Description

Technical Field

[0001] The utility model relates to the technical field of ultrahigh pressure synthesis, in particular to a male anvil for a combined anvil, a female anvil for a combined anvil and a combined anvil. Background Art

[0002] Chinese patent application number 200910172757.8 discloses a tetrahedral press top hammer, including a top hammer body, which is a cylindrical body. Three inclined surfaces are provided at one end of the top hammer body with its center line as the axis. The angles between the three inclined surfaces and the center line of the top hammer body are all 50°-60°. A concave spherical surface is provided on the cross section formed by the three inclined surfaces with the center line of the top hammer body as the axis. The concave spherical surface and the three inclined surfaces intersect to form three edge lines. Three small inclined surfaces are provided on the three inclined surfaces at positions below the three edge lines, with angles of 5°-10° to the inclined surfaces. The four top hammer bodies with concave spherical surfaces are butted together with the center of the concave spherical surface as the center.

[0003] In the above technical solution, a concave spherical surface is used as the working surface, and each concave spherical surface has three lines, which is more conducive to the sealing of the synthesis chamber and meets the requirements of the tetrahedron press for the synthesis chamber, so that the temperature and pressure distribution in the synthesis chamber are more uniform. However, the above technical solution cannot directly support the cultivation of cabochon diamonds. The existing artificial diamond cultivation process simulates the environment when natural diamonds are formed deep in the earth, creating a high-pressure and high-temperature environment for synthetic diamonds, forming octahedra and cubes, and finally processing the synthetic diamonds according to the required shape and color. However, due to the atomic structure of diamond itself, it has relatively hard physical properties, so the finishing cost of cabochon diamonds is relatively high. If cabochon diamonds that meet the standards can be cultivated in the synthesis chamber during the cultivation process, the production cost of cabochon diamonds can be reduced. Utility Model Content
