Problems solved by technology

[0002] The wheels of automobiles are not only directly exposed to the air during daily use, but also often covered with muddy water. Corrosive chemical components may be carried in muddy water, and it is very easy to rust if it is not cleaned frequently
[0005] The above technology still uses physical means to protect the parts of the wheel hub against corrosion and rust, which is not only targeted, but only applicable to the hub bolts, and the anti-corrosion and anti-rust effect is not ideal

Abstract

The invention belongs to the technical field of auto parts, and particularly relates to a manufacturing method of a rustproof alloy wheel hub. The manufacturing method of the rustproof alloy wheel hubcomprises the following steps that A, an aluminum alloy material is heated to a liquid state, zirconium oxide is added into an aluminum alloy solution, and even stirring is conducted; B, a solution obtained in the step A is injected into a wheel hub mold for two passes of cooling, the temperature in the first pass of cooling is 665 DEG C to 670 DEG C, and the temperature in the second pass of cooling is the room temperature; C, a cooling-formed semi-finished wheel hub is separated from the mold, the outer side of the semi-finished wheel hub faces downwards, half immersed in wax film rustproofoil liquid for a period of time and then taken out for still standing; D, the inner side of the semi-finished wheel hub obtained in the step C is sprayed with rustproof liquid; and E, the semi-finished wheel hub obtained in the step D is subjected to overall film coating through activated carbon, and thus a finished wheel hub is obtained. The wheel hub manufactured through the manufacturing method is resistant to the high temperature and corrosion, can resist corrosion of various corrosive substances of gas, liquid and solid, and is not prone to rusting.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a method for manufacturing an antirust alloy wheel hub. Background technique [0002] The wheels of automobiles are not only directly exposed to the air during daily use, but also often covered with muddy water. The muddy water may carry corrosive chemical components, and it is very easy to rust if it is not cleaned frequently. [0003] Existing hubs are usually strengthened and anti-rust for some components in the hub, such as the technical content disclosed in Chinese patent CN207212894U: a kind of anti-corrosion and anti-rust hub bolts, including a hub bolt body, one end of the hub bolt body is provided with a bolt head The other end is provided with a bolt tail, the surface of the bolt head is provided with a hub bolt stainless steel cap, and the bolt head and the hub bolt stainless steel cap are punched and riveted by a punching machine, and the lower edge of the bolt he...
