Description

Technical Field

[0001] The present invention relates to the technical field of steel bar cutting, and more specifically, it relates to a steel bar cutting device for preventing jumping and its cutting method. Background Art

[0002] Steel bars, also known as steel for reinforced concrete, are a commonly used steel product in the construction and engineering fields. They are mainly used to reinforce concrete structures, improve their bearing capacity and durability. Steel bars are usually made of carbon steel, which is an iron-carbon alloy material containing iron elements, and iron has magnetism. Under the action of an external magnetic field, the iron atoms in carbon steel will be attracted by the gravitational force and interact with the magnet.

[0003] Since different building structures and components require steel bars of different lengths to meet the design requirements, it is necessary to cut the standard-length steel bars according to actual needs. Some steel bars need to be bent before cutting to adapt to different structural shapes. The bending of steel bars is very important for ensuring the coordinated force between the steel bars and the concrete. Especially in places where anchoring is required, such as the joints of beams and columns, bending can provide the necessary anchoring length to ensure the stability and safety of the structure.

[0004] In the existing steel bar cutting, one end of the steel bar is manually held, and the other end is cut. Since some steel bars have too large a diameter or multiple steel bars are cut simultaneously, the cross-sectional area of the large-diameter steel bar is large, and the mass of multiple steel bars is too large. Therefore, during cutting, they have greater inertia and momentum. When held by personnel, the fixed force is insufficient, and the steel bar will jump. The jumping of the steel bar will not only cause impact damage to the hands of the personnel, but also lead to inaccurate cutting dimensions or uneven ends of the cut steel bars, affecting subsequent processing and use.

[0005] Therefore, it is necessary to design a steel bar cutting device with good anti-jumping and positioning and clamping effects to improve the above existing technical problems. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a steel bar cutting device for preventing jumping and its cutting method.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A steel bar cutting device for preventing jumping, including a fixed frame and a workbench arranged on one side of the fixed frame. A cutting mechanism for cutting the steel bar is arranged on the upper side of the fixed frame. A transmission mechanism for driving the cutting mechanism is arranged on one side of the cutting mechanism. An alignment mechanism for arranging and limiting multiple steel bars is arranged on the upper side of the workbench. A positioning and clamping mechanism for clamping steel bars with different bending angles is arranged on the upper side of the alignment mechanism.

[0008] The present invention is further configured as follows: The positioning and clamping mechanism includes two support plates fixedly connected to the upper side of the workbench. A first slide rail is fixedly connected to the upper sides of the two support plates. The sliding end of the first slide rail is fixedly connected to a second slide rail. The sliding end of the second slide rail is fixedly connected to a U-shaped positioning plate.

[0010] The present invention is further configured as follows: A database and a judgment module are provided inside the camera.

The judgment module is used to identify the bending angle of the steel bar and classify the bent steel bars into three types: acute-angle steel bars, right-angle steel bars, and obtuse-angle steel bars according to the bending angle of the steel bar.

[0011] The present invention is further configured as follows: The arranging mechanism includes a fixing plate fixedly connected to the upper side of the workbench.

The output end of the third air cylinder is fixedly connected to a first clamping plate. A limiting plate is provided on one side of the first clamping plate and is fixedly connected to the fixing plate. A fifth motor is fixedly connected to one side of the limiting plate.

[0012] The present invention is further configured as follows: A first electromagnetic suction plate is provided on one side of the first clamping plate. The output end of the fifth motor sequentially penetrates the limiting plate and the first clamping plate, and the output end of the fifth motor is fixedly connected to the first electromagnetic suction plate. An electric slider is provided inside the limiting plate. The electric slider is slidably connected to the fixing plate. A second electromagnetic suction plate is provided on one side of the electric slider. A flattening component for flattening the stacked steel bars is provided inside the fixing plate.

[0013] The present invention is further configured as follows: The flattening component includes a fourth air cylinder fixedly connected to the lower side of the workbench. A first slider is slidably connected inside the fixing plate. The output end of the fourth air cylinder sequentially penetrates the workbench, the fixing plate, and the first slider, and the output end of the fourth air cylinder is fixedly connected to a second slider. A third rotating shaft and a fourth rotating shaft are respectively rotatably connected inside the first slider. A first opening plate and a second opening plate are respectively fixedly connected to the outer sides of the third rotating shaft and the fourth rotating shaft. The lower ends of the first opening plate and the second opening plate are both inclined surfaces.

[0014] The present invention is further configured such that when the judgment module recognizes and determines the type of bent steel bars, the output ends of the third motor and the fourth motor rotate to control the arc-shaped clamping plates to rotate, so that the arc-shaped grooves in the arc-shaped clamping plates are parallel to one end of the bent steel bars for positioning and clamping.

[0015] The present invention is further configured such that the first connecting rod in the cutting mechanism is hinged and driven to the first rotating shaft in the transmission mechanism through a positioning block. The other end of the first connecting rod is hinged with a second connecting rod. A guide slide plate is fixedly connected to the upper side of the fixed frame. The second connecting rod is slidably connected inside the guide slide plate. The other end of the second connecting rod is fixedly connected with a first cutting knife.

[0016] The present invention is further configured such that a second cutting knife is provided on one side of the first cutting knife, and a fixed block is fixedly connected to one side of the second cutting knife. The fixed block is fixedly connected to the fixed frame. A collecting assembly for collecting and blocking the cutting waste is provided below the first cutting knife and the second cutting knife.

[0017] The present invention is further configured such that the collecting assembly includes a collecting box fixedly connected to the inside of the fixed frame. A second motor is fixedly connected to one side of the collecting box. A collecting cavity is provided inside the collecting box. A top plate is slidably connected inside the collecting cavity. A U-shaped baffle is slidably connected inside the collecting box.

[0018] The present invention is further configured such that two second rotating shafts are rotatably connected inside the collecting box. One end of each second rotating shaft is fixedly connected with a second gear. The other end of each second rotating shaft is fixedly connected with a third gear. A plurality of tooth columns are fixedly connected to one side of the U-shaped baffle. The tooth columns are meshed and connected with the second rotating shafts. A sliding tooth plate is meshed and connected below each second gear. The sliding tooth plate is fixedly connected with the top plate. The sliding tooth plate is slidably connected with the collecting box. The second motor penetrates through the side wall of the collecting box and is fixedly connected with one of the third gears.

[0019] A method for cutting steel bars to prevent jumping, using the above-mentioned steel bar cutting device for preventing jumping, includes the following steps:

[0020] S1: When it is necessary to cut a plurality of steel bars, the arranging mechanism arranges a plurality of straight steel bars into a vertical and horizontal state, and limits and conveys them.

[0021] S2: When it is necessary to cut a bent steel bar, the camera photographs the bending angle of the bent steel bar, judges the bending degree of the steel bar, stands up or lies down the bent steel bar to determine the correct placement method, thereby controlling the third motor and the fourth motor to control the two arc-shaped clamping plates to rotate different angles, and further accurately clamping steel bars with different bending angles.

[0022] S3: When the transmission mechanism controls the first cutting tool to move closer to the second cutting tool, the steel bar between the first cutting tool and the second cutting tool is cut off.

[0023] S4: When the collection component cuts, it collects the cut steel bar waste. When cutting multiple steel bars or large-diameter steel bars, it switches to the material-blocking mode to block the ejected flying materials. When cutting a single small-diameter steel bar, it switches to the normal cutting and splitting mode, no longer blocks the materials, and indirectly pushes the flying materials blocked in the previous material-blocking mode.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The bending angle of the bent steel bar is detected and photographed by the camera, and the bending degree of the steel bar is judged, so as to stand up or lay down the bent steel bar, determine the correct placement method, and control the third motor and the fourth motor to control the two arc clamping plates to rotate different angles, so as to accurately clamp steel bars with different bending angles, so that steel bars with different bending angles are automatically clamped and positioned during cutting, effectively preventing the phenomenon of jumping of the bent steel bar during cutting.

[0026] 2. Before cutting, the three horizontally placed steel bars are arranged, so that the three horizontally placed steel bars are arranged in a horizontal and vertical placement, and the three horizontally and vertically placed steel bars are limited and conveyed, effectively preventing the steel bars from falling before cutting and squeezing the steel bars in the same row during cutting, causing damage to the steel bars. And when the three steel bars are stacked, the paving component can automatically pave the stacked three steel bars into a horizontally placed state, effectively preventing the phenomenon that the stacked three steel bars cannot be attracted by the first electromagnetic suction plate for turning over.

[0027] 3. When cutting steel bars with a diameter and strength exceeding the specified value, the second gear and the third gear are rotated by the rotation of the output end of the second motor, so as to drive the U-shaped baffle and the top plate to move respectively, effectively blocking the cut materials that bounce the steel bar and falling into the interior of the collection box. And when the top plate returns to its original position, it indirectly drives the cut materials on the right side of the collection cavity to transfer to the left side of the collection cavity, thereby indirectly concentrating and stacking all the cut materials, preventing too much flying materials from accumulating on the right side of the collection cavity and causing the flying materials to overflow.

Detailed implementation manners

[0042] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0043] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0044] Embodiment 1, please refer to Figures 1-10 , the present invention provides the following technical solution: a steel bar cutting device for preventing jitter, including a fixed frame 1 and a workbench 2 provided on one side of the fixed frame 1. A cutting mechanism 4 for cutting steel bars is provided on the upper side of the fixed frame 1. A transmission mechanism 3 for driving the cutting mechanism 4 is provided on one side of the cutting mechanism 4. An arranging mechanism 6 for arranging and limiting a plurality of steel bars is provided on the upper side of the workbench 2. A positioning and clamping mechanism 5 for clamping steel bars with different bending angles is provided on the upper side of the arranging mechanism 6.

[0045] Please refer to Figure 2 , the transmission mechanism 3 includes a first motor 31 fixedly connected to the inside of the fixed frame 1. The output end of the first motor 31 is fixedly connected with a first roller 32. Three positioning rings 36 are respectively provided in the fixed frame 1 from bottom to top. A first rotating shaft 34 is rotatably connected to the inside of each positioning ring 36. A first gear 35 is fixedly connected to the outside of each first rotating shaft 34. Each first gear 35 is meshed with each other. A second roller 33 is fixedly connected to one side of one of the first rotating shafts 34. The second roller 33 is connected to the first roller 32 by a belt.

[0046] Specifically, the rotation of the output end of the first motor 31 is used to control the rotation of the first roller 32. While the first roller 32 rotates, it drives the second roller 33 to rotate, thereby driving the first gear 35 coaxial with the second roller 33 to rotate. All the mutually meshed first gears 35 rotate, and then drive each first rotating shaft 34 to rotate.

[0047] The cutting mechanism 4 includes a positioning block fixedly connected to the outside of one of the first rotating shafts 34. One side of the positioning block is hinged with a first connecting rod 41. The other end of the first connecting rod 41 is hinged with a second connecting rod 42. The upper side of the fixed frame 1 is fixedly connected with a guide slide plate 43. The second connecting rod 42 is slidably connected to the inside of the guide slide plate 43. The other end of the second connecting rod 42 is fixedly connected with a first cutter 45. A second cutter 46 is provided on one side of the first cutter 45, and a fixed block 47 is fixedly connected to one side of the second cutter 46. The fixed block 47 is fixedly connected to the fixed frame 1. A collecting assembly 44 for collecting and blocking cutting waste is provided below the first cutter 45 and the second cutter 46.

[0048] Specifically, while the first rotating shaft 34 rotates, it drives the positioning block to rotate. The positioning block drives the first connecting rod 41 to rotate, thereby driving the second connecting rod 42 to slide inside the guide slide plate 43, and further controlling the first cutting knife 45 to approach the second cutting knife 46 to cut the steel bar between the first cutting knife 45 and the second cutting knife 46. The steel bar cutting machine driven by an electric motor can provide greater cutting force.

[0049] Please refer to Figure 5 , the positioning and clamping mechanism 5 includes two support plates 52 fixedly connected to the upper side of the workbench 2. The upper sides of the two support plates 52 are fixedly connected with a first slide rail 51. The sliding end of the first slide rail 51 is fixedly connected with a second slide rail 53. The sliding end of the second slide rail 53 is fixedly connected with a U-shaped positioning plate 54. One side of the U-shaped positioning plate 54 is fixedly connected with a camera 55, and the other side of the U-shaped positioning plate 54 is fixedly connected with a third motor 56.

[0050] Inside the U-shaped positioning plate 54, there is a fourth motor 57. The output end of the third motor 56 penetrates the U-shaped positioning plate 54 and is fixedly connected with the fourth motor 57. The output end of the fourth motor 57 is fixedly connected with a first air cylinder 58. The output end of the first air cylinder 58 is fixedly connected with a double-shaft clamping air cylinder 59. Both output ends of the double-shaft clamping air cylinder 59 are fixedly connected with arc-shaped clamping plates, and arc-shaped grooves are provided inside the arc-shaped clamping plates.

[0051] Specifically, please refer to Figure 6 , at position a, when the steel bar is bent into an acute angle, it is the part that the arc-shaped groove of the double-shaft clamping air cylinder 59 needs to clamp. Since it interferes with the fixed block 47, it is erected for cutting. At position b, when the steel bar is bent into a right angle, it is the part that the arc-shaped groove of the double-shaft clamping air cylinder 59 needs to clamp. Since it does not interfere with the fixed block 47, it is laid down for cutting. At position c, when the steel bar is bent into an obtuse angle, it is the part that the arc-shaped groove of the double-shaft clamping air cylinder 59 needs to clamp. Since it does not interfere with the fixed block 47, it is laid down for cutting. The movement of the sliding end of the first slide rail 51 is used to control the movement of the second slide rail 53, and the movement of the sliding end of the second slide rail 53 is used to control the movement of the U-shaped positioning plate 54, so that the arc-shaped clamping plate reaches above one end of the steel bar with each different bending angle.

[0052] The extension of the output end of the first air cylinder 58 is used to control the arc-shaped clamping plate to approach one end of the steel bar with different bending angles. The expansion and contraction of both output ends of the double-shaft clamping air cylinder 59 are used to control the arc-shaped clamping plate to clamp or release one end of the steel bar with different bending angles. The rotation of the output end of the fourth motor 57 is used to control the rotation of the arc-shaped clamping plate, so that the arc-shaped groove can be parallel to one end of the laid-down bent steel bar, and then position and clamp it. The rotation of the output end of the third motor 56 is used to control the rotation of the arc-shaped clamping plate, so that the arc-shaped groove can be parallel to one end of the erected bent steel bar, and then position and clamp it.

[0053] The camera 55 is internally provided with a database and a judgment module, and the database is internally provided with identification photos of different bending angles of steel bars.

[0054] Specifically, the camera 55 is used to take an image of the bent steel bar, compare it with the identification photos of different bending angles of steel bars inside the database, and then the judgment module identifies the bending angle of the steel bar. According to the taken photo of the bent steel bar, the bending angle of the steel bar is classified into three types of bent steel bars: acute-angled steel bars, right-angled steel bars, and obtuse-angled steel bars.

[0055] Figure 5 This is the initial working state of the third motor 56, the fourth motor 57, the first cylinder 58, and the double-shaft clamping cylinder 59.

[0056] When the judgment module determines that the bending angle of the steel bar is acute, as Figure 6 shown at the position a, to prevent the acute-angled steel bar from interfering with the fixed block 47, the external manipulator stands up the acute-angled steel bar and places it between the first cutter 45 and the second cutter 46. The sliding ends of the first slide rail 51 and the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamping plate reaches above one end of the acute-angled steel bar. The output end of the third motor 56 starts to rotate clockwise until the arc groove is parallel to one end of the acute-angled steel bar. The output end of the third motor 56 stops rotating. The output end of the first cylinder 58 extends so that one end of the acute-angled steel bar is located between the two arc grooves. The two output ends of the double-shaft clamping cylinder 59 contract, so as to control the arc clamping plate to clamp and position the standing acute-angled steel bar. After the cutting mechanism 4 cuts the acute-angled steel bar, the positioning and clamping mechanism 5 returns to its original position.

[0057] When the judgment module determines that the bending angle of the steel bar is right-angled, as Figure 6 shown at the position b, the right-angled steel bar will not interfere with the fixed block 47. The external manipulator lays down the right-angled steel bar and places it between the first cutter 45 and the second cutter 46. The sliding ends of the first slide rail 51 and the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamping plate reaches above one end of the acute-angled steel bar. The output end of the fourth motor 57 rotates clockwise by 90 degrees. At this time, the arc groove is parallel to one end of the right-angled steel bar. The output end of the first cylinder 58 extends so that one end of the right-angled steel bar is located between the two arc grooves. The two output ends of the double-shaft clamping cylinder 59 contract, so as to control the arc clamping plate to clamp and position the laid-down right-angled steel bar. After the cutting mechanism 4 cuts the acute-angled steel bar, the positioning and clamping mechanism 5 returns to its original position.

[0058] When the judgment module determines that the bending angle of the steel bar is obtuse, as Figure 6At the position c shown, the obtuse-angle steel bars will not interfere with the fixed block 47. The external manipulator will pour down the obtuse-angle steel bars and place them between the first cutting knife 45 and the second cutting knife 46. The sliding ends of the first slide rail 51 and the second slide rail 53 move to control the movement of the U-shaped positioning plate 54, so that the arc clamping plate reaches above one end of the obtuse-angle steel bar. The output end of the fourth motor 57 starts to rotate clockwise until the arc groove is parallel to one end of the obtuse-angle steel bar. The output end of the fourth motor 57 stops rotating. The output end of the first cylinder 58 extends so that one end of the right-angle steel bar is located between the two arc grooves. The two output ends of the double-shaft clamping cylinder 59 contract, so as to control the arc clamping plate to clamp and position the poured obtuse-angle steel bar. After the cutting mechanism 4 cuts the obtuse-angle steel bar, the positioning and clamping mechanism 5 returns to its original position.

[0059] The bending angle of the bent steel bar is detected and photographed by the camera 55, and the bending degree of the steel bar is judged, so as to stand up or pour down the bent steel bar, determine the correct placement method, and control the third motor 56 and the fourth motor 57 to control the two arc clamping plates to rotate different angles, so as to accurately clamp the steel bars with different bending angles, so that when the steel bars with different bending angles are cut, they are automatically clamped and positioned, effectively preventing the phenomenon of the bent steel bar jumping during cutting.

[0060] Embodiment 2. When cutting multiple steel bars, since there are tool feed gaps left on the side after the steel bars are put in, the steel bars will collapse. The collapsed steel bars will fall to the bottom, resulting in more than one steel bar in each row. At this time, cutting will not only squeeze and deform the steel bars in the same row, but also increase the tool feed stroke of the cutting knife, increase the cutting time of the steel bars, and reduce the cutting efficiency of the steel bars. Therefore, the following structure is designed to solve the above technical problems.

[0061] Please refer to Figures 7-10 , the arranging mechanism 6 includes a fixing plate 61 fixedly connected to the upper side of the workbench 2. A second cylinder 62 and a third cylinder 63 are respectively arranged on both sides of the fixing plate 61. The second cylinder 62 and the third cylinder 63 are both fixedly connected to the workbench 2. The output end of the second cylinder 62 is fixedly connected with a second clamping plate 65, and the output end of the third cylinder 63 is fixedly connected with a first clamping plate 64. A limiting plate 67 is arranged on one side of the first clamping plate 64 and the limiting plate 67 is fixedly connected to the fixing plate 61. A fifth motor 68 is fixedly connected to one side of the limiting plate 67.

[0062] Specifically, the external robotic arm places multiple steel bars above the fixing plate 61.

[0063] In this embodiment, three steel bars are taken as an example. When placing three unstacked steel bars, the output end of the second cylinder 62 extends to control the second clamping plate 65 to approach the first clamping plate 64, and pushes the three steel bars placed on the fixing plate 61, so as to squeeze the three steel bars towards the first clamping plate 64 for convergence.

[0064] When placing three stacked steel bars, the output ends of the second cylinder 62 and the third cylinder 63 extend simultaneously, thereby pushing the stacked steel bars towards the middle of the fixed plate 61, and finally making the three stacked steel bars located above the flattening assembly 66.

[0065] One side of the first clamping plate 64 is provided with a first electromagnetic suction plate. The output end of the fifth motor 68 sequentially penetrates through the limiting plate 67 and the first clamping plate 64, and the output end of the fifth motor 68 is fixedly connected to the first electromagnetic suction plate. An electric slider 69 is arranged inside the limiting plate 67. The electric slider 69 is slidably connected to the fixed plate 61. One side of the electric slider 69 is provided with a second electromagnetic suction plate. Inside the fixed plate 61, there is a flattening assembly 66 for flattening the stacked steel bars.

[0066] Specifically, a motor and rollers are arranged inside the electric slider 69. The motor controls the rollers to rotate, so that the rollers roll inside the fixed plate 61, and further the electric slider 69 slides along the inside of the fixed plate 61. The second electromagnetic suction plate is used to suck the plane of the steel bar, and the first electromagnetic suction plate is used to suck the arc surface of the steel bar.

[0067] After the three steel bars are squeezed towards the first clamping plate 64 and converge, the output end of the second cylinder 62 retracts to drive the second clamping plate 65 to return. The output end of the fifth motor 68 rotates to control the first electromagnetic suction plate to rotate clockwise by 90 degrees, so as to make the first electromagnetic suction plate stick to the arc surface of the steel bar. The first electromagnetic suction plate is turned on to suck the three horizontally arranged steel bars. The output end of the fifth motor 68 rotates to control the first electromagnetic suction plate to rotate counterclockwise by 90 degrees, so as to make the first electromagnetic suction plate return to its original position. At this time, the three horizontally arranged steel bars are driven to rotate, and at this time the three steel bars are horizontally and vertically arranged.

[0068] The output end of the second cylinder 62 extends to drive the second clamping plate 65 to move to limit the three horizontally and vertically arranged steel bars. The first electromagnetic suction plate is turned off and the second electromagnetic suction plate is turned on. The electric slider 69 starts to move. The second electromagnetic suction plate sequentially sucks one end of each steel bar, so as to align one end of each steel bar, and convey the three horizontally and vertically arranged steel bars, and further perform vertical arrangement and cutting of the three steel bars. When cutting, the output end of the second cylinder 62 extends again to clamp the three steel bars. After cutting is completed, the output end of the second cylinder 62 retracts again to limit the three steel bars.

[0069] The tiling component 66 includes a fourth cylinder 661 fixedly connected to the lower side of the workbench 2. A first slider 662 is slidably connected inside the fixed plate 61. The output end of the fourth cylinder 661 sequentially penetrates through the workbench 2, the fixed plate 61, and the first slider 662, and the output end of the fourth cylinder 661 is fixedly connected to a second slider 663. Inside the first slider 662, a third rotating shaft 664 and a fourth rotating shaft 665 are respectively rotatably connected. A first opening plate 666 and a second opening plate 667 are respectively fixedly connected to the outer sides of the third rotating shaft 664 and the fourth rotating shaft 665. The lower ends of the first opening plate 666 and the second opening plate 667 are both inclined planes.

[0070] When three stacked steel bars are located above the tiling component 66, the output end of the fourth cylinder 661 extends to control the second slider 663 to move upward until it abuts against the lower inclined planes of the first opening plate 666 and the second opening plate 667. Since one side of the first opening plate 666 and the second opening plate 667 is limited by the fixed plate 61 and the first opening plate 666 and the second opening plate 667 cannot rotate, they are indirectly driven by the second slider 663 to move upward. The first slider 662 is also driven by the first opening plate 666 and the second opening plate 667 to indirectly move upward. While the first opening plate 666 and the second opening plate 667 move upward, the two steel bars that are close to each other are respectively pushed away to both sides.

[0071] At this time, the distance of pushing away is not enough for the steel bar above the two steel bars to fall. Therefore, the output end of the fourth cylinder 661 continues to extend until the lowest points of the first opening plate 666 and the second opening plate 667 exceed the top surface of the fixed plate 61. At this time, the lower inclined sides of the first opening plate 666 and the second opening plate 667 are squeezed by the second slider 663, and the first opening plate 666 and the second opening plate 667 are driven by the second slider 663 to rotate counterclockwise and clockwise respectively, thereby opening the first opening plate 666 and the second opening plate 667, and further pushing the two steel bars farther respectively. At this time, the distance of pushing away is enough for the steel bar above the two steel bars to fall. The steel bar above falls between the first opening plate 666 and the second opening plate 667, and the first opening plate 666 and the second opening plate 667 support the lower semi-circular arc of the upper steel bar.

[0072] When the output end of the fourth cylinder 661 retracts, it drives the second slider 663 to slide downward. At this time, the first slider 662 is indirectly driven by the second slider 663 to move downward. The first opening plate 666 and the second opening plate 667 are also indirectly driven by the first slider 662 to move downward. One side of the first opening plate 666 and the second opening plate 667 is squeezed by the fixing plate 61. The first opening plate 666 rotates clockwise and the second opening plate 667 rotates counterclockwise, so as to close the first opening plate 666 and the second opening plate 667, and extrude the upper steel bars until the output end of the fourth cylinder 661 completely retracts and the first opening plate 666 and the second opening plate 667 completely return to their positions. At this time, the three steel bars are no longer in a stacked state but in a horizontal and transverse placement state. The arrangement of the subsequent three steel bars has been specifically described in the above technical solution and will not be elaborated here.

[0073] Before cutting, the three horizontally and transversely placed steel bars are arranged so that the three horizontally and transversely placed steel bars are arranged in a horizontal and vertical placement, and the three horizontally and vertically placed steel bars are limited and conveyed, effectively preventing the steel bars from falling before cutting, squeezing the steel bars in the same row during cutting and causing damage to the steel bars. And when the three steel bars are stacked, the paving assembly 66 can automatically pave the stacked three steel bars into a horizontal and transverse placement state, effectively preventing the phenomenon that the stacked three steel bars cannot be attracted by the first electromagnetic suction plate for turning over.

[0074] In the third embodiment, when cutting waste materials of steel bars with a diameter and strength exceeding the specified values, the cutting material will fly due to the overload operation of the machine, so that the waste materials fly everywhere, which is not conducive to the collection of waste materials, and will also fly into the equipment and damage the equipment. And when personnel are near the equipment, the cutting material may fly onto the personnel and cause injury to the personnel, which has great potential safety hazards. Therefore, the following structure is designed to solve the above technical problems.

[0075] Please refer to Figure 3 and Figure 4 As shown in [relevant figure numbers], the collection assembly 44 includes a collection box 441 fixedly connected to the inside of the fixed frame 1. One side of the collection box 441 is fixedly connected with a second motor 442. The inside of the collection box 441 is provided with a collection cavity. A top plate 444 is slidably connected to the inside of the collection cavity, and a U-shaped baffle 443 is slidably connected to the inside of the collection box 441.

[0076] Specifically, the inside of the collection box 441 is used to store the cut waste materials. The rotation of the output end of the second motor 442 is used to control the rotation of the second gear 445 and the third gear 447, so as to drive the U-shaped baffle 443 and the top plate 444 to move respectively.

[0077] Inside the collection box 441, there are two second rotating shafts 446 rotatably connected. One end of each second rotating shaft 446 is fixedly connected to a second gear 445, and the other end of each second rotating shaft 446 is fixedly connected to a third gear 447. A number of tooth columns 449 are fixedly connected to one side of the U-shaped baffle 443. The tooth columns 449 are meshed and connected with the second rotating shaft 446. Below each second gear 445, there is a sliding tooth plate 448 meshed and connected. The sliding tooth plate 448 is fixedly connected to the top plate 444. The sliding tooth plate 448 is slidably connected to the collection box 441. The second motor 442 penetrates the side wall of the collection box 441 and is fixedly connected to one of the third gears 447.

[0078] Specifically, in the initial state, the top plate 444 is located in the middle of the collection cavity.

[0079] When cutting waste of steel bars with a diameter and strength exceeding the specified values, the output end of the second motor 442 starts to rotate clockwise. At this time, the second gear 445 and the third gear 447 are driven to rotate clockwise, the U-shaped baffle 443 is driven to move upward, and the top plate 444 is driven to move to the right until the top plate 444 abuts against the inner wall of the collection cavity. Then the output end of the second motor 442 stops rotating. At this time, the U-shaped baffle 443 rises to the highest position. At this time, the cut material bounces off, and the cut material bounces to one side of the U-shaped baffle 443 and falls into the right side of the collection cavity.

[0080] When all the waste of steel bars with a diameter and strength exceeding the specified values has been cut, to prevent the U-shaped baffle 443 from interfering with the subsequent cutting and splitting of long steel bars, the output end of the second motor 442 starts to rotate counterclockwise. At this time, the second gear 445 and the third gear 447 are driven to rotate counterclockwise, the U-shaped baffle 443 is driven to move downward, and the top plate 444 is driven to move to the left. While the top plate 444 moves to the left, it indirectly drives the cut material on the right side of the collection cavity to be transferred to the left side of the collection cavity, thereby indirectly concentrating and piling up all the cut materials to prevent too much flying material from accumulating on the right side of the collection cavity.

[0081] When cutting steel bars with a diameter and strength exceeding the specified values, by rotating the output end of the second motor 442 to control the rotation of the second gear 445 and the third gear 447, the U-shaped baffle 443 and the top plate 444 are respectively driven to move, effectively blocking the cut material bounced off by the steel bars and making it fall into the inside of the collection box 441. And while the top plate 444 returns to its original position, it indirectly drives the cut material on the right side of the collection cavity to be transferred to the left side of the collection cavity, thereby indirectly concentrating and piling up all the cut materials to prevent too much flying material from accumulating on the right side of the collection cavity and causing the flying material to overflow.

[0082] Embodiment 4, a method for preventing jumping during steel bar cutting, using the above-mentioned steel bar cutting equipment for preventing jumping, includes the following steps:

[0083] S1: When it is necessary to cut multiple steel bars, the arranging mechanism 6 arranges multiple straight steel bars into a vertical and horizontal state, and positions and conveys them.

[0084] The more specific steps of S1 are as follows. S11: When placing three unstacked steel bars, the output end of the second cylinder 62 extends to control the second clamping plate 65 to approach the first clamping plate 64, and pushes the three steel bars placed on the fixed plate 61, so as to squeeze the three steel bars towards the first clamping plate 64 for convergence.

[0085] S12: After the three steel bars are squeezed towards the first clamping plate 64 for convergence, the output end of the second cylinder 62 retracts to drive the second clamping plate 65 to return. The output end of the fifth motor 68 rotates to control the first electromagnetic suction plate to rotate clockwise by 90 degrees, so as to make the first electromagnetic suction plate stick to the arc surface of the steel bar, turn on the first electromagnetic suction plate, and suck the three horizontally placed steel bars. The output end of the fifth motor 68 rotates to control the first electromagnetic suction plate to rotate counterclockwise by 90 degrees, so as to make the first electromagnetic suction plate return. At this time, the three horizontally placed steel bars are driven to rotate, and at this time the three steel bars are horizontally and vertically placed.

[0086] S13: When placing three stacked steel bars, the output ends of the second cylinder 62 and the third cylinder 63 extend simultaneously, so as to push the stacked steel bars towards the middle of the fixed plate 61, and finally make the three stacked steel bars located above the flattening assembly 66.

[0087] S14: The output end of the second cylinder 62 extends to drive the second clamping plate 65 to move to limit the three horizontally and vertically placed steel bars. Turn off the first electromagnetic suction plate and turn on the second electromagnetic suction plate. The electric slider 69 starts to move. The second electromagnetic suction plate successively sucks one end of each steel bar, so as to align one end of each steel bar, and convey the three horizontally and vertically placed steel bars, and then perform vertical arrangement and cutting of the three steel bars. When cutting, the output end of the second cylinder 62 extends again to clamp the three steel bars. After cutting, the output end of the second cylinder 62 retracts again to limit the three steel bars.

[0088] S15: When the three stacked steel bars are located above the flattening assembly 66, the output end of the fourth cylinder 661 extends to control the second slider 663 to move upward until it touches the lower inclined surfaces of the first opening plate 666 and the second opening plate 667. Since one side of the first opening plate 666 and the second opening plate 667 is limited by the fixed plate 61, the first opening plate 666 and the second opening plate 667 cannot rotate, so they are indirectly driven by the second slider 663 to move upward. The first slider 662 is also driven by the first opening plate 666 and the second opening plate 667 to move indirectly upward. While the first opening plate 666 and the second opening plate 667 move upward, they push the two closely adjacent steel bars away from each other to both sides.

[0089] S16: At this time, the pushing distance is not enough for one steel bar above the two steel bars to fall off. Therefore, the output end of the fourth cylinder 661 continues to extend until the lowest points of the first opening plate 666 and the second opening plate 667 exceed the top surface of the fixed plate 61. At this time, the lower inclined sides of the first opening plate 666 and the second opening plate 667 are squeezed by the second slider 663. Driven by the second slider 663, the first opening plate 666 and the second opening plate 667 rotate counterclockwise and clockwise respectively, so as to open the first opening plate 666 and the second opening plate 667, and then push the two steel bars further away respectively. At this time, the pushing distance is enough for one steel bar above the two steel bars to fall. One steel bar above falls between the first opening plate 666 and the second opening plate 667, and the first opening plate 666 and the second opening plate 667 support the lower semi-circular arc of the upper steel bar.

[0090] S17: The output end of the fourth cylinder 661 retracts to drive the second slider 663 to slide downward. At this time, the first slider 662 is indirectly driven by the second slider 663 to move downward, and the first opening plate 666 and the second opening plate 667 are also indirectly driven by the first slider 662 to move downward. One side of the first opening plate 666 and the second opening plate 667 is squeezed by the fixed plate 61. The first opening plate 666 and the second opening plate 667 rotate clockwise and counterclockwise respectively, so as to close the first opening plate 666 and the second opening plate 667 and squeeze out the upper steel bar until the output end of the fourth cylinder 661 completely retracts and the first opening plate 666 and the second opening plate 667 completely return to their positions. At this time, the three steel bars are no longer in a stacked state but in a horizontal and transverse arrangement state. The arrangement method of the subsequent three steel bars has been specifically described in the above technical solution and will not be elaborated here.

[0091] S2: When cutting the bent steel bars, the camera 55 takes pictures of the bending angles of the bent steel bars, judges the bending degree of the steel bars, stands up or lies down the bent steel bars to determine the correct placement method, and then controls the third motor 56 and the fourth motor 57 to control the two arc-shaped clamping plates to rotate different angles, so as to accurately clamp the steel bars with different bending angles.

[0092] The more specific steps of S2 are as follows. S21: The camera 55 takes pictures of the bent steel bars and compares them with the recognition pictures of different bending angles of steel bars in the internal database. Then, it recognizes the bending angles of the steel bars, and according to the taken pictures of the bent steel bars, classifies the bending angles of the steel bars into three types of bent steel bars: acute-angle steel bars, right-angle steel bars, and obtuse-angle steel bars.

[0093] S22: When the judgment module determines that the bending angle of the steel bar is an acute angle, to prevent the acute-angled steel bar from interfering with the fixed block 47, the external manipulator stands up the acute-angled steel bar and places it between the first cutter 45 and the second cutter 46. The sliding ends of the first slide rail 51 and the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamping plate reaches above one end of the acute-angled steel bar. The output end of the third motor 56 starts to rotate clockwise until the arc groove is parallel to one end of the acute-angled steel bar, and then the output end of the third motor 56 stops rotating. The output end of the first cylinder 58 extends so that one end of the acute-angled steel bar is located between the two arc grooves. The two output ends of the double-shaft clamping cylinder 59 contract, thereby controlling the arc clamping plate to clamp and position the standing acute-angled steel bar. After the cutting mechanism 4 cuts the acute-angled steel bar, the positioning and clamping mechanism 5 returns to its original position.

[0094] S23: When the judgment module determines that the bending angle of the steel bar is a right angle, the right-angled steel bar will not interfere with the fixed block 47. The external manipulator lays down the right-angled steel bar and places it between the first cutter 45 and the second cutter 46. The sliding ends of the first slide rail 51 and the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamping plate reaches above one end of the right-angled steel bar. The output end of the fourth motor 57 rotates clockwise by 90 degrees. At this time, the arc groove is parallel to one end of the right-angled steel bar. The output end of the first cylinder 58 extends so that one end of the right-angled steel bar is located between the two arc grooves. The two output ends of the double-shaft clamping cylinder 59 contract, thereby controlling the arc clamping plate to clamp and position the laid-down right-angled steel bar. After the cutting mechanism 4 cuts the acute-angled steel bar, the positioning and clamping mechanism 5 returns to its original position.

[0095] S24: When the judgment module determines that the bending angle of the steel bar is an obtuse angle, the obtuse-angled steel bar will not interfere with the fixed block 47. The external manipulator lays down the obtuse-angled steel bar and places it between the first cutter 45 and the second cutter 46. The sliding ends of the first slide rail 51 and the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamping plate reaches above one end of the obtuse-angled steel bar. The output end of the fourth motor 57 starts to rotate clockwise until the arc groove is parallel to one end of the obtuse-angled steel bar, and then the output end of the fourth motor 57 stops rotating. The output end of the first cylinder 58 extends so that one end of the right-angled steel bar is located between the two arc grooves. The two output ends of the double-shaft clamping cylinder 59 contract, thereby controlling the arc clamping plate to clamp and position the laid-down obtuse-angled steel bar. After the cutting mechanism 4 cuts the obtuse-angled steel bar, the positioning and clamping mechanism 5 returns to its original position.

[0096] S3: When the transmission mechanism 3 controls the first cutter 45 to move closer to the second cutter 46, the steel bar between the first cutter 45 and the second cutter 46 is cut off.

[0097] S4: When the collecting component 44 cuts off, it collects the cut steel bar waste. When cutting multiple steel bars or large-diameter steel bars, it switches to the material blocking mode to block the ejected flying materials. When cutting and separating individual small-diameter steel bars, it switches to the normal cutting and separating mode, no longer blocks the materials, and indirectly pushes the flying materials blocked in the previous material blocking mode.

[0098] The more specific steps of S4 are as follows. S41: When cutting off waste materials of steel bars with a diameter and strength exceeding the specified values, the output end of the second motor 442 starts to rotate clockwise. At this time, the second gear 445 and the third gear 447 are driven to rotate clockwise, the U-shaped baffle 443 is driven to move upward, and the top plate 444 is driven to move to the right until the top plate 444 abuts against the inner wall of the collecting cavity. Then the output end of the second motor 442 stops rotating. At this time, the U-shaped baffle 443 rises to the highest position. At this time, the cut material bounces off, and the cut material bounces to one side of the U-shaped baffle 443 and falls into the right side of the collecting cavity.

[0099] S42: After cutting off waste materials of all steel bars with a diameter and strength exceeding the specified values, to prevent the U-shaped baffle 443 from interfering with the subsequent cutting and separation of long steel bars, the output end of the second motor 442 starts to rotate counterclockwise. At this time, the second gear 445 and the third gear 447 are driven to rotate counterclockwise, the U-shaped baffle 443 is driven to move downward, and the top plate 444 is driven to move to the left. While the top plate 444 moves to the left, it indirectly drives the cut materials on the right side of the collecting cavity to transfer to the left side of the collecting cavity, thereby indirectly concentrating and piling up all the cut materials to prevent excessive flying materials from accumulating on the right side of the collecting cavity.
