company news about What are the steps in a long-life forging process for aluminum alloy wheels?

The invention relates to a method for manufacturing a long-life forging aluminum alloy wheel, in which the surface of the wheel is strengthened by adding a surface treatment process for the wheel, thereby obtaining a long-life, wear resistance, corrosion resistance and oxidation resistance forging aluminum alloy wheel; It includes the following steps: S1: Heating the Bar; S2: Forging: forging the heated bar in one step; S3: Piercing and expanding: Expanding the rim leg at a certain angle, and piercing the center part of the forging stock; S4: CLEANING AND COOLING: Forging stock entering the cleaning line for cleaning; S5: Spinning: pressing the forging blank on the spinning die; S6: Heat Treatment: Heat Treatment: solid solution + quenching + artificial aging; S7: Rough Turning; S8: Surface Rolling: full rolling of the Front, back and outer wheels of the wheel; S9: drilling the Milling Window of the RIM; S10: Surface Drawing: the Front of the wheel and back cavity for drawing treatment; S11: Surface passivation: the wheel into passivation liquid immersion, passivation after washing and drying.
