Abstract

The invention discloses a welding method for an inner ring and an outer barrel ring of a two-piece type rim. The welding method comprises the following steps that an aluminum alloy plate is rolled into a hollow cylindrical barrel; welding a cylinder seam formed when the plate is rolled through friction stir welding equipment; the outer surface of the cylinder is subjected to spinning machining, and the specific contour of the rim is machined; processing an inner ring for fixing a spoke by adopting the same material of the barrel in the step A; the inner ring is placed at the designated position in the inner ring of the barrel, a welding head of friction stir welding equipment is moved to the corner of one side of the inner ring in the inner ring of the barrel for welding operation, after the side is welded, the welding head is moved to the corner of the other side for welding operation, and after welding is completed, turning is conducted to polish a welding seam; the two-piece type rim finished product is obtained after heat treatment machining is conducted on the rim. The method has the advantages that the finished product production qualification rate is high, air leakage is avoided, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of hub processing, in particular to a welding method for an inner ring and an outer cylindrical ring of a two-piece wheel rim. Background technique [0002] The two-piece hub includes the spokes and the rim. The spokes of the hub are fixed on the inner ring of the rim by screws. During the processing, the spokes and the rim of the hub are processed separately, and the quality of the two directly determines the quality of the hub. [0003] At present, the rims of two-piece hubs on the market often adopt the process of spinning and friction stir welding, that is, the cylinder of the rim is processed by spinning, and the inner ring is also processed on the other side, and finally it is welded by stirring. The friction welding machine welds the two into a whole, but the processing method currently used is to place the welding head of the friction stir welding on the outer side of the rim cylinder at the contact ...
