Description

Technical Field

[0001] This utility model relates to the field of CNC band saw technology, and in particular to a sealed noise reduction type CNC band saw. Background Technology

[0002] Enclosed noise-reducing CNC band saws, as an important branch of industrial cutting equipment, are mainly used for efficient and precise cutting of metal materials. Their core function lies in controlling the saw blade's movement trajectory through a CNC system, while simultaneously reducing noise pollution and ensuring operational safety through structural design. Traditional CNC band saws typically employ an open or semi-enclosed structure, relying on basic sound insulation measures (such as local soundproofing panels) to achieve noise reduction. Their key components include:

[0003] 1. Frame and transmission system: responsible for supporting the equipment and driving the saw blade, usually consisting of a metal frame, motor and gearbox;

[0004] 2. Sawing mechanism: includes saw blade, saw wheel and feed system, which directly performs the cutting task;

[0005] 3. Control system: Precise control of cutting parameters is achieved through a numerical control unit (CNC);

[0006] 4. Auxiliary devices: such as coolant systems and clamps, used to improve cutting quality and stability.

[0007] Currently, mainstream CNC band saws on the market achieve noise reduction and sealing in the following ways: some manufacturers use independent soundproof covers: the sawing area is wrapped by a detachable metal cover, but additional support is required for fixation, the structure is loose and the sealing effect is limited; some manufacturers use embedded sealing design: the sound insulation material is integrated into the equipment shell, but the material selection is limited (such as ordinary rubber strips), and it is prone to aging and failure after long-term use.

[0008] However, the above-mentioned technical solutions still have the following problems: the open structure cannot completely block high-frequency noise, resulting in serious noise pollution during the cutting process, which can easily cause occupational health hazards to operators. The fully enclosed structure needs to be fixed by bolts or welding, and the whole structure needs to be disassembled during maintenance, which is time-consuming and labor-intensive. Moreover, the modularity is low and it cannot flexibly adapt to different working conditions. In response to the above problems, this application proposes a new type of sealed noise-reducing CNC band saw. Through the design of a fully enclosed sealing cover, the application of composite sound insulation materials, and a convenient installation and connection structure, it achieves the goals of efficient noise reduction, reliable sealing, and rapid maintenance. The equipment greatly simplifies the installation process by optimizing the sealing cover limit connection method. At the same time, it uses multi-layer sound insulation composite materials to improve noise reduction performance, effectively solving the problems of serious noise pollution, high maintenance costs, and sealing failure in the existing technology. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this utility model provides a sealed noise-reducing CNC band saw, which solves the problems of open structures being unable to completely block high-frequency noise, resulting in serious noise pollution during cutting and posing occupational health hazards to operators, while fully enclosed structures require bolts or welding for fixation and require complete disassembly for maintenance, which is time-consuming and labor-intensive.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A sealed noise-reducing CNC band saw includes a band saw body and a worktable. Two fixed frames are arranged above the worktable. Sound insulation panels are fixedly connected to the upper surfaces of the two fixed frames. Two sealing plates for sealing are arranged behind the sound insulation panels. A sealing layer for noise reduction is fixedly connected to the opposite surfaces of the two fixed frames. A connecting strip is fixedly connected to the front surface of the fixed frame located in front of the two fixed frames. A screw is rotatably connected inside the connecting strip. Two limiting posts are movably sleeved inside the connecting strip. A sound insulation layer is fixedly connected to the lower surface of the sound insulation panel.

[0012] Preferably, each of the two fixed frames has two limiting blocks fixedly connected to its back side, the two limiting blocks are movably connected to the two sealing plates respectively, and the two limiting posts are movably sleeved with the two sealing plates respectively.

[0013] Preferably, each of the two limiting posts has two locking blocks fixedly connected to its annular side, and both limiting posts are threadedly connected to the screw. The connecting strip has two pairs of slots on its annular side, and the two pairs of slots are movably connected to the two pairs of locking blocks respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A sealing layer is installed between the two fixed frames to absorb and reduce noise. Together with the sound insulation layer under the sound insulation board and the two sealing boards, they form a sealed space that can effectively block the noise generated during the operation of the saw from spreading outward. The whole is made of transparent material, which makes it easy to observe the internal processing. In addition, sealant is filled between the two fixed frames and the sound insulation board to ensure the overall sealing performance. Overall, it can effectively improve the working environment and reduce the harm of noise to operators.

[0016] 2. When in use, push the two sealing plates forward until they reach the top. At this time, by turning the screw, the two limiting posts fitted on them will move in opposite directions due to the thread action. During the movement of the two limiting posts in opposite directions, they will engage with the two sealing plates, and the two sealing plates will be in a limited and fixed state. The overall operation is simple and convenient, which improves the efficiency and accuracy of the installation process. Attached Figure Description

[0023] This application provides a sealed noise-reducing CNC band saw, which effectively solves the problems of open structures failing to completely block high-frequency noise, resulting in severe noise pollution during cutting and posing occupational health hazards to operators. It also addresses the issue that fully enclosed structures require bolts or welding for fixing and overall disassembly for maintenance, which is time-consuming and labor-intensive. Through a fully enclosed sealing cover design, the application of composite sound insulation materials, and a convenient installation and connection structure, the device achieves efficient noise reduction, reliable sealing, and rapid maintenance. The optimized sealing cover limiting connection method significantly simplifies the installation process, while the use of multi-layered sound insulation composite materials enhances noise reduction performance, effectively solving problems such as severe noise pollution, high maintenance costs, and sealing failure in existing technologies. Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems that open structures cannot completely block high-frequency noise, resulting in serious noise pollution during the cutting process and posing occupational health hazards to operators, while fully enclosed structures require bolts or welding for fixation and need to be completely disassembled for maintenance, which is time-consuming and labor-intensive. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a sealed noise-reducing CNC band saw, including a band saw body 1 and a worktable 2. Two fixed frames 5 are arranged above the worktable 2. Sound insulation plates 4 are fixedly connected to the upper surfaces of the two fixed frames 5. Two sealing plates 3 for sealing are arranged behind the sound insulation plates 4. Noise-reducing sealing layers 10 are fixedly connected to the opposite surfaces of the two fixed frames 5. A connecting strip 6 is fixedly connected to the front surface of the front fixed frame 5. A screw 8 is rotatably connected inside the connecting strip 6, and the connecting strip 6 is movably sleeved within it. There are two limiting posts 12, and a sound insulation layer 9 is fixedly connected to the lower surface of the sound insulation plate 4. A sealing layer 10 is set between the two fixing frames 5 to absorb and reduce noise. Together with the sound insulation layer 9 set below the sound insulation plate 4 and the two sealing plates 3, a sealed space is formed, which can effectively block the noise generated during the operation of the saw from spreading outward. The whole is made of transparent material, which makes it easy to observe the internal processing. In addition, sealant is filled between the two fixing frames 5 and the sound insulation plate 4 to ensure the overall sealing performance. The whole can effectively improve the working environment and reduce the harm of noise to the operator.

[0026] Two limiting blocks 7 are fixedly connected to the back of each of the two fixed brackets 5. The two limiting blocks 7 are movably connected to the two sealing plates 3 respectively. The two limiting posts 12 are movably sleeved with the two sealing plates 3 respectively. Two locking blocks 13 are fixedly connected to the annular side of each of the two limiting posts 12. The two limiting posts 12 are threadedly sleeved with the screw 8. The annular side of the connecting strip 6 has two pairs of slots 11. The two pairs of slots 11 are movably connected to the two pairs of locking blocks 13 respectively. In use, push the two sealing plates 3 forward until they reach the top. At this time, by turning the screw 8, the two limiting posts 12 sleeved on it will move in opposite directions due to the thread action. During the opposite movement of the two limiting posts 12, they will sleeve with the two sealing plates 3. The two sealing plates 3 are in a limited and fixed state. The overall operation is simple and convenient, which improves the efficiency and accuracy of the installation process.

[0027] Among them, the band saw body 1 is the core body of the CNC band saw, which is used to support and install various components. Under the action of the motor and transmission system, it drives the saw blade to complete the cutting task of metal materials.

[0028] Workbench 2: Located above the band saw body 1, it is used to support the material to be cut, provide a stable working plane for cutting, and ensure that the cutting process is carried out smoothly;

[0029] Sealing plate 3: It works with fixing frame 5, sound insulation plate 4, etc. to form a sealed space, block noise, and can also work with limiting post 12, etc. during installation to achieve fixing and sealing functions;

[0030] Sound insulation panel 4: fixed on the mounting frame 5, and the sound insulation layer 9 below it works together to effectively block noise from spreading outward and reduce noise pollution in the work area;

[0031] Fixing frame 5: used to support components such as sound insulation board 4 and sealing board 3. The sealing layer 10 on the opposite surface can reduce noise. It also realizes the installation and fixing of sealing board 3 through structures such as connecting strip 6.

[0032] Connecting strip 6: Connected to the front fixed frame 5, internally rotating connecting screw 8 and movable sleeve limiting post 12, providing installation position for screw 8 and limiting post 12, and assisting in the installation of sealing plate 3;

[0033] Limiting block 7: Fixed on the back of the fixing frame 5, movably connected to the sealing plate 3, restricting the movement direction of the sealing plate 3, so that the sealing plate 3 remains stable during installation and use;

[0034] Screw 8: Rotates within the connecting strip 6, causing the limiting post 12 to move in opposite directions through the thread action, thereby engaging with the sealing plate 3 and achieving the limiting and fixing of the sealing plate 3;

[0035] Sound insulation layer 9: Fixed to the lower surface of sound insulation board 4, it works together with sound insulation board 4 to absorb and block the noise generated by the sawing machine, reducing the harm of noise to the operator;

[0036] Sealing layer 10: Fixed to the opposite side of the fixing frame 5, used to absorb and reduce noise, and in conjunction with other sealing structures, enhances the noise reduction and sealing effect of the entire equipment;

[0037] Slot 11: It is opened on the annular side of the connecting strip 6 and is movably connected to the locking block 13 on the limiting post 12. When the limiting post 12 moves, it plays a guiding and positioning role to ensure that the sealing plate 3 is installed accurately.

[0038] Limiting post 12: It moves within the connecting strip 6 and is threadedly connected to the screw 8 and movably connected to the sealing plate 3 to limit and fix the sealing plate 3, ensuring the stable installation of the sealing plate 3;

[0039] Block 13: Fixed to the annular side of the limiting post 12, it cooperates with the slot 11 on the connecting strip 6 to prevent the limiting post 12 from rotating during movement, ensuring its linear movement and accurately limiting the sealing plate 3.

[0040] Working principle:

[0041] A sealing layer 10 is provided between the two fixed frames 5 to absorb and reduce noise. Together with the sound insulation layer 9 below the sound insulation plate 4 and the two sealing plates 3, they form a sealed space that can effectively block the noise generated during the operation of the saw from spreading outward. The whole is made of transparent material, which makes it easy to observe the internal processing. Sealant is filled between the two fixed frames 5 and the sound insulation plate 4 to ensure the overall sealing performance. The whole can effectively improve the working environment and reduce the harm of noise to the operator. When in use, push the two sealing plates 3 forward to the top. At this time, by turning the screw 8, the two limiting posts 12 sleeved on it will move in opposite directions due to the thread action. During the movement of the two limiting posts 12 in opposite directions, they will engage with the two sealing plates 3. The two sealing plates 3 are in a limited and fixed state. The whole operation is simple and convenient to use, which improves the efficiency and accuracy of the installation process.
