And when the sliding rod 12 moves, it can also drive the side connecting rod 10 to move horizontally. The side connecting rod 10 drives the two strip-shaped support plates 8 to move horizontally, and then drives the first gear 7 and the second gear 36 to move above the two processing pipes 5. At this time, start the second servo motor 45. The output shaft of the second servo motor 45 drives the fourth gear 47 to rotate. The fourth gear 47 drives the second gear 36 to rotate.

On one side of the fixed plate 31, there is a multi-stage electric push rod 48 fixedly connected. The piston rod of the multi-stage electric push rod 48 is fixedly connected with one side of one of the sliding rods 12. When the multi-stage electric push rod 48 is started, the piston rod of the multi-stage electric push rod 48 retracts, thereby driving the sliding rod 12 to move horizontally. The sliding rod 12 drives the extension rod 14 to move horizontally. One end of the extension rod 14 contacts the plane of the sliding trapezoidal block 40. At this time, the extension rod 14 pushes the sliding trapezoidal block 40 to drive the side box 15 to move horizontally. The side box 15 drives the rectangular vertical plate 37 to move horizontally. The rectangular vertical plate 37 can drive the two cutting discs 11 to move between the two processing pipes 5.

[0044] Particularly, first chutes 13 are formed in the tops of the processing tables 1. A same bidirectional lead screw 35 is rotatably connected between the inner walls on both sides of the first chute 13. Two symmetrically arranged second sliders 34 are slidably connected between the inner walls on both sides of the first chute 13. The bidirectional lead screw 35 threadedly penetrates through the two second sliders 34. The tops of the second sliders 34 are fixedly connected to the bottoms of the corresponding first support plates 4. A first servo motor 3 is fixedly connected to one side of the processing table 1. The output shaft of the first servo motor 3 rotatably penetrates into the first chute 13 and is fixedly connected to one end of the bidirectional lead screw 35. At this time, the two processing pipes 5 are pushed to approach each other. The specific operation is to start the first servo motor 3. The output shaft of the first servo motor 3 drives the bidirectional lead screw 35 to rotate. The bidirectional lead screw 35 drives the two second sliders 34 to approach each other. The two second sliders 34 drive the two extension rods 14 to approach each other. The two extension rods 14 drive the side clamping blocks 2 and the sliding seats 18 to approach each other. The two side clamping blocks 2 can push the two processing pipes 5 to approach each other. One ends of the two processing pipes 5 are abutted against one side of the cutting disc 11.

[0045] Particularly, an extension rod 14 is fixedly connected to one side of one of the sliding rods 12. A side box 15 is fixedly connected to one side of the rectangular vertical plate 37.

At this time, the extension rod 14 pushes the sliding trapezoidal block 40 to continue to move. After the inclined surface of the sliding trapezoidal block 40 contacts the inclined surface of the fixed trapezoidal block 33, the sliding trapezoidal block 40 retracts into the strip-shaped groove 42 and compresses the spring 41. At this time, the sliding trapezoidal block 40 is disengaged from the extension rod 14. The rectangular vertical plate 37 is reset under the action of the compression spring in the second chute 32. At this time, the cutting disc 11 moves to the initial position.

[0046] A method for welding and forming a ventilation duct specifically includes the following steps;

[0048] S2. Move the cutting component between the two processing pipes 5 and cut the end faces of the two processing pipes 5;

[0049] S3. Move the power component above the two processing pipes 5 to provide power for the cutting component;

[0050] S4. Move the cutting assembly out, bring the two processing pipes 5 close to each other and press them tightly.

[0051] S5. The power assembly provides power for the two clamping assemblies and cooperates with the welding device to complete the welding operation.

[0052] S6. Loosen one side of the support assembly, which can help the processed pipe 5 after welding to be discharged, realizing the blanking operation.

[0053] Working principle: When processing the processing pipe 5 is required, first place the two processing pipes 5 above the fixed arc block 22 and the rotating arc block 23, and multiple fixed support seats 17 can temporarily support the processing pipe 5 to ensure the stability of the processing pipe 5. The side connecting rod 10 and the cutting disc 11 are both located on one side of the device, which can facilitate the hoisting of the processing pipe 5 from above and quickly complete the feeding operation.

[0054] Start the multi-stage electric push rod 48. The piston rod of the multi-stage electric push rod 48 retracts, thereby driving the sliding rod 12 to move horizontally. The sliding rod 12 drives the extension rod 14 to move horizontally. One end of the extension rod 14 contacts the plane of the sliding trapezoidal block 40. At this time, the extension rod 14 pushes the sliding trapezoidal block 40 to drive the side box 15 to move horizontally. The side box 15 drives the rectangular vertical plate 37 to move horizontally. The rectangular vertical plate 37 can drive the two cutting discs 11 to move between the two processing pipes 5.

[0055] At this time, push the two processing pipes 5 and make them close to each other. The specific operation is to start the first servo motor 3. The output shaft of the first servo motor 3 drives the bidirectional lead screw 35 to rotate. The bidirectional lead screw 35 drives the two second sliders 34 to approach each other. The two second sliders 34 drive the two extension rods 14 to approach each other. The two extension rods 14 drive the side clamping blocks 2 and the sliding seats 18 to approach each other. The two side clamping blocks 2 can push the two processing pipes 5 to approach each other. One end of the two processing pipes 5 abuts against one side of the cutting disc 11.

[0056] And when the sliding rod 12 moves, it can also drive the side connecting rod 10 to move horizontally. The side connecting rod 10 drives the two strip-shaped support plates 8 to move horizontally, thereby driving the first gear 7 and the second gear 36 to move above the two processing pipes 5. At this time, start the second servo motor 45. The output shaft of the second servo motor 45 drives the fourth gear 47 to rotate. The fourth gear 47 drives the second gear 36 to rotate. The second gear 36 drives the third gear 44 to rotate. The third gear 44 drives the rotating connection cylinder 43 to rotate. The rotating connection cylinder 43 drives the two cutting discs 11 to rotate. The two cutting discs 11 drive the cutting knives 39 to rotate, thereby realizing the cutting operation on one end of the processing pipe 5.

[0057] After cutting is completed, start the multi-stage electric push rod 48 again, so that the piston rod of the multi-stage electric push rod 48 continues to retract. At this time, the extension rod 14 pushes the sliding trapezoidal block 40 to continue moving. After the inclined surface of the sliding trapezoidal block 40 contacts the inclined surface of the fixed trapezoidal block 33, the sliding trapezoidal block 40 retracts into the inside of the strip-shaped groove 42 and compresses the spring 41. At this time, the sliding trapezoidal block 40 is disengaged from the extension rod 14, and the rectangular vertical plate 37 is reset under the action of the compression spring in the second chute 32. At this time, the cutting disc 11 moves to the initial position;

[0058] Continue to start the first servo motor 3 so that the two processing pipes 5 are completely in contact, and the sliding seat 18 passes through the two fixed support seats 17. At this time, the two processing pipes 5 are only supported by the fixed arc block 22 and the rotating arc block 23. The second servo motor 45 can be started, and the rotation of the rotating shaft 9 drives the two first gears 7 to rotate. The two first gears 7 drive the toothed ring 19 to rotate. The toothed ring 19 drives the side clamping block 2 to rotate. The side clamping block 2 drives the processing pipe 5 to rotate. Workers only need to stand on one side, and then they can cooperate with the welding device to complete the welding operation;

[0059] After the welding operation is completed, start the first servo motor 3 at this time, so that the two first support plates 4 move away from each other. The welded processing pipe 5 remains on the tops of the two groups of fixed arc blocks 22 and rotating arc blocks 23. The first support plate 4 drives the sliding seat 18 to move horizontally through the arc connecting rod 21. The sliding seat 18 drives the connecting plate 16 and the triangular inclined block 6 to move horizontally. The triangular inclined block 6 moves out from under the sliding cushion plate 24. At this time, the sliding cushion plate 24 moves downward under the pulling force of the tension spring 30, and the rotating arc block 23 starts to flip around the rotating rod 28. Furthermore, the welded processing pipe 5 above the fixed arc block 22 and the rotating arc block 23 can slide down along one side, completing the discharging process and facilitating the next use.
