推力轴承工艺与工装的改进

Improvement of thrust bearing technology and tooling

针对推力轴承加工过程中存在的锻造工艺落后、留量大、精度差、切断宽度大等问题,对锻造工艺进行了改进,由自由锻4件合锻改为碾环锻造8件合锻,减少了加工留量,提高了效率;工件分离由车刀切断改为锯片锯断,减少了切断留量和端面留量,节约了原材料,提高了加工工效,降低了生产成本;对锯床进行了技术改造,并制作了新工装,为工艺改进奠定了基础。

In view of the problems in the process of machining thrust bearing such as the backward forging process, big allowance, poor precision and big cutting off width,etc, the forging process was improved, 4 pieces combined forging by free forging were changed to 8 pieces combined forging by rolling forging to reduce the machining allowance and improves the efficiency;workpiece was separated by the blade sawing instead of turning to cut off to Reduces the cutting allowance and end face allowance,save raw materials, improve the machining efficiency and reduce the production cost; sawing machine for the technical reformation, and making the new tooling, which laid a foundation for process improvement.
