[0016] 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.
[0017] Example 1:
[0018] This utility model provides a slitting device for aluminum plate production, including a main frame 1, a worktable 2 fixedly mounted on the main frame 1, an upper frame 3 fixedly mounted on the worktable 2, and a primary slitting mechanism 4 and a secondary slitting mechanism 5 fixedly mounted on the upper frame 3. The primary slitting mechanism 4 includes primary slitting rollers 6 arranged symmetrically on both sides and a primary drive device 7. The primary slitting rollers 6 are provided with pressure strips 8. The secondary slitting mechanism 5 includes secondary slitting rollers 9 arranged symmetrically on both sides and a secondary drive device 10. The secondary slitting rollers 9 are fixedly connected to cutting blades 11, and the number of pressure strips 8 and cutting blades 11 is equal. The distance between the pressure strips 8 of the primary slitting rollers 6 is equal to half the thickness of the aluminum plate to be processed, and the cutting blades 11 of the secondary slitting rollers 9 shear and mesh with each other. The secondary slitting rollers 9 are provided with a first slot 12, which is fixedly connected to the cutting blades 11, and the cutting blades 11 are made of tungsten steel. The pressure strip 8 is provided with a second slot 13, and a reinforcing member 14 is fixedly installed in the second slot 13. The reinforcing member 14 is made of tungsten steel.
[0019] Through the above technical solution, this utility model first uses the primary slitting mechanism 4 to press and cut deep marks into the aluminum plate, and then uses the secondary slitting mechanism 5 to cut into the deep marks and cut the aluminum plate. During operation, the primary drive device 7 drives the primary slitting rollers 6, which are symmetrically arranged on the upper and lower sides, to run, and the secondary drive device 10 drives the secondary slitting rollers 9, which are symmetrically arranged on the upper and lower sides, to run. The aluminum plate first passes through the primary slitting rollers 6. As the upper and lower primary slitting rollers 6 rotate synchronously, the pressure bar 8 presses and cuts the aluminum plate, leaving deep marks on the aluminum plate. The aluminum plate continues to be conveyed forward and passes through the secondary slitting rollers 9. The cutting blades 11 of the upper and lower primary slitting rollers 6 cut the deep marks on the aluminum plate, quickly cutting the aluminum plate and improving the processing efficiency of the aluminum plate.
[0020] Example 2:
[0021] This embodiment mainly consists of a main frame 1, a worktable 2, an upper frame 3, a primary slitting mechanism 4, and a secondary slitting mechanism 5. The main frame 1 serves as the supporting structure for the entire equipment, with a stable mounting base at its bottom to ensure the stability of the equipment during operation. The worktable 2 is fixedly installed on the upper part of the main frame 1, made of high-strength steel, and its surface is precision-machined to ensure flatness. The upper frame 3 is vertically fixed to the rear side of the worktable 2, forming the main frame structure of the equipment.
[0022] The primary slitting mechanism 4 is installed at the front of the upper frame 3, and includes primary slitting rollers 6 arranged symmetrically on the upper and lower sides and a primary drive unit 7. The upper and lower primary slitting rollers 6 are mounted on the frame by precision bearings, maintaining a parallel opposing relationship. The primary drive unit 7 uses a servo motor in conjunction with a reduction gear mechanism, and is connected to the primary slitting rollers 6 through a coupling to achieve precise speed control. Several pressure strips 8 are evenly distributed axially on the surface of the primary slitting rollers 6. The pressure strips 8 are made of high-strength alloy material and have a trapezoidal cross-section, which facilitates the application of concentrated pressure to the aluminum plate.
[0023] The secondary slitting mechanism 5 is located at the rear of the upper frame 3, maintaining a certain distance from the primary slitting mechanism 4. This mechanism also includes symmetrically arranged secondary slitting rollers 9 and a secondary drive unit 10. The secondary slitting rollers 9 are mounted via precision bearings and maintain a parallel relationship with the primary slitting rollers 6. The secondary drive unit 10 uses an independently controlled servo system to ensure precise synchronization of the cutting action. Cutting blades 11 are fixedly mounted on the secondary slitting rollers 9. The number of cutting blades 11 corresponds exactly to the pressure strips 8 of the primary slitting mechanism 4, and their installation positions are precisely calibrated to ensure that the cutting blades 11 can accurately align with the indentation positions formed by the pressure strips 8.
[0024] When the equipment is working, the aluminum sheet enters from the front end of the worktable 2 and first passes through the primary slitting mechanism 4. The upper and lower primary slitting rollers 6 rotate synchronously under the drive of the drive unit, and the pressure strip 8 applies pressure to the passing aluminum sheet, forming continuous indentations on the surface of the aluminum sheet. These indentations reduce the strength of the aluminum sheet at that location, preparing it for subsequent cutting. The aluminum sheet continues to be conveyed forward into the secondary slitting mechanism 5 area. At this time, the upper and lower secondary slitting rollers 9 drive the cutting blade 11 to rotate, and the cutting blade 11 precisely aligns with the indentation position to cut. Because the aluminum sheet has been weakened at the indentation, the cutting blade 11 can more easily complete the cutting action, greatly improving cutting efficiency.
[0025] The key to this equipment lies in the coordinated operation of the primary slitting mechanism 4 and the secondary slitting mechanism 5. The strict correspondence between the pressure strip 8 and the cutting blade 11 ensures the accuracy of the cutting position, while the step-by-step indentation and cutting processes significantly improve cutting speed and quality. The equipment adopts a modular design, allowing for adjustment of the number and spacing of the pressure strip 8 and the cutting blade 11 according to the production needs of aluminum sheets of different specifications, thus exhibiting excellent adaptability. The entire cutting process is continuous and requires no interruption, achieving highly efficient slitting of aluminum sheets.
[0026] Example 3:
[0027] In this embodiment, a workbench 2 is fixedly installed on the main frame 1, and an upper frame 3 is fixedly installed on the workbench 2. A primary slitting mechanism 4 and a secondary slitting mechanism 5 are sequentially arranged on the upper frame 3, and the two are arranged along the aluminum plate conveying direction.
[0028] The primary slitting mechanism 4 includes primary slitting rollers 6 arranged symmetrically at the top and bottom, and a primary drive unit 7. Several pressure strips 8 are evenly arranged on the circumferential surface of the two primary slitting rollers 6, extending axially along the rollers. The distance between the pressure strips 8 on the upper and lower primary slitting rollers 6 is set to half the thickness of the aluminum sheet to be processed, thus creating an indentation on the aluminum sheet surface with a depth approximately half the sheet thickness. The primary drive unit 7 adopts a synchronous drive method to ensure that the two primary slitting rollers 6 rotate synchronously.
[0029] The secondary slitting mechanism 5 is located downstream of the primary slitting mechanism 4, and includes symmetrically arranged secondary slitting rollers 9 and a secondary drive device 10. Cutting blades 11 are fixedly mounted on the secondary slitting rollers 9. The number of cutting blades 11 is equal to the number of pressure strips 8 on the primary slitting rollers 6, and their positions correspond one-to-one. The cutting blades 11 of the upper and lower secondary slitting rollers 9 adopt a mutually shearing and meshing design, meaning that the cutting blades 11 of the upper roller and the lower roller form a shearing action during rotation.
[0030] When the equipment is working, the aluminum sheet first passes through the primary slitting mechanism 4. Driven by the primary drive device 7, the upper and lower primary slitting rollers 6 rotate synchronously, and the pressure strips 8 on them apply pressure to the aluminum sheet, forming indentations on the surface of the aluminum sheet with a depth of about half the thickness of the sheet. These indentations provide guidance and stress concentration points for the subsequent shearing process.
[0031] Subsequently, the indented aluminum sheet enters the secondary slitting mechanism 5. Driven by the secondary drive device 10, the upper and lower secondary slitting rollers 9 rotate synchronously, and the cutting blades 11 on them cut along the indentation positions on the aluminum sheet. Due to the interlocking design of the cutting blades 11, the aluminum sheet can be cleanly and efficiently cut along the indentation positions. This two-step slitting method of indenting first and then cutting greatly improves the slitting efficiency and quality of the aluminum sheet.
[0032] Throughout the slitting process, the synchronization of the primary slitting mechanism 4 and the secondary slitting mechanism 5 is crucial. By precisely controlling the rotational speed and phase of the two mechanisms, it is ensured that the indentation formed by the pressure strip 8 is accurately aligned with the position of the subsequent cutting blade 11, thereby achieving efficient and precise slitting operations. This equipment is particularly suitable for the rapid slitting needs in high-volume aluminum plate production.
[0033] Example 4:
[0034] In this embodiment, a main frame 1 is fixedly mounted with a worktable 2, and an upper frame 3 is fixedly mounted on the worktable 2. The upper frame 3 is fixedly mounted with a primary slitting mechanism 4 and a secondary slitting mechanism 5. The primary slitting mechanism 4 includes primary slitting rollers 6 arranged symmetrically vertically and a primary drive device 7. The primary slitting rollers 6 are equipped with pressure strips 8. The secondary slitting mechanism 5 includes secondary slitting rollers 9 arranged symmetrically vertically and a secondary drive device 10. Cutting blades 11 are fixedly connected to the secondary slitting rollers 9. The number of pressure strips 8 and cutting blades 11 is equal to ensure that the cutting positions of the pressure strips 8 and cutting blades 11 are synchronized. The secondary slitting rollers 9 are equipped with a first slot 12, which is fixedly connected to the cutting blades 11. The cutting blades 11 are made of tungsten steel, facilitating the replacement of the cutting blades 11.
[0035] The working principle of this slitting equipment is as follows: During operation, the primary drive device 7 drives the symmetrically arranged primary slitting rollers 6, and the secondary drive device 10 drives the symmetrically arranged secondary slitting rollers 9. The aluminum sheet first passes through the primary slitting rollers 6. As the upper and lower primary slitting rollers 6 rotate synchronously, the pressure strip 8 cuts the aluminum sheet, leaving deep marks. The aluminum sheet continues to be conveyed forward, passing through the secondary slitting rollers 9. The cutting blades 11 of the upper and lower primary slitting rollers 6 cut at the deep marks on the aluminum sheet, quickly slitting the aluminum sheet and improving the processing efficiency.
[0036] The design of the first slot 12 allows for easy installation and removal of the cutting blade 11. When the cutting blade 11 wears out or needs replacement, simply remove the old cutting blade 11 from the first slot 12 and insert the new cutting blade 11 into the first slot 12 to complete the replacement. This design greatly simplifies the maintenance and replacement process of the cutting blade 11, reduces equipment downtime, and improves production efficiency.
[0037] The cutting blade 11 is made of tungsten steel, which has high hardness, high wear resistance, and good heat resistance. When cutting aluminum plates at high speed, the tungsten steel cutting blade 11 can maintain its sharpness, reduce wear, and extend its service life. At the same time, the high strength of tungsten steel also ensures that the cutting blade 11 is not easily deformed or broken when subjected to large cutting forces, guaranteeing cutting quality and the stability of equipment operation.
[0038] The symmetrically arranged primary slitting rollers 6 and secondary slitting rollers 9 ensure uniform force distribution on the aluminum sheet during cutting. The pressure bar 8 of the primary slitting roller 6 forms a deep groove on the aluminum sheet, providing accurate guidance for subsequent cutting. The cutting blade 11 of the secondary slitting roller 9 cuts along the deep groove, ensuring the precision and consistency of the cutting position and improving the dimensional accuracy and surface quality of the product.
[0039] This slitting equipment achieves efficient and precise cutting of aluminum sheets through the coordinated operation of the primary slitting mechanism 4 and the secondary slitting mechanism 5. The primary slitting mechanism 4 pre-forms deep grooves on the aluminum sheet, reducing the difficulty and required cutting force for subsequent cutting. The secondary slitting mechanism 5 cuts along these deep grooves, improving cutting speed and efficiency. The entire cutting process is continuous and smooth, suitable for the needs of large-scale aluminum sheet production.
[0040] The fixed connection between the first slot 12 and the cutting blade 11 ensures the stability of the cutting blade 11 during operation. The cutting blade 11 will not loosen or shift when rotating at high speed and bearing cutting force, guaranteeing the accuracy and consistency of the cut. At the same time, this fixed connection method also facilitates the installation and removal of the cutting blade 11, simplifying maintenance.
[0041] The slitting equipment has a reasonable structural design, with close cooperation between its components, and stable and reliable operation. The coordinated work of the primary slitting mechanism 4 and the secondary slitting mechanism 5, as well as the replaceable design of the cutting blade 11, make this equipment highly efficient, precise, and easy to maintain in aluminum plate production, meeting the high requirements of modern aluminum plate processing.
[0042] Example 5:
[0043] In this embodiment, the pressure strip 8 is a key component of the primary slitting mechanism 4. The pressure strips 8 are evenly distributed along the axial direction of the primary slitting roller shaft 6, and their number is consistent with that of the cutting blades 11 of the secondary slitting mechanism 5, both being 4. The main body of the pressure strip 8 is made of high-strength alloy steel, and a longitudinally extending second slot 13 is formed on its working surface. The cross-section of the second slot 13 is T-shaped, and the slot opening width is slightly smaller than the slot bottom width, forming a reliable mechanical locking structure.
[0044] The reinforcing member 14 is precision-machined from tungsten steel, and its cross-sectional shape perfectly matches the second slot 13. The installation process of the reinforcing member 14 is as follows: first, slide the reinforcing member 14 into the second slot 13 from the end of the pressure strip 8; after it is fully in place, secure it with the end fastening screws. The working surface of the reinforcing member 14 protrudes 0.5-1mm from the surface of the pressure strip 8, ensuring that it contacts the aluminum plate first during the cutting process.
[0045] During equipment operation, the primary slitting roller 6 drives the pressure strip 8 to rotate, and the tungsten carbide reinforcing member 14 applies pressure to the surface of the aluminum plate. Due to the extremely high hardness and wear resistance of tungsten carbide, it effectively resists friction and wear on the aluminum plate while maintaining stable indentation quality. When the reinforcing member 14 wears out due to long-term use, it can be quickly replaced simply by loosening the end fastening screws, without needing to disassemble the entire pressure strip 8.
[0046] This structural design offers several advantages: First, the tungsten carbide reinforcing member 14 directly bears the cutting pressure, protecting the main body of the pressure strip 8 from wear; second, the modular design makes maintenance and replacement more convenient; and third, reinforcing members 14 with different hardness can be flexibly selected according to the aluminum plate material, improving equipment adaptability. In actual production, this structure significantly extends the service life of the pressure strip 8 and reduces maintenance costs.
[0047] During the slitting process, the primary slitting mechanism 4 first presses neat, deep marks onto the aluminum plate surface using the reinforcing member 14. Subsequently, the cutting blade 11 of the secondary slitting mechanism 5 precisely cuts into these pre-pressed marks to complete the slitting. This step-by-step cutting method not only improves slitting efficiency but also ensures cut quality, preventing burrs or deformation from appearing on the aluminum plate edges. The entire slitting process is continuous and stable, making it suitable for mass production of aluminum plates.
