《轴承》1973年第4期曾刊载过我厂“用65Mn钢丝制作弹簧锁圈”一文,其要点是用绕簧压扁工艺制造102605轴承的弹簧锁圈,取代旧的弹簧钢板裁环工艺。在上文所阐明的工艺基础上,我们又研究成功冷轧扁绕簧新工艺,比前两种工艺更经济合理,能显著提高材料利用率和劳动生产率、降低生产成本,减轻劳动强度。冷轧扁绕簧工艺见表1。三种工艺的钢材利用率对比见表2。 “Bearing” No. 4, 1973 has published my factory “with 65Mn wire making a spring lock ring,” a text whose main point is to use spring around the flattening process to create 102605 bearing spring lock ring to replace the old spring steel cutting ring process. Based on the process explained above, we also study the successful new cold-rolled flat spring technology, more economical than the previous two processes, can significantly improve material utilization and labor productivity, reduce production costs, reduce labor intensity. Cold-rolled flat spring process shown in Table 1. Three kinds of steel utilization comparison of technology in Table 2.
