[0002] Rebar is a commonly used basic material on construction sites and an extremely important basic construction tool. It is often used to fix buildings. When produced, the length of the rebar is long and it is difficult to adapt to all construction sites. Therefore, it is sometimes necessary to cut the rebar to make it adapt to different construction sites. The existing equidistant cutting machine for construction rebars generally cuts the rebars with a cutting knife. During the cutting process, the rebars need to be pushed manually, and it is difficult to fix the rebars and calculate the length of the rebar cuts. In addition, the existing cutting method uses the rotary motion of a circular saw blade for cutting. The cutting work takes a long time and the pause interval is long, which further reduces the work efficiency. In view of this, research and improvement are carried out on the existing problems, and a fixed-distance rebar cutting machine is provided to solve the current problems. The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Utility Model Content

[0025] In this embodiment, there are two conveying wheels 430 , guide wheels 210 and crank wheels 350 , which are arranged symmetrically about the center line of the surface of the feeding platform 200 , and the conveying wheels 430 , guide wheels 210 and crank wheels 350 are located in the same horizontal plane.

[0026] In this embodiment, the bottom ends of the second shaft 420 and the first shaft 320 are respectively fixedly sleeved with a second synchronization tooth 421 and a first synchronization tooth 321, the two second synchronization teeth 421 are meshed with each other and are transmission connected to the output end of the transmission drive motor 410, and the two first synchronization teeth 321 are meshed with each other and are transmission connected to the output end of the cutting drive motor 310.

[0027] Specifically, the transmission drive motor 410 is used to drive the two conveying wheels 430 to rotate relative to each other to convey the steel bars, so that the steel bars pass through the inner side of the guide wheel 210, and the guide wheel 210 rotates to conduct the steel bars and pass them into the working area of ​​the punching assembly 300 for shearing.

[0028] In this embodiment, the conveying wheel 430 and the guide wheel 210 are both rubber roller structures, and the surfaces are provided with guide grooves for the steel bars to pass through.

[0029] Specifically, at the moment of shearing by the shearing blade 341, a feeding gap can be generated by the slipping between the flexible conveying wheel 430 and the surface of the steel bar, thereby preventing the steel bar from sliding during cutting due to continuous conveying.

[0030] In this embodiment, the slide bar 331 is arranged horizontally, and the slide bars 331 are arranged opposite to each other on the surfaces of the two fixing seats 330 and are located on the same straight line. The guide fork 342 is in a U-shaped groove and is slidably sleeved on the surface of the slide bar 331 .

[0032] The working principle and use process of this utility model:

[0033] During the steel bar cutting work, the steel bars pass through the straightening machine into the feeding assembly 400 or are directly fed into the feeding assembly 400 for transportation. The transmission drive motor 410 is used to drive the two conveying wheels 430 to rotate relative to each other to convey the steel bars, so that the steel bars pass through the inner side of the guide wheel 210, and the guide wheel 210 rotates to conduct the steel bars. During the steel bar transportation, the cutting drive motor 310 synchronously drives the first shaft 320 and the crank wheel 350 to rotate. Due to the eccentricity of the outer periphery of the crank wheel 350, the reciprocating sleeve 340 performs eccentric movement under the relative sliding guidance of the slide bar 331 and the shear blade 341. The continuous reciprocating motion of the shear blade 341 is used to shear the steel bars into sections. At the moment of shearing by the shear blade 341, a feeding gap can be generated by the slippage of the flexible conveying wheel 430 and the surface of the steel bar.
