Description

Technical Field

[0001] This invention relates to the field of shearing machine technology, specifically to a shearing machine for metal sheets with precisely adjustable processing angles. Background Technology

[0002] With the rapid development of the product manufacturing industry, the demand for processing metal sheets is constantly increasing, which in turn increases the requirements for the processing precision of shearing machines. During the shearing process of metal sheets, the angle of the blade directly affects the quality and shape of the cut edge. If the blade angle is inappropriate, the shearing force may not be evenly applied to the sheet, resulting in uneven cut edges, burrs, and other defects.

[0003] Different thicknesses and materials of metal sheets require different shearing forces during cutting, thus necessitating adjustments to the blade angle to accommodate these variations. Furthermore, traditional shearing machines, when processing angled metal sheets, do not maintain a parallel relationship between the blade and the sheet, making the sheet prone to deformation upon contact. Therefore, a shearing machine for metal sheets with precisely adjustable processing angles is extremely important.

[0004] When the blade angle is precisely adjusted, the shearing force can be applied more evenly to the material, resulting in cleaner, smoother cut edges. This is because a suitable blade angle ensures a more reasonable distribution of shearing force on the material, reducing unnecessary shearing deformation and stress concentration. At the same time, precise blade angle adjustment also helps reduce friction and wear between the blade and the material, extending the blade's lifespan.

[0005] Metal sheet shearing machines with precisely adjustable processing angles control the direction and distribution of shearing force by adjusting the blade angle, thus solving the problems of uneven cut edges and burrs caused by improper angles.

[0006] Patent document CN114505526B discloses a CNC shearing machine that facilitates the fixed transmission of sheet metal. The above patent enables the clamping of irregularly shaped sheets at different angles, but it cannot achieve the precise adjustment function of the shearing machine blade angle.

[0007] Patent document CN114131108B discloses a shearing machine with a quick cutting positioning device. The above patent enables clamping of plates of different widths and thicknesses and adjustment of the plate angle, but the above patent cannot realize the function of detecting the thickness of the metal plate.

[0008] Patent document CN113231683B discloses a metal sheet shearing machine that facilitates the adsorption of sheet metal. The above patent realizes the fixing of the cutting blade and the subsequent convenient replacement, solving the problem of inconvenient movement caused by the excessive weight of the metal sheet. However, the above patent cannot realize the function of adjusting the cutting position of the shearing machine.

[0009] Patent document CN104174920B discloses a fully automatic shearing machine. The above patent realizes automatic feeding of steel strip, automatic cutting according to predetermined size, and automatic discharge of steel plate. However, the above patent cannot realize the fixing function when cutting metal plate.

[0010] In summary, the aforementioned patents cannot achieve precise adjustment of the shearing machine blade angle, detection of metal plate thickness, adjustment of the shearing machine cutting position, or adjustment of the fixing function during metal plate cutting, resulting in problems such as uneven cutting edges, low processing efficiency, cutting position deviation, and unstable cutting quality.

[0011] Therefore, this application proposes a metal sheet shearing machine that can precisely adjust the blade angle, detect the thickness of the metal sheet, adjust the cutting position, and fix the metal sheet during cutting, and can precisely adjust the processing angle.

[0052] Please see Figure 1 and Figure 2 The present invention provides an embodiment of a metal sheet shearing machine with precisely adjustable processing angle, comprising a multi-angle adjustment module and a shearing machine body 1, wherein the multi-angle adjustment module is installed on the shearing machine body 1, and the multi-angle adjustment module is used to precisely adjust the tilt angle of the shearing machine blade;

[0053] The multi-angle adjustment module includes: a first electric push rod 6, a connecting shaft 7, a fixing frame 8, a first motor 9, and an annular toothed plate 12;

[0054] The shearing machine body 1 is fixedly connected to the top of the outer wall of the base 2. A hydraulic device 3 is installed on the top of the inner wall of the shearing machine body 1. A first connecting frame 4 is fixedly connected to the bottom of the outer wall of the hydraulic device 3. A first electric push rod 6 is symmetrically installed on the first connecting frame 4. A connecting shaft 7 is fixedly connected to the outer wall of the first electric push rod 6. A fixing frame 8 is fitted on the outer wall of the connecting shaft 7. A first rotating rod 14 is fixedly connected to the bottom of the outer wall of the fixing frame 8 by bolts. A rotating shaft 13 is symmetrically fitted on the outer wall of the first rotating rod 14. An annular toothed plate 12 is fixedly connected to the outer wall of the rotating shaft 13. A first motor 9 is fixedly connected to the side wall of the fixing frame 8. A first rotating shaft 10 is installed on the side wall of the first motor 9. A first gear 11 is fixedly connected to the outer wall of the first rotating shaft 10. The first gear 11 meshes with the annular toothed plate 12. A mounting frame 15 is fixedly connected to the bottom of the outer wall of the rotating shaft 13. A shearing blade 16 is fixedly connected to the mounting frame 15 by bolts.

[0055] Furthermore, the first electric push rod 6 is activated, driving the connecting shaft 7 to move up and down. The connecting shaft 7 drives the fixed frame 8 to move, and the fixed frame 8 drives the first rotating rod 14 to move. One of the first electric push rods 6 extends, while the other shortens or remains unchanged, thus differentiating the vertical positions of the two fixed frames 8. The fixed frame 8 rotates on the connecting shaft 7, ensuring its horizontal position remains constant. The different vertical positions of the two fixed frames 8 create an angle between the first rotating rod 14 and the horizontal plane, which in turn creates an angle between the shearing blade 16 and the horizontal plane. When cutting metal plates with inherent angles, precise adjustment of the first electric push rod 6 ensures that the shearing blade 16 is parallel to the metal plate surface, resulting in a more uniform distribution of shearing force on the plate and reducing unnecessary shearing deformation. Stress concentration occurs when the first motor 9 starts, driving the first rotating shaft 10 to rotate. The first rotating shaft 10 drives the first gear 11, which in turn drives the annular toothed plate 12 to rotate. The annular toothed plate 12 drives the rotating shaft 13 to rotate on the first rotating rod 14. The rotating shaft 13 drives the mounting frame 15 to rotate, which in turn drives the shearing blade 16 to rotate, thus adjusting the tilt angle of the shearing blade 16. By adjusting the direction and distribution of the shearing force when the shearing blade 16 contacts the sheet metal, the neatness and smoothness of the cut edge are ensured, reducing burrs and unevenness. The hydraulic device 3 starts, driving the first connecting frame 4 to move. The first connecting frame 4 drives the first electric push rod 6 to move, thereby causing the shearing blade 16 to move up and down. The shearing blade 16 gradually contacts the metal sheet, thus achieving the cutting of the metal sheet.

[0056] Please see Figure 1 and Figure 3The present invention provides an embodiment of a metal sheet shearing machine with a precisely adjustable processing angle. The shearing machine body 1 is equipped with a metal sheet detection module, which is used to detect the thickness of the metal sheet and the height difference between the two sides of the metal sheet, and to calculate the angle between the upper surface of the metal sheet and the horizontal plane.

[0057] The metal plate detection module includes: a distance sensor 17, an intelligent analyzer 18, and a central controller 19;

[0058] Distance sensors 17 are symmetrically fixedly connected to the top of the inner wall of the shearing machine body 1. An intelligent analyzer 18 is fixedly connected to the top of the outer wall of the shearing machine body 1. The distance sensors 17 are connected to the intelligent analyzer 18 via Bluetooth. A central controller 19 is fixedly connected to the side wall of the shearing machine body 1. The central controller 19 is connected to the intelligent analyzer 18 via Bluetooth. The intelligent analyzer 18 is connected to the first electric push rod 6 via Bluetooth. The intelligent analyzer 18 is connected to the first motor 9 via Bluetooth. The intelligent analyzer 18 is connected to the hydraulic device 3 via Bluetooth.

[0059] Furthermore, the staff inputs the relevant hardness data of the metal sheet through the central controller 19. The central controller 19 transmits the hardness data to the intelligent analyzer 18. When the metal sheet is conveyed into the shearing machine body 1, two distance sensors 17 inside the shearing machine body 1 detect the distance between the metal sheet and itself. The distance sensors 17 transmit the detected distance data to the intelligent analyzer 18. The intelligent analyzer 18 receives and analyzes the distance data, compares the two sets of distance data, and determines whether the thickness of the metal sheet is consistent on both sides. When it is determined that the thickness of the metal sheet is consistent on both sides, the intelligent analyzer 18 determines that the metal sheet thickness is uniform. The intelligent analyzer 18 analyzes the thickness of the metal plate based on the distance between the metal plate and the distance sensor 17. Based on the thickness and hardness of the metal plate, the intelligent analyzer 18 controls the first motor 9 to adjust the shearing angle to optimize the cutting effect. When it is determined that the thickness of the two sides of the metal plate is inconsistent, the intelligent analyzer 18 determines that the metal plate itself has a certain angle and analyzes the angle between the upper surface of the metal plate and the horizontal plane. The intelligent analyzer 18 controls the first electric push rod 6 to make the shearing blade 16 parallel to the surface of the metal plate, and then controls the first motor 9 to adjust the shearing angle. The intelligent analyzer 18 starts the hydraulic device 3 to realize the cutting of the metal plate.

[0060] Please see Figure 1 , Figure 2 and Figure 5 The present invention provides an embodiment of a metal sheet shearing machine with a precisely adjustable processing angle. The shearing machine body 1 is equipped with a cutting positioning module, which is used to adjust the horizontal position of the shearing blade 16 and the contact point and cutting trajectory between the shearing blade 16 and the metal sheet.

[0061] The cutting and positioning module includes: a movable plate 20, a first movable groove 21, a movable block 23, a second rotating shaft 24, and a second motor 25;

[0062] The shearing machine body 1 has a first moving groove 21, which is fitted onto the outer wall of the moving plate 20. A hydraulic device 3 is fixedly connected to the bottom of the outer wall of the moving plate 20. A positioning groove 22 is provided on the top of the inner wall of the shearing machine body 1. The positioning groove 22 communicates with the first moving groove 21 and is fitted onto the outer wall of the hydraulic device 3. Moving blocks 23 are symmetrically fixedly connected to the outer wall of the moving plate 20. The first moving groove 21 is fitted onto the outer wall of the moving blocks 23. A second motor 25 is installed inside the shearing machine body 1. A second rotating shaft 24 is installed on the outer wall of the second motor 25. The moving blocks 23 are fitted onto the outer wall of the second rotating shaft 24. The threads of the moving blocks 23 and the second rotating shaft 24 are matched. The second motor 25 is connected to an intelligent analyzer 18 via Bluetooth.

[0063] Furthermore, the intelligent analyzer 18 analyzes the cutting position of the shearing blade 16 and the metal plate based on the tilt angle of the shearing blade 16. The intelligent analyzer 18 controls the second motor 25 to start, the second motor 25 drives the second rotating shaft 24 to rotate, the second rotating shaft 24 drives the moving block 23 to move, the moving block 23 drives the moving plate 20 to move within the first moving groove 21, and the moving plate 20 drives the hydraulic device 3 to move within the positioning groove 22. The movement of the hydraulic device 3 adjusts the position of the shearing blade 16, thereby changing the contact point and cutting trajectory between the shearing blade 16 and the metal plate, ensuring the accuracy of the cutting position. The cutting positioning module adjusts the position of the shearing blade 16 accordingly based on the change in the tilt angle of the shearing blade 16, ensuring the cutting accuracy and effect.

[0064] Please see Figure 1 and Figure 4 The present invention provides an embodiment of a metal sheet shearing machine with a precisely adjustable processing angle. The shearing machine body 1 is equipped with a metal sheet fixing module, which is used to fix the metal sheet when the shearing machine cuts the metal sheet.

[0065] The metal plate fixing module includes: a second electric push rod 26, a second connecting frame 27, a pressing rod 28, a second positioning block 31, a spherical connecting block 32, and a pressing block 33;

[0066] The top of the inner wall of the shearing machine body 1 is symmetrically and fixedly connected to a second electric push rod 26. The bottom of the outer wall of the second electric push rod 26 is fixedly connected to a second connecting frame 27. The intelligent analyzer 18 is connected to the second electric push rod 26 via Bluetooth. Multiple pressure rods 28 are equidistantly installed on the second connecting frame 27. The outer wall of the pressure rod 28 is fixedly connected to a first positioning block 29. A compression spring 30 is fitted on the outer wall of the pressure rod 28. The second connecting frame 27 is located between the first positioning block 29 and the compression spring 30. The bottom of the outer wall of the pressure rod 28 is fixedly connected to a second positioning block 31. The compression spring 30 is located between the second connecting frame 27 and the second positioning block 31. The bottom of the outer wall of the second positioning block 31 is fixedly connected to a spherical connecting block 32. A pressure block 33 is fitted on the outer wall of the spherical connecting block 32. A rubber pad 34 is fixedly connected to the bottom of the outer wall of the pressure block 33.

[0067] Further, the metal plate is fed into the shearing machine body 1. Before cutting the metal plate, the second electric push rod 26 is activated. The second electric push rod 26 drives the second connecting frame 27 to move, gradually bringing the second connecting frame 27 closer to the metal plate. The second connecting frame 27 drives the pressure rod 28 to move, the pressure rod 28 drives the second positioning block 31 to move, the second positioning block 31 drives the spherical connecting block 32 to move, the spherical connecting block 32 drives the pressure block 33 to move, and the pressure block 33 drives the rubber pad 34 to move, gradually bringing the rubber pad 34 into contact with the metal plate. After the rubber pad 34 is tightly in contact with the metal plate, the second electric push rod 26... The second connecting frame 27 continues to move closer to the metal plate. The second connecting frame 27 moves downward along the pressure bar 28. The second connecting frame 27 gradually squeezes the compression spring 30. The compression spring 30 squeezes the second positioning block 31. The elastic force causes the pressure applied to the metal plate by the rubber pad 34 to gradually increase, thereby achieving stable fixation of the metal plate. If the metal plate itself has a certain angle, the pressure block 33 will rotate outside the spherical connecting block 32 under the action of force until the rubber pad 34 is in close contact with the metal plate. The rubber pad 34 avoids direct contact between the pressure block 33 and the metal plate, providing a buffering effect and preventing deformation of the metal plate.

A feeding mechanism is mounted on the base 2 for automatically transporting metal sheets.

The fourth motor 45 is connected to the transmission wheel 46 via a rotating shaft, and the transmission belt 47 is fitted onto the outer wall of the transmission wheel 46. A cleaning mechanism is mounted on the base 2 for cleaning dust from the surface of the metal sheets. The cleaning mechanism includes: a fixed bracket 48, an adjusting block 49, a second rotating rod 50, a dust removal brush 51, and a first spring 53; the fixed bracket 48 is symmetrically fixedly connected to the top of the outer wall of the base 2, the side wall of the fixed bracket 48 is provided with an adjusting groove 52, the adjusting groove 52 is fitted into the adjusting block 49, the top of the outer wall of the adjusting block 49 is fixedly connected to the first spring 53, the top of the outer wall of the first spring 53 is fixedly connected to the fixed bracket 48, the first spring 53 is installed in the adjusting groove 52, the adjusting block 49 is fitted into the second rotating rod 50, and the outer wall of the second rotating rod 50 is fixedly connected to the dust removal brush 51;

[0069] Furthermore, the worker places the metal sheet on the transmission belt 47, and the fourth motor 45 on the mounting base 44 is started. The fourth motor 45 drives the transmission wheel 46 to rotate through the rotating shaft. The transmission wheel 46 drives the transmission belt 47 to rotate, and the transmission belt 47 moves the metal sheet, realizing automatic feeding of the metal sheet. The metal sheet is transferred to the base 2 and passes under the dust removal brush 51. The first spring 53 in the adjusting groove 52 applies a downward elastic force to the adjusting block 49. The adjusting block 49 applies a downward pressure to the second rotating rod 50. The second rotating rod 50 applies a downward pressure to the dust removal brush 51, so that the dust removal brush 51 is in close contact with the metal sheet. During the process of the metal sheet passing through the dust removal brush 51, the dust removal brush 51 cleans the dust and impurities on the surface of the metal sheet, realizing automatic cleaning of dust and impurities on the surface of the metal sheet during the transmission process. This avoids dust and impurities on the surface of the metal sheet being rolled between the shearing blade 16 and the metal sheet during the cutting process, which would cause burrs, unevenness and other problems on the cutting edge.

[0070] Please see Figure 1 , Figure 6 and Figure 7An embodiment of the present invention provides a metal sheet shearing machine with precisely adjustable processing angle. The shearing machine body 1 has a second bracket 60 symmetrically fixedly connected to its outer wall. A fifth motor 59 is fixedly connected to the outer wall of the second bracket 60. A fourth rotating shaft 58 is installed on the side wall of the fifth motor 59. The shearing machine body 1 is fitted onto the outer wall of the fourth rotating shaft 58. A third gear 57 is fixedly connected to the side wall of the fourth rotating shaft 58. A sliding groove 54 is symmetrically opened inside the shearing machine body 1. The sliding groove 54 is fitted onto the outer wall of a sliding block 55. A third toothed plate 56 is fixedly connected to the outer wall of the sliding block 55, and the third toothed plate 56 meshes with the third gear 57. A sixth motor 61 is fixedly connected to the top of the outer wall of the sliding block 55. The sixth motor 61 is fixedly connected to a rotating block 62 via a rotating shaft. The outer wall of the rotating block 62 is fitted with the sliding block 55. A pressure sensor 63 is fixedly connected to the side wall of the rotating block 62. The pressure sensor 63 is connected to a fourth motor 45 via Bluetooth and to an intelligent analyzer 18 via Bluetooth.

[0071] Furthermore, the fifth motor 59 on the second support 60 is activated. The fifth motor 59 drives the fourth rotating shaft 58 to rotate, which in turn drives the third gear 57 to rotate. The third gear 57 drives the third toothed plate 56, which meshes with it, to move. The third toothed plate 56 then drives the sliding block 55 to move, causing the sliding block 55 to move within the sliding groove 54. The sliding block 55 drives the sixth motor 61 and the rotating block 62 to move, thereby changing the distance between the rotating block 62 and the shearing machine body 1. The moving distance of the sliding block 55 is adjusted according to the required size of the metal plate to be cut, thus changing the distance between the rotating block 62 and the shearing machine body 1. The sixth motor 59 is then activated. 1. The sixth motor 61 drives the rotating block 62 to rotate via the rotating shaft. The rotation angle of the rotating block 62 is adjusted so that the rotating block 62 is parallel to the metal plate. During the transmission process, the metal plate gradually approaches the rotating block 62 and comes into contact with the pressure sensor 63. After the pressure sensor 63 detects the pressure, it controls the fourth motor 45 to shut down, stopping the transmission of the metal plate. The rotating block 62 then contacts the metal plate, positioning it and adjusting it to a suitable cutting position so that the cut metal plate meets the specified dimensions. The adjustment of the rotation angle of the rotating block 62 allows the shearing machine to adapt to metal plates of different shapes.

[0072] Working principle: The third motor 39 on the first bracket 40 is started. The third motor 39 drives the second gear 37 through the third rotating shaft 38. The second gear 37 drives the first toothed plate 36. The first toothed plate 36 drives the guide block 35. The guide block 35 drives the guide frame 41. The guide frame 41 drives the connecting rod 42 and the guide wheel 43. The guide wheel 43 is adjusted to a suitable position. The feeding mechanism transmits the metal plate into the shearing machine body 1. The cleaning mechanism cleans the dust and impurities on the surface of the metal plate during the transmission process. After the metal plate enters the shearing machine body 1, the guide wheel 43 guides the metal plate to avoid misalignment during the transmission process.

[0073] The metal plate enters from one side of the shearing machine body 1 and exits from the other side. The rotating block 62 contacts the metal plate. After the pressure sensor 63 on the rotating block 62 detects the pressure, the pressure sensor 63 controls the fourth motor 45 to shut down, stopping the feeding mechanism. After receiving the pressure signal transmitted by the pressure sensor 63, the intelligent analyzer 18 starts the second electric push rod 26 to fix the metal plate. The intelligent analyzer 18 controls the first motor 9 and the first electric push rod 6 to adjust the angle of the shearing blade 16. According to the tilt angle of the shearing blade 16, the intelligent analyzer 18 starts the second motor 25 to adjust the position of the shearing blade 16 to ensure the accuracy of the cutting position. The hydraulic device 3 is started, and the first connecting frame 4 moves in the second moving groove 5 to realize the cutting of the metal plate.

[0074] The seventh motor 64 starts, and the seventh motor 64 drives the third rotating rod 65 to rotate. The third rotating rod 65 drives the rotating plate 66 to rotate. The rotating plate 66 on the base 2 rotates from the horizontal position to the vertical position. After the metal plate on the rotating plate 66 loses its support, it falls into the placement groove 69 and onto the placement plate 67. The second spring 68 cushions the placement plate 67. The worker takes out the cut metal plate from the discharge groove 70 on the side wall of the base 2.
