[0002] Fiberglass board is a composite material made of glass fiber as reinforcement and synthetic resin as matrix through a composite process. Its pressing process typically employs lamination: resin-impregnated fiberglass cloth or felt is cut, stacked, and then fed into a hot press. Under high temperature and pressure, the resin melts and flows, fully impregnating the fibers. Subsequently, under pressure, the resin undergoes a chemical cross-linking reaction and cures, thereby tightly bonding the multiple layers of materials into a dense, high-strength board.

Through the coordinated use of a transfer mechanism, an auxiliary mechanism, and a lifting mechanism, a U-shaped plate can be driven to reciprocate, thereby enabling the simultaneous pressing, trimming, unloading, and loading of the fiberglass boards. However, during the pressing process, heating the material only from the bottom can easily lead to uneven heating. Summary of the Invention

[0009] Preferably, the limiting component further includes: The vertical tube installed inside the second corner plate and the second channel opened inside the vertical tube; A first telescopic rod and a blocking plate connected to the telescopic end of the first telescopic rod are installed inside the first chamber.

[0010] Preferably, the suction assembly includes: An adjustment rod installed above the skateboard and a fixing tube connected to the adjustment rod; A connector installed on the outside of a fixed pipe; The connecting cylinder is installed on the outside of the fixed pipe and away from the end of the connector.

An inclined plate installed on the outside of the connecting cylinder is used to scrape the lower surface of the pressure plate.

[0012] This invention provides a sheet metal pressing process under high pressure, comprising the following steps: S1. Before using the equipment, the suction assembly, in conjunction with the pressure plate, completes the suction work on the base plate, upper mold, and pressure plate. S2. Place the material between the four second corner plates to complete the placement and positioning of the material. S3. Merge the upper mold and the base plate, and the vertical pipe enters the upper mold to supply hot air to the upper mold; S4. Use heaters and hot air supply to heat the bottom and sides of the material; S5. After heating the material, perform multiple pre-pressing operations, and then complete the pressing operation on the material.

[0013] This invention provides a sheet metal pressing device and process under high pressure. It has the following beneficial effects: 1. This high-pressure sheet metal pressing equipment and its process utilizes a vertically movable upper mold and base plate, forming a pressing groove. A second chamber is created inside the upper mold and connected to the outside via a first channel in the first corner plate. Combined with a heater in the base, this achieves dual heating of the material's bottom and surrounding area. Existing equipment heats the material only from the bottom during pressing, easily leading to uneven heating. Therefore, the upper mold and base plate not only allow heat to be directly transferred to the bottom of the material via the base but also allow hot air to be delivered to the second chamber of the upper mold via an external fan through the first channel, enabling simultaneous side heating of the material by the upper mold. This reduces the risk of partial discharge caused by internal temperature differences in the material under high pressure.

[0014] 2. The sheet metal pressing equipment and its process under high pressure environment, through the setting of processing mechanisms and limiting components, respectively limit the material and the upper mold. The second lifting rod drives the lifting of the second corner plate and the vertical tube, which can both physically contain the material during loading and complete the docking of the upper mold and the bottom plate during mold closing.

[0015] 3. The sheet metal pressing equipment and its process under high pressure environment, by setting up a processing mechanism and limiting components, when the external fan supplies air, the heated gas enters the bottom plate, the first chamber and the second chamber of the upper mold through the connecting pipe, so as to heat the upper mold and transfer the temperature to the side of the material.

[0016] 4. The sheet metal pressing equipment and its process under high pressure include a processing mechanism and a suction assembly. An arc-shaped plate and a third channel are installed at the bottom of the connecting cylinder. Before pressing, the bottom plate is moved and suctioned to remove large particles of impurities. After the hydraulic cylinder drives the pressure plate to scrape the inner wall of the upper mold downwards, the arc-shaped plate at the top of the connecting cylinder is used to suction out the fallen impurities, and the inclined plate is used to scrape off the residue on the lower surface of the pressure plate during the movement.

[0017] 5. The sheet metal pressing equipment and its process under high pressure environment, by setting up a lifting mechanism and a processing mechanism, heats the bottom and surrounding area of ​​the material before pressing, and pre-presses the material with the help of the pressure plate, and removes air gaps before pressing the material to reduce the risk of partial discharge of the material.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figures 1-9 As shown, the present invention provides a technical solution: a sheet metal pressing device under high pressure environment, which is described below.

[0022] Including base 1, it also includes: The connecting column 2 installed on the base 1 and the top plate 3 connected to the connecting column 2; The first lifting rod 6 is set below the top plate 3 and is configured as an electric push rod. A first groove 10 is formed inside the base 1 and a base plate 8 is slidably connected inside the first groove 10; The lifting mechanism 7 is provided on the telescopic end of the first lifting rod 6. The lifting mechanism 7 includes an upper mold 701 connected to the telescopic end of the first lifting rod 6, a first corner plate 702 installed below the upper mold 701, and a first channel 703 opened inside the first corner plate 702. The first lifting rod 6 is used to adjust the distance between the upper mold 701 and the bottom plate 8. The upper mold 701 and the bottom plate 8 form a pressure groove. A ventilation hole is opened at the center of the top of the upper mold 701. A second chamber is opened inside the upper mold 701. The second chamber is connected to the first channel 703. Hydraulic cylinder 4 installed above top plate 3 and pressure plate 12 connected to the telescopic end of hydraulic cylinder 4; The first groove 5 is formed inside the top plate 3, and the first lifting rod 6 is installed inside the first groove 5; The processing mechanism 9 is located above the base plate 8 and the connecting pipe 11 is installed below the base 1. The connecting pipe 11 is connected to an external fan and passes through the interior of the base 1. A heater is installed inside the base 1.

[0023] When using the equipment, adjust the processing mechanism 9, which in turn moves the base plate 8 away from the base 1. The worker manually places the material into the processing mechanism 9. Then, the processing mechanism 9 drives the base plate 8 to move below the pressure plate 12. Once the base plate 8 is below the pressure plate 12, activate the first lifting rod 6. The first lifting rod 6 drives the upper mold 701 and the first corner plate 702 downwards, allowing the upper mold 701 to rest on the base plate 8, with the material inside. Activate the heater in the base 1. The temperature is transferred through the base 1 to the base plate 8 and then to the material, heating it. Adjust the hydraulic cylinder 4, which drives the pressure plate 12 to perform multiple pre-pressing operations on the material before completing the pressing process. Subsequently, by adjusting the processing mechanism 9, the first lifting rod 6, and the pressure plate 12, the material is separated from the upper mold 701. The position of the base plate 8 is adjusted, and the base plate 8 moves the material away from the base 1. The pressed material is then manually removed.

[0024] Processing unit 9 includes: The second groove 901 and the second slide 903 are formed inside the base plate 8; A limiting component 902 is disposed inside the second groove 901; A sliding plate 904 and a suction component 905 connected to the sliding plate 904 are slidably connected inside the second slide groove 903. The first push rod 906 is installed inside the second slide 903. The slide plate 904 is connected to the telescopic end of the first push rod 906. The first push rod 906 is set as an electric push rod. The first push rod 906 drives the slide plate 904 and the suction assembly 905 to move above the base plate 8. The second push rod 907 is located outside the base plate 8 and is installed inside the first slide groove 10. The second push rod 907 drives the base plate 8 to move in the horizontal direction.

[0025] The process of placing materials using processing mechanism 9: Before using the equipment, activate the second push rod 907, which drives the base plate 8 to move away from the base 1. Adjust the limiting component 902 and manually place the material on the base plate 8, ensuring the material is within the limiting component 902 to prevent it from shifting.

[0026] The process of adjusting the temperature of the material using processing mechanism 9: Adjust the second push rod 907 to its initial state. The second push rod 907 drives the base plate 8 back to its original position, and the base plate 8 gradually moves below the pressure plate 12. The bottom of the base plate 8 gradually aligns with the position of the connecting pipe 11. Start the heater, and the temperature is transferred to the base plate 8 through the base 1, and then to the material, heating the material. Start the external fan and adjust the air supply temperature. The gas enters the base plate 8 through the connecting pipe 11, and enters the upper mold 701 through the limiting component 902, supplying air to heat the upper mold 701. The upper mold 701 transfers the temperature to the material from the side, promoting the material's heating.

[0027] The working process of using processing mechanism 9 to limit the position of upper mold 701: Start the first lifting rod 6, which drives the upper mold 701 to move downward. Adjust the limiting component 902 to limit the position of the upper mold 701. The upper mold 701 and the base plate 8 form a pressing groove.

[0028] The process of using processing unit 9 to receive impurities: Before placing the material, the first push rod 906 is activated. The first push rod 906 gradually moves the slide plate 904 and the suction assembly 905 towards the second push rod 907 to perform impurity suction on the upper surface of the base plate 8. The slide plate 904 gradually moves to the position closest to the second push rod 907, and the hydraulic cylinder 4 is adjusted. The hydraulic cylinder 4 drives the pressure plate 12 to scrape the inner wall of the upper mold 701 downward, causing impurities to detach from the inner wall of the upper mold 701. The suction assembly 905 sucks up the falling impurities and the impurities on the pressure plate 12.

[0029] The process of using processing mechanism 9 to discharge materials: After pressing, adjust the first lifting rod 6 and the limiting component 902. As the first lifting rod 6 moves the upper mold 701 upward, the pressure plate 12 contacts the material, and the limiting component 902 gradually contacts the material. Adjust the hydraulic cylinder 4, and the pressure plate 12 gradually moves away from the material. Activate the second push rod 907, which drives the base plate 8 to move away from the base 1, thereby moving the material away from the base 1. Then adjust the limiting component 902, and the user can pick up the pressed material.

[0030] By setting up an upper mold 701 and a base plate 8 that can move vertically, forming a pressure groove, and opening a second chamber inside the upper mold 701, which is connected to the outside through a first channel 703 in the first corner plate 702, the material's bottom and surrounding area are heated simultaneously by the heater in the base 1. The upper mold 701 and base plate 8 not only allow heat to be directly transferred to the bottom of the material through the base 1, but also allow hot air to be sent into the second chamber of the upper mold 701 through the first channel 703 via an external fan, enabling the upper mold 701 to simultaneously heat the material from the side. This reduces the risk of partial discharge caused by internal temperature differences in the material under high pressure.

[0031] Limiting component 902 includes: A first chamber 9021 is formed inside the base plate 8, and the first chamber 9021 is connected to the second groove 901; Fixing plate 9028 installed inside the first chamber 9021; The second lifting rod 9022 is provided above the fixed plate 9028 and the second corner plate 9023 is connected to the telescopic end of the second lifting rod 9022. The second lifting rod 9022 is configured as an electric push rod. The vertical tube 9024 installed inside the second corner plate 9023 and the second channel 9025 opened inside the vertical tube 9024; A first telescopic rod 9026 and a blocking plate 9027 connected to the telescopic end of the first telescopic rod 9026 are disposed inside the first chamber 9021.

[0032] The process of using the limiting component 902 to limit the material: Activate the second lifting rod 9022, which drives the second corner plate 9023 and the vertical tube 9024 to move upward. After moving upward, the second corner plate 9023 remains in the second groove 901. Manually place the material between the four second corner plates 9023 to complete the placement and positioning of the material.

[0033] The working process of using the limiting component 902 to limit the position of the upper mold 701: Subsequently, the second push rod 907 drives the base plate 8 to move below the pressure plate 12. Once the base plate 8 is below the pressure plate 12, the first lifting rod 6 is activated. The first lifting rod 6 drives the upper mold 701 and the first corner plate 702 to move down, gradually adjusting the second lifting rod 9022 to the initial state. The second corner plate 9023 gradually sinks into the second groove 901, and the upper mold 701 falls onto the base plate 8. The first corner plate 702 at the bottom of the upper mold 701 enters the second groove 901, and the vertical tube 9024 enters the first channel 703. At this time, the material is in the upper mold 701, thus completing the limiting work for the material and the upper mold 701.

[0034] The process of using limit component 902 to supply air to upper mold 701: As the base plate 8 moves below the pressure plate 12, the bottom of the base plate 8 gradually aligns with the position of the connecting pipe 11. The heater is activated, and the temperature is transferred from the base 1 to the base plate 8, and then to the material, heating the material. The external fan is activated, and the air supply temperature is adjusted. Gas enters the base plate 8 through the connecting pipe 11, pushing the blocking plate 9027 upward. At this time, the first telescopic rod 9026 is compressed, and the gas enters the second groove 901 through the first chamber 9021, and then enters the second chamber inside the upper mold 701 through the vertical pipe 9024, supplying air to heat the upper mold 701. The upper mold 701 transfers the temperature from the side to the material, promoting the material's temperature rise.

[0035] The process of using limit component 902 to assist in material discharge: As the first lifting rod 6 moves the upper mold 701 upward, the pressure plate 12 remains in contact with the material. The second lifting rod 9022 is then activated, which drives the second corner plate 9023 to move upward, and the second corner plate 9023 comes into contact with the material.

[0036] Activate the second push rod 907, which drives the base plate 8 to move away from the base 1, thereby moving the material away from the base 1. Then adjust the stroke of the second lifting rod 9022, which drives the second corner plate 9023 into the second groove 901, allowing the user to pick up the pressed material.

[0037] By setting up the processing mechanism 9 and the limiting component 902, the material and the upper mold 701 are respectively limited. The second lifting rod 9022 drives the second corner plate 9023 and the vertical tube 9024 to rise and fall, which can not only physically block the material during loading, but also complete the docking of the upper mold 701 and the base plate 8 during mold closing.

[0038] The suction assembly 905 includes: An adjusting rod 9051 and a fixing tube 9052 connected to the adjusting rod 9051 are provided above the sliding plate 904. The connector 9057 is installed on the outside of the fixed pipe 9052, and the connector 9057 is connected to an external exhaust fan. Connecting cylinder 9053 is installed outside the fixed pipe 9052 and away from the end of the connector 9057; The arc-shaped plate 9055 and the partition plate 9058 are disposed inside the connecting cylinder 9053. The partition plate 9058 is detachably installed inside the connecting cylinder 9053, and adhesive strips are provided on both the upper and lower surfaces of the partition plate 9058. The third channel 9056 is located inside the curved plate 9055; Inclined plate 9054 installed outside the connecting cylinder 9053.

[0039] The process of using suction assembly 905 to collect impurities: Before placing the materials, start the exhaust fan and start the first push rod 906. The first push rod 906 gradually drives the slide plate 904 and the suction component 905 to move closer to the second push rod 907. During the movement, the third channel 9056 of the bottom arc plate 9055 of the connecting cylinder 9053 begins to perform impurity suction on the upper surface of the bottom plate 8.

[0040] The slide plate 904 gradually moves to the position closest to the second push rod 907. The hydraulic cylinder 4 is adjusted, and the hydraulic cylinder 4 drives the pressure plate 12 to scrape the inner wall of the upper mold 701 downward, causing impurities to detach from the inner wall of the upper mold 701. The third channel 9056 of the top arc plate 9055 of the connecting cylinder 9053 begins to suck up the impurities. The stroke of the first push rod 906 is adjusted, and the first push rod 906 drives the inclined plate 9054 to scrape the lower surface of the pressure plate 12 while scraping, sucking up the impurities.

[0041] By setting up a processing mechanism 9 and a suction assembly 905, and by setting an arc-shaped plate 9055 and a third channel 9056 at the bottom of the connecting cylinder 9053, the bottom plate 8 is moved and suctioned before pressing to remove large particles of impurities. After the hydraulic cylinder 4 drives the pressure plate 12 to scrape the inner wall of the upper mold 701 downward, the arc-shaped plate 9055 at the top of the connecting cylinder 9053 is used to suck up the fallen impurities, and the inclined plate 9054 is used to scrape off the residue on the lower surface of the pressure plate 12 during the movement.

[0042] Working principle: Before using the equipment, activate the second push rod 907, which drives the base plate 8 to move away from the base 1. Activate the second lifting rod 9022, which drives the second corner plate 9023 and the vertical tube 9024 to move upwards. After moving upwards, the second corner plate 9023 remains in the second groove 901. Manually place the material between the four second corner plates 9023 to complete the material placement and positioning.

[0043] Subsequently, the second push rod 907 drives the base plate 8 to move below the pressure plate 12. Once the base plate 8 is below the pressure plate 12, the first lifting rod 6 is activated. The first lifting rod 6 drives the upper mold 701 and the first corner plate 702 to move down, gradually adjusting the second lifting rod 9022 to the initial state. The second corner plate 9023 gradually sinks into the second groove 901, and the upper mold 701 falls onto the base plate 8. The first corner plate 702 at the bottom of the upper mold 701 enters the second groove 901, and the vertical tube 9024 enters the first channel 703. At this time, the material is in the upper mold 701, thus completing the limiting work for the material and the upper mold 701.

[0044] As the base plate 8 moves below the pressure plate 12, the bottom of the base plate 8 gradually aligns with the position of the connecting pipe 11. The heater is activated, and the temperature is transferred from the base 1 to the base plate 8, and then to the material, heating the material. The external fan is activated, and the air supply temperature is adjusted. Gas enters the base plate 8 through the connecting pipe 11, pushing the blocking plate 9027 upward. At this time, the first telescopic rod 9026 is compressed, and the gas enters the second groove 901 through the first chamber 9021, and then enters the second chamber inside the upper mold 701 through the vertical pipe 9024, supplying air to heat the upper mold 701. The upper mold 701 transfers the temperature from the side to the material, promoting the material's temperature rise.

[0045] Adjust the hydraulic cylinder 4. The hydraulic cylinder 4 drives the pressure plate 12 to perform multiple pre-pressing operations on the material before completing the pressing operation on the material.

[0046] After pressing is completed, adjust the first lifting rod 6 and the limiting component 902. As the first lifting rod 6 moves the upper mold 701 upward, the pressure plate 12 remains in contact with the material. Activate the second lifting rod 9022, which drives the second corner plate 9023 to move upward, bringing the second corner plate 9023 into contact with the material.

[0047] Adjust the hydraulic cylinder 4, and the pressure plate 12 gradually moves away from the material. Start the second push rod 907, which drives the base plate 8 to move away from the base 1, thereby moving the material away from the base 1. Then adjust the stroke of the second lifting rod 9022, which drives the second corner plate 9023 into the second groove 901, allowing the user to pick up the pressed material.

[0048] This invention provides a sheet metal pressing process under high pressure, comprising the following steps: S1. Before using the equipment, the suction assembly 905 works in conjunction with the pressure plate 12 to complete the suction work on the base plate 8, the upper mold 701 and the pressure plate 12.
