[0002] With the continuous improvement of living standards, the rapid development of the construction industry has promoted the development of its material processing technology. Rebar, as an indispensable material in the construction industry, refers to steel used in reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. In order to facilitate and save transportation space during transportation, the steel bars are often coiled. The coiled steel bars need to be straightened before they can be used as materials for construction projects, so a steel bar straightening machine is used.

[0003] After the existing steel bar straightening machine straightens the steel bar, it needs to cut it into a certain length for use. The existing cutting method is often to manually cut it with pliers, which wastes a lot of manpower and has low work efficiency. Some use machinery for cutting, but the cutting is often not synchronized with the straightening. It is necessary to turn off the power of the straightening machine and then cut the straightened steel bar, which reduces the work efficiency. In addition, the existing steel bar straightening machine can often only straighten steel bars of one diameter, which is very inconvenient to use and has a poor straightening effect.

The support body 21 is the main supporting structure of the entire cutting mechanism, providing a stable foundation and support. The mounting frame 22 carries the cutting machine and fixes it on the support body 21 to support and position the cutting machine to ensure that it remains stable and accurate during operation. An electromagnetic slide 221 is arranged at the inner bottom of the mounting frame 22, and a Sliding plate 222, sliding plate 222 is located at the top of mounting frame 22 and is installed with a cutting machine, electromagnetic slide groove 221 is a device that uses electromagnetic force or electromagnetic drive system to achieve sliding motion, sliding plate 222 can slide along the slide groove at the bottom of the inner side of mounting frame 22 by connecting with electromagnetic slide groove 221, sliding plate 222 is located at the top of mounting frame 22, and carries the cutting machine, so that the cutting machine can move inside mounting frame 22 under the guidance of sliding plate 222, by adjusting the position of sliding plate 222 in electromagnetic slide groove 221, the cutting machine can be accurately positioned on mounting frame 22. The shape of mounting frame 22 is preferably square. The shape of sliding plate 222 is preferably square.

[0034] A hydraulic cylinder is arranged on the top of the sliding plate 222, and a piston rod is movably connected inside the hydraulic cylinder.
