Description

Technical Field

[0001] The invention belongs to the technical field of steel plate shearing, in particular to a steel plate shearing device with an automatic leveling function. Background Art

[0002] Steel flattening is a common operation in steel processing. It is mainly used to unfold the steel coil into a flat plate for subsequent processing. The operator needs to place the steel coil on the drum of the flattening machine, flatten the steel plate from the coil, and then divide the flattened steel plate into sections and cut them into the required size for processing;

[0003] Currently, traditional steel plate shearing equipment unwinds coiled steel plates. This process typically involves using an unwinding device to gradually release the tightly coiled steel plate, restoring it to a flatter, flattened form. The unwound steel plate is then placed on a conveyor assembly, typically consisting of a series of rollers or conveyor belts. A motor-driven conveyor drives the steel plate toward the shear assembly. Once the steel plate reaches the designated location, a sharp blade or shearing tool is used to shear the plate to the desired dimensions and specifications, ultimately producing a finished steel plate that meets specifications.

[0004] However, in actual use, despite certain precautions taken when unfolding the steel sheets, they are still prone to bending. This bending is caused by a variety of factors. Firstly, during long-term storage and transportation, the coiled steel sheets accumulate significant deformation energy due to their own gravity and the stress generated during coiling. Once unfolded, this energy is released, causing the steel sheets to bend. This bending can lead to a series of serious problems and significantly reduce shear quality. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1 to 7 As shown, the present invention provides a steel plate shearing device with an automatic leveling function, comprising a main body 1 and a shearing box 2, and further comprising:

[0036] a shearing assembly 3, which is disposed inside the shearing box 2;

[0037] a leveling mechanism 4 , which is arranged inside the shear box 2 ;

[0038] Among them, the leveling mechanism 4 includes a square shell 401 fixedly connected to the inside of the shear box 2, and the inside of the square shell 401 is slidably connected to a sliding rod 402, and the top of the sliding rod 402 is fixedly installed with a mounting plate 403, and the inside of the mounting plate 403 is rotatably connected to an extrusion wheel 404. There are two gears 405 rotating on both sides of the inside of the shear box 2, and the two gears 405 are engaged with each other. One side of the gear 405 is fixedly installed with a push rod 406 located inside the sliding rod 402, and the sliding rod 402 can slide inside the push rod 406. Motors 407 are fixedly installed on both sides of the outer surface of the shear box 2, and the output end of the motor 407 extends to the inside of the shear box 2 and is fixedly connected to the surface of the gear 405.

[0039] The above scheme is adopted: the operator unfolds the rolled steel plate and places the unfolded end on the top of the main body 1, then the conveyor roller on the top of the main body 1 drives the steel plate to move to the inside of the shear box 2, and then drives the two motors 407 to rotate the gear 1 405. Since the two gears 1 405 are engaged with each other, the rotating gear 1 405 will drive the other gear 1 405 to rotate, and then the two gears 1 405 will drive the push rod 406 to rotate, and the sliding rod 402 will slide inside the push rod 406, and then the rotating push rod 406 will push the sliding rod 402 to descend, and the sliding rod 402 will drive the mounting plate 403 and the extrusion wheel 404 to descend, and then the extrusion The pressing wheel 404 will come into contact with the moving steel plate, thereby squeezing the steel plate to level the bent steel plate, and the moving steel plate will drive the squeezing wheel 404 to rotate, and will not interfere with the movement of the steel plate. When the steel plate moves to the position where shearing is required, the shearing component 3 can be driven to shear the steel plate. Finally, the driving motor 407 is used to make the push rod 406 push the squeezing wheels 404 on both sides of the shearing component 3 to squeeze the steel plate, so that the squeezing wheels 404 apply uniform and appropriate pressure to the steel plate from both sides simultaneously, squeeze and level the steel plate, effectively eliminate the internal stress and bending deformation of the steel plate, significantly improve the flatness of the steel plate, provide high-quality plates for subsequent shearing and other processing procedures, and ensure the overall production quality.

[0040] like Figure 6 and Figure 7 As shown, it also includes:

[0041] The drive assembly 5 is disposed inside the main body 1 and includes a rack 501 slidably connected to the main body 1. Sealing plates 502 are fixedly mounted on both sides of the rack 501. The sealing plates 502 are elastically connected to the main body 1 via an elastic member 503. An extrusion rod 504 is fixedly mounted on the bottom end of the mounting plate 403.

[0042] The positioning mechanism 6 is arranged inside the main body 1 .

[0043] The above solution is adopted: through the design of the driving component 5, when the mounting plate 403 descends, the extrusion rod 504 will be linked to move downward, and then the extrusion rod 504 will enter the interior of the main body 1 and promote the flow of gas inside the main body 1, and the flowing gas will push the sealing plate 502 and the rack 501 to move. When the sealing plate 502 moves, the elastic member 503 will be stretched, and the elastic member 503 will be restored by using its resilience, so as to pull the rack 501 and the sealing plate 502 to reset. Then the moving rack 501 will drive the positioning mechanism 6 to move toward the surface of the steel plate, and then position the steel plate.

[0044] like Figure 6 and Figure 7As shown, the positioning mechanism 6 includes a gear 2 601 rotatably connected to the inside of the main body 1, a screw rod 602 is fixedly installed on one side of the gear 2 601, a threaded plate 603 is threadedly sleeved on the surface of the screw rod 602, a square plate 604 is fixedly installed on the top of the threaded plate 603, an elastic member 2 605 is fixedly installed on one side of the square plate 604, and a positioning plate 606 is fixedly installed on one end of the square plate 604.

[0045] The above scheme is adopted: through the design of the positioning mechanism 6, when the rack 501 moves, because the rack 501 is engaged with the gear 2 601, the rack 501 will drive the gear 2 601 to rotate, and the gear 2 601 will drive the screw rod 602 to rotate. Since the screw rod 602 is threadedly connected to the threaded plate 603, the threaded plate 603 will move on the surface of the screw rod 602, and the threaded plate 603 will drive the square plate 604, the elastic member 2 605 and the positioning plate 606 to move toward the surface of the steel plate, and the positioning plate 606 will contact the surface of the steel plate and push the steel plate to move. At the same time, the elastic member 2 605 will shrink and will not interfere with the lowering of the mounting plate 403 and the extrusion wheel 404. Then, when the four positioning plates 606 contact the steel plate at the same time, the steel plate can be positioned in the middle of the top of the main body 1. Finally, the rack 501 drives the gear 2 601 to make the four positioning plates 606 contact the steel plate at the same time from different directions, exerting a uniform and appropriate force on the steel plate. With their coordinated cooperation, the steel plate is quickly and accurately positioned to the middle position of the top of the main body 1, effectively avoiding the deviation of the steel plate, laying the foundation for the subsequent leveling and precise shearing processes, and greatly improving the shearing quality.

[0046] like Figure 3 and Figure 4 As shown, the shearing assembly 3 includes an electric push rod 301 fixedly connected to the inside of the shearing box 2, and a shearing blade 302 is fixedly installed on the output shaft of the electric push rod 301.

[0047] Adopting the above solution: through the design of the shearing component 3, when the steel plate is leveled and moved to the position where shearing is required, the electric push rod 301 can be driven so that its output shaft pushes the shearing blade 302 down, and then the shearing blade 302 will contact the surface of the steel plate and then shear it.

[0048] like Figure 7 As shown, it also includes:

[0049] The fixing component 7 is arranged on one side of the positioning plate 606. The fixing component 7 is fixedly connected to the connecting plate 701 on one side of the positioning plate 606. The top of the connecting plate 701 is fixedly installed with a cylinder 702. The output end of the cylinder 702 passes downward through the connecting plate 701 and is fixedly installed with a fixing plate 703.

[0050] Adopting the above solution: through the design of the fixing component 7, when the steel plate is leveled and moved to the position where shearing is required, the cylinder 702 can be driven so that its output shaft pushes the fixing plate 703 down, and then the bottom end of the fixing plate 703 will contact the surface of the steel plate, thereby fixing the steel plate and ensuring the stability of the shearing.

[0051] like Figure 7 As shown, it also includes:

[0052] The limiting component 8 is arranged inside the main body 1. The limiting component 8 includes a slide groove 801 that is opened inside the main body 1. The internal sliding connection of the slide groove 801 is a limiting block 802, and one end of the limiting block 802 is fixedly connected to the surface of the threaded plate 603.

[0053] Adopting the above-mentioned scheme: through the design of the limiting component 8, during the movement of the threaded plate 603, the limiting block 802 will be driven to slide inside the slide groove 801. Since the surface of the limiting block 802 fits with the inner wall of the slide groove 801, the threaded plate 603 can be limited to ensure stable movement.

[0054] like Figure 4 and Figure 5 As shown, the mounting plate 403 and the shear box 2 are elastically connected via elastic members 3 9 , and each group of two elastic members 3 9 is located at the top of the mounting plate 403 . A square groove is provided on the surface of the square shell 401 , and the push rod 406 can move inside the square groove.

[0055] The above solution is adopted: through the design of elastic member three 9, when the push rod 406 pushes the mounting plate 403 to descend, the elastic member three 9 will be stretched, and then when the mounting plate 403 is reset, the stretched elastic member three 9 will assist the motor 407 to pull the mounting plate 403 to reset, thereby reducing the load of the motor 407. Through the design of the square shell 401, since a square groove is provided on the surface of the square shell 401, when the push rod 406 rotates, the square shell 401 will not interfere with the rotation of the push rod 406, and the surface of the push rod 406 fits with the inner wall of the square groove, and can limit the push rod 406 during its rotation.

[0056] like Figure 6 As shown, the sealing plate 502 is square in design, and the surface of the sealing plate 502 fits the inner wall of the main body 1 ; the bottom end of the extrusion rod 504 is chamfered in design, and the surface of the extrusion rod 504 fits the inner wall of the main body 1 .

[0057] The above solution is adopted: through the design of the sealing plate 502, since the surface of the sealing plate 502 fits against the inner wall of the main body 1, gas loss is avoided, ensuring that the flowing air pushes the rack 501 and the sealing plate 502 to move, and through the design of the extrusion rod 504, since the bottom end of the extrusion rod 504 is chamfered, it is convenient for the extrusion rod 504 to enter the inner wall of the main body 1, and the surface of the extrusion rod 504 fits against the inner wall of the main body 1, so that it can push the air inside the main body 1 to move normally.

[0058] The working principle and use process of the present invention:

[0059] The operator unrolls the rolled steel plate and places the unrolled end on the top of the main body 1. The conveyor roller on the top of the main body 1 drives the steel plate to move into the shear box 2. Then, the two motors 407 are driven to rotate the two gears 1 405. The two gears 1 405 drive the push rod 406 to rotate, and push the sliding rod 402, the mounting plate 403 and the extrusion wheel 404 to descend.

[0060] During the descent process, the extrusion rod 504 will enter the interior of the main body 1 in advance and promote the flow of gas inside the main body 1, and the flowing gas will push the sealing plate 502 and the rack 501 to move. When the sealing plate 502 moves, the elastic member 1 503 will be stretched, and then the moving rack 501 will drive the gear 2 601 and the screw rod 602 to rotate, and the threaded plate 603 will move on the surface of the screw rod 602. The threaded plate 603 will drive the square plate 604, the elastic member 2 605 and the positioning plate 606 to move toward the surface of the steel plate, and the positioning plate 606 will contact the surface of the steel plate and push the steel plate to move. When the four positioning plates 606 contact the steel plate at the same time, the steel plate can be positioned in the middle of the top of the main body 1;

[0061] Then, the extrusion wheel 404 will contact the moving steel plate to squeeze the steel plate to level the bent steel plate, and the moving steel plate will drive the extrusion wheel 404 to rotate, so as not to interfere with the movement of the steel plate. When the steel plate moves to the position where shearing is required, the cylinder 702 is driven so that its output shaft pushes the fixed plate 703 down, and then the bottom end of the fixed plate 703 contacts the surface of the steel plate, thereby fixing the steel plate. Finally, the electric push rod 301 is driven to make the shear blade 302 shear the steel plate, and finally the operation process is completed.
