Description

Technical Field

[0001] The utility model relates to the technical field of friction stir welding, in particular to a friction stir welding protection component. Background Technique

[0002] Friction stir welding is a solid-state welding technology aimed at achieving material connection through frictional heating and plastic stirring. Friction stir welding is achieved by rapidly rotating and stirring a tool between workpieces, thereby generating frictional heat. This frictional heat raises the surface temperature of the workpiece to a plastic state, promoting the formation of a uniform and firm connection of the workpiece. At the same time, friction stir welding may generate metal burrs during welding, which requires a protection component to protect the equipment and extend its service life.

[0034] Driving assembly, arranged on the inner wall of the fixed frame 8 and cooperating with the heat dissipation assembly;

[0035] Protective assembly, arranged on the outer wall of the heat dissipation cylinder 5.

[0036] Refer to Figure 1 、 Figure 3 and Figure 6 As shown in, the protective assembly includes a sliding seat 20 fixedly connected to the outer wall of the heat dissipation cylinder 5. The inner wall of the sliding seat 20 is slidably connected with a mounting seat 21.

One end of the connecting plate 22 away from the mounting seat 21 is fixedly connected with a protective cover 23. A strong tension spring 24 is fixedly connected between the two groups of connecting plates 22. By sliding the mounting seat 21 into the sliding seat 20, it is convenient to install the protective structure. Then, under the pulling action of the strong tension spring 24, the two side connecting plates 22 are pulled closer to each other, and then the protective covers 23 are pulled closer to each other until they abut and surround the friction stir welding body 1, so as to prevent accidental contact with the friction stir welding body 1 and cause scalding, and at the same time, it can resist flying spurs.

[0037] Refer to Figure 2, the driving component includes a motor 10 fixedly connected to the inner wall of the fixed frame 8.

[0041] Specifically, when the friction stir welding protection component is in operation / use: Firstly, when the friction stir welding body 1 generates high temperature during welding, its heat is transferred to the heat conducting column 4 through the contacting heat conducting plate 2, and then conducted to the heat dissipation plate 6 and dissipated through the heat dissipation holes 7. The heat will converge in the heat dissipation cylinder 5. At this time, the motor 10 is started, and the driving gear 11 is driven to rotate by the output end of the motor 10. Then, the driven gear 12 is engaged and driven to rotate, thereby driving the driving cylinder 14 to rotate. The driving cylinder 14 drives the fan cylinder 16 and the fan blades 17 to rotate, so as to generate air extraction to dissipate the heat inside the heat dissipation cylinder 5. If the angle of the fan blades 17 needs to be adjusted, the cylinder 13 can be started, and the sliding rod 15 is driven to rotate by the output end of the cylinder 13. Then, the guide rod 18 is pulled to move inside the fan cylinder 16, thereby pulling and pushing the pull rod 19 to move, and further pulling the fan blades 17 to rotate inside the fan cylinder 16, so as to achieve angle adjustment. In this way, under the condition of unchanged power, the effective area of the fan blades 17 can be increased, so as to better capture and generate wind power. The fan blades 17 can reduce noise at a certain angle, so as to facilitate providing a comfortable working environment. The protective structure is conveniently installed by sliding the mounting seat 21 into the sliding seat 20. Then, under the pulling action of the strong tension spring 24, the connecting plates 22 on both sides are pulled to approach each other, and further the protective covers 23 are pulled to approach each other until they abut and surround the friction stir welding body 1, thereby preventing accidental contact with the friction stir welding body 1 and causing scalding, and at the same time, it can resist the flying spurs.
