Abstract:To meet requirement of intelligent, green and rapid processing of nickel starting sheet in one nickel smelter, optimal design of nail ear of nickel starting sheet was carried out. Causes of rate drop of ear were analyzed. A new nailing mode processing method is designed, i.e, nickel starting sheet is put into working position of nailing ear, left ears are automatically added, and pressing force during ear nailing is simulated analyzed to confirm the best solution. Meanwhile, ear feeding step is also optimized. With consideration of convenience and feeding safety, all left side of nickel starting sheets missing the ear are ensured through plate turn-over by manipulator. The pilot results show that ear dropping rate drops from 5% to 0 after optimization.
