It can effectively solve the problems of dissimilar metal connection, avoid melting defects, improve joint strength, and save energy and protect the environment. It is widely used in aerospace, automobile manufacturing, rail transportation, and energy industries. In order to improve the adaptability and welding quality of friction welding and expand its application range, some new friction welding methods have been proposed, such as stir friction welding, laser friction welding, and hybrid welding technology.

[0070] The working process of this magnetic drive friction welding device is as follows:

[0071] The position of the moving part 41 is adjusted by the clamping bolt 46 in the clamping assembly 4, which is used to clamp and fix the second material 8 in a specified position, and then the first material 7 is placed above the second material 8, the magnet fixing assembly 3 is installed above the first material 7, and the L-shaped pressing plate 42 is installed above the fixing member 44.

The reciprocating motion control assembly 5 is arranged on the left and right sides of the bottom plate 11, and an adjustment slot 59 is provided at the installation position to facilitate the adjustment of the position of the reciprocating motion control assembly 5. The pressurization control assembly 2 outputs a continuous and constant electromagnetic force to the first material 7, and the output voltage is changed by adjusting the potentiometer on the pressurization control device 21 to change the magnitude of the electromagnetic force. The reciprocating motion control assemblies 5 on the left and right sides of the bottom plate 11 simultaneously output a sinusoidal waveform voltage, and the initial voltage of the waveform is the same. The voltage waveform needs to differ in radian in phase to achieve alternating peaks of the voltage waveform at both ends, and drive the first material 7 to perform high-frequency reciprocating motion above the second material 8 under the constraint of the L-shaped pressing plate 42. During the welding process, the pressure sensor 58 collects the applied pressure, and the temperature collection system 6 collects the temperature of the side and back of the material respectively, to ensure accurate control of the welding process. The high-frequency reciprocating motion of the first material 7 above the second material 8 generates contact surface friction, which in turn generates heat on the contact surface of the materials and causes plastic deformation. Under the action of the applied pressure, the first material 7 and the second material 8 complete the welding through frictional heat and plastic deformation, and the entire welding process is successfully completed.

[0072] In summary, the present invention is reasonably designed and has the following advantages:

[0073] (1) The present invention adopts an electromagnetic drive method. The reciprocating motion control component 5 generates an electromagnetic force to drive the material to perform high-frequency reciprocating motion. The heat generated by friction causes the surface of the material to reach a sufficient temperature to achieve plastic deformation of the material. During this period, the pressurization control component 2 continuously generates a downward electromagnetic force to compress the material that has undergone plastic deformation on the contact surface, thereby achieving friction welding.

[0074] (2) Traditional friction welding devices rely on mechanical parts for friction welding, so they have high energy consumption, low energy conversion efficiency and high maintenance costs. This device uses a non-contact electromagnetic drive method to improve energy conversion efficiency, reduce maintenance costs, and meet the needs of green manufacturing.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
