Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a steel bar bending device for road and bridge construction. Background Art

[0002] Steel bars are common building materials in construction. During the construction process, according to construction needs, it is often necessary to bend the steel bars at a certain angle. In the prior art, steel bar bending is mostly done manually, which is difficult and inefficient. Especially when a large number of steel bar bending operations are required, the use of the steel bar bending device in the prior art will make this work consume a lot of manpower and time costs.

[0003] Publication No. CN212191012U discloses a steel bar bending device. After the matching mandrel and guide block are assembled according to the steel bar size, the two guide blocks are moved to the outside of the mandrel extension line, and then the steel bar to be bent is placed in the two positioning grooves, and the plug plate is inserted. Then, the telescopic rod of the cylinder is controlled to extend and retract according to the calculated distance. During the extension and retraction process of the telescopic rod, its end abuts against the steel bar and pushes the steel bar to gradually bend it. The guide block rotates with the deformation of the steel bar, and the steel bar slides in the positioning groove, so that the bending angle of the steel bar is gradually reduced until the required steel bar bending angle is obtained. After the bending work is completed, the mandrel is retreated, the plug plate is pulled out, and the steel bar is taken out. However, the patent still has the following problems in actual use:

[0004] After assembling the matching push rod and guide block according to the size of the steel bar, move the two guide blocks to the outside of the extension line of the push rod, then put the steel bar to be bent into the two positioning grooves, insert the plug plate, and then control the extension and retraction of the cylinder telescopic rod according to the calculated distance. During the extension and retraction of the telescopic rod, its end abuts against the steel bar and pushes the steel bar to gradually bend it. The guide block rotates as the steel bar is deformed, and the steel bar slides in the positioning groove, so that the bending angle of the steel bar is gradually reduced until the required bending angle of the steel bar is obtained. After the bending work is completed, the push rod is retreated, the plug plate is pulled out, and the steel bar is taken out. However, the above device has a U-shaped bending arc for the steel bar, and when the steel bar needs to be bent, it is more troublesome when it needs to be bent into a larger arc, thereby reducing the bending efficiency of the steel bar.
