Description

Technical Field

[0001] This utility model relates to the field of carbon fiber paper material processing technology, specifically a carbon fiber paper molding device. Background Technology

[0002] Carbon fiber paper, a novel functional material made primarily from carbon fiber through a special process, boasts excellent mechanical properties (such as high strength and high modulus), good electrical and thermal conductivity, and outstanding high-temperature and corrosion resistance, demonstrating broad application prospects in numerous fields. To meet the specific requirements of different fields regarding the shape and performance of carbon fiber paper products, compression molding, as an efficient and stable processing method, is widely adopted.

[0003] Chinese Patent Publication No. CN115772826A discloses a carbon fiber paper basin forming device, belonging to the field of paper basin processing technology. This carbon fiber paper basin forming device includes a forming equipment. A pressing mold is provided on the rear side of the forming equipment. A placement groove is opened on the top of the forming equipment, and a forming mold is slidably connected inside the placement groove. A retaining groove is opened on the bottom of the forming mold, and limiting grooves are opened on both the left and right sides of the retaining groove. A fixing and disassembly device is provided in the placement groove. The fixing and disassembly device includes a retaining block. By moving the moving rod downwards, the limiting block can be effectively disengaged from the limiting groove, thereby allowing the forming mold to be more easily disengaged from the placement groove. This effectively improves the efficiency of mold replacement. Furthermore, by conveniently replacing the forming mold, the entire device can more easily complete the forming of carbon fiber paper basins of different depths, improving the applicability and versatility of the entire device and further enhancing the overall effect of carbon fiber paper basin production.

[0004] In the existing technology, the use of a carbon fiber paper basin molding device only emphasizes the ease of mold replacement and does not involve the precision structure related to pressure control. The pressure application may be a monolithic and undifferentiated mode, which is not convenient for accurately adjusting the pressure for the molding needs of different areas of the paper basin (such as the edge and bottom). This can easily lead to uneven local pressure, resulting in molding defects such as wrinkles and inconsistent thickness of the paper basin, which affects product quality. Therefore, we have made improvements to this and proposed a carbon fiber paper molding device. Utility Model Content

[0031] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -3, a carbon fiber paper molding device, comprising an upper carbon fiber paper mold 1 and a lower carbon fiber paper mold 3, with U-shaped plates 5 fixedly installed on corresponding sides of the lower carbon fiber paper mold 3, and hydraulic rods 22 provided on the top of the two U-shaped plates 5, the hydraulic rods 22 passing through the U-shaped plates 5 and fixedly connected to them, the output ends of the two U-shaped plates 5 being fixedly connected to the upper carbon fiber paper mold 1, a pressure plate 2 fixedly installed on the bottom of the upper carbon fiber paper mold 1, a memory block 4 slidably connected to the top of the lower carbon fiber paper mold 3, and multiple pressure units provided on the bottom of the pressure plate 2, each pressure unit consisting of an execution pressure head 6, a servo motor 7, a lead screw 8 and a pressure sensor, the servo motor 7 and the pressure sensor being fixedly connected to the pressure plate 2, the output end of the servo motor 7 being fixedly connected to the lead screw 8, the lead screw 8 being inserted into the interior of the execution pressure head 6 and threadedly connected to it, and multiple heating tubes 11 being provided inside the upper carbon fiber paper mold 1.

[0032] In this embodiment of the invention, the controller 23 controls the hydraulic rod 22 to extend, pushing the upper carbon fiber paper mold 1 downwards until the pressure plate 2 approaches the memory block 4 on the lower carbon fiber paper mold 3. At this time, the heating tube 11 starts working, heating the upper mold and surrounding area to provide the temperature required for carbon fiber paper forming.

[0033] When pressure needs to be applied to the carbon fiber paper, the controller 23 instructs the servo motor 7 to start. The servo motor 7 drives the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the pressure head 6, the rotation of the lead screw 8 is converted into the up and down movement of the pressure head 6, so that the pressure head 6 contacts and squeezes the carbon fiber paper. The pressure sensor monitors the pressure applied by the pressure head 6 in real time and feeds the data back to the controller 23. The controller 23 adjusts the operation of the servo motor 7 according to the preset parameters to ensure accurate pressure.

[0034] In this embodiment of the invention, multiple independent pressure units, in conjunction with the servo motor 7, lead screw 8, and pressure sensor, can apply precise pressure to different areas of the carbon fiber paper to meet the requirements of complex shape forming and improve the forming quality. The heating tube 11 provides a stable temperature environment and works in synergy with the pressure units to further enhance the forming effect and performance of the carbon fiber paper. The hydraulic rod 22 drives the upper mold to rise and fall, ensuring the stability and efficiency of the forming process.

[0035] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -5. As a preferred embodiment of the present invention, two non-contact infrared sensors 9 are embedded in the bottom of the carbon fiber paper mold 1, and contact thermocouples 10 are fixedly installed at the four corners of the bottom of the carbon fiber paper mold 1. An overflow groove 12 is opened on the top of the memory block 4.

[0036] A push plate 14 is slidably connected inside the carbon fiber paper lower mold 3. Guide rods 15 are fixedly installed on both sides inside the carbon fiber paper lower mold 3. Both guide rods 15 pass through the push plate 14 and are slidably connected to it. Multiple insertion rods 16 are fixedly installed on the top of the push plate 14. The multiple insertion rods 16 are inserted into the memory block 4 and are slidably connected to it. Multiple springs 17 are provided on the side of the carbon fiber paper lower mold 3 and the push plate 14 that are close to each other. Both ends of the multiple springs 17 are fixedly connected to the carbon fiber paper lower mold 3 and the push plate 14 respectively.

[0037] U-shaped mounting plates 18 are provided on both sides of the memory block 4. Both U-shaped mounting plates 18 are slidably connected to the carbon fiber paper lower mold 3. Multiple fixing rods 19 are fixedly installed on the side of the two U-shaped mounting plates 18 that are close to each other. The multiple fixing rods 19 are inserted into the memory block 4 and slidably connected to it. A rotating plate 20 is provided inside the two U-shaped mounting plates 18, and the rotating plate 20 is rotatably connected to the U-shaped mounting plate 18. Threaded rods 21 are fixedly installed on the side of the two rotating plates 20 that are far from each other. The threaded rods 21 pass through one side of the U-shaped mounting plate 18 and are rotatably connected to it. The two threaded rods 21 pass through both sides of the carbon fiber paper lower mold 3 and are threadedly connected to it.

[0038] Limiting blocks 13 are fixedly installed on both sides of the mold 1 on the carbon fiber paper. The two limiting blocks 13 are inserted into the interior of the two U-shaped plates 5 and slidably connected to them.

[0039] A controller 23 is embedded on one side of the carbon fiber paper mold 1. The controller 23 is electrically connected to multiple servo motors 7, pressure sensors, heating tubes 11 and two hydraulic rods 22.

[0040] In this embodiment of the invention, during the heating and molding process, the contact thermocouple 10 is in direct contact with the surface of the mold cavity to monitor the contact temperature between the mold and the carbon fiber paper in real time, while the non-contact infrared sensor 9 monitors the actual temperature of the carbon fiber paper surface from above. The data from both sensors are transmitted to the controller 23 and processed for precise control of the power of the heating tube 11.

[0041] When the molding is completed, the mold 1 on the carbon fiber paper is raised, and the push plate 14 moves upward under the elastic force of the spring 17. The guide rod 15 ensures that the push plate 14 moves smoothly, and the insertion rod 16 on the top of the push plate 14 moves upward accordingly, pushing the memory block 4 to reset upward, so as to facilitate the removal of the molded carbon fiber paper.

[0042] When installing memory block 4, rotate threaded rod 21. Threaded rod 21 drives rotating plate 20 to rotate, causing U-shaped mounting plate 18 to move towards memory block 4. Fixing rod 19 is inserted into memory block 4 to fix memory block 4. If memory block 4 needs to be replaced or adjusted, rotate threaded rod 21 in the opposite direction to loosen the fixation. The operation is convenient.

[0043] During the process of the hydraulic rod 22 driving the carbon fiber paper mold 1 to rise and fall, the limiting block 13 slides inside the U-shaped plate 5 to restrict the movement direction of the carbon fiber paper mold 1, prevent the upper mold from deviating, and ensure that the upper and lower molds are accurately aligned.

[0044] The controller 23 serves as the core of the entire device. It receives feedback signals from components such as pressure sensors, contact thermocouples 10, and non-contact infrared sensors 9. According to the preset program, it sends instructions to servo motors 7, heating tubes 11, hydraulic rods 22, etc., to achieve coordinated work of each component and ensure the automation and precision of the molding process.

[0045] In this embodiment of the utility model, the dual temperature monitoring of the contact thermocouple 10 and the non-contact infrared sensor 9 improves the accuracy of temperature detection, provides a basis for the precise temperature control of the heating tube 11, and ensures that the carbon fiber paper is cured evenly. When excess material overflows during the carbon fiber paper forming process, it will flow into the overflow groove 12 at the top of the memory block 4. The overflow groove 12 can effectively collect the overflow material, avoid material accumulation affecting the forming, and reduce subsequent cleaning work.

[0046] The cooperation of push plate 14, guide rod 15, insertion rod 16 and spring 17 realizes the automatic reset of memory block 4, which facilitates the removal of the molded product and improves work efficiency.

[0047] The design of the U-shaped mounting plate 18, fixing rod 19, rotating plate 20 and threaded rod 21 makes the installation, fixing and replacement of memory block 4 more convenient, can adapt to the molding requirements of carbon fiber paper of different specifications, and enhances the versatility of the device.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
