Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a carbon fiber composite cutting device. Background Technology

[0002] Carbon fiber reinforced composites have been widely used in many fields due to their significant advantages such as high specific strength, high specific stiffness and designable properties.

[0003] Currently, composite material cutting technologies are mainly divided into mechanical cutting, laser cutting, water (abrasive) jet cutting, and electrical discharge cutting. However, these existing technologies all have certain limitations.

[0004] Considering factors such as production environment conditions, production costs, and cutting quality, mechanical cutting is a commonly used method. However, existing mechanical cutting equipment has many problems. For example, traditional cutting devices have poor stability during cutting. The equipment is prone to vibration during the cutting process, which not only affects cutting accuracy but also accelerates the wear of the cutting tools, reducing their lifespan. Furthermore, the debris generated during cutting is easily scattered, posing safety hazards to operators and potentially affecting the cleanliness of the work environment and the normal operation of the equipment. Moreover, existing mechanical cutting equipment often struggles to flexibly adjust the spacing of the cutting tools when cutting carbon fiber composites of different sizes, requiring the replacement of different molds or complex adjustments, resulting in low production efficiency.

[0005] In addition, the lifespan of the cutting tools is also a critical issue. Some ordinary carbide tools are prone to edge wear and chipping when cutting carbon fiber composites, resulting in a decline in cutting quality.

[0006] Therefore, in order to meet the increasingly widespread application needs of carbon fiber composite materials, improve cutting accuracy, production efficiency and equipment stability, and reduce production costs, there is an urgent need for a new type of carbon fiber composite material cutting device. Utility Model Content

[0007] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a carbon fiber composite cutting device. By optimizing the equipment structure, it aims to improve the cutting accuracy, production efficiency and stability of the cutting device, and has broad application prospects.

[0008] Technical solution: A carbon fiber composite cutting device, comprising: frame; A processing table, which is located at the center of the machine frame; Two baffles are symmetrically arranged on the machine frame, on the left and right sides outside the processing table; two sliding grooves are symmetrically opened on the machine frame, on the outer sides of the two baffles. A cutting mechanism includes a movable tool holder, a hydraulic cylinder, an adjusting component, and a cutting tool. The movable tool holder is a gantry structure, with its two lower ends respectively positioned within and slidably connected to a slide groove. The hydraulic cylinder is located at the top of the movable tool holder. The adjusting component is positioned below the movable tool holder, between two baffles, and the telescopic rod of the hydraulic cylinder passes through the movable tool holder and connects to the adjusting component. The cutting tool is mounted on the adjusting component. Vibration dampers are provided at the four corners of the bottom of the frame.

[0009] The carbon fiber composite cutting device of this utility model includes a frame, a processing table, baffles, a cutting mechanism, and a vibration damper. The frame serves as the supporting foundation for the entire device, providing a stable mounting platform for other components. The processing table is positioned in the center of the frame, facilitating the cutting of carbon fiber composites; this rational layout enhances operational convenience and efficiency. Two baffles, symmetrically arranged on the left and right sides of the processing table on the frame, serve to limit movement, shield, and prevent debris from splashing. This not only ensures operator safety, preventing injury from debris generated during cutting, but also maintains a clean working environment and minimizes disruption to normal equipment operation. The moving blade holder of the cutting mechanism is a gantry structure, with its two lower ends respectively positioned within and slidably connected to a slide groove. This allows the cutting mechanism to move flexibly on the frame, facilitating the cutting of carbon fiber composites at different locations and improving cutting flexibility and applicability. The extension and retraction of the hydraulic cylinder's telescopic rod controls the overall vertical movement of the adjustment assembly, thereby achieving vertical feed of the cutting blade and completing the cutting action. This precise control method improves cutting accuracy and ensures cutting quality. Vibration dampers installed at the four corners of the frame effectively reduce vibrations generated during cutting. Reduced vibration not only improves cutting accuracy but also reduces wear on the cutting tools, extending their lifespan, and enhancing the stability and reliability of the equipment.

[0010] Furthermore, in the aforementioned carbon fiber composite cutting device, the adjusting assembly includes a base, a screw, a rotating assembly, and a threaded connecting seat. The base is located below the movable tool holder, between two baffles, and the telescopic rod of the hydraulic cylinder passes through the movable tool holder and connects to the base. The screw is a bidirectional threaded rod, with its front end rotatably connected to the inner front wall of the base and its other end extending through the base to the outer rear side of the base and connecting to the rotating assembly. The outer wall of the screw is threadedly connected to a threaded sleeve, and the outer wall of the threaded sleeve is fixedly connected to a threaded connecting seat. A cutting tool is disposed at the bottom of the threaded connecting seat and connected to the cutting tool.

[0011] The screw in the adjusting assembly is a bidirectional threaded rod. By rotating the screw, the threaded sleeves on both sides move in opposite directions along the screw, thus adjusting the lateral spacing between the cutting blades. This allows the cutting device to flexibly adapt to the cutting needs of carbon fiber composites of different sizes without the need to change different molds or perform complex adjustments, greatly improving production efficiency. The cutting blade is located at the bottom of the threaded connector and connected to it, ensuring the stability of the cutting blade installation and preventing the blade from shaking or shifting during the cutting process, further improving cutting accuracy.

[0012] Furthermore, in the aforementioned carbon fiber composite cutting device, the rotating assembly includes a rotating handle, and the other end of the screw passes through the base and is connected to the rotating handle.

[0013] The rotating assembly includes a rotating handle, with the other end of the screw passing through the base and connected to the rotating handle. Operators can easily control the screw's rotation by turning the rotating handle, thereby adjusting the cutting tool spacing; operation is simple and convenient.

[0014] Furthermore, in the aforementioned carbon fiber composite cutting device, the rotating assembly further includes a limiting ring, a limiting plate, and an insert plate. The limiting ring is positioned between the base and the rotating handle and is fixedly connected to the screw. The limiting plate is fixedly connected to the rear outer wall of the base. An insert plate is slidably connected to the inner wall of the limiting plate, and the bottom end of the insert plate is inserted into the groove of the outer ring of the limiting ring.

[0015] The limiting ring, limiting plate, and insert plate in the rotating assembly work together. After the spacing of the cutting tools is adjusted, the bottom end of the insert plate is inserted into the groove of the outer ring of the limiting ring, which can limit the rotation of the screw, ensure the stability of the tool spacing during the cutting process, and guarantee the consistency of cutting accuracy.

[0016] Furthermore, in the aforementioned carbon fiber composite cutting device, three threaded connectors are provided, located on the front, middle, and rear sides of the screw respectively; the threaded connectors located on the front and rear sides are threadedly connected to both sides of the screw, and the threaded connector located in the middle is rotatably connected to the middle of the screw.

[0017] There are three threaded connectors, located at the front, middle, and rear of the screw. The front and rear connectors are threaded to the sides of the screw, while the middle connector is rotatably connected to the center of the screw. This design allows the cutting device to flexibly adjust the position and spacing of the blades according to different cutting needs, enabling diverse cutting methods and improving the versatility and applicability of the device.

[0018] Furthermore, in the aforementioned carbon fiber composite cutting device, the cutting tool includes a cemented carbide substrate and a multi-layer composite diamond coating disposed on the cemented carbide substrate; the multi-layer composite diamond coating includes, from the inside out, a micron-sized diamond coating, a gradient diamond coating, and a nano-sized diamond coating.

[0019] The cutting tool employs a cemented carbide substrate with a multi-layered composite diamond coating. The cemented carbide substrate possesses excellent toughness, hardness, and thermal stability, providing a solid foundation for the tool. The multi-layered composite diamond coating comprises micron-sized diamond coatings, gradient diamond coatings, and nano-sized diamond coatings from the inside out. This alternating, multi-layered composite diamond coating microstructure effectively enhances coating adhesion and crack propagation resistance, significantly improving the tool's wear resistance and reducing edge wear and chipping, thereby ensuring stable and consistent cutting quality. The diamond coating can be deposited onto tools of any complex shape using chemical deposition techniques (such as chemical vapor deposition), enabling the cutting tool to adapt to the cutting needs of various complex-shaped carbon fiber composites and expanding the application range of the device.

[0020] Furthermore, in the aforementioned carbon fiber composite cutting device, the vibration damper includes a vibration damping bracket, a mass block, vibration damping rubber I, vibration damping rubber II, a screw, a nut, a protective shell I, a protective shell II, and a washer; the vibration damping bracket, vibration damping rubber I, the mass block, and vibration damping rubber II are arranged sequentially from bottom to top; the screw passes through the vibration damping bracket, vibration damping rubber I, the mass block, and vibration damping rubber II, and a nut is provided above the screw; protective shell I is provided at the upper and lower ends of vibration damping rubber I; protective shell II is provided at the upper and lower ends of vibration damping rubber II; and a washer is provided at the connection between the screw and the vibration damping bracket.

[0021] The vibration damper has a symmetrical structure, consisting of a damping bracket, a mass block, a protective shell, bolts, nuts, and a pair of rubber units. The damping bracket connects and fixes the other components of the damper, while the protective shell provides support and protection for rubber units one and two, organically combining the pair of rubber units into a whole. The relative preload of the pair of rubber units can be controlled by adjusting the bolts and nuts. When subjected to external vibration excitation and with a certain preload, both the upper and lower rubber units are under pressure. Therefore, the damper can withstand cyclic tensile and compressive loads, achieving bidirectional vibration damping in the axial direction, effectively improving the stability and service life of the carbon fiber composite cutting device.

[0022] The beneficial effects of this utility model are as follows: The carbon fiber composite cutting device of this utility model is rationally designed. Its reasonable layout and movable cutting mechanism make operation more convenient and flexible, adapting to the cutting needs of carbon fiber composites in different positions and sizes. The baffle effectively prevents debris from flying, ensuring personnel safety and a clean working environment. Through the coordination of the adjusting and rotating components, the spacing of the cutting blades can be easily and accurately adjusted, achieving diverse cutting methods and greatly improving production efficiency and the device's versatility. The multi-layer composite diamond coating on the cutting blades improves their wear resistance and cutting quality, adapting to the cutting needs of complex shapes, reducing the frequency of blade replacement, and saving production costs. The vibration damper design effectively reduces vibration during the cutting process, improving cutting accuracy, extending the service life of the blades and equipment, and enhancing the stability and reliability of the equipment. By optimizing the equipment structure, the carbon fiber composite cutting device comprehensively improves cutting accuracy, production efficiency, and equipment stability, while reducing production costs, and has broad application prospects.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 , 2 Examples 3, 4, 5 and Example 1 further illustrate this utility model.

[0025] Example 1 like Figure 1-5 As shown, this embodiment 1 provides a carbon fiber composite cutting device, including a frame 1, a processing table 2, a baffle 3, a cutting mechanism, and a vibration damper 8, as detailed below: I. Installation and Preparation 1. Rack installation First, select a flat, solid ground as the installation base to ensure that the rack 1 is placed stably.

[0026] 2. Installation of processing table Place the processing table 2 accurately in the center of the frame 1. The processing table 2 can be securely connected to the frame 1 using locating pins or bolts to ensure it is firmly installed and will not shift during cutting. During installation, pay attention to the flatness of the processing table 2 surface to avoid affecting cutting accuracy due to unevenness.

[0027] 3. Baffle installation Two baffles 3 are symmetrically installed on the left and right sides of the processing table 2 on the frame 1. During installation, ensure the verticality and symmetry of the baffles 3, and fix them to the frame 1 using bolts or welding. The installation height and position of the baffles 3 should be adjusted according to actual cutting requirements to effectively limit movement, block debris, and prevent it from splashing.

[0028] 4. Installation of the cutting mechanism Installation of the movable tool holder 4: Install the two lower ends of the movable tool holder 4 into the two symmetrically opened slide grooves 11 on the frame 1, ensuring that the movable tool holder 41 can slide flexibly with the slide grooves 11. A suitable amount of lubricating oil can be applied to the slide grooves 11 to reduce friction and improve the smoothness of the sliding of the movable tool holder 4. The movable tool holder 4 can be moved to the designated position and then secured using fixing blocks to prevent movement during cutting.

[0029] Hydraulic cylinder 5 installation: Install hydraulic cylinder 5 on top of the movable tool holder 4, and use bolts to fix hydraulic cylinder 5 to the movable tool holder 4. During the connection process, pay attention to the installation direction and position of hydraulic cylinder 5 to ensure that its telescopic rod 51 can accurately pass through the movable tool holder 4 and connect to the adjustment component 6.

[0030] Installation of Adjustment Component 6: Install the adjustment component 6 below the movable tool holder 4, between the two baffles 3. Connect the movable tool holder 4 to the base 61 of the adjustment component 6 via the telescopic rod 51 of the hydraulic cylinder 5, ensuring a secure connection.

[0031] Installation of cutting tool 7: Install the cutting tool 7 at the bottom of the threaded connection seat 64 of the adjusting component 6, and use appropriate bolts or clamps to fix the cutting tool 7 to ensure the stability of the installation of the cutting tool 7 and avoid shaking or displacement during the cutting process.

[0032] The cutting tool 7 uses a cemented carbide matrix 71, which has good toughness, hardness, and thermal stability, providing a solid foundation for the tool. For example, the cemented carbide matrix formulation is: TiC 10-15%, Co 0.3-0.6%, Mo 0.3%-0.4%, Mn 0.8%-1.6%, Nb 0.3%-0.4%, Cr 1.0%-1.6%, Al 0.6%-1.0%, with the balance being WC.

[0033] The multi-layered composite diamond coating 72 comprises, from the inside out, a micron-sized diamond coating 721, a gradient diamond coating 722, and a nano-sized diamond coating 723. This alternating transitional microstructure of the composite multi-layered diamond coating effectively enhances coating adhesion and crack propagation resistance, thereby improving the wear resistance of the cutting tool. For example, a diamond coating can be deposited onto a cemented carbide substrate 71 using chemical deposition technology (such as chemical vapor deposition). The specific steps are as follows: 1. Substrate pretreatment: Before coating deposition, the cemented carbide substrate 71 needs to be pretreated to improve the adhesion between the coating and the cemented carbide substrate 71. Pretreatment includes cleaning and roughening steps. 2. Micron-sized diamond coating deposition: The pretreated cemented carbide substrate 71 is placed in a chemical vapor deposition apparatus, and a mixed gas containing a carbon source (such as methane) and hydrogen is introduced. Under certain temperature and pressure conditions, the carbon source decomposes and deposits on the substrate surface to form a micron-sized diamond coating. During the deposition process, parameters such as gas flow rate, temperature, and pressure need to be carefully controlled to ensure the quality and thickness uniformity of the micron-sized diamond coating. 3. Gradient Diamond Coating Deposition: After the micron-sized diamond coating is deposited, the gas composition and process parameters are gradually changed to deposit a gradient diamond coating. The composition and structure of the gradient diamond coating gradually change along the coating thickness direction, which can better bridge the performance differences between the micron-sized and nano-sized diamond coatings, improving the coating's adhesion and crack propagation resistance. Nano-Diamond Coating Deposition: Finally, a nano-diamond coating is deposited on the gradient diamond coating. The nano-diamond coating has higher hardness and wear resistance, which can further improve the cutting performance of the tool. Precise control of process parameters is also required when depositing the nano-diamond coating to obtain a high-quality coating.

[0034] 5. Vibration damper installation Install vibration dampers 8 at the four corners of the bottom of the frame 1. Securely connect the vibration damping brackets 81 of the vibration dampers 8 to the bottom of the frame 1. During installation, ensure the symmetry and stability of the vibration dampers 8 so that each vibration damper 8 can evenly bear the weight of the frame 1 and the vibration generated during the cutting process.

[0035] II. Debugging 1. Cutting mechanism debugging Adjusting the movable tool holder 4: Manually push the movable tool holder 4 to check its sliding within the slide groove 11. Observe whether the movable tool holder 4 can move smoothly and whether there is any jamming or stuckness. If the movement is not smooth, check whether there are foreign objects in the slide groove or whether the lubricating oil is evenly applied, and clean or add lubricating oil accordingly.

[0036] Hydraulic cylinder 5 debugging: Connect the hydraulic system of hydraulic cylinder 5, start the hydraulic pump, and control the extension rod 51 of hydraulic cylinder 5 to extend and retract. Observe whether the movement of extension rod 51 is smooth and whether the stroke meets the design requirements. By adjusting the pressure and flow parameters of the hydraulic system, ensure that hydraulic cylinder 5 can accurately control the overall up and down movement of adjustment component 6 to achieve vertical feed of cutting tool 7.

[0037] Adjustment component 6 debugging: Rotate the handle 631 to control the screw 62 to rotate. Observe whether the threaded sleeves on both sides can move towards or away from each other along the screw 62, thereby adjusting the lateral spacing between the cutting tools 7. Check whether the movement of the threaded sleeves is flexible and whether the spacing adjustment of the cutting tools 7 is accurate. During the debugging process, a measuring tool can be used to measure the spacing of the cutting tools 7 to ensure that it meets the cutting requirements. After adjusting the spacing of the cutting tools 7, insert the bottom end of the insert plate 634 into the groove of the outer ring of the limiting ring 632, and check whether the insert plate 634 can firmly restrict the rotation of the screw 62. Manually try to rotate the screw 62 to verify whether the limiting effect is good.

[0038] 2. Vibration damper adjustment Observe the operation of the vibration damper 8 while the cutting device is running unloaded. Detect the vibration of the frame 1 during the cutting process using vibration sensors and other equipment to evaluate the vibration damping effect of the vibration damper 8. If the vibration damping effect is found to be unsatisfactory, the relative preload of the pair of rubber components can be controlled by adjusting the bolts 85 and nuts 86 of the vibration damper 8 to achieve the best vibration damping effect.

[0039] III. Work Process 1. Material placement Place the carbon fiber composite material to be cut on the processing table 2, and adjust the position and orientation of the material according to the cutting requirements.

[0040] 2. Adjustment of cutting tool spacing Based on the dimensions and cutting requirements of the carbon fiber composite, rotate the handle 631 to control the screw 62 to rotate, adjusting the lateral spacing between the cutting blades 7. After adjustment, insert the bottom end of the insert plate 634 into the groove of the outer ring of the limiting ring 632 to fix the spacing of the cutting blades 7.

[0041] 3. Cutting operation The hydraulic system is activated, controlling the extension rod 51 of the hydraulic cylinder 5 to extend, causing the adjusting assembly 6 to move downwards, driving the cutting tool 7 to feed vertically and cut the carbon fiber composite. During the cutting process, the pressure and flow rate of the hydraulic system are adjusted in a timely manner according to the cutting situation to ensure a smooth and accurate cutting process.

[0042] 4. Monitoring the cutting process During the cutting process, closely observe the cutting situation, including cutting accuracy, cutting quality, and tool wear. If problems such as decreased cutting accuracy or severe tool wear are found, stop cutting immediately and make appropriate adjustments or replace the tool.

[0043] 5. Cleaning and maintenance After cutting, shut off the hydraulic system and clean the debris and waste from processing table 2. Regular maintenance of the cutting device is essential, including checking the secure connections of all components, ensuring lubrication is adequate, and replacing cutting tools as needed, to ensure the proper functioning and lifespan of the cutting device.

[0044] In summary, the carbon fiber composite material cutting device of this utility model fully leverages its advantages, improves cutting accuracy, production efficiency and equipment stability, reduces production costs, and meets the application requirements for cutting carbon fiber composite materials.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
