每个包括一对侧表面。 侧表面包括第一外部部分和第二内部部分。 第一外部部分径向向内延伸第一径向距离,并且第二内部部分径向向内延伸第二径向距离,其大于第一径向距离。 舷外按压构件的第一外部部分设置有大致弯曲的表面轮廓,其横跨其轴向宽度的至少一部分延伸。
