The high-frequency heating component 12 heats and welds the tube material. At the same time, according to the height at which the tube material is placed, the first motor 220, the cylinder 410, and the grinding machine 26 are started. The first motor 220 drives one of the lead screws 22 to rotate. One of the lead screws 22 drives the other lead screw 22 to rotate through the belt 210.

One of the double-headed screws 53 is coaxially and fixedly installed with the driving end of the second motor 530; before grinding the welded pipe, start the second motor 530. The second motor 530 drives one of the double-headed screws 53 to rotate. One of the double-headed screws 53 drives the other double-headed screw 53 to rotate through the obliquely arranged gear 510 and the connecting rod 520. During the rotation of the double-headed screw 53, the moving blocks 54 are driven to move towards each other. The moving blocks 54 drive the moving plates 55 to move towards each other. The moving plates 55 drive the positioning assemblies 56 to move towards each other. When the positioning wheels in the positioning assemblies 56 are in close contact with the weld, turn off the second motor 530. During the movement of the weld, the positioning wheels rotate.

[0030] Working principle: First, place the tube blank formed by extrusion bending rolling into the transmission roller 11 and transmit it towards the high-frequency heating component 12. The high-frequency heating component 12 heats and welds the tube blank. At the same time, according to the height of the placed tube blank, start the first motor 220, the cylinder 410, and the grinding machine 26. The first motor 220 drives one of the lead screws 22 to rotate. One of the lead screws 22 drives the other lead screw 22 to rotate through the belt 210. During the rotation of the lead screw 22, it drives the lifting block 23 to move downward. The lifting block 23 drives the driving block 24 to move downward. The driving block 24 drives the lifting plate 25 to move downward. The lifting plate 25 drives the grinding machine 26 to move downward. When the grinding wheel of the grinding machine 26 is in close contact with the welded part of the welded pipe, turn off the first motor 220. The cylinder 410 drives the driving rod 420 to move upward. The driving rod 420 drives the driving plate 4 to move upward. The driving plate 4 drives the lifting rod 41 to move upward. The lifting rod 41 drives the placing plate 42 to move upward. When the placing plate 42 moves upward to contact the welded pipe after welding is completed, turn off the cylinder 410. At this time, the grinding wheel of the grinding machine 26 grinds the burrs at the welded part of the welded pipe transmitted by the transmission roller 11. By setting the lead screw 22, the lifting block 23, the driving block 24, the lifting plate 25, the grinding machine 26, the driving plate 4, the lifting rod 41, and the placing plate 42, the effect of quickly grinding the burrs at the welded part of the welded pipe is achieved. When working on the welded pipe, the welded pipe after welding can be ground immediately, avoiding subsequent workers from grinding the burrs on the weld. This not only reduces the workload of the workers but also improves the processing efficiency of the welded pipe;

[0031] Subsequently, before grinding the welded pipe, start the second motor 530. The second motor 530 drives one of the double-headed screws 53 to rotate. One of the double-headed screws 53 drives the other double-headed screw 53 to rotate through the bevel gear 510 and the connecting rod 520. During the rotation of the double-headed screw 53, it drives the moving block 54 to move towards each other. The moving block 54 drives the moving plate 55 to move towards each other. The moving plate 55 drives the positioning component 56 to move towards each other. When the positioning wheel in the positioning component 56 is in close contact with the weld, turn off the second motor 530. During the movement of the weld, the positioning wheel rotates. By setting the double-headed screw 53, the moving block 54, the moving plate 55, and the positioning component 56, the effect of fixing the weld is achieved. When grinding the weld, it prevents the welded pipe from moving, improves the grinding quality of the welded pipe, and facilitates the use of the workers.
