Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a friction welding device. Background Art

[0002] Friction welding, as a solid-state welding technology, offers advantages such as high weld quality, excellent joint strength, and low process costs, as it avoids material melting and metallographic structural changes during the welding process. It is widely used in a variety of fields, including aerospace, automotive manufacturing, and rail transportation. Friction welding achieves this by rotating the parts to be welded at high speeds relative to each other under axial pressure, using frictional heat to bring the contact surfaces to a plastic state. However, conventional friction welding devices still face some technical challenges in practical applications.

[0003] For workpieces of different sizes or shapes, traditional equipment often requires frequent adjustments to equipment parameters or tool changes, which is not only time-consuming and labor-intensive, but also difficult to guarantee welding accuracy after each adjustment. The high temperatures and metal spatter generated during friction welding can easily pose a safety hazard to operators. Especially without proper protection, operators face a higher risk of work-related injuries. Burrs or protrusions are usually left after welding, which require additional steps to remove, increasing production costs and time. Traditional equipment is often designed for workpieces of specific specifications. When it is necessary to process workpieces of different sizes or materials, the adaptability and flexibility of the equipment are limited.
