Description

Technical Field

[0001] The invention relates to the technical field of non-ferrous metal plates, in particular to a shearing system for producing non-ferrous metal plates. Background Art

[0002] Nonferrous metal sheets refer to plate-like products made of nonferrous metal materials. Nonferrous metals refer to metals other than iron, manganese and chromium, which usually have good electrical conductivity, thermal conductivity and corrosion resistance. Nonferrous metal sheets are usually in the form of flat plates with a certain thickness, width and length. They can be thin plates, medium plates or thick plates, depending on the application scenario and processing requirements. Nonferrous metal sheets can be made through a variety of processing techniques, such as rolling, extrusion, and stretching, which affect the microstructure and mechanical properties of the sheet. Due to their good corrosion resistance and other characteristics, nonferrous metal sheets are suitable for use in various environmental conditions, including high temperature, high pressure and chemical corrosion environments. Nonferrous metal sheets need to be sheared during processing.

[0003] After searching, it was found that there were problems in the shearing process of non-ferrous metal sheets in the prior art. During the shearing process of non-ferrous metal sheets, the part of the non-ferrous metal sheet that exceeds the shearing knife is the part that needs to be sheared. It is difficult for the existing shearing machine to apply tension to this part of the non-ferrous metal sheet, resulting in uneven cuts due to the non-ferrous metal sheet not being tightened during the shearing process. In addition, the shearing gap is also an important factor affecting the shearing effect. A gap that is too small may lead to excessive extrusion and burrs, while a gap that is too large may lead to incomplete shearing, resulting in torn or uneven edges, further affecting the shearing effect of the non-ferrous metal sheet. Therefore, based on the above search and combined with the prior art, a shearing system for non-ferrous metal sheet production is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

The shear gap is related to the thickness of the non-ferrous metal sheet. Thicker sheets may require a larger shear gap to reduce the resistance and load on the tool during shearing, while thinner sheets require a smaller shear gap to obtain a finer shear edge. The calculation formula of shear stress is shear stress (τ) = total shear force (V) / [moment of inertia (I) × thickness (t) × first moment of area (Q)], where thickness (t) is the material thickness at the point of interest. This formula can indirectly reflect the relationship between the shear gap and the thickness of non-ferrous metal sheets; A connecting block 26 is fixedly installed on one side of the shearing knife 18, a connecting hole 25 is opened on one side of the fixing frame 17, one side of the connecting block 26 passes through the connecting hole 25 and extends to the outside of the fixing frame 17, two connecting frames 21 are fixedly installed on one side of the fixing frame 17, a measuring plate 22 is slidably connected between the two connecting frames 21, a scale is opened on one side of the measuring plate 22, the measuring plate 22 is slidably connected to the connecting block 26, screws 27 for locking the connecting block 26 are installed on both sides of the connecting block 26, a plurality of thread grooves are opened on both sides of the measuring plate 22, the screws 27 pass through the connecting block 26 and are threadedly connected to the inner circumferential wall surface of the thread groove; Here, the shearing gap between the shearing knife 18 and the shearing knife 2 57 is determined according to the thickness of the non-ferrous metal sheet, and the shearing knife 18 is driven to move by moving the connecting block 26 until a suitable shearing gap is reached, and then the position of the shearing knife 18 is locked by the screw 27; A top plate 62 is fixedly installed on one side of the upper connection frame 21, and a movable plate 23 is rotatably connected to one side of the top plate 62. A threaded column 36 is fixedly installed on one side of the movable plate 23. One end of the threaded column 36 passes through the top plate 62 and extends to the outside of the top plate 62, and a nut is threadedly connected to the outer wall surface. A support shaft 32 is fixedly installed on one side of the movable plate 23. Two base blocks 28 are fixedly installed on one side of the connecting block 26. A movable plate 2 59 is rotatably connected between the two base blocks 28 through a rotating shaft. The support shaft 32 is slidably connected to the connecting block 26.

By rotating the movable plate 1 23 to drive the position of the support shaft 32 in the arc hole 31 on the connecting block 26, the position of the fulcrum when the connecting block 26 rotates is changed, thereby changing the travel of the shearing knife 18. The shearing mechanism 7 also includes two fixed plates 10, both of which are fixedly mounted on the top surface of the base plate 1, one side of the support plate 6 is rotatably connected to the fixed plate 10 via a rotating shaft, a connecting plate 19 is fixedly mounted between the two fixed plates 10, a mounting plate 9 is provided on the top surface of the base plate 1, and an electric push rod 41 for driving the mounting plate 9 to move is fixedly mounted on one side of the connecting plate 19, one end of the telescopic shaft of the electric push rod 41 is fixedly connected to one side of the mounting plate 9, A tension dynamometer 42 is fixedly mounted on one side of the connecting plate 19, and a clamp on the tension dynamometer 42 is connected to one side of the mounting plate 9. The tension dynamometer 42 can measure the tension when the electric push rod 2 41 drives the mounting plate 9 to move outward. Two mounting frames 43 are fixedly installed on one side of the mounting plate 9, and an electric push rod 3 48 is fixedly installed inside the mounting frame 43. One end of the telescopic shaft of the electric push rod 3 48 passes through the mounting frame 43 and extends to the outside of the mounting frame 43. A positioning block 51 is fixedly installed on one end of the telescopic shaft of the electric push rod 3 48. Both sides of the positioning block 51 are rotatably connected with connecting rods 52 through rotating shafts. Support rods 53 are symmetrically arranged on the top and bottom surfaces of the positioning block 51. One end of the connecting rod 52 is rotatably connected to one side of the support rod 53 through the rotating shaft. A chuck 55 is fixedly installed on one side of the support rod 53, and the inside of the chuck 55 is fixedly connected to the support rod 53. A rubber block 56 is fixedly installed, and the rubber block 56 is used to increase the friction between the chuck 55 and the non-ferrous metal plate. Two cover plates 49 are fixedly installed on one side of the installation frame 43, and a limiting column 54 is fixedly installed on one side of the support rod 53. A limiting hole 50 for limiting the support rod 53 is opened on one side of the cover plate 49, and the limiting column 54 is slidably connected with the limiting hole 50. A PLC controller is fixedly installed on the top surface of the base plate 1, and the electric roller 1 8, the electric roller 2 16, the drive motor 1 29, the electric push rod 2 41, the tension dynamometer 42 and the electric push rod 3 48 are all electrically connected to the PLC controller; Among them, non-ferrous metal sheets have a certain degree of ductility, which can be quantified by mathematical formulas; one is the elongation (elongation), which is an indicator that describes the plastic properties of the material and indicates the degree of plastic deformation that the material can withstand before breaking. The calculation formula for elongation is: elongation (%) = TD / D, where T is the length after breaking and D is the original gauge length; The second is the percentage of area reduction. The percentage of area reduction is another way to express ductility. It is calculated by measuring the change in the cross-sectional area of ​​the material during the stretching process. The calculation formula is: percentage of area reduction = AB / A, where A is the original cross-sectional area and B is the cross-sectional area at the fracture point. These formulas provide a method to quantify the ductility of non-ferrous metal sheets. Elongation and percentage reduction in area are commonly used parameters in materials science to evaluate the plastic deformation capacity of materials when subjected to tensile forces. Through these parameters, the ductility of different materials or under different processing conditions can be compared, thus providing a basis for material selection and processing. By quantifying the ductility of the non-ferrous metal sheet, the maximum tensile force that the non-ferrous metal can withstand without being stretched is obtained, and the tensile force is set as a predetermined value of the tensile force gauge 42 and measured by the tensile force gauge 42; The telescopic shaft of the electric push rod 3 48 moves outward to drive the positioning block 51 to move outward, and the positioning block 51 moves outward to drive the connecting rod 52 to rotate inward. The connecting rod 52 rotates inward so that the support rod 53 drives the chuck 55 to move inward to clamp one end of the non-ferrous metal sheet. Then, the electric push rod 2 41 drives the mounting plate 9 and the support rod 53 and the chuck 55 to move outward to apply tension to the non-ferrous metal sheet. When the tension reaches a predetermined value, the shear knife 18 and the shear knife 2 57 cooperate to shear the non-ferrous metal sheet to improve the shearing effect. With the above technical solution, the staff uses the uncoiler 3 to unwind the nonferrous metal steel coil, and the unwinding nonferrous metal sheet enters the inside of the flattening machine 4 for flattening. The flattened nonferrous metal sheet moves forward after being transported by multiple electric rollers 16. At this time, multiple electric rollers 8 can also further transport the nonferrous metal sheet. The part of the nonferrous metal sheet that exceeds the shearing knife 18 is the part that needs to be sheared. The nonferrous metal sheet stops moving when it reaches the distance required for shearing. The staff adjusts the shearing gap between the shearing knife 18 and the shearing knife 2 57 according to the thickness of the non-ferrous metal sheet. The staff moves the connecting block 26 so that the connecting block 26 moves along the measuring plate 22. The staff moves the connecting block 26 and the shearing knife 18 to a suitable position according to the scale on the measuring plate 22. The staff uses the screw 27 to lock the position of the connecting block 26 and the shearing knife 18, and balances the shearing gap with the thickness of the non-ferrous metal sheet. A reasonable shearing gap can ensure that the non-ferrous metal sheet is cut cleanly and neatly, thereby improving the shearing effect. At the same time, the staff rotates the movable plate 1 23, and the rotation of the movable plate 1 23 drives the threaded column 36 to rotate on the top plate 62. The rotation of the movable plate 1 23 drives the support shaft 32 to slide inside the arc hole 31 on the movable plate 2 59. The movement of the support shaft 32 changes the fulcrum position of the connection block 26, thereby adjusting the rotation distance of the connection block 26, and then adjusting the movement stroke of the shearing knife 1 18 so that it matches the shearing gap between the shearing knife 1 18 and the shearing knife 2 57, so as to prevent the shearing knife 2 57 and the shearing knife 1 18 from colliding or the non-ferrous metal sheet from not being sheared due to the adjustment of the shearing gap between the shearing knife 1 18 and the shearing knife 2 57. In addition, the maximum tensile force that the nonferrous metal sheet can withstand without extension can be obtained through calculation, and the staff uses this tensile force as the predetermined value of the tensile force measuring instrument 42; The PLC controller starts the electric push rod 3 48, and the telescopic shaft of the electric push rod 3 48 moves outward to drive the positioning block 51 to move outward. The positioning block 51 moves outward to drive the connecting rod 52 to rotate inward. The connecting rod 52 rotates inward so that the support rod 53 drives the clamp 55 to move inward. The support rod 53 moves inward to drive the limit column 54 to slide inside the limit hole 50 of the cover plate 49. The limit hole 50 and the limit column 54 cooperate to limit the movement of the support rod 53. The two clamps 55 move inward to clamp one end of the non-ferrous metal plate. The PLC controller starts the electric push rod 2 41, and the telescopic shaft of the electric push rod 2 41 moves outward to drive the mounting plate 9 to move outward, and the mounting plate 9 moves outward to drive the two sets of clamps 55 and the non-ferrous metal sheet clamped therein to move outward, thereby applying a pulling force to the side of the non-ferrous metal sheet that exceeds the shear knife 18, which is also a tensioning force that tightens the non-ferrous metal sheet. The tension force measuring instrument 42 can measure this pulling force; When the tension applied by the electric push rod 41 reaches the preset value of the tension dynamometer 42, the telescopic shaft of the electric push rod 41 stops moving outward. At this time, the non-ferrous metal sheet is tightened under the action of the tension, which prevents the shearing from being affected by the lack of tension at one end of the non-ferrous metal sheet, thus helping to reduce the shearing force requirement, improve the shearing quality, and ensure a smooth shearing edge. Then, the PLC controller starts the driving motor 29, the driving shaft of the driving motor 29 rotates to drive the worm 30, the worm 30 rotates to drive the worm wheel 61, the worm wheel 61 rotates to drive the mounting rod 60, the mounting rod 60 rotates to drive the movable plate 2 59 to rotate, the movable plate 2 59 rotates around the supporting shaft 32 to drive the connecting block 26 to move up and down through the base block 28, the connecting block 26 moves up and down to drive the shearing knife 18 to move up and down, and at the same time, the measuring plate 22 moves between the two connecting frames 21, and the intermittent up and down movement of the shearing knife 18 can shear the non-ferrous metal plate; In this process, firstly, the gap between the shearing knife 18 and the shearing knife 2 57 is adjusted according to the thickness of the non-ferrous metal sheet to achieve a balance between the shearing gap and the thickness of the non-ferrous metal sheet. The appropriate shearing gap can ensure that the non-ferrous metal sheet is cut cleanly and burrs and tears are reduced. Secondly, by providing tension to the non-ferrous metal sheet to make it reach the state before extension and then shearing, it can prevent the deformation of the non-ferrous metal sheet and reduce the shear force demand, improve the shearing quality, avoid fracture during the shearing process, improve the microstructure and grain size of the material, reduce residual stress, and improve material utilization, which helps to optimize the shearing process, achieve the shearing effect of the non-ferrous metal sheet, and facilitate the workers to shear the non-ferrous metal sheet; Two support tubes 44 are fixedly installed on one side of the connecting plate 19. A limiting column 45 for limiting the movement of the mounting plate 9 is slidably connected inside the support tube 44. One side of the limiting column 45 is fixedly connected to one side of the mounting plate 9. The movement of the mounting plate 9 causes the limiting column 45 to move outward inside the support tube 44. The support tube 44 and the limiting column 45 cooperate to limit the movement of the mounting plate 9. Specifically, by setting up the mounting plate 9, the mounting plate 9 moves outward to drive the limiting column 45 to move outward inside the support tube 44. The support tube 44 and the limiting column 45 cooperate to limit the movement of the mounting plate 9 to prevent the mounting plate 9 from shaking during the outward movement.

At the same time, the driving shaft of the driving motor 2 58 rotates to drive the gear 2 40 to rotate, the gear 2 40 rotates to drive the gear 1 39 to rotate, and the gear 1 39 rotates to drive the smart camera 38 to rotate, thereby adjusting the angle of the smart camera 38, and then allowing the smart camera 38 to perform a comprehensive visual inspection on the sheared non-ferrous metal sheet; A plurality of fixed blocks 11 are fixedly mounted on the top surface of the base plate 1, and a movable block 12 is rotatably connected between every two fixed blocks 11 through a rotating shaft, and an electric push rod 13 is fixedly mounted on one side of the movable block 12, and one end of the telescopic shaft of the electric push rod 13 is rotatably connected to the bottom surface of the support plate 6 through a universal joint, and the electric push rod 13 is electrically connected to the PLC controller; After the non-ferrous metal sheet is sheared, the telescopic shaft of the electric push rod 13 moves inward to drive the support plate 6 and the electric roller 8 to rotate downward, and the support plate 6 and the electric roller 8 rotate downward so that the sheared non-ferrous metal sheet is discharged along the inclined electric roller 8; Specifically, the sheared nonferrous metal sheets fall on a plurality of electric rollers 8 through the electric rollers 8, and the telescopic shaft of the electric push rod 13 moves inward to drive the support plate 6 and the electric roller 8 to rotate downward around the fixed plate 10, and at the same time, the movable block 12 rotates between the two fixed blocks 11. At this time, the nonferrous metal sheets on the electric rollers 8 fall along the inclined electric rollers 8, and then the support plate 6 and the electric rollers 8 are reset, thereby unloading the nonferrous metal sheets on the electric rollers 8; A collecting box 14 is connected between the two support frames 15 by bolts, and a collecting box 2 15 is connected between the two support frames 15 by bolts. The collecting box 2 15 is used to collect non-ferrous metal sheets that fail to be sheared, and the collecting box 14 is used to shear qualified non-ferrous metal sheets; Specifically, through the intelligent camera 38, when the intelligent camera 38 detects that the non-ferrous metal sheet after shearing on the electric roller 8 is unqualified, the telescopic axis of the electric push rod 13 moves inwardly with a small amplitude so that the support plate 6 and the electric roller 8 rotate downward with a small amplitude. At this time, the non-ferrous metal sheet after shearing that is unqualified enters the interior of the collection box 2 15 along the inclined support plate 6 and the electric roller 8. In addition, when the intelligent camera 38 detects that the non-ferrous metal sheet after shearing is qualified, the support plate 6 and the electric roller 8 rotate downward with a large amplitude, so that the non-ferrous metal sheet after shearing that is qualified enters the interior of the collection box 14, thereby classifying the non-ferrous metal sheet after shearing; A support groove 33 is provided on one side of the fixing frame 17, and a support frame 2 34 is fixedly installed on one side of the shearing knife 18.

[0019] As a preferred implementation in this embodiment, please refer to Figures 1 to 8 , a shearing system for producing non-ferrous metal sheets, comprising the following steps: Step 1: Uncoiling and leveling. The equipment includes an uncoiling machine 3 and a leveling machine 4, which are used to unroll the coiled non-ferrous metal sheet into a flat plate and perform leveling to ensure that the sheet reaches the required flatness before shearing. Step 2: conveying and shearing. The equipment conveys the non-ferrous metal sheet through the electric roller 2 16 and the electric roller 1 8. The shearing mechanism 7 includes a fixing frame 17, a shearing knife 18, a shearing knife 57 and a positioning plate 20, which are used for accurately shearing the non-ferrous metal sheet. It also includes a tensile force gauge 42, which is used to apply tension to the non-ferrous metal sheet before shearing, so that it reaches the state before extension occurs, thereby improving the shearing effect. Step 3: Shear gap adjustment. The shear gap is the vertical distance between shear blade 18 and shear blade 2 57. It can be adjusted according to the thickness of the plate to ensure the shearing quality. Step 4: Adjust the shearing knife stroke. By cooperating with the movable plate 23 and the support shaft 32, adjust the moving stroke of the shearing knife 18 to prevent the shearing knife 18 from hitting the shearing knife 2 57 or failing to cut the plate. Step 5: Visual inspection. The intelligent camera 38 is used to perform visual inspection on the sheared nonferrous metal sheets to detect whether there are defects in the cut. The collecting box 14 and the collecting box 2 15 are used to collect the qualified and unqualified sheared nonferrous metal sheets respectively. The sheared nonferrous metal sheets are unloaded through the inclined electric roller 18, and the unloading process is controlled by the electric push rod 13.

[0020] This system integrates multiple functional modules to achieve automated cutting and processing of non-ferrous metal sheets, improving production efficiency and cutting quality. At the same time, it ensures the consistency of product quality through visual inspection and classification collection.

[0021] Working principle: Through the uncoiler 3, the staff uses the uncoiler 3 to unwind the non-ferrous metal steel coil, and the unwinding non-ferrous metal sheet enters the inside of the flattening machine 4 for flattening. The flattened non-ferrous metal sheet is transported forward through multiple electric rollers 16 and 8; The shearing gap between the shearing knife 18 and the shearing knife 2 57 is determined according to the thickness of the non-ferrous metal sheet, and the shearing knife 18 is driven to move by moving the connecting block 26 until a suitable shearing gap is reached, and then the position of the shearing knife 18 is locked by the screw 27; The driving motor 1 29 drives the worm 30 and the worm wheel 61 to rotate, the rotation of the worm wheel 61 drives the mounting rod 60 to rotate, the rotation of the mounting rod 60 causes the movable plate 2 59 to rotate up and down around the fulcrum support shaft 32, the connecting block 26 moves up and down to drive the measuring plate 22 and the connecting block 26 to move up and down, the connecting block 26 moves up and down to drive the shearing knife 1 18 to move up and down, the shearing knife 18 moves up and down and cooperates with the shearing knife 2 57 to shear the non-ferrous metal plate; In addition, after adjusting the shearing gap between the fixing frame 17 and the shearing knife 2 57, it is also necessary to adjust the travel of the shearing knife 18 to prevent the shearing knife 18 from hitting the shearing knife 2 57 or failing to cut the non-ferrous metal sheet. By rotating the movable plate 1 23 to drive the position of the support shaft 32 in the arc hole 31 on the connecting block 26, the position of the fulcrum when the connecting block 26 rotates is changed, thereby changing the travel of the shearing knife 18. By quantifying the ductility of the non-ferrous metal sheet, the maximum tensile force that the non-ferrous metal can withstand without being stretched is obtained, and the tensile force is set as a predetermined value of the tensile force gauge 42 and measured by the tensile force gauge 42; At the same time, the telescopic shaft 48 of the electric push rod 3 moves outward to drive the positioning block 51 to move outward, and the positioning block 51 moves outward to drive the connecting rod 52 to rotate inward. The connecting rod 52 rotates inward so that the support rod 53 drives the chuck 55 to move inward to clamp one end of the non-ferrous metal sheet. Then, the electric push rod 2 41 drives the mounting plate 9 and the support rod 53 and the chuck 55 to move outward to apply tension to the non-ferrous metal sheet. When the tension reaches a predetermined value, the shear knife 18 and the shear knife 2 57 cooperate to shear the non-ferrous metal sheet to improve the shearing effect. Next, the smart camera 38 can perform visual inspection on the sheared nonferrous metal sheet to detect whether there are defects in the cut, and the drive motor 2 58 drives the gear 2 40 to rotate, and the rotation of the gear 2 40 drives the gear 1 39 and the positioning plate 2 37 to rotate, thereby adjusting the angle of the smart camera 38; Finally, after the non-ferrous metal sheet is sheared, the telescopic axis of the electric push rod 13 moves inward to drive the support plate 6 and the electric roller 8 to rotate downward. The support plate 6 and the electric roller 8 rotate downward so that the sheared non-ferrous metal sheet is discharged along the inclined electric roller 8.
