A support platform 8 is symmetrically welded to the upper end of the fixing plate 21, and the support platform 8 is used to support the metal composite pipe 7. The support platform 8 is located between the two support blocks 4. An arc groove is provided on the upper end of the support platform 8 to facilitate supporting the metal composite pipe 7.

[0026] The adjacent sides of the two support blocks 4 are both rotatably connected with a connection plate 18. The support blocks 4 and the connection plate 18 are both provided with circular through holes, and the through holes on the support blocks 4 correspond to the through holes on the connection plate 18. The metal composite tube 7 is placed in the through hole.

[0027] The clamping assembly is arranged in the through hole of the connecting disk 18, and the clamping mechanism is used to fix the metal composite pipe 7. The clamping assembly includes three rotating wheels 19. Three annular grooves are evenly opened on the connecting disk 18 along the circumferential direction, and a slider 16 is slidably arranged in the annular groove, and the slider 16 is hinged to the connecting plate 12 through an axial rod. A connecting rod 15 is slidably arranged in the slider 16. Three fixed shafts 14 are evenly fixedly connected to the side of the support block 4 close to the connecting disk 18, and the fixed shaft 14 is arranged horizontally. The connecting rod 15 corresponds to the fixed shaft 14 one by one, and one end of the connecting rod 15 is rotatably connected to the corresponding fixed shaft 14. The rotating wheel 19 corresponds to the connecting rod 15 one by one, and the rotating wheel 19 is rotatably installed at the end of the corresponding connecting rod 15 away from the fixed shaft 14.

[0030] A controller is provided on the housing 9, and a plurality of control modules are installed in the controller.

The operation of the welding device is controlled by the controller to realize the integrated design of the welding device. A buzzer is installed on the housing 9, and the buzzer is electrically connected to the controller. When the metal composite component is about to be welded, the buzzer emits a buzzing sound to remind.

[0031] The control module includes a time module, a speed module, etc. The speed module controls the transmission speed during the welding process of different metal composite pipes 7.

When the welding time is over, the controller stops the first motor 5, the second motor 10, the third motor 20 and the cylinder 3, takes out the welded metal composite pipe 7 and the clamping mechanism, and puts the next group of assembled metal composite pipes 7 and the clamping mechanism into the chute 23, saving waiting time and improving production efficiency.

[0032] In summary, a group of assembled metal composite pipes 7 and the clamping mechanism are placed in the slide groove 23 on the bottom plate 1. The position where the metal composite pipe 7 needs to be welded is in the same vertical plane as the axis of the hot-melt butt welding machine 13.

[0033] Start the cylinder 3, which moves the top plate 22 toward the shell 9. The top plate 22 contacts the fixed plate 21 and pushes the clamping mechanism to move as a whole. When the welding point of the metal composite pipe 7 is below the hot-melt butt welding machine 13, the cylinder 3 stops.

[0034] The second motor 10 is started, and the second motor 10 rotates the threaded rod 11, and the threaded rod 11 moves the connecting plate 12 downward, and the connecting plate 12 moves the hot melt butt welding machine 13, and the hot melt butt welding machine 13 is moved to the position where the metal composite pipe 7 is to be welded, and the second motor 10 stops. The hot melt butt welding machine 13 welds the metal composite pipe 7. At the same time, the third motor 20 is started, and the third motor 20 rotates one of the rotating wheels 19, and the rotating wheel 19 rotates the metal composite pipe 7, and the metal composite pipe 7 rotates the other two rotating wheels 19, and the welding of the metal composite pipe 7 is completed.

[0035] During the welding process, the display screen displays the welding time. When the welding time is about to end, the welding countdown starts and the buzzer sounds to remind you. The next group of metal composite pipes 7 is assembled. The metal composite pipe 7 is passed between the three rotating wheels 19 so that the other end of the metal composite pipe 7 is placed on the support platform 8. The ends of the two metal composite pipes 7 that are close to each other are abutted.

[0036] Start the first motor 5, which makes the gear 6 rotate forward, and the gear 6 makes the connecting plate 18 rotate backward through the gear ring 17, and the connecting plate 18 rotates with the slider 16, and the slider 16 makes the connecting rod 15 rotate upward around the axis of the fixed shaft 14, and at the same time, the connecting rod 15 slides relative to the slider 16, and the connecting rod 15 moves the rotating wheel 19 to the center of the metal composite pipe 7 during the rotation process, thereby clamping and fixing the metal composite pipe 7. When the next group of metal composite pipes 7 is assembled, the welding of the metal composite pipes 7 in the process of welding is completed. The three rotating wheels 19 can clamp and fix the metal composite pipes 7 of different sizes.

[0037] After a group of metal composite pipes 7 are welded, the cylinder 3 contracts, the second motor 10 reverses the threaded rod 11, the threaded rod 11 moves the connecting plate 12, and the connecting plate 12 moves the hot melt butt welder 13 away from the metal composite pipe 7. After the hot melt butt welder 13 is away from the metal composite pipe 7, the welded metal composite pipe 7 and the clamping mechanism are quickly removed by the handle 2, and the next group of assembled metal composite pipes 7 and the clamping mechanism are placed in the slide 23. Repeat the above operation to weld the metal composite pipe 7. This saves waiting time and improves production efficiency.

[0038] The welded metal composite pipe 7 is removed. The first motor 5 is reversed, and the first motor 5 causes the gear 6 to reverse, and the gear 6 causes the connecting plate 18 to rotate forward through the gear ring 17, and the connecting plate 18 causes the connecting rod 15 to move away from the center point of the connecting plate 18 through the slider 16. The metal composite pipe 7 can be removed.
