Description

Technical Field

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. Rebars are prone to bending during transportation, and need to be corrected in time for normal use. The rebar bending straightener is a device used to bend rebars.

[0003] After searching, the existing Chinese patent with publication number CN202321095927.9 discloses a steel bar correction equipment for construction. A motor is arranged so that the lower conveyor belt and the upper conveyor belt drive the anti-slip steel balls to transport the steel bar body to the correction table in the correction box. A second hydraulic cylinder body is arranged so that each clamping plate clamps and fixes the steel bar body. A telescopic cylinder body is arranged to drive the straightening block to straighten the steel bar body.

[0004] The above technical scheme has the following defects: although such a steel bar bending and straightening machine structure can correct the bent parts of the steel bars through the splint structure, in actual construction, such a steel bar straightening machine structure needs to transport the steel bars to the machine body for correction treatment, and most steel bars are bent only in some parts. It is more laborious to transport them to the straightening machine for treatment and then transport them to the construction site during construction. In order to facilitate the correction of simple bent steel bars in the construction site, a steel bar bending and straightening machine is proposed. The overall volume is small, which is convenient for moving to the construction site to correct the bending of the steel bars. The straightening machine is overall arranged as a splicing structure that is easy to assemble, which is convenient for disassembly and maintenance when damaged, and can be extended as needed. A driving structure is provided to drive the steel bars into the straightening machine, and a staggered correction structure is provided to correct the steel bars in two directions, so that the bent parts of the steel bars can be quickly corrected.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
