[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown in the figure, the present invention provides a cutting device for building steel bars, including a cutting machine 1 and a clamp 2. The clamp 2 is opened on the left side of the cutting machine 1. A telescopic block 3 is movably connected to the right side of the inner wall of the clamp 2. A limiting block 4 is fixedly connected to the front side of the inner wall of the clamp 2 and the side corresponding to the telescopic block 3. A pressing structure 5 is fixedly connected to the top of the cutting machine 1 and directly above the clamp 2. A clamping structure 6 is provided on the top of the cutting machine 1 and in front of the clamp 2.

[0023] refer to Figure 3 The clamping structure 5 includes a support frame 501, a first electric cylinder 502, a lifting plate 503, and two clamping blocks 504. The support frame 501 is fixedly connected to the top of the cutting machine 1 and is located directly above the clamping opening 2. The first electric cylinder 502 is fixedly connected to the top of the support frame 501, and the output end of the first electric cylinder 502 passes through and extends out of the bottom of the support frame 501. The lifting plate 503 is fixedly connected to the output end of the first electric cylinder 502. The two clamping blocks 504 are respectively fixedly connected to the front and rear sides of the bottom of the lifting plate 503.

[0024] The above solution is adopted: by setting up the clamping structure 5, the steel bars in the clamp 2 can be clamped to prevent them from moving when cut.

[0025] refer to Figure 3 The bottom of the clamping block 504 has an arc-shaped opening.

[0026] The above solution is adopted: by setting the arc opening, it can fit the surface of the steel bar, increasing the contact area between the clamping block 504 and the steel bar.

[0027] refer to Figure 2 A vertical hole 7 is provided on the left side of the cutting machine 1. The clamping structure 6 is fixedly connected to the top of the cutting machine 1 and slidably connected inside the vertical hole 7.

[0028] The above solution is adopted: by setting the vertical hole 7, the movement trajectory of the clamping structure can be provided, and then the steel bar can be clamped.

[0029] refer to Figure 4 The clamping structure 6 includes a second electric cylinder 601, a pressure plate 602, a third electric cylinder 603, and a support plate 604. The second electric cylinder 601 is fixedly connected to the bottom of the cutting machine 1. The pressure plate 602 is fixedly connected to the output end of the second electric cylinder 601 and is slidably connected to the inside of the vertical hole 7. The right side of the pressure plate 602 extends into the inside of the clamping opening 2. The third electric cylinder 603 is fixedly connected to the bottom of the cutting machine 1 and is located below the second electric cylinder 601. The support plate 604 is fixedly connected to the output end of the third electric cylinder 603 and is slidably connected to the inside of the vertical hole 7 and extends into the inside of the clamping opening 2.

[0030] The above solution involves setting up a clamping structure 6 to clamp the reinforcing bars, preventing them from moving during cutting.

[0031] refer to Figure 2 A limiting groove 8 is provided on the right side of the inner wall of the clamp 2, and the pressure plate 602 and the support plate 604 are slidably connected to its surface.

[0032] By adopting the above solution, the pressure plate 602 and the support plate 604 can be restricted by setting the limiting groove 8, so as to prevent them from tilting when moving.

[0033] refer to Figure 2 and Figure 4 The front and rear sides of the inner wall of the vertical hole 7 are provided with sliding grooves 9, and the front and rear sides of the pressure plate 602 and the support plate 604 are fixedly connected with sliders 10, and the sliders 10 are slidably connected inside the sliding grooves 9.

[0034] By adopting the above solution, the pressure plate 602 and the support plate 604 can be restricted by setting the slide groove 9 and the slider 10, thereby improving their stability during movement.

[0035] The working principle of this utility model:

[0036] When in use, place the reinforcing bar inside the clamp 2 of the cutting machine 1 and determine the size to be cut. Then start the first electric cylinder 502. The first electric cylinder 502 drives the lifting plate 503 to descend. The lifting plate 503 drives the two clamping blocks 504 to clamp the reinforcing bar. Then start the second electric cylinder 601 and the third electric cylinder 603. Their output ends drive the pressure plate 602 and the support plate 604 to move respectively, and then clamp the reinforcing bar extending from the clamp 2. At this time, the reinforcing bar can be cut by the telescopic block 3.

[0037] In summary, this rebar cutting device, through the coordinated use of a cutting machine 1, a clamp 2, a telescopic block 3, a limiting block 4, a pressing structure 5, a support frame 501, a first electric cylinder 502, a lifting plate 503, a pressing block 504, a clamping structure 6, a second electric cylinder 601, a pressure plate 602, a third electric cylinder 603, a support plate 604, a vertical hole 7, a limiting groove 8, a sliding groove 9, and a slider 10, solves the problem that if the rebar is not fixed during cutting, it will cause the rebar to shift or vibrate, resulting in uneven cutting by the blade, forming bevels, burrs, or uneven cross-sections.
