Description

Raw material forming equipment for micro-powder high-pressure preparation microcrystal

Technical Field

The utility model relates to the technical field of artificial diamond, in particular to a raw material forming device for preparing microcrystals by using micro powder high pressure.

Background

Diamond, known as the "king of material", possesses the highest hardness, wear resistance and thermal conductivity, and is widely used in precision machine tools. Such as: diamond, a superhard cutter of cubic boron nitride, a superhard grinding wheel of cubic boron nitride, diamond polishing sand paper, an abrasive belt, diamond grinding paste and polishing liquid and a diamond electroplating grinding head.

The diamond monocrystal raw material is a key material for preparing various diamond tools, and because the diamond particle sizes of various diamond tools are different, the particle sizes of the diamond raw material synthesized at high temperature and high pressure are relatively concentrated (generally between 150 and 550 um), part of the diamond monocrystal raw material needs to be crushed into different particle sizes to adapt to different products, wherein about 50 percent of high-strength diamond raw material is directly used for preparing diamond tool bits, diamond saw blades and the like, and 50 percent of diamond raw material is crushed into diamond powder with different particle sizes to be used for preparing different tools, and diamond monocrystal with the grain size of 54 to 100 um is called as a crushed material and diamond monocrystal with the grain size of less than 54um is called as diamond micropowder.

The "crushed material" obtained by crushing the diamond raw material and the diamond micropowder each account for about 50%. The diamond micro powder is obtained by grinding original diamond raw materials through air current, 15% -25% of diamond micro powder with grain size smaller than 2um is generated in the diamond crystal crushing process, and the consumption of the diamond micro powder in the grain size section is low, so that various diamond micro powder manufacturers are backlogged in a large amount. The diamond microcrystal is pressed by the diamond micropowder with the grain size smaller than 2um at high pressure, so that a large amount of backlogged 2um is turned into wealth by the fine diamond micropowder, the obtained diamond microcrystal has higher strength and self-sharpening property, and the diamond micropowder is loose and cannot be directly put into equipment, and is required to be mixed with other materials to be agglomerated in the microcrystal preparation process.

After the micro powder is mixed and agglomerated, the micro powder is manually pressed into a cake shape and then put into a press machine, when the micro powder is pressed into the cake shape, the micro powder is manually extruded, the extrusion efficiency is low, the labor intensity of workers can be increased after long-time work, and the work efficiency is low.

Therefore, it is necessary to provide a molding apparatus for forming a fine powder raw material for high-pressure microcrystals to solve the above-mentioned problems.
