Manufacturing method of long-service-life forged aluminum alloy wheel

TLDR: In this article, the surface of the wheel is strengthened by adding a wheel surface treatment process so as to obtain a forged aluminum alloy wheel with long service life, wear resistance, corrosion resistance and oxidation resistance.

Abstract: The invention relates to the technical field of aluminum alloy wheels, and particularly relates to a manufacturing method of a long-service-life forged aluminum alloy wheel The manufacturing method is characterized in that the surface of the wheel is strengthened by adding a wheel surface treatment process so as to obtain a forged aluminum alloy wheel with long service life, wear resistance, corrosion resistance and oxidation resistance The manufacturing method comprises the operation steps of S1, bar heating; S2, forging, specifically, conducting single-step forging on the heated bar; S3, punching and flaring, specifically, expanding rim legs by a certain angle, and punching the center of a forging stock at the same time; S4, cleaning and cooling, specifically, putting the forging stockinto a cleaning line for cleaning; S5, spinning, specifically, placing the forging stock on a spinning lower die for compaction; S6, heat treatment, specifically, conducting heat treatment by means of solid solution, quenching and artificial aging; S7, rough turning; S8, surface roller burnishing, specifically, conducting full roller burnishing on the front surface, a back cavity and an outer side rim of the wheel; S9, drilling and window milling; S10, surface wiredrawing, specifically, conducting wiredrawing treatment is conducted on the front surface and the back cavity of the wheel; and S11, surface passivation, specifically, putting the wheel into a passivation solution for soaking, washing with pure water after passivation and then drying
