Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing and relates to a welding device for circulating water cooling and hydraulically clamping a rim. Background Art

[0002] In the production process of wheel hubs, long iron plates are first cut and rolled into a circle, and then the joints are welded into barrels before the next maintenance process can be carried out. Generally, the inner ring is clamped to make upper and lower pressure blocks with the same inner and outer diameters as the corresponding welding cylinders. After the upper and lower pressure blocks are clamped, the gap is welded. This operation has certain risks and limitations. For example, during the welding process, high temperature and heat will be generated. At the gap of the rim, the heat-affected zone around the weld is large, and the internal crystal structure of the material in this area changes. It becomes more brittle and harder, and the ductility is greatly reduced. When the next process is carried out, it is easy to cause cracks at the rim weld, and the qualified rate is not high. Another point is that, for example, a 16-inch tooling can only weld 16-inch rims. When the product model is switched, the entire pressure block needs to be replaced, which has poor versatility, high cost, long time, and inconvenient operation for employees. At the same time, there is a risk of loosening and not clamping due to heating of the workpiece during welding. Summary of the invention
