Description

Technical Field

[0001] This utility model belongs to the field of aluminum processing technology, and specifically relates to an aluminum coil longitudinal shearing structure. Background Technology

[0002] Slitting aluminum strip is a cutting process performed along the length of an aluminum strip to precisely cut a wide strip into several narrow strips. However, existing aluminum coil slitting equipment has a significant limitation: the cutting width of the aluminum strips cannot be flexibly adjusted. If a change in strip width is needed, the operator must replace the cutter shaft with one that matches the target width—a cumbersome and time-consuming process. Frequent cutter shaft replacements not only increase equipment wear and maintenance costs but also significantly reduce production efficiency.

[0003] Chinese utility model patent CN212469975U discloses an aluminum coil slitting structure. The cutter shaft assembly includes two cutter shafts arranged parallel to each other along their axes. Each cutter shaft has a cutter disc protruding radially. A vertically movable roller is arranged on the upper side of the cutter shaft assembly. The roller frame is pushed and pulled by a vertically telescopic first cylinder. The first cylinder's extension causes the roller to press against the aluminum coil between the two cutter shafts. The roller frame also engages with a machine frame via guide posts, and vertically arranged racks are mounted on the guide posts. The system includes a guide bar and gear meshing; a rolling assembly comprising a pressure plate positioned for vertical displacement; the pressure plate being pushed and pulled by a vertically extending second cylinder; sliders for clamping aluminum coils in the width direction arranged on both sides of the platform; the sliders engaging with a lead screw; a handwheel at the end of the lead screw; a guide assembly comprising a roller and a support plate; the roller engaging with the support plate to roll the aluminum coil; the support plate abutting the support plate; one end of the support plate being fixed to the frame via a rotating shaft; the rotating shaft being driven by a motor to flip the support plate from below to the horizontal direction to support the aluminum coil. However, it cannot adjust the spacing between the cutter heads on the cutter shaft, requiring replacement of the cutter shaft and affecting production efficiency. Utility Model Content

[0017] 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.

[0018] Example 1:

[0019] This utility model provides an aluminum coil slitting structure, including a frame 1, a workbench 2 fixedly mounted on the frame 1, a support plate 3 fixedly mounted on the workbench 2, a first cutter shaft 4, a second cutter shaft 5, and a roller shaft 6 movably mounted on the support plate 3, the first cutter shaft 4 and the second cutter shaft 5 being connected by a gear set 7, a first cutter disc 8 movably mounted on the first cutter shaft 4, and a second cutter disc 9 movably mounted on the second cutter shaft 5, both the first cutter shaft 4 and the second cutter shaft 5 having protruding ribs 10, and both the first cutter disc 8 and the second cutter disc 9 having grooves 11, the grooves 11 being movably engaged with the protruding ribs 10, and a first slide rail 12 and a second slide rail 13 fixedly mounted on the workbench 2. A first movable stage 15 is movably connected to a servo motor 14 and a first slide rail 12. The servo motor 14 drives the first movable stage 15 via a lead screw 16. A docking cylinder 17 and a laser receiver 18 are fixedly mounted on the first movable stage 15. The docking cylinder 17 drives a first docking plate 19, which has a docking notch 20. A second movable stage 21 is movably connected to a second slide rail 13. The second movable stage 21 has symmetrically arranged clamping plates 22, which movably clamp the first cutter head 8. A second docking plate 23 and a laser emitter 24 are fixedly mounted on the second movable stage 21. The second docking plate 23 has a docking protrusion 25. A roller 26 is movably mounted on the clamping plate 22, and the roller 26 movably abuts against the first cutter head 8. A first protective rubber ring 27 is fixedly mounted on the first cutter head 8, and a second protective rubber ring 28 is fixedly mounted on the second cutter head 9. The second moving platform 21 is fixedly installed with a fixed cylinder 29, which is driven by a fixed block 30. The bottom of the fixed block 30 is fixedly installed with an anti-slip pad 31.

[0020] Through the above technical solution, the support plate 3 of this utility model is movably mounted with a first cutter shaft 4 and a second cutter shaft 5. The first cutter shaft 4 and the second cutter shaft 5 are connected by a gear set 7. The first cutter shaft 4 is movably mounted with multiple sets of first cutter discs 8, and the second cutter shaft 5 is movably mounted with multiple sets of second cutter discs 9. The first cutter discs 8 and the second cutter shaft 5 are in a shearing cooperation to longitudinally cut the aluminum strip into aluminum strips. The servo motor precisely controls the movement of the first moving platform 15 through the lead screw 16, and receives the laser emitter 24 on the second moving platform 21 through the laser receiver 18, so that the docking notch 20 of the first moving platform 15 and the docking protrusion 25 of the second moving platform 21 are aligned. The positions are aligned, and then the first docking plate 19 is extended by the docking cylinder 17, so that the docking notch 20 and the docking protrusion 25 are inserted and fixed. The clamping plates 22 symmetrically arranged on the second moving table 21 clamp and fix one of the first cutter discs 8. The servo motor 14 drives the first moving disc to the designated position according to the preset data, and at the same time drives the second moving table 21 to move, thereby driving the first cutter disc 8 and the second cutter disc 9 to the set position, quickly completing the spacing adjustment of one cutter disc. By controlling the servo motor 14 and the docking cylinder 17, the spacing adjustment of all cutter discs can be completed automatically and quickly, shortening the machine adjustment time and improving production efficiency.

[0021] Example 2:

[0022] In this embodiment, a workbench 2 is fixedly mounted on the frame 1, serving as the basic support platform for the entire device. A support plate 3 is fixedly mounted on the workbench 2. The support plate 3 is made of high-strength steel and can withstand the enormous stress during the shearing process. A first cutter shaft 4 and a second cutter shaft 5 are movably mounted on the support plate 3. The two cutter shafts are arranged in parallel and are meshed together by a gear set 7, ensuring that the two cutter shafts rotate synchronously in opposite directions. Multiple first cutter discs 8 are movably mounted on the first cutter shaft 4, and multiple second cutter discs 9 are correspondingly mounted on the second cutter shaft 5. The cutter discs are made of cemented carbide material, possessing excellent wear resistance.

[0023] Both the first cutter shaft 4 and the second cutter shaft 5 have axially extending ribs 10 on their surfaces, with the ribs 10 having a trapezoidal cross-section. The inner holes of the first cutter disc 8 and the second cutter disc 9 have corresponding grooves 11, the shape of which matches the ribs 10, allowing the cutter discs to slide along the cutter shaft axis but not rotate relative to it. This mating structure of the ribs 10 and grooves 11 ensures torque transmission between the cutter discs and the cutter shafts while also enabling flexible adjustment of the cutter disc position.

[0024] A first slide rail 12 and a second slide rail 13 are fixedly installed on the worktable 2, and the two slide rails are arranged in parallel. A first moving stage 15 is movably connected to the first slide rail 12. A servo motor 14 drives the first moving stage 15 to move precisely along the slide rail through a precision ball screw 16. A docking cylinder 17 and a laser receiver 18 are fixedly installed on the first moving stage 15. The piston rod end of the docking cylinder 17 is connected to a first docking plate 19, and the first docking plate 19 has a V-shaped docking notch 20. A second moving stage 21 is movably connected to the second slide rail 13. Elastic clamping plates 22 are symmetrically arranged on both sides of the second moving stage 21. The inner side of the clamping plates 22 has anti-slip textures, which can firmly clamp the first cutter head 8. A second docking plate 23 and a laser emitter 24 are also fixedly installed on the second moving stage 21. The second docking plate 23 has a wedge-shaped docking protrusion 25 that mates with the docking notch 20.

[0025] The working principle of this structure is as follows: When the cutter head spacing needs to be adjusted, the servo motor 14 drives the first moving stage 15 to move, and the laser receiver 18 detects the position signal of the laser emitter 24 in real time to ensure that the docking notch 20 and the docking protrusion 25 are precisely aligned. The docking cylinder 17 pushes the first docking plate 19 to extend, so that the docking notch 20 and the docking protrusion 25 complete the insertion and engagement. At this time, the clamping plate 22 on the second moving stage 21 clamps and fixes the target cutter head, and the servo motor 14 drives the first moving stage 15 to move the second moving stage 21 according to the preset parameters, thereby adjusting the cutter head to the set position. After one cutter head adjustment is completed, the docking cylinder 17 retracts to separate the docking mechanism, and the system automatically performs the positioning adjustment of the next cutter head. The whole process realizes the automated and precise adjustment of the cutter head spacing, which significantly improves production efficiency.

[0026] The key innovation of this embodiment lies in the use of a laser-positioned automatic docking mechanism, coupled with a precision movement system driven by a servo motor 14, enabling rapid and accurate adjustment of the cutter head spacing. The matching design of the protruding rib 10 and the groove 11 ensures both the stability of the cutter head installation and facilitates position adjustment. The entire adjustment process does not require disassembling the cutter shaft or replacing parts, greatly shortening the equipment adjustment time and adapting to the production needs of aluminum strips of different specifications.

[0027] Example 3:

[0028] In this embodiment, the movable connection between the clamping plate 22 and the first cutter head 8 adopts a roller 26 structure. Specifically, a mounting groove is formed on the inner surface of the clamping plate 22, and multiple rollers 26 are movably mounted in this groove via bearings. These rollers 26 are evenly distributed along the circumference of the first cutter head 8, and the outer circumferential surface of each roller 26 maintains rolling contact with the side surface of the first cutter head 8. The axis of the roller 26 is parallel to the axis of the first cutter head 8, ensuring that the roller 26 can roll smoothly along the circumference of the first cutter head 8.

[0029] When the clamping plate 22 holds the first cutter head 8 for position adjustment, the roller 26 rolls along with the rotation of the first cutter head 8. This rolling contact method transforms traditional sliding friction into rolling friction, significantly reducing the coefficient of friction of the contact surface. The roller 26 is made of high-strength alloy steel, and its surface is hardened to improve wear resistance. The sides of the first cutter head 8 are also precision ground to ensure a high degree of smoothness on the contact surface with the roller 26.

[0030] During the slitting process, the first cutter head 8 needs to rotate frequently to complete the shearing operation. The roller 26 structure can effectively absorb the radial force generated when the cutter head rotates, avoiding direct friction between the clamping plate 22 and the cutter head. When the position of the cutter head needs to be adjusted, the servo motor 14 drives the moving table to move the clamping plate 22, and the roller 26 will roll smoothly on the surface of the cutter head, which not only ensures positioning accuracy but also reduces wear on the contact surface.

[0031] The rollers 26 are installed in a detachable structure for easy maintenance and replacement. Each roller 26 is equipped with an independent lubrication system, and grease can be added periodically through grease fittings to ensure smooth operation of the roller 26 bearings. The clamping plate 22 is also equipped with a wear detection device, which will issue a replacement prompt when the wear of the roller 26 reaches a predetermined value.

[0032] The roller 26 structure is particularly suitable for high-speed slitting operations. Under high-speed conditions, the roller 26 effectively suppresses vibration and maintains the stability of the cutter head. At the same time, the rolling contact method reduces operating noise and improves the working environment. Compared to traditional sliding contact methods, this design can extend the service life of the cutter head and clamping plate 22 by more than three times.

[0033] During prolonged continuous operation, the roller 26 structure exhibits excellent thermal stability. Due to a significant reduction in frictional heat generation, the temperature rise of the cutter head and clamping plate 22 is noticeably lower, avoiding the accuracy degradation caused by thermal deformation. This is crucial for maintaining the dimensional stability of the aluminum strip being cut.

[0034] The roller 26 structure of this embodiment is not only applicable to the first cutter head 8, but can also be applied to the clamping mechanism of the second cutter head 9. The symmetrically arranged roller 26 sets ensure a stable relative position between the upper and lower cutter heads during the shearing process, thereby improving shearing quality. The entire system significantly reduces maintenance costs and downtime while maintaining positioning accuracy.

[0035] Example 4:

[0036] In this embodiment, a first protective rubber ring 27 is fixedly installed on the first cutter head 8, and a second protective rubber ring 27 is fixedly installed on the second cutter head 9. These protective rubber rings are made of elastic rubber material and are tightly fitted around the circumferential edges of the first cutter head 8 and the second cutter head 9, respectively. The inner diameter of the protective rubber ring matches the outer diameter of the cutter head, achieving a secure fixation through an interference fit. When the first cutter head 8 and the second cutter head 9 mesh with each other during the shearing process, the protective rubber rings effectively buffer the direct contact between the cutter heads.

[0037] The working principle of the protective rubber ring is mainly reflected in two aspects: First, during the rotation of the cutter head, the elastic properties of the protective rubber ring can absorb some of the vibration energy, reducing rigid collisions between the cutter heads. When the cutter head undergoes slight displacement due to machining load, the protective rubber ring will undergo elastic deformation, avoiding direct metal-to-metal friction. Second, the protective rubber ring has a low surface friction coefficient, which can significantly reduce frictional resistance when the cutter heads come into contact with each other.

[0038] The protective rubber ring is specially designed to be positioned behind the cutting edge of the cutter head, ensuring it doesn't interfere with normal shearing function while providing full protection. As the cutter head rotates at high speed, the protective rubber ring remains on the cutter head's circumferential trajectory, forming a continuous protective band. This design ensures effective protection at any rotation angle.

[0039] The protective rubber ring also features a semi-circular cross-sectional shape. This streamlined design helps reduce air resistance and wind noise generated during high-speed rotation. Simultaneously, the semi-circular cross-section provides sufficient elastic deformation space, generating an appropriate buffering effect during cutter head engagement. The thickness of the protective rubber ring is precisely calculated to ensure sufficient protective performance without affecting the normal clearance between the cutter heads.

[0040] In actual operation, when the first cutter head 8 and the second cutter head 9 perform shearing actions, the protective rubber rings first come into contact, absorbing impact energy through elastic deformation. As the cutter heads continue to rotate, the protective rubber rings maintain stable contact pressure, forming a continuous shock-absorbing barrier. This design not only reduces mechanical noise but also reduces cutter head wear and extends tool life.

[0041] The protective rubber ring is made of materials that prioritize wear resistance and high-temperature resistance, ensuring stable physical properties during the high-temperature processing of aluminum. Its surface undergoes a special treatment to provide self-lubricating properties, further reducing the coefficient of friction. The protective rubber ring is double-fixed to the cutter head; in addition to an interference fit, a special adhesive is applied to the contact surface to ensure it will not detach during high-speed rotation.

[0042] The protective rubber rings are designed for ease of maintenance, featuring a modular structure that allows for individual replacement of damaged rings without needing to replace the entire cutter head. Replacing the protective rings is simple and quick: just peel off the old ring, clean the cutter head surface, and press in the new one. This design significantly reduces equipment maintenance costs and time.

[0043] Over long-term use, the protective rubber ring will gradually wear down, but at a much lower rate than the metal cutter head. When the protective rubber ring wears down to a certain extent, its vibration damping and noise reduction effect will significantly decrease, at which point it needs to be replaced promptly. The wear condition of the protective rubber ring can be assessed through visual inspection or specialized measuring tools to ensure timely maintenance.

[0044] Example 5:

[0045] The fixing device for the second moving stage 21 in this embodiment includes a fixing cylinder 29 fixedly installed on the second moving stage 21. A fixing block 30 is connected to the piston rod end of the fixing cylinder 29, and an anti-slip pad 31 is embedded in the bottom of the fixing block 30. When the second moving stage 21 needs to move along the second slide rail 13 to adjust the cutter head spacing, the fixing cylinder 29 is in a retracted state. At this time, the fixing block 30 maintains a certain distance from the worktable 2, ensuring that the second moving stage 21 can slide freely.

[0046] During the adjustment of the cutter head spacing, the servo motor 14 drives the first moving stage 15 to move via the lead screw 16. The laser receiver 18 on the first moving stage 15 cooperates with the laser emitter 24 on the second moving stage 21 to achieve precise positioning. When the docking notch 20 of the first moving stage 15 aligns with the docking protrusion 25 of the second moving stage 21, the docking cylinder 17 pushes the first docking plate 19 to extend, so that the docking notch 20 and the docking protrusion 25 are inserted and fixed. At this time, the clamping plate 22 on the second moving stage 21 clamps and fixes the first cutter head 8.

[0047] After the cutter head spacing is adjusted, the fixing cylinder 29 starts working, the piston rod extends outward, and pushes the fixing block 30 downward. The anti-slip pad 31 at the bottom of the fixing block 30 contacts the surface of the worktable 2 and generates a pressing force. The anti-slip pad 31 is made of a high-friction coefficient material, which can effectively increase the friction between the fixing block 30 and the worktable 2. Under the continuous pressure of the fixing cylinder 29, the anti-slip pad 31 undergoes slight deformation and forms a tight fit with the surface of the worktable 2, thereby firmly fixing the second moving stage 21 to the worktable 2.

[0048] The working principle of this fixing device is to use the mechanical pressure generated by the cylinder to press the anti-slip pad 31 firmly against the surface of the worktable 2, using friction to prevent any displacement of the second moving stage 21 during the cutting process. The elastic properties of the anti-slip pad 31 allow it to adapt to minor unevenness on the surface of the worktable 2, ensuring maximum contact area. When it is necessary to readjust the cutter head spacing, the fixing cylinder 29 retracts, releasing the fixation of the second moving stage 21, allowing for the next position adjustment.

[0049] This fixing method features rapid response and simple operation. The action of the fixing cylinder 29 is linked to the control system of the entire slitting structure, automatically executing the fixing operation after position adjustment, without manual intervention. The anti-slip pad 31 is designed to ensure sufficient friction while avoiding surface damage that may be caused by direct metal contact. The entire fixing process does not adversely affect the slitting accuracy; on the contrary, it ensures the stability of the cutter head position during cutting, thereby improving the accuracy and product quality of aluminum strip slitting.

[0050] This embodiment demonstrates how a reliable fixation of the second moving table 21 can be achieved through a simple cylinder drive mechanism in conjunction with the anti-slip pad 31 design. This fixing method works in coordination with other components of the slitting structure to form a complete cutter head spacing adjustment system, solving the problem of traditional equipment requiring the replacement of the cutter shaft to adjust the shearing width, and significantly improving production efficiency and ease of operation.
