Description

Technical Field

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

[0002] Speakers generally refer to modern electroacoustic components, which convert electrical signals into sound. The iron ring is the key component of the speaker's sound. Existing speaker iron rings need to be friction welded during production;

[0003] Friction welding refers to a method that uses the friction heat generated by the friction between thermoplastics to melt the friction surfaces. After pressurization and cooling, they can be connected together. The welding efficiency is 30-70%. Generally, the higher the dynamic friction coefficient, the higher the efficiency. A certain axial pressure is applied to the welding end faces of the two welds, and the contact surfaces are subjected to intense friction motion. The heat generated by friction heats the contact surfaces to a certain welding temperature, and the motion is rapidly stopped. A certain amount of forging pressure is applied to cause a certain amount of plastic deformation of the two weld metals, thereby firmly welding the two welds together. In the process of friction welding, a friction welding device is usually used.

Therefore, it is particularly important to improve the existing friction welding device and design a new friction welding device to change the above technical defects and improve the practicality of the overall friction welding device.
