Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, specifically a straightening device for small-diameter thick-walled seamless steel pipes. Background Technology

[0002] Seamless steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel materials such as round bars, steel pipes are lighter in weight while maintaining the same bending and torsional strength, making them an economical cross-section steel material. They are widely used in the manufacture of structural components and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in construction. Using steel pipes to manufacture ring-shaped parts can improve material utilization, simplify manufacturing processes, and save materials and processing time, and is now widely used in manufacturing. Small-diameter, thick-walled seamless steel pipes are prone to bending deformation due to mechanical stress during processing, transportation, or storage.

[0003] Traditional steel pipe straightening devices need to be moved constantly according to the position of the bent steel pipe. Frequent changes in the position of the steel pipe increase the operation time, reduce the efficiency of the operation, and increase the labor cost. Utility Model Content
