Description

Technical Field

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

[0002] Chinese patent application number 202220693593.4 discloses a steel bar cutting device for steel bar processing. By setting fixed support blocks and floating support blocks on both sides of the upper and lower shearing blades to support the steel bar cutting process, the two ends of the steel bar at the cutting position can be fixed and pressed tightly during the cutting process, which can effectively prevent the steel bar from loosening.

[0003] However, existing steel bars require workers to manually position them in the appropriate location before the cutting machine can cut them. This placement method is cumbersome, and workers need to reposition the steel bars after each cut, which prolongs the cutting time, resulting in low cutting efficiency and making it inconvenient to continuously carry out cutting operations. Some cutting equipment is also equipped with a material stop structure, but the position of the material stop structure is fixed and can only position steel bars of a single length. When it is necessary to change the cutting length of the steel bars, the material stop structure needs to be removed and reinstalled, which is time-consuming and labor-intensive.

[0037] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.

[0038] Working principle: All electrical components mentioned in this application are connected to an external power supply and control switch during use. After the utility model is installed, first check the installation, fixation, and safety protection of the utility model, and then it can be used. Before use, the electric slide rail 5 drives the sliding seat 6 to move, which in turn drives the baffle 7 to move, so that the distance between the cutting mechanism 3 and the baffle 7 is the preset cutting length of the steel bar. Then, the second drive motor 68 is started, which drives the second lead screw 67 to rotate. The second lead screw 67 drives the second slide rod 66 to move within the second limit frame 65, thereby driving the third support rod 62 and the fourth support rod 63 to rotate, which drives the first top plate 61 to move upward, so that the first top plate 61 drives the baffle 7 to extend out of the second roller conveyor 4 to block the steel bar from moving further.

[0039] In operation, workers place the reinforcing bars on the first roller conveyor 1, which then transports them. The bars move past the cutting mechanism 3 via the lifting roller conveyor 2, and then continue moving via the second roller conveyor 4 until they stop against the baffle 7. The first drive motor 29 then drives the first lead screw 28 to rotate, causing the lead screw 28 to move the first slide rod 27 within the first limit frame 26. This causes the slide rod 27 to rotate the first support rod 23 and the second support rod 24, lowering the roller conveyor top frame 22 to create space for cutting the reinforcing bars. The hydraulic device 32 is then activated, starting the cutting blade 33 to cut the reinforcing bars. The cut reinforcing bars are placed on the second roller conveyor 4. The second drive motor 68 is then activated to lower the first top plate 61, moving the baffle 7 into the second roller conveyor 4 and transporting the reinforcing bars outwards. The remaining reinforcing bars fall onto the roller conveyor top frame 22, awaiting further cutting.

[0040] Example 2: Please refer to Figures 4-5 A steel bar cutting device for steel bar processing, which differs from Embodiment 1 in that the lifting component includes: a second top plate 611, a hydraulic cylinder 612 and an output shaft 613. Two hydraulic cylinders 612 are symmetrically installed on the top of the sliding seat 6. The output end of the hydraulic cylinder 612 is provided with an output shaft 613. The top of the two output shafts 613 is fixedly installed with the second top plate 611. A baffle 7 is fixedly installed on the top of the second top plate 611.

[0041] The electric slide rail 5 drives the sliding seat 6 to move, which in turn drives the baffle 7 to move, so that the distance between the cutting mechanism 3 and the baffle 7 is the preset cutting length of the steel bar. Then, the hydraulic cylinder 612 is activated, which drives the output shaft 613 to move, causing the second top plate 611 to move upward. The second top plate 611 drives the baffle 7 to extend out of the second roller conveyor 4, which is used to block the steel bar from moving further.

[0042] Example 3: Please refer to Figures 6-9A rebar cutting device for rebar processing, differing from Embodiment 1 in that the lifting components include: an outer cylinder 614, a third top plate 615, and a supporting half-shell 624. The outer cylinder 614 is fixedly installed on the top of the sliding seat 6. A hexagonal groove 620 is formed inside the outer cylinder 614, communicating with the top opening of the outer cylinder 614. A hexagonal slider 621 is slidably connected inside the hexagonal groove 620. A third lead screw 619 is threadedly fitted in the middle of the hexagonal slider 621. A fixing block 623 is fixedly installed at the opening of the outer cylinder 614. The top of the third lead screw 619 is rotatably connected to the fixing block 623, and the bottom of the third lead screw 619 is rotatably connected to the inner bottom wall of the outer cylinder 614. A worm gear 618 is fixedly fitted on the outer wall of the third lead screw 619. A worm 617 is rotatably connected inside the outer cylinder 614, meshing with the worm gear 618. A geared motor 616 is fixedly installed on the outer wall. One end of the worm gear 617 extends rotatably out of the outer cylinder 614. The geared motor 616 is connected to the extended end of the worm gear 617. A top cylinder 622 is fixedly installed on the top of the hexagonal slider 621. A third lead screw 619 extends through the top cylinder 622. A support half-shell 624 is fixedly installed on the top of the hexagonal slider 621. The top of the support half-shell 624 slides vertically through the fixed block 623. A third top plate 615 is fixedly installed on the top of the support half-shell 624. A baffle 7 is fixedly installed on the top of the third top plate 615. The geared motor 616 drives the worm gear 617 to rotate, which in turn drives the third lead screw 619 to rotate. The third lead screw 619 drives the hexagonal slider 621 and the support half-shell 624 to move upward, which in turn drives the third top plate 615 to move upward, changing the position of the baffle 7.

[0043] The electric slide rail 5 drives the sliding seat 6 to move, which in turn drives the baffle 7 to move, so that the distance between the cutting mechanism 3 and the baffle 7 is the preset cutting length of the steel bar. Then, the reduction motor 616 is started, which drives the worm 617 to rotate, causing the worm 617 to mesh with the worm wheel 618 to rotate, which in turn drives the third lead screw 619 to rotate. The third lead screw 619 drives the hexagonal slider 621 to slide in the hexagonal groove 620, which in turn drives the support half shell 624 to move upward, which in turn drives the third top plate 615 and the baffle 7 to move upward, so that the baffle 7 extends out of the second roller conveyor 4 to stop the steel bar from moving further.

[0044] The first roller conveyor, the cutting mechanism, the second roller conveyor, the electric slide rail, the roller conveyor top frame, the first drive motor, the second drive motor, the hydraulic cylinder, and the geared motor in this case are existing technologies. The cutting mechanism has the same structure and connection method as those in the cited documents. As long as the first roller conveyor, the cutting mechanism, the second roller conveyor, the electric slide rail, the roller conveyor top frame, the first drive motor, the second drive motor, the hydraulic cylinder, and the geared motor meet the requirements of this case, they are all acceptable and are not limited to a single model.
