Embodiment 1

[0014] Embodiment 1, as shown in Figure 1, the ultra-high pressure mold of the six-sided top press machine is composed of four non-heating anvils 1 in the horizontal direction and two heating anvils 2 in the vertical direction, and the hammers of the four non-heating anvils 1 The linear size ratio A:B between the heated surface and the non-heated surface is 1:1.3, and the hammer surface of the non-heated anvil 1 is a ridge-shaped surface that protrudes from both sides of the hammer surface along the heating direction to the center of the hammer surface at δ=4° The angle of the sealing surface matched with the sealing surface of the heated anvil 2 is α=20° and it transitions with the 4° arc of the hammer surface. The angle of the sealing surface between the non-heated anvils 1 still adopts the original six-sided top The sealing angle of the top hammer may be slower than that of the original six-sided top hammer. When the sealing surfaces between the four non-heating top hammers ...

Embodiment 2

[0015] Embodiment 2, as shown in Figure 2, the ultra-high pressure mold of the six-sided top press machine is composed of four non-heating anvils 1 in the horizontal direction and two heating anvils 2 in the vertical direction, and the hammers of the four non-heating anvils 1 The straight-line size ratio A:B of the heated and non-heated surfaces is 1:1.1, the hammer surface of the non-heated anvil 1 is a plane (δ=0°), and the sealing surface angle α matching the sealing surface of the heated anvil 2 is 30°. The angle β of the sealing cone surface of the heating anvil 2 is 30°, which is parallel to the corresponding sealing surface of the non-heating anvil 1. There is also a square cone-shaped sealing gasket 4 between the sealing surfaces of the heated top hammer 2 and the non-heated top hammer 1 of the ultra-high pressure chamber. Since the angle of the sealing surface of the heating anvil 2 is equal to the angle of the sealing surface of the non-heating anvil 1 matched with ...

Embodiment 3

[0016] Embodiment 3, as shown in Figure 3, the ultra-high pressure mold of the six-sided top press machine is composed of four non-heating anvils 1 in the horizontal direction and two heating anvils 2 in the vertical direction, and the hammers of the four non-heating anvils 1 The straight-line dimension ratio A:B of the heated surface and the non-heated surface is 1:0.9, and the hammer surface of the non-heated anvil 1 is a ridge-shaped surface protruding from both sides of the hammer surface along the heating direction to the center of the hammer surface at δ=3° The frustum surface formed by cutting off the top of the ridge, the middle part of the hammer surface is a plane with length = C, and the sealing surface matched with the sealing surface of the heating anvil 2 is an arc surface, and the radius of curvature is R3. The angle β of the sealing surface of the heating anvil 2 is 35°, and there is an arc transition between the large slope and the radius of the arc is R2. R2 ...

Abstract

An ultrahigh-pressure die set for the diamond synthesizing press by pressing in six directions is composed of 4 non-heating pressing hammers, 2 heating pressing hammers and several sealing pads used for the gap between adjacent pressing hammers. The size parameters and relative position parameters of said hammers are also disclosed.

Description

technical field [0001] The invention belongs to the technical field of superhard material production, and in particular relates to an ultra-high pressure mold for a six-sided top press machine for diamond synthesis. Background technique [0002] The production of artificial diamond in my country's superhard material industry mainly adopts the hinged six-sided top diamond press. The ultra-high pressure mold is a multi-axis structure without a cylinder, and is surrounded by six anvils perpendicular to each other on the three-dimensional axis. The two top hammers also have the function of electrification to electrically heat the composite block. The six top hammers have the same shape and size and are made of hard alloy. The lower part of the top hammer is a cone with a large upper part and the lower part is a square Hammer surface, each side of the hammer surface is crowned by a sealing surface, a large inclined surface and a cone, and the width of the four sealing surfaces on e...
