Description

Technical Field

[0001] This utility model relates to the field of ultra-high pressure components technology, and in particular to an ultra-high pressure hard alloy anvil. Background Technology

[0002] In the field of ultra-high pressure, anvils are the core components for constructing ultra-high pressure environments. Traditional anvils have many shortcomings. On the one hand, some anvil structures are poorly designed, resulting in uneven stress distribution under ultra-high pressure, which can easily lead to localized damage and shorten the service life of the anvil.

[0003] On the other hand, some anvils have poor compatibility with supporting equipment, making it difficult to maintain a stable ultra-high pressure environment for a long time, which affects the accuracy and reliability of experiments or synthesis. Therefore, we propose an ultra-high pressure cemented carbide anvil to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to solve the problems of uneven stress distribution, easy damage, and poor adaptability of traditional anvils that affect experimental reliability, and to propose an ultra-high pressure hard alloy anvil.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultra-high pressure cemented carbide anvil includes an anvil body, which is cylindrical. The top of the anvil body has a top surface, and multiple edges are evenly spaced on the anvil body. A docking base is fixedly connected to the bottom of the anvil body. The multiple edges and the top surface form a multi-faceted structure, wherein the angle between the edges and the top surface is 41.5°, the size of the top surface is 41mm × 41mm, the height from the bottom surface to the top surface of the anvil body is 97mm, and the diameter of the anvil body is 130mm.

[0007] By utilizing the multi-faceted structure and the specific angles and dimensions, the stress distribution under ultra-high pressure is optimized, stress concentration is reduced, and the compressive strength and service life of the anvil are improved.

[0008] In one possible design, the docking base is a shell structure with an installation mechanism inside. The bottom of the installation mechanism extends to the bottom of the docking base for connection with external ultra-high voltage equipment.

[0009] The installation mechanism includes a support tray that contacts the bottom of the docking base, and a clamping assembly is provided on the top of the support tray, the top of which extends into the docking base.

[0010] An inner inclined ring is fixedly connected to the inner wall of the docking base, and the clamping assembly is in a transmission engagement with the inner inclined ring.

[0011] A clamping and positioning ring is fixedly connected to the top inner wall of the docking base, and the clamping assembly clamps the clamping and positioning ring.

[0012] In one possible design, the clamping assembly includes a mounting retaining ring fixedly connected to the top of the support tray, the mounting retaining ring being located within the docking base;

[0013] Multiple ball-head connecting rods are slidably connected at equal intervals through the inner wall of the assembly fixing ring. One end of each ball-head connecting rod is provided with a ball head, which engages with the inclined surface and straight surface of the inner wall of the inner inclined ring. The other end of each ball-head connecting rod is fixedly connected to a clamping fixing plate, which clamps the clamping positioning ring.

[0014] In one possible design, a tension spring is fitted on the ball joint connecting rod and located inside the assembly fixing ring. The two ends of the tension spring are respectively fixedly connected to the inner wall of one side of the ball joint connecting rod and the assembly fixing ring via hooks.

[0015] When the clamping fixing plate clamps the clamping positioning ring, the tension spring is stretched and under force.

[0016] In one possible design, a conical clamping chuck located within the clamping and positioning ring is fixedly connected to the top inner wall of the docking base;

[0017] A rotating transmission rod is rotatably connected through the carrying tray, and a docking protective cover is fixedly connected to the top of the rotating transmission rod. The conical clamping chuck is located inside the docking protective cover.

[0018] Both sides of the docking protective cover are fixedly connected to support positioning rings, and the top of the support positioning rings is slidably connected to inclined locking plates. Both inclined locking plates are in contact with the top of the conical clamping chuck.

[0019] An arc-shaped elastic support plate is fixedly connected to one side of the inner wall of the support positioning ring. The top of the arc-shaped elastic support plate extends above the support positioning ring and is fixedly connected to one side of the inclined locking plate. An auxiliary elastic support plate is fixedly connected inside the arc-shaped elastic support plate.

[0020] In one possible design, the conical clamping chuck has two symmetrically formed exit guide grooves;

[0021] A torsion spring is fitted onto the rotating transmission rod and located below the support tray. The two ends of the torsion spring are fixedly connected to the bottom of the support tray and the rotating transmission rod respectively by hooks.

[0022] In one possible design, the bottom of the load-bearing tray is symmetrically and fixedly connected to two fixed support frames, which are used to connect to external ultra-high voltage equipment.

[0023] In one possible design, the anvil body is made of a cemented carbide material.

[0024] In one possible design, the number of edges is four.

[0025] Beneficial effects:

[0026] 1. Optimized stress distribution: The unique structure combining the top of the multi-faceted frustum with the docking base effectively improves the stress distribution under ultra-high pressure, reduces stress concentration, significantly improves the high pressure resistance of the anvil, and extends its service life;

[0027] 2. Excellent adaptability: The structural design is highly compatible with ultra-high pressure equipment, enabling it to work stably for extended periods under ultra-high pressure conditions, ensuring the smooth progress of experiments or synthesis processes and improving the accuracy and reliability of results;

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] In one embodiment: Refer to Figure 1-5 An ultra-high pressure cemented carbide anvil includes an anvil body 1, which is cylindrical in shape. A top surface 3 is provided on the top of the anvil body 1, and multiple angles 2 are evenly spaced along the circumference of the anvil body 1. A docking base 4 is fixed to the bottom of the anvil body 1. The multiple angles 2 and the top surface 3 together form a multi-faceted structure, wherein the included angle between the angles 2 and the top surface 3 is precisely set to 41.5°, the dimensions of the top surface 3 are 41mm × 41mm, and the height from the bottom surface of the anvil body 1 to the top surface 3 is 97mm.

[0037] The angle between the edge 2 and the top surface 3 can be between 36° and 41°, the side length of the top surface 3 is between 40.5mm and 41.5mm, the diameter of the anvil body 1 is between 129.5mm and 130.5mm, and the height from the bottom surface of the anvil body 1 to the top surface 3 is between 96.5mm and 97.5mm.

[0038] This application can be used in the field of ultra-high voltage components technology, or in other fields applicable to this application.

[0039] In another embodiment: Reference Figure 2-5Based on the above embodiments, the following improvements are made: An installation mechanism for positioning the anvil body 1 is further provided on the ultra-high pressure hard alloy anvil. The docking base 4 is a shell structure, and the installation mechanism is located inside the docking base 4. The bottom of the installation mechanism extends below the docking base 4 for connection to external ultra-high pressure equipment. The installation mechanism includes a support tray 5 located below the docking base 4, which contacts the bottom of the docking base 4. A clamping assembly is provided on the top of the support tray 5, with its top extending into the docking base 4. An inner tilting ring 6 is fixedly installed on the inner wall of the docking base 4, and the clamping assembly cooperates with the inner tilting ring 6. When assembling the docking base 4 and the support tray 5, the support tray 5 is brought close to the docking base 4, causing the clamping assembly to move into the docking base 4. At this time, the clamping assembly and the inner tilting ring 6 engage in a transmission engagement. A clamping and positioning ring 7 is fixedly installed on the top inner wall of the docking base 4. As the clamping assembly moves, the clamping assembly clamps and positions the clamping and positioning ring 7, thereby achieving a fixed connection between the docking base 4 and the carrying tray 5.

[0040] The clamping assembly specifically includes an assembly fixing ring 8 fixedly installed on the top of the support tray 5, located inside the docking base 4. Multiple ball-head connecting rods 9 are slidably connected at equal intervals along the inner side wall of the assembly fixing ring 8. One end of each ball-head connecting rod 9 has a ball head that engages with the inclined surface and straight surface of the inner wall of the inner inclined ring 6. The other end of each ball-head connecting rod 9 is fixedly mounted with a clamping fixing plate 10, which clamps against a clamping positioning ring 7. When the docking base 4 is assembled onto the support tray 5, the ball head on the ball-head connecting rod 9 contacts the inclined surface inside the inner inclined ring 6. As the docking base 4 continues to be pressed down, the inclined surface pushes the ball-head connecting rod 9 to move, which in turn moves the clamping fixing plate 10. When the ball head reaches contact with the straight surface of the inner inclined ring 6, the clamping fixing plate 10 and the clamping positioning ring 7 are clamped together, achieving the installation and positioning of the docking base 4.

[0041] A tension spring 11 is fitted onto the ball joint connecting rod 9 and located inside the assembly fixing ring 8. Both ends of the tension spring 11 are fixedly connected to the inner walls of the ball joint connecting rod 9 and the assembly fixing ring 8 via hooks located at both ends. When the ball joint connecting rod 9 moves to clamp and position the assembly fixing ring 8 using the clamping fixing plate 10, the tension spring 11 is stretched and under stress. When the docking base 4 and the bearing tray 5 need to be disassembled, the ball joint connecting rod 9 is no longer limited by the inner inclined ring 6, and the tension spring 11, under stress, pulls the ball joint connecting rod 9 in the opposite direction, releasing the clamping and positioning of the assembly fixing ring 8.

[0042] A conical clamping chuck 14, located within a clamping positioning ring 7, is fixedly installed on the top inner wall of the docking base 4. A rotating transmission rod 12 is rotatably connected through the bearing tray 5. A docking protective cover 13 is fixedly installed at the top of the rotating transmission rod 12, and the conical clamping chuck 14 is located inside the docking protective cover 13. Support positioning rings 131 are fixedly installed on both sides of the docking protective cover 13. Inclined locking plates 15 are slidably connected to the top of the support positioning rings 131, and both inclined locking plates 15 are in contact with the top of the conical clamping chuck 14. An arc-shaped elastic support plate 16 is fixedly installed on one inner wall of the support positioning ring 131. The top of one side of the arc-shaped elastic support plate 16 extends above the support positioning ring 131 and is fixedly connected to one side of the inclined locking plate 15. An auxiliary elastic support plate 17 is fixedly installed inside the arc-shaped elastic support plate 16. When installing the docking base 4 and the support tray 5, the docking base 4 is pressed down, causing the conical clamping chuck 14 to insert into the docking protective cover 13. At this time, the bottom slope of the conical clamping chuck 14 contacts the slopes of the two inclined locking plates 15. As the conical clamping chuck 14 continues to move downward, the two inclined locking plates 15 move away from each other, and the arc-shaped elastic support plate 16 and the auxiliary elastic support plate 17 bend and are under stress. When the conical clamping chuck 14 is completely moved into the docking protective cover 13, the two inclined locking plates 15 are located above the conical clamping chuck 14. The arc-shaped elastic support plate 16 and the auxiliary elastic support plate 17, which are under stress, push the inclined locking plates 15 to return to their original position, moving the inclined locking plates 15 above the conical clamping chuck 14 to form a clamping effect, improving the stability of the connection between the docking base 4 and the support tray 5.

[0043] Two exit guide grooves 141 are symmetrically formed on the conical clamping chuck 14. A torsion spring 18 is sleeved on the rotary transmission rod 12, located below the carrying tray 5. The top and bottom ends of the torsion spring 18 are fixedly connected to the bottom of the carrying tray 5 and the torsion spring 18 by hooks set at the top and bottom ends of the torsion spring 18, respectively. When it is necessary to disassemble the docking base 4, rotating the rotary transmission rod 12 causes the docking protective cover 13 to rotate 90°, so that the exit guide grooves 141 on the conical clamping chuck 14 are aligned with the corresponding inclined locking plate 15. At this time, the inclined locking plate 15 releases its clamping limit on the conical clamping chuck 14, and the installation connection between the docking base 4 and the carrying tray 5 is released.

[0044] Two fixed support frames 19 are symmetrically fixedly installed at the bottom of the bearing tray 5. The bearing tray 5 is pre-installed on the ultra-high pressure equipment using the two fixed support frames 19, so that the anvil body 1 can be stably supported and installed when the docking base 4 and the bearing tray 5 are installed.

[0045] Working principle: In use, the bearing pallet 5 is first connected to the external ultra-high voltage equipment through two symmetrical fixed support frames 19 at the bottom, so that the bearing pallet 5 is pre-installed on the ultra-high voltage equipment to provide stable support for subsequent installation. Then, the docking base 4 is assembled on the bearing pallet 5. During this process, the inner inclined surface of the inner inclined ring 6 in the docking base 4 contacts the ball head at one end of the ball head connecting rod 9, pushing the ball head connecting rod 9 to slide on the inner wall of the side of the assembly fixing ring 8, driving the clamping fixing plate 10 at the other end to move. After the ball head moves to direct contact with the inner inclined ring 6, the clamping fixing plate 10 clamps with the clamping positioning ring 7. At the same time, the movement of the ball head connecting rod 9 causes the tension spring 11 sleeved on it and located in the assembly fixing ring 8 to be stretched and stressed. At the same time, the conical clamping chuck 14 at the top of the docking base 4 is inserted into the docking protective cover 13 at the top of the rotating transmission rod 12 on the bearing pallet 5. The bottom inclined surface of the conical clamping chuck 14 contacts the inclined surface of the two inclined locking plates 15. When it moves downward, the two inclined surfaces lock. With the clamping plates 15 moving away from each other, the arc-shaped elastic support plate 16 and its auxiliary elastic support plate 17 on one side of the inner wall of the supporting positioning ring 131 bend under stress. After the conical clamping chuck 14 moves into the docking protective cover 13, the two inclined locking plates 15 are positioned above the conical clamping chuck 14. The arc-shaped elastic support plate 16 and the auxiliary elastic support plate 17 push the inclined locking plates 15 to reverse and reset, locking them above the conical clamping chuck 14, thus achieving clamping and improving the connection stability between the docking base 4 and the bearing tray 5. When it is necessary to disassemble the docking base 4, rotate the rotating transmission rod 12 to drive the docking protective cover 13 to rotate 90°, so that the exit guide groove 141 on the conical clamping chuck 14 corresponds to the position of the corresponding inclined locking plate 15. The inclined locking plate 15 releases the clamping limit on the conical clamping chuck 14, and at the same time, the ball head connecting rod 9 is no longer supported by the inner inclined ring 6. The tension spring 11 pulls the ball head connecting rod 9 to move in the opposite direction, releasing the clamping and fixing plate 10 from clamping and positioning the assembly fixing ring 8, and the disassembly can be completed.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
