Description

Technical Field

[0001] The utility model relates to the technical field of steel bending machines, in particular to a clamping mechanism for steel bending machines. Background Art

[0002] Steel processing is the process of changing the shape of steel. Most steel processing is done by pressure processing, which causes plastic deformation of the processed steel. Sometimes the steel is bent during processing. During the bending process, the width and thickness of the steel will affect the clamping and fixing of the steel, resulting in problems in the bending of the steel. For example, a Chinese patent for a bending device for construction steel, patent number (CN217343345U), effectively avoids the inability of the right clamp and the left clamp to effectively clamp the steel bar when the outer wall diameter of the steel bar to be bent is large through the setting of a locking structure, etc. However, when bending tubular steel, one end is fixed and the other end rotates the bending piece to bend, and flat deformation is prone to occur at the bending point, resulting in the scrapping of the tubular steel and making it unusable.
