Embodiment Construction

[0013] Example 1 As shown in Figure 1 and Figure 2, two heated anvils 1 and four non-heated anvils 2 are made of hard alloy, with a large slope angle α = 46°, and the hammer surface of heated anvil 1 is square, non-heated The hammer face of heating anvil 2 is rectangular, the angle of sealing surface of heating anvil 1 is η=60°, the angle of small slope is θ=65°, the angle of sealing surface of non-heating anvil 2 and heating anvil 1 is γ=30°, The transition surface angle δ=34.5°, and the sealing surface angle β=40° between adjacent hammer surfaces of the unheated anvil 2 .

[0014] The working method is: six hinged oil cylinders and their corresponding two heating anvils 1 and four non-heating anvils 2, two heating anvils 1 and four non-heating anvils 2 form an ultra-high pressure working chamber, and the synthetic The block 4 is located in the ultra-high-voltage working chamber, and the two heating anvils 1 are also energized to electrically heat the synthesis block 4. Befor...

Abstract

A method for making a six-surface press for preparing artificial diamond to play the role of two-surface one, and its pressing hammer are disclosed. Said method features that unheated 4 pressing hammers are synchronously moving to form a sealed pressing cylinder and the heated two pressing hammers are continuously moving to press the target and synthesize the diamond at ultrahigh temp under ultrahigh pressure. Said pressing hammer has a square front surface and the angle seal surface is 42-66 deg.

Description

technical field [0001] The invention relates to a method for a hinged six-sided top diamond press to realize the work of a two-sided top press, and also relates to an anvil used in the method, belonging to the technical field of superhard materials. Background technique [0002] The ultra-high pressure composite mold of the hinged six-sided top artificial diamond press is composed of six anvils whose three-dimensional axes are perpendicular to each other, two of which are also electrified to electrically heat the composite block. The six faces of the block are pressurized synchronously. During the ultra-high pressure boosting process and the subsequent composite pressure holding and pressure replenishment process, the compression displacement of the six anvils on the composite block is the same, and the material flow of the composite block is formed. Twelve sealing edges and six faces of the anvil form an ultra-high pressure synthesis cavity. See the book "Manufacturing of ...
