[0002] Diamond and silicon carbide are typical hard and brittle ceramic materials. They have similar crystal structures and can form chemical bonds under certain conditions. Therefore, the interface bonding of diamond-silicon carbide two-phase composite materials is good. It is an excellent superhard composite material. Diamond-silicon carbide two-phase composite materials can be prepared by chemical vapor infiltration and high temperature and high pressure synthesis methods.

[0003] In the existing technology, such as the document with announcement number CN116425546B, a method for preparing a large-particle-size and high-proportion diamond silicon carbide composite material is specifically disclosed.

[0029] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0030] Superhard diamond silicon carbide is a ceramic-based material made of diamond and silicon carbide as the main raw materials. Superhard diamond silicon carbide combines the characteristics of two high-quality materials, diamond and silicon carbide. Diamond is the hardest material known in nature and has excellent wear resistance and corrosion resistance; while silicon carbide is a material with high hardness and high thermal conductivity. The two have a good match in structure;

[0031] When making diamond silicon carbide composite materials, a hinged six-sided top press is required to perform a high-pressure synthesis process in order to press the inner assembly block into a cylindrical shape. However, in current practice, when a traditional hinged six-sided top press is used to press the inner assembly block, it is often accompanied by significant deformation of the block. This deformation in turn causes the block to fit tightly against the inner wall of the molding tank, making it difficult to remove the molded inner assembly block from the inside of the tank.

[0032] In view of this, the present invention provides a superhard diamond silicon carbide processing device, which can realize the function of automatic unloading, thereby improving production efficiency and automation.

[0033] Specifically:

[0034] like Figure 2 - Figure 4 As shown, the present embodiment provides a device for processing superhard diamond silicon carbide, comprising a first material tank shell 12 and a second material tank shell 13, the inner wall of the first material tank shell 12 is sleeved with a second spacer 151, the inner wall of the second material tank shell 13 is sleeved with a first spacer 15, the top of the second spacer 151 is fixedly connected with a connecting block 16, the top of the first spacer 15 is fixedly connected with a bracket 161, the inner wall of the bracket 161 is rotatably connected with a first rotating shaft 17, both ends of the first rotating shaft 17 respectively pass through the bracket 161 and extend to the outside thereof, both ends of the first rotating shaft 17 are fixedly connected to a limiting sleeve 19, both ends of the first rotating shaft 17 are sleeved with a torsion spring 18, the ends of the first rotating shaft 17 respectively pass through the connecting block 16 and are fixedly connected thereto, one end of the torsion spring 18 is fixedly connected to the limiting sleeve 19, and the other end of the torsion spring 18 is fixedly connected to the bracket 161.

[0035] In some embodiments, Figure 1As shown, a device for processing superhard diamond silicon carbide also includes a chassis 1, wherein support feet 2 are fixedly connected at the four corners of the bottom of the chassis 1, and a plurality of support rods 3 are fixedly connected to the top of the chassis 1. A top plate 4 is provided above the chassis 1, and the top plate 4 is respectively fixedly connected to the plurality of support rods 3. A hydraulic cylinder 5 is fixedly connected to the top of the top plate 4, and the output end of the hydraulic cylinder 5 passes through the top plate 4 and extends to the bottom thereof, and an extrusion column 6 is fixedly connected to the output end of the hydraulic cylinder 5. By pushing the extrusion column 6 through the hydraulic cylinder 5 to pressurize the inner assembly blocks in the first spacer 15 and the second spacer 151, the cold pressing of the inner assembly blocks can be efficiently realized and pressed into a column. This cold pressing method has higher production efficiency and lower energy consumption.

[0036] In some embodiments, Figure 1 and Figure 2 As shown, both sides of the chassis 1 are fixedly connected with supporting plates 7, the tops of the two supporting plates 7 are fixedly connected with hydraulic rods 8, the output ends of the two hydraulic rods 8 are fixedly connected with connecting rods 9, the outer wall of the first material tank shell 12 is fixedly connected with a fixing rod 11, the outer wall of the fixing rod 11 is fixedly connected with a connecting plate 10, and the connecting plate 10 is respectively fixedly connected with the two connecting rods 9. The connecting plate 10 is pushed to move by the hydraulic rod 8, thereby driving the first material tank shell 12 to move, and realize separation and closure with the second material tank shell 13. This design makes the opening and closing of the first material tank shell 12 and the second material tank shell 13 flexible and convenient, and is convenient for unloading.

[0037] In some embodiments, Figure 5 and Figure 6 As shown, a support plate 20 is fixedly connected to the top of the chassis 1, a through hole 26 is opened on the top of the support plate 20, a clamping rod 25 is slidably connected to the inner wall of the through hole 26, an end cap 29 is fixedly connected to the end of the clamping rod 25, a first spring 30 is sleeved on the outer wall of the clamping rod 25, one end of the first spring 30 is fixedly connected to the end cap 29, and the other end of the first spring 30 is fixedly connected to the support plate 20. When the first material tank shell 12 is separated from the second material tank shell 13, through the cooperation of the clamping rod 25 and the first spring 30, the clamping rod 25 can quickly hit the bottom of the inner assembly block, causing it to shake and detach from the spacer, thereby realizing automatic unloading. This process reduces manual intervention, improves the degree of production automation, and reduces labor costs.

[0038] In some embodiments, Figure 6 As shown, a sliding cavity 23 is opened on the inner wall of the support plate 20, and a stop block 24 is slidably connected to the inner wall of the sliding cavity 23. The end of the stop block 24 is fixedly connected to the extension rod 22. A third spring 38 is sleeved on the outer wall of the extension rod 22. The two ends of the third spring 38 are respectively fixedly connected to the stop block 24 and the support plate 20. The end of the extension rod 22 passes through the support plate 20 and extends to its outside. The inner wall of the clamping rod 25 is rotatably connected to the connecting shaft 27, and the circumferential outer wall of the connecting shaft 27 is fixedly connected to the first roller 28.

[0039] In some embodiments, Figure 3 and Figure 5 As shown, a first guide groove 14 is formed at the bottom of the first tank shell 12 , and a second guide groove 21 is formed at the top of the support plate 20 .

[0040] In some embodiments, Figure 6 and Figure 7 As shown, the outer wall of the connecting plate 10 is fixedly connected to a connecting frame 31, the inner wall of the connecting frame 31 is fixedly connected to a sliding rod 32, the circumferential outer wall of the sliding rod 32 is sleeved with a second spring 33, the outer wall of the sliding rod 32 is slidably connected to a mounting seat 34, the end of the mounting seat 34 is slidably connected to the inner wall of the connecting frame 31, the inner wall of the mounting seat 34 is rotatably connected to a second rotating shaft 35, the circumferential outer wall of the second rotating shaft 35 is fixedly connected to a second roller 36, the circumferential outer wall of the second roller 36 is provided with an annular groove 37, the second roller 36 is in rolling contact with the extension rod 22 through the annular groove 37, one end of the second spring 33 is fixedly connected to the connecting frame 31, and the other end of the second spring 33 is fixedly connected to the mounting seat 34.

[0041] Working principle: the inner assembly block obtained in the process of preparing diamond silicon carbide is placed in the first spacer 15 and the second spacer 151, and the extrusion column 6 is pushed downward by the hydraulic cylinder 5 to pressurize the inner assembly block in the first spacer 15 and the second spacer 151 through the extrusion column 6, so as to cold-press the inner assembly block into a column;

[0042] The two hydraulic rods 8 push the connecting plate 10 to move through the connecting rod 9, and the connecting plate 10 drives the fixing rod 11 to move, and the fixing rod 11 drives the first tank shell 12 to move, so that the first tank shell 12 is separated from the second tank shell 13, and the first tank shell 12 drives the first spacer 15 and the second spacer 151 to move when the first tank shell 12 moves;

[0043] When the connecting plate 10 moves, the connecting frame 31 is driven to move, and the mounting seat 34 is driven to move through the connecting frame 31, and the second roller 36 is driven to roll along the outer wall of the extension rod 22 through the mounting seat 34;

[0044] When the first tank shell 12 moves, the first guide groove 14 at the bottom squeezes the top of the clamping rod 25. At this time, the clamping rod 25 slides toward the inside of the support plate 20 and stretches the first spring 30. The clamping rod 25 slides along the bottom of the first tank shell 12. When the clamping rod 25 is separated from the bottom of the first tank shell 12, at this time, under the elastic force of the first spring 30, the top of the clamping rod 25 quickly moves between the first spacer 15 and the second spacer 151, thereby hitting the bottom of the inner assembly block inside, causing the bottom of the inner assembly block to shake. The first tank shell 12 continues to move, and the top of the clamping rod 25 extends to between the first spacer 15 and the second spacer 151. At this time, the clamping rod 25 blocks the second spacer 151. At this time, the second spacer 151 drives the bracket 161 to rotate around the first rotating shaft 17, so that the first spacer 15 and the second spacer 151 are separated, which facilitates the internal assembly block to be separated from the first spacer 15 and the second spacer 151, so as to realize automatic unloading. The second spacer 151 continues to move, and at this time, the clamping rod 25 is free from blocking the second spacer 151.

[0045] When the connecting plate 10 continues to move and the second roller 36 is detached from the extension rod 22, the mounting seat 34 moves downward under the elastic force of the second spring 33, and the second roller 36 is moved below the extension rod 22;

[0046] After unloading, the hydraulic rod 8 drives the connecting plate 10 to move in the opposite direction. At this time, the mounting seat 34 drives the extension rod 22 to move. At this time, the third spring 38 is stretched, and the extension rod 22 drives the stopper 24 to slide along the inner wall of the sliding cavity 23. The stopper 24 squeezes the first roller 28 in the clamping rod 25, so that the clamping rod 25 slides downward along the supporting plate 20, so that the connecting plate 10 drives the first spacer 15 and the second spacer 151 to slide in the opposite direction along the top of the supporting plate 20, thereby moving the second spacer 151 to the inside of the second tank shell 13, and at the same time closing the first tank shell 12 and the second tank shell 13, and the stopper 24 passes through the clamping rod 25;

[0047] When the mounting seat 34 pushes the extension rod 22 to move, when the second roller 36 rolls along the second guide groove 21, the mounting seat 34 slides upward along the slide rod 32, so that the second roller 36 can be moved above the extension rod 22. At this time, under the pulling force of the third spring 38, the extension rod pulls the stop block 24 to slide in the opposite direction along the inner wall of the sliding cavity 23, and quickly slides through the inside of the clamping rod 25.
