Description

Technical Field

[0001] This invention relates to the field of deburring technology, specifically to a steel strip edge trimming and deburring device. Background Technology

[0002] In industries such as metallurgy, metal product processing, and new energy, cold-rolled, galvanized, and stainless steel strips are widely used. To meet the width precision requirements of downstream industries, steel strips typically undergo slitting (edge ​​trimming) to cut wide master coils into several narrow strips. However, during the shearing process, due to the gap between the upper and lower cutter discs and the plastic deformation and tearing of the material, unavoidable linear burrs with a certain height and hardness are generated at the edges of the sheared surface of the steel strip. Currently, the industry generally uses online scraper devices for deburring, such as those authorized in announcement number CN2135610. 21U discloses a cutting and deburring device for steel edges, including a worktable. Two support plates are vertically fixed from left to right on the upper part of the worktable. A fixing device is provided above the support plates. A cutting device is provided on the upper right side of the worktable. A groove is provided in the cutting device. Steel strip through holes are symmetrically provided on the side walls on the left and right sides of the groove. An mounting plate is movably installed in the cutting device. A lower grinding plate and an upper grinding plate are provided on the left side of the mounting plate. The mounting plate is moved back and forth by the extension and retraction of a first telescopic rod, so that the upper grinding plate and the lower grinding plate deburr the steel edge during the movement.

[0003] Existing deburring equipment typically uses scrapers installed on both sides of the worktable during the steel strip winding process to scrape the burrs off the edges of the moving steel strip. Because the steel strip is narrow after slitting (edge ​​trimming), the distance between the two scrapers is also relatively small. During operation, the equipment often uses a blower to remove the debris generated by scraping. However, the actual material removed is mostly thin, long steel wire-like debris, which is not easily blown away completely due to its shape and airflow. These debris tend to accumulate gradually in the narrow gap between the scrapers, forming clumps. The continuously accumulating steel wire clumps rub against each other as the steel strip is conveyed, easily causing large-area scratches on the surface of the steel strip, seriously affecting the surface quality of the material. Currently, manual on-site cleaning is generally relied upon to alleviate this problem, but due to the narrow gap between the scrapers, the cleaning operation is extremely inconvenient. In addition, since the steel strip is in a continuous running state, there is a safety hazard of hand cuts when personnel intervene in the cleaning, which not only affects the work efficiency but also poses a significant risk to production safety. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a steel strip edge trimming and deburring device that can achieve functions such as spacing control, alternating operation, and automatic switching of deburring scrapers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel strip trimming and deburring device, comprising a cutting table and a processing table fixed to one side of the cutting table. Four sets of slide rails are fixedly installed on the processing table. A connecting housing is slidably mounted on each set of slide rails. A hexagonal plate is rotatably mounted on the connecting housing. Multiple deburring scrapers are fixedly mounted at equal intervals around the periphery of the hexagonal plate. The deburring scrapers on adjacent sets of connecting housings work in batches. A push block is fixedly installed at the lower end of each connecting housing. A rotating component for controlling the movement of the push block is rotatably mounted inside the processing table. A telescopic component is provided between the connecting housing and the slide rails. The rotating component works to control the movement of two sets of connecting housings while simultaneously releasing the limits on the other two sets of connecting housings. A rotating column rotatably connected to the connecting housing is fixedly installed at the lower end of the hexagonal plate. A pushing component for controlling the rotation of the hexagonal plate is provided inside the connecting housing. A limit connector is provided between the rotating column and the connecting housing to control the unidirectional rotation of the hexagonal plate. A positioning component for positioning the hexagonal plate is also provided inside the connecting housing.

[0006] Preferably, it also includes a lifting cutting blade fixedly mounted on the cutting table.

[0007] Preferably, the rotating component includes two rotating rods rotatably mounted on the inner wall of the processing table. Two first semicircular plates and two second semicircular plates are fixedly mounted on the rotating rods. A motor is fixedly mounted on the processing table, and a power connection is provided between the motor and the two rotating rods.

[0008] Preferably, the motor output end is fixedly connected to one of the rotating rods, the power connector includes a rotating gear ring fixedly sleeved on the other rotating rod, connecting gear rings are fixedly installed on the inner wall of the processing table and on the rotating rod connected to the motor, one of the connecting gear rings meshes with the rotating gear ring, a sawtooth belt is sleeved between the two connecting gear rings, a protective shell is fixedly installed on the inner wall of the processing table, and the connecting gear ring, rotating gear ring and sawtooth belt are all located inside the protective shell.

[0009] Preferably, the telescopic component includes a rectangular sleeve fixedly installed on the slide rail, a rectangular slider slidably disposed inside the rectangular sleeve, a return spring fixedly installed between the rectangular slider and the slide rail, one end of the rectangular slider being fixedly connected to a connecting housing corresponding to the position, and a limit rod being fixedly installed at the other end of the rectangular slider.

[0010] Preferably, the limiting connector includes a one-way bearing fixedly sleeved on the rotating column, wherein the inner ring of the one-way bearing is fixedly sleeved on the rotating column, and the outer ring is fixedly connected to the upper wall of the connecting housing.

[0011] Preferably, the pushing component includes a fixed toothed ring fixedly sleeved on the rotating column, a connecting plate fixedly installed on the slide rail, one end of the connecting plate located inside the connecting housing, a toothed block slidably disposed on the connecting housing that meshes with the fixed toothed ring, and an inclined telescopic component disposed between the toothed block and the slide rail.

[0012] Preferably, the telescopic assembly includes an inclined cylinder fixedly connected to the side wall of the slide rail, a T-shaped inclined rod fixedly connected to one side of the toothed block and slidably connected to the inclined cylinder, and a connecting spring fixedly provided between the T-shaped inclined rod and the inclined cylinder.

[0013] Preferably, the positioning component includes an inner convex ring fixedly installed on the upper wall of the connecting housing, a circular ring fixedly sleeved on the outer side of the rotating column, and multiple arc-shaped spring pieces corresponding to the positions of the inner convex ring fixedly installed at equal intervals on the outer side of the circular ring, and a first locking block and a second locking block fixedly installed on the connecting plate to limit the position of the fixed toothed ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention employs a four-set independent slide rail structure, with a movable connecting housing on each set of slide rails. By adjusting the displacement of the connecting housing on the slide rail, the working distance between the paired deburring scrapers can be flexibly adjusted, facilitating the cleaning of steel wire debris accumulated in the gap between the deburring scrapers. A push block is fixedly installed below the connecting housing. When the control drive rod rotates, it drives the first and second semicircular plates to act on the corresponding push blocks in sequence, enabling the deburring scrapers carried by the adjacent two sets of connecting housings to alternately enter the working state. This design allows the system to perform debris cleaning operations on one set of deburring scrapers without interrupting the production line operation, while the other set of deburring scrapers continues to complete the deburring processing task, thereby significantly improving the continuous operation capability and production efficiency of the equipment.

[0015] 2. This invention installs a rotating column at the lower end of a hexagonal plate. The rotating column is rotatably connected to the connecting housing via a one-way bearing. A fixed toothed ring on the rotating column meshes with a toothed block. One side of the toothed block is slidably connected to an inclined cylinder on the side of the slide rail via a T-shaped inclined rod. This allows the fixed toothed ring to shift when the connecting housing is moved and the distance between the two deburring scrapers is widened. Based on the one-way transmission characteristics of the fixed toothed ring and the toothed block, the movement of the fixed toothed ring will push the toothed block to shift, and the T-shaped inclined rod will then compress the connecting spring. When the distance between the two deburring scrapers is narrowed, the fixed toothed ring and the toothed block re-mesh and drive the rotating column to rotate, which in turn drives the hexagonal plate to rotate. This allows for the switching of the deburring scraper and the spare deburring scraper between workstations. This system allows worn deburring scrapers to be safely disassembled and replaced when not in a workstation, thus ensuring the continuity of deburring operations and the convenience of tool management.

[0016] 3. This invention uses a first and a second locking block fixedly installed on a connecting plate to bidirectionally limit the fixed toothed ring. When it is necessary to widen the distance between the two deburring scrapers, the second locking block provides positioning constraint to the fixed toothed ring. When the scraper distance is narrowed, the first locking block performs the limiting action. In the limiting state, the hexagonal plate is locked and cannot rotate, thus ensuring that the worn deburring scraper at the non-working position can be safely disassembled and replaced. At the same time, the deburring scraper structure in the working position remains stable to ensure the continuous operation of the deburring process. In addition, through the cooperation structure of the inner convex ring and the arc-shaped spring, the hexagonal plate can be controlled at a fixed angle each time the tool is switched, so that the first and second locking blocks can accurately mesh and perform the limiting function. This design also ensures that the hexagonal plate can maintain a stable position in the non-limiting state, avoiding spontaneous rotation and improving the reliability of equipment operation.

Detailed Implementation

[0019] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0020] Please see Figures 1-8 A steel strip trimming and deburring device includes a cutting table 1 and a processing table 3 fixed to one side of the cutting table 1. It also includes a lifting cutting blade 2 fixedly mounted on the cutting table 1 for cutting during the winding process (this is existing technology, generally consisting of a hydraulic rod and a cutting blade). Four sets of slide rails 5 are fixedly mounted on the processing table 3 (the number of slide rails 5 can be set according to the size of the processing table 3, and any multiple of four is acceptable). A connecting housing 7 is slidably mounted on each set of slide rails 5. A hexagonal plate 6 is rotatably mounted on the connecting housing 7. Multiple deburring scrapers 9 (which can be fixed with bolts) are fixedly mounted at equal intervals around the hexagonal plate 6. Three deburring scrapers 9 are installed. The deburring scrapers 9 on the two adjacent sets of connecting housings 7 work in batches. Push blocks 18 are fixedly installed at the lower end of each connecting housing 7. A rotating component is rotatably installed inside the processing table 3 to control the movement of the push blocks 18. A telescopic component is provided between the connecting housing 7 and the slide rail 5. The rotating component works to control the movement of two sets of connecting housings 7 and release the limit on the other two sets of connecting housings 7. The rotating component includes two rotating rods 12 rotatably installed on the inner wall of the processing table 3. Two first semicircular plates 19 and two second semicircular plates 20 are fixedly installed on the rotating rods 12. A motor is fixedly installed on the processing table 3. 4. A power connection is provided between the motor 4 and the two rotating rods 12. The telescopic component includes a rectangular sleeve 8 fixedly installed on the slide rail 5. A rectangular slider 10 is slidably arranged inside the rectangular sleeve 8. A return spring 17 is fixedly installed between the rectangular slider 10 and the slide rail 5. One end of the rectangular slider 10 is fixedly connected to the corresponding connecting housing 7, and a limit rod 16 is fixedly installed on the other end of the rectangular slider 10. The operation of the motor 4 controls the rotation of the two rotating rods 12. The rotating rods 12 drive multiple first semicircular plates 19 and second semicircular plates 20 to rotate synchronously. The first semicircular plates 19 and second semicircular plates 20 push the push block 18 to move. To adjust the displacement of the connecting housing 7 on the slide rail 5, after the first semicircular plate 19 and the second semicircular plate 20 disengage from the push block 18, the connecting housing 7 is pulled back to its original position by the return spring 17 until the limit rod 16 abuts against the slide rail 5, and the reset is completed. This allows for flexible adjustment of the working distance between the paired deburring scrapers 9, thus facilitating the cleaning of steel wire debris accumulated in the gaps between the deburring scrapers 9. When the control drive rod 12 rotates, it drives the first semicircular plate 19 and the second semicircular plate 20 to act on the corresponding push block 18 in sequence, realizing that the deburring scrapers 9 carried by the two adjacent sets of connecting housings 7 alternately enter the working state (see...). Figure 7 and Figure 8As can be seen, during the synchronous pushing of two adjacent push blocks 18, at the instant the deburring scraper 9 completes the switching, the two push blocks 18 are in the same position. At this time, the two adjacent deburring scrapers 9 converge at the workstation. The deburring scraper 9 in the non-workstation position moves accurately to the working position, while the deburring scraper 9 originally in the workstation position begins to move away. That is, the deburring scraper 9 in the non-workstation position moves to the workstation position, and the deburring scraper 9 in the workstation position leaves. This design ensures that the deburring scraper 9 in the non-working state can be accurately positioned and locked on the outside of the steel strip, realizing continuous positioning and seamless connection during the tool switching process. This design allows the system to perform debris cleaning operation on one set of deburring scrapers 9 without interrupting the production line operation, while the other set of deburring scrapers 9 takes over to complete the deburring processing task, thereby significantly improving the continuous operation capability and production efficiency of the equipment. A rotating column 14, rotatably connected to a connecting housing 7, is fixedly installed at the lower end of a hexagonal plate 6. A pushing component for controlling the rotation of the hexagonal plate 6 is provided inside the connecting housing 7. A limiting connector is provided between the rotating column 14 and the connecting housing 7 to control the unidirectional rotation of the hexagonal plate 6. The limiting connector includes a one-way bearing 29 fixedly sleeved on the rotating column 14. The inner ring of the one-way bearing 29 is fixedly sleeved on the rotating column 14, and the outer ring is fixedly connected to the upper wall of the connecting housing 7. The pushing component includes a fixed toothed ring 15 fixedly sleeved on the rotating column 14. A connecting plate 11 is fixedly installed on the slide rail 5, with one end of the connecting plate 11 located inside the connecting housing 7. A toothed block 23, meshing with the fixed toothed ring 15, is slidably arranged on the connecting housing 7. An inclined telescopic assembly is provided between the toothed block 23 and the slide rail 5. The telescopic assembly includes an inclined cylinder 24 fixedly connected to the side wall of the slide rail 5. One side of the toothed block 23 is fixedly connected to the inclined cylinder 24. 4. A sliding T-shaped inclined rod 22 is connected to the inclined cylinder 24. A connecting spring 25 is fixedly installed between the T-shaped inclined rod 22 and the inclined cylinder 24. When the connecting housing 7 is moved to widen the gap between the two deburring scrapers 9, the fixed toothed ring 15 is displaced accordingly. Based on the unidirectional transmission characteristics of the fixed toothed ring 15 and the toothed block 23, the movement of the fixed toothed ring 15 will push the toothed block 23 to move, and the T-shaped inclined rod 22 will then compress the connecting spring 25. When the gap between the two deburring scrapers 9 is narrowed, the fixed toothed ring 15 and the toothed block 23 re-mesh and drive the rotating column 14 to rotate, driving the hexagonal plate 6 to rotate, realizing the switching of the deburring scraper 9 with the spare deburring scraper 9. This system allows the worn deburring scraper 9 to be safely disassembled and replaced in a non-working state, thereby ensuring the continuity of deburring operation and the convenience of tool management. The connecting housing 7 is also equipped with a positioning component for positioning the hexagonal plate 6.

[0021] As a further technical solution of the present invention, the output end of the motor 4 is fixedly connected to one of the rotating rods 12. The power connection includes a rotating gear ring 32 fixedly sleeved on the other rotating rod 12. A connecting gear ring 31 is fixedly installed on the inner wall of the processing table 3 and on the rotating rod 12 connected to the motor 4. One of the connecting gear rings 31 meshes with the rotating gear ring 32. A sawtooth belt 13 is sleeved between the two connecting gear rings 31. A protective shell 30 is fixedly installed on the inner wall of the processing table 3. The connecting gear ring 31, the rotating gear ring 32 and the sawtooth belt 13 are all located inside the protective shell 30. The rotating rod 12 is rotatably connected to the protective shell 30. When the motor 4 is started, multiple sets of connecting shells 7 can be synchronously controlled through the cooperation of the connecting gear ring 31, the rotating gear ring 32 and the sawtooth belt 13.

[0022] As a further technical solution of the present invention, the positioning component includes an inner convex ring 28 fixedly installed on the upper wall of the connecting housing 7, a circular ring 27 fixedly sleeved on the outer side of the rotating column 14, and multiple arc-shaped spring pieces 33 corresponding to the positions of the inner convex ring 28 fixedly installed at equal intervals on the outer side of the circular ring 27 (the inner convex ring 28 is an annular plate and multiple arc-shaped protrusions are fixedly installed at equal intervals on the inner wall of the annular plate; the number of arc-shaped protrusions and arc-shaped spring pieces 33 is matched with the number of locking teeth of the fixed toothed ring 15 and the locking teeth of the toothed block 23; for example, the fixed toothed ring 15 has nine locking teeth and the toothed block 23 has three locking teeth, and one engagement rotates one-third of a turn, so the number of arc-shaped protrusions and arc-shaped spring pieces 33 can be twelve, a multiple of three, and rotates one-third of a turn synchronously). A first locking block 21 and a second locking block 26 for limiting the fixed toothed ring 15 are fixedly installed on the connecting plate 11. When expansion is required... When the distance between the two deburring scrapers 9 is increased, the second locking block 26 provides positioning constraint to the fixed toothed ring 15. When the distance between the two deburring scrapers 9 is decreased, the first locking block 21 performs a limit switch. In the limit switch state, the hexagonal plate 6 is locked and cannot rotate, thus ensuring that the worn deburring scraper 9 at the non-working position can be safely disassembled and replaced. At the same time, the structure of the deburring scraper 9 in the working position is kept stable to ensure the continuous operation of the deburring process. In addition, through the cooperation structure of the inner convex ring 28 and the arc-shaped spring piece 33, the hexagonal plate 6 can be controlled at a fixed angle each time the tool is switched and rotated, so that the first locking block 21 and the second locking block 26 can accurately mesh and perform the limit switch function. This design also ensures that the hexagonal plate 6 can maintain a stable position in the non-limit switch state, avoids spontaneous rotation, and improves the reliability of equipment operation.

[0023] During work: Phase 1: Initial Work Deburring: When the steel strip after slitting and cutting passes through the deburring scraper 9, it is scraped to remove burrs. At this time, there are two sets of deburring scrapers 9 (for example, numbered as group a and group c, and groups b and d are not working). The fine and long steel wire-like debris produced by scraping is easy to accumulate in the narrow gap between the pairs of deburring scrapers 9. Some debris will be blown away by the external blower. Phase Two: Switching When it is necessary to clean the wire-like debris between the deburring scrapers 9 of groups A and C, start the motor 4. The motor 4 drives the two rotating rods 12 to rotate synchronously through the power connector consisting of the connecting toothed ring 31, the rotating toothed ring 32 and the toothed belt 13; The rotating rod 12 drives the first semicircular plate 19 and the second semicircular plate 20 to rotate. At the beginning, the first semicircular plate 19 keeps the push block 18 below the connecting housing 7 of group a and group c in a limited state. At the same time, the second semicircular plate 20 rotates and then begins to contact and push the push block 18 below the connecting housing 7 of group b and group d. The corresponding connecting housing 7 drives the deburring scraper 9 on it to move along the slide rail 5, bringing the gap between the pair of deburring scrapers 9 closer, until the deburring scrapers 9 of group b and group d are moved to the work position. At this time, the push block 18 of group a and group c disengages from the first semicircular plate 19. Due to the action of the return spring 17, the corresponding connecting housing 7 is pulled to move, which drives the deburring scraper 9 to leave the steel strip, and its gap is exposed, which is convenient for debris cleaning. During the movement of the connecting housing 7 of groups a and c (increasing the spacing), the fixed toothed ring 15 fixed on the rotating column 14 moves accordingly. Since the rotating column 14 is connected to the connecting housing 7 through the one-way bearing 29, the one-way bearing 29 is locked at this time. The rotating column 14 and the hexagonal plate 6 cannot rotate. The movement of the fixed toothed ring 15 pushes the toothed block 23 that meshes with it to slide, and the connecting spring 25 on the compression T-shaped inclined rod 22 is squeezed. After the fixed toothed ring 15 disengages from the toothed block 23, the compressed connecting spring 25 is released, driving the toothed block 23 to reset. During the movement of the connecting housing 7 of groups b and d (reducing the distance), the fixed toothed ring 15 fixed on the rotating column 14 moves accordingly. The fixed toothed ring 15 meshes with the toothed block 23 and drives the fixed toothed ring 15 and the rotating column 14 to rotate by a fixed angle. The rotating column 14 drives the hexagonal plate 6 to rotate, thereby switching a new, unworn spare deburring scraper 9 to the working position, while turning the worn deburring scraper 9 away from the working position. Phase Three: Precise Positioning and Stability Maintenance The rotation angle of the hexagonal plate 6 is controlled by the cooperation of the inner convex ring 28 and the arc-shaped spring piece 33, as well as the fixed toothed ring 15 and the toothed block 23, ensuring that the rotation angle is fixed each time (e.g., 120°). When the connecting housing 7 is in the working position, the first locking block 21 will accurately engage in the tooth groove of the fixed toothed ring 15 to achieve circumferential limitation of the hexagonal plate 6, preventing it from rotating during operation and ensuring scraping stability. When the connecting housing 7 is in the non-working position, the second locking block 26 will accurately engage in the tooth groove of the fixed toothed ring 15 to achieve circumferential limitation of the hexagonal plate 6, preventing it from rotating and ensuring the stability of changing the deburring scraper 9. The deburring scrapers 9 of groups a and c, which have been moved out of their workstations and have increased spacing, can easily clean up the accumulated debris. At the same time, because the hexagonal plate 6 has been rotated, the worn scrapers have been moved to an easily accessible position outside the workstation, allowing for safe disassembly and replacement.

[0024] The above process constitutes a complete cycle. The motor 4 rotates continuously and intermittently, which controls the deburring scrapers 9 of (groups a, c) and (groups b, d) to alternately enter the working state and the cleaning and maintenance state.

[0025] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the claims of the present invention.
