Abstract：

For the problems of flash at parting surface，out-of-flatness and longitudinal flash in the rotary forming of automobile half-axle flange, the half-axle flange was produced by the hydraulic press closed die forging, and its forging process was simulated by the finite element numerical simulation. Based on the filling effect, finish forging temperature field, the load-stroke, equivalent strain and equivalent stress distribution, the forming technology was verified, and the die structure was optimized. Then, the half-axle flange forging was produced by hydraulic press, which showed a good agreement with numerical simulation results, the forming products met the design requirements with high dimensional accuracy and reliable quality. The result show that the existing defects are basically eliminated comparied to the original technology, as well as the rough machining is avoided because of good product consistency.
