Rebar shearing device with straightening structure

Abstract

The invention discloses a steel bar shearing device with a straightening structure. The steel bar shearing device includes an electromagnetic tube, a straightening assembly, and a shearing assembly. One end of the straightening assembly is connected to the electromagnetic tube, and the other end of the straightening assembly is connected to the shearing assembly. , the electromagnetic tube performs stress relief on the steel bar, and the straightening component performs straightening on the steel bar. The electromagnetic tube first makes the inner side of the bending part of the steel bar carry electrons through electrostatic induction, and then cuts the magnetic induction line of the steel bar to generate an induced current, heats the bending part of the steel bar, and then reduces the stress of the bending part, and finally through the eddy current effect. The overall heating can further reduce the existence of stress, improve the straightening effect of the straightening components on the steel bars, and prevent the steel bars from bending again under the action of stress after straightening.

Problems solved by technology

[0002] Steel bars are an indispensable basic material in the construction field. After use, steel bars may be deformed, which is not conducive to the reuse of steel bars after recycling.

[0003] The current steel bar straightening mainly uses the steel bar to pass through the high-speed rotating straightening roller, and the steel bar repeatedly rotates and bends in it, thereby eliminating the internal stress in it to achieve the purpose of straightening. However, the steel bar is driven to move during the rotation of the straightening roller. , and straighten the steel bar during the movement of the steel bar. This straightening method belongs to cold deformation. When the deformation of the steel bar is large, there will be a large deformation stress in the deformation area of ​​the steel bar, which will reduce the toughness of the steel bar and reduce the brittleness. becomes higher, making the steel bar very prone to breakage

[0004] Moreover, the straightening roller drives the steel bar to move and exerts pressure on the steel bar during the moving process, so that the bent part of the steel bar is compressed and straightened. The straightening process is a dynamic process. The inside of the straightened steel bar is deformed due to However, there is a certain stress, and the steel bar will be deformed again due to the slow release of the stress in the later use process.
