E形保持架翻边后应保证两面的材料厚度一致,以免轴承运转时纲球与保持架单面接触,影响旋转灵活性、产生嗓声和剧烈磨损等。本文所阐述的翻边工艺与相应的苏联工艺相比可使两面的材料厚度基本一致。保持架是采用管料并利用横向冲压工艺完成翻边的。文中对翻边模模具的结构特点、设计要求和使用情况等作了简要说明与计算。附图10幅 E-shaped cage Flanging should ensure that both sides of the material thickness of the same, so as not to run the ball bearing and cage single-sided contact, affecting rotation flexibility, resulting in noise and severe wear and tear. The flanging process described in this paper can make the thickness of the material on both sides basically the same as the corresponding Soviet technology. Cage is the use of pipe material and the use of horizontal stamping process to complete the flange. In the paper, the structural characteristics, design requirements and usage of flange mold are briefly described and calculated. Figure 10 Figure
