Description

Technical Field

[0001] This invention belongs to the field of steel coil shearing technology, specifically a steel coil shearing device. Background Technology

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

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

[0004] However, in existing steel coil shearing machines, the ends of the steel coils being cut tend to curl up. This is caused by the shearing blade rapidly pressing down under the hydraulic system for shearing. The moment the shearing blade contacts the steel coil, a huge shearing force is concentrated on the part of the coil to be cut. Due to the steel coil's flexibility and elasticity, stress concentration occurs in the stressed area during the downward pressure of the shearing blade. Under the strong pressure of the rapidly pressing shearing blade, the part of the steel coil near the shearing edge experiences a downward shearing force, while the adjacent uncut part, not yet subjected to direct shearing, maintains its original state and stress distribution. This uneven stress distribution creates a stress difference near the shearing end of the steel coil. When the shearing blade continues to press down until the shearing is complete, the part of the steel coil near the shearing edge, which has detached from the main body of the coil, will curl up due to the loss of constraint from the surrounding steel coil, resulting in the curling of the shearing end. This not only affects the shearing quality but may also cause inconvenience to subsequent processing and operation.

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

[0009] A clamping assembly is provided at one end of the machine body near the steel frame, which is used to temporarily fix the rolled film.

[0010] Preferably, a motor is fixedly connected to one side of the machine body, a telescopic plate is fixedly connected to the output end of the motor, two auxiliary plates are provided at the end of the machine body corresponding to the telescopic plate, the output end of the motor passes through the auxiliary plates, and a telescopic plate is rotatably connected between the two auxiliary plates, a connecting block is fixedly connected to one end of the telescopic plate, and the connecting block is rotatably connected to the rotating shaft.

[0011] Preferably, after the rolled sheet extends to a certain size, it is cut by a guillotine. One end of the cut sheet is temporarily fixed by a clamping assembly. At this time, the motor drives the telescopic plate to rotate under the limit of the auxiliary plate. The rotation of the telescopic plate drives the rotating shaft to rotate the extrusion roller along the sliding groove. Initially, the auxiliary assembly activates the first guide groove in the first guide plate, driving the first guide block to descend, so that the auxiliary roller and the extrusion roller clamp the rolled sheet. The auxiliary roller moves laterally with the extrusion roller under the drive of the connecting groove. At the same time, the first guide groove controls its longitudinal movement, which works with the extrusion roller to clamp the rolled sheet continuously. The connecting groove is an electric slide rail.

[0012] Preferably, the clamping assembly includes a base plate fixed to the surface of the machine body, an electric push rod is provided on the upper surface of the base plate, a positioning plate is fixed to the output end of the electric push rod, and a fixing plate is fixed between the two support plates.

[0017] Preferably, when the extrusion roller rotates with the telescopic plate to the middle of the support plate, the conical plate on one side of the extrusion roller contacts the protrusion, and the protrusion squeezes the conical plate into the extrusion roller. At this time, the fixing hole on the surface of the conical plate is aligned with the positioning hole on the circumferential surface of the rotating shaft. At this time, the anti-corrosion coating liquid in the storage box is pressurized and flows into the telescopic pipe through the connecting pipe, then into the fixing hole through the telescopic pipe, and then into the positioning hole to wet the adhesive block. Then the motor drives the telescopic plate to rotate. During the rotation, the gear fixed to the circumferential surface of the rotating shaft will rotate along the rack plate, thereby driving the extrusion roller to rotate while sliding in an arc, thus coating the surface of the roll.

[0018] Preferably, the auxiliary component further includes a connecting box fixed to one side of the first guide block, with an applicator roller rotatably connected to the lower surface of the connecting box.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The steel coil shearing equipment of the present invention adjusts the curled end of the steel coil through an adjustment component. First, the drive rotating shaft slides in the sliding groove of the support plate, and the sliding trajectory is arc-shaped. Then, the extrusion rollers extrude and level the steel coil being conveyed, ensuring that the steel coil is flat before entering the subsequent process. During the adjustment process, the first guide plate of the auxiliary component slides in the connecting groove, and the first guide block moves in the first guide groove to adjust the position of the auxiliary rollers. The auxiliary rollers contact the steel coils, further guiding and stabilizing the steel coil adjustment. This is similar to curled paper, which is straightened by hand. The auxiliary rollers and extrusion rollers simulate human operation to straighten the cut coils, improving the efficiency of the coils in subsequent processing.

[0021] 2. The steel coil shearing equipment of the present invention temporarily fixes the coil during the adjustment process using a clamping component to ensure stable adjustment. After the motor is started, the telescopic plate drives the extrusion roller to rotate and move along the sliding groove. At the same time, the auxiliary component drives the auxiliary roller to descend and cooperate with the extrusion roller to clamp the coil. The auxiliary roller moves flexibly laterally and longitudinally with the extrusion roller, which can always maintain effective clamping of the coil, preventing the coil from shifting or shaking during the adjustment process. This effectively improves the adjustment accuracy and product quality, and ensures the stability of production.

[0022] 3. The steel coil shearing equipment of the present invention, when the extrusion roller moves to the middle of the support plate, the protrusion extrusion cone plate aligns the positioning hole with the fixing hole, and the anti-corrosion coating liquid flows smoothly into the wetting and adhesion block, which replenishes the subsequent coating. When the motor drives the telescopic plate to rotate, the gear and the rack plate cooperate to make the extrusion roller slide in an arc while rotating, which can uniformly and comprehensively coat the surface of the coil, improve the coating quality, effectively prevent the coil corrosion, extend the service life of the coil, and at the same time ensure the performance and stability of the coil in subsequent processing and use.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, a steel coil shearing device includes a body 1, a conveyor belt 11 connected to the surface of the body 1, a first hydraulic cylinder 12 at one end of the body 1, a guillotine 13 fixedly connected to the output end of the first hydraulic cylinder 12, a steel placing frame 2 on one side of the body 1, and an adjustment assembly on the upper surface of the body 1. The adjustment assembly includes two support plates 4 fixedly connected to the upper surface of the body 1. A sliding groove 41 is formed on the surface of the support plates 4, and a rotating shaft 46 is slidably connected in the sliding groove 41. The circumference of the rotating shaft 46 is... The surface is fixed with an extrusion roller 47; each support plate 4 has an auxiliary component on its upper surface, the auxiliary component including a connecting groove 410 opened on the upper surface of the support plate 4, a first guide plate 411 slidably connected in the connecting groove 410, a first guide groove 412 opened on one side of the first guide plate 411, a first guide block 413 slidably connected in the first guide groove 412, and an auxiliary roller 415 rotatably connected to the bottom end of the first guide block 413; a clamping component is provided at one end of the machine body 1 near the steel frame 2, the clamping component is used to temporarily fix the roll 3.

[0035] Specifically, in the use of existing steel coil shearing machines, the end of the steel coil being cut may curl up. This is caused by the shearing blade rapidly pressing down under the drive of the hydraulic system for shearing. When the shearing blade contacts the steel coil, a huge shearing force is concentrated on the part of the steel coil to be cut. Because the steel coil has a certain degree of flexibility and elasticity, stress concentration will occur in the stress area of ​​the steel coil during the downward pressing of the shearing blade. Under the strong pressure of the shearing blade rapidly pressing down, the part of the steel coil near the shearing edge will be subjected to downward shearing force, while the adjacent uncut part, since it has not been directly sheared, will maintain its original state and stress distribution. This uneven stress creates a stress difference near the shearing end of the steel coil. When the shearing blade continues to press down until the shearing is completed, under the combined effect of the sudden release of shearing force and its own elastic recovery, the part of the steel coil near the shearing edge and that has detached from the main body of the steel coil will curl up due to the loss of the constraint of the surrounding steel coil, resulting in the phenomenon of the shearing end curling up. This not only affects the shearing quality but may also cause inconvenience to subsequent processing and operation.

[0036] Therefore, the present invention sets up the above structure to solve the above problems. First, when the steel coil shearing equipment is working, the steel coil is placed on the steel feeding frame 2. The steel coil is conveyed to the machine body 1. After a certain length is conveyed, the first hydraulic cylinder 12 is activated to drive the guillotine 13 to cut the coil 3 that has been fed out of the steel coil. After the cutting is completed, the clamping assembly is activated to clamp the cut end. At this time, the adjustment assembly is used to adjust the raised end of the steel coil. First, the drive rotating shaft 46 slides in the sliding groove 41 of the support plate 4. The sliding trajectory is arc-shaped, which in turn drives the extrusion roller 47 to cut the coil. The steel coil being fed is squeezed and leveled to ensure it is flat before entering the next 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 steel coil adjustment. This is similar to curled paper. The paper is held by hand and then straightened. The auxiliary roller 415 and the squeezing roller 47 simulate human operation to straighten the cut roll 3, which improves the efficiency of the roll 3 in subsequent processing.

[0037] The adjustment and auxiliary components work together to effectively adjust the flatness of the steel coil after shearing, prevent it from curling, and improve the shearing quality. The clamping component temporarily fixes the coil 3, preventing the steel coil from shifting due to external forces during the adjustment process and ensuring stable adjustment. The components cooperate with each other, with a high degree of automation, which can significantly improve the steel coil shearing efficiency, reduce the intensity of manual labor, and ensure stable product quality. It is suitable for large-scale steel coil shearing production and has high practicality and economic value.

[0038] like Figure 3As shown, in this embodiment, a motor 44 is fixedly connected to the surface of the body 1, and a telescopic plate 43 is fixedly connected to the output end of the motor 44. 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. A connecting block 45 is fixedly connected to one end of the telescopic plate 43, and the connecting block 45 is rotatably connected to the rotating shaft 46.

[0039] Specifically, when the roll 3 extends to a certain size, it is cut by the guillotine 13. 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 extrusion roller 47 to rotate along the sliding groove 41. Initially, the auxiliary assembly will activate the first guide groove 412 in the first guide plate 411 to drive the first guide block 413 to descend, so that the auxiliary roller 415 and the extrusion roller 47 clamp the roll 3. The auxiliary roller 415 moves laterally with the extrusion roller 47 under the drive of the connecting groove 410. At the same time, the first guide groove 412 controls its longitudinal movement, which works with the extrusion roller 47 to clamp the roll 3 at all times. The connecting groove 410 is an electric slide rail.

[0040] By temporarily fixing the coil 3 with the clamping assembly during the adjustment of the coil 3, the adjustment is stable. After starting the motor 44, the telescopic plate 43 drives the extrusion 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 extrusion roller 47 to clamp the coil 3. The auxiliary roller 415 moves flexibly laterally and longitudinally with the extrusion roller 47, which can always maintain effective clamping of the coil 3, preventing the coil 3 from shifting or shaking during the adjustment process, effectively improving the adjustment accuracy and product quality, and ensuring the stability of production.

[0041] like Figure 5 and Figure 7 As shown, the clamping assembly in this embodiment includes a base plate 420 fixed to the surface of the machine body 1. An electric push rod 431 is provided on the upper surface of the base plate 420. A positioning plate 419 is fixed to the output end of the electric push rod 431. A fixing plate 417 is fixed between the two support plates 4. The electric push rod 431 drives the positioning plate 419 to move upward, while the fixing plate 417 remains fixed, thus clamping the end of the chopped roll 3.

[0042] Specifically, during the steel coil adjustment process, after the coil 3 extends to the appropriate size for chopping, the clamping assembly begins to work. The electric push rod 431 located on the bottom plate 420 of the machine body 1 is activated, and its output end pushes the positioning plate 419 upward. At the same time, the fixing 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 fixing plate 417. Finally, the two clamp the end of the chopped coil 3, firmly fixing it between them to prevent the coil 3 from moving in subsequent operations. By driving the positioning plate 419 to move through the electric push rod 431, the end of the coil 3 can be clamped quickly and accurately, making the operation convenient. The cooperation between the fixing plate 417 and the positioning plate 419 ensures that the coil 3 remains stable during the clamping process, avoiding the impact of the coil 3 shaking on the cutting accuracy and subsequent processing quality, thus improving production efficiency and product qualification rate.

[0043] like Figure 7 As shown, in this embodiment, a guide arc plate 418 is fixedly connected to one side of the fixing plate 417. The guide arc plate 418 guides the roll 3 to pass between the positioning plate 419 and the fixing plate 417. A concave arc plate 429 is fixedly connected to one side of the positioning plate 419. A connecting post 430 is rotatably connected to the inner wall of the concave arc plate 429. The connecting post 430 is used to adhere dust on the surface of the roll 3.

[0044] Specifically, when the end of the sheared coil 3 enters the clamping area, the guide arc plate 418 on one side of the fixed plate 417 plays a guiding role. Its arc design naturally guides the coil 3 to pass smoothly through the space between the positioning plate 419 and the fixed plate 417, ensuring that the coil 3 accurately reaches the clamping position. The concave arc plate 429 on one side of the positioning plate 419 contacts the surface of the coil 3. The connecting column 430, which is rotatably connected to the inner wall of the concave arc plate 429, rotates due to friction during the movement of the coil 3, and uses its own characteristics to adhere to the dust on the surface of the coil 3. As the coil 3 continues to move, the connecting column 430 continuously rotates and continuously cleans the dust, ensuring the cleanliness of the surface of the coil 3. The design of the guide arc plate 418 enables the coil 3 to quickly and accurately enter the clamping position, improves clamping efficiency, reduces problems caused by positional deviation, and the connecting column 430 can actively adhere to the dust on the surface of the coil 3, preventing dust from affecting the subsequent processing quality, ensuring product quality, effectively improving the automation level of coil 3 clamping and cleaning, reducing manual cleaning costs, and ensuring smooth production.

[0045] Example 2: Figures 1 to 8As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a storage box 5 is provided on one side of the machine body 1, the storage box 5 stores anti-corrosion coating liquid, the storage box 5 is rotatably connected to the rotating shaft 46 through the connecting pipe 51 fixed to its upper surface, two adhesive blocks 422 are fixed to the circumferential surface of the extrusion roller 47, 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 to one side of the support plate 4, a gear 48 is fixed to the circumferential surface of the rotating shaft 46, an auxiliary plate 42 is provided on one side of the machine body 1, a telescopic pipe 421 is rotatably connected between the two auxiliary plates 42, and the telescopic pipe 421 is fixed to the connecting pipe 51.

[0046] Specifically, when the extrusion roller 47 rotates to the middle of the support plate 4 along with the telescopic plate 43, the conical plate 424 on one side of the extrusion roller 47 contacts the protrusion 423, and the protrusion 423 squeezes the conical plate 424 into the extrusion roller 47. At this time, the fixing hole 425 on the surface of the conical plate 424 is aligned with the positioning hole 427 on the circumferential surface of the rotating shaft 46. At this time, the anti-corrosion coating liquid in the storage box 5 is pressurized and passed from the connecting pipe 51 into the telescopic pipe 421, and then from the telescopic pipe 421 into the fixing hole 425, and then flows into the positioning hole 427 to wet the adhesive block 422. Then the motor 44 drives the telescopic plate 43 to rotate. During the rotation, the gear 48 fixed on the circumferential surface of the rotating shaft 46 will rotate along the rack plate 49, thereby driving the extrusion roller 47 to rotate while sliding in an arc, so as to coat the surface of the roll 3.

[0047] When the extrusion roller 47 moves to the middle of the support plate 4, the protrusion 423 extrudes the cone plate 424 to align the positioning hole 427 with the fixing hole 425, allowing the anti-corrosion coating liquid to flow smoothly into the wetting and adhesion block 422, thus preparing for subsequent coating. When the motor 44 drives the telescopic plate 43 to rotate, the gear 48 and the rack plate 49 cooperate to make the extrusion roller 47 slide and rotate in an arc shape, which can uniformly and comprehensively coat the surface of the roll 3, improve the coating quality, effectively prevent the corrosion of the roll 3, extend the service life of the roll 3, and at the same time ensure the performance and stability of the roll 3 in subsequent processing and use.

[0048] like Figure 6 As shown, the auxiliary component in this embodiment also includes a connecting box 414 fixed to one side of the first guide block 413. A coating roller 416 is rotatably connected to the lower surface of the connecting box 414. Anti-corrosion coating liquid is stored in the connecting box 414. The coating roller 416 transfers the anti-corrosion coating liquid to the circumferential surface of the auxiliary roller 415 and applies it to the surface of the roll 3 through the auxiliary roller 415.

[0049] Specifically, during the adjustment of the auxiliary roller 415 and auxiliary extrusion roller 47, the connecting box 414 is fixed to one side of the first guide block 413. It contains an anti-corrosion coating liquid. When the equipment processes the roll 3, the coating roller 416, rotatably connected to the lower surface of the connecting box 414, begins to work. The coating roller 416 contacts the anti-corrosion coating liquid in the connecting box 414, and during rotation, it absorbs and transfers the coating liquid to the circumferential surface of the auxiliary roller 415. As the auxiliary roller 415 contacts the surface of the roll 3, the anti-corrosion coating liquid is evenly applied to the surface of the roll 3 through the auxiliary roller 415, thus completing the application of the anti-corrosion coating liquid to the roll 3.

[0050] By utilizing the cooperation of the coating roller 416 and the auxiliary roller 415, the anti-corrosion coating liquid can be applied to the surface of the roll 3 efficiently and evenly, thereby improving the anti-corrosion performance of the roll 3 and extending its service life. At the same time, the structure is simple and easy to operate, and can be well integrated with the overall process of the equipment. It can achieve the application of anti-corrosion coating liquid without affecting the normal operation of other processes, thus improving production efficiency and product quality.

[0051] Working principle: First, when the steel coil shearing equipment is working, the steel coil is placed on the steel feeding frame 2. The steel coil is conveyed to the machine body 1. After a certain length, the first hydraulic cylinder 12 is activated to drive the guillotine 13 to cut the coil 3 that has been fed out of the machine. After the cutting is completed, the clamping assembly starts to work. The electric push rod 431 located on the bottom plate 420 on the surface of the machine body 1 is activated. 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 41. 7. Finally, the two clamp the end of the cut roll 3, fixing it firmly between them to prevent the roll 3 from moving in subsequent operations. The auxiliary component will activate the first guide groove 412 in the first guide plate 411 at the beginning, driving the first guide block 413 to descend, so that the auxiliary roller 415 and the extrusion roller 47 clamp the roll 3. In subsequent adjustment work, the auxiliary roller 415 moves laterally with the extrusion roller 47 under the drive of the connecting groove 410, while the first guide groove 412 controls its longitudinal movement, cooperating with the extrusion roller 47 to clamp the roll 3 at all times. The connecting groove 410 is an electric slide rail.

[0052] Then, the raised end of the steel coil is adjusted by the adjustment component. First, the drive rotating shaft 46 slides in the sliding groove 41 of the support plate 4, and the sliding trajectory is arc-shaped. Then, the extrusion roller 47 is driven to extrude and level the steel coil in the conveying process, ensuring that the steel coil is flat and enters 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 steel coil adjustment. This is similar to the curled paper. The paper is held by hand and then straightened. The auxiliary roller 415 and the extrusion roller 47 simulate the operation of the hand to straighten the cut roll 3, which improves the efficiency of the roll 3 in subsequent processing.

[0053] The adjustment and auxiliary components work together to effectively adjust the flatness of the steel coil after shearing, prevent it from curling, and improve the shearing quality. The clamping component temporarily fixes the coil 3, preventing the steel coil from shifting due to external force during the adjustment process and ensuring stable adjustment. The components cooperate with each other and have a high degree of automation, which can greatly improve the steel coil shearing efficiency, reduce the intensity of manual labor, and ensure stable product quality. It is suitable for large-scale steel coil shearing production and has high practicality and economic value.

[0054] When the extrusion roller 47 rotates with the telescopic plate 43 to the middle of the support plate 4, the conical plate 424 on one side of the extrusion roller 47 contacts the protrusion 423. The protrusion 423 squeezes the conical plate 424 into the extrusion roller 47. At this time, the positioning hole 427 on the surface of the conical plate 424 is aligned with the fixing hole 425 on the circumferential surface of the rotating shaft 46. At this time, the anti-corrosion coating liquid in the storage box 5 is pressurized and passed from the connecting pipe 51 into the telescopic pipe 421, then from the telescopic pipe 421 into the fixing hole 425, and then flows into the positioning hole 427 to wet the adhesive block 422. Then the motor 44 drives the telescopic plate 43 to rotate. During the rotation, the gear 48 fixed to the circumferential surface of the rotating shaft 46 will rotate along the rack plate 49, thereby driving the extrusion roller 47 to rotate while sliding in an arc, so as to coat the surface of the roll 3.

[0055] When the extrusion roller 47 moves to the middle of the support plate 4, the protrusion 423 extrudes the cone plate 424 to align the positioning hole 427 with the fixing hole 425, allowing the anti-corrosion coating liquid to flow smoothly into the wetting and adhesion block 422, thus preparing for subsequent coating. When the motor 44 drives the telescopic plate 43 to rotate, the gear 48 and the rack plate 49 cooperate to make the extrusion roller 47 slide and rotate in an arc shape, which can uniformly and comprehensively coat the surface of the roll 3, improve the coating quality, effectively prevent the corrosion of the roll 3, extend the service life of the roll 3, and at the same time ensure the performance and stability of the roll 3 in subsequent processing and use.
