新昌县轴承厂在上海交大等单位的协助下,试验成小型轴承套圈套料复合冷挤压新工艺,为我国轴承行业在小型轴承套圈加工方面开创了新的途径。去年十二月十六日由省机械厅组织通过了技术鉴定。采用该工艺,可节省热锻造时所需的全部能源,提高材料利用率,同时,由于该工艺单位挤压力为160公斤/毫米~2,比单圈反挤压降低一半左右,因此,使模具受力条件大为改善,使用寿命提高,设备吨位相应减小,从而使轴承的成本降低。经该厂201轴
Xinchang Bearing Factory in Shanghai Jiaotong University and other units with the help of pilot into a small bearing ring sets of materials composite cold extrusion new technology for the bearing industry in China in the small bearing rings processing opened up a new way. December 16 last year, organized by the Provincial Department of Machinery passed the technical appraisal. The process can save all the energy required for hot forging and improve the material utilization rate. Meanwhile, the extrusion force of the process unit is 160 kg / mm ~ 2, which is reduced by about half compared with the single-ring reverse extrusion. Therefore, Mold greatly improved the stress conditions, improve service life, equipment, corresponding reduction in tonnage, so that the bearing costs. After the plant 201 axis
