[0003] Existing rebar shearing machines have a certain height on their worktable for ease of operation. This causes the cut rebars to fall to the ground, which not only makes the surface of the rebars contaminated with dust, but also may damage the fallen rebars. The rebars scattered on the ground are inconvenient to collect, and it is impossible to guarantee the consistency of the length of the same batch of rebars during the cutting process.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1 and Figure 4 As shown, a rebar cutting device for construction includes a workbench 1, with movable discs symmetrically arranged on the upper surface of the workbench 1. A frame 3 is provided at one end of the surface of the workbench 1, and a hydraulic cutter 4 is provided on the top of the frame 3. A cutter 5 is installed at the output end of the hydraulic cutter 4 and slides inside the frame 3. A support seat 6 is provided at one end of the upper surface of the workbench 1 near the frame 3, and the cutter 5 is placed outside the support seat 6. A boss 7 is provided on the side surface of the workbench 1 near the frame 3, with slide rods symmetrically arranged at the ends of the boss 7. Slide seats 8 are slidably installed on the surfaces of the two slide rods 9. U-shaped grooves are opened on the upper surfaces of both the boss 7 and the slide seats 8. Scale rods 12 are symmetrically arranged on one side of the boss 7, with the two scale rods 12 placed above the boss 7 and on both sides below the support seat 6. Baffles 13 are slidably installed above the surfaces of the two scale rods 12.

[0023] According to the above structure, the hydraulic cutter 4 drives the cutter 5 to move downward, thereby cutting the steel bar passing below. The steel bar forward movement can be achieved by adjusting the position of the baffle 13 so that the length of the steel bar cut is the distance between the support seat 6 and the baffle 13. The cut steel bar will fall down between the two scale rods 12 and into the U-shaped groove on the upper surface of the boss 7 and the slide 8, so as to facilitate the collection of the steel bar.

[0024] like Figures 1-3 As shown, a locking box 14 is provided below the side surface of the baffle 13 facing away from the worktable 1. Two scale rods 12 pass through the locking box 14. The locking box 14 has symmetrical storage holes 15 on both sides inside. A pressing plate 16 is slidably installed inside the two storage holes 15 facing away from each other. A rubber pad 17 is glued to the surface of the pressing plate 16. The rubber pad 17 is in contact with the side surface of the scale rod 12.

[0025] According to the above structure, the scale rod 12 is uniformly engraved on its surface. At the same time, the scale rod 12 is squeezed by the pressure plate 16 in the air, so that the position of the baffle 13 is fixed. The rubber pad 17 can prevent excessive pressure from damaging the scale rod 12.

[0026] like Figure 2 and Figure 3 As shown, a cavity 18 is formed in the center of the locking box 14. A connecting rod 25 is provided at the end of the extrusion plate 16 away from the rubber pad 17. The connecting rod 25 passes through the receiving hole 15. A ball head 27 is provided at the end of the connecting rod 25 away from the extrusion plate 16. The ball head 27 is placed inside the cavity 18. A spring B26 is sleeved on the surface of the connecting rod 25. The spring B26 is placed inside the cavity 18. One end of the spring B26 is in contact with the surface of the ball head 27. A control rod 19 slides vertically through the inside of the locking box 14. A cone block 21 is provided on the surface of the control rod 19. The control rod 19 is wider at the top and narrower at the bottom. The two ball heads 27, which are opposite to the ends of the connecting rod 25, are in contact with the two sides of the cone block 21. A knob 20 is provided on the top of the control rod 19 and is positioned above the locking box 14. A spring A23 is fitted on the surface of the control rod 19 and is positioned above the locking box 14. The top of the spring A23 is in contact with the lower surface of the knob 20. A limit groove 24 is provided on the lower surface of the locking box 14. The limit groove 24 is fan-shaped with the axis of the control rod 19 as the center. A limit rod 22 is provided at the bottom of the control rod 19 and corresponds to the limit groove 24.

[0027] According to the above structure, when the knob 20 is pressed, the cone block 21 can be moved down to push the extrusion plate 16 outward. At the same time, the limiting rod 22 can be moved down to disengage from the limiting groove 24. At this time, rotating the knob 20 causes the limiting rod 22 and the limiting groove 24 to be misaligned, thereby maintaining the stability of the position of the extrusion plate 16.

[0028] like Figure 4 As shown, a slot 10 is provided on the inner side of the end of the slide block 8 away from the boss 7. A card plate 11 is inserted into the inner side of the slot 10. The card plate 11 can be selected to be used according to the actual situation. When the cut steel bar is placed in the U-shaped groove, the slide block 8 can be pushed to move, and then the card plate 11 will squeeze multiple steel bars to make the steel bars neat and easy to bundle.

[0029] The working principle of this utility model is as follows: The steel bar to be cut is passed between two adjacent moving discs 2. The rotation of the moving discs 2 drives the steel bar to move forward automatically, so that the steel bar passes through the support base 6 and below the cutter 5. The baffle 13 is adjusted according to the size of the steel bar to be cut, so that the end of the steel bar is limited by the baffle 13 to keep the length of the steel bars in the same batch consistent. Pressing down the knob 20 causes the control rod 19 and the cone 21 to move down. The cone 21 squeezes the ball heads 27 on both sides, so that the two connecting rods 25 move away from each other. Then, the extrusion plate 16 moves closer to the scale rod 12. The rubber pad 17 squeezes the scale rod 12 to keep the baffle 13 and the scale rod 12 fixed. At the same time, during the downward movement of the control rod 19, the limiting rod 22 can be moved down, exceeding the limiting groove 24. Rotating the knob 20 causes the limiting rod 22 to move down. When the limit groove 24 is misaligned, the limit rod 22 comes into contact with the lower surface of the locking box 14, preventing the control rod 19 from moving upward. At this time, the springs A23 and B26 are held in place by the limit and store force. The hydraulic cutter 4 drives the cutter 5 to cut the steel bar. The cut steel bar falls between the two scale rods 12 and into the U-shaped groove on the surface of the boss 7 and the slide 8. The position of the slide 8 can be adjusted according to the length of the cut steel bar to collect the cut steel bar. Different lengths can be used. The cut steel bar can also be kept inside the boss 7 and the slide 8 by the cooperation of the clamping plate 11 and the clamping groove 10. It is also placed between the worktable 1 and the clamping plate 11. The slide 8 can be moved closer to the worktable 1, and then the clamping plate 11 can be used to squeeze multiple cut steel bars to keep the steel bars flat after packaging.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
