Description

Technical Field

[0001] This invention relates to the field of diamond processing technology, and in particular to a diamond synthesis apparatus and a method for processing high-hardness diamonds. Background Technology

[0002] During diamond processing, a block-shaped pyrophyllite is wrapped around the outermost part of the raw material and placed in the center of a six-sided press to serve as a high-temperature and high-pressure conduction and insulation medium. The six ends of the six-sided press apply pressure to the six sides of the block-shaped pyrophyllite simultaneously to form a closed high-pressure synthesis chamber.

[0003] After multiple diamond blank sintering operations, the central area of ​​the press is prone to residual impurities such as pyrophyllite fragments, blank processing waste, high-temperature carbonization products, and metal catalyst overflows. Due to gravity deposition, especially at the lower end, residues tend to accumulate and adhere, gradually hardening to form a stubborn scale layer. Traditional technology usually uses pneumatic suction to clean the residues. However, due to the large number of cavities, thin walls, and narrow exhaust channels during multi-cavity synthesis, the amount of residue generated is greater and the adhesion is stronger. Simple pneumatic blowing can only remove loose dust on the surface and is difficult to effectively remove the already adhered and hardened residues. The cleaning efficiency needs to be improved.

[0004] Therefore, it is necessary to propose a diamond synthesis device and a method for processing high-hardness diamonds to solve the above problems. Summary of the Invention

S3, Break up: Control the telescopic cylinder to move down, switch the swing cylinder to a vertical position, and the cleaning roller extends into the collection trough to break up the blocky residue.

[0016] The technical effects and advantages of this invention are as follows: 1.

[0033] This invention provides, for example Figures 1-15The diamond synthesis apparatus shown includes six sets of pressure components 2 mounted on a base 1. These six pressure components 2 correspond to six pressure directions: up / down, left / right, and forward / backward. A control system (including a PLC controller, pressure sensors, displacement sensors, and a hydraulic drive module, enabling closed-loop pressure control and pressure holding lock) drives the apparatus to achieve synchronous feeding and pressure holding. Each pressure component 2 includes an end 201 and an electric cylinder 202. The electric cylinder 202 is mounted on the base 1, and the end 201 is fixed to the extension / retraction end of the electric cylinder 202. In the actual processing, the diamond carbon source, catalyst sheet and seed crystal are arranged in layers according to the multi-cavity synthesis structure, and then the whole assembly is put into the pyrophyllite synthesis cavity to obtain the assembly. Then the assembly is placed in the center of the six pressure components 2, and the six ends 201 apply pressure to the six sides of the assembly simultaneously, so that the pyrophyllite undergoes plastic flow under high temperature and high pressure and forms a closed cavity, providing a stable temperature field and pressure field for diamond crystal growth, thereby preparing high hardness diamond. Diamond and its manufacturing are common existing technologies, and will not be described in detail here.

[0034] After multiple diamond synthesis operations, impurities such as pyrophyllite fragments, blank processing waste, high-temperature carbonization products, and metal catalyst overflows are easily retained in the central part. Due to gravity deposition, especially at the lower end 201, residues tend to accumulate and adhere, gradually hardening to form a stubborn scale layer. Furthermore, due to the large number of cavities, thin walls, and narrow exhaust channels during multi-cavity synthesis, the amount of residue generated is greater and its adhesion is stronger. Simple pneumatic suction can only remove loose surface dust and is difficult to effectively remove the already adhered and hardened residues. Therefore, this invention provides a cleaning mechanism at the lower pressure component 2. On the one hand, it pushes and scrapes off the stubborn residues at the top of the lower end 201, and simultaneously completes dust suction and directional collection of blocky residues. On the other hand, it crushes and disperses the collected blocky residues and removes them, achieving integrated and efficient cleaning of pushing and scraping cleaning, crushing and anti-clogging, dust suppression, and complete residue collection. This ensures the cleanliness of the working surface of the end 201, improves the stability of diamond synthesis, and extends the service life of the equipment.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the cleaning mechanism includes a ring frame 3 sleeved on the outside of the end 201. A vertical rod 27 is fixedly connected to the bottom of the ring frame 3, and the bottom of the vertical rod 27 is fixedly connected to the base 1. The position of the ring frame 3 is fixed by the vertical rod 27. A ring frame 4 is rotatably set on the outside of the ring frame 3. The ring frame 3 and the ring frame 4 together form a collection trough 5 with an open top, which is used to automatically collect and store the blocky residue that falls during the operation. A side plate 6 is integrally fixed on the outer wall of the ring frame 4. A sliding channel 601 is opened on the side plate 6. A side groove 301 is opened on the side wall of the ring frame 4. The side groove 301 is connected to the sliding channel 601. A telescopic cylinder 7 is slidably set inside the sliding channel 601. Both the upper and lower ends of the telescopic cylinder 7 are designed to be open, and the bottom end of the telescopic cylinder 7 is connected to the negative pressure suction pipe of the factory through a telescopic hose.

[0036] A hinge plate 701 is fixedly connected to the top of the telescopic cylinder 7. A swing cylinder 8 is hinged to the top of the hinge plate 701 via a hinge shaft. The swing cylinder 8 has an opening on the side near the ring frame 4. A torsion spring 9 is fitted on the hinge shaft. One end of the torsion spring 9 is fixedly connected to the hinge plate 701, and the other end of the torsion spring 9 is fixedly connected to the inner wall of the swing cylinder 8. When no other external force is applied, the elastic support force of the torsion spring 9 causes the swing cylinder 8 to swing to a horizontal position and form an L-shape with the telescopic cylinder 7. An elastic cylinder 10 is fixedly connected between the top of the telescopic cylinder 7 and the bottom of the swing cylinder 8. The elastic cylinder 10 is made of high-temperature resistant rubber material and can adapt to the swing of the swing cylinder 8 to maintain communication between the telescopic cylinder 7 and the swing cylinder 8.

[0037] A support plate 11 is fixedly connected to the top of the swing cylinder 8. A cleaning roller 12 is rotatably mounted on the support plate 11. The cleaning roller 12 is distributed along the height direction of the swing cylinder 8. The cleaning roller 12 is close to the side wall opening of the swing cylinder 8 to achieve follow-type suction. Multiple sets of hard and wear-resistant blades are assembled on the outer side of the cleaning roller 12. The outer edge of the blade is provided with an arc transition structure, which can both push and scrape off stubborn residues on the working surface of the end 201, and also break up blocky residues into debris, without damaging the working surface of the end 201. A rotating shaft 13 is rotatably mounted at the top of the swing cylinder 8. The rotating shaft 13 rotates synchronously with the cleaning roller 12. The bottom end of the rotating shaft 13 extends to the bottom end of the swing cylinder 8 and is fixedly mounted with a fan 17. Driven by the external negative pressure suction airflow, the fan 17 is passively rotated to drive the rotating shaft 13 to rotate, and the cleaning roller 12 rotates synchronously, realizing rotation cleaning and suction at the same time. The external negative pressure suction is large, ensuring the stable rotation of the cleaning roller 12.

[0038] The actual working conditions are as follows: In the first stage, the telescopic cylinder 7 is controlled to move downward, so that the swing cylinder 8 is vertical and its lower half is retracted into the sliding channel 601. At this time, the top height of the swing cylinder 8 is at a moderate position and will not interfere with the normal feeding and pressing of the pressure component 2 and the high temperature and high pressure synthesis operation.

[0039] In the second stage, after the synthesis operation is completed, the six pressure components 2 retract and reset synchronously. The lower end 201 moves downward, and at this time, some residues fall off naturally due to gravity and fall into the collection tank 5.

[0040] Control the telescopic cylinder 7 to move upward (refer to) Figure 14 and Figure 15 Until the bottom end of the swing cylinder 8 extends out of the sliding channel 601, under the elastic support of the torsion spring 9, the swing cylinder 8 swings to a horizontal position and is distributed in an L-shape with the telescopic cylinder 7. At this time, the cleaning roller 12 is attached to the top working surface of the end 201; the control ring frame 4 rotates outside the ring frame 3, and the ring frame 4 drives the telescopic cylinder 7, the swing cylinder 8 and the cleaning roller 12 to revolve synchronously. The cleaning roller 12 is attached to the top of the end 201 and rotates at a uniform speed to push and scrape, peeling off the stubborn residue, and the blocky residue falls into the collection tank 5.

[0041] Next, the control ring frame 4 rotates in the opposite direction outside the ring frame 3, and performs suction operation through the telescopic cylinder 7 and the swing cylinder 8. When subjected to the suction airflow, the fan 17 is passively rotated, driving the rotating shaft 13 to rotate, and the cleaning roller 12 rotates synchronously to remove the dust generated during the scraping operation in a timely manner. At the same time, the rotation of the cleaning roller 12 and its revolution around the ring frame 4 are coordinated to achieve dynamic cleaning operation and ensure cleaning effect. In addition, the cleaning roller 12 drives the outer blades to rotate synchronously with its rotation. By changing the angle of the blades, the suction airflow can be guided, and the negative pressure adsorption flow direction can be flexibly adjusted. The airflow adsorption direction can be changed at multiple angles, effectively expanding the suction coverage of dust and fine residue.

[0042] In addition, the rotating design of the cleaning roller 12 allows its outer wall blades to periodically approach the suction port on the side of the swing cylinder 8. Fine dust and tiny residues attached to the blade surface can be promptly adsorbed and removed by the negative pressure airflow, avoiding long-term accumulation and adhesion of residues that affect the scraping effect and improving cleaning efficiency.

[0043] In the third stage, control the telescopic cylinder 7 to move downwards (refer to...). Figure 12 and Figure 13 This causes the swing cylinder 8 to be vertical, with its lower half retracted into the sliding channel 601. At this time, the bottom end of the cleaning roller 12 extends into the collection trough 5. The control ring frame 4 rotates outside the ring frame 3, and negative pressure suction is performed through the telescopic cylinder 7 and the swing cylinder 8. Under the action of the suction airflow, the fan 17 is passively rotated, driving the rotating shaft 13 and the cleaning roller 12 to rotate. The rotation and revolution of the cleaning roller 12 work together to break up the blocky residue in the collection trough 5, forming debris. After being broken up, the debris is promptly sucked out through the side opening of the swing cylinder 8 and the side groove 301. Compared with directly sucking up blocky residue, this can effectively avoid the blockage of the suction pipeline.

[0044] In summary, by setting up structures such as the ring frame 3 and the ring frame 4, and by using the attitude switching and following suction of the cleaning roller 12, this invention can effectively remove stubborn residues from the working surface of the end 201, while also centrally dispersing the fallen blocky residues to prevent dust. It is suitable for the needs of multi-cavity diamond synthesis processing and improves processing efficiency.

[0045] At the same time, relying on the suction airflow to drive the fan 17 to rotate passively, and in conjunction with the revolution of the ring frame 4, a composite dynamic cleaning is formed, which expands the suction coverage area. Combined with the pushing, scraping and scattering processes, various residues and dust are removed in time to ensure the cleaning effect.

[0046] Reference Figure 2 , Figure 9 , Figure 10 and Figure 12 , Figure 13 As shown, an elastic plate 19 is provided on the side of the swing cylinder 8 facing away from the collection tank 5, and the elastic plate 19 is distributed correspondingly to the bottom end of the opening on the side wall of the swing cylinder 8. The elastic plate 19 is located above the fan 17. The elastic plate 19 is made of wear-resistant rubber material. A magnetic block 20 is fixedly embedded on the side of the elastic plate 19 facing away from the collection tank 5. A through groove is opened on the side plate 6, and an electromagnet 21 is fixedly installed inside the through groove. The magnetic block 20 cooperates with the electromagnet 21. A shaft groove 1301 is opened on the outer wall of the rotating shaft 13. The shaft groove 1301 is distributed correspondingly to the elastic plate 19. Multiple shaft grooves 1301 are provided. Multiple shaft grooves 1301 are evenly distributed around the outer wall of the rotating shaft 13. A brake block 1901 is fixed on the side of the elastic plate 19 near the rotating shaft 13. The brake block 1901 is engaged with the shaft groove 1301.

[0047] After the dispersion is completed, the electromagnet 21 is activated, and the magnets on the side of the magnetic block 20 and the electromagnet 21 that are close to each other are of the same magnetic polarity. Under the action of the repulsive force between the two, the elastic sheet 19 is squeezed and bulges into the swing cylinder 8. The brake block 1901 is engaged in the corresponding shaft groove 1301, so that the rotating shaft 13 and the fan 17 can no longer rotate, and the cleaning roller 12 stops operating at the same time. At this time, only the negative pressure suction operation is performed. At the same time, due to the blocking and limiting effect formed by the bulging of the elastic sheet 19, the suction force is concentrated at the bottom of the opening on the side wall of the swing cylinder 8, ensuring that the fine residue in the collection tank 5 can be efficiently gathered and sucked up, avoiding the problems of residue residue and insufficient local suction force.

[0048] In addition, during the dispersing process, the elastic sheet 19 can be controlled to be squeezed and bulge into the swing cylinder 8, and the brake block 1901 does not contact the shaft groove 1301, thereby reducing the suction flow cross-sectional area, accelerating the airflow rate, thereby increasing the passive rotation speed of the fan 17, which in turn drives the cleaning roller 12 to operate at a higher speed, enhancing the dispersing effect on blocky residues, and simultaneously removing floating dust and debris more quickly, further improving the overall cleaning efficiency.

[0049] In summary, by setting up structures such as the elastic sheet 19, the magnetic block 20 and the electromagnet 21, the fan 17 and the cleaning roller 12 can be stopped quickly, and the two working modes of cleaning debris and pure suction can be flexibly switched. Moreover, after the elastic sheet 19 bulges inward, it can change the direction of the suction airflow of the swing cylinder 8, and concentrate the negative pressure suction force to the collection tank 5, thereby improving the residue cleaning effect.

[0050] Reference Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 11 As shown, in order to realize the vertical movement of structures such as telescopic cylinder 7 and swing cylinder 8, an electric push rod 18 is provided on the side of the side plate 6. The fixed end of the electric push rod 18 is installed on the side wall of the side plate 6, and the telescopic end of the electric push rod 18 is installed on the bottom end of the side wall of the telescopic cylinder 7. The telescopic movement of the electric push rod 18 is used to drive the telescopic cylinder 7 and swing cylinder 8 to move vertically.

[0051] A guide frame 26 is fixedly installed on the top of the side plate 6. The guide frame 26 is vertically distributed and has a guide slope 2601 at the top. The top of the guide slope 2601 is inclined towards the ring frame 4. An inner groove 602 is opened on the inner wall of the sliding channel 601. The inner groove 602 is distributed correspondingly to the guide frame 26. At the same time, a guide block 801 is fixedly connected to the bottom of the side wall of the swing cylinder 8. The guide block 801 is located above the connection between the hinge plate 701 and the swing cylinder 8. The guide block 801 abuts against the guide slope 2601.

[0052] Specifically, the swing cylinder 8 extends from the sliding channel 601 at its bottom end. Under the elastic support of the torsion spring 9, when the swing cylinder 8 swings to form an L-shape with the telescopic cylinder 7, the guide block 801 passes through the inner groove 602, the side wall of the guide frame 26, and the guide slope 2601 in sequence, and finally abuts against the top of the guide slope 2601. When the telescopic cylinder 7 is controlled to move downward so that the swing cylinder 8 is vertical, guided by the guide slope 2601, the swing cylinder 8 gradually returns from a horizontal position to a vertical position. The guide block 801 passes through the guide slope 2601, the side wall of the guide frame 26, and the inner groove 602 in sequence, and finally abuts against the bottom of the inner groove 602. In actual operation, the operator can also assist the telescopic cylinder 7 in switching states and adjust according to the specific usage.

[0053] Reference Figure 5 and Figure 6As shown, in order to enable the ring frame 4 to rotate outside the ring frame 3, a drive assembly is provided between the ring frame 3 and the ring frame 4. The drive assembly includes a motor 22, a gear 23, a gear ring 24, and a mounting bracket. The mounting bracket is fixed to the bottom of the ring frame 3, the motor 22 is mounted on the mounting bracket, the gear 23 is fixedly connected to the drive shaft of the motor 22, and the gear ring 24 is fixedly connected to the inner wall of the ring frame 4. The gear 23 and the gear ring 24 are meshed together. In actual use, the motor 22 drives the gear 23 to rotate. Since the gear 23 and the gear ring 24 are meshed together, the ring frame 4 rotates outside the ring frame 3, and drives the telescopic cylinder 7, the swing cylinder 8, and other structures to rotate synchronously.

[0054] Reference Figure 3 , Figure 4 and Figure 8 As shown, a transmission assembly is provided between the cleaning roller 12 and the rotating shaft 13. The transmission assembly includes a first pulley 14, a second pulley 15, and a belt 16. The first pulley 14 is fixedly installed on the top of the cleaning roller 12, and the second pulley 15 is fixedly installed on the top of the rotating shaft 13. The first pulley 14 and the second pulley 15 are connected by the belt 16. In actual use, when subjected to the suction airflow, the fan 17 is passively rotated, driving the rotating shaft 13 to rotate. The second pulley 15 rotates synchronously. Since the first pulley 14 and the second pulley 15 are connected by the belt 16, the first pulley 14 drives the cleaning roller 12 to rotate. A dust cover (not shown in the figure) is provided on the outside of the transmission assembly to prevent the first pulley 14, the second pulley 15, and the belt 16 from being affected by dust.

[0055] Reference Figure 1 and Figure 2 As shown, a top cover 25 is fixedly connected to the top of the ring frame 3. The top cover 25 surrounds the outside of the telescopic end of the electric cylinder 202. Both the end 201 and the telescopic end of the electric cylinder 202 can slide inside the top of the top cover 25. The top cover 25 is flared, narrow at the top and wide at the bottom. The inclined inner wall of the top cover 25 accurately guides the residue falling from the surface of the end 201 into the collection tank 5.

S3, Disperse: Control the telescopic cylinder 7 to move down, switch the swing cylinder 8 to a vertical position, and the cleaning roller 12 extends into the collection trough 5 to disperse the blocky residue.
