Description

Technical Field

[0001] This utility model relates to the field of steel bar processing equipment technology, and in particular to a steel bar cutting device for steel bar testing. Background Technology

[0002] The main purpose of steel bar sampling is to test the mechanical properties, chemical composition, and physical properties of the steel bars to ensure that their quality meets relevant standards. The typical sampling method involves cutting a 1-meter section of the steel bar for testing. Sampling locations should avoid areas with obvious rust, cracks, or significant deformation on the steel bar surface.

[0003] Rebar cutting devices used for rebar inspection generally use direct cutting to obtain rebar of the corresponding length. The cutting equipment is usually hydraulic pliers or power pliers, etc. However, the direct cutting method is generally suitable for rebars with smaller diameters. When the diameter of the rebar to be cut is larger, the contact area between the cut surface of the rebar and the cutting tool is larger. In this way, the rebar will be subjected to greater squeezing force by the cutting tool during the cutting process, and the rebar is more likely to deform. The above situation will not occur with rebars with smaller diameters. Utility Model Content

[0004] To overcome the problem that when the diameter of the steel bar to be cut is large, the steel bar will be subjected to greater compressive force by the cutting tool, and the steel bar as a whole is prone to deformation.

[0005] The technical solution of this utility model is as follows: a rebar cutting device for rebar inspection, including a working base and a mounting plate one, as well as a motor and a mounting cover. The mounting plate one is fixedly installed on one side of the upper end of the working base, and the motor is fixedly installed on one side of the mounting plate one. The mounting cover is rotatably connected to one side of the mounting plate one. The output end of the motor is fixedly connected to the mounting cover. A three-jaw chuck for clamping and fixing one end of the rebar is fixedly installed inside the mounting cover. A mounting plate two is fixedly installed on the upper end of the working base. A roller shaft is rotatably connected between the two mounting plates two. A pressure roller for pressing one end of the rebar is provided on the upper end of the roller shaft. A hydraulic clamp mounting base is provided on the upper end of the working base.

[0006] Preferably, a support frame is fixedly installed on the upper end of the mounting plate 2, and limiting grooves are provided on both sides of the support frame. A sliding frame is slidably connected in the limiting grooves, and the pressure roller is rotatably set at the lower end of the sliding frame.

[0007] Preferably, the upper end of the support frame is threaded with a threaded rod, the upper end of the threaded rod is fixedly connected with an anti-slip handle, the upper end of the sliding frame is fixedly installed with a bearing seat, the bearing seat is rotatably connected to the lower end of the threaded rod, and the threaded rod is used to adjust the height of the pressure roller.

[0008] Preferably, the upper end of the mounting plate two is provided with a slot for one end of the reinforcing bar to pass through, and two rollers are respectively located on both sides of the slot at the upper end of the mounting plate two, with the pressure roller located directly above the two rollers.

[0009] Preferably, a guide shaft is fixedly installed on the upper end of the working base, and the hydraulic clamp mounting base is slidably set on the surface of the guide shaft. Bearing seats two are fixedly installed on both sides of the working base, and a bidirectional screw is rotatably connected between the two bearing seats two. The bidirectional screw is threadedly connected to the two hydraulic clamp mounting bases.

[0010] Preferably, a bearing housing three is fixedly installed on one side of the working base, and a worm gear is rotatably connected between the two bearing housing threes. A worm wheel is fixedly connected to one end of the bidirectional screw, and the worm wheel meshes with the worm gear.

[0011] Preferably, one end of the worm is fixedly connected to a rotating handle, which is used to move the hydraulic clamp mounting base. Both the worm wheel and the worm are located at the lower end of one side of the working platform.

[0012] The beneficial effects of this utility model are: 1. When the rebar cutting device for rebar testing cuts rebar, compared to directly cutting the rebar, it performs short-distance shearing in all directions, resulting in a smaller single contact area between the cutting tool and the rebar cut surface. Therefore, the rebar cut surface is subjected to less compressive force from the cutting tool, which allows for more stable cutting of larger diameter rebars without deformation of the rebar as a whole. 2. This rebar inspection and rebar cutting device can quickly adjust the cutting positions of the two cutting devices according to the required length of the rebar to be cut, and has a self-locking effect to ensure that the position of the cutting devices will not move during operation. The two cutting devices start simultaneously to cut the rebar. This rebar inspection and rebar cutting device can quickly fix the rebar and is suitable for fixing rebars of different diameters.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a rebar cutting device for rebar inspection, including a working base 1 and a mounting plate 2, as well as a motor 3 and a mounting cover 4. The mounting plate 2 is fixedly mounted on one side of the upper end of the working base 1, and the motor 3 is fixedly mounted on one side of the mounting plate 2. The mounting cover 4 is rotatably connected to one side of the mounting plate 2. The output end of the motor 3 is fixedly connected to the mounting cover 4. A three-jaw chuck 5 for clamping and fixing one end of the rebar is fixedly mounted inside the mounting cover 4. A second mounting plate 6 is fixedly mounted on the upper end of the working base 1. A roller shaft 7 is rotatably connected between the two plates 6. The upper end of the roller shaft 7 is equipped with a pressure roller 10 for pressing one end of the steel bar. The upper end of the working base 1 is equipped with a hydraulic clamp mounting base 16. When the steel bar cutting device for steel bar detection cuts the steel bar, compared with directly cutting the steel bar, by performing short-distance shearing in all directions, the single contact area between the cutting tool of the cutting device and the steel bar cutting surface is smaller. Therefore, the cutting surface of the steel bar is subjected to less squeezing force by the cutting tool, so that larger diameter steel bars can be cut more stably without deformation of the steel bar as a whole.

[0017] Please see Figure 3 and Figure 4In this embodiment, a support frame 8 is fixedly installed on the upper end of the mounting plate 2 6. Limiting grooves 11 are provided on both sides of the support frame 8. A sliding frame 9 is slidably connected within the limiting grooves 11. The pressure roller 10 is rotatably disposed at the lower end of the sliding frame 9. A threaded rod 13 is threadedly connected to the upper end of the support frame 8. An anti-slip handle 14 is fixedly connected to the upper end of the threaded rod 13. A bearing seat 12 is fixedly installed on the upper end of the sliding frame 9. The bearing seat 12 is rotatably connected to the lower end of the threaded rod 13. The threaded rod 13 is used to adjust the height of the pressure roller 10. The upper end of the mounting plate 2 6 has a slot for one end of the reinforcing bar to pass through. Two roller shafts 7 are located on both sides of the slot at the upper end of the mounting plate 2 6. The pressure roller 10 is located directly above the two roller shafts 7. In use, the hydraulic cutting device is first fixedly installed on the hydraulic clamp mounting base 16. One end of the reinforcing bar is then passed through the two roller shafts 7 and the pressure roller 10. Between 0 and 1, insert one end of the rebar into the three-jaw chuck 5 and lock the three-jaw chuck 5. The three-jaw chuck 5 fixes one end of the rebar. Then, rotate and tighten the anti-slip handle 14. At the same time, the pressure roller 10 connected to the lower end of the sliding frame 9 presses down on the other end of the rebar, thus fixing the rebar. When cutting the rebar, first start the cutting device on the hydraulic clamp mounting base 16. After the cutting device cuts a certain distance, release the cutting device and start the motor 3 fixedly installed on one side of the mounting plate 2. The rebar fixed by the three-jaw chuck 5 rotates at the same time. Start the cutting device again to cut a certain distance. Then release the cutting device again and start the motor 3. Repeat the above steps until the rebar is cut. By cutting short distances in various directions, it is possible to cut larger diameter rebars more stably.

[0018] Please see Figure 1 and Figure 5In this embodiment, a guide shaft 15 is fixedly installed on the upper end of the working base 1, and a hydraulic clamp mounting base 16 is slidably disposed on the surface of the guide shaft 15. Bearing seats 17 are fixedly installed on both sides of the working base 1, and a bidirectional screw 18 is rotatably connected between the two bearing seats 17. The bidirectional screw 18 is threadedly connected to the two hydraulic clamp mounting bases 16. A bearing seat 20 is fixedly installed on one side of the working base 1, and a worm gear 21 is rotatably connected between the two bearing seats 20. A worm wheel 19 is fixedly connected to one end of the bidirectional screw 18, and the worm wheel 19 meshes with the worm gear 21. A rotating handle 22 is fixedly connected to one end of the worm gear 21, and the rotating handle 22 is used to drive the hydraulic clamp mounting base 16. The worm gear 19 and worm 21 are both located at the lower end of one side of the working base 1 to prevent workers' fingers from accidentally getting stuck between them. The worm gear 19 and worm 21 are used to save effort. After the steel bar is fixed, the distance between the two hydraulic clamp mounting bases 16 is adjusted according to the required length of the steel bar to be cut. Rotating the handle 22 causes the worm 21 to rotate, and the worm gear 19, which is meshed with the worm 21, rotates at the same time. The double-acting screw 18 rotates simultaneously between the two bearing seats 17. The two hydraulic clamp mounting bases 16, which are threadedly connected to the double-acting screw 18, move towards the center at the same time, thus realizing the adjustment of the distance between the two hydraulic clamp mounting bases 16.

[0019] In use, first, the hydraulic cutting device is fixedly installed on the hydraulic clamp mounting base 16. One end of the rebar is passed through the two rollers 7 and the pressure roller 10. Then, one end of the rebar is inserted into the three-jaw chuck 5 and locked. The three-jaw chuck 5 fixes one end of the rebar. Then, the anti-slip handle 14 is rotated and tightened. The anti-slip handle 14 drives the threaded rod 13 to rotate at the bearing seat 12. The threaded rod 13 is threadedly connected to the support frame 8. The threaded rod 13 moves downward, and the sliding frame 9, which is rotatably connected to the lower end of the threaded rod 13, moves downward at the same time. In this way, the pressure roller 10, which is rotatably connected to the lower end of the sliding frame 9, presses the other end of the rebar downward, thus fixing the rebar.

[0020] After the reinforcing bars are fixed, adjust the distance between the two hydraulic clamp mounting bases 16 according to the required length of the reinforcing bars to be cut. Rotate the handle 22, which drives the worm gear 21 to rotate between the two bearing seats 20. The worm wheel 19, which is meshed with the worm gear 21, rotates at the same time. The worm wheel 19 is fixedly connected to one end of the double-acting screw 18. The double-acting screw 18 rotates between the two bearing seats 17 at the same time. The two hydraulic clamp mounting bases 16, which are threadedly connected to the double-acting screw 18, move towards the middle at the same time. This achieves the adjustment of the distance between the two hydraulic clamp mounting bases 16.

[0021] When cutting reinforcing bars, first start the cutting device on the hydraulic clamp mounting base 16. After the cutting device cuts a certain distance, release the cutting device and start the motor 3 fixedly mounted on one side of the mounting plate 2. The motor 3 drives the mounting cover 4 to rotate, and the reinforcing bar fixed by the three-jaw chuck 5 rotates at the same time. Start the cutting device again to cut a certain distance, and then release the cutting device again and start the motor 3. Repeat the above steps until the reinforcing bar is cut. By cutting short distances in all directions, the single contact area between the cutting tool of the cutting device and the cutting surface of the reinforcing bar is smaller, so that larger diameter reinforcing bars can be cut more stably.

[0022] Through the above steps, when the rebar cutting device for rebar detection cuts the rebar, compared to directly cutting the rebar, by performing short-distance shearing in all directions, the single contact area between the cutting tool of the cutting device and the rebar cutting surface is smaller. Therefore, the cutting surface of the rebar is subjected to less extrusion pressure from the cutting tool, which allows for more stable cutting of larger diameter rebars without deformation of the rebar as a whole.
