[0056] During the use of the present invention:

[0057] The powder in the granulation powder barrel 6 is transported to the quantitative automatic powder spreading device 9 through the powder extraction pipe 7 and the vacuum feeder 8. This device evenly fills the powder into the forming mechanism 1, which consists of a steel die core 10 and a polyurethane soft sleeve 11. The steel die core 10 is used to form the inner wall of the green blank, and the polyurethane soft sleeve 11 is used to hold the powder and transfer pressure.

[0058] The forming mechanism 1 is sent into the stamping mechanism 3 by the transmission mechanism 2. The stamping mechanism 3 applies high pressure to the powder in the forming mechanism 1 in the way of dry bag isostatic pressing to make it into a green blank of the aluminum ceramic vacuum tube shell.

[0059] After stamping is completed, the transmission mechanism 2 sends the forming mechanism 1 to directly below the grasping mechanism 4. The grasping mechanism 4 uses a robotic arm to take out the green blank from the forming mechanism 1 and transport it into the turning mechanism.

[0060] The turning mechanism consists of a frame 12, a workbench 13, a lathe 14, etc. The grasping mechanism 4 places the green blank on the workbench 13. There is a clamping mechanism on the workbench 13. The clamping mechanism consists of a rotating screw 16, a rotating block 17, a sliding mechanism, a clamping component, etc. The clamping component consists of a clamping cylinder 22 and a clamping arm 23. The clamping arm 23 is in a semi-circular arc structure and has a protective layer on its surface, which is used to clamp the left and right side walls of the green blank to avoid scratching.

[0061] When the green blank is placed on the workbench 13, it will trigger the first pressing mechanism, which consists of a first pressing plate 26, a first pressing rod 27, a first pressing torsion 28, etc. The first pressing torsion 28 is electrically connected to the rotating motor 18 and is used to control the start of the rotating motor 18. The output shaft of the rotating motor 25 is connected to the workbench 13 and is used to drive the workbench 13 to rotate, and then drive the green blank to rotate.

[0062] Meanwhile, the triggering of the first pressing mechanism also drives the rotation of the rotating screw rod 16. The rotating block 17 on the rotating screw rod 16 then moves to the right. The rotating block 17 drives the sliding block 20 to move upward along the guide rail 19 through the connecting rod. The mounting plate 21 on the sliding block 20 also moves upward accordingly, and the clamping components on the mounting plate 21 also move upward. When the clamping components rise to a certain height, the second pressing mechanism will be triggered. This mechanism consists of a second pressing plate 31, a second pressing rod 32, a second pressing torsion 33, etc. The second pressing torsion 33 is electrically connected to the clamping cylinder 22 and is used to control the opening of the clamping cylinder 22. The clamping cylinder 22 drives the clamping arms 23 to close, thereby clamping and fixing the rough blank.

[0063] After the rough blank is clamped, the lathe 14 starts to perform turning processing on its surface to remove the excess material and make it reach the required size and shape. During the turning process, the rough blank rotates continuously to ensure the uniformity and accuracy of the processing.

[0064] After the turning is completed, at this time, the fourth pressing button can be pressed. This button is electrically connected to the clamping cylinder 22 and is used to control the reset of the clamping cylinder 22, so that the clamping components return to the initial position, the clamping arms 23 open, and the rough blank is released. At the same time, the third pressing button can also be pressed. This button is electrically connected to the rotating motor 25 and is used to control the reset of the rotating motor 18. After the rough blank is released, the grasping mechanism 4 grabs it again with the robotic arm and transports it to the storage on the placement platform 5.

[0066] This application uses the dry - bag isostatic pressing method to form the powder material. This method has the advantages of short forming cycle, long service life of the mold, and being convenient for large - scale continuous production. It is suitable for preparing products with uniform specifications and simple shapes such as alumina ceramic vacuum tube shells, and can ensure the density and strength of the products, meeting the requirements of high - performance ceramic materials. This application utilizes the principle of isostatic pressing, that is, by applying uniformly distributed pressure in all directions to the powder material through liquid or gas to make it a dense green body. Isostatic pressing has the advantages of large forming pressure, high green body density, high green body strength, and complex forming shapes, and is suitable for preparing high - performance ceramic materials such as alumina ceramics. At the same time, using the dry - bag isostatic pressing method, that is, filling the powder material into a flexible pre - formed mold and then applying isostatic pressure, this method has the advantages of short forming cycle, long service life of the mold, and being convenient for large - scale continuous production, and is suitable for preparing products with uniform specifications and simple shapes such as alumina ceramic vacuum tube shells.

[0067] This application designs a clever clamping mechanism that can achieve automatic clamping and releasing of the alumina ceramic vacuum tube shell, while avoiding scratching the surface of the product, improving the accuracy and effect of turning processing, simplifying the operation process, reducing the possibility of human intervention and misoperation. Using a clamping mechanism composed of a rotating screw 16, a rotating block 17, a sliding mechanism, and a clamping component, it can achieve automatic clamping and releasing of the green body according to the placement of the green body. The clamping component adopts a semi - circular arc structure with a protective layer on the surface, which is used to clamp the left and right side walls of the green body to avoid scratching the surface of the product, improving the accuracy and effect of turning processing.

[0068] This application also designs some pressing mechanisms and extrusion buttons that can achieve automatic control and reset of the rotating motor 25 and the clamping cylinder 22, enabling the entire device to flexibly adapt to products of different specifications and quantities, increasing the intelligence and adaptability of the device. Using a control mechanism composed of a first pressing mechanism, a second pressing mechanism, a third extrusion button, a fourth extrusion button, etc., it can automatically control and reset the opening and closing of the rotating motor 25 and the clamping cylinder 22 according to the placement of the green body and the completion of turning, enabling the workbench 13 and the clamping component to be adjusted to the initial position at any time, facilitating the next forming and turning. At the same time, it also enables the entire device to flexibly adapt to products of different specifications and quantities, being unrestricted by the shape and size of the products, increasing the intelligence and adaptability of the device.

[0069] The setting of the first pressing spring 30 in this application facilitates the closing of the first pressing plate 26.
