Two-stage aging heat treatment method for aluminum alloy wheel

The invention belongs to the technical field of aluminum alloy, and relates to aluminum alloy wheel processing, in particular to a two-stage aging heat treatment method for an aluminum alloy wheel, which comprises the following steps: feeding, furnace entering, solution treatment (heating and heat preservation), discharging, quenching, furnace entering, first-stage artificial aging treatment (heating and heat preservation), discharging, second-stage artificial aging treatment (heating and heat preservation) and discharging. Wherein the primary artificial aging treatment is incomplete aging, the aging temperature is 130-140 DEG C, and the aging time is 2-2.5 h; the secondary artificial aging treatment is complete aging, the aging temperature is 170-180 DEG C, and the aging time is 2-2.5 h. According to the two-stage aging heat treatment method disclosed by the invention, the internal structure of the product is sufficiently subjected to solid solution while the strength of the product is ensured, and the mecha
