TECHNICAL FIELD

[0001] The application relates to the technical field of straightening devices, in particular to a reinforcing steel bar straightening device. BACKGROUND

[0002] With the development of society, various high-rise buildings are built in cities, and the construction of city high-rise buildings cannot be separated from reinforcing steel bars. Reinforcing steel bars are widely used. Due to their good ductility, they are suitable for use as the frame of high-rise buildings. The reinforcing steel bars are preferably straight during use. However, the reinforcing steel bars are bent due to their good ductility. These bent reinforcing steel bars can be straightened by a reinforcing steel bar straightening machine for reuse, thereby saving steel resources and reducing construction costs.

[0003] The prior art document with the publication number CN217798655U provides a reinforcing steel bar straightening device. The reinforcing steel bar moves from back to front. The reinforcing steel bar passes between the grooves on the two straightening rollers in the straightening roller group. The two straightening rollers in the same straightening roller group rotate towards each other. The two straightening rollers bite the reinforcing steel bar and drive the reinforcing steel bar to move forward. The grooves on the straightening rollers limit the reinforcing steel bar. The straightening rollers straighten the reinforcing steel bar during rotation. Before straightening, the first straightening plate is closer to the rear straightening roller group. The reinforcing steel bar is bitten by the corresponding straightening roller after passing through the first through hole. Then, the first straightening plate is driven by the second driving assembly to move backward, so that the reinforcing steel bar is pre-straightened by the first straightening plate before being straightened by the straightening roller. The backward movement of the first straightening plate can reduce the bending curvature of the reinforcing steel bar and limit the reinforcing steel bar to reduce the swing curvature of the rear end of the reinforcing steel bar. After the reinforcing steel bar is pre-straightened by the first straightening plate and straightened by the two straightening roller groups, it is discharged from the front side of the front straightening roller group. After the reinforcing steel bar passes through the first through hole on the first straightening plate and is straightened by the straightening roller, the first straightening plate can move forward and backward. The first straightening plate can pre-straighten the reinforcing steel bar. The backward movement of the first straightening plate can reduce the bending curvature of the reinforcing steel bar and limit the reinforcing steel bar to avoid the tail end of the reinforcing steel bar from swinging violently.

[0004] Although the device has many benefits, it still has the following problems: when the reinforcing steel bar is severely deformed at one end or in the middle, the deformed part of the reinforcing steel bar is easily scraped against the first straightening plate during the straightening process, thereby shortening the service life of the first straightening plate. In view of this, we propose a reinforcing steel bar straightening device. Practical new type content
