Description

Technical Field

[0001] This invention relates to the field of steel plate shearing technology, and more specifically, to a high-precision equidistant cutting device and process for steel processing. Background Technology

[0002] Steel plate shearing equipment is an important piece of equipment in the field of metal processing.

[0003] Chinese Patent Publication No. CN113492230A discloses a steel plate shearing method and device for improving efficiency. The steel plate shearing method includes the following steps: a large plate is conveyed to a slitting shearing device via a first conveying device, and the slitting shearing device performs longitudinal shearing on the large plate along the longitudinal shearing line to obtain an incompletely sheared large plate with the rear end still connected and the other parts longitudinally cut apart; the incompletely sheared large plate is conveyed sequentially from the front end to the rear end via a second conveying device to a fixed-length shearing device, and the fixed-length shearing device performs one or more transverse shearings on the cut part of the incompletely sheared large plate along the transverse shearing line, and each shearing along the transverse shearing line yields at least two small plates.

[0004] The above technical solution improves the shearing efficiency of steel plates. However, in the traditional shearing equipment, the steel plate is first placed on the surface of the cutting table and fixed, and then the shearing blade descends to shear the steel plate. However, the above shearing equipment cannot perform shearing during the steel plate conveying process, which affects the shearing efficiency of the shearing equipment. Moreover, during the shearing process, the cutting force exerted by the descending cutting blade on the steel plate will cause the cutting surfaces on both sides of the cutting line to undergo slight deformation in the direction of the cutting force. This is not conducive to the subsequent steel plate production and processing, and thus affects the cutting quality of the steel plate by the shearing equipment. Summary of the Invention

[0009] Preferably, a support frame 1 is fixedly installed on one end surface of the cutting blade, and a roller 1 for pushing the extrusion frame 1 is rotatably connected to the bottom of the support frame 1. Two support frames 2 are fixedly installed on the other end surface of the cutting blade, and rollers 2 for pushing the extrusion frame 2 are rotatably connected to the bottom of both support frames 2.

[0010] Preferably, one end of the first spring is fixedly connected to the surface of the guide rod, the other end of the first spring is fixedly connected to the L-shaped plate, one end of the second spring is fixedly connected to the bottom surface of the contact plate, and the other end of the second spring is fixedly connected to the surface of the connecting plate.

[0011] Preferably, each corresponding surface of the cutting device has a through-type lower groove, and a matching lower moving plate is slidably connected inside each of the two lower moving plates. A connecting horizontal plate is fixedly installed on the inner side of each of the two lower moving plates. The two end surfaces of the cutting table are respectively fixedly connected to the two connecting horizontal plates. Each corresponding surface of the cutting device has a through-type upper groove, and a frame plate is slidably connected inside each of the two upper grooves. Multiple telescopic devices are fixedly installed on the bottom surface of the frame plate, and the telescopic ends of the telescopic devices are fixedly connected to the cutting blade. A vertical plate is fixedly installed between the lower moving plates and the frame plate. A mounting base is fixedly installed on the surface of the cutting equipment. A second telescopic device is fixedly installed on the surface of the mounting base. A vertical plate is fixedly installed on the telescopic end of the second telescopic device.

A matching position sensor is slidably connected inside each of the two mounting brackets. A controller is fixedly installed on the surface of the cutting equipment.

[0012] Preferably, an auxiliary frame is fixedly installed on the surface of the cutting equipment, a crossbeam is fixedly installed on one side surface of the cutting table, a support plate is fixedly installed on the middle surface of the crossbeam, a movable groove is opened on the surface of the crossbeam, and two clamping frames are slidably connected inside the movable groove, and multiple rotating wheels are rotatably connected to the inner sides of the two clamping frames.

[0013] Preferably, a bidirectional lead screw is rotatably connected inside the movable groove, the bidirectional lead screw is threadedly connected to the two clamping frames, a motor is fixedly mounted on one end surface of the cross frame, and the output end of the motor is fixedly connected to the bidirectional lead screw.

[0014] A high-precision equidistant cutting process for steel processing includes the following steps: S1: First, the steel plate is pushed onto the surface of the cutting table through the auxiliary frame. Then, the steel plate is placed on the surface of the support plate through the cutting table. As the steel plate continues to be pushed, when the end of the steel plate moves to the position corresponding to the position sensor, the vertical plate moves, which in turn moves the vertical plate. This causes the lower moving plate and the support plate to move simultaneously with the vertical plate. The movement of the two lower moving plates moves the cutting table, and the movement of the support plate moves the cutting blade. This causes the cutting blade, the cutting table, and the steel plate to move synchronously. S2: The cutting blade moves downward, causing support frame one and support frame two to move downward, so that the rotating column rotates the U-shaped frame ninety degrees and becomes parallel to the slot seat. At this time, roller one moves from the inclined rail of extrusion frame one to the vertical rail. After the U-shaped frame rotates ninety degrees, multiple U-shaped frames are connected end to end and arranged in sequence to form a complete cutting slot. At this time, multiple contact plates follow the movement of the U-shaped frame and become parallel to the slot seat. S3: The skateboard moves along with multiple wedge blocks, which simultaneously squeeze the guide rod. The guide rod slides towards the U-shaped frame, causing the extrusion seat to squeeze the lifting seat. The lifting seat moves upward, causing the contact plates to press against both sides of the cutting line on the bottom surface of the steel plate. Multiple contact plates move towards each other simultaneously, and are arranged in a row, end to end, to press against both sides of the cutting line on the bottom surface of the steel plate. At this time, roller two moves from the inclined rail of extrusion frame two to the vertical rail. As telescopic device one continues to move, the cutting blade moves downward to cut the steel plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) When this high-precision equidistant cutting device for steel processing is in use, as the cutting blade moves downward, the sliding tooth plate moves into the groove and drives multiple gears to rotate, so that the U-shaped frame rotates 90 degrees and is parallel to the groove seat. After the U-shaped frame rotates 90 degrees, multiple U-shaped frames are connected end to end and arranged in sequence to form a complete cutting groove. At this time, multiple abutment plates follow the movement of the U-shaped frame and are parallel to the groove seat. As the telescopic device continues to extend, the extrusion frame 2 moves and drives two sliding plates into the groove. The sliding plates move and drive multiple wedge blocks to move. The wedge blocks move and simultaneously extrude the guide rod. The guide rod slides towards the U-shaped frame and drives the extrusion seat to move and extrude the lifting seat. Multiple abutment plates move towards each other at the same time. Multiple abutment plates are connected end to end and arranged in sequence to abut against both sides of the cutting line on the bottom surface of the steel plate. Compared with traditional partial shearing equipment, this cutting device abuts against both sides of the cutting line on the bottom surface of the steel plate before cutting the steel plate. During the steel plate cutting process, the cross section at the cutting line position of the steel plate is prevented from being deformed by the cutting force, thus ensuring the shearing quality of the steel plate by the cutting equipment.

[0016] (2) When the end of the steel plate moves to the position corresponding to the position sensor, the vertical plate moves with the vertical plate, so that the lower moving plate and the frame plate move with the vertical plate at the same time, and thus the cutting blade and the cutting table move synchronously. The cutting blade moves downward to cut the steel plate. When the steel plate is cut, the cutting table is reset at the same time during the cutting blade reset process. At this time, the steel plate continues to advance, saving the time of cutting the steel plate again, and thus improving the cutting efficiency of the cutting equipment for the steel plate.

[0017] (3) When using this high-precision equidistant cutting device for steel processing, the distance between the two clamping frames is adjusted according to the width of the steel plate to be cut. First, the motor is started to rotate. The rotation of the motor drives the bidirectional lead screw to rotate, which in turn causes the two clamping frames to move towards each other. The movement of the two clamping frames towards each other causes multiple rotating wheels to move towards each other, which in turn makes the distance between the two rotating wheels adapt to the width of the steel plate to be cut. At this time, during the conveying process of the steel plate, the two sides of the steel plate enter the space between the rotating wheels. The movement of the steel plate causes the rotating wheels to rotate. The two rotating wheels limit the steel plate, which not only prevents the steel plate from shifting position during the rotation of the U-shaped frame, but also prevents the cutting blade from curling up during the cutting process of the steel plate, further ensuring the cutting quality of the steel plate by the cutting equipment.

[0020] Example 1: Please refer to Figure 1 - Figure 13A high-precision equidistant cutting device for steel processing includes a cutting device 1 and a cutting table 2 disposed on its inner surface. The cutting table 2 is used for shearing and supporting a steel plate 39, and the steel plate 39 to be cut is placed on the surface of the cutting table 2. The steel plate 39 is a conventional steel plate 39 in the prior art. A groove seat 3 is opened on the surface of the cutting table 2. Multiple fixed seats 4 are fixedly installed on the inner bottom surface of the groove seat 3. A matching rotating column 5 is rotatably connected inside any fixed seat 4. A U-shaped frame 6 is fixedly installed on the top surface of any rotating column 5. After the U-shaped frame 6 is rotated 90 degrees, the multiple U-shaped frames 6 are connected end to end and arranged in sequence to form a complete cutting groove. L-shaped plates 7 are fixedly installed on both sides of the U-shaped frame 6. The surfaces of the two L-shaped plates 7 are A through-type guide rod 8 is slidably connected, serving as the movement guide for the extrusion seat 10. Each guide rod 8 has a spring 9 fitted onto its surface for resetting. One end of the guide rod 8 extends to the inner side of the U-shaped frame 6, and the extrusion seat 10 is fixedly mounted on the surface of one end of the guide rod 8. Connecting plates 11 are fixedly mounted on the inner walls of both sides of the U-shaped frame 6. Each connecting plate 11 has a through-type slot 12 on its surface. A matching lifting seat 13 is slidably connected inside the slot 12, with the bottom of the lifting seat 13 contacting the extrusion seat 10. The top surface of the lifting seat 13 is fixedly mounted with abutment plates 14 supporting the two sides of the bottom cutting line of the steel plate 39. The guide rod 8 slides towards the U-shaped frame 6, causing the extrusion seat 10 to move and extrude the lifting seat 13. Multiple... The contact plates 14 move towards each other simultaneously, with multiple contact plates 14 arranged end to end in sequence, abutting both sides of the cutting line on the bottom surface of the steel plate 39. A spring 15 elastically connects the contact plates 14 to the connecting plate 11. A cutting blade 17 for cutting the steel plate 39 is positioned above the cutting table 2. The cutting blade 17 is a conventional CNC cutting blade 17. As the cutting blade 17 moves downwards, the sliding tooth plate 19 moves into the slot 18, causing multiple gears 22 to rotate, resulting in the U-shaped frame 6 rotating 90 degrees parallel to the slot seat 3. After the U-shaped frame 6 rotates 90 degrees, multiple U-shaped frames 6 are arranged end to end in sequence, forming a complete cutting slot. At this time, multiple contact plates 14 follow the movement of the U-shaped frame 6 and move parallel to the slot seat 3. With the extension device... 38 continues to extend, and the extrusion frame 27 moves with the two slide plates 24 into the groove 23. The slide plates 24 move with the multiple wedge blocks 25. The wedge blocks 25 move simultaneously and extrude the guide rod 8. The guide rod 8 slides towards the U-shaped frame 6 and moves with the extrusion seat 10 to extrude the lifting seat 13. Multiple contact plates 14 move towards each other at the same time. The multiple contact plates 14 are arranged in sequence, end to end, to hold the two sides of the bottom cutting line of the steel plate 39. Compared with traditional partial shearing equipment, this cutting equipment 1 holds the two sides of the bottom cutting line of the steel plate 39 before cutting the steel plate 39. During the cutting process of the steel plate 39, the cross section at the cutting line position of the steel plate 39 is prevented from being deformed by the cutting force, thus ensuring the shearing quality of the steel plate 39 by the cutting equipment 1.When the end of the steel plate 39 moves to the position corresponding to the position sensor 45, the vertical plate 43 moves, causing the vertical plate 40 to move as well. This causes the lower moving plate 34 and the support plate 37 to move simultaneously with the vertical plate 40, thereby synchronizing the movement of the cutting blade 17 and the cutting table 2. The cutting blade 17 moves downward to shear the steel plate 39. After the steel plate 39 has been sheared, during the resetting process of the cutting blade 17, the cutting table 2 simultaneously resets, allowing the steel plate 39 to continue advancing. This saves time for the steel plate 39 to be sheared again, thus improving the shearing efficiency of the cutting equipment 1 on the steel plate 39.

[0021] A slot 18 is provided on one side of the inner wall of the slot 3. A matching sliding tooth plate 19 is slidably connected inside the slot 18. An extrusion frame 20 is fixedly installed on one end surface of the sliding tooth plate 19. A spring 21 is elastically connected between the other end surface of the sliding tooth plate 19 and the slot 18. The spring 21 is used for the sliding tooth plate 19 to move and reset. A gear 22 that meshes with the sliding tooth plate 19 is fixedly installed on the surface of any rotating column 5. Multiple balls 16 are provided on the surface of the U-shaped frame 6. The arrangement of the balls 16 not only ensures the smooth conveying of the steel plate 39, but also reduces the friction with the bottom surface of the steel plate 39, making the rotation of the U-shaped frame 6 smoother.

[0022] The extrusion frame 20 includes a slanted rail and a vertical rail. One end of the spring 21 is fixedly connected to the sliding tooth plate 19, and the other end of the spring 21 is fixedly connected to the inner wall of the slot 18. The inner walls on both sides of the slot seat 3 are provided with sliding grooves 23. The sliding groove 23 is slidably connected to a matching slide plate 24. Multiple wedge blocks 25 for extruding guide rods 8 are fixedly installed on the inner side of the slide plate 24. A spring 26 is elastically connected between the slide plate 24 and the sliding groove 23. The spring 26 is used for the slide plate 24 to return to its original position. One end of the spring 26 is fixedly connected to the slide plate 24, and the other end of the spring 26 is fixedly connected to the inner wall of the sliding groove 23.

[0023] The other end of the slide plate 24 is fixedly installed with an extrusion frame 27, which includes a slanted rail and a vertical rail. The height of the extrusion frame 27 is lower than the height of the extrusion frame 20. The surface of the cutting table 2 is provided with several ball bearings 28. The ball bearings 28 reduce the friction during the conveying process of the steel plate 39.

[0024] A support frame 29 is fixedly mounted on one end surface of the cutting blade 17. A roller 30 for pushing the extrusion frame 20 is rotatably connected to the bottom of the support frame 29. Two support frames 31 are fixedly mounted on the other end surface of the cutting blade 17. A roller 32 for pushing the extrusion frame 27 is rotatably connected to the bottom of each support frame 31. The arrangement of rollers 30 and 32 reduces the friction on the extrusion frame 20 and the extrusion frame 27.

[0025] One end of spring 9 is fixedly connected to the surface of guide rod 8, and the other end of spring 9 is fixedly connected to L-shaped plate 7. One end of spring 15 is fixedly connected to the bottom surface of contact plate 14, and the other end of spring 15 is fixedly connected to the surface of connecting plate 11.

[0026] The corresponding surfaces of the cutting device 1 are provided with through-type lower grooves 33. A matching lower moving plate 34 is slidably connected inside each of the two lower moving plates 34. A connecting horizontal plate 35 is fixedly installed on the inner side of each of the two lower moving plates 34. The two end surfaces of the cutting table 2 are respectively fixedly connected to the two connecting horizontal plates 35. The corresponding surfaces of the cutting device 1 are provided with through-type upper grooves 36. A frame plate 37 is slidably connected inside each of the two upper grooves 36. Multiple telescopic actuators 38 are fixedly installed on the bottom surface of the frame plate 37. The telescopic actuators 38 are conventional electrically controlled push rods in the prior art. The telescopic ends of the telescopic actuators 38 are fixedly connected to the cutting blade 17. A vertical plate 40 is fixedly installed between the lower moving plate 34 and the frame plate 37. A mounting base 41 is fixedly installed on the surface of the cutting device 1. A second telescopic actuator 42 is fixedly installed on the surface of the mounting base 41. The second telescopic actuator 42 is a conventional telescopic actuator in the prior art. The electric push rod of the telescopic device 1 has a vertical plate 43 fixedly installed at the telescopic end of the telescopic device 2 42. The inner side of the vertical plate 43 is fixedly connected to the surface of the vertical plate 40. Mounting brackets 44 are fixedly installed on both inner walls of the cutting device 1. The two mounting brackets 44 are slidably connected to the corresponding position sensors 45. The position sensors 45 are conventional position sensors in the prior art. A controller 46 is fixedly installed on the surface of the cutting device 1. The controller 46 is a conventional programmable control device in the prior art. The controller 46 is electrically connected to the telescopic device 1 38 through wires, the controller 46 is electrically connected to the telescopic device 2 42 through wires, and the controller 46 is electrically connected to the position sensors 45 through wires. The controller 46 receives and processes the signals sent by the position sensors 45 and controls the operation of the telescopic device 2 42 and the telescopic device 1 38. This is the prior art and will not be described in detail here.

[0027] The steps of using this invention are as follows: When using this high-precision equidistant cutting device for steel processing, the position sensor 45 is adjusted to slide inside the mounting frame 44 according to the required cutting length of the steel plate 39, so that the distance between the position sensor 45 and the centerline of the cutting table 2 is equal to the required cutting length of the steel plate 39. In the initial position, the orientation of the U-shaped frame 6 is perpendicular to the slot seat 3. First, the steel plate 39 is pushed onto the surface of the cutting table 2 through the auxiliary frame 47. Then, the steel plate 39 is placed on the surface of the support plate 49 through the cutting table 2. As the steel plate 39 continues to be pushed, when the end of the steel plate 39 moves to the position corresponding to the position sensor 45, the detection signal of the position sensor 45 is transmitted to the controller 46. The controller 46 controls the expansion joint 42 to retract. The movement of plate 42 causes the vertical plate 43 to move, which in turn causes the vertical plate 40 to move, resulting in the lower moving plate 34 and the support plate 37 moving simultaneously with the vertical plate 40. The movement of the two lower moving plates 34 causes the cutting table 2 to move, and the movement of the support plate 37 causes the cutting blade 17 to move, thereby causing the cutting blade 17, the cutting table 2, and the steel plate 39 to move synchronously. At this time, the telescopic device 1 38 extends and moves the cutting blade 17 downward. The downward movement of the cutting blade 17 causes the support frame 1 29 and the support frame 2 31 to move downward. The support frame 1 29 and the support frame 2 31 respectively move the roller 1 30 and the roller 2 32 downward. Since the height of the extrusion frame 2 27 is lower than the height of the extrusion frame 1 20, during the downward movement of the cutting blade 17, the roller 1 30 first... When the extrusion frame 20 contacts the inclined rail, the movement of the extrusion frame 20 causes the sliding tooth plate 19 to move into the slot 18, compressing the spring 21. The movement of the sliding tooth plate 19 causes multiple gears 22 to rotate, which in turn causes the rotating column 5 to rotate the U-shaped frame 6 ninety degrees to be parallel to the slot seat 3. At this time, the roller 30 moves from the inclined rail of the extrusion frame 20 to the vertical rail. After the U-shaped frame 6 rotates ninety degrees, multiple U-shaped frames 6 are arranged end to end to form a complete cutting groove. At this time, multiple contact plates 14 follow the movement of the U-shaped frame 6 to be parallel to the slot seat 3. As the telescopic device 38 continues to extend, at the moment when the roller 30 moves to the vertical rail, the roller 32 contacts the inclined rail of the extrusion frame 27. The roller 30 moves on the vertical rail, and the sliding tooth plate 19 does not move. When the position changes, the extrusion frame 27 moves, causing the two slide plates 24 to move into the groove 23 and extrude the spring 4 26. The slide plates 24 move, causing multiple wedge blocks 25 to move. The wedge blocks 25 move and extrude the guide rod 8. The guide rod 8 slides towards the U-shaped frame 6, causing the extrusion seat 10 to move and extrude the lifting seat 13. The lifting seat 13 moves upward, causing the contact plate 14 to move and press against both sides of the bottom cutting line of the steel plate 39. Multiple contact plates 14 move towards each other at the same time. Multiple contact plates 14 are arranged in a row, end to end, to press against both sides of the bottom cutting line of the steel plate 39. At this time, the roller 2 32 moves from the inclined rail of the extrusion frame 27 to the vertical rail. As the telescopic device 1 38 continues to move, the cutting blade 17 moves downward to cut the steel plate 39.This scheme involves the sliding tooth plate 19 moving into the slot 18 during the downward movement of the cutting blade 17, causing multiple gears 22 to rotate. This rotates the U-shaped frame 6 90 degrees, making it parallel to the slot seat 3. After the U-shaped frame 6 rotates 90 degrees, multiple U-shaped frames 6 are arranged end to end, forming a complete cutting slot. At this time, multiple abutment plates 14 follow the movement of the U-shaped frame 6 and are parallel to the slot seat 3. As the telescopic device 1 38 continues to extend, the extrusion frame 27 moves, causing two sliding plates 24 to move into the slide groove 23. The sliding plates 24 move, causing multiple wedge blocks 25 to move. The wedge blocks 25 simultaneously extrude and extrude the guide rod 8. The guide rod 8 slides towards the U-shaped frame 6, causing the extrusion seat 10 to move and extrude the lifting seat 13. Multiple abutment plates 14 move towards each other simultaneously, arranged end to end, abutting both sides of the cutting line on the bottom surface of the steel plate 39. Compared with traditional partial shearing methods, this method achieves a more efficient and effective cutting solution. Before cutting the steel plate 39, the cutting equipment 1 abuts both sides of the cutting line on the bottom surface of the steel plate 39. During the cutting process, this prevents deformation of the cross-section at the cutting line position of the steel plate 39 due to the cutting force, ensuring the shearing quality of the steel plate 39 by the cutting equipment 1. When the end of the steel plate 39 moves to the position corresponding to the position sensor 45, the vertical plate 43 moves, causing the vertical plate 40 to move as well. This causes the lower moving plate 34 and the support plate 37 to move simultaneously with the vertical plate 40, thereby causing the cutting blade 17 and the cutting table 2 to move synchronously. The cutting blade 17 moves downward to shear the steel plate 39. After the steel plate 39 is sheared, during the resetting process of the cutting blade 17, the cutting table 2 also resets simultaneously. At this time, the steel plate 39 continues to advance, saving the time for the steel plate 39 to be sheared again, thus improving the shearing efficiency of the cutting equipment 1 on the steel plate 39.

[0028] Example 2: Please refer to Figure 4 - Figure 7The difference from Embodiment 1 is that an auxiliary frame 47 is fixedly installed on the surface of the cutting device 1, a crossbeam 48 is fixedly installed on one side of the cutting table 2, a support plate 49 is fixedly installed on the middle surface of the crossbeam 48, and a movable groove 50 is opened on the surface of the crossbeam 48. Two clamping frames 51 are slidably connected inside the movable groove 50. Multiple rotating wheels 52 are rotatably connected to the inner sides of the two clamping frames 51. The distance between the two clamping frames 51 is adjusted according to the width of the steel plate 39 to be cut. First, the motor 54 is started to rotate. The rotation of the motor 54 drives the bidirectional lead screw 53 to rotate, thereby making... The two clamping frames 51 move towards each other, which in turn causes multiple rotating wheels 52 to move towards each other. This makes the distance between the two rotating wheels 52 adapt to the width of the steel plate 39 to be sheared. At this time, during the conveying process of the steel plate 39, the two sides of the steel plate 39 enter the space between the rotating wheels 52. The movement of the steel plate 39 causes the rotating wheels 52 to rotate. The two rotating wheels 52 limit the position of the steel plate 39, which not only prevents the position of the steel plate 39 from shifting during the rotation of the U-shaped frame 6, but also prevents the cutting blade 17 from warping the edges of the steel plate 39 during the cutting process, further ensuring the shearing quality of the steel plate 39 by the cutting equipment 1.

[0029] The movable slot 50 is internally rotatably connected to a bidirectional lead screw 53, which is threadedly connected to two clamping frames 51. A motor 54 is fixedly mounted on one end of the cross frame 48, and the output end of the motor 54 is fixedly connected to the bidirectional lead screw 53. The motor 54 is a conventional forward and reverse reversing motor in the prior art.

[0030] The steps of using this invention are as follows: When using this high-precision equidistant cutting device for steel processing, to prevent the steel plate 39 from shifting position on the surface of the U-shaped frame 6 during rotation, and to prevent the steel plate 39 from warping during cutting by the cutting blade 17, the distance between the two clamping frames 51 is adjusted according to the width of the steel plate 39 before shearing. First, the motor 54 is started to rotate, which drives the bidirectional lead screw 53 to rotate, thereby causing the two clamping frames 51 to move towards each other. The opposing motion causes multiple rotating wheels 52 to move in opposite directions, thereby adapting the distance between the two rotating wheels 52 to the width of the steel plate 39 to be sheared. At this time, during the conveying process of the steel plate 39, the two sides of the steel plate 39 enter the space between the rotating wheels 52. The movement of the steel plate 39 causes the rotating wheels 52 to rotate. The two rotating wheels 52 limit the position of the steel plate 39, which not only prevents the position of the steel plate 39 from shifting during the rotation of the U-shaped frame 6, but also prevents the cutting blade 17 from warping the edges of the steel plate 39 during the cutting process, further ensuring the shearing quality of the steel plate 39 by the cutting equipment 1.
