文中介绍了该厂锻工车间技术改造的一些成果:1.推力球轴承套圈的冷冲压。与过去的热冲压相比,冷冲压工艺不仅提高了锻件质量,还可提高冲压效率,留量降到1.5～2毫米,改善劳动条件;2.采用套料工艺时,在原有模具基础上加装两个必55毫米的导柱及导套,可保证内圈壁厚差在0.2～0.5毫米范围内;3.加热炉推料机械化。附图4幅。
The paper introduces some achievements of the factory forging workshop technical innovation: 1. Thrust ball bearing rings cold stamping. Compared with the hot stamping in the past, the cold stamping process not only improves the quality of the forging, but also raises the stamping efficiency, reduces the deposit to 1.5 to 2 millimeters and improves the working conditions. 2. When using the nesting process, on the basis of the original mold Installed two will be 55 mm guide posts and guide sleeve, the inner wall thickness difference can be guaranteed within the range of 0.2 ~ 0.5 mm; 3. Heating pusher mechanization. Figure 4 Figure.
