Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a device for removing oxide scale during submerged arc welding of a wheel rim. Background Art

[0002] The rim, commonly known as the wheel ring, is the component on the wheel that mounts and supports the tire around it, and together with the spokes forms the wheel.

[0003] Currently, the spoke and rim synthesis process mostly uses submerged arc welding. For the spoke and rim synthesis welding in all positions, it needs to be heated to a relatively high temperature. However, during the heating process, the rim reacts with the air and forms an oxide scale on the outer surface of the rim weld, which not only affects the appearance quality but also causes a reduction in local strength. Many wheel factories use manual methods to remove the oxide scale, which is time-consuming and labor-intensive. Utility Model Content
