Embodiment 1

[0041] The invention provides a wheel hub color registration method, such as figure 1 shown, including the following steps:

[0042] s1: Spray the first color paint on the shape surface of the wheel hub;

[0043] s2: Spray the second color paint on the modeling surface and cover the first color paint;

[0044] s3: baking treatment;

[0045] s4: The modeling surface includes the removal area, remove the second color paint on the removal area, and expose the first color paint.

[0046] Specifically, when spraying, the color to be retained in the removed area is first defined as the first color paint, and then the entire modeling surface is fully covered with the first color paint. It should be understood that the modeling surface does not necessarily refer to a plane, but broadly refers to all areas that can be displayed for displaying the shape of the wheel hub, such as areas such as hub spokes and window surfaces. Then define the color to be retained outside the removed ar...

Embodiment 2

[0065] A method of manufacturing a hub, such as figure 2 shown, including the following steps:

[0066] a: Using a casting mold to hydraulically cast the wheel hub raw material;

[0067] b: Use a punching machine to perfect the center hole of the bolt hole indexing circle diameter;

[0068] c: heat treatment, and use shot peening equipment to perform shot peening treatment to obtain the primary hub;

[0069] d: Spray primer on the primary hub;

[0070] e: Spray the first color paint on the modeling surface of the primary hub;

[0071] f: After the first color paint is sprayed, cover and spray the second color paint on the first color paint;

[0072] g: The modeling surface includes the surface that can be finished, and the finishing treatment is carried out on the surface that can be finished, and the feed rate of the turning tool is adjusted according to the film thickness of the second color paint to remove the second color paint on the surface that can be finished , a...

Abstract

The invention provides a hub color over-coating method which comprises the steps that (S1) a shaping face of a hub is sprayed and coated with a first color paint; (s2) the shaping face is sprayed andcoated with a second color paint which covers the first color paint; (s3) baking treatment is carried out; and (s4) the shaping face comprises a removal area, the second color paint on the removal area is removed, and the first color paint is exposed. The solution has the beneficial effects that development of a spraying protection tool is omitted; cost is saved; a manufacture cycle is increased;a border line at a border of two colors is distinct; the method is particularly applicable to color over-coating processing of a special car type which has a plane capable of finish turning; and the solution not only can realize color over-coating of an edge plane of the hub, but can also realize color over-coating of a spoke. The invention also provides a manufacture method for the hub.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a wheel hub color registration method and a wheel hub manufacturing method. Background technique [0002] The invention relates to an aluminum wheel hub used for coloring. The wheel hub coloring refers to a wheel hub with two colors on one wheel hub. The most important existing color registration process is to develop spray protectors, and then use spray protectors to spray different colors, but the cost of spray protectors is high and the cycle is long. For wheels of special models and not mass-produced, the development cost is high and it is not suitable for development Spray protective gear. In addition, when using protective gear, cover it first and then spray. Because the structure of the rim is complex, it is not a complete plane, and there is a curved surface structure, which leads to errors in the processing of the protective gear. There will be gaps when it is attached to the...
