Description

Technical Field

[0001] This invention relates to the field of steel bar processing equipment, and more specifically to a fixed-length segment cutting device for steel bar processing. Background Technology

[0002] In the construction industry, steel bars are mostly cut into sections using cutting machines. When workers need to cut steel bars, they mostly use hand-operated cutting machines, which is labor-intensive and has low safety performance. Large steel bar cutting devices are bulky and inconvenient to use. Therefore, a fixed-length section cutting device for steel bar processing is proposed to facilitate the section cutting of steel bars and improve the convenience of steel bar cutting. Summary of the Invention

[0003] To address the problems in the prior art, the present invention provides a fixed-length segmented cutting device for steel bar processing, which facilitates segmented cutting of steel bars and improves the convenience of steel bar cutting.

[0004] The technical solution adopted by the present invention to solve its technical problem is a fixed-length segmented cutting device for steel bar processing, including a main body, a number of sets of rollers at the bottom of the main body, and a through slot inside the main body. The slot is horizontal and the steel bar passes through the slot.

[0005] The slot is provided with a clamping and conveying structure and a cutting structure. The top of the main body is provided with an adjustable driving structure, which is used to drive the clamping and conveying structure or the cutting structure. The top of the main body away from the driving structure is provided with a pressing structure, which is used to adjust the adjustable driving structure.

[0006] By adopting the above technical solution, when it is necessary to cut the steel bar, the steel bar to be cut is passed through the slot, and the clamping and conveying structure is driven by the adjustable drive structure. The clamping and conveying structure drives the steel bar to be cut to move. When the steel bar moves to a certain position, one end of the steel bar is pressed and contacted with the extrusion structure, and the extrusion structure is driven to move. When the extrusion structure moves to a certain position, the adjustable drive structure no longer drives the clamping and conveying structure to work, thereby determining the length of the steel bar to be cut.

[0007] When the adjustable drive structure stops driving the clamping and conveying structure, it drives the cutting structure to cut the steel bar. After cutting, one end of the steel bar is no longer in contact with the extrusion structure. The reset of the extrusion structure causes the adjustable drive structure to stop driving the cutting structure. At the same time, the adjustable drive structure drives the clamping and conveying structure again and continues to convey the steel bar to be cut, and performs the next segmented cutting operation. This improves the convenience of cutting steel bars and enhances the flexibility of use according to the actual usage environment.

[0008] It should be noted that when the steel bars to be cut are large, the clamping and conveying structure cannot drive the steel bars to move. In this case, the main body is driven to move by several sets of rollers at the bottom of the main body. After the main body moves to a certain position, the cutting structure is driven to cut the steel bars. This makes it easier to automatically adjust the cutting method according to the actual specifications of the steel bars, and further improve the convenience of cutting.

[0009] Specifically, the clamping and conveying structure includes a cavity inside the main body, a first output shaft inside the cavity, one end of the first output shaft passing through the main body and rotatably connected to the main body, and a conveying roller fixedly connected to the other end of the first output shaft;

[0010] The cavity is equipped with two sets of second output shafts, which are located below the first output shaft. The two ends of the second output shaft are rotatably connected to elastic brackets. The lower end of the elastic brackets is fixedly connected to the bottom of the main cavity. An auxiliary roller is fixedly connected to the second output shaft. The conveying roller and the auxiliary roller are both rolledly connected to the outside of the reinforcing bar. The adjustable drive structure is used to drive the first output shaft to rotate.

[0011] By adopting the above technical solution, the steel bars to be cut are passed through the slot. At this time, the steel bars are located between the conveying roller and two sets of auxiliary rollers. The first output shaft is driven to rotate by the adjustable drive structure. When the first output shaft rotates, it drives the conveying roller to rotate. The conveying roller is used to transport the steel bars to be cut. At the same time, the two sets of auxiliary rollers can improve the stability of the steel bar transportation and facilitate the segmented cutting of the steel bars after they are transported to a certain position. The elastic support can be used to clamp steel bars of different specifications and ensure the stability of steel bar transportation.

[0012] Specifically, the adjustable drive structure includes a drive motor fixedly mounted on the upper surface of the main body. The output end of the drive motor is connected to a telescopic coupling. A drive shaft is connected to the end of the telescopic coupling away from the drive motor. The upper surface of the main body is provided with a first mounting plate and a second mounting plate. A first spiral tooth is rotatably connected to the side of the first mounting plate away from the drive shaft, and a second spiral tooth is rotatably connected to the side of the second mounting plate near the drive shaft. The drive shaft passes sequentially through the first mounting plate, the first spiral tooth, the second spiral tooth, and the second mounting plate, and is slidably connected to the first mounting plate, the first spiral tooth, the second spiral tooth, and the second mounting plate, respectively. One side of the first spiral tooth and the second spiral tooth…

[0013] The inner walls of the first and second volutes are respectively provided with a plurality of circumferentially distributed first and second slots. The outer side of the drive shaft is provided with a first and a second block. The first block is initially located in the first slot, and the second block is initially disengaged from the second slot. The drive shaft is fixedly connected to the extrusion structure.

[0014] A third output shaft is provided below the first spiral tooth. A first gear is fixedly connected to one end of the third output shaft. The first gear meshes with the first spiral tooth for transmission. A first pulley is fixedly connected to the other end of the third output shaft. The third output shaft is rotatably connected to a first support plate. The first support plate is fixedly connected to the upper surface of the main body. A second pulley is fixedly connected to the end of the first output shaft away from the conveying roller. The first pulley and the second pulley are driven by a first transmission belt.

[0015] A third vortex is horizontally arranged on one side of the second vortex. The lower end of the third vortex passes through the main body and meshes with the cutting structure for transmission. A second gear is fixedly connected to the upper end of the third vortex. The second gear meshes with the second vortex for transmission. A second support plate is rotatably connected to the side of the second gear away from the third vortex. The second support plate is fixedly connected to the upper surface of the main body.

[0016] By adopting the above technical solution, the steel bar to be cut is passed through the slot, and the drive shaft is driven to rotate by the drive motor and the telescopic coupling. When the drive shaft rotates, the first worm gear rotates by the first locking block located in the first slot. When the first worm gear rotates, it meshes with the first gear and drives the third output shaft to rotate. When the third output shaft rotates, it drives the first pulley to rotate. The second pulley rotates by the first transmission belt. When the second pulley rotates, it drives the first output shaft to rotate synchronously, and thus drives the conveyor roller to rotate. When the conveyor roller rotates, it moves the steel bar, which facilitates the movement of the steel bar to be cut.

[0017] Once the reinforcing bar has moved to a certain position, one end of the reinforcing bar comes into contact with the extrusion structure, causing the extrusion structure to move. As the extrusion structure moves, the drive shaft moves synchronously. The telescopic coupling improves the ease of movement of the drive shaft. When the drive shaft moves to a certain position, the first locking block disengages from the first locking slot, and the conveying roller is no longer driven to rotate, thus stopping the conveying of the reinforcing bar and determining the cutting length. When the first locking block disengages from the first locking slot, the second locking block moves into the second locking slot and drives the second volute to rotate. When the second volute rotates, it meshes with the second gear, driving the second gear to rotate. When the second gear rotates, it drives the third volute to rotate synchronously. The third volute drives the cutting structure, and the cutting structure cuts the reinforcing bar, thus completing the cutting operation.

[0018] After cutting, the rebar falls off, and one end of the rebar is no longer in contact with the extrusion structure. At this time, the extrusion structure resets and moves, driving the drive shaft to reset and move synchronously. After the drive shaft resets and moves to the initial state, the second locking block disengages from the second locking slot and no longer drives the cutting structure. At the same time, the first locking block re-enters the first locking slot and drives the conveying roller again. The rebar is moved by the telescopic roller, which facilitates the cutting of the next section of the rebar and further improves the ease of cutting.

[0019] Specifically, the extrusion structure includes a sliding groove on the upper surface of the main body, a first sliding rod slidably connected in the sliding groove, an extrusion rod detachably connected to the end of the first sliding rod away from the sliding groove, the extrusion rod extruding and contacting one end of the reinforcing bar, and a return spring fixedly connected between the end of the first sliding rod away from the extrusion rod and the inner wall of the sliding groove.

[0020] The upper surface of the first sliding rod is provided with a second sliding rod, the second sliding rod is fixedly connected to the drive shaft, and one end of the second sliding rod is detachably connected to a steel cable, the other end of the steel cable passes around the guide wheel and is connected to the cutting structure.

[0021] By adopting the above technical solution, after the conveying roller moves the steel bar to a certain position, one end of the steel bar is pressed into contact with the extrusion rod, which in turn moves the extrusion rod. When the extrusion rod moves, it drives the first sliding rod to move synchronously. When the first sliding rod moves, it slides into the sliding groove and drives the second sliding rod to move synchronously. When the second sliding rod moves, it drives the drive shaft to move synchronously. When the first sliding rod moves to a certain position, the second sliding rod drives the drive shaft to move to a certain position. At this time, the first locking block disengages from the first locking groove, and the rotation of the conveying roller is turned off. The movement of the second sliding rod drives the steel cable to move, and the cutting structure moves downwards by its own weight. At the same time, the second locking block moves into the second locking groove and drives the cutting structure to work, and the cutting structure performs the cutting operation on the steel bar.

[0022] After the rebar is cut, it falls to the ground and is no longer in contact with the extrusion structure. The return spring then moves the first sliding rod back to its original position, simultaneously moving the second sliding rod and the extrusion rod. Once the first sliding rod is back to its initial position, the second sliding rod moves the drive shaft and steel cable. The steel cable moves the cutting structure upwards, facilitating the subsequent conveyor roller to move the steel pipe and perform the next cut. Simultaneously, after the drive shaft is back to its initial position, the second locking block disengages from the second locking slot, while the first locking block moves into the first locking slot, driving the conveyor roller to rotate again. This facilitates the next cut, improving both the convenience and safety of the cutting process.

[0023] Specifically, the cutting structure includes a movable plate installed inside the cavity, on which a first shaft and a second shaft are rotatably connected. The first shaft is coaxially connected to a first pulley and a third gear, and the third gear meshes with a third spiral gear for transmission.

[0024] One end of the second shaft passes through the movable plate and is fixedly connected to a cutting blade. The end of the second shaft away from the cutting blade is fixedly connected to a second pulley. The second pulley and the first pulley are driven by a second transmission belt.

[0025] The end of the steel cable away from the second sliding rod is detachably connected to the upper end of the moving plate. The main body is provided with a damping structure, and one side of the moving plate is fixedly connected to the damping structure.

[0026] By adopting the above technical solution, when the second card block enters the second card slot, it drives the second volute to rotate. When the second volute rotates, it meshes with the second gear, driving the second gear to rotate. When the second gear rotates, it drives the third volute to rotate synchronously. The third volute meshes with the third gear and drives the first shaft to rotate. When the first shaft rotates, it drives the second pulley to rotate through the first pulley and the second transmission belt. When the second pulley rotates, it drives the cutting blade to rotate, and the cutting blade performs the cutting operation on the steel bar.

[0027] After the cutting is completed, the first sliding rod is reset and moved by the reset spring. When the first sliding rod is reset and moved, it drives the second sliding rod to reset and move. When the second sliding rod is reset and moved, it drives the steel cable to move. The steel cable drives the moving plate to move up. When the moving plate moves up, it drives the cutting blade to move up synchronously. This makes it easier to restore the cut structure to its initial state and facilitates the subsequent cutting of the next section of the steel bar.

[0028] The damping structure prevents the moving plate from falling too quickly, ensuring that the cutting blade can only contact the steel bar for cutting after the steel bar and the main body have stopped moving relative to each other. At the same time, the damping structure can improve the movement stability of the moving plate and the cutting blade.

[0029] Specifically, the damping structure includes a mounting groove, which is vertically formed on the inner wall of the main body. A damping rod is fixedly connected in the mounting groove, and the upper end of the damping rod is fixedly connected to the lower surface of the moving plate.

[0030] By adopting the above technical solution, when the extrusion rod drives the first sliding rod to move, it drives the second sliding rod to move synchronously. When the second sliding rod moves, the steel cable moves, and the moving plate will move downwards by its own weight. At this time, the damping rod can improve the movement stability of the moving plate and the cutting blade, prevent the moving plate from falling rapidly, and ensure that the cutting blade can contact the steel bar to perform cutting work only after the steel bar and the main body stop moving relative to each other.

[0031] Specifically, one end of the first sliding rod passes through the extrusion rod and is slidably connected to the extrusion rod. A locking bolt is threaded onto the side of the extrusion rod, and the locking bolt is in extrusive contact with the side of the first sliding rod.

[0032] By adopting the above technical solution, when it is necessary to adjust the cutting length of the reinforcing bar, the cutting length is adjusted by relying on the sliding connection between the extrusion rod and the first sliding rod, and the extrusion rod and the first sliding rod are fixed by relying on the locking bolt, so as to adjust it according to the actual use.

[0033] Specifically, the main body is fixedly connected to anti-slip handles on both sides near the slot.

[0034] By adopting the above technical solution, the non-slip handle can improve the mobility and flexibility of the main body, further enhancing the ease of use of the present invention.

[0035] The beneficial effects of this invention are:

[0036] (1) The steel bar processing fixed length segment cutting device of the present invention passes the steel bar to be cut through the slot and moves the steel bar to be cut by means of the conveying roller. When the steel bar moves to a certain position, one end of the steel bar is pressed and contacted by the extrusion rod, and drives the first sliding rod to move. When the first sliding rod moves to a certain position, the first locking block disengages from the first locking groove. At this time, the conveying roller no longer drives the steel bar to move, thereby determining the length of the steel bar to be cut and facilitating subsequent cutting, thus improving the convenience of cutting the steel bar.

[0037] (2) The fixed-length segmented cutting device for steel bar processing described in this invention, when the conveying roller no longer drives the steel bar to move, the second clamping block corresponds to the second clamping groove and drives the cutting structure. The steel bar is cut by the cutting structure. After the cutting is completed, the steel bar falls off. At this time, one end of the steel bar is no longer in contact with the extrusion rod. The second clamping block is disengaged from the second clamping groove by the reset effect of the reset spring, the cutting structure is closed, and the conveying roller is driven again. The steel bar to be cut is continued to be conveyed by the conveying roller and the next segmented cutting operation is carried out. This improves the convenience of cutting steel bars and makes it easier to improve the flexibility of use according to the actual use environment.

[0038] (3) The fixed-length segmented cutting device for steel bar processing described in this invention relies on conveying rollers to transport steel bars and facilitate subsequent cutting. When the steel bar specifications are large, the conveying rollers cannot drive the steel bar to move. At this time, the main body is driven to move by the action of several sets of rollers, which facilitates the cutting operation of the steel bar. In this way, the convenience and flexibility of steel bar cutting can be improved according to the actual use. Attached Figure Description

[0055] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0056] To facilitate the segmented cutting of reinforcing bars and improve the ease of cutting, as one embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 8 As shown, the present invention provides a fixed-length segmented cutting device for steel bar processing, comprising a main body 1, a plurality of rollers 2 at the bottom of the main body 1, and a through slot 3 inside the main body 1, the slot 3 being horizontally arranged, through which the steel bar passes.

[0057] The slot 3 is provided with a clamping and conveying structure and a cutting structure. The top of the main body 1 is provided with an adjustable driving structure, which is used to drive the clamping and conveying structure or the cutting structure. The top of the main body 1 is provided with a pressing structure on the side away from the driving structure, which is used to adjust the adjustable driving structure.

[0058] When in use, when it is necessary to cut the steel bar, the steel bar to be cut is passed through the slot 3. The adjustable drive structure drives the clamping and conveying structure, and the clamping and conveying structure drives the steel bar to be cut to move. When the steel bar moves to a certain position, one end of the steel bar is pressed and contacted with the extrusion structure, and the extrusion structure is moved. When the extrusion structure moves to a certain position, the adjustable drive structure no longer drives the clamping and conveying structure to work, thereby determining the length of the steel bar to be cut.

[0059] When the adjustable drive structure stops driving the clamping and conveying structure, it drives the cutting structure to cut the steel bar. After cutting, one end of the steel bar is no longer in contact with the extrusion structure. The reset of the extrusion structure causes the adjustable drive structure to stop driving the cutting structure. At the same time, the adjustable drive structure drives the clamping and conveying structure again and continues to convey the steel bar to be cut, and performs the next segmented cutting operation. This improves the convenience of cutting steel bars and enhances the flexibility of use according to the actual usage environment.

[0060] It should be noted that when the steel bars to be cut are large, the clamping and conveying structure cannot drive the steel bars to move. In this case, the main body 1 is driven to move by several sets of rollers 2 at the bottom of the main body 1. After the main body 1 moves to a certain position, the cutting structure is driven to cut the steel bars. This makes it easier to automatically adjust the cutting method according to the actual specifications of the steel bars, and further improve the convenience of cutting.

[0061] To facilitate the transport of the steel bars that need to be cut, for example, such as Figure 1 , Figure 2 , Figure 8 As shown, the present invention also includes a clamping and conveying structure comprising a cavity 4 provided inside the main body 1, a first output shaft 5 provided inside the cavity 4, one end of the first output shaft 5 passing through the main body 1 and rotatably connected to the main body 1, and the other end of the first output shaft 5 being fixedly connected to a conveying roller 6.

[0062] The cavity 4 is provided with two sets of second output shafts 7. The second output shafts 7 are located below the first output shaft 5. The two ends of the second output shafts 7 are rotatably connected to elastic brackets 8. The lower end of the elastic brackets 8 is fixedly connected to the bottom of the cavity 4 of the main body 1. An auxiliary roller 9 is fixedly connected to the second output shaft 7. The conveying roller 6 and the auxiliary roller 9 are both rolledly connected to the outside of the steel bar. The adjustable drive structure is used to drive the first output shaft 5 to rotate.

[0063] In use, the steel bar to be cut is passed through the slot 3. At this time, the steel bar is located between the conveying roller 6 and the two sets of auxiliary rollers 9. The first output shaft 5 is driven to rotate by the adjustable drive structure. When the first output shaft 5 rotates, it drives the conveying roller 6 to rotate. The conveying roller 6 is used to convey the steel bar to be cut. At the same time, the two sets of auxiliary rollers 9 can improve the stability of the steel bar conveying and facilitate the segmented cutting of the steel bar after it is conveyed to a certain position. The elastic bracket 8 can be used to clamp steel bars of different specifications to ensure the stability of the steel bar conveying.

[0064] To facilitate the cutting of reinforcing bars, for example, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 11 As shown, the present invention further includes an adjustable drive structure comprising a drive motor 10 fixedly mounted on the upper surface of the main body 1. The output end of the drive motor 10 is connected to a telescopic coupling 11. The end of the telescopic coupling 11 away from the drive motor 10 is connected to a drive shaft 12. The upper surface of the main body 1 is provided with a first mounting plate 13 and a second mounting plate 14. A first spiral tooth 15 is rotatably connected to the side of the first mounting plate 13 away from the drive shaft 12. A second spiral tooth 16 is rotatably connected to the side of the second mounting plate 14 near the drive shaft 12. The drive shaft 12 passes sequentially through the first mounting plate 13, the first spiral tooth 15, the second spiral tooth 16, and the second mounting plate 14, and is slidably connected to each of these components. The first spiral tooth 15 and the second spiral tooth 16 are located on one side of...

[0065] The inner walls of the first vortex 15 and the second vortex 16 are respectively provided with a plurality of circumferentially distributed first slots 17 and second slots 18. The outer side of the drive shaft 12 is provided with a first block 19 and a second block 20. The first block 19 is initially located in the first slot 17, and the second block 20 is initially disengaged from the second slot 18. The drive shaft 12 is fixedly connected to the extrusion structure.

[0066] A third output shaft 21 is provided below the first spiral tooth 15. A first gear 22 is fixedly connected to one end of the third output shaft 21. The first gear 22 meshes with the first spiral tooth 15 for transmission. A first pulley 23 is fixedly connected to the other end of the third output shaft 21. A first support plate 24 is rotatably connected to the third output shaft 21. The first support plate 24 is fixedly connected to the upper surface of the main body 1. A second pulley 25 is fixedly connected to the end of the first output shaft 5 away from the conveying roller 6. The first pulley 23 and the second pulley 25 are driven by a first transmission belt 26.

[0067] A third volute 27 is horizontally arranged on one side of the second volute 16. The lower end of the third volute 27 passes through the main body 1 and meshes with the cutting structure for transmission. A second gear 28 is fixedly connected to the upper end of the third volute 27. The second gear 28 meshes with the second volute 16 for transmission. A second support plate 29 is rotatably connected to the side of the second gear 28 away from the third volute 27. The second support plate 29 is fixedly connected to the upper surface of the main body 1.

[0068] In use, the steel bar to be cut is passed through the slot 3. The drive shaft 12 is driven to rotate by the drive motor 10 and the telescopic coupling 11. When the drive shaft 12 rotates, the first locking block 19 is located in the first locking groove 17 and drives the first spiral tooth 15 to rotate. When the first spiral tooth 15 rotates, it meshes with the first gear 22 and drives the third output shaft 21 to rotate. When the third output shaft 21 rotates, it drives the first pulley 23 to rotate. The first transmission belt 26 drives the second pulley 25 to rotate. When the second pulley 25 rotates, it drives the first output shaft 5 to rotate synchronously, and thus drives the conveying roller 6 to rotate. When the conveying roller 6 rotates, it moves the steel bar, which facilitates the movement of the steel bar to be cut.

[0069] When the reinforcing bar moves to a certain position, one end of the reinforcing bar comes into contact with the extrusion structure and drives the extrusion structure to move. When the extrusion structure moves, it drives the drive shaft 12 to move synchronously. The telescopic coupling 11 can improve the ease of movement of the drive shaft 12. When the drive shaft 12 moves to a certain position, the first locking block 19 disengages from the first locking groove 17. At this time, the conveying roller 6 is no longer driven to rotate, the conveying of the reinforcing bar is turned off, and the cutting length of the reinforcing bar is determined. When the first locking block 19 disengages from the first locking groove 17, the second locking block 20 moves into the second locking groove 18 and drives the second volute 16 to rotate. When the second volute 16 rotates, it meshes with the second gear 28 to drive the second gear 28 to rotate. When the second gear 28 rotates, it drives the third volute 27 to rotate synchronously. The third volute 27 drives the cutting structure, and the cutting structure cuts the reinforcing bar to complete the cutting operation.

[0070] After cutting, the steel bar falls off, and one end of the steel bar is no longer in contact with the extrusion structure. At this time, the extrusion structure resets and moves, driving the drive shaft 12 to reset and move synchronously. After the drive shaft 12 resets and moves to the initial state, the second locking block 20 disengages from the second locking groove 18 and no longer drives the cutting structure. At the same time, the first locking block 19 re-enters the first locking groove 17 and drives the conveying roller 6 again. The steel bar is moved by the telescopic roller, which facilitates the cutting of the next section of the steel bar and further improves the cutting convenience.

[0071] To improve the convenience and safety of cutting, as an example, as one embodiment of the present invention, such as Figure 2 , Figure 3 , Figure 7 , Figure 10 , Figure 11 , Figure 12As shown, the present invention also includes the following: the extrusion structure includes a sliding groove 30 opened on the upper surface of the main body 1, a first sliding rod 31 is slidably connected in the sliding groove 30, an extrusion rod 32 is detachably connected to the end of the first sliding rod 31 away from the sliding groove 30, the extrusion rod 32 is in extrusion contact with one end of the reinforcing bar, and a return spring 33 is fixedly connected between the end of the first sliding rod 31 away from the extrusion rod 32 and the inner wall of the sliding groove 30.

[0072] The upper surface of the first sliding rod 31 is provided with a second sliding rod 34. The second sliding rod 34 is fixedly connected to the drive shaft 12. One end of the second sliding rod 34 is detachably connected to a steel cable 35. The other end of the steel cable 35 passes around the guide wheel 36 and is connected to the cutting structure.

[0073] In use, the conveying roller 6 drives the steel bar to a certain position, and one end of the steel bar is pressed into contact with the extrusion rod 32, which in turn drives the extrusion rod 32 to move. When the extrusion rod 32 moves, it drives the first sliding rod 31 to move synchronously. When the first sliding rod 31 moves, it slides into the sliding groove 30 and drives the second sliding rod 34 to move synchronously. When the second sliding rod 34 moves, it drives the drive shaft 12 to move synchronously. When the first sliding rod 31 moves to a certain position, the second sliding rod 34 drives the drive shaft 12 to move to a certain position. At this time, the first locking block 19 disengages from the first locking groove 17, and the rotation of the conveying roller 6 is turned off. The movement of the second sliding rod 34 drives the steel cable 35 to move, and the cutting structure moves downward by its own weight. At the same time, the second locking block 20 moves into the second locking groove 18 and drives the cutting structure to work, and the cutting structure cuts the steel bar.

[0074] After the rebar is cut, it falls off and is no longer in contact with the extrusion structure. The rebar is then reset by the reset effect of the return spring 33, which moves the first sliding rod 31 back to its original position. When the first sliding rod 31 resets, it moves the second sliding rod 34 and the extrusion rod 32 back to their original positions simultaneously. When the first sliding rod 31 resets to its initial position, the second sliding rod 34 moves the drive shaft 12 and the steel cable 35. When the steel cable 35 moves, it moves the cutting structure upward, making it easier for the subsequent conveying roller 6 to move the steel pipe and perform the next section of cutting. At the same time, after the drive shaft 12 resets to its initial position, the second locking block 20 disengages from the second locking groove 18, and the first locking block 19 moves into the first locking groove 17, driving the conveying roller 6 to rotate again. This facilitates the next section of cutting and improves the convenience and safety of cutting.

[0075] For example, such as Figure 8 , Figure 9 , Figure 13As shown, the present invention also includes a cutting structure comprising a movable plate 37 installed inside the cavity 4, on which a first shaft 38 and a second shaft 39 are rotatably connected. The first shaft 38 is coaxially connected to a first pulley 40 and a third gear 41, and the third gear 41 meshes with a third spiral gear 27 for transmission.

[0076] One end of the second shaft 39 passes through the movable plate 37 and is fixedly connected to the cutting blade 42. The other end of the second shaft 39 away from the cutting blade 42 is fixedly connected to the second pulley 43. The second pulley 43 and the first pulley 40 are driven by the second transmission belt 49.

[0077] The end of the steel cable 35 away from the second sliding rod 34 is detachably connected to the upper end of the moving plate 37. The main body 1 is provided with a damping structure, and one side of the moving plate 37 is fixedly connected to the damping structure.

[0078] When in use, when the second card block 20 enters the second card slot 18, it drives the second volute 16 to rotate. When the second volute 16 rotates, it meshes with the second gear 28, driving the second gear 28 to rotate. When the second gear 28 rotates, it drives the third volute 27 to rotate synchronously. The third volute 27 meshes with the third gear 41, driving the first shaft 38 to rotate. When the first shaft 38 rotates, it drives the second pulley 43 to rotate through the first pulley 40 and the second transmission belt 49. When the second pulley 43 rotates, it drives the cutting blade 42 to rotate, and the cutting blade 42 is used to cut the steel bar.

[0079] After the cutting is completed, the first sliding rod 31 is reset and moved by the reset spring 33. When the first sliding rod 31 is reset and moved, it drives the second sliding rod 34 to reset and move. When the second sliding rod 34 is reset and moved, it drives the steel cable 35 to move. The steel cable 35 drives the moving plate 37 to move upward. When the moving plate 37 moves upward, it drives the cutting blade 42 to move upward synchronously. This makes it easier to restore the cutting structure to the initial state and facilitate the subsequent cutting of the next section of the steel bar.

[0080] The damping structure prevents the moving plate 37 from falling too quickly, ensuring that the cutting blade 42 can only contact the steel bar for cutting after the steel bar and the main body 1 have stopped moving relative to each other. At the same time, the damping structure can improve the movement stability of the moving plate 37 and the cutting blade 42.

[0081] To improve the movement stability of the moving plate 37 and the cutting blade 42, for example, such as Figure 8 , Figure 9 As shown, the present invention also includes a damping structure comprising a mounting groove 44, the mounting groove 44 being vertically formed on the inner wall of the main body 1, a damping rod 45 being fixedly connected in the mounting groove 44, and the upper end of the damping rod 45 being fixedly connected to the lower surface of the moving plate 37.

[0082] When in use, when the pressing rod 32 moves the first sliding rod 31, it drives the second sliding rod 34 to move synchronously. When the second sliding rod 34 moves, the steel cable 35 moves, and at the same time, the moving plate 37 moves downward by its own weight. At this time, the damping rod 45 can improve the movement stability of the moving plate 37 and the cutting blade 42, prevent the moving plate 37 from falling quickly, and ensure that the cutting blade 42 can contact the steel bar to perform cutting work only after the steel bar and the main body 1 stop moving relative to each other.

[0083] To adjust the cutting length, for example, such as Figure 14 As shown, the present invention further includes a first sliding rod 31, one end of which passes through the extrusion rod 32 and is slidably connected to the extrusion rod 32, and a locking bolt 46 is threadedly connected to the side of the extrusion rod 32, and the locking bolt 46 is in extrusion contact with the side of the first sliding rod 31.

[0084] When it is necessary to adjust the cutting length of the steel bar during use, the cutting length is adjusted by relying on the sliding connection between the extrusion rod 32 and the first sliding rod 31, and the extrusion rod 32 and the first sliding rod 31 are fixed by relying on the locking bolt 46, so as to adjust it according to the actual use.

[0085] For example, such as Figure 1 As shown, the present invention also includes anti-slip handles 47 fixedly connected to both sides of the main body 1 near the slot 3.

[0086] When in use, the non-slip handle 47 can improve the mobility and flexibility of the main body 1, further enhancing the ease of use of the present invention.

[0087] In use, the reinforcing bar to be cut is passed through the slot 3. The drive motor 10 and the telescopic coupling 11 drive the drive shaft 12 to rotate. When the drive shaft 12 rotates, the first locking block 19 is located in the first locking groove 17 and drives the first spiral tooth 15 to rotate. When the first spiral tooth 15 rotates, it meshes with the first gear 22 and drives the third output shaft 21 to rotate. When the third output shaft 21 rotates, it drives the first pulley 23 to rotate. The first transmission belt 26 drives the second pulley 25 to rotate. When the second pulley 25 rotates, it drives the first output shaft 5 to rotate synchronously, and thus drives the conveying roller 6 to rotate. When the conveying roller 6 rotates, it moves the reinforcing bar, which facilitates the movement of the reinforcing bar to be cut.

[0088] When the steel bar moves to a certain position, one end of the steel bar is pressed into contact with the extrusion rod 32, which in turn drives the extrusion rod 32 to move. When the extrusion rod 32 moves, it drives the first sliding rod 31 to move synchronously. When the first sliding rod 31 moves, it slides into the sliding groove 30 and drives the second sliding rod 34 to move synchronously. When the second sliding rod 34 moves, it drives the drive shaft 12 to move synchronously. When the first sliding rod 31 moves to a certain position, it drives the drive shaft 12 to move to a certain position by relying on the second sliding rod 34. At this time, the first locking block 19 disengages from the first locking groove 17, and the rotation of the conveying roller 6 is turned off.

[0089] The movement of the second sliding rod 34 drives the steel cable 35 to move, and the cutting structure moves downwards by its own weight. At the same time, the second locking block 20 moves into the second locking slot 18. When the second locking block 20 enters the second locking slot 18, it drives the second volute 16 to rotate. When the second volute 16 rotates, it meshes with the second gear 28, driving the second gear 28 to rotate. When the second gear 28 rotates, it drives the third volute 27 to rotate synchronously. The third volute 27 meshes with the third gear 41, driving the first shaft 38 to rotate. When the first shaft 38 rotates, it drives the second pulley 43 to rotate through the first pulley 40 and the second transmission belt 49. When the second pulley 43 rotates, it drives the cutting blade 42 to rotate, and the cutting blade 42 performs the cutting operation on the steel bar.

[0090] After the rebar is cut, it falls off. At this time, the rebar is no longer in contact with the compression rod 32. The first sliding rod 31 is reset and moved by the reset spring 33. When the first sliding rod 31 is reset and moved, it drives the second sliding rod 34 to reset and move. When the second sliding rod 34 is reset and moved, it drives the steel cable 35 to move. The steel cable 35 drives the moving plate 37 to move upward. When the moving plate 37 moves upward, it drives the cutting blade 42 to move upward synchronously. This makes it easier to restore the cutting structure to the initial state and facilitate the subsequent cutting of the next section of the rebar.

[0091] After the second sliding rod 34 drives the drive shaft 12 to reset and move to the initial state, the second locking block 20 disengages from the second locking slot 18, while the first locking block 19 moves into the first locking slot 17 and drives the conveying roller 6 to rotate again, thereby facilitating the next segment of cutting and improving the convenience and safety of cutting.

[0092] When it is necessary to adjust the cutting length of the reinforcing bar, the cutting length is adjusted by the sliding connection between the extrusion rod 32 and the first sliding rod 31, and the extrusion rod 32 and the first sliding rod 31 are fixed by the locking bolt 46, so as to adjust it according to the actual use. The anti-slip handle 47 can improve the mobility and flexibility of the main body 1, and further improve the ease of use of the present invention.
