Problems solved by technology

[0003] But precisely because of the high aesthetics of the aluminum alloy wheel, people can't tolerate it with a little flaw in appearance, and often replace it with a little scratch or slight deformation
[0004] But everyone knows that the aluminum alloy wheel hub is not only an appearance part for decoration, but also an important part that determines the safe driving of the car. It needs to have enough strength to withstand various loads generated when the car is running. Alloy wheels are also more expensive

Embodiment

[0035] refer to figure 1 , the present invention proposes a kind of automobile aluminum alloy wheel hub remanufacturing process, comprises the following steps:

[0036] S1. Inspection and evaluation: Before remanufacturing the aluminum alloy wheel hub, it must be inspected and evaluated to determine whether the wheel hub has remanufacturing value; it can be divided into the following two situations:

[0037] 1) Damage condition

[0038] Any one of the following conditions shall be judged as having no remanufacturing value.

[0039] Spoke defects of the hub; cracks at the root of the spokes (flaw detection if necessary); the length of a single fracture at the protruding part of the wheel rim exceeds 50MM or more than 3 fractures and each fracture is greater than 20MM; other damages that are difficult to remanufacture.

[0040] 2) degree of deformation

[0041] Any one of the following conditions should also be judged as having no remanufacturing value.

[0042] The overall ...

Abstract

The invention discloses a remanufacturing process of an automobile aluminum alloy hub, which comprises the following steps: S1, detecting and evaluating: determining if the hub has remanufacturing value; S2, distinguishing repair types: comprising two types, wherein one is appearance scratching / discoloring / paint peeling / plating peeling and the other one is deformation or defect; for the aluminum alloy hub subjected to appearance scratching / discoloring / paint peeling, sequentially implementing the following steps of S3-S8; and for the deformed or defective aluminum alloy hub, sequentially implementing the following steps of S9, S10, S11 and S12; S3, performing paint peeling treatment; S4, polishing; S5, spraying baking varnish; S6, performing wire drawing; S7, electroplating (vacuum coating); S8, inspecting finished products: for qualified finished products, putting the products in a storage and delivering the goods, and for unqualified finished products, returning to the preceding steps and performing treatment; S9, performing hydraulic shaping; S10, performing fusion welding and filling; S11, treating the weld-up surface; and S12, performing flaw detection: performing fine correction and finish turning on the aluminum hub subjected to flaw detection and sequentially implementing the steps of S3-S8.

Description

technical field [0001] The invention relates to the technical field of remanufacturing aluminum alloy wheels for automobiles, in particular to a remanufacturing process for aluminum alloy wheels for automobiles. Background technique [0002] Aluminum alloy wheels are more and more used in various automobiles because they have many excellent characteristics compared with steel rims, such as: wheels of the same specification can reduce a lot of weight; they have sufficient strength and are not easy to corrode ; Die-casting molding process is simple, can be designed into any shape to meet people's aesthetic requirements and so on. [0003] But precisely because of the high aesthetics of the aluminum alloy wheel, people can't tolerate it with a little flaw in appearance, and often replace it with a little scratch or slight deformation. [0004] But everyone knows that the aluminum alloy wheel hub is not only an appearance part for decoration, but also an important part that det...
