The invention discloses a magnesium alloy wheel forging forming method. The technological process of the magnesium alloy wheel forging forming method can be summarized as ''twice-squeezing and once-rotating''. The magnesium alloy wheel forging forming method is characterized by comprising the steps that (1), heating is conducted, wherein a round magnesium alloy blank is heated to the forging temperature, and the temperature of a die is controlled to be equal to that of the blank; (2), primary squeezing is conducted, wherein primary forming of spokes and a rim is completed in a closed backward squeezing way, but an outer rim is not formed; (3), final squeezing is conducted, wherein the outer rim is finally formed in a closed forward squeezing way, and backward-squeezing final forming of the rim portion are completed at the same time; and (4), inward rotary squeezing for forming is conducted, wherein flaring of the rim and forming of a folded edge of an inner rim are completed through inward rotary squeezing. The magnesium alloy wheel forging forming method has the advantages that the technological process is simple; the streamline is smooth; the production efficiency is high; the utilization rate of materials is high; the defect of cracking can be effectively avoided in the forming process; and the volume production can be achieved easily.
