上海红星轴承厂的冷挤压塔形套料工艺,能一次生产出轴承内、外套圈,经数十万件生产考核。该工艺成套材料利用率56.4％(热锻为33.1％),每套加工费可节约17.3％,每套可节约能能源40％以上。此外,由于成品精度高,可减少后续加工时间,提高生产效率,降低成本。在轴承钢的冷挤压研究方面,该工艺目前居国内先进水平。应用轴承冷挤压复合料成形工艺,由于加工中金属处于双向自由流动状态,单位挤压力 Shanghai Hongxing Bearing Factory cold extrusion tower nesting process, to produce a bearing, the outer ring, after hundreds of thousands of production assessment. The utilization of complete sets of materials of the process is 56.4% (hot forging is 33.1%), each processing fee can save 17.3% and each set can save more than 40% of energy. In addition, due to high precision finished products, can reduce the follow-up processing time, improve production efficiency and reduce costs. In the cold extrusion of steel research, the current domestic advanced level. Application of cold extrusion bearing compound forming process, due to the metal in the process of two-way free flow, the unit squeeze pressure
