Description

Technical Field

[0001] The utility model relates to a straightening machine, in particular to a steel plate straightening machine, belonging to the technical field of steel plate processing. Background Art

[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wires, etc. A straightening machine uses straightening rollers to squeeze the material to change its straightness. H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings, and light structural weight. It is mainly used for beam and column components in industrial and civil structures. The H-shaped steel includes a vertical plate, an upper horizontal plate, and a lower horizontal plate. The upper and lower horizontal plates are connected to the vertical plate by welding. The welding process will cause the upper and lower horizontal plates to bend, so a straightening machine is needed to straighten the H-shaped steel so that the upper and lower horizontal plates meet production requirements;
