Technology of Magnesium Alloy Car’s Wheel Hub on Spinning Shaping

Abstract:

Take magnesium alloy car’s wheel hub as the investigated subject, and based on the advanced technology of magnesium alloy car’s isothermal spinning shaping, the equipment of spinning shaping was developed. The continuous and partial plastic deformation process of wheel hub radials were numerically simulated through finite element method, and deformation regulations were also analyzed and process parameters were optimized by orthogonal tests. The results of the experiments showed that this new technology significantly increased the size of continuous deformation zone, made deformation paths reasonable, and greatly improved shaping efficiency and machining accuracy.
