Description

Technical Field

[0001] The utility model relates to the technical field of six-sided top presses, in particular to a top hammer combination structure and a six-sided top press. Background Art

[0002] The ultra-high temperature and high pressure synthesis mold of the six-sided top press is composed of six top hammers and their steel rings with three-dimensional axes perpendicular to each other. The existing top hammer has a small beveled edge downward along its top surface. The function of the small beveled edge is to form a wedge-shaped sealing edge between two adjacent top hammers when the six top hammers squeeze the synthesis block, which is used to seal the energy in the synthesis cavity. On the other hand, since the existing six top hammers are exactly the same in shape, when the bevels of the top hammers touch each other, the top hammers are stuck to each other, and the hammer surface of the top hammer cannot continue to move forward. The compression effect of the top hammer on the synthesis block is limited, affecting the synthesis efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In Example 1, referring to Figure 1-7 A top hammer combination structure comprises a first top hammer 1 and a second top hammer 2, wherein the first top hammer 1 and the second top hammer 2 are both provided with a quadrangular pyramid-shaped hammer top, the hammer top of the first top hammer 1 is provided with a first inclined surface 11, a second inclined surface 12 and a first hammer face 13, the hammer top of the second top hammer 2 is provided with a third inclined surface 21 and a second hammer face 22, the first inclined surface 11 is a contact surface between the first top hammers 1, the second inclined surface 12 is fitted with the third inclined surface 21, the number of the first top hammers 1 is four, the first top hammers 1 are distributed circumferentially, the degree of the angle between the second inclined surface 12 and the first hammer face 13 is smaller than the degree of the angle between the first inclined surface 11 and the first hammer face 13, as shown in FIG. Figure 4-6 In the figure, the degree of angle a is greater than that of angle b, angle b and angle c are complementary angles to each other, the degree of the angle between the second bevel 12 and the first hammer face 13 is less than 45°, the number of second top hammers 2 is two, and the first bevel 11 and the second bevel 12 on the first top hammer 1 are alternately arranged.

[0024] The first hammer face 13 is rectangular, the second hammer face 22 is square, and the area of ​​the first hammer face 13 is smaller than that of the second hammer face 22. Compared with the traditional six-sided top press, when the top hammer is fully pressed, the vertical distance between the second hammer faces 22 is smaller. In terms of equipment size, it can meet the deep extrusion of the synthetic block.

[0025] Reference Figure 8 , a six-sided top press adopts the above-mentioned top hammer combination structure.

[0026] It includes a first hinge beam 3 and a second hinge beam 5, the first hinge beam 3 cooperates with the first top hammer 1, the second hinge beam 5 cooperates with the second top hammer 2, the diameter of the piston cavity of the first hinge beam 3 is smaller than the diameter of the piston cavity of the second hinge beam 5, and also includes a first piston assembly 4 and a second piston assembly 6, wherein the first piston assembly 4 is adapted to the first hinge beam 3, the second piston assembly 6 is adapted to the second hinge beam 5, the diameter of the piston cavity of the second hinge beam 5 is larger, suitable for installing a large-sized piston assembly, and providing greater pressure.

[0027] In this embodiment, the top hammer combination structure and the six-sided top press proposed by the utility model cooperate with each other through four identical first top hammers 1 to form an annular structure, which limits the radial direction of the synthetic block, and uses the second top hammer 2 with a pressure greater than that of the first top hammer 1 to extrude the synthetic block axially, thereby increasing the axial compression size of the synthetic block and effectively improving the synthesis efficiency.

[0028] When the angle between the second bevel 12 and the first hammer face 13 is smaller than the angle between the first bevel 11 and the first hammer face 13, the angle between the third bevel 21 and the second hammer face 22 becomes larger in order to fit with the second bevel 12. Since the area of ​​the second hammer face 22 remains unchanged, when the dimensions of other parts of the second top hammer 2 are not changed, the initial distance between the second hammer face 22 and the piston cavity becomes larger. When the piston runs the same distance, the depth of the second hammer face 22 squeezing the synthetic block is deeper.

[0029] In Example 2, referring to Fig. 9 As shown, the top hammer combination structure includes a third top hammer 7, and four groups of first inclined surfaces 11 are arranged on the hammer top of the third top hammer 7. The number of the second top hammer 2 is one, the third top hammer 7 is arranged opposite to the second top hammer 2, and three groups of first inclined surfaces 11 are arranged on the first top hammer 1.

[0030] Compared with Example 1, in Example 2, the second hinge beam 5 cooperates with the second top hammer 2, and in order to maintain the force balance of the second top hammer 2, the third top hammer 7 opposite to the second top hammer 2 should also adopt the second hinge beam 5, and the second top hammer 2 adopts the first hinge beam 3.

[0031] It should be noted that, in the process of extruding the synthetic block, in order to provide overflow space for the synthetic block, a small slope can be set at the front end of the first top hammer 1 and / or the second top hammer 2 if necessary, but the first slope 11, the second slope 12 and the third slope 21 are still the main pressure-bearing surfaces.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
