Technical Field

[0001] The utility model belongs to the technical field of welding tooling, and in particular relates to a moving disc welding tooling. Background Art

[0002] Polyester disc reactors are commonly used in chemical production. The rotor disc, a key component, has a manufacturing precision that directly impacts the reactor's operating efficiency and lifespan. The rotor disc consists of a central hub and multiple layers of agitating blades. Each layer of agitating blades consists of several spokes distributed in an annular pattern around the hub. The inner ends of the spokes are welded to the hub, and the outer ends of the spokes are welded to the annular blades.

[0003] In the traditional manufacturing process of the rotor disc, the assembly and leveling of the hub and spokes is cumbersome, and since the spokes are easily thermally deformed during welding, the flatness of the rotor disc does not meet the standards and needs to be corrected, which not only increases production costs but also prolongs the production cycle.
