Description

Technical Field

[0001] The invention belongs to the technical field of steel coil shearing, in particular to a steel coil shearing device. Background Art

[0002] In the field of steel coil processing, steel coil shears are key equipment used to cut steel coils into steel sheets of required size.

[0003] When the existing steel coil shearing machine is in use, first, the steel coil is placed on the coil feeding device, and the coil feeding roller is driven to rotate by the motor. Relying on the friction between the coil feeding roller and the steel coil, the steel coil is smoothly and continuously fed into the subsequent processing area and enters the shearing stage. When the steel coil reaches the designated position, the hydraulic system or mechanical transmission system of the shearing machine starts working, driving the shearing tool to press down quickly. With the powerful shearing force of the tool, the steel coil is accurately cut according to the preset size requirements to ensure that the shearing surface is flat and burr-free. After the shearing is completed, the sheared plate is smoothly moved out of the shearing position by the conveyor belt and sent to the designated area for stacking or further processing.

[0004] However, when the existing steel coil shearing machine is in use, the end of the steel coil being cut will warp up. This is caused by the shear blade being quickly pressed down by the hydraulic system to cut. When the shear blade contacts the steel coil, a huge shear force is concentrated on the part of the steel coil to be cut. Since the steel coil has a certain flexibility and elasticity, stress concentration will occur in the force-bearing area of the steel coil during the downward pressure of the shear blade. Under the strong pressure of the shear blade's rapid downward pressure, the part of the steel coil close to the shear edge will be subjected to a downward shear force, while the adjacent unsheared part, since it has not yet been directly sheared, still maintains its original state and stress distribution. This uneven force situation causes a stress difference to be formed near the sheared end of the steel coil. When the shear blade continues to press down until the shearing is completed, the part of the steel coil close to the shear edge and that has been separated from the main body of the steel coil will warp up due to the loss of the constraint of the surrounding steel coils, resulting in the phenomenon of warping of the sheared end. This not only affects the shearing quality, but also may bring inconvenience to subsequent processing and operation.

[0005] To this end, the present invention provides a steel coil shearing device. Summary of the Invention

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1: Figures 1 to 8 As shown, a steel coil shearing device according to an embodiment of the present invention includes a body 1, a conveyor belt 11 is connected to the surface of the body 1, a first hydraulic cylinder 12 is provided at one end of the body 1, a guillotine 13 is fixedly connected to the output end of the first hydraulic cylinder 12, a steel frame 2 is provided on one side of the body 1, an adjustment component is provided on the upper surface of the body 1, and the adjustment component includes two support plates 4 fixedly connected to the upper surface of the body 1, a sliding groove 41 is provided on the surface of the support plate 4, a rotating shaft 46 is slidably connected in the sliding groove 41, and the circular axis of the rotating shaft 46 is provided. An extrusion roller 47 is fixedly connected to the circumferential surface; an auxiliary component is provided on the upper surface of each support frame, and the auxiliary component includes a connecting groove 410 opened on the upper surface of the support frame, a first guide plate 411 is slidably connected in the connecting groove 410, a first guide groove 412 is opened on one side of the first guide plate 411, a first guide block 413 is slidably connected in the first guide groove 412, and the bottom end of the first guide block 413 is rotatably connected to an auxiliary roller 415; a clamping component is provided at one end of the machine body 1 close to the steel frame 2, and the clamping component is used to temporarily fix the roll 3.

[0025] Specifically, when the existing steel coil shearing machine is in use, the end of the steel coil being cut will warp. This is caused by the shear blade being driven by the hydraulic system to quickly press down to cut. When the shear blade contacts the steel coil, a huge shear force is concentrated on the part of the steel coil to be cut. Since the steel coil has a certain degree of flexibility and elasticity, stress concentration will occur in the force-bearing area of the steel coil during the downward pressure of the shear blade. Under the strong pressure of the shear blade's rapid downward pressure, the part of the steel coil close to the cutting edge will be subjected to a downward shear force, while the adjacent uncut part, since it has not yet been directly sheared, still maintains its original state and stress distribution. This uneven force situation causes a stress difference to form near the cut end of the steel coil. When the shear blade continues to press down until the shearing is completed, the part of the steel coil close to the cutting edge and that has been separated from the main body of the steel coil will warp upward due to the loss of the constraint of the surrounding steel coils, resulting in the shear end warping phenomenon. This not only affects the shearing quality, but also may cause inconvenience to subsequent processing and operation. Therefore, the present invention sets the above structure to solve the above problem. First, when the steel coil shearing equipment is working, the steel coil is placed on the steel frame 2, and the steel coil is conveyed to the machine body 1. After conveying a certain length, the first hydraulic cylinder 12 is started to drive the shearing knife 13 to cut the coil 3 of the steel coil. After the shearing is completed, the sheared end is clamped by starting the clamping component. At this time, the tilted end of the steel coil is adjusted by the adjustment component. First, the driving shaft 46 slides in the sliding groove 41 of the support plate 4, and the sliding trajectory is arc-shaped, which drives the squeezing roller 47 to convey the steel coil. The steel coil being fed is squeezed and leveled to ensure that it is flat before entering the subsequent process. During the adjustment process, the first guide plate 411 of the auxiliary component slides in the connecting groove 410, and the first guide block 413 moves in the first guide groove 412 to adjust the position of the auxiliary roller 415. The auxiliary roller 415 contacts the steel coil to further guide and stabilize the adjustment of the steel coil. This is similar to the curled paper. The paper is clamped by hand and then straightened. The auxiliary roller 415 and the squeezing roller 47 simulate manual operation to straighten the coil 3 after cutting, thereby improving the efficiency of the coil 3 in subsequent processing. The adjustment components and auxiliary components work together to effectively adjust the flatness of the steel coil after cutting, prevent it from curling, and improve the shearing quality. The clamping component temporarily fixes the coil 3 to avoid the displacement of the steel coil due to external force during the adjustment process, ensuring stable adjustment. The various components cooperate with each other and have a high degree of automation, which can greatly improve the efficiency of steel coil shearing, reduce manual labor intensity, and at the same time ensure stable product quality. It is suitable for large-scale steel coil shearing production and has high practicality and economic value.

[0026] like Figure 3As shown, in this embodiment, a motor 44 is fixedly connected to the surface of the body 1, and the output end of the motor 44 is fixedly connected to a telescopic plate 43. Two auxiliary plates 42 are provided at the ends of the body 1 corresponding to the telescopic plate 43. The output end of the motor 44 passes through the auxiliary plate 42, and the telescopic plate 43 is rotatably connected between the two auxiliary plates 42. One end of the telescopic plate 43 is fixedly connected to a connecting block 45, and the connecting block 45 is rotatably connected to the rotating shaft 46.

[0027] Specifically, when the web 3 extends to a certain size, it is cut by the guillotine 13, and the cut end is temporarily fixed by the clamping assembly. At this time, the motor 44 is started to drive the telescopic plate 43 to rotate under the limit of the auxiliary plate 42. The rotation of the telescopic plate 43 drives the rotating shaft 46 to drive the squeezing roller 47 to rotate along the sliding groove 41, and the auxiliary assembly will initially start the first guide groove 412 in the first guide plate 411, drive the first guide block 413 to descend, so that the auxiliary roller 415 and the squeezing roller 47 clamp the web 3. The auxiliary roller 415 moves laterally with the squeezing roller 47 under the drive of the connecting groove 410, and the first guide groove 412 controls its longitudinal movement, cooperating with the squeezing roller 47 to always clamp the web 3, wherein the connecting groove 410 is an electric slide rail; When adjusting the roll 3, the clamping assembly temporarily fixes the roll 3 to ensure stable adjustment. After starting the motor 44, the telescopic plate 43 drives the squeezing roller 47 to rotate and move along the sliding groove 41. At the same time, the auxiliary assembly drives the auxiliary roller 415 to descend and cooperate with the squeezing roller 47 to clamp the roll 3. The auxiliary roller 415 moves flexibly horizontally and vertically with the squeezing roller 47, and can always maintain effective clamping of the roll 3 to prevent the roll 3 from shifting or shaking during the adjustment process, effectively improving the adjustment accuracy and product quality, and ensuring the stability of production.

[0028] like Figure 5 and Figure 7 As shown, the clamping assembly of this embodiment includes a base plate 420 fixed to the surface of the body 1, an electric push rod 431 is provided on the upper surface of the base plate 420, the output end of the electric push rod 431 is fixed to the positioning plate 419, and a fixed plate 417 is fixed between the two support plates 4. The electric push rod 431 drives the positioning plate 419 to move upward, and the fixed plate 417 is fixed to stationary, thereby clamping the end of the roll 3 after cutting.

[0029] Specifically, during the steel coil adjustment process, when the coil 3 is extended to the appropriate size for cutting, the clamping assembly starts to work, and the electric push rod 431 located on the bottom plate 420 on the surface of the body 1 is started, and its output end pushes the positioning plate 419 upward. At the same time, the fixed plate 417 fixed between the two support plates 4 remains stationary. As the electric push rod 431 continuously drives the positioning plate 419 to rise, the positioning plate 419 gradually approaches the fixed plate 417, and finally the two form a clamp on the end of the cut coil 3, firmly fixing it between the two to prevent the coil 3 from moving in subsequent operations. By driving the positioning plate 419 to move by the electric push rod 431, the end of the coil 3 can be clamped quickly and accurately, and the operation is convenient. The fixed plate 417 cooperates with the positioning plate 419 to ensure that the coil 3 remains stable during the clamping process, avoiding the shaking of the coil 3 affecting the shearing accuracy and subsequent processing quality, thereby improving production efficiency and product qualification rate.

[0030] like Figure 7 As shown, in this embodiment, a guide arc plate 418 is fixedly connected to one side of the fixed plate 417, and the guide arc plate 418 guides the roll film 3 to pass between the positioning plate 419 and the fixed plate 417. A concave arc plate 429 is fixedly connected to one side of the positioning plate 419, and the inner wall of the concave arc plate 429 is rotatably connected to a connecting column 430, which is used to adhere to the dust on the surface of the roll film 3.

[0031] Specifically, when the end of the cut film 3 enters the clamping area, the guide arc plate 418 on the side of the fixed plate 417 plays a guiding role. Its arc design can naturally guide the film 3 to pass through the space between the positioning plate 419 and the fixed plate 417, ensuring that the film 3 reaches the clamping position accurately. The concave arc plate 429 on one side of the positioning plate 419 contacts the surface of the film 3. The connecting column 430 rotatably connected to the inner wall of the concave arc plate 429 rotates due to friction during the movement of the film 3, and uses its own characteristics to adhere to the dust on the surface of the film 3. As the film 3 continues to move, the connecting column 430 continues to rotate and continuously cleans the dust to ensure the cleanliness of the surface of the film 3. The design of the guide arc plate 418 enables the film 3 to enter the clamping position quickly and accurately, improves the clamping efficiency, and reduces problems caused by position deviation. The connecting column 430 can actively adhere to the dust on the surface of the film 3 to avoid dust affecting the subsequent processing quality, ensure product quality, effectively improve the degree of automation of the clamping and cleaning of the film 3, reduce the cost of manual cleaning, and ensure the smooth progress of production.

[0032] Example 2: Figures 1 to 8As shown, comparative example 1, another embodiment of the present invention is: a storage box 5 is provided on one side of the body 1, and the storage box 5 stores anti-corrosion coating liquid, and the storage box 5 is rotatably connected to the rotating shaft 46 through a connecting pipe 51 fixed to its upper surface, and two adhesive blocks 422 are fixed on the circumferential surface of the extrusion roller 47, and the adhesive blocks 422 are used to adhere the anti-corrosion coating liquid to the surface of the roll 3, a rack plate 49 is fixed on one side of the support plate 4, and a gear 48 is fixed on the circumferential surface of the rotating shaft 46, and an auxiliary plate 42 is provided on one side of the body 1, and a telescopic tube 421 is rotatably connected between the two auxiliary plates 42, and the telescopic tube 421 is fixed to the connecting pipe 51.

[0033] Specifically, when the squeezing roller 47 rotates to the middle of the support frame along with the telescopic plate 43, the cone plate 424 on one side of the squeezing roller 47 contacts the protrusion 423, and the protrusion 423 squeezes the cone plate 424 into the squeezing roller 47. At this time, the positioning hole 427 on the surface of the cone plate 424 is aligned with the fixing hole 425 on the circumferential surface of the fixed shaft. At this time, the anti-corrosion coating liquid in the storage box 5 is pressurized and passes into the telescopic tube 421 from the connecting pipe 51, and then passes into the fixing hole 425 from the telescopic tube 421, and then flows into the positioning hole 427 to infiltrate the adhesive block 422. Then, the motor 44 drives the telescopic plate 43 to rotate. During the rotation process, the gear 48 fixed to the circumferential surface of the rotating shaft 46 will rotate along the rack plate 49, thereby driving the squeezing roller 47 to slide in an arc while rotating, thereby coating the surface of the roll film 3. When the squeezing roller 47 moves to the middle of the support plate 4, the protrusion 423 squeezes the cone plate 424 to align the positioning hole 427 with the fixing hole 425, and the anti-corrosion coating flows smoothly into the infiltration adhesion block 422 to prepare for subsequent coating. When the motor 44 drives the telescopic plate 43 to rotate, the gear 48 cooperates with the rack plate 49 to make the squeezing roller 47 slide in an arc while rotating, which can evenly and comprehensively coat the surface of the roll sheet 3, improve the coating quality, effectively prevent the roll sheet 3 from corrosion, extend the service life of the roll sheet 3, and at the same time ensure the performance and stability of the subsequent processing and use of the roll sheet 3.

[0034] like Figure 6 As shown, the auxiliary equipment of this embodiment also includes a connecting box 414 fixedly connected to one side of the first guide block 413, and the lower surface of the connecting box 414 is rotatably connected to a coating roller 416. The connecting box 414 stores anti-corrosion coating liquid, and the coating roller 416 transfers the anti-corrosion coating liquid to the circumferential surface of the auxiliary roller 415, which is then coated on the surface of the roll 3 through the auxiliary roller 415.

[0035] Specifically, during the adjustment process of the auxiliary roller 415 assisting the squeezing roller 47, the connecting box 414 is fixed to one side of the first guide block 413, and the anti-corrosion coating liquid is stored inside it. When the equipment processes the roll sheet 3, the smearing roller 416 connected to the lower surface of the connecting box 414 starts to work, and the smearing roller 416 contacts the anti-corrosion coating liquid in the connecting box 414. During the rotation process, the coating liquid is absorbed and transferred to the circumferential surface of the auxiliary roller 415. As the auxiliary roller 415 contacts the surface of the roll sheet 3, the anti-corrosion coating liquid is evenly applied to the surface of the roll sheet 3 through the auxiliary roller 415, thereby completing the anti-corrosion coating of the roll sheet 3. By utilizing the cooperation of the coating roller 416 and the auxiliary roller 415, the anti-corrosion coating can be efficiently and evenly applied to the surface of the roll sheet 3, thereby improving the anti-corrosion performance of the roll sheet 3 and extending the service life of the roll sheet 3. At the same time, the structure is simple and easy to operate, and can be well connected with the overall process of the equipment. Without affecting the normal progress of other processes, the anti-corrosion coating can be applied, thereby improving production efficiency and product quality.

[0036] Working principle: First, when the steel coil shearing equipment is working, the steel coil is placed on the steel rack 2, and the steel coil is conveyed to the machine body 1. After conveying a certain length, the first hydraulic cylinder 12 is started to drive the shearing knife 13 to shear the coil 3 of the steel coil. After the shearing is completed, the clamping component starts to work, and the electric push rod 431 located on the bottom plate 420 on the surface of the machine body 1 is started, and its output end pushes the positioning plate 419 upward. At the same time, the fixed plate 417 fixed between the two support plates 4 remains fixed. As the electric push rod 431 continuously drives the positioning plate 419 to rise, the positioning plate 419 gradually approaches the fixed plate 41 7. Finally, the two clamp the end of the cut film 3 and firmly fix it between them to prevent the film 3 from moving during subsequent operations. The auxiliary component will initially activate the first guide groove 412 in the first guide plate 411, drive the first guide block 413 to descend, so that the auxiliary roller 415 and the squeezing roller 47 clamp the film 3. In the subsequent adjustment work, the auxiliary roller 415 moves laterally with the squeezing roller 47 under the drive of the connecting groove 410, and at the same time, the first guide groove 412 controls its longitudinal movement, cooperating with the squeezing roller 47 to always clamp the film 3. The connecting groove 410 is an electric slide rail. Then, the adjustment component is used to adjust the raised end of the steel coil. First, the driving shaft 46 slides in the sliding groove 41 of the support plate 4, and the sliding track is arc-shaped, thereby driving the squeezing roller 47 to squeeze and level the steel coil being transported to ensure that the steel coil enters the subsequent process flatly. During the adjustment process, the first guide plate 411 of the auxiliary component slides in the connecting groove 410, and the first guide block 413 moves in the first guide groove 412 to adjust the position of the auxiliary roller 415. The auxiliary roller 415 contacts the steel coil to further guide and stabilize the adjustment of the steel coil. This is similar to the curled paper. The paper is clamped by hand and then straightened. The auxiliary roller 415 and the squeezing roller 47 simulate manual operation to straighten the coil 3 after cutting, thereby improving the subsequent processing efficiency of the coil 3. The adjustment component and the auxiliary component work together to effectively adjust the flatness of the steel coil after cutting, prevent it from curling, and improve the shearing quality. The clamping component temporarily fixes the coil 3 to avoid displacement of the steel coil due to external forces during the adjustment process, ensuring stable adjustment. The various components cooperate with each other, with a high degree of automation, which can greatly improve the efficiency of steel coil shearing, reduce manual labor intensity, and ensure stable product quality. It is suitable for large-scale steel coil shearing production and has high practicality and economic value. When the squeezing roller 47 rotates to the middle of the support frame along with the telescopic plate 43, the cone plate 424 on one side of the squeezing roller 47 contacts the protrusion 423, and the protrusion 423 squeezes the cone plate 424 into the squeezing roller 47. At this time, the positioning hole 427 on the surface of the cone plate 424 is aligned with the fixing hole 425 on the circumferential surface of the fixed shaft. At this time, the anti-corrosion coating liquid in the storage box 5 is pressurized and passes into the telescopic tube 421 from the connecting pipe 51, and then passes into the fixing hole 425 from the telescopic tube 421, and then flows into the positioning hole 427 to infiltrate the adhesive block 422. Then, the motor 44 drives the telescopic plate 43 to rotate. During the rotation process, the gear 48 fixed to the circumferential surface of the rotating shaft 46 will rotate along the rack plate 49, thereby driving the squeezing roller 47 to slide in an arc while rotating, thereby coating the surface of the roll film 3. When the squeezing roller 47 moves to the middle of the support plate 4, the protrusion 423 squeezes the cone plate 424 to align the positioning hole 427 with the fixing hole 425, and the anti-corrosion coating flows smoothly into the infiltration adhesion block 422 to prepare for subsequent coating. When the motor 44 drives the telescopic plate 43 to rotate, the gear 48 cooperates with the rack plate 49 to make the squeezing roller 47 slide in an arc while rotating, which can evenly and comprehensively coat the surface of the roll sheet 3, improve the coating quality, effectively prevent the roll sheet 3 from corrosion, extend the service life of the roll sheet 3, and at the same time ensure the performance and stability of the subsequent processing and use of the roll sheet 3.
