Detailed Implementation

[0015] 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.

[0016] Example 1:

[0017] This utility model provides a slitting and cutting device for aluminum plates, including a main frame 1, on which a workbench 2 is fixedly mounted. An upper frame 3 is also fixedly mounted on the main frame 1. A lifting frame 5 is movably mounted on the upper frame 3 via a slide rail 4. A drive cylinder 6 is fixedly mounted on the upper frame 3, driving and connecting the lifting frame 5. An optical axis 7 and a drive motor 8 are fixedly mounted on the lifting frame 5. A reciprocating frame 9 is movably mounted on the optical axis 7. An eccentric flywheel 10 is driven and connected to the drive motor 8. The eccentric flywheel 10 is driven and connected to the reciprocating frame 9 via a pull rod 11. An assembly plate 12 is fixedly mounted on the reciprocating frame 9, and multiple saw blades 13 are fixedly mounted on the assembly plate 12. The assembly plate 12 has an adjustment groove 14, which is fixedly connected to the saw blades 13 via fastening bolts 15. The fastening bolts 15 include a bolt head 16, a flat section 17, a bolt section 18, and a nut 19. The flat section 17 is inserted into and fixed to the adjustment groove 14, and the bolt section 18 is screwed into and fixed to the nut 19. Baffles 20 are symmetrically fixed on both sides of the workbench 2.

[0018] Through the above technical solution, the main frame 1 of this utility model is fixedly installed with an upper frame 3. The upper frame is movably installed with a lifting frame 5 via a slide rail 4. The driving cylinder 6 drives the lifting frame 5 to move up and down. The lifting frame 5 is movably installed with a reciprocating frame 9 via an optical axis 7. The reciprocating frame 9 is fixedly installed with a saw blade 13 via an assembly plate 12. During operation, the cylinder drives the lifting frame 5 to move downward, which is started by the driving motor 8, driving the eccentric flywheel 10 to rotate. The reciprocating frame 9 is driven to move repeatedly via the pull rod 11, so that the saw blade cuts the aluminum plate and quickly completes the aluminum plate slitting operation. The reciprocating frame 9 pulls the saw blade 13 back and forth to cut the aluminum plate, reducing the safety hazards in the aluminum plate processing process.

[0019] Example 2:

[0020] In this embodiment, the main frame 1 serves as the supporting structure for the entire device. It is welded from steel and possesses sufficient rigidity and stability. A worktable 2 is fixedly mounted at the bottom of the main frame 1. The worktable 2 has a flat surface and is used to place the aluminum plate to be cut. The worktable 2 is made of wear-resistant material and can withstand the friction and pressure during the aluminum plate cutting process.

[0021] An upper frame 3 is fixedly mounted on the upper part of the main frame 1. The upper frame 3 is bolted to the main frame 1 to form a stable frame structure. A slide rail 4 is provided on the inner side of the upper frame 3. The slide rail 4 uses a linear guide rail to ensure motion accuracy. The lifting frame 5 is installed in cooperation with the slide rail 4 via a slider, allowing it to slide up and down on the slide rail 4. A drive cylinder 6 is fixedly mounted on the top of the upper frame 3. The piston rod of the cylinder is connected to the lifting frame 5, and the lifting frame 5 is driven to move up and down along the slide rail 4 by air pressure.

[0022] The lifting frame 5 adopts a welded steel plate structure, with an internally fixed optical shaft 7. Both ends of the optical shaft 7 are fixed to the lifting frame 5 via bearing seats. The reciprocating frame 9 is mounted on the optical shaft 7 via linear bearings, allowing it to reciprocate horizontally along the optical shaft 7. A drive motor 8 is fixedly mounted on one side of the lifting frame 5, and the motor output shaft is connected to an eccentric flywheel 10 via a coupling. An eccentric shaft is mounted on the eccentric flywheel 10, and one end of the pull rod 11 is hinged to the eccentric shaft, while the other end is hinged to the reciprocating frame 9, forming a crank-connecting rod mechanism.

[0023] The reciprocating frame 9 is a welded steel plate structure with an assembly plate 12 fixedly mounted at its front end. The assembly plate 12 is made of aluminum alloy and is bolted to the reciprocating frame 9. Multiple mounting slots are provided on the assembly plate 12, and each saw blade 13 is fixed within one of these slots using a special clamp. The saw blades 13 are made of high-speed steel, possessing high hardness and wear resistance. The spacing between the saw blades 13 can be adjusted as needed to achieve slitting of aluminum plates of different widths.

[0024] During operation, the operator places and positions the aluminum plate on the workbench 2. The drive cylinder 6 is activated, pushing the lifting frame 5 downwards along the slide rail 4, bringing the saw blade 13 close to the aluminum plate surface. The drive motor 8 is activated, rotating the eccentric flywheel 10, which in turn drives the reciprocating frame 9 to perform horizontal reciprocating motion on the optical axis 7 via the pull rod 11. The saw blade 13 moves with the reciprocating frame 9, reciprocating to cut the aluminum plate. Because the saw blade 13 moves at a moderate speed, less heat is generated during the cutting process, avoiding the high-temperature problem of traditional rotary cutting blades. Simultaneously, the reciprocating cutting method reduces the impact force during the cutting process, minimizing the risk of blade breakage.

[0025] After cutting, the drive cylinder 6 raises the lifting frame 5, and the saw blade 13 leaves the aluminum plate surface. The operator can then remove the cut aluminum strip, completing the entire slitting process. This device achieves cutting through reciprocating motion, which is safer and more reliable than traditional rotary cutting methods, making it particularly suitable for large-volume aluminum plate slitting. The device has a simple structure, is easy to operate, and has low maintenance costs, making it widely applicable in the aluminum plate processing industry.

[0026] Example 3:

[0027] In this embodiment, the assembly plate 12 is provided with an adjustment groove 14, which is fixedly connected to the saw blade 13 by fastening bolts 15. The spacing of the saw blade 13 is adjusted by adjusting the adjustment groove 14, thereby controlling the width of the cut aluminum strip.

[0028] In the specific implementation process, the assembly plate 12 has multiple parallel adjustment grooves 14 along its length. Each adjustment groove 14 is elongated and extends laterally along the assembly plate 12. Each saw blade 13 has a mounting base at its mounting end, and the mounting base has mounting holes that match the adjustment grooves 14. Fastening bolts 15 pass through the mounting holes and are locked in the adjustment grooves 14, so that the saw blade 13 is stably fixed on the assembly plate 12. Since the length of the adjustment grooves 14 allows the saw blade 13 to move laterally within a certain range, the position of the saw blade 13 in the adjustment grooves 14 can be adjusted by loosening the fastening bolts 15, thereby changing the spacing between adjacent saw blades 13.

[0029] During adjustment, the operator can pre-measure and set the spacing of the saw blades 13 according to the required width of the aluminum strip. For example, if a 50mm wide aluminum strip needs to be cut, the spacing between adjacent saw blades 13 should be adjusted to 50mm. After adjustment, tighten the fastening bolts 15 to firmly fix the saw blades 13 onto the mounting plate 12, ensuring that no displacement occurs during cutting. Due to the relatively long length of the adjustment groove 14, the spacing adjustment range of the saw blades 13 is large, which can adapt to the slitting requirements of aluminum plates of different specifications.

[0030] During the cutting operation, the drive motor 8 drives the eccentric flywheel 10 to rotate, which in turn drives the reciprocating frame 9 to reciprocate along the optical axis 7 via the tie rod 11. This, in turn, drives the assembly plate 12 and the saw blade 13 to perform high-speed reciprocating cutting. Since the spacing of the saw blade 13 has been pre-adjusted, the cut aluminum strips are of uniform width, meeting different processing requirements. In addition, because the saw blade 13 uses reciprocating motion rather than high-speed rotation for cutting, it avoids the heat accumulation problem caused by the high-speed rotation of traditional cutting blades, reducing safety hazards during aluminum plate processing.

[0031] This embodiment achieves flexible adjustment of the saw blade spacing 13 through the cooperation of the adjusting groove 14 and the fastening bolt 15, enabling the slitting cutting device to adapt to the cutting needs of aluminum plates of different widths, thus improving the versatility and processing efficiency of the equipment. At the same time, the reciprocating cutting method effectively reduces processing risks and improves operational safety.

[0032] Example 4:

[0033] In this embodiment, the fastening bolt 15 consists of a bolt head 16, a flat section 17, a bolt section 18, and a nut 19. The flat section 17 is inserted into the adjustment groove 14 on the assembly plate 12, and the bolt section 18 passes through the mounting hole of the saw blade 13 and is tightened and fixed with the nut 19.

[0034] During assembly, the bolt head 16 is positioned outside the adjusting groove 14, acting as a limit to prevent the fastening bolt 15 from moving inwards as a whole. The cross-sectional shape of the flat section 17 matches the opening shape of the adjusting groove 14, typically being rectangular or elliptical, allowing it to fit tightly into the adjusting groove 14 and preventing the fastening bolt 15 from rotating during tightening. This design ensures that the bolt does not rotate when the nut 19 is tightened, thus guaranteeing the accurate and secure installation position of the saw blade 13.

[0035] After the bolt segment 18 passes through the mounting hole of the saw blade 13, it engages with the nut 19 and is tightened, clamping the saw blade 13 between the assembly plate 12 and the nut 19. Because the flat segment 17 restricts the rotation of the bolt, the operator only needs to rotate the nut 19 to complete the tightening, eliminating the need for additional fixing bolts and improving assembly efficiency. Simultaneously, the opening of the adjustment groove 14 allows the saw blade 13 to be adjusted within a certain range to accommodate the slitting requirements of aluminum plates of different widths.

[0036] During the cutting process, the drive motor 8 drives the eccentric flywheel 10 to rotate, which in turn drives the reciprocating frame 9 to reciprocate along the optical axis 7 via the pull rod 11, causing the saw blade 13 to cut the aluminum plate. Because the flat section 17 of the fastening bolt 15 fits tightly with the adjusting groove 14, the bolt is prevented from loosening or shifting, ensuring that the saw blade 13 remains stable during high-speed reciprocating motion, reducing vibration and shift, thereby improving cutting accuracy and safety.

[0037] The structural design of the fastening bolt 15 not only simplifies the installation and adjustment process of the saw blade 13, but also enhances the stability of the saw blade 13 during high-speed cutting, effectively reducing safety hazards caused by loose bolts and improving the efficiency and reliability of aluminum plate slitting.

[0038] Example 5:

[0039] In this embodiment, baffles 20 are symmetrically fixedly installed on both sides of the worktable 2. The baffles 20 are set perpendicular to the movement direction of the reciprocating frame 9, and their function is to prevent the aluminum plate from shifting or moving during the sawing process, ensuring cutting accuracy and stability. The baffles 20 are made of high-strength metal material and are fixed to the two side edges of the worktable 2 by bolts or welding, so that they can withstand the lateral forces that may be generated by the aluminum plate during the cutting process.

[0040] The baffle 20 is slightly higher than the surface of the worktable 2 to ensure that the aluminum plate is effectively restrained when placed, while avoiding interference with the up-and-down movement of the saw blade 13. The inner surface of the baffle 20 is smoothed to reduce frictional resistance with the aluminum plate and prevent damage to the aluminum plate during cutting. In addition, the length of the baffle 20 is matched to the cutting area of ​​the worktable 2 to ensure that the aluminum plate is always restrained when entering the cutting area, preventing the aluminum plate from deviating from the predetermined cutting path due to vibration or external forces.

[0041] During the cutting process, the aluminum plate is placed on the worktable 2 and pressed against the side baffles 20 to maintain its stability. When the drive cylinder 6 pushes the lifting frame 5 down, causing the saw blade 13 to contact the aluminum plate, the reciprocating frame 9, driven by the eccentric flywheel 10 and the pull rod 11, performs high-speed reciprocating motion, driving the saw blade 13 to cut the aluminum plate. Due to the presence of the baffles 20, the aluminum plate will not experience lateral displacement during the cutting process due to the reciprocating motion of the saw blade 13, thus ensuring the straightness and consistency of the cutting lines.

[0042] The baffle 20 not only improves cutting accuracy but also reduces the frequency of operators adjusting the position of the aluminum plate, thereby increasing production efficiency. Simultaneously, because the aluminum plate remains stable during cutting, the saw blade 13 experiences more uniform force, reducing the risk of breakage due to uneven force distribution and further enhancing the safety and lifespan of the equipment.

[0043] Furthermore, the structure of the baffle 20 can be adjusted to accommodate aluminum plates of different specifications. For example, by using an adjustable installation method or replacing the baffle 20 with one of different heights, it can adapt to the cutting needs of aluminum plates of different thicknesses or widths. This design enhances the versatility of the equipment, enabling it to adapt to diverse production requirements.

[0044] In summary, the baffle 20 effectively solves the stability problem of aluminum plates during the cutting process, improves cutting accuracy and safety, and enhances the adaptability and production efficiency of the equipment.
