[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as in mechanical structural components. Furthermore, it is lighter in weight while maintaining the same bending and torsional strength, making it widely used in the manufacture of mechanical parts and engineering structures. During processing, stainless steel pipes are prone to bending deformation, leading to a decrease in straightness. To ensure the straightness of stainless steel pipes, straightening equipment is needed to improve their straightness.

[0003] Traditionally, the straightening and shaping of stainless steel pipes is done using rigid straightening, which involves using rigid straightening rollers to press against the pipe. If the pipe has a large degree of curvature, rigid straightening can cause significant damage. Therefore, this invention proposes a stainless steel pipe straightening and shaping machine that uses both rigid straightening and repair straightening methods. It employs two different straightening schemes for pipes with large and small degrees of deformation, respectively, which are less likely to cause damage to the pipe surface, are easy to use, and have high processing efficiency.
