Description

Technical Field

[0001] The utility model relates to the field of wheel rim processing, in particular to a device for stirring friction welding of arc-shaped welding surfaces of wheel rims. Background Art

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Modern welding technology is widely used. Among them, the connection between the rim and the spoke of agricultural and forestry wheels, engineering wheels, automobile wheels and tractor wheels is mostly welded. Pressing devices and welding devices are used in the production process. The main production processes of the rim are rounding, butt welding, scraping, flaring, rolling, expansion, and punching valve holes. After the plate is rolled by a rolling machine, it is flattened by a flattening machine before stir friction welding. After stir friction welding, the cylindrical area that was flattened by the flattening machine oil press before stir friction welding needs to be re-rounded in the later production process.

[0003] Existing friction welding has the following disadvantages:

[0004] 1. The production process is complicated, which affects production efficiency. The plate needs to be flattened after rolling, and needs to be re-rounded after stir friction welding. 2. The workload of employees is relatively high, and materials need to be moved back and forth before and after stir friction welding. 3. It affects material properties, because flattening and re-rounding both use gravity oil pressure, which has a certain impact on material properties. Utility Model Content
