The invention discloses a wheel casing manufacturing process, which belongs to the technical field of wheel casing manufacturing, and comprises the following steps: preparing a plate-shaped metal raw material, stretching the plate-shaped metal raw material, then trimming, pre-trimming a welding part according to the welding side of a wheel casing, and trimming a plurality of plug welding notches in the welding part; then flanging treatment is conducted, and the width of the flanging of the welding part does not exceed the depth of the plug welding notch; functional holes are punched in the front face of the cover body semi-finished product. The invention further discloses a wheel casing. By means of the process method, the plug welding notch can be manufactured in the shield body prefabricated part stage, the design of the plug welding notch is achieved, the adaptability to deformation during plug welding is high, the problem of plug welding spot deformation does not need to be considered any more in the flanging process of a shield body semi-finished product, and the production efficiency is improved. The problem that in the prior art, in order to adapt to plug welding round holes, plug welding spots can only be manufactured through a prefabricated stamping die after the plug welding round holes are formed in place is solved.

    本发明公开了一种车轮轮罩制造工艺,属于车轮轮罩制造技术领域,包括如下步骤:准备板状金属原材料,对板状金属原材料进行拉伸处理,之后进行修边处理,其中,依车轮轮罩的焊接侧预修制焊接部,在焊接部修数个塞焊缺口;之后进行翻边处理,其中,焊接部的翻边的宽度不超过塞焊缺口的深度;对罩体半成品的正面冲制功能孔。还公开了一种车轮轮罩。通过本公开中的工艺方法,使得罩体预制件阶段就可以制作完成塞焊缺口,塞焊缺口的设计,塞焊时对变形的适应能力强,在罩体半成品的翻边工艺时,不需要再考虑塞焊点变形量的问题,改变了现有工艺中为了适应塞焊圆孔必须要在成型到位后使用预制的冲压模具才能进行制造塞焊点的问题。
