[0002] Silicon carbide ceramics are a type of ceramic material made of silicon carbide. Silicon carbide ceramic plates have excellent high-temperature mechanical properties, high hardness, corrosion resistance and thermal stability. In the manufacturing process of silicon carbide ceramic plates, silicon carbide raw materials need to be pressed into silicon carbide ceramic plates.

[0003] The production process of silicon carbide ceramic pressing requires a silicon carbide ceramic pressing device. Chinese utility model patent with announcement number CN221436725U discloses a silicon carbide ceramic plate pressing device, which includes a fixed frame. The fixed frame is a hollow cuboid with an opening on one side. The main hydraulic component includes a first hydraulic column, which is fixedly connected to the bottom of the top plate of the fixed frame. The output shaft of the first hydraulic column is fixedly connected to a main pressure hammer annular limiting block. Multiple locking bolts are evenly connected on the circumference of the limiting block. The output shaft of the first hydraulic column is respectively provided with annular first limiting groove and second limiting groove.

[0004] In the process of realizing this application, the technology has at least the following problems: the silicon carbide ceramic plate pressing device adopts a hydraulic method, which can achieve a certain pressing effect, but often has problems such as uneven pressing and difficulty in discharging, and cannot meet the use requirements. Therefore, a pressing device for silicon carbide ceramics is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a pressing device for silicon carbide ceramics, which has advantages such as uniform pressing. It solves the problem that existing silicon carbide ceramic plate pressing devices use hydraulic methods, which, although they can achieve a certain pressing effect, often suffer from uneven pressing and difficulty in discharging, thus failing to meet the application requirements.

[0006] In summary, this application provides the following technical solution: a pressing device for silicon carbide ceramics, including a base, a vertical plate fixedly connected to the top of the base, a mounting plate fixedly connected to the top of the vertical plate, and a pressing groove box fixedly connected to the top of the base. The upper surface of the mounting plate is provided with a pressing mechanism extending to its lower surface, and the outside of the pressing groove box is provided with a pushing mechanism extending to its interior.

[0007] The pressing mechanism includes a geared motor fixedly mounted on the upper surface of the mounting plate, a crank fixedly connected to the output shaft of the geared motor, a swing rod hinged to the end of the crank away from the geared motor, a moving rod hinged to the end of the swing rod away from the crank, and a pressure plate fixedly connected to the bottom of the moving rod.

[0008] The pushing mechanism includes a first electric push rod fixedly installed on the back of the upright plate and a push plate fixedly connected to the output end of the first electric push rod.

[0009] This application, by adopting the above-mentioned technical solution, uses a controller to start a geared motor that drives a crank to swing, causing the swing rod to move the moving rod and the pressure plate in a reciprocating motion, achieving precise pressing operation. The controller precisely controls the geared motor, enabling precise control of the pressure plate position and pressure, ensuring accuracy and consistency during the pressing process. The geared motor, through the mechanical structure of the crank and swing rod, converts rotary motion into linear motion, effectively transmitting power and improving pressing efficiency. Furthermore, the device's compact design and small footprint make it suitable for integration into automated production lines, improving space utilization. The controller activates the second electric push rod to extend and retract, moving the baffle plate out of the pressure chamber. Then, the controller activates the first electric push rod to extend and retract, moving the push plate back and forth. This automated material handling process accelerates the production pace, improves production efficiency, and shortens the production cycle. The controller's simple operating interface makes the operation easy for the operator. Operators can easily control the movement of the push plate without complicated manual operations, achieving automatic removal after pressing. This not only improves production efficiency and safety but also helps improve product quality and reduce production costs, achieving the advantages of uniform pressing and efficient material output. The controller starts the vibration motor, driving the two connecting shafts to rotate and transmit power to the two eccentric blocks, causing the entire equipment to vibrate. This ensures uniform vibration of the raw materials in the pressing box, preventing hollow areas in the pressed products due to uneven material stacking, thus improving the overall quality of the finished product. The eccentric blocks change the rotor's center of gravity, generating centrifugal force and producing a stronger vibration effect. This also makes the equipment run more smoothly, reducing noise and vibration. The uniform vibration accelerates the flow and filling speed of raw materials, reducing waiting time during pressing and improving production efficiency, resulting in strong practicality.

[0010] Furthermore, the geared motor is fixedly mounted on the upper surface of the mounting plate via a mounting bracket, the crank is oscillatingly connected to the upper surface of the mounting plate, and the moving rod is slidably connected to the inside of the mounting plate.

[0011] The beneficial effects of adopting the above-mentioned further solution are: by using the mechanical structure of the geared motor to drive the crank and the swing rod, the rotary motion is converted into linear motion, effectively transmitting power and improving the pressing efficiency.

[0012] Furthermore, a limiting sleeve adapted to the moving rod is fixedly installed inside the mounting plate. The moving rod is slidably connected inside the limiting sleeve, and the outer diameter of the moving rod is adapted to the inner diameter of the limiting sleeve.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting a limit sleeve, the stability of the moving rod's up-and-down reciprocating movement is improved.

[0014] Furthermore, the pressure plate is a solid cuboid, and the outer diameter of the pressure plate is adapted to the inner diameter of the pressure groove box.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the moving rod and the pressure plate are driven to move up and down reciprocally by the swing rod, so as to achieve precise pressing operation.

[0016] Furthermore, the top of the pressure plate is fixedly connected to two guide rods that extend to the upper surface of the mounting plate, and the guide rods are slidably connected inside the mounting plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting guide rods, the stability of the pressure plate moving up and down is improved.

[0018] Furthermore, the push plate abuts against the inner wall of the pressing box, and the inside of the pressing box has a movable opening adapted to the output end of the first electric push rod.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the push plate is moved by the extension and retraction of the first electric push rod, so that the pressing is automatically removed without complicated manual operation.

[0020] Furthermore, the outside of the pressing box is provided with a shielding mechanism extending into its interior. The shielding mechanism includes a mounting base fixedly installed on the outside of the base. A second electric push rod is fixedly installed inside the mounting base. A shielding plate is fixedly connected to the output end of the second electric push rod. The shielding plate is slidably connected to one side inside the pressing box.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the second electric push rod is activated by the controller to move the baffle plate out of the pressure box.

[0022] Furthermore, the base is provided with a vibration mechanism, which includes a mounting box fixedly installed inside the base. A vibration motor is fixedly installed inside the mounting box.

Detailed Implementation

[0033] Please see Figures 1 to 4 This embodiment of a silicon carbide ceramic pressing device includes a base 1, a vertical plate 2 fixedly connected to the top of the base 1, a mounting plate 3 fixedly connected to the top of the vertical plate 2, and a pressing box 4 fixedly connected to the top of the base 1. The upper surface of the mounting plate 3 is provided with a pressing mechanism extending to its lower surface. The outside of the pressing box 4 is provided with a pushing mechanism extending to its interior. The pressing mechanism includes a reduction motor 5 fixedly installed on the upper surface of the mounting plate 3, a crank 6 fixedly connected to the output shaft of the reduction motor 5, a swing rod 7 hinged to the end of the crank 6 away from the reduction motor 5, a moving rod 8 hinged to the end of the swing rod 7 away from the crank 6, and a pressing plate 10 fixedly connected to the bottom of the moving rod 8.

[0034] The controller starts the geared motor 5, which drives the crank 6 to swing. This causes the swing rod 7 to drive the moving rod 8 and the pressure plate 10 to move up and down reciprocally, achieving precise pressing operation. By precisely controlling the geared motor 5, the position and pressure of the pressure plate 10 can be precisely controlled, ensuring accuracy and consistency during the pressing process. The geared motor 5, through the mechanical structure of the crank 6 and the swing rod 7, converts rotary motion into linear motion, effectively transmitting power and improving pressing efficiency. In addition, the device has a compact design, occupies little space, and is suitable for integration into automated production lines, improving space utilization.

[0035] The geared motor 5 is fixedly mounted on the upper surface of the mounting plate 3 via a mounting bracket. The crank 6 is oscillatingly connected to the upper surface of the mounting plate 3, and the moving rod 8 is slidably connected to the interior of the mounting plate 3. The geared motor 5 can adjust its working speed and force according to actual needs, reducing energy waste and achieving energy-saving operation. The stability of the crank-connecting rod mechanism makes the movement of the pressure plate 10 smoother, reducing product quality problems caused by pressure fluctuations. The modular design of this device makes maintenance and replacement of parts more convenient, reducing long-term maintenance costs. By adjusting the controller parameters, it can adapt to the pressing needs of silicon carbide ceramics of different shapes and sizes, improving the versatility of the device.

[0036] Specifically, a limiting sleeve 12 adapted to the moving rod 8 is fixedly installed inside the mounting plate 3. The moving rod 8 is slidably connected inside the limiting sleeve 12, and the outer diameter of the moving rod 8 is adapted to the inner diameter of the limiting sleeve 12.

[0037] It should be noted that the pressure plate 10 is a solid cuboid, and its outer diameter matches the inner diameter of the pressure groove box 4. Two guide rods 11 are fixedly connected to the top of the pressure plate 10, extending to the upper surface of the mounting plate 3. The guide rods 11 are slidably connected inside the mounting plate 3. By setting the guide rods 11, the stability of the pressure plate 10's vertical movement is improved.

[0038] Please see Figure 2 In this embodiment, the material pushing mechanism includes a first electric push rod 13 fixedly installed on the back of the upright plate 2 and a push plate 14 fixedly connected to the output end of the first electric push rod 13. The controller activates the extension and retraction of the first electric push rod 13, causing the push plate 14 to move back and forth. This automated material handling process accelerates the production pace, improves production efficiency, and shortens the production cycle. The controller's simple operating interface allows operators to easily control the movement of the push plate 14 without complex manual operations, achieving automatic removal after pressing. This not only improves production efficiency and safety but also helps to improve product quality and reduce production costs.

[0039] The push plate 14 abuts against the inner wall of the pressing box 4, and the inside of the pressing box 4 is provided with a moving port that is adapted to the output end of the first electric push rod 13.

[0040] Please see Figure 2 In this embodiment, the pressing box 4 is provided with a shielding mechanism extending into its interior. The shielding mechanism includes a mounting base 15 fixedly installed on the exterior of the base 1. A second electric push rod 16 is fixedly installed inside the mounting base 15. A shielding plate 17 is fixedly connected to the output end of the second electric push rod 16. The shielding plate 17 is slidably connected to one side inside the pressing box 4. The second electric push rod 16 is activated by the controller to extend and retract, moving the shielding plate 17 out of the pressing box 4.

[0041] Please see Figure 4In this embodiment, a vibration mechanism is provided inside the base 1. The vibration mechanism includes a mounting box 9 fixedly installed inside the base 1. A vibration motor 18 is fixedly installed inside the mounting box 9. Connecting shafts 19 are fixedly connected to the two output shafts of the vibration motor 18. Eccentric blocks 20 are fixedly connected to the ends of the two connecting shafts 19 away from the vibration motor 18. The vibration motor 18 is started by the controller, which drives the two connecting shafts 19 to rotate, thus transmitting power to the two eccentric blocks 20. This causes the entire equipment to vibrate, ensuring that the raw materials in the pressing box 4 vibrate evenly. This prevents the pressed finished products from having hollow areas due to uneven material stacking in the pressing box 4, thereby improving the overall quality of the finished products. The function of the eccentric blocks 20 is to change the center of gravity of the rotor, generating centrifugal force, making the equipment vibrate more strongly, while making the equipment run more smoothly, reducing noise and vibration. The uniform vibration can also accelerate the flow and filling speed of raw materials, reduce waiting time during the pressing process, and improve production efficiency, achieving the advantages of strong practicality.

[0042] The working principle of the above embodiments is as follows:

[0043] In operation, silicon carbide ceramic raw materials are placed inside the pressing chamber 4. The controller starts the geared motor 5, which drives the crank 6 to swing, causing the swing rod 7 to move the moving rod 8 and the pressing plate 10 in a reciprocating motion, achieving precise pressing. The controller precisely controls the geared motor 5, allowing for precise control of the position and pressure of the pressing plate 10. The geared motor 5, through the mechanical structure of the crank 6 and the swing rod 7, converts rotary motion into linear motion, effectively transmitting power and improving pressing efficiency. Then, the controller starts the vibration motor 18, which drives the two connecting shafts 19 to rotate, transmitting power to the two eccentric blocks 20, causing the entire device to vibrate. This ensures uniform vibration of the raw materials inside the pressing chamber 4, resulting in a more uniform pressed finished product. Uneven material stacking in the pressing box 4 can cause hollow areas in the pressed product, thus improving the overall quality of the finished product. The eccentric block 20 changes the center of gravity of the rotor, generating centrifugal force, making the equipment vibrate more strongly, while making the equipment run more smoothly and reducing noise and vibration. The controller starts the second electric push rod 16 to extend and retract, moving the baffle plate 17 out of the pressing box 4. Then, the controller starts the first electric push rod 13 to extend and retract, driving the push plate 14 to move back and forth. The automated material handling process speeds up the production rhythm, improves production efficiency, and shortens the production cycle. The simple operation interface of the controller allows the operator to easily control the movement of the push plate 14 without complicated manual operation, realizing automatic removal after pressing.
