AI Technical Summary
During the steel pipe piercing process, the different sizes of the steel pipes can cause shaking or collisions with the gap between the steel pipes and the transport track, resulting in scratches or deformation on the surface of the steel pipes.
An automated piercing furnace was designed. By setting a moving groove and adjusting the moving block and rotating plate structure in the conveyor frame, and using a motor to drive the threaded rod and connecting plate, the furnace can position and limit steel pipes of different sizes, thereby reducing shaking.
This effectively reduces the shaking and collision of steel pipes during transportation, protects the surface of the steel pipes, and ensures the stability of the production process.
