Production method of hot-formed high-strength steel wheel and cooling device of hot-formed high-strength steel wheel

The invention belongs to the technical field of wheel machining, and particularly relates to a production method and a cooling device of a hot-formed high-strength steel wheel. The welded wheel is put into a heating furnace to be heated to the AC1 point or above, and austenitizing is completed; hot water with the temperature T1 is contained in a water tank of the cooling device, and T1 is larger than or equal to 80 DEG C; the high-temperature wheel is moved into a water tank, spokes are arranged below, and the high-temperature wheel is arranged on a lower die and matched with the lower die; the upper mold is closed downwards to empty hot water in the wheel, after mold closing, the upper mold sprays water to cool the spoke, the water temperature is T2, and the T2 ranges from 10 DEG C to 50 DEG C; by adjusting the water temperature T1 and the water temperature T2, the cooling shrinkage rate of the spoke and the cooling shrinkage rate of the rim are basically the same, and meanwhile the spoke can be thoroughly q
