[0003] When the bending machine is in use, the driving mechanism drives the turntable to rotate, and the turntable drives two bending rods. The steel bar is placed between the two bending rods. When the bending rod rotates with the turntable, the steel bar is bent. In construction projects, steel bars of different diameters are used. When bending steel bars of small diameter, the large spacing between the two bending rods will affect the bending accuracy of the steel bar due to the small diameter of the steel bar. Therefore, the steel bar bending machine in the prior art has poor adaptability and it is difficult to bend steel bars of different diameters while ensuring the bending accuracy. For this reason, an intelligent steel bar bending machine is proposed. Utility model content:
