Description

Technical Field

[0001] This utility model relates to the technical field of equipment for synthesizing diamond using the high temperature and high pressure method, specifically to an equipment for synthesizing diamond using the high temperature and high pressure method. Background Technology

[0002] Based on the structural dimensions of the six-sided diamond press and the requirements of the diamond synthesis process, the diamond raw material blocks need to be heated and kept warm on a special heating device before being pressed on the six-sided diamond press. Moreover, the heated raw material blocks are transferred and conveyed over a long distance, which increases the contact time with media such as air and affects the temperature of the material, thereby affecting the quality of diamond synthesis. According to existing technology patents, such as the authorized announcement number CN113398846A, this invention relates to a high-temperature and high-pressure equipment for diamond forming, including a tungsten carbide platform for placing raw diamonds. The upper end of the tungsten carbide platform has a placement groove. The outer edge of the tungsten carbide platform is provided with a movable pick-and-place device. The pick-and-place device includes a pick-and-place rod. The front end of the pick-and-place rod is provided with a clamping cylinder for clamping the tungsten carbide platform and the raw diamond. The output end of the clamping cylinder is provided with two clamping blocks. The two clamping blocks are provided with a cooling device. This invention achieves the purpose of effectively improving the quality of the synthesized diamond by clamping and placing the tungsten carbide platform and the raw diamond through the movable pick-and-place device and automatically controlling the temperature during the diamond forming process through the cooling device. Based on existing patents, it can be concluded that after the diamond billet is preheated, a clamping mechanism is needed to hold the raw material and place it into a six-sided press for processing. Manual transfer is required. During the transfer process, the existing clamps are exposed structures. When clamping the diamond billet, the preheated diamond billet is exposed to the air, and heat is lost rapidly during the transfer process, affecting subsequent processing. Moreover, most of the existing clamps are clamping structures, which may cause accidental slippage during manual clamping and transfer. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a device for synthesizing diamond using a high-temperature and high-pressure method. This addresses the issue that when preheated diamond blanks are exposed to air, heat loss is rapid during transfer, affecting subsequent processing. Furthermore, existing clamps are mostly clamping structures, which can lead to accidental slippage during manual clamping and transfer.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for synthesizing diamond using a high-temperature and high-pressure method, comprising a heating furnace, a placement platform provided on the inner surface of the bottom of the heating furnace, a clamp slidably inserted into the inner end surface of one side of the heating furnace, the clamp comprising a loading clamp seat and a control frame, a recessed groove formed on the upper surface of the inner end of the loading clamp seat, a storage cavity formed on the inner surface of the loading clamp seat, the outer surface of the control frame slidably connected to the inner surface of the recessed groove of the loading clamp seat, a control slide rod fixedly installed on the outer end surface of one side of the control frame, and a support tube opening provided on the outer end surface of the loading clamp seat.

[0005] Preferably, the inner end outer surface of the control frame is provided with a threaded protrusion, and the inner end face of the control slide is provided with a threaded mounting groove, and the inner side surface of the inner end threaded mounting groove of the control slide is twisted and mounted on the outer surface of the threaded protrusion.

[0006] Preferably, the upper inner surface of the control frame is provided with a positioning protrusion, which protrudes upward and the height of the positioning protrusion is greater than the overall height of the control frame.

[0007] Preferably, both the recessed groove and the storage cavity adopt a square groove structure, and the recessed groove and the storage cavity are interconnected.

[0008] Preferably, the loading clamp and control frame are made of high-temperature resistant ceramic, and the support pipe and loading clamp are an integral design structure, with the support pipe also being made of high-temperature resistant ceramic.

[0009] Preferably, the heating furnace has a feed inlet on its side, the filling clamp is inserted into the heating furnace along the feed inlet, the bottom of the filling clamp is supported on the upper surface of the placement platform, and the inner end face of the filling clamp has a rounded corner.

[0010] Preferably, a positioning bolt is provided on the upper surface of the outer end of the filling clamp, and a threaded groove is provided on the upper surface of the filling clamp. The positioning bolt is installed on the inner surface of the threaded groove of the filling clamp, and the outer surface of the hexagonal platform of the positioning bolt is attached to and supported on the outer surface of the heating furnace.

[0011] Compared with the prior art, this utility model provides a device for synthesizing diamond using a high-temperature and high-pressure method, which has the following beneficial effects: By adopting an insert-type clamp structure design, the diamond billet is directly fed into the heating furnace for heating through the clamp. After heating, it is put into the storage cavity through the control frame and directly pulled out for transfer. The diamond billet does not come into contact with the outside world in the storage cavity. The outside is insulated by the filling clamp and the control frame, which makes it difficult for heat to escape and avoids rapid heat loss. This ensures the temperature of the diamond during transfer after preheating. With the storage structure and the outer closed structure, the diamond billet will not fall due to human error.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides a technical solution: a device for synthesizing diamond using a high-temperature and high-pressure method, according to the appendix. Figure 1-4 As shown, the device includes a heating furnace 1. A placement platform 2 is provided on the inner surface of the bottom of the heating furnace 1. A clamp is slidably inserted into the inner surface of one side of the heating furnace 1. The clamp includes a loading clamp 3 and a control frame 4. A recessed groove 30 is formed on the upper inner surface of the loading clamp 3, and a storage cavity 31 is formed on the inner surface of the loading clamp 3. The outer surface of the control frame 4 is slidably connected to the inner surface of the recessed groove 30 of the loading clamp 3. A control slide rod 5 is fixedly installed on the outer surface of one side of the control frame 4, and a support pipe opening 6 is provided on the outer surface of the loading clamp 3. By adopting an insert-type clamp structure design, the diamond billet is directly fed into the heating furnace 1 for heating through the clamp. After heating, it is put into the storage cavity 31 through the control frame 4 and directly pulled out for transfer. The diamond billet does not come into contact with the outside world in the storage cavity 31. The outside is insulated by the filling clamp 3 and the control frame 4, so the heat is not easily lost and the rapid loss of heat is avoided. This ensures that the temperature of the diamond does not drop when it is transferred after preheating. With the storage structure and the closed structure on the outside, the diamond billet will not fall due to human operation error. The inner end of the control frame 4 is provided with a threaded protrusion 41, and the inner end face of the control slide rod 5 is provided with a threaded mounting groove. The inner side surface of the threaded mounting groove of the inner end of the control slide rod 5 is twisted and installed on the outer surface of the threaded protrusion 41. During installation, the control slide rod 5 is inserted along the support tube opening 6. At this time, the threaded mounting groove reaches the threaded protrusion 41 of the control frame 4. Twisting the control slide rod 5 can install the threaded mounting groove and the threaded protrusion 41. The installation parts are convenient. When disassembling, the control slide rod 5 can be twisted in the opposite direction to remove it. It is convenient and flexible to use. The upper inner surface of the control frame 4 is provided with a positioning protrusion 40. The positioning protrusion 40 protrudes upward and the height of the positioning protrusion 40 is greater than the overall height of the control frame 4. The positioning protrusion 40 is used to seal the outside of the storage cavity 31 after the sliding control frame 4 is introduced into the storage cavity 31, so as to prevent airflow from entering and causing the diamond billet to cool down. Both the recessed groove 30 and the storage cavity 31 adopt a square groove structure, and the recessed groove 30 and the storage cavity 31 are interconnected; this facilitates the insertion of the control box 4 from the recessed groove 30 into the storage cavity 31. The loading clamp 3 and the control frame 4 are made of high-temperature resistant ceramic. The support port 6 and the loading clamp 3 are an integral design structure. The support port 6 is also made of high-temperature resistant ceramic. It can be heated together with the diamond billet. The ceramic has high-temperature resistance. The clamp made of high-temperature resistant ceramic is easy to use. It can be directly inserted into the heating furnace and the diamond billet can be directly introduced into the heating furnace 1. A feed inlet 100 is provided on the side of the heating furnace 1. The filling clamp 3 is inserted into the heating furnace 1 along the feed inlet 100, and the bottom of the filling clamp 3 is supported on the upper surface of the placement platform 2. A rounded corner is provided on the inner end face of the filling clamp 3. The rounded corner structure is used to guide the filling clamp 3 to slide in when it is inserted along the feed inlet 100, so that the filling clamp 3 can be easily inserted. A positioning bolt 7 is provided on the upper surface of the outer end of the filling clamp 3. A threaded groove is provided on the upper surface of the filling clamp 3. The positioning bolt 7 is installed on the inner surface of the threaded groove of the filling clamp 3. The outer surface of the hexagonal platform of the positioning bolt 7 is attached to and supported on the outer surface of the heating furnace 1. The positioning bolt 7 can be used to position the filling clamp 3 when it is inserted into the heating furnace 1. It can be placed against the outside of the heating furnace 1 to avoid excessive insertion. The working principle of this device is as follows: During use, the clamp includes a loading clamp 3 and a control frame 4. The upper inner surface of the loading clamp 3 has a recessed groove 30, and the inner side surface of the loading clamp 3 has a storage cavity 31. The outer surface of the control frame 4 is slidably connected to the inner side surface of the recessed groove 30 of the loading clamp 3. The diamond billet is placed in the control frame 4 within the recessed groove 30. The loading clamp 3 is inserted into the heating furnace 1, and its bottom can be supported on the surface of the placement platform 2. Because the loading clamp 3 and control frame 4 are made of high-temperature resistant ceramic, and the support pipe 6 is an integral design with the loading clamp 3, also made of high-temperature resistant ceramic, it can be heated along with the diamond billet. The ceramic has high-temperature resistance, and the clamp made of high-temperature resistant ceramic is easy to use; it can be directly inserted into the heating furnace 1, and the diamond billet can be directly introduced into the heating furnace 1. After heating in the heating furnace 1… At this point, pulling the control lever 5 outward will cause the control frame 4 to slide outward, pulling the diamond billet into the storage cavity 31. The upper inner surface of the control frame 4 is provided with a positioning protrusion 40, which protrudes upward and is higher than the overall height of the control frame 4. The positioning protrusion 40 is used to seal the outside of the storage cavity 31 after the control frame 4 is slid in, preventing airflow from entering and causing the diamond billet to cool. Then, the loading clamp 3 is pulled out through the support pipe 6. During transfer, because the diamond billet is stored in the storage cavity 31 and sealed externally by the loading clamp 3 and the control frame 4, the diamond billet is insulated from heat, preventing heat loss during transfer (operators can wear heat-resistant gloves or use heat-resistant tools during operation). Furthermore, when transferring to the six-sided top press, the clamp is flipped, that is, the loading clamp 3 is flipped, the recessed groove 30 is flipped downward, and when the control slide 5 is pushed, the control frame 4 can be driven to push out the diamond billet. The diamond billet can be discharged downward, which is convenient to take out; the operation is convenient.
