AI Technical Summary
During the steel pipe grinding process, the steel pipe is prone to moving due to the high-speed rotation of the grinding machine, resulting in uneven grinding and an uneven surface.
The first motor is started clockwise to drive the bidirectional threaded rod to rotate. The spring force is used to fix the steel pipe in the horizontal and vertical directions. Combined with the flipping mechanism, the steel pipe is rotated to ensure that the steel pipe does not move during the grinding process.
This effectively prevents the steel pipe from moving laterally and longitudinally during the grinding process, improving the uniformity and efficiency of grinding.

[0002] Steel pipe drawing is an important process in steel pipe production, mainly used for manufacturing high precision, small size steel pipe. In cold-drawing steel pipe, burr may occur due to friction and tension on the outer wall. Burr is a common phenomenon in steel pipe production. If not removed, it will affect the appearance, dimensional accuracy of the steel pipe, and even affect the subsequent processing technology (such as welding, painting, etc.).
[0003] During steel pipe processing, burrs on the steel pipe are often removed by mechanical polishing, grinding wheel, sandblasting and other methods to ensure the surface of the steel pipe is smooth and neat. However, when using a polisher to polish the steel pipe, the polishing disc on the polisher rotates at a high speed, which may cause the steel pipe to move during polishing, resulting in uneven polishing and uneven surface.
