Description

Technical Field

[0001] The utility model relates to the technical field of steel bar straightening equipment, in particular to a steel bar straightening equipment. Background Art

[0002] The steel bar straightening machine is mainly composed of a frame, a bending adjustment device, a straightening roller device, a transmission system and an electrical system. It is driven by a motor and a series of gears and chains are used to send the bent steel bars into the straightening area. After being straightened by multiple straightening rollers, the steel bars are straightened. During the straightening process, the position and pressure of the straightening rollers are controlled by adjusting the device to ensure that the steel bars reach the required straightness.

[0003] At present, the existing steel bar straightening machine cannot grind the rust on the steel bar when straightening the steel bar, and the rusty steel bar will continue to be corroded. Therefore, the Chinese utility model patent disclosed by the existing publication number CN219837103U: Steel Bar Straightening Machine, this application uses an upper guide wheel and a lower guide wheel to ensure the horizontal transportation of the steel bar. After the steel bar enters the drum, the rotation of the drum drives the grinding layer to rotate and then grinds and removes rust on the circumferential surface of the steel bar to prevent the straightened steel bar from being further corroded. However, in this application, the reduction motor is used to cooperate with the gear and the ring gear to rotate the drum, so as to cooperate with the internal grinding component to grind the rust on the outer surface of the steel bar. On the one hand, the grinding mechanism is driven by an additional reduction motor in this application, which increases the energy consumption of the overall equipment. On the other hand, the setting of the sleeve in this application increases the size of the overall equipment structure, which is not conducive to the integration of the equipment. Its large-structure transmission component is also not conducive to improving the convenience of later maintenance. Utility Model Content
