[0030] Before chamfer welding the tubular metal, place it inside the ring structure 403. Before placing it, start the sixth electric push rod 422 to push the first electromagnetic block 423 to make a magnetic connection with the second electromagnetic block 424. Subsequently, start the sixth electric push rod 422 to drive the liquid storage tank structure 418 to move towards the mounting plate 414, so that several groups of liquid storage tank structures 418 are located inside the tubular metal. During its movement, it drives the sliding tube 417 to squeeze the compression spring 416, and then disengages from the magnetic connection state between the first electromagnetic block 423 and the second electromagnetic block 424. When several groups of compression springs 416 sense the disappearance of pressure, they drive several groups of first extrusion head structures 420 to abut against the inner wall of the tubular metal. Subsequently, start the air pump 405 to fill the inflatable bag structure 404, so that the inflatable bag structure 404 expands to wrap and limit the outer wall of the tubular metal.

Subsequently, start the sixth electric push rod 422 to push the first electromagnetic block 423 to make a magnetic connection with the second electromagnetic block 424. Then start the sixth electric push rod 422 to drive several groups of second extrusion head structures 421 to move directly above the port. Start the seventh motor 410 to drive the transmission block 411 to rotate. While the transmission block 411 rotates, it drives the third disc 413 to rotate. Subsequently, rust removal work is carried out by squeezing the second extrusion head structures 421, and the position can be assisted and adjusted by the third electric slide 412, improving the port cleaning effect and the pre-treatment effect of the device.

[0032] Drive several groups of extrusion head structures to rust-remove the inner wall of the metal equally and evenly. When there are flanges and multi-layer metal sheets on the inner wall of the metal, it will cause several groups of liquid storage tank structures 418 to start squeezing the compression spring 416. The compression spring 416 acts on the pressure sensor with the reaction force, and then processes the flanges and multi-layer metal sheets at the metal port to improve the subsequent working effect of chamfer welding. And during the subsequent welding process, the distance sensor 419 is used to determine the distance between the two groups of metals. When the welding positions of the two groups of metals are offset, the value of one of the distance sensors will change, improving the accuracy monitoring effect of welding and the working effect of chamfer welding at the same time.

[0033] The metal port is in an inclined state. Before welding, clean it first. Start the fifth electric push rod 406 to drive the third disc 413 to move directly above the metal port. Then start the sixth electric push rod 422 to drive the first electromagnetic block 423 and the second electromagnetic block 424 to be magnetically connected. Then start the sixth electric push rod 422 to drive several groups of second extrusion head structures 421 to move directly above the port. Start the seventh motor 410 to drive the transmission block 411 to rotate. While the transmission block 411 rotates, it drives the third disc 413 to rotate. Then rust-remove by squeezing the second extrusion head structure 421, and the position can be assisted and adjusted by the third electric slide 412, improving the port cleaning effect and the pre-treatment effect of the device at the same time.

[0034] Place the processed tubular metal between two groups of arc-shaped clamping blocks 212. Then start the second motor 210 to drive the threaded rod 206 to rotate. While the threaded rod 206 rotates, it drives two groups of sliding blocks 208 to slide in the sliding cavity 207, thus driving two groups of arc-shaped clamping blocks 212 to clamp the metal. Then during the welding of the two groups of metals, the first electric slide 201 can be started to move parallel, and the first electric push rod 202 can be started to adjust the height, improving the clamping effect and the convenience of position adjustment at the same time.

[0035] Start the second electric slide 302 to adjust the welding parallel.

While the transmission plate 306 rotates, it drives the welding structure 308 to perform angle adjustment welding; start the air pump 405 to fill the inflatable bag structure 404, so that the inflatable bag structure 404 expands and wraps and limits the outer wall of the tubular metal, driving the grinding structure to rub the outer wall of the metal, improving the cleaning effect of the outer wall of the metal. Start the seventh electric push rod 425 to push the elastic scraper 426 to remove the impurities on the inner wall, expanding the working range of the structure.
