FORGING PROCESS OF MAGNESIUM ALLOY WHEEL HUB

The forging process of a magnesium alloy wheel hub comprises the following steps: step 1, heating a magnesium alloy bar to 350420°C and keeping the temperature for 20 minutes; step 2, forging and forming the bar under a 6000-ton forging press, and controlling the forging process in sections. The forging process of the invention adopts sectional control, different forging process parameters are adopted in different forging stages, so that magnesium alloy bars can exert maximum forgeability in different deformation stages, make magnesium alloy deformation process more continuous, make forging process easier, obtain forged magnesium alloy wheel hub with excellent properties, and greatly improve forging process and processing efficiency.
