Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a rust removal component for a steel bar straightening machine. Background Art

[0002] Steel bars are commonly used parts in construction projects and play a very important role in the process of urban construction. When steel bars are not protected and are exposed to humid air for a long time, they will rust. Steel bar corrosion will reduce the bearing capacity of the components and deteriorate the performance of the structure.

[0003] An existing steel bar straightening machine rust removal component (publication number: CN220944685U) has at least the following disadvantages: the above-mentioned device is provided with a grinding block, and the steel bar is rotated and transported to the grinding block after being straightened by the straightening mechanism, and the grinding block grinds and removes rust on the steel bar. However, since the grinding block itself cannot rotate, the steel bar can only rely on the rotation of the steel bar itself to produce friction with the grinding block, so that the rust on the steel bar can be ground off. Therefore, the grinding effect still has room for improvement. At the same time, the rust after grinding cannot be removed in a centralized manner, so that the rust is easily accumulated in the device, which affects the grinding work. For this reason, the utility model is proposed. Utility Model Content

The second motor is then used to drive the grinding roller to rotate, and the rotation direction is opposite to the moving direction of the steel bar, so that the grinding roller and the steel bar are in contact with each other. Bidirectional friction is achieved, thereby better removing rust from the outer surface of the steel bar. By setting a discharge hole, after the rust iron is ground out by the grinding roller, the rust iron can be discharged from the equipment through the discharge hole, effectively preventing the accumulation of rust iron from affecting the processing of the steel bar.
