[0002] As a bar-shaped steel material with a specific cross-sectional shape, steel sections occupy an important position in industrial production. After a series of processing steps such as drawing and cutting, their cross-sectional shape can basically meet product requirements. However, due to various factors, their straightness often deviates. To ensure the quality of steel sections and meet the needs of subsequent processing and use, they need to be inspected and effectively straightened with the help of straightening machines.

Therefore, during inspection, part of the steel sections will be suspended outside the inspection table. This part of the steel sections will bend under the action of gravity. The bending will directly affect the straightening part of the steel sections, resulting in large straightening errors and affecting the inspection and straightening quality.
