AI Technical Summary
Existing spiral steel pipe sizing machines cannot adapt to steel pipes of different sizes, resulting in unstable fixing and affecting processing accuracy and efficiency.
The design employs a combination of clamping and fixing mechanisms, including a drive assembly, sliding block, sliding column, rotating column, and clamping ring. Multi-stage transmission is achieved through cylinder and motor drive to adapt to the sizing requirements of steel pipes of different diameters and ensure stable positioning.
It improves the adaptability and stability of steel pipe sizing, reduces vibration and displacement, enhances processing accuracy and efficiency, and extends equipment life.
