The shearing machine improves the shearing accuracy and avoids the shearing position deviation.

[0004] In the above shearing machine, when the steel bar is driven to be sheared, the cutting knife contacts the steel bar, the steel bar will produce stress to make the two ends of the steel bar be raised, which affects the shearing quality of the steel bar, and the position deviation problem of the steel bar after being subjected to pressure during the cutting process affects the cutting efficiency of the steel bar.

[0005] In addition, due to the different diameters and shapes of the steel bars, the above positioning device is not convenient for clamping the steel bars of different shapes, and the position deviation problem occurs during clamping; therefore, the utility model provides a steel bar shearing device for building construction.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] Please see Figures 1-5 This utility model provides the following technical solution: a steel bar shearing device for building construction, including a base 1, an mounting plate 2 on one side of the base 1, a hydraulic cylinder 3 mounted on the top of the mounting plate 2, a hydraulic rod at the bottom of the hydraulic cylinder 3 extending to the bottom of the mounting plate 2 and connected to a lifting plate 5, pressing blocks 7 connected to both ends of the lifting plate 5 via telescopic rods 71, and a shearing blade 6 mounted on the middle of the bottom of the lifting plate 5 via a mounting frame 51. The hydraulic cylinder 3 drives the lifting plate 5 to descend, thereby causing the pressing blocks 7 to move down via the telescopic rods 71 ​​until they press down on the upper part of the steel bar, further fixing the steel bar with the support block 86; the bottom ends of the pressing blocks 7 fit into the second slot 85 to prevent stress from forming on the steel bar. The lifting end affects the shearing quality of the rebar. As the hydraulic cylinder 3 continues to drive, the shearing blade 6 at the bottom of the lifting plate 5 cuts the rebar. A limiting clamping mechanism 8 is installed on the base 1 below the pressing block 7. One end of the limiting clamping mechanism 8 has a through-hole 82 for the rebar to pass through. An I-shaped clamping base 83 is fixedly installed inside the limiting clamping mechanism 8. An adjustable clamp 10 is connected to the limiting clamping mechanism 8 through the adjusting mechanism 9 and clamps the I-shaped clamping base 83. The motor 92 drives the lead screw 91 to move the adjustable clamp 10 down until it clamps the upper part of the rebar. The bottom ends of the adjustable clamp 10 are just inserted into the first slots 84 on both sides of the middle of the I-shaped clamping base 83, which increases the stability of the adjustable clamp 10. The adjustable clamp 10 and the I-shaped clamping base 83 work together to firmly clamp rebars of different shapes and sizes, avoiding the problem of rebar displacement caused by pressure.

[0033] Specifically, the I-shaped clamping base 83 has first slots 84 on both sides in the middle that are adapted to the adjustable clamp 10; when the adjustable clamp 10 moves down to clamp the steel bar with the I-shaped clamping base 83, the bottom ends of the adjustable clamp 10 just fit into the first slots 84; the bottom of the limiting clamping mechanism 8 has a support block 86 adapted to the pressing block 7 inside the opening 82, and the support block 86 has second slots 85 adapted to the pressing block 7 at both ends; when the pressing block 7 moves down and cooperates with the support block 86 to firmly press the two ends of the steel bar, the bottom ends of the pressing block 7 just fit into the second slots 85; this increases the stability of the adjustable clamp 10 and the pressing block 7.

[0034] Specifically, the adjustment mechanism 9 includes a lead screw 91 and a guide rod 94; the lead screw 91 and the guide rod 94 are respectively installed in the slide grooves 81 on both sides of the limiting clamping mechanism 8, and the two ends of the adjustable clamp 10 are set on the lead screw 91 and the guide rod 94 through the sliders 93. The top end of the lead screw 91 is driven by a motor 92; the motor 92 drives the lead screw 91 to move the adjustable clamp 10 down until it is clamped on the upper part of the steel bar.

[0035] Specifically, the adjustable clamp 10 is driven by the lead screw 91 driven by the motor 92 to adjust up and down inside the limiting clamping mechanism 8. The adjustable clamp 10 and the I-shaped clamping base 83 cooperate with each other to fix and clamp steel bars of different sizes.

[0036] Specifically, the top two ends of the lifting plate 5 are provided with limiting rods 4 that slide within the limiting holes of the mounting plate 2; the bottom ends of the lifting plate 5 are connected with compression springs 72 that are sleeved on the telescopic rods 71 ​​and connected to the top of the pressing block 7.

[0037] In addition, casters 11 are installed at the bottom of the base 1. The base 1 contains a battery box that supplies power to the hydraulic cylinder 3 and the motor 92, and the base 1 is equipped with switches for controlling the hydraulic cylinder 3 and the motor 92.

[0038] The working principle and usage process of this utility model are as follows: The device is moved to the steel bar cutting station in building construction by means of the moving wheels 11; when in use, the steel bar is inserted into the through-hole 82 at one end of the limiting clamping mechanism 8, and then through the limiting clamping mechanism 8 and out through the through-hole of the other limiting clamping mechanism 8, so that the steel bar is placed on the I-shaped clamping base 83 and the support block 86 inside the limiting clamping mechanism 8; the steel bar is cut to the corresponding length as needed. First, the switch is turned on, and the motor 92 drives the lead screw 91 to move the adjustable clamp 10 down until it clamps the upper part of the rebar. The bottom ends of the adjustable clamp 10 are precisely engaged in the first slots 84 on both sides of the middle of the I-shaped clamping base 83, which increases the stability of the adjustable clamp 10. The adjustable clamp 10 and the I-shaped clamping base 83 work together to firmly clamp rebars of different shapes and sizes, preventing the rebar from shifting due to pressure. During shearing, the hydraulic cylinder 3 is activated to drive the lifting plate 5 down, which in turn drives the pressing block 7 down through the telescopic rod 71 until it presses down on the upper part of the rebar, further fixing the rebar with the support block 86. The bottom ends of the pressing block 7 are precisely engaged in the second slots 85, preventing the rebar from being stressed and warped, which would affect the shearing quality. As the hydraulic cylinder 3 continues to drive, the shearing blade 6 at the bottom of the lifting plate 5 shears the rebar. During the shearing process, the pressing block 7 presses the ends of the rebar more firmly under the force of the compression spring 72, eliminating the rebar from shifting during shearing and improving cutting efficiency.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
