[0038] Specifically, in the implementation of the present application, the atmosphere protection device includes a shell 1, the interior of the shell 1 can form an installation space for the anvil press 2, and it is also a space for creating a reducing atmosphere environment for the anvil press 2; the type of the anvil press 2 can be a diamond anvil press, and there is no specific limitation.

[0039] In order to ensure the smooth functioning of the anvil press 2, a plurality of external connection holes 11 are formed on the top of the shell 1, and each of the external connection holes 11 can be provided with external device connectors with different functions, wherein the external device connectors at least include: an electrical introduction connector 16 and an air film air circuit connector 17, and the electrical introduction connector 16 is used to connect the heating ring of the anvil press 2 to the external temperature control system, so as to meet the temperature requirements of the anvil press 2 during the experiment; in addition, the air film air circuit connector 17 is used to communicate with the air source, thereby transmitting pressure to the anvil press 2.

At the same time, the base plate 14, the main shell 12, and the cover plate 13 are connected by bolts, and the seal 3 can enhance the tightness of the connection between the three.

[0045] In a preferred embodiment, a water cooling assembly is provided inside the housing 1 for supporting the anvil press 2;

[0046] The water cooling assembly is provided to ensure that the anvil press 2 will not be damaged or corroded due to excessively high temperature. The water cooling assembly can control the temperature of the anvil press 2 to a certain extent.

[0051] The window assembly includes: a window glass piece 6, and the window glass piece 6 is arranged in the second mounting hole 15 through a window gasket 7; wherein the material of the window glass piece 6 is sapphire; the second mounting hole 15 is not a direct through hole, but a structure with a certain limiting bottom plate (similar to a stepped structure), so the window gasket 7 and the window glass piece 6 can be set in the second mounting hole 15.

[0052] In order to fix the window glass 6, a window pressure plate 8 is arranged on the side of the window glass 6 away from the inside of the shell 1. The window pressure plate 8 is connected to the shell 1 through a connecting piece to fix the window glass 6. The connecting piece can be a conventional bolt structure.

[0053] In a preferred embodiment, if Figure 3 As shown, an anvil press air film 9 and an air film fixing plate 10 are sequentially arranged on both sides of the anvil press 2; the anvil press air film 9 is used to transmit pressure to the anvil press 2, and an air inlet pipe 21 is arranged on the top of the anvil press air film 9 (see Figure 3 ), can be extended to the external hole 11 to connect with the gas source.

[0054] The air film sheet fixing plate 10 is located on a side of the anvil press air film sheet 9 away from the anvil press 2 and is connected to the anvil press 2 via a fixing member.

[0055] Anvil presses are commonly used for pressure processing in various industrial applications, such as metal forming, powder pressing, composite material processing, etc. Its working principle is mainly to align two or more dies (anvil and punch) through mechanical force and apply pressure between them to complete the material processing.

[0056] When the anvil press is working, the anvil press air diaphragm 9 will be subjected to pressure from the upper die (punch) and transmit an equal and opposite force to balance the pressure of the punch and ensure that the material is evenly stressed; the anvil press air diaphragm 9 can be fixed on the anvil press 2 by the air diaphragm fixing plate 10.

[0057] In a preferred embodiment, a third mounting hole 18 is further opened on the side wall of the shell 1, and the third mounting hole 18 is used for the atmosphere adjustment part. An air port 19 is formed at one end of the atmosphere adjustment part away from the shell 1, and the air port 19 is used to connect with an external vacuum system, thereby forming the vacuum atmosphere environment required by the anvil press 2 to ensure the smooth progress of the test.

[0059] The external system is a reducing atmosphere charging system, and the gas port 19 is also used to be connected to the reducing atmosphere charging system, thereby forming a low-oxygen atmosphere environment required by the anvil press 2 .

[0060] Among them, see Figure 1 It can be seen that the atmosphere adjustment part is an exhaust component 20 arranged at the third mounting hole 18, and the air path in the exhaust component 20 is connected to the inside of the shell 1 through the third mounting hole 18. In this way, no matter whether it is connected to an external vacuum system or a reducing atmosphere inflation system, there is no need to frequently disassemble at the third mounting hole 18. It is only necessary to select different connecting devices at the air port of the exhaust component 20, which can avoid affecting the sealing of the shell 1.

[0061] Based on the above description, the embodiment of the present application proposes an atmosphere protection device for an anvil press, and its specific working principle is as follows:

[0062] First, the anvil press 2 is set in the water-cooled sleeve 4 and fixed, and then the external device connector is connected to the corresponding external device, such as the temperature control system, air source and circulating water system; in addition, the vacuum system or the reducing atmosphere inflation system needs to be connected to the air port 19. After all the pre-test preparations are completed, the corresponding system can be started for testing.

[0063] Specifically, by opening the gas source, the anvil press can be provided with pressure to apply to the sample material through the anvil press air diaphragm 9. Under high temperature and high pressure test conditions, the temperature control system provides the required temperature. At the same time, the vacuum system or the reducing atmosphere inflation system ensures the vacuum or low oxygen of the test environment through the gas port 19 to prevent the sample material from being contaminated.

[0064] It should be noted that the atmosphere protection device of the anvil press is equipped with a highly integrated control device (for example, a central control machine, etc.), so when each system is turned on or off, it can be controlled by technicians at the central control machine according to the test requirements.

[0065] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
