Description

Technical Field

[0001] The present invention relates to the technical field of sound barrier forming, and particularly to a forming device for a carbon fiber composite sound barrier. Background Art

[0002] A forming device for a carbon fiber composite sound barrier is a device used to manufacture a carbon fiber composite sound barrier. Usually, a hot press is used to compound a carbon fiber reinforcing material with a matrix material such as resin, and under certain conditions such as temperature and pressure, the material is cured and formed into a sound barrier structure with a specific shape and performance.

[0003] However, when manufacturing a carbon fiber composite sound barrier by hot pressing, it usually includes multiple steps such as feeding, mold closing, pressurizing, pressure holding, cooling, and demolding. Each step requires a certain amount of time to complete. Especially during the cooling and demolding processes, it is necessary to wait for the product to cool to a certain temperature before performing the demolding operation. During this period, the equipment cannot perform the next forming operation, resulting in intermittency in the production process.

[0004] Moreover, the existing vacuum hot pressing process usually requires a long production cycle, including multiple links such as mold preparation, material layering, vacuum treatment, heating and pressurizing curing, and cooling and demolding. Each link requires strict control of time and parameters, resulting in relatively low production efficiency and being difficult to meet the requirements of large-scale production.

[0005] Therefore, a forming device for a carbon fiber composite sound barrier is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a forming device for a carbon fiber composite sound barrier to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A forming device for a carbon fiber composite sound barrier, including a working base and a first support column. The first support column is fixedly connected to the top surface of the working base. The lower surface of the top end of the first support column is provided with an upper mold. An auxiliary component is arranged on the working base. The auxiliary component includes a hydraulic motor. The hydraulic motor is fixedly connected to the top surface of the working base. The output end of the hydraulic motor faces upward. A cross link is fixedly connected to the output end of the hydraulic motor. Four turntables are fixedly connected to the top surface of the cross link in a circular array. A circular track is fixedly connected to the top surface of the working base. Each of the top surfaces of the four turntables is provided with a lower mold. A plurality of hydraulic rods are fixedly connected to the bottom surface of the inner wall of each of the four lower molds. The output ends of the hydraulic rods face upward. The output ends of the plurality of hydraulic rods inside the same lower mold are commonly fixedly connected to a lifting plate. A second support column is fixedly connected to the top surface of the working base. The top end of the second support column faces one side of the turntable.

[0008] Further, a triangular positioning rod is fixedly connected to the top end of the second support column, a third support column is fixedly connected to the top surface of the working base table, a support rod is fixedly connected to the side of the top end of the third support column away from the turntable, a servo motor is fixedly arranged on the support rod, a reciprocating lead screw is rotatably connected to the top end of the third support column, a guide rod is fixedly connected to the top end of the third support column, a moving table is slidably connected to the guide rod, a slider is rotatably connected to the moving table, a scraper is fixedly connected to the bottom end of the moving table, a collecting box is detachably connected to the outer wall of one side of each of the four lower molds close to the hydraulic motor by bolts, a fourth support column is fixedly connected to the top surface of the working base table, the top end of the fourth support column faces the turntable side, an electric telescopic tube is fixedly connected to the bottom surface of the top end of the fourth support column, the telescopic end of the electric telescopic tube faces downward, a square nozzle is fixedly connected to the telescopic end of the electric telescopic tube, and a corrugated tube is arranged inside the electric telescopic tube.

[0009] Further, all four turntables are slidably connected to the annular track.

[0010] Further, the hydraulic rod is driven and controlled by an external controller, the hydraulic rod is arranged in a multi-section manner, and the lifting plate is slidably adapted and tightly fitted with the inner wall of the lower mold.

[0011] Further, the bottom surface of the triangular positioning rod is attached to the top surface of the lower mold.

[0012] Further, the side of the scraper away from the support rod is provided as an inclined surface.

[0013] Further, the slider is slidably connected to the thread groove on the reciprocating lead screw.

[0014] Further, the electric telescopic tube is arranged in a multi-section hollow manner, a plurality of spray holes are uniformly formed in the side wall and the bottom surface of the square nozzle, the bottom end of the corrugated tube is fixedly communicated with the square nozzle, and the top end of the corrugated tube passes through the top surface of the fourth support column.

[0015] Further, there is an electrical connection relationship between the servo motor and the electric telescopic tube and the external controller.

[0016] Compared with the prior art, the beneficial effects of the present invention are: By dividing the production and molding of the carbon fiber composite material sound barrier into four consecutive working stations operating simultaneously, and the four working stations do not interfere with each other during operation, it solves the problem that in the traditional hot pressing process, the equipment is idle during steps such as cooling and demolding. Here, four working stations operate simultaneously. When one working station is performing cooling and demolding, other working stations can perform operations such as processing, removing residues, spraying release agents, and feeding materials. The equipment utilization rate is greatly improved, and there is no obvious intermittency in the production process, so that more carbon fiber composite material sound barriers can be produced per unit time.

[0017] Through the operation of the hydraulic rod and the lifting plate, the carbon fiber composite sound barrier can be quickly ejected from the lower mold after cooling is completed, without waiting for natural cooling and then manually or with the help of other complex tools for demoulding as in the traditional method. This greatly shortens the demoulding time, improves production efficiency, and after the sound barrier is ejected, a complete plane is formed at its bottom, and the user only needs to translate the sound barrier to achieve demoulding. The operation is simple and convenient, reducing the cumbersome steps in the demoulding process and further improving the demoulding efficiency.

[0018] The corner blocks of the triangular positioning rod can play a guiding role during the upward movement of the sound barrier, effectively preventing it from tilting or the corners from being damaged, ensuring the integrity and appearance quality of the sound barrier, reducing the rejection rate of the sound barrier caused by improper demoulding, and improving the yield rate of the sound barrier.

[0019] When the lifting plate is lifted, the residues on the side wall of the inner cavity of the lower mold are scraped to the top, and the residues on the complete plane formed by the lifting plate and the lower mold are cleaned by the scraping plate. There is no need to manually clean the inside of the lower forming mold, effectively avoiding the accumulation of residues in the mold, ensuring the integrity of the residue removal work, and at the same time solving the problem that the corner areas in the lower forming mold are difficult to handle in the prior art.

[0022] Embodiments provided by the present invention: Please refer to Figures 1 to 8 As shown in the figure, a forming device for a carbon fiber composite material sound barrier includes a working base 11 and a first support column 12. The first support column 12 is fixedly connected to the top surface of the working base 11. The first support column 12 is in an inverted L shape. The lower surface of the top end of the first support column 12 is provided with an upper die 13. A component for processing the sound barrier 14 is arranged on the working base 11.

[0023] Among them: a hydraulic device is arranged on the upper die 13, and the hydraulic device is used to provide a downward pressure to the upper die 13.

[0024] Among them: the sound barrier 14 is made of carbon fiber composite material as the raw material herein.

[0025] An auxiliary component is arranged on the working base 11. The auxiliary component includes a hydraulic motor 21. The hydraulic motor 21 is fixedly connected to the top surface of the working base 11. The output end of the hydraulic motor 21 faces upward. A cross connecting rod 22 is fixedly connected to the output end of the hydraulic motor 21. Four turntables 23 are fixedly connected to the top surface of the cross connecting rod 22 in a circumferential array. A ring track 24 is fixedly connected to the top surface of the working base 11. A lower die 25 is installed on the top surface of each of the four turntables 23. A plurality of hydraulic rods 26 are fixedly connected to the bottom surface of the inner wall of each of the four lower dies 25. The output ends of the hydraulic rods 26 face upward. The output ends of the plurality of hydraulic rods 26 inside the same lower die 25 are commonly fixedly connected to a lifting plate 27.

[0026] On the top surface of the working base 11, there is a fixedly connected second support column 28. The top end of the second support column 28 faces the side of the turntable 23. At the top end of the second support column 28, there is a fixedly connected triangular positioning rod 29. On the top surface of the working base 11, there is a fixedly connected third support column 210. On the side of the top end of the third support column 210 away from the turntable 23, there is a fixedly connected support rod 211. On the support rod 211, there is a fixedly arranged servo motor 212. The top end of the third support column 210 is rotatably connected with a reciprocating lead screw 213. The top end of the third support column 210 is fixedly connected with a guide rod 214. The reciprocating lead screw 213 and the guide rod 214 have the same orientation. A moving table 215 is slidably connected to the guide rod 214. A slider 216 is rotatably connected to the moving table 215. The slider 216 is slidably connected to the thread groove on the reciprocating lead screw 213. At the bottom end of the moving table 215, there is a fixedly connected scraper 217. On the outer wall of one side of each of the four lower molds 25 close to the hydraulic motor 21, there is a collection box 218 detachably connected by bolts. On the top surface of the working base 11, there is a fixedly connected fourth support column 219. The top end of the fourth support column 219 faces the side of the turntable 23. At the bottom surface of the top end of the fourth support column 219, there is a fixedly connected electric telescopic tube 220. The telescopic end of the electric telescopic tube 220 faces downward. The telescopic end of the electric telescopic tube 220 is fixedly connected with a square nozzle 221. Inside the electric telescopic tube 220, there is a corrugated tube 222.

[0027] Among them: All four turntables 23 are slidably connected to the annular track 24.

[0028] Specifically: Refer to Figure 1 As shown, taking the counterclockwise order as a reference, starting from the turntable 23 directly below the upper mold 13, the four turntables 23 respectively correspond to the processing station, the cooling and demolding station, the residue removal station, and the spraying and feeding station of the sound barrier 14 in the counterclockwise order.

[0029] It should be noted that: Hereinafter, the processing station, the cooling and demolding station, the residue removal station, and the spraying and feeding station are used to refer to the four turntables 23 at the four positions and the structures arranged above the turntable 23 after it reaches the predetermined position.

[0030] More specifically: The above settings of the four stations are to split the process of forming the sound barrier 14, realizing multi-station processing of the sound barrier 14.

[0031] Among them: The hydraulic rod 26 is driven and controlled by an external controller. The hydraulic rod 26 is of a multi-section type. The lifting plate 27 is slidably adapted and tightly fitted with the inner wall of the lower mold 25. And the lifting plate 27 is used as the forming bottom plate of the lower mold 25. When the hydraulic rod 26 is fully extended, the top surface of the lifting plate 27 is flush with the top surface of the lower mold 25. The function is: facilitating the demolding of the sound barrier 14 and at the same time facilitating the cleaning of the lower mold 25 and the lifting plate 27.

[0032] Among them: Refer to Figure 2As shown in the figure, the triangular positioning rod 29 is divided into three corner blocks and two connecting plates. The three corner blocks are respectively arranged at the three corners of the top surface of the lower mold 25 when the turntable 23 moves to the position of the triangular positioning rod 29. The connecting plates are connected between two adjacent corner blocks. The inner surface of the corner block corresponds to the inner surface side wall of the lower mold 25. That is, the three corner blocks play a role in corner positioning when the sound barrier 14 is demolded upward. Specifically: The triangular positioning rod 29 is integrally arranged in an L shape, that is, the triangular positioning rod 29 only occupies two sides of the four sides of the top surface of the lower mold 25, and the two sides not occupied by the triangular positioning rod 29 form gaps. The user can take away the demolded sound barrier 14 through these gaps. And the bottom surface of the triangular positioning rod 29 fits with the top surface of the lower mold 25 but is not fixedly connected to it, that is, the triangular positioning rod 29 will not affect the normal switching rotation of the four turntables 23 driving the lower mold 25.

[0033] Among them: Refer to Figures 4 to 6 As shown in the figure, the scraping plate 217 abuts and fits against the top surface of the lower mold 25 and the top surface of the lifting plate 27 flush with the top surface of the lower mold 25. And the side of the scraping plate 217 away from the support rod 211 is set as an inclined surface. That is, when the scraping plate 217 moves downward to the lower mold 25, the bottom surface of the scraping plate 217 can fit with the top surface of the lower mold 25 and the top surface of the lifting plate 27 flush with the top surface of the lower mold 25, and scrape the residual substances on the top surface of the lower mold 25 and the top surface of the lifting plate 27 flush with the top surface of the lower mold 25 towards the collecting box 218.

[0034] Among them: Refer to Figure 6 As shown in the figure, the slider 216 is slidably connected to the thread groove on the reciprocating lead screw 213. Therefore, the reciprocating lead screw 213 and the slider 216 form a ball screw structure. Under the sliding limit action of the guide rod 214, the moving table 215 drives the scraping plate 217 to horizontally reciprocate along the outer wall of the guide rod 214.

[0035] Among them: Refer to Figure 8 As shown in the figure, the electric telescopic tube 220 is multi-section and hollow inside. A plurality of spray holes are uniformly opened on the side wall and the bottom surface of the square spray head 221. The bottom end of the corrugated pipe 222 is fixedly communicated with the square spray head 221. The top end of the corrugated pipe 222 passes through the top surface of the support column four 219, and the top end of the corrugated pipe 222 can be externally connected to a demoulding agent supply device.

[0036] It should be noted that: The hydraulic rods 26 inside the four lower molds 25 can be independently controlled to extend and contract by an external controller, that is, the user can freely control the position of the lifting plates 27 inside the four lower molds 25 through the external controller. There is an electrical connection relationship between the servo motor 212 and the electric telescopic tube 220 and the external controller.

[0037] In the initial state of the auxiliary component, that is, when the sound barrier 14 is not being formed, at this time, the moving table 215 is located at one end of the reciprocating lead screw 213 close to the support column three 210, and the output end of the electric telescopic tube 220 contracts.

[0038] When the auxiliary component is running, that is, when the sound barrier 14 needs to be produced and formed, at this time, the output end of the hydraulic rod 26 at the processing station contracts directly below the upper die 13. There is a raw material of carbon fiber composite material stacked on the top of the lifting plate 27 at the processing station. The hydraulic device of the upper die 13 presses the bottom end of the upper die 13 into the inside of the lower die 25, so that the raw material inside the lower die 25 is hot-pressed and formed.

[0039] The following refers to Figure 1 And Figure 2 As shown, the cooling and demolding station is the next process station after the processing station produces and forms the sound barrier 14, that is, Figure 1 the station located in the lower left in . After the sound barrier 14 is hot-pressed and formed, the hydraulic device of the upper die 13 contracts, so that the upper die 13 no longer presses the sound barrier 14, and the upper die 13 is no longer located in the cavity of the lower die 25. At this time, the user drives the output end of the hydraulic motor 21 to rotate counterclockwise through the controller, and switches the turntable 23 at the processing station and the structures arranged on the turntable 23 to the cooling and demolding station.

[0040] The hydraulic rod 26 located at the cooling and demolding station maintains the state that the telescopic shaft contracts, that is, the position of the lifting plate 27 inside the lower die 25 remains unchanged. The function is to ensure that the position of the sound barrier 14 switched to the cooling and demolding station inside the lower die 25 remains unchanged, that is, the sound barrier 14 is statically cooled in the lower die 25 during the cooling process to avoid damage to the sound barrier 14 that is not fully cooled. When the sound barrier 14 located at the cooling and demolding station needs to be demolded after cooling, at this time, the user controls the telescopic end of the hydraulic rod 26 to fully extend through the controller, so that the hydraulic rod 26 pushes the top surface of the lifting plate 27 to be flush with the top surface of the lower die 25. At this time, the lifting plate 27 drives the cooled sound barrier 14 to move up synchronously inside the cavity of the lower die 25. Furthermore, the sound barrier 14 is pushed by the lifting plate 27 to rise outside the cavity of the lower die 25. During this process, the triangular positioning rod 29 provides the functions of guiding and corner positioning for the sound barrier 14, that is, during the rising process of the sound barrier 14, the corners inside the corner blocks of the triangular positioning rod 29 are in contact, avoiding the situation of skew or corner damage during the rising process of the sound barrier 14. When the sound barrier 14 is completely removed from the cavity of the lower die 25, at this time, the user takes away the sound barrier 14 from the gap formed by the triangular positioning rod 29 on the top surface of the lower die 25. It should be noted that: at this time, the sound barrier 14 has been pushed out of the cavity of the lower die 25 by the lifting plate 27, and at this time, the top surfaces of the lower die 25 and the lifting plate 27 are flush, and the top surfaces of the lower die 25 and the lifting plate 27 form a plane. The user can take away the sound barrier 14 from the gap of the triangular positioning rod 29 on this plane. Compared with the prior art, the user needs to take out the sound barrier 14 that fits the mold from the concave lower forming mold. Here, only translation is required to realize demolding and taking away the sound barrier 14, and the operation process is simpler. At the same time, it can avoid the problem that the sound barrier 14 that fits the mold is easily damaged when taken out manually.

[0041] When the demoulding of the sound barrier 14 at the cooling and demoulding station is completed, the user drives the output shaft of the hydraulic motor 21 to rotate through the controller, so that the hydraulic motor 21 drives the four turntables 23 to switch positions through the cross link 22. At this time, the turntable 23 slides on the annular track 24. It should be noted that when the turntable 23 at the processing station and the structures arranged on the turntable 23 are switched to the cooling and demoulding station in the above text, since the four turntables 23 are all connected to the cross link 22, that is, when the turntable 23 switches once, all four stations will switch and rotate to the next process station. That is, at this time, the user drives the rotation of the hydraulic motor 21 through the controller, which is the same operation as that in the above text. This description is added here for easy understanding.

[0042] The following refers to Figures 3 to 6 As shown, the turntable 23 switches from the cooling and demoulding station to the residue removal station, that is, Figure 1 the station in the lower right of [], at this time, the telescopic end of the hydraulic rod 26 remains in a fully extended state, that is, the top surface of the lifting plate 27 is flush with the top surface of the lower die 25. At this time, the user drives the output shaft of the servo motor 212 to rotate through the controller. The output shaft of the servo motor 212 drives the reciprocating lead screw 213 to rotate synchronously. While the reciprocating lead screw 213 rotates, it drives the moving table 215 to move horizontally along the guide rod 214, and the scraper 217 also moves synchronously. When the scraper 217 moves in the direction of the collection box 218, the inclined tip of the scraper 217 shovels up the residues on the top surfaces of the lifting plate 27 and the lower die 25. When the scraper 217 moves to the position of the collection box 218, the residues located on the inclined surface of the scraper 217 enter the interior of the collection box 218 under the action of gravity. Subsequently, with the continuous rotation of the reciprocating lead screw 213, the scraper 217 moves in the reverse direction on the top surfaces of the lifting plate 27 and the lower die 25 and resets. At this time, the cleaning of the residues on the lower die 25 and the lifting plate 27 at the residue removal station is completed. Subsequently, the residues collected inside it can be processed by disassembling the collection box 218.

[0043] It should be added that when the cooling and demoulding station is switched to the residue removal station, the top surface of the lifting plate 27 is in a state flush with the top surface of the lower die 25. Combining the above text, the lifting plate 27 is closely fitted with the inner wall of the lower die 25. Therefore, when the sound barrier 14 is demoulded at the cooling and demoulding station, in addition to the function of lifting the sound barrier 14 for demoulding, when the lifting plate 27 moves upward in the cavity of the lower die 25, the lifting plate 27 scrapes the residues on the inner side wall of the cavity of the lower die 25 and pushes the scraped residues upward to the top surfaces of the lower die 25 and the lifting plate 27. Therefore, when the top surfaces of the lower die 25 and the lifting plate 27 are flush, the residues cleaned by the scraper 217 are all the residues in the cavity of the lower die 25 and on the top surface of the lifting plate 27, that is, all the residues in the lower forming die, ensuring the integrity of the residue cleaning work and solving the problem that it is difficult to handle the corner areas in the lower forming die in the prior art.

[0044] Refer to the following Figure 7 and Figure 8 As shown, in combination with the above text, after the operation of the cleaning residual station is completed, the turntable 23 switches to the spraying and feeding station, that is, Figure 1 the station in the upper right of . At this time, the user drives the telescopic end of the electric telescopic tube 220 to extend downward through the controller, and at the same time drives the telescopic end of the hydraulic rod 26 to contract, so that the lifting plate 27 moves downward inside the lower die 25, that is, the inner cavity of the lower die 25 is formed. The lifting plate 27 is used as the bottom of the inner cavity of the lower die 25. When the telescopic end of the electric telescopic tube 220 drives the square nozzle 221 to move downward to the position where the square nozzle 221 is located inside the lower die 25, at this time, the telescopic end of the electric telescopic tube 220 no longer extends, so that the square nozzle 221 is stably limited inside the lower die 25. At this time, there is a gap between the bottom surface of the square nozzle 221 and the top surface of the lifting plate 27. This gap is used to prevent the lifting plate 27 from blocking the bottom spray holes of the square nozzle 221.

[0045] After completion, the user drives the external release agent supply device. The external release agent supply device fills the square nozzle 221 with the release agent through the corrugated pipe 222. The release agent is sprayed downward from the spray holes distributed on the side wall and bottom of the square nozzle 221 to the inner side wall of the lower die 25 and the bottom surface of the lifting plate 27. When the spraying of the release agent is completed, the user contracts the telescopic end of the electric telescopic tube 220 and shuts down the external release agent supply device. At this time, the square nozzle 221 is no longer located inside the lower die 25. After completion, the user can feed materials into the inner cavity of the lower die 25, specifically the carbon fiber composite material raw material for manufacturing the sound barrier 14.

[0046] At this point, the operation of the auxiliary component is completed. The user can rotate the hydraulic motor 21 through the controller to rotate the turntable 23 to Figure 1 the sound barrier processing station located in the upper left corner of for the next round of production and forming of the sound barrier 14.

[0047] During the operation of the above auxiliary component, by dividing the production and forming of the carbon fiber composite material sound barrier 14 into four consecutive stations that operate simultaneously and do not interfere with each other during operation, it solves the problem that in the traditional hot pressing process, the equipment is idle during steps such as cooling and demoulding. Here, four stations operate simultaneously. When one station is cooling and demoulding, other stations can perform operations such as processing, cleaning residues, spraying release agent, and feeding materials. The equipment utilization rate is greatly improved, and there is no obvious intermittency in the production process, so that more carbon fiber composite material sound barriers 14 can be produced per unit time.

[0048] Meanwhile, through the operation of the hydraulic rod 26 and the lifting plate 27, after the carbon fiber composite sound barrier 14 is cooled, it can be quickly ejected from the lower mold 25, without waiting for natural cooling and then manually or with the help of other complex tools for demoulding as in the traditional method, which greatly shortens the demoulding time, improves the production efficiency, and after the sound barrier 14 is ejected, a complete plane is formed at its bottom, and the user only needs to translate the sound barrier 14 to achieve demoulding, with simple and convenient operation, reducing the cumbersome steps in the demoulding process and further improving the demoulding efficiency.

[0049] Meanwhile, the corner blocks of the triangular positioning rod 29 can play a guiding role during the upward movement of the sound barrier 14, effectively avoiding the situation of tilting or corner damage, ensuring the integrity and appearance quality of the sound barrier 14, reducing the scrap rate of the sound barrier 14 caused by improper demoulding, and improving the yield rate of the sound barrier 14.

[0050] Meanwhile, when the lifting plate 27 is lifted, the residues on the inner cavity side wall of the lower mold 25 are scraped to the top, and the residues on the complete plane formed by the lifting plate 27 and the lower mold 25 are cleaned by the scraper 217, without the need for manual cleaning of the inside of the lower forming mold, effectively avoiding the accumulation of residues in the mold, ensuring the integrity of the residue removal work, and at the same time solving the problem that the corner areas in the lower forming mold are difficult to handle in the prior art.

[0051] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
