Description

Technical Field

[0001] This invention relates to the field of rebar cutting technology, and more specifically, to a rebar cutting device and method for preventing jumping. Background Art

[0002] Reinforcing steel, also known as steel for reinforced concrete, is a commonly used steel product in the construction and engineering fields. It is primarily used to reinforce concrete structures, improving their load-bearing capacity and durability. Reinforcing steel is typically made of carbon steel, an iron-carbon alloy containing iron, which is magnetic. Under the influence of an external magnetic field, the iron atoms in the carbon steel are attracted by gravity and interact with the magnet.

[0003] Since different building structures and components require steel bars of different lengths to meet design requirements, standard-length steel bars need to be cut according to actual needs. Some steel bars need to be bent before cutting in order to adapt to different structural shapes. Bending steel bars is very important to ensure that the steel bars and concrete work together to bear the load, especially in places where anchorage is required, such as the connection between beams and columns. Bending can provide the necessary anchorage length to ensure the stability and safety of the structure.

[0004] Current methods for cutting reinforcing bars involve manually holding one end of the bar and cutting the other. However, due to the large diameter of some reinforcing bars or the simultaneous cutting of multiple bars, the large diameter bars have a large cross-sectional area and a large mass, resulting in greater inertia and momentum during cutting. When the person holds the bar, the fixing force is insufficient, causing the reinforcing bar to jump. This jumping not only causes impact injuries to the person's hands but also leads to inaccurate cutting dimensions or uneven ends of the cut reinforcing bars, affecting subsequent processing and use.

[0005] Therefore, it is necessary to design a rebar cutting device that prevents rebar from jumping and has a good positioning and clamping effect to improve the above-mentioned technical problems. Summary of the Invention

[0019] A method for cutting steel bars to prevent jumping, using the above-mentioned steel bar cutting device to prevent jumping, comprises the following steps: S1: When multiple steel bars need to be cut, the arranging mechanism arranges multiple straight steel bars into a vertical or horizontal state, and limits and transports them.

[0020] S2: When the bent steel bar needs to be cut, the camera captures the bending angle of the bent steel bar and determines the bending degree of the steel bar, thereby controlling the third motor and the fourth motor to control the two arc clamps to rotate to different angles, thereby accurately clamping the steel bars with different bending angles.

[0021] S3: When the transmission mechanism controls the first cutter to move and approach the second cutter, the steel bar between the first cutter and the second cutter is cut.

[0022] S4: When cutting, the collection component collects the cut steel bar scrap. When cutting multiple steel bars or large-diameter steel bars, it switches to the material blocking mode to block the flying material. When cutting a single small-diameter steel bar, it switches to the normal cutting and segmenting mode, no longer blocking the material, and indirectly pushes the flying material blocked by the previous material blocking mode.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The camera detects and shoots the bending angle of the bent steel bar and determines the bending degree of the steel bar, so as to stand up or fall the bent steel bar, determine the correct placement method, and control the third motor and the fourth motor to control the two arc clamps to rotate to different angles, thereby accurately clamping the steel bars with different bending angles, so that the steel bars with different bending angles can be automatically clamped and positioned when cut, effectively preventing the bent steel bars from jumping when cut.

[0024] 2. Before cutting, the three horizontally placed steel bars are arranged so that they are arranged horizontally and vertically, and the three horizontally and vertically placed steel bars are limited in conveyance, which effectively prevents the steel bars from falling before cutting and squeezing the steel bars in the same row during cutting, causing damage to the steel bars. When the three steel bars are stacked, the flattening component can automatically flatten the stacked three steel bars into a horizontal and horizontal state, effectively preventing the three stacked steel bars from being unable to be sucked by the first electromagnetic suction plate and turned over.

[0025] 3. When cutting steel bars that exceed the specified diameter and strength, the second motor output end is used to control the second gear and the third gear to rotate, thereby driving the U-shaped baffle and the top plate to move respectively, thereby effectively blocking the flying steel bar cuttings and dropping them into the collection box. At the same time as the top plate returns to its position, it indirectly drives the cuttings on the right side of the collection chamber to be transferred to the left side of the collection chamber, thereby indirectly centrally piling up all the cuttings to prevent excessive flying materials from accumulating on the right side of the collection chamber and causing overflow.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] For example 1, please refer to Figure 1-10The present invention provides the following technical solution: a rebar cutting device for preventing jumping, including a fixed frame 1 and a workbench 2 disposed on one side of the fixed frame 1. The upper side of the fixed frame 1 is provided with a cutting mechanism 4 for cutting rebar. The side of the cutting mechanism 4 is provided with a transmission mechanism 3 for driving the cutting mechanism 4. The upper side of the workbench 2 is provided with an arrangement mechanism 6 for arranging and limiting multiple rebars. The upper side of the arrangement mechanism 6 is provided with a positioning and clamping mechanism 5 for clamping rebars with different bending angles.

[0031] Please see Figure 2 The transmission mechanism 3 includes a first motor 31 fixedly connected inside the fixed frame 1. The output end of the first motor 31 is fixedly connected to a first roller 32. The fixed frame 1 has three positioning rings 36 arranged from bottom to top. Each positioning ring 36 has a first rotating shaft 34 connected to it by a bearing. Each first rotating shaft 34 has a first gear 35 fixedly connected to its outer side. Each first gear 35 meshes with each other. One side of one of the first rotating shafts 34 is fixedly connected to a second roller 33, which is connected to the first roller 32 by a belt.

[0032] Specifically, the rotation of the output end of the first motor 31 is used to control the rotation of the first roller 32. When 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, and all the mutually meshed first gears 35 rotate, thereby driving each first rotating shaft 34 to rotate.

[0033] The cutting mechanism 4 includes a positioning block fixedly connected to the outside of one of the first rotating shafts 34. A first connecting rod 41 is hinged to one side of the positioning block, and a second connecting rod 42 is hinged to the other end of the first connecting rod 41. A guide plate 43 is fixedly connected to the upper side of the fixing frame 1. The second connecting rod 42 is slidably connected to the guide plate 43. A first cutter 45 is fixedly connected to the other end of the second connecting rod 42. A second cutter 46 is provided on one side of the first cutter 45, and a fixing block 47 is fixedly connected to one side of the second cutter 46. The fixing block 47 is fixedly connected to the fixing frame 1. A collection assembly 44 for collecting and blocking the cutting waste is provided on the lower side of the first cutter 45 and the second cutter 46.

[0034] Specifically, the first rotating shaft 34 rotates while driving the positioning block to rotate, and the positioning block drives the first connecting rod 41 to rotate, thereby driving the second connecting rod 42 to slide inside the guide slide 43, and then controlling the first cutter 45 to approach the second cutter 46, cutting the steel bars between the first cutter 45 and the second cutter 46. The motor-driven steel bar cutting machine can provide greater cutting force.

[0035] See also Figure 5The 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 to the first slide rail 51, the sliding end of the first slide rail 51 is fixedly connected to the second slide rail 53, the sliding end of the second slide rail 53 is fixedly connected to the second slide rail 53, the sliding end of the second slide rail 53 is fixedly connected to a U-shaped positioning plate 54, one side of the U-shaped positioning plate 54 is fixedly connected to a camera 55, and the other side of the U-shaped positioning plate 54 is fixedly connected to a third motor 56.

[0036] The U-shaped positioning plate 54 is equipped with a fourth motor 57. The output end of the third motor 56 passes through the U-shaped positioning plate 54 and is fixedly connected to the fourth motor 57. The output end of the fourth motor 57 is fixedly connected to a first cylinder 58. The output end of the first cylinder 58 is fixedly connected to a dual-axis clamping cylinder 59. Both output ends of the dual-axis clamping cylinder 59 are fixedly connected to arc-shaped clamping plates, and the arc-shaped clamping plates are provided with arc-shaped grooves inside.

[0037] For details, please refer to Figure 6 , point a is the part that the arc groove of the double-axis clamping cylinder 59 needs to clamp when the steel bar is bent into an acute angle. Since it interferes with the fixed block 47, it is erected and cut. Point b is the part that the arc groove of the double-axis clamping cylinder 59 needs to clamp when the steel bar is bent into a right angle. Since it will not interfere with the fixed block 47, it will fall down and cut. Point c is the part that the arc groove of the double-axis clamping cylinder 59 needs to clamp when the steel bar is bent into an obtuse angle. Since it will not interfere with the fixed block 47, it will fall down and cut. 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 clamp reaches above one end of the steel bar with each different bending angle.

[0038] The extension of the output end of the first cylinder 58 is used to control the arc clamp to approach one end of the steel bar with different bending angles. The extension and retraction of the two output ends of the double-axis clamping cylinder 59 are used to control the arc clamp to clamp or put down 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 clamp so that the arc groove can remain parallel to one end of the fallen 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 clamp so that the arc groove can remain parallel to one end of the upright bent steel bar, and then position and clamp it.

[0039] The camera 55 contains a database and a judgment module. The database contains identification photos of steel bars at different bending angles.

[0040] Specifically, the camera 55 is used to take pictures of the bent steel bars and compare them with the identification photos of steel bars with different bending angles in the database. The judgment module then identifies the bending angle of the steel bars and divides 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 based on the obtained photos of the bent steel bars.

[0041] Figure 5 This represents the initial working state of the third motor 56, the fourth motor 57, the first cylinder 58, and the dual-axis clamping cylinder 59.

[0042] When the judgment module determines that the bending angle of the steel bar is an acute angle, Figure 6 At position a shown, in order to prevent the sharp-angle steel bar from interfering with the fixed block 47, the external manipulator stands up the sharp-angle steel bar and places it between the first cutter 45 and the second cutter 46. The sliding end of the first slide rail 51 and the sliding end of the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamp reaches above one end of the sharp-angle steel bar, and the output end of the third motor 56 starts to rotate clockwise until the arc groove is parallel to one end of the sharp-angle steel bar. The output end of the third motor 56 stops rotating, and the output end of the first cylinder 58 extends so that one end of the sharp-angle steel bar is located between the two arc grooves. The two output ends of the double-axis clamping cylinder 59 contract, thereby controlling the arc clamp to clamp and position the erected sharp-angle steel bar. After the cutting mechanism 4 cuts the sharp-angle steel bar, the positioning clamping mechanism 5 returns to its position.

[0043] When the judgment module determines that the bending angle of the steel bar is a right angle, Figure 6 At the position b shown, the right-angle steel bar will not interfere with the fixed block 47. The external manipulator will fall down the right-angle steel bar and place it between the first cutter 45 and the second cutter 46. The sliding end of the first slide rail 51 and the sliding end of the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc splint reaches above one end of the sharp-angle steel bar. The output end of the fourth motor 57 rotates ninety degrees clockwise. At this time, the arc groove is parallel to one end of the right-angle steel bar. 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-axis clamping cylinder 59 contract, thereby controlling the arc splint to clamp and position the fallen right-angle steel bar. After the cutting mechanism 4 cuts the sharp-angle steel bar, the positioning clamping mechanism 5 returns to its position.

[0044] When the judgment module determines that the bending angle of the reinforcing bar is an obtuse angle, such as Figure 6At the position c shown, the obtuse-angled steel bar will not interfere with the fixed block 47. The external manipulator will fall down the obtuse-angled steel bar and place it between the first cutter 45 and the second cutter 46. The sliding end of the first slide rail 51 and the sliding end of the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamp 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. The output end of the fourth motor 57 stops rotating, and 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-axis clamping cylinder 59 contract, thereby controlling the arc clamp to clamp and position the fallen obtuse-angled steel bar. After the cutting mechanism 4 cuts the obtuse-angled steel bar, the positioning clamping mechanism 5 returns to its position.

[0045] The camera 55 detects and photographs the bending angle of the bent steel bar and determines the bending degree of the steel bar, thereby standing up or falling the bent steel bar, determining the correct placement method, and controlling the third motor 56 and the fourth motor 57 to control the two arc clamps to rotate to different angles, thereby accurately clamping the steel bars with different bending angles, so that the steel bars with different bending angles can be automatically clamped and positioned when being cut, effectively preventing the bent steel bars from jumping when being cut.

[0046] In the second embodiment, when cutting multiple steel bars, the steel bars will collapse because the steel bars are put in and there are feed holes on the side. 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 feed stroke of the cutter, 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.

[0047] See also Figure 7-10 The arrangement mechanism 6 includes a fixed plate 61 fixedly connected to the upper side of the workbench 2, and a second cylinder 62 and a third cylinder 63 are respectively provided on both sides of the fixed plate 61. The second cylinder 62 and the third cylinder 63 are both fixedly connected to the workbench 2, and the output end of the second cylinder 62 is fixedly connected to the second clamping plate 65, and the output end of the third cylinder 63 is fixedly connected to the first clamping plate 64. A limiting plate 67 is provided on one side of the first clamping plate 64, and the limiting plate 67 is fixedly connected to the fixed plate 61, and a fifth motor 68 is fixedly connected to one side of the limiting plate 67.

[0048] Specifically, the external robotic arm places multiple steel bars above the fixed plate 61.

[0049] In this embodiment, three steel bars are used as an example. When three unstacked steel bars are placed, the output end of the second cylinder 62 extends to control the second clamping plate 65 to approach the first clamping plate 64, pushing the three steel bars placed on the fixing plate 61, thereby squeezing the three steel bars toward the first clamping plate 64 to converge.

[0050] 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 toward the middle of the fixing plate 61 , and finally positioning the three stacked steel bars above the flattening assembly 66 .

[0051] A first electromagnetic suction plate is provided on one side of the first clamping plate 64, and the output end of the fifth motor 68 passes through the limiting plate 67 and the first clamping plate 64 in sequence, and the output end of the fifth motor 68 is fixedly connected to the first electromagnetic suction plate. An electric slider 69 is provided inside the limiting plate 67, and the electric slider 69 is slidingly connected to the fixed plate 61. A second electromagnetic suction plate is provided on one side of the electric slider 69, and a tiling component 66 for tiling the stacked steel bars is provided inside the fixed plate 61.

[0052] Specifically, a motor and a roller are provided inside the electric slider 69. The motor controls the roller to rotate, so that the roller rolls inside the fixed plate 61, and then the electric slider 69 slides along the inside of the fixed plate 61. The second electromagnetic suction plate is used to absorb the flat surface of the steel bar, and the first electromagnetic suction plate is used to absorb the arc surface of the steel bar.

[0053] When the three steel bars are squeezed toward the first clamping plate 64 and converged, the output end of the second cylinder 62 retracts and drives the second clamping plate 65 to return to its position. The output end of the fifth motor 68 rotates to control the first electromagnetic suction plate to rotate ninety degrees clockwise, thereby making the first electromagnetic suction plate stick to the arc surface of the steel bar. The first electromagnetic suction plate is opened to absorb the three horizontally placed steel bars. The output end of the fifth motor 68 rotates to control the first electromagnetic suction plate to rotate ninety degrees counterclockwise, thereby returning the first electromagnetic suction plate to its position. At this time, the three horizontally placed steel bars are driven to rotate, and the three steel bars are now placed horizontally and vertically.

[0054] The output end of the second cylinder 62 extends to drive the second clamping plate 65 to move and limit the three horizontally and vertically placed steel bars, close the first electromagnetic suction plate and open the second electromagnetic suction plate, the electric slider 69 starts to move, and the second electromagnetic suction plate sucks one end of each steel bar in turn, thereby aligning one end of each steel bar and transporting the three horizontally and vertically placed steel bars, and then the three steel bars are arranged vertically for cutting. When cutting, the output end of the second cylinder 62 extends again to clamp the three steel bars. After the cutting is completed, the output end of the second cylinder 62 retracts again to limit the three steel bars.

[0055] The tiling assembly 66 includes a fourth cylinder 661 fixedly connected to the lower side of the workbench 2, and the first slider 662 is slidably connected to the inside of the fixed plate 61. The output end of the fourth cylinder 661 passes through the workbench 2, the fixed plate 61 and the first slider 662 in sequence, and the output end of the fourth cylinder 661 is fixedly connected to the second slider 663. The inside of the first slider 662 is respectively rotatably connected to the third rotating shaft 664 and the fourth rotating shaft 665. The outer sides of the third rotating shaft 664 and the fourth rotating shaft 665 are respectively fixedly connected to the first opening plate 666 and the second opening plate 667. The lower ends of the first opening plate 666 and the second opening plate 667 are both inclined surfaces.

[0056] 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 hits the lower end inclined surface 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 to move upward by the second slider 663, and the first slider 662 is also driven by the first opening plate 666 and the second opening plate 667 to move upward indirectly. While the first opening plate 666 and the second opening plate 667 move upward, they push the two steel bars that are close together to both sides.

[0057] At this time, the distance pushed away is not enough to allow one of the two steel bars above to fall down, so the output end of the fourth cylinder 661 continues to extend until the lowest point of the first open plate 666 and the second open plate 667 exceeds the top surface of the fixed plate 61. At this time, the lower end bevels of the first open plate 666 and the second open plate 667 are squeezed by the second slider 663, and the first open plate 666 and the second open plate 667 are driven by the second slider 663 to rotate counterclockwise and clockwise respectively, thereby opening the first open plate 666 and the second open plate 667, and then pushing the two steel bars farther respectively. At this time, the distance pushed away is enough to allow one of the two steel bars above to fall down, and the upper steel bar falls between the first open plate 666 and the second plate 667, and the first open plate 666 and the second plate 667 support the lower semicircular arc of the upper steel bar.

[0058] The retraction of the output end of the fourth cylinder 661 causes the second slider 663 to slide downwards. At this time, the first slider 662 is indirectly driven downwards by the second slider 663. The first opening plate 666 and the second opening plate 667 are also indirectly driven downwards by the first slider 662. One side of the first opening plate 666 and the second opening plate 667 is pressed by the fixed plate 61. The first opening plate 666 and the second opening plate 667 rotate clockwise and counterclockwise respectively, thereby closing the first opening plate 666 and the second opening plate 667 and squeezing out the upper steel bars until the output end of the fourth cylinder 661 is completely retracted and the first opening plate 666 and the second opening plate 667 are completely returned to their original positions. At this time, the three steel bars are no longer stacked, but are placed horizontally. The subsequent arrangement of the three steel bars has been specifically described in the above technical solution and will not be explained in detail here.

[0059] Before cutting, the three horizontally placed steel bars are arranged so that they are arranged into a horizontal vertical arrangement, and the three horizontally placed vertical steel bars are limited in conveyance, which effectively prevents the steel bars from falling before cutting and squeezing the steel bars in the same row during cutting, causing damage to the steel bars. When the three steel bars are stacked, the flattening component 66 can automatically flatten the three stacked steel bars into a horizontal horizontal arrangement, effectively preventing the three stacked steel bars from being unable to be attracted by the first electromagnetic suction plate and turned over.

[0060] In the third embodiment, when scrap is cut from steel bars that exceed the specified diameter and strength, the cut materials will be bounced due to the overload of the machine, causing the waste to fly everywhere, which is not conducive to the collection of the waste. It will also fly into the interior of the equipment and cause damage to the equipment. When people are near the equipment, the cut materials may be bounced onto the people and cause injuries, which poses a great safety hazard. Therefore, the following structure is designed to solve the above technical problems.

[0061] See also Figure 3 and Figure 4 The collection component 44 includes a collection box 441 fixedly connected inside the fixed frame 1. A second motor 442 is fixedly connected to one side of the collection box 441. The collection box 441 has a collection cavity inside. A top plate 444 is slidably connected inside the collection cavity. A U-shaped baffle 443 is slidably connected inside the collection box 441.

[0062] Specifically, the inside of the collection box 441 is used to store the cut waste material, and 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, thereby driving the U-shaped baffle 443 and the top plate 444 to move respectively.

[0063] Two second rotating shafts 446 are rotatably connected inside the collection box 441, one end of each second rotating shaft 446 is fixedly connected to the second gear 445, and the other end of each second rotating shaft 446 is fixedly connected to the third gear 447. One side of the U-shaped baffle 443 is fixedly connected to a plurality of gear columns 449, which are meshed with the second rotating shaft 446. The lower side of each second gear 445 is meshed with a sliding gear plate 448, which is fixedly connected to the top plate 444, and the sliding gear plate 448 is slidably connected to the collection box 441. The second motor 442 passes through the side wall of the collection box 441 and is fixedly connected to one of the third gears 447.

[0064] Specifically, in the initial state, the top plate 444 is located in the middle of the collection chamber.

[0065] When the steel bars exceeding the specified diameter and strength are cut to waste, 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 sticks to the inner wall of the collection chamber. The output end of the second motor 442 stops rotating. At this time, the U-shaped baffle 443 rises to the highest point. At this time, the cut material bounces off and is bounced to one side of the U-shaped baffle 443 and falls into the right side of the collection chamber.

[0066] When all the steel bars exceeding the specified diameter and strength are cut off, in order to prevent the U-shaped baffle 443 from interfering with the cutting and segmentation of the subsequent long steel bars, the output end of the second motor 442 begins 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 off-cuts on the right side of the collecting chamber to be transferred to the left side of the collecting chamber, thereby indirectly stacking all the off-cuts to prevent too much flying material from accumulating on the right side of the collecting chamber.

[0067] When cutting steel bars that exceed the specified diameter and strength, the second gear 445 and the third gear 447 are controlled to rotate by the output end of the second motor 442, thereby driving the U-shaped baffle 443 and the top plate 444 to move respectively, thereby effectively blocking the flying steel bar cuttings and dropping them into the interior of the collection box 441, and while the top plate 444 returns to its position, it indirectly drives the cuttings on the right side of the collection chamber to be transferred to the left side of the collection chamber, thereby indirectly stacking all the cuttings together to prevent excessive flying materials from accumulating on the right side of the collection chamber and causing flying materials to overflow.

[0068] Example 4, a method for cutting steel bars to prevent jumping, using the above-mentioned steel bar cutting device to prevent jumping, comprising the following steps: S1: When multiple steel bars need to be cut, the arranging mechanism 6 arranges the multiple straight steel bars into a vertical and horizontal state, and limits and transports them.

[0069] More specifically, S11: When three unstacked steel bars are placed, the output end of the second cylinder 62 extends to control the second clamping plate 65 to approach the first clamping plate 64, pushing the three steel bars placed on the fixing plate 61, thereby squeezing the three steel bars toward the first clamping plate 64 to converge.

[0070] S12: When the three steel bars are squeezed toward the first clamping plate 64 and converge, the output end of the second cylinder 62 retracts and drives the second clamping plate 65 to return to its original position. The output end of the fifth motor 68 rotates to control the first electromagnetic suction plate to rotate ninety degrees clockwise, thereby making the first electromagnetic suction plate stick to the arc surface of the steel bar. The first electromagnetic suction plate is opened to attract the three horizontally placed steel bars. The output end of the fifth motor 68 rotates to control the first electromagnetic suction plate to rotate ninety degrees counterclockwise, thereby returning the first electromagnetic suction plate to its original position. At this time, the three horizontally placed steel bars are driven to rotate, and the three steel bars are now placed horizontally and vertically.

[0071] S13: When three stacked steel bars are placed, the output ends of the second cylinder 62 and the third cylinder 63 extend simultaneously, thereby pushing the stacked steel bars toward the middle of the fixed plate 61, and finally placing the three stacked steel bars above the tiling assembly 66.

[0072] S14: The output end of the second cylinder 62 extends to drive the second clamping plate 65 to move and limit the three horizontally and vertically placed steel bars, close the first electromagnetic suction plate and open the second electromagnetic suction plate, the electric slider 69 starts to move, the second electromagnetic suction plate sucks one end of each steel bar in turn, thereby aligning one end of each steel bar, and transporting the three horizontally and vertically placed steel bars, and then vertically arranging the three steel bars for cutting. When cutting, the output end of the second cylinder 62 extends again to clamp the three steel bars. After the cutting is completed, the output end of the second cylinder 62 retracts again to limit the three steel bars.

[0073] 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 hits the lower end inclined surface 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 to move upward by the second slider 663. The first slider 662 is also driven by the first opening plate 666 and the second opening plate 667 to move upward indirectly. While the first opening plate 666 and the second opening plate 667 move upward, they push the two steel bars that are close together to both sides.

[0074] S16: At this time, the distance pushed away is not enough to allow one of the two steel bars above to fall down, so the output end of the fourth cylinder 661 continues to extend until the lowest point of the first open plate 666 and the second open plate 667 exceeds the top surface of the fixed plate 61. At this time, the lower end bevels of the first open plate 666 and the second open plate 667 are squeezed by the second slider 663, and the first open plate 666 and the second open plate 667 are driven by the second slider 663 to rotate counterclockwise and clockwise respectively, thereby opening the first open plate 666 and the second open plate 667, and then pushing the two steel bars farther respectively. At this time, the distance pushed away is enough to allow one of the two steel bars above to fall down, and the upper steel bar falls between the first open plate 666 and the second open plate 667, and the first open plate 666 and the second open plate 667 support the lower semicircular arc of the upper steel bar.

[0075] S17: The output end of the fourth cylinder 661 retracts and drives the second slider 663 to slide downward. At this time, the first slider 662 is indirectly driven to move downward by the second slider 663, and the first opening plate 666 and the second opening plate 667 are also indirectly driven to move downward by the first slider 662. One side of the first opening plate 666 and the second opening plate 667 is squeezed by the fixed plate 61, and the first opening plate 666 and the second opening plate 667 rotate clockwise and counterclockwise respectively, thereby closing the first opening plate 666 and the second opening plate 667 and squeezing out the upper steel bars until the output end of the fourth cylinder 661 is fully retracted, and the first opening plate 666 and the second opening plate 667 are fully returned to their positions. At this time, the three steel bars are no longer in a stacked state, but are placed horizontally. The above technical solution has been specifically described in detail for the subsequent arrangement of the three steel bars, and no further explanation will be given here.

[0076] S2: When it is necessary to cut the bent steel bar, the camera 55 captures the bending angle of the bent steel bar and judges the degree of bending of the steel bar, thereby controlling the third motor 56 and the fourth motor 57 to control the two arc clamps to rotate at different angles, so as to accurately clamp the steel bars with different bending angles.

[0077] The more specific steps of S2 are as follows: S21: Camera 55 takes an image of the bent steel bar and compares it with the identification photos of steel bars with different bending angles in the internal database. Then, it identifies the bending angle of the steel bar and classifies the bending angle of the steel bar into three types of bent steel bars: acute angle steel bars, right angle steel bars, and obtuse angle steel bars based on the obtained photos of the bent steel bars.

[0078] S22: When the judgment module determines that the bending angle of the steel bar is an acute angle, in order to prevent the acute-angle steel bar from interfering with the fixed block 47, the external manipulator stands up the acute-angle steel bar and places it between the first cutter 45 and the second cutter 46. The sliding end of the first slide rail 51 and the sliding end of the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamp reaches above one end of the acute-angle steel bar, and the output end of the third motor 56 starts to rotate clockwise until the arc groove is parallel to one end of the acute-angle steel bar. The output end of the third motor 56 stops rotating, and the output end of the first cylinder 58 extends so that one end of the acute-angle steel bar is located between the two arc grooves. The two output ends of the double-axis clamping cylinder 59 contract, thereby controlling the arc clamp to clamp and position the erected acute-angle steel bar. After the cutting mechanism 4 cuts the acute-angle steel bar, the positioning clamping mechanism 5 returns to its position.

[0079] S23: When the judgment module determines that the bending angle of the steel bar is a right angle, the right-angle steel bar will not interfere with the fixed block 47. The external manipulator will fall down the right-angle steel bar and place it between the first cutter 45 and the second cutter 46. The sliding end of the first slide rail 51 and the sliding end of the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamp reaches above one end of the sharp-angle steel bar. The output end of the fourth motor 57 rotates ninety degrees clockwise. At this time, the arc groove is parallel to one end of the right-angle steel bar. 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-axis clamping cylinder 59 contract, thereby controlling the arc clamp to clamp and position the fallen right-angle steel bar. After the cutting mechanism 4 cuts the sharp-angle steel bar, the positioning clamping mechanism 5 returns to its position.

[0080] S24: When the judgment module determines that the bending angle of the steel bar is an obtuse angle, the obtuse-angle steel bar will not interfere with the fixed block 47. The external manipulator will fall down the obtuse-angle steel bar and place it between the first cutter 45 and the second cutter 46. The sliding end of the first slide rail 51 and the sliding end of the second slide rail 53 move to control the U-shaped positioning plate 54 to move, so that the arc clamp 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, and 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-axis clamping cylinder 59 contract, thereby controlling the arc clamp to clamp and position the fallen obtuse-angle steel bar. After the cutting mechanism 4 cuts the obtuse-angle steel bar, the positioning clamping mechanism 5 returns to its position.

[0081] S3: When the transmission mechanism 3 controls the first cutter 45 to move and approach the second cutter 46, the steel bar between the first cutter 45 and the second cutter 46 is cut off.

[0082] S4: When cutting, the collection component 44 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 flying material. When cutting and dividing individual small-diameter steel bars, it switches to the normal cutting and dividing mode and no longer blocks the material. It also indirectly pushes the flying material blocked by the previous material blocking mode.

[0083] The more specific steps of S4 are as follows: S41: When cutting waste material from steel bars exceeding the specified diameter and strength, 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 is attached to the inner wall of the collection chamber. The output end of the second motor 442 stops rotating. At this time, the U-shaped baffle 443 rises to the highest point. At this time, the cut material is bounced and thrown to one side of the U-shaped baffle 443 and falls into the right side of the collection chamber.

[0084] S42: After all the steel bars exceeding the specified diameter and strength have been cut off, in order to prevent the U-shaped baffle 443 from interfering with the subsequent cutting 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 chamber to be transferred to the left side of the collection chamber, thereby indirectly concentrating all the cut material and preventing too much flying material from accumulating on the right side of the collection chamber.

The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
