Description

Technical Field

[0001] The utility model relates to the technical field of pipe welding machines, in particular to high-frequency pipe welding equipment. Background Art

[0002] High-frequency pipe welding machine is a kind of equipment used for welding metal pipes. With the development of science and technology, pipe welding machines are used more and more widely in the industrial field, covering many fields such as construction, petroleum, chemical industry, aerospace, etc. Through a press or a straight-seam welded steel pipe mechanism, the steel strip or steel plate is transported from the steel plant to the straight-seam welded round steel pipe, and then welded by double-welding or submerged arc welding. The welded pipes manufactured by this method can be called straight-seam welded steel pipes. Compared with seamless pipes, straight-seam welded pipes have low cost, high production efficiency, and a wider range of processable sizes and thicknesses. The blanks used are mainly steel plates. Straight-seam welded pipes have strong corrosion resistance in acidic environments.

[0003] For example, a high-frequency pipe welding device is recorded in the patent with patent announcement number CN218109731 U. The solution recorded therein is: through the design of the carrier, dust filter box, purification fan and filter screen, the smoke generated by the straight seam pipe welding machine during operation can be adsorbed and collected, thereby avoiding the smoke from damaging the surrounding working environment and ensuring the health of surrounding workers.

[0004] In the above case, the welding machine cannot be moved. When people weld the pipe, they need to move the pipe so that the pipe seam can be welded into a straight line. At the same time, people cannot position the pipe before welding. They need to manually align the pipe seam with the welding point of the welding machine before welding. However, manually locating the welding point may easily cause welding misalignment or unsightly welding.

[0005] Based on this, a high-frequency pipe welding device is now provided to eliminate the disadvantages of the existing devices. Utility Model Content
