Description

Technical Field

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

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. It includes plain round steel bars and ribbed steel bars. Rebars mainly bear tensile stress in concrete. Deformed steel bars have greater bonding ability with concrete due to the effect of the ribs, and thus can better withstand the effects of external forces. Rebars are widely used in various building structures and civil defense door production and other fields.

[0003] By comparing with a rebar straightening machine with patent announcement number CN218192276U, in this scheme, during the long-term storage of the rebar, rust and the like may appear on the surface of the rebar due to the humidity of the environment. This device cannot better process the rust on the surface of the rebar before straightening the rebar. Therefore, during the long-term straightening process of the rebar, the rust on the surface of the rebar may adhere to the straightening roller, which may affect the accuracy of the rebar straightening and reduce the straightening accuracy. There are certain limitations. Utility Model Content
