Description
Technical field
The utility model belongs to superhard material synthesis technical field, particularly a kind of new meshing formula diamond synthesis block.
Background technology
Adamantine composition principle is: by diamond synthesis block is pressurizeed, heated, graphite column is completed by graphite to adamantine transformation.Diamond synthesis block is the key factor that affects diamond product quality, and traditional diamond synthesis block is made up of graphite column, conducting steel ring, heating element heater and pyrophyllite block etc.When energising, make heating element heater heating by conducting steel ring, heat, through reaching graphite column with the insulating barrier of heating element heater close contact, makes graphite be converted into diamond under superhigh-temperature and-pressure.
Along with the development that diamond synthesis press maximizes, diamond synthesis block also expands thereupon, and the energy that in synthetic cavity, graphite column needs is just more and more higher.But the package assembly of diamond synthesis block does not but change, and causes in diamond building-up process thereupon, sealing strip easily drops, the poor accident of blowing out that easily causes of sealing effectiveness, " venting big gun " phenomenon increases, and causes economic benefit significantly not promote along with the expansion of synthetic cavity.
Utility model content
The purpose of this utility model be to provide a kind of rational in infrastructure, can effectively stop the new meshing formula diamond synthesis block that " venting big gun " phenomenon occurs.
For achieving the above object, the technical solution of the utility model is: a kind of new meshing formula diamond synthesis block, comprise that graphite column, graphite column outside are provided with insulating bowl and heater element successively, and heater element two ends are provided with conducting steel ring; Between conducting steel ring and heater element two ends, be provided with successively from outside to inside pyrophillite sheet and white clouds flag, conducting steel ring and heater element are arranged with pyrophyllite in lumps outward; Described pyrophyllite block comprises half block and lower half block, upper half block is made up of pyrophillite sub-block mutually fastening from abutting end and upper pyrophillite mother tuber, lower half block is made up of the cured stone piece of the inferior lobe mutually fastening from abutting end and pyrophillite mother tuber, upper pyrophillite sub-block and the cured stone piece of inferior lobe abutting end are concave shaped, and upper pyrophillite mother tuber and lower pyrophillite mother tuber abutting end are interior convex.
Described upper pyrophillite mother tuber and lower pyrophillite mother tuber inwall are respectively equipped with dolomite clinker and lower dolomite clinker, and the clear size of opening that the cured stone piece of upper pyrophillite sub-block, upper dolomite clinker, lower dolomite clinker and inferior lobe forms is consistent.
Between described insulating bowl and graphite column, be provided with air-breathing metal level.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises that graphite column, graphite column outside are provided with insulating bowl and heater element successively, and heater element two ends are provided with conducting steel ring, between conducting steel ring and heater element two ends, be provided with successively from outside to inside pyrophillite sheet and white clouds flag, conducting steel ring and heater element are arranged with pyrophyllite in lumps outward, described pyrophyllite block comprises half block and lower half block, upper half block is made up of pyrophillite sub-block mutually fastening from abutting end and upper pyrophillite mother tuber, lower half block is made up of the cured stone piece of the inferior lobe mutually fastening from abutting end and pyrophillite mother tuber, upper pyrophillite sub-block and the cured stone piece of inferior lobe abutting end are concave shaped, upper pyrophillite mother tuber and lower pyrophillite mother tuber abutting end are interior convex, it is rational in infrastructure, pyrophyllite block is vertebration, can not cause sealing strip to drop, good sealing effect, be conducive to improve the quality of products, can effectively stop gas to be gone out and the generation of the big gun accident of exitting, effectively protection top hammer, reduce and split the generation of hammer accident, reduce production costs.
2, between insulating bowl and graphite column, be provided with air-breathing metal level, in diamond building-up process, air-breathing metal level can absorb the air and the Yin Gaowen that after diamond synthesis block is compressed by press, are sealed in synthetic cavity makes the carbon dioxide of dolomite decomposition generation, thereby avoids the generation of diamond release post-synthesis phase " venting big gun ".
