Description

Technical Field

[0001] This invention relates to the field of superhard material processing technology, and in particular to a green synthesis process for superhard materials and an energy-saving high-pressure device. Background Technology

[0002] Superhard materials refer to high-strength functional materials with a Vickers hardness higher than 40 GPa. They mainly include two categories: synthetic diamond and cubic boron nitride. They have extremely high hardness, excellent thermal conductivity, and wide bandgap semiconductor properties. In the production process of synthetic diamond, the hinged six-sided hydraulic press has become the mainstream industrial equipment for processing synthetic diamond due to its unique structural advantages.

[0003] A hinged six-sided hydraulic press typically consists of hinged beams, hinge lugs, pins, hydraulic cylinders, and top hammers. The hinge lugs on the periphery of the six hinged beams are hinged together to form a hexahedron by multiple pins. The hydraulic cylinders are installed inside each set of hinged beams, and their output ends are connected to the top hammers. Its working principle is as follows: A sealing medium such as pyrophyllite is placed at the center of the compression by multiple sets of top hammers. The hydraulic cylinders are activated, and they drive the top hammers to compress the sealing medium such as pyrophyllite. The multiple sets of top hammers contact the sealing medium such as pyrophyllite to form a high-pressure chamber. The high-pressure chamber has an internal electric heating device, and the top hammers also act as electrodes, raising the temperature at the center of the chamber to meet the temperature and pressure conditions for the synthesis of superhard materials. At this time, the top hammers continuously apply high pressure and high temperature to the sealing medium such as pyrophyllite, ultimately forming superhard materials such as synthetic diamonds under high pressure.

[0004] During continuous extrusion, if the sealing medium such as pyrophyllite has quality problems, it may suddenly break. The top hammer will then move instantaneously due to inertia, causing a collision and resulting in "top hammer backfiring," which seriously affects the service life of the top hammer. Therefore, this application proposes a green synthesis process for superhard materials and an energy-saving high-pressure device. Summary of the Invention

[0005] The purpose of this invention is to address the problem of sudden breakage of sealing media such as pyrophyllite, resulting in top hammer collision, in the prior art, and to propose a green synthesis process for superhard materials and an energy-saving high-pressure device.

[0006] In a first aspect, the present invention provides a green synthetic energy-saving high-pressure device for superhard materials, comprising six sets of hinge beams arranged in an upward, downward, left, right, front, and rearward orientation. Each set of hinge beams has four sets of hinge lugs arranged in a circular array fixed to its outer side. Adjacent sets of hinge lugs are joined together, and a pin is inserted into the joined sets of hinge lugs. Each set of hinge beams has a hydraulic cylinder installed inside, and a top hammer is installed at one end of each hydraulic cylinder. The device also includes:

[0007] A metal rod is fixed to the outside of multiple sets of top hammers. A traction rope is fixed to the end of the metal rod away from the top hammer. A connecting rod is fixed to the end of the hinge beam away from the top hammer. A limit roller is rotatably connected to the outside of the connecting rod. The end of the traction rope away from the metal rod is wrapped around the outside of the limit roller. A coil spring is fixed to the outside of the connecting rod. The end of the coil spring away from the connecting rod is fixed to the bottom end of the limit roller.

[0008] A collar is fixed to one end of the hinge beam near the limiting roller. Multiple sets of locking teeth are fixed to the inner side of the collar. A centrifugal locking mechanism is provided at the top of the limiting roller, which cooperates with the locking teeth to limit the instantaneous movement of the top hammer.

[0009] The acceleration mechanism, connected to the centrifugal engagement mechanism, is used to accelerate the engagement speed of the centrifugal engagement mechanism with the engagement teeth during operation.

[0010] Optionally, the centrifugal locking mechanism includes a centrifugal tube, a gravity ball, a pressure plate, a support rod, a locking plate, a rotating shaft, and a compression spring. The centrifugal tube is fixed to the top of the limiting roller. The gravity ball is disposed inside the centrifugal tube. The pressure plate is slidably connected to the inner wall of the centrifugal tube. The support rod is fixed to the end of the pressure plate away from the gravity ball, and the support rod passes through the centrifugal tube and extends to the outside of the centrifugal tube. A locking plate is provided at the top of the limiting roller. A rotating shaft is fixed inside the locking plate. The rotating shaft is rotatably connected to the top of the limiting roller. The support rod is hinged to the locking plate. The compression spring is fixed between the inner wall of the centrifugal tube and the pressure plate.

[0011] Optionally, the acceleration mechanism includes a sealed box, a metal elastic plate, and a gas delivery pipe. The sealed box is fixed to the top of the limiting roller, and the interior of the sealed box is filled with sodium azide. The metal elastic plate is fixed to the outside of the rotating shaft located inside the sealed box. Multiple sets of friction teeth are formed on the inner wall of the sealed box. The two ends of the gas delivery pipe are respectively fixed to the interior of the sealed box and the centrifuge tube, and the end of the gas delivery pipe near the centrifuge tube is located on the side of the pressure plate near the gravity ball.

[0012] Optionally, the gravity ball is designed to be "spherical", and the diameter of the gravity ball is adapted to the size of the inner wall of the centrifuge tube. The inner wall of the centrifuge tube and the pressure plate are both made of rubber.

[0013] Optionally, a pressure relief pipe is fixedly connected to the end of the hydraulic cylinder away from the top hammer. A semicircular plate is fixedly connected to the inner wall of the pressure relief pipe. A semicircular plate is slidably connected to the inner wall of the pressure relief pipe. Two sets of limiting rods are fixedly connected to the end of the semicircular plate away from the hydraulic cylinder. A horizontal plate is fixedly connected to the end of the two sets of limiting rods away from the semicircular plate. A horizontal plate is slidably connected to the outer side of the limiting rod. The horizontal plate is fixedly connected to the semicircular plate. Two sets of tension springs are fixedly connected between the horizontal plate and the horizontal plate. A metal rod is fixedly connected to the outer side of the metal rod. A traction rope is provided at the end of the metal rod away from the metal rod. An adjustment mechanism is provided between the metal rod and the traction rope. The adjustment mechanism is used to adjust the tension of the traction rope. A metal rod is fixedly connected to the end of the traction rope away from the metal rod. A blocking mechanism is provided around the metal rod. The blocking mechanism is used to limit the displacement of the semicircular plate.

[0014] Optionally, the blocking mechanism includes a side arc plate, a baffle, two sets of limiting rods, a receiving box, and a compression spring. The side arc plate is fixedly connected to a metal rod. The baffle is fixedly connected to the end of the side arc plate away from the metal rod. The baffle passes through the pressure relief pipe and is attached to the semi-circular plate. Both sets of limiting rods are fixedly connected to the outside of the pressure relief pipe and pass through the side arc plate. The receiving box is fixedly connected to the outside of the pressure relief pipe. The end of the limiting rod away from the pressure relief pipe is fixedly connected to the inner wall of the receiving box. The compression spring is sleeved on the outside of the two sets of limiting rods. The two ends of the compression spring are fixedly connected between the side arc plate and the inner wall of the receiving box.

[0015] Optionally, the adjusting mechanism includes a screw and an internally threaded tube. The screw is fixed to one end of the metal rod two near the traction rope two, and the internally threaded tube is threaded to the outside of the screw. The traction rope two is fixed to the internally threaded tube.

[0016] Optionally, the edges of the first semicircular plate, the second semicircular plate, and the baffle are all made of rubber to increase sealing.

[0017] Optionally, the first and second traction ropes are aramid braided ropes.

[0018] Secondly, the present invention provides a green synthesis process for superhard materials, applied to an energy-saving high-voltage device for green synthesis of superhard materials as described in the first aspect. The process includes the following steps:

[0019] S1: When the hydraulic cylinder is running, it can drive the top hammer to move, thereby performing high-pressure synthesis on the sealing medium such as pyrophyllite. When the top hammer continues to squeeze the sealing medium such as pyrophyllite, the centrifugal locking mechanism is in a stationary state.

[0020] S2: When the sealing medium such as pyrophyllite suddenly breaks, the top hammer will move instantly under the action of inertia. At this time, the top hammer will drive the limit roller to rotate instantly through the metal rod and the traction rope. The instantaneous rotation of the limit roller will drive the centrifugal locking mechanism to run instantly.

[0021] S3: At this time, the centrifugal locking mechanism will quickly connect with the locking teeth and be blocked by the locking teeth, thus preventing it from continuing to operate. The limit roller will stop and cannot rotate under the action of the centrifugal locking mechanism. The stop of the limit roller will drive the top hammer to stop through the traction rope and the metal rod, thus preventing the top hammer from continuing to move and causing the top hammers to collide and "explode", resulting in damage.

[0022] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0023] This invention achieves instantaneous engagement between the centrifugal locking mechanism and the locking teeth through the structural design of the centrifugal locking mechanism. When the sealing medium such as pyrophyllite breaks, it quickly locks the inertial moving top hammer, effectively preventing impact damage caused by the uncontrolled displacement of the top hammer, preventing equipment "explosion" accidents from the root, and significantly improving the safety of equipment operation and the life of components.

[0024] Furthermore, through the structural design of the metal plate and friction teeth, the centrifugal engagement mechanism utilizes sparks generated by the friction between the metal plate and the friction teeth to ignite sodium azide, instantly generating inert nitrogen gas to accelerate the centrifugal engagement mechanism, improve the engagement response speed, effectively block the inertial displacement of the top hammer, avoid impact damage and the risk of equipment "explosion", and at the same time ensure the safety and non-toxicity of the gaseous products.

[0038] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1 and Figure 2 As shown, the present invention proposes a green energy-saving high-pressure device for the synthesis of superhard materials, comprising six sets of hinge beams 1 arranged in an up, down, left, right, front, and rear orientation. The six sets of hinge beams 1 are arranged in a "spherical" layout. Each set of hinge beams 1 has four sets of hinge ears 2 arranged in a circular array fixed to its outer side. Adjacent sets of hinge ears 2 are joined together, and the hinge ears 2 can connect the six sets of hinge beams 1 together. A pin is inserted into the two joined sets of hinge ears 2 to fix the hinge ears 2. Each set of hinge beams 1 has a hydraulic cylinder 3 installed inside, and a top hammer 4 is installed at one end of each hydraulic cylinder 3. When the hydraulic cylinder 3 is running, it can drive the top hammer 4 to move, thereby performing high-pressure synthesis of sealing media such as pyrophyllite. It should be noted that the hydraulic cylinder 3 and the top hammer 4 are existing technologies and are conventional technologies in hinged six-sided hydraulic presses, which will not be elaborated on further.

[0042] As one implementation method, such as Figure 3 - Figure 7 As shown, this embodiment also includes metal rods 5 fixed to the outside of multiple sets of top hammers 4. Only one set of metal rods 5 is shown in this embodiment, but it should be noted that each set of top hammers 4 has a metal rod 5 on its outside, along with other components that cooperate with the metal rod 5. When the hydraulic cylinder 3 drives the top hammers 4 to run smoothly, the metal rod 5 will move synchronously with the top hammers 4. A traction rope 6 is fixed to the end of the metal rod 5 away from the top hammers 4. The movement of the metal rod 5 will drive the traction rope 6 to move, applying a pulling force to the traction rope 6. A connecting rod 8 is fixed to the end of the hinge beam 1 away from the top hammers 4. A limit roller 7 is rotatably connected to the outside of the connecting rod 8, and the connecting rod 8 provides support for the limit roller 7. The end of the traction rope 6 away from the metal rod 5 is wrapped around the outside of the limiting roller 7. When the traction rope 6 is pulled by the metal rod 5, the traction rope 6 will drive the limiting roller 7 to rotate, thereby gradually releasing the length of the traction rope 6. A coil spring 9 is fixedly connected to the outside of the connecting rod 8. The end of the coil spring 9 away from the connecting rod 8 is fixedly connected to the bottom end of the limiting roller 7. When the limiting roller 7 rotates, the limiting roller 7 will also cooperate with the connecting rod 8 to drive the coil spring 9 to deform and generate elastic potential energy. When the hydraulic cylinder 3 drives the top hammer 4 to reset, the top hammer 4 simultaneously drives the metal rod 5 to reset. At this time, the coil spring 9 can release elastic potential energy, drive the limiting roller 7 to rotate in the opposite direction, and make the traction rope 6 wrap around the outside of the limiting roller 7 again.

[0043] Furthermore, such as Figure 5 , Figure 6 and Figure 7As shown, this embodiment also includes a collar 10 fixed to one end of the hinge beam 1 near the limiting roller 7. The hinge beam 1 supports the collar 10. Multiple sets of locking teeth 11 are fixed to the inner side of the collar 10. A centrifugal locking mechanism is provided at the top of the limiting roller 7, which cooperates with the locking teeth 11 to restrict the instantaneous movement of the top hammer 4. When the top hammer 4 continuously squeezes the sealing medium such as pyrophyllite, the centrifugal locking mechanism is in a stationary state. When the sealing medium such as pyrophyllite suddenly breaks, the top hammer 4 will move instantaneously under the action of inertia. At this time, the top hammer 4 will pass through Metal rod 5 and traction rope 6 drive the limiting roller 7 to rotate instantly. The instantaneous rotation of the limiting roller 7 will drive the centrifugal locking mechanism to operate instantly. At this time, the centrifugal locking mechanism will quickly connect with the locking tooth 11 and be blocked by the locking tooth 11, thus preventing it from continuing to operate. Under the action of the centrifugal locking mechanism, the limiting roller 7 will stop and cannot rotate. The stop of the limiting roller 7 will drive the top hammer 4 to stop through the traction rope 6 and metal rod 5, preventing the top hammer 4 from continuing to move, thereby preventing the top hammer 4 from colliding and "exploding" and causing damage.

[0044] Furthermore, such as Figure 6 and Figure 7 As shown, in this embodiment, the acceleration mechanism is connected to the centrifugal engaging mechanism to accelerate the speed at which the centrifugal engaging mechanism engages with the locking teeth 11. After the centrifugal engaging mechanism has traveled a certain distance, the acceleration mechanism will run instantly. The acceleration mechanism will fill the interior of the centrifugal engaging mechanism with gas, which will compress the air inside the centrifugal engaging mechanism, thereby accelerating the operation of the centrifugal engaging mechanism and accelerating the connection between the centrifugal engaging mechanism and the locking teeth 11. This will shorten the time required for the centrifugal engaging mechanism to restrict the movement of the top hammer 4 under the action of inertia.

[0045] Among them, such as Figure 5 , Figure 6 and Figure 7 As shown, the centrifugal locking mechanism includes a centrifuge tube 12, a gravity ball 13, a pressure plate 14, a support rod 15, a locking plate 16, a rotating shaft 17, and a compression spring 18. The centrifugal locking mechanism is described in detail below:

[0046] The centrifuge tube 12 is fixed to the top of the limiting roller 7. In the first state, when the limiting roller 7 rotates smoothly, it drives the centrifuge tube 12 to perform a smooth circular motion. The gravity ball 13 is located inside the centrifuge tube 12. Under the smooth circular motion of the centrifuge tube 12, it adheres to the pressure plate 14 and remains relatively stationary. In the second state, when the limiting roller 7 momentarily... Figure 6When the viewing angle rotates clockwise, the limiting roller 7 will momentarily drive the centrifuge tube 12 to move. Since the gravity ball 13 is not fixed to the centrifuge tube 12, the centrifuge tube 12 moves too fast, and the frictional force between the centrifuge tube 12 and the gravity ball 13 has too short an action time to break through the static friction impulse threshold. Therefore, the centrifuge tube 12 will not follow the gravity ball 13 in the same direction. The pressure plate 14 is slidably connected to the inner wall of the centrifuge tube 12, and under the inertia of the centrifuge tube 12, the gravity ball 13 will move towards... As the pressure plate 14 moves, the gravity ball 13 presses against it. The support rod 15 is fixed to the end of the pressure plate 14 away from the gravity ball 13, and extends through the centrifuge tube 12 to the outside of the tube. When the pressure plate 14 is pressed, it drives the support rod 15 to move. A clamping plate 16 is provided at the top of the limiting roller 7. A rotating shaft 17 is fixed inside the clamping plate 16 and rotatably connected to the top of the limiting roller 7. The support rod 15 is hinged to the clamping plate 16. The movement of plate 15 will cause plate 16 to swing along shaft 17, and shaft 17 will also rotate with plate 16 at the top of limiting roller 7. After plate 16 swings a certain distance, it will engage with tooth 11. At this time, tooth 11 and plate 16 are engaged together, and limiting roller 7 will not rotate, thus limiting the position of top hammer 4. The compression spring 18 is fixed between the inner wall of centrifuge tube 12 and pressure plate 14. When pressure plate 14 moves, pressure plate 14 will also squeeze compression spring 18, causing compression spring 18 to be compressed. When spring 18 deforms, it generates elastic potential energy. After the inertial action of the top hammer 4 ends, the limiting roller 7 is in a completely stationary state. The compressed spring 18 will release the elastic potential energy, thereby pulling the clamping plate 16 to swing back and reset, disengaging from the clamping tooth 11. It should be noted that the size of the centrifuge tube 12 and the gravity ball 13 can be determined according to the actual situation. The elastic potential energy of the compressed spring 18 can only pull the clamping plate 16 to reset and support the centrifuge tube 12 to run smoothly, driving the slight inertia generated by the gravity ball 13.

[0047] In addition, such as Figure 6 and Figure 7 As shown, the acceleration mechanism includes a sealed box 19, a metal elastic plate 20, and a gas delivery pipe 21. The acceleration mechanism is described in detail below:

[0048] The sealing box 19 is fixed to the top of the limiting roller 7, and the interior of the sealing box 19 is filled with sodium azide. The metal elastic plate 20 is fixed to the outside of the rotating shaft 17 inside the sealing box 19. When the clamping plate 16 swings and drives the rotating shaft 17 to rotate, the rotating shaft 17 will synchronously drive the metal elastic plate 20 to make a circular motion along the rotating shaft 17. After the rotating shaft 17 rotates a certain number of times, multiple sets of friction teeth are opened on the inner wall of the sealing box 19. The metal elastic plate 20 will contact the friction teeth, and the metal elastic plate 20 and the friction teeth will generate tiny sparks at this time. These sparks will ignite the sodium azide inside the sealing box 19. The reaction of the sodium azide... It should be completed within 30 milliseconds, generating a large amount of nitrogen gas. The two ends of the gas supply pipe 21 are respectively fixed inside the sealed box 19 and the centrifuge tube 12, and the end of the gas supply pipe 21 near the centrifuge tube 12 is located on the side of the pressure plate 14 near the gravity ball 13. The nitrogen gas will be quickly transmitted to the inside of the centrifuge tube 12 through the gas supply pipe 21. The gravity ball 13 and the pressure plate 14 inside the centrifuge tube 12 are then compressed by the nitrogen gas, which will accelerate the operation and increase the swing speed of the clamping plate 16. It should be noted that the gas generated by sodium azide is mainly inert nitrogen gas, which is non-toxic and non-flammable, meeting the extreme requirements of the safety device for instantaneous action.

[0049] Furthermore, such as Figure 7 As shown, the gravity ball 13 is spherical, and its diameter is matched to the inner wall of the centrifuge tube 12. This ensures that the gravity ball 13 will not wobble randomly inside the centrifuge tube 12 and can only move along a designated path. The inner wall of the centrifuge tube 12 and the pressure plate 14 are both made of rubber. The rubber material can prevent the pressure plate 14 from slightly moving inside the centrifuge tube 12 and generating sparks.

[0050] As one implementation method, such as Figure 8 - Figure 11As shown, a pressure relief pipe 22 is fixedly connected to the end of the hydraulic cylinder 3 away from the top hammer 4. A semi-circular plate 23 is fixedly connected to the inner wall of the pressure relief pipe 22, and a semi-circular plate 24 is slidably connected to the inner wall of the pressure relief pipe 22. In the initial state, the combined cross section of the semi-circular plate 23 and the semi-circular plate 24 is circular, and the liquid inside the hydraulic cylinder 3 cannot pass through the semi-circular plate 23 and the semi-circular plate 24. Two sets of limiting rods 25 are fixedly connected to the end of the semi-circular plate 24 away from the hydraulic cylinder 3. A horizontal plate 26 is fixedly connected to the end of the two sets of limiting rods 25 away from the semi-circular plate 24. A horizontal plate 27 is slidably connected to the outer side of the limiting rods 25. The horizontal plate 27 is fixedly connected to the semi-circular plate 23 and provides support for the limiting rods 25. Rod 25 supports the semicircular plate 24. Two sets of tension springs 28 are fixed between the horizontal plate 27 and the horizontal plate 26. A metal rod 29 is fixed to the outside of the metal rod 5. When the metal rod 5 moves, it will synchronously drive the metal rod 29 to move. A traction rope 30 is provided at the end of the metal rod 29 away from the metal rod 5. An adjustment mechanism is provided between the metal rod 29 and the traction rope 30. The adjustment mechanism is used to adjust the tension of the traction rope 30. The appropriate tension depends on the actual situation. Under normal conditions, when the top hammer 4 is used with high pressure pyrophyllite and other sealing media, the traction rope 30 will not be in a fully taut state. When the top hammer 4 suddenly shifts, it indicates that the sealing medium, such as pyrophyllite, has broken. The movement distance of metal rod 5 continues to increase, and traction rope 30 is taut. Metal rod 31 is fixed to the end of traction rope 30 away from metal rod 29. Traction rope 30 pulls metal rod 31. A blocking mechanism is provided around metal rod 31 to limit the displacement of semicircular plate 24. When metal rod 31 is subjected to force, it drives the blocking mechanism, which then stops limiting semicircular plate 24. The liquid inside pressure relief pipe 22 applies pressure to semicircular plate 24. Under this pressure, semicircular plate 24 moves limiting rod 25 along the interior of horizontal plate 27. Once the engagement between the semicircular plate 1 and semicircular plate 23 is complete, the liquid can pass through semicircular plate 24, thereby releasing the liquid pressure inside the hydraulic cylinder 3. This avoids excessive pressure, which could lead to increased wear on the clamping plate 16 and clamping teeth 11 during engagement, thus improving the service life of the device. Furthermore, when semicircular plate 24 moves the limiting rod 25, the limiting rod 25 also moves the horizontal plate 26. At this time, horizontal plate 26, in conjunction with horizontal plate 27, applies tension to the tension spring 28, causing it to deform and generate elastic potential energy. When the hydraulic cylinder 3 stops and the top hammer 4 resets, the tension spring 28 releases its elastic potential energy, pulling horizontal plate 26 to move in the opposite direction and reset. Horizontal plate 26 then moves semicircular plate 24 back to its original position via limiting rod 25.To re-engage semicircular plates 24 and 23, it should be noted that under normal operating conditions where hydraulic cylinder 3 does not add liquid to its inner cavity, the elastic potential energy released by the tension spring 28 is sufficient to pull the horizontal plate 26 back to its original position, ensuring the engagement of semicircular plates 24 and 23. However, when hydraulic cylinder 3 continuously adds liquid to its inner cavity, the pressure exerted by the liquid on semicircular plate 24 becomes too great for the tension spring 28 to overcome, causing deformation. Hydraulic cylinder 3 is existing and mature technology; it is a device that generates hydraulic potential energy by causing piston movement through the addition of liquid to its inner cavity.

[0051] Furthermore, such as Figure 9 and Figure 10 As shown, the blocking mechanism includes a side arc plate 32, a baffle 33, two sets of limiting rods 34, a receiving box 35, and a compression spring 36. The blocking mechanism is described in detail below:

[0052] The side arc plate 32 is fixedly connected to the metal rod 31. When the metal rod 31 moves, it pulls the side arc plate 32, causing it to move. The baffle 33 is fixedly connected to the end of the side arc plate 32 away from the metal rod 31. The baffle 33 passes through the pressure relief pipe 22 and is in contact with the semicircular plate 24. When the side arc plate 32 moves, it will drive the baffle 33 to move. In the initial state, the baffle 33 blocks the movement of the semicircular plate 24. When the baffle 33 moves, the movement of the semicircular plate 24 by the baffle 33 ends, and the semicircular plate 24 can then move. Both sets of limiting rods 34 are fixedly connected to the outside of the pressure relief pipe 22, and the limiting rods 34 pass through the side arc plate 32. When the side arc plate 32 moves, it will move along the outside of the limiting rods 34. The receiving box 35 Fixed to the outside of the pressure relief pipe 22, the end of the limiting rod 34 away from the pressure relief pipe 22 is fixed to the inner wall of the receiving box 35. The compression spring 36 is sleeved on the outside of the two sets of limiting rods 34. The two ends of the compression spring 36 are fixed between the side arc plate 32 and the inner wall of the receiving box 35. When the side arc plate 32 moves, it will cooperate with the receiving box 35 to squeeze the compression spring 36, causing the compression spring 36 to deform and generate elastic potential energy. When the metal rod 31 finishes pulling the side arc plate 32, the compression spring 36 will release the elastic potential energy and push the baffle 33 to reset through the side arc plate 32, so that the baffle 33 will block the movement path of the semicircular plate 24 again. It should be noted that the baffle 33 can only be reset after the semicircular plate 24 is reset.

[0053] Furthermore, such as Figure 11 As shown, the adjustment mechanism includes a screw 37 and an internally threaded tube 38. The adjustment mechanism is described in detail below:

[0054] The screw 37 is fixedly connected to one end of the metal rod 29 near the traction rope 30. The internally threaded tube 38 is threadedly connected to the outside of the screw 37. The traction rope 30 is fixedly connected to the internally threaded tube 38. When compressing sealing media such as pyrophyllite of different sizes, the traction rope 30 may need to be in different tension states in order to transmit pulling power to the metal rod 31 in a timely manner. In this embodiment, the internally threaded tube 38 can be rotated in different directions along the outside of the screw 37. When the internally threaded tube 38 is rotated in different directions, the length of the internally threaded tube 38 located outside the screw 37 can be adjusted, thereby adjusting the tension of the traction rope 30 to a suitable degree.

[0055] As one implementation method, such as Figure 10 As shown, the edges of the first semicircular plate 23, the second semicircular plate 24, and the baffle 33 are all made of rubber to increase sealing and prevent liquid from leaking along the gaps.

[0056] In addition, such as Figure 5 and Figure 8 As shown, the first traction rope 6 and the second traction rope 30 are aramid braided ropes, which are characterized by high temperature resistance and high tensile strength, and are suitable for the scenarios required in this embodiment.

[0057] A green synthesis process for superhard materials, comprising the following steps:

[0058] S1: When the hydraulic cylinder 3 is running, it can drive the top hammer 4 to move, thereby performing high-pressure synthesis on the sealing medium such as pyrophyllite. When the top hammer 4 continuously squeezes the sealing medium such as pyrophyllite, the centrifugal locking mechanism is in a stationary state.

[0059] S2: When the sealing medium such as pyrophyllite suddenly breaks, the top hammer 4 will move instantly under the action of inertia. At this time, the top hammer 4 will drive the limit roller 7 to rotate instantly through the metal rod 5 and the traction rope 6. The instantaneous rotation of the limit roller 7 will drive the centrifugal locking mechanism to run instantly.

[0060] S3: At this time, the centrifugal locking mechanism will quickly connect with the locking tooth 11 and be blocked by the locking tooth 11, thus preventing it from continuing to operate. The limiting roller 7 will be stationary and unable to rotate under the action of the centrifugal locking mechanism. When the limiting roller 7 is stationary, it will drive the top hammer 4 to stop through the traction rope 6 and the metal rod 5, thus preventing the top hammer 4 from continuing to move and causing it to collide and "explode," resulting in damage.

[0061] In this embodiment, the sealing medium, such as pyrophyllite, is placed at the center of the compression by multiple sets of top hammers 4. The hydraulic cylinder 3 is activated, causing the top hammers 4 to compress the sealing medium. When the hydraulic cylinder 3 drives the top hammers 4 smoothly, the metal rod 5 moves synchronously with them. This movement of the metal rod 5 causes the traction rope 6 to move, applying a pulling force. When the traction rope 6 is pulled by the metal rod 5, it drives the limiting roller 7 to rotate, gradually releasing the length of the traction rope 6. Furthermore, as the limiting roller 7 rotates, it also works with the connecting rod 8 to cause the coil spring 9 to deform, generating elastic potential energy. When the limiting roller 7 rotates smoothly, it drives the centrifuge tube 12 to perform a smooth circular motion, while the weight... The gravity ball 13 is located inside the centrifuge tube 12. Under the stable circular motion of the centrifuge tube 12, it adheres to the pressure plate 14 and remains relatively stationary. When the limiting roller 7 rotates instantaneously, it instantly moves the centrifuge tube 12. Since the gravity ball 13 is not fixed to the centrifuge tube 12, the frictional force between the centrifuge tube 12 and the gravity ball 13 is too short to exceed the static friction impulse threshold. Therefore, the centrifuge tube 12 will not follow the gravity ball 13 in the same direction. Furthermore, due to the inertia of the centrifuge tube 12, the gravity ball 13 moves towards the pressure plate 14. At this point, the gravity ball 13 presses against the pressure plate 14, and the pressure on the pressure plate 14 causes the support rod 15 to move. The movement causes the clamping plate 16 to swing along the rotating shaft 17, and the rotating shaft 17 will also rotate with the clamping plate 16 at the top of the limiting roller 7. After the clamping plate 16 swings a certain distance, it will engage with the clamping teeth 11. At this time, the clamping teeth 11 and the clamping plate 16 are engaged together, and the limiting roller 7 will not rotate, thus limiting the position of the top hammer 4. When the pressure plate 14 moves, the pressure plate 14 will also squeeze the compression spring 18, causing the compression spring 18 to deform and generate elastic potential energy. When the clamping plate 16 swings and drives the rotating shaft 17 to rotate, the rotating shaft 17 will synchronously drive the metal elastic plate 20 to make a circular motion along the rotating shaft 17. After the rotating shaft 17 rotates a certain number of times, the metal elastic plate 20 will contact the friction teeth, and the metal elastic plate 20 and the friction teeth will generate tiny sparks at this time. The sparks ignite the sodium azide inside the sealed box 19. The reaction of the sodium azide is completed within 30 milliseconds, generating a large amount of nitrogen gas. The nitrogen gas is then rapidly transported through the gas delivery pipe 21 to the centrifuge tube 12. The gravity ball 13 and pressure plate 14 inside the centrifuge tube 12 are compressed by the nitrogen gas, which accelerates their operation and increases the swing speed of the clamping plate 16. When the hydraulic cylinder 3 drives the top hammer 4 to reset, the top hammer 4 simultaneously drives the metal rod 5 to reset. At this time, the coil spring 9 can release its elastic potential energy, driving the limit roller 7 to rotate in the opposite direction, causing the traction rope 6 to wrap around the outside of the limit roller 7 again. After the inertial action of the top hammer 4 ends, the limit roller 7 is in a completely stationary state. The compression spring 18 will release its elastic potential energy, thereby pulling the clamping plate 16 to swing in the opposite direction and reset.Disengage from the engagement with the locking tooth 11;

[0062] Initially, the combined cross-section of semicircular plate 23 and semicircular plate 24 forms a circle, preventing the fluid inside hydraulic cylinder 3 from passing through them. When metal rod 5 moves, it synchronously drives metal rod 29 to move, allowing the internal threaded tube 38 to rotate in different directions along the outside of screw 37. This rotation adjusts the length of the internal threaded tube 38 outside screw 37, thereby adjusting the tension of traction rope 20. The movement of metal rod 29, in turn, drives traction rope 20 via screw 37 and internal threaded tube 38, allowing normal operation of the top hammer 4. When using high-pressure pyrophyllite and other sealing media, the second traction rope 30 will not be fully taut. When the top hammer 4 suddenly shifts, it indicates that the sealing media, such as pyrophyllite, has broken. The metal rod 5 then continues to move, and the second traction rope 30 remains taut. The second traction rope 30 will then pull the metal rod 31. As the metal rod 31 moves, it will pull the side arc plate 32, causing it to move. The movement of the side arc plate 32 will then drive the baffle 33 to move. Initially, the baffle 33 blocks the movement of the semicircular plate 24. After the baffle 33 moves, the movement of the semicircular plate 24 by the baffle 33 ends. 4. Movement can then occur, and the liquid inside the pressure relief pipe 22 will apply pressure to the semicircular plate 24. Under the pressure of the liquid, the semicircular plate 24 will drive the limiting rod 25 to move along the inside of the horizontal plate 27, ending the contact with the semicircular plate 23. The liquid can then pass through the semicircular plate 24, thereby releasing the liquid pressure inside the hydraulic cylinder 3. When the semicircular plate 24 drives the limiting rod 25 to move, the limiting rod 25 also drives the horizontal plate 26 to move. At this time, the horizontal plate 26, in conjunction with the horizontal plate 27, will apply tension to the tension spring 28, causing the tension spring 28 to deform and generate elastic potential energy. The side arc plate 32 also moves. The compression spring 36 is compressed by the receiving box 35, causing it to deform and generate elastic potential energy. When the hydraulic cylinder 3 stops and drives the top hammer 4 to reset, the tension spring 28 releases its elastic potential energy, pulling the horizontal plate 26 to move in the opposite direction and reset. The horizontal plate 26 then drives the semicircular plate 24 to reset through the limit rod 25, so that the semicircular plate 24 and the semicircular plate 23 are put together again. At this time, the metal rod 31 stops pulling the side arc plate 32, and the compression spring 36 releases its elastic potential energy, pushing the baffle 33 to reset through the side arc plate 32, so that the baffle 33 blocks the movement path of the semicircular plate 24 again.
