Description

Technical Field

[0001] This utility model relates to the field of strip steel shearing technology, and more specifically, to a strip steel shearing device. Background Technology

[0002] Steel strips are widely used in the construction industry to strengthen concrete components, increasing their load-bearing capacity and stability. They are also used to manufacture components for buildings such as bridges and tunnels, ensuring the safety and stability of the building structure. For example, in the steel structures of high-rise buildings, using high-strength steel strips can reduce the amount of material used while ensuring the stability and safety of the structure.

[0003] However, when shearing strip steel, due to the varying widths of the strip steel, in traditional equipment, the strip steel with the smaller width is placed under the rotating roller for cutting. Since the frictional force between the strip steel surface and the rotating roller surface is not uniform everywhere, the strip steel sometimes shifts to one side due to friction during shearing, resulting in a non-rectangular strip steel. This shearing process can produce some defective products, so it is necessary to improve and optimize the strip steel shearing structure. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a strip shearing device, which has the advantages of stably obtaining rectangular strips and preventing the strips from being cut crooked during shearing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a strip shearing device, including a shearing table, a first bracket fixedly connected to the upper right surface of the shearing table, a first motor fixedly mounted on the upper rear surface of the first bracket, a bidirectional threaded rod fixedly connected to the output shaft of the first motor, the bidirectional threaded rod being rotatably connected inside the first bracket, a slider threadedly connected to both the front and rear curved surfaces of the bidirectional threaded rod, a limit plate fixedly connected to the lower surface of the slider, a first sliding groove opened in the upper part of the first bracket, the slider being movably connected inside the first sliding groove, a limit post fixedly connected to the lower inner side of the first bracket, and the limit plate being movably connected to the outer surface of the limit post.

[0006] As a preferred technical solution of this utility model: a spring is fixedly connected to the upper surface of the shearing table, a sliding column is fixedly connected to the upper surface of the shearing table, the sliding column is located inside the spring, a pressure plate is fixedly connected to the upper surface of the spring, a first cutting groove is formed in the middle of the pressure plate, and a second cutting groove is formed in the middle upper surface of the shearing table, the first cutting groove and the second cutting groove have the same shape.

[0007] As a preferred technical solution of this utility model: a support plate is fixedly connected to the front surface of the shearing table, a second motor is fixedly installed on the upper surface of the support plate, a first helical gear is fixedly installed on the output shaft of the second motor, a threaded rod is rotatably connected to the upper surface of the support plate, a second helical gear is fixedly connected to the lower part of the threaded rod, the second helical gear and the first helical gear mesh with each other, and a cutting structure is threadedly connected to the upper end of the threaded rod.

[0008] As a preferred technical solution of this utility model: a second bracket is fixedly connected to the upper surface of the shearing table, an electric rotary roller is fixedly installed on the inner side of the second bracket, and a second sliding groove is provided on one side of the second bracket.

[0009] As a preferred technical solution of this utility model: the cutting structure includes a mounting plate movably connected inside the second slide groove, a cutting blade assembly is fixedly installed in the middle of the mounting plate, and an internal thread fixing block is fixedly connected to the front end of the mounting plate, the internal thread fixing block being threadedly connected to a threaded rod.

[0010] As a preferred technical solution of this utility model: a driving block is fixedly connected to the lower surface of the mounting plate, and the height of the driving block is greater than the height of the cutter assembly.

[0011] As a preferred technical solution of this utility model: a controller is fixedly connected to the upper surface of the shearing table, a strip steel coil is fixedly connected to the right end of the shearing table, a collection box is placed on the upper left surface of the shearing table, a material receiving assembly is fixedly installed on the upper left surface of the shearing table, and a sensor is fixedly connected to the upper surface of the shearing table.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses the operation of a first motor to drive the rotation of a bidirectional threaded rod, which in turn drives the relative movement of a slider threaded to the surface of the bidirectional threaded rod. This satisfies the relative movement of the limiting plate, so that the inner wall of the limiting plate can limit the shearing of the strip steel, thereby ensuring that the cutting surface of the strip steel is perpendicular to the side of the strip steel, thus meeting people's needs. Compared with traditional devices, there will be a certain error in the shearing of the strip steel, resulting in the strip steel being cut into an irregular quadrilateral instead of a rectangle. This device improves the quality of strip steel shearing.

[0014] 2. This utility model applies downward pressure to the pressure plate during strip shearing, thereby firmly pressing the strip between the upper surface of the shearing table and the lower surface of the pressure plate. The combined use of springs and sliding columns can prevent deformation of the springs due to prolonged use, and can simultaneously ensure that the strip is pressed and does not conflict with the transmission during the shearing cycle. Compared with traditional devices, the cut will deform due to the pressure of the blade during shearing. This device greatly reduces the deformation of the cut, making the cut smoother and thus obtaining high-quality strip blocks. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a strip shearing device, including a shearing table 1. A first bracket 2 is fixedly connected to the upper right end of the shearing table 1. A first motor 3 is fixedly installed on the upper rear end of the first bracket 2. A bidirectional threaded rod 4 is fixedly connected to the output shaft of the first motor 3. The bidirectional threaded rod 4 is rotatably connected inside the first bracket 2. A slider 5 is threadedly connected to the curved surfaces of the front and rear parts of the bidirectional threaded rod 4. A limit plate 6 is fixedly connected to the lower surface of the slider 5. A first groove 7 is opened in the upper part of the first bracket 2. The slider 5 is movably connected inside the first groove 7. A limit post 8 is fixedly connected to the inner side of the lower part of the first bracket 2. The limit plate 6 is movably connected to the outer surface of the limit post 8.

[0023] When the worker puts the steel strip to be cut into the steel strip coil 26 and starts the first motor 3, the rotation of the output shaft of the first motor 3 drives the bidirectional threaded rod 4 to rotate. At the same time, the threads on the surface of the bidirectional threaded rod 4 are opposite, so the slider 5 connected by the threads on the surface of the bidirectional threaded rod 4 will move relative to each other, thereby driving the limiting plate 6 to move relative to each other. The limiting post 8 is fixedly connected to the inner side of the front and rear ends of the first bracket 2, so that the limiting plate 6 can move horizontally smoothly, thereby clamping steel strips of different widths. Due to the design of the first slide groove 7 and the limiting post 8, the slider 5 can be limited to move.

[0024] Among them, a spring 20 is fixedly connected to the upper surface of the shearing table 1, a sliding column 21 is fixedly connected to the upper surface of the shearing table 1, the sliding column 21 is located inside the spring 20, a pressure plate 22 is fixedly connected to the upper surface of the spring 20, a first cutting groove 23 is opened in the middle of the pressure plate 22, and a second cutting groove 24 is opened in the middle upper surface of the shearing table 1. The first cutting groove 23 and the second cutting groove 24 have the same shape.

[0025] When the strip passes through the inner side of the limiting plate 6, it is then driven by the electric roller 15 until one end of the strip reaches the receiving assembly 28. The controller 25 stops the transmission and the second motor 10 starts, thereby driving the cutting structure to descend. When the drive block 30 contacts the upper surface of the pressure plate 22, it will exert downward pressure on the pressure plate 22. Due to the elastic potential energy of the spring 20 and the limiting of the sliding column 21, the pressure plate 22 descends until the pressure plate 22 and the shearing table 1 clamp the strip. At this time, the cutter assembly 18 is exactly inside the second cutting groove 24, thereby shearing the strip. When the shearing is completed, the cutting structure rises and returns to its original position, thus starting the next cycle.

[0026] The front surface of the shearing table 1 is fixedly connected to a support plate 9. The upper surface of the support plate 9 is fixedly installed with a second motor 10. The output shaft of the second motor 10 is fixedly installed with a first helical gear 11. The upper surface of the support plate 9 is rotatably connected with a threaded rod 12. The lower part of the threaded rod 12 is fixedly connected with a second helical gear 13. The second helical gear 13 and the first helical gear 11 mesh with each other. The upper end of the threaded rod 12 is threadedly connected with a cutting structure.

[0027] The support plate 9 provides an upward force to the second motor 10. The rotation of the output shaft of the second motor 10 drives the first helical gear 11 to rotate, which in turn drives the second helical gear 13, which meshes with the first helical gear 11, to rotate. This, in turn, drives the threaded rod 12 to rotate on the upper surface of the support plate 9. At this time, the internal threaded fixing block 19, which is threadedly connected to the threaded rod 12, moves downward, thereby driving the cutting mechanism to cut downward.

[0028] The upper surface of the shearing table 1 is fixedly connected to a second bracket 14, an electric rotary roller 15 is fixedly installed on the inner side of the second bracket 14, and a second slide groove 16 is provided on one side of the second bracket 14.

[0029] The second slide 16 limits the movement of the mounting plate 17 up and down along the inside of the second slide 16, and the electric roller 15 allows the strip steel to be transferred at the shearing position.

[0030] The cutting structure includes a mounting plate 17 movably connected inside the second slide groove 16. A cutter assembly 18 is fixedly mounted in the middle of the mounting plate 17, and an internal threaded fixing block 19 is fixedly connected to the front end of the mounting plate 17. The internal threaded fixing block 19 is threadedly connected to the threaded rod 12.

[0031] The cutter assembly 18 is fixedly installed inside the mounting plate 17, allowing for quick replacement of the cutter assembly 18. The internal threaded fixing block 19 is fixedly connected to the side of the mounting plate 17, thereby enabling the mounting plate 17 to move up and down.

[0032] The lower surface of the mounting plate 17 is fixedly connected to a drive block 30, and the height of the drive block 30 is greater than the height of the cutter assembly 18.

[0033] By designing the drive block 30, when the mounting plate 17 descends, the drive block 30 will first contact the upper surface of the pressure plate 22 to prevent the strip from not being clamped when the cutter assembly 18 is shearing.

[0034] The upper surface of the shearing table 1 is fixedly connected to a controller 25, the right end of the shearing table 1 is fixedly connected to a strip steel coil 26, the upper left surface of the shearing table 1 is placed with a collection box 27, the upper left surface of the shearing table 1 is fixedly installed with a material receiving assembly 28, and the upper surface of the shearing table 1 is fixedly connected to a sensor 29.

[0035] The controller 25 controls the transmission and operation of each motor, the strip coil 26 provides raw materials for shearing, the receiving assembly 28 transports the sheared strip to the next step, the sensor 29 realizes fixed-point length shearing, and the collection box 27 facilitates the collection of the sheared finished products.

[0036] Working principle and usage process of this utility model:

[0037] When the worker puts the steel strip to be cut into the steel strip coil 26 and starts the first motor 3, the rotation of the output shaft of the first motor 3 drives the bidirectional threaded rod 4 to rotate. At the same time, the threads on the surface of the bidirectional threaded rod 4 are opposite, so the slider 5 connected by the threads on the surface of the bidirectional threaded rod 4 will move relative to each other, thereby driving the limiting plate 6 to move relative to each other. The limiting post 8 is fixedly connected to the inner side of the front and rear ends of the first bracket 2, so that the limiting plate 6 can move horizontally smoothly, thereby clamping steel strips of different widths. Due to the design of the first slide groove 7 and the limiting post 8, the slider 5 can be limited to move.

[0038] When the strip passes through the inner side of the limiting plate 6, it is then driven by the electric roller 15 until one end of the strip reaches the receiving assembly 28. The controller 25 stops the transmission and the second motor 10 starts, thereby driving the cutting structure to descend. When the drive block 30 contacts the upper surface of the pressure plate 22, it will exert downward pressure on the pressure plate 22. Due to the elastic potential energy of the spring 20 and the limiting of the sliding column 21, the pressure plate 22 descends until the pressure plate 22 and the shearing table 1 clamp the strip. At this time, the cutter assembly 18 is exactly inside the second cutting groove 24, thereby shearing the strip. When the shearing is completed, the cutting structure rises and returns to its original position, thus starting the next cycle.

[0039] The support plate 9 provides an upward force to the second motor 10. The rotation of the output shaft of the second motor 10 drives the first helical gear 11 to rotate, which in turn drives the second helical gear 13, which meshes with the first helical gear 11, to rotate. This, in turn, drives the threaded rod 12 to rotate on the upper surface of the support plate 9. At this time, the internal threaded fixing block 19, which is threadedly connected to the threaded rod 12, moves downward, thereby driving the cutting mechanism to cut downward.

[0040] The second slide 16 limits the movement of the mounting plate 17 up and down along the inside of the second slide 16, and the electric roller 15 allows the strip steel to be transferred at the shearing position.

[0041] The cutter assembly 18 is fixedly installed inside the mounting plate 17, allowing for quick replacement of the cutter assembly 18. The internal threaded fixing block 19 is fixedly connected to the side of the mounting plate 17, thereby enabling the mounting plate 17 to move up and down.

[0042] By designing the drive block 30, when the mounting plate 17 descends, the drive block 30 will first contact the upper surface of the pressure plate 22 to prevent the strip from not being clamped when the cutter assembly 18 is shearing.

[0043] The controller 25 controls the transmission and operation of each motor, the strip coil 26 provides raw materials for shearing, the receiving assembly 28 transports the sheared strip to the next step, the sensor 29 realizes fixed-point length shearing, and the collection box 27 facilitates the collection of the sheared finished products.
