作者对可伐(镍鉄钴合金)和鋇进行冷引伸试验,分析了板料金相组织,模具几何参数、压边力、润滑等因素对冷引伸性能的影响,并得出了最佳的工艺参数。文中还提出了试验程序图表以及模具设计的资料。 本试验是在南京航院进行。试验材料与工艺装备由南京电子管厂供应。
The authors carried out cold-drawing tests on Kovar and barium, and analyzed the influence of the metallographic structure of the sheet metal, the geometrical parameters of the die, blank holder force and lubrication on the cold drawing performance and obtained the best process parameter. The article also presents the test procedure chart and the mold design information. This test is carried out in Nanjing Airlines. Test materials and process equipment supplied by the Nanjing Tube Factory.
