High-frequency welded tubes production line is an industrial equipment that uses high-frequency welding technology to produce metal tubes. The production line welds metal strips into tubes through the resistance heat generated by high-frequency current.
Technical principle
The high-frequency welded tubes production line uses the skin effect and proximity effect of high-frequency current to instantly heat the edge of the metal strip to a molten state, and pressurizes the squeeze roller to form a weld
Flying shear control system
As a key component of the production line, the flying shear control system uses advanced motion control algorithms to achieve dynamic shearing (as of 2015, relevant research has achieved phased results). The system can synchronously track high-speed running welded pipes, complete fixed-length cutting and smooth incisions, and effectively reduce material loss
Process flow
1. The metal strip is continuously bent into a tube through the forming unit
2. The high-frequency welding device heats the edge of the pipe seam and pressurizes it
3. The sizing unit adjusts the outer diameter and roundness of the pipe
4. The flying shear system accurately cuts according to the preset length
