摘　　要：针对薄壁轻系列高精密轴承套圈热处理过程中存在严重的淬火变形问题,通过使用半自动淬火压床、优化淬火模具压力,使薄壁套圈的淬火变形率较原工艺大幅降低,可控制在2%～4%,有效提高了产品合格率,降低了劳动强度和生产成本。Aiming at serious quenching distortion problem during heat treatment of rings for thin - walled light series high precision bearings, the semi -automatic quenching press is used and the quenching mould pressure is optimized. The quenching distortion rate of thin - walled rings is greatly reduced and can be controlled within 2% - 4%. The qualified rate of products is effectively improved, and the labor intensity and production cost are reduced.
