Description
Technical field
The utility model relates to a kind of superhard material processing unit (plant), pressure transmission and sealing device under particularly a kind of HTHP.
Background technology
Superhard material comprises diamond, cubic boron nitride and glomerocryst thereof etc., because its excellent physical chemistry is widely used in the industrial circle in modern times.At present, superhard material is produced the monolithic devices pyrophyllite in lumps that required HTHP sealing medium all adopts common pyrophyllite and dolomite to be pressed into.Under HTHP, the sealing property of this pyrophyllite in lumps descends, and causes heating two ends and " blowing out " phenomenon often occurs; Make the synthetic cavity deflection in the pyrophyllite big, technology is unstable, simultaneously; For guaranteeing the sealing effectiveness of pyrophyllite material, the stoving temperature integral body of pyrophyllite in lumps is on the low side, is difficult to make the high pressure transmission performance of dolomite pressure transmission material to be able to performance; Simultaneously, the ratio of the shared composite block of pressure transmission material is still higher.And only the heat-insulating property through the pressure transmission material realizes the influence to the temperature field, and it is limited that it improves effect.In addition, because compacting pyrophyllite mould therefor weight is big, production efficiency is low, and the pressed density of pyrophyllite in lumps is also on the low side, thereby is difficult to satisfy high-performance and the high efficiency requirement that superhard material is synthetic and grow.
Summary of the invention
The utility model technical problem to be solved just is to provide a kind of good seal performance, pressure transmission effective, the compound pyrophyllite assembled block with pre-sealed limit that synthetic cavity temperature field and pressure field are more mated.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
Involute with following assembly by the laterally zygomorphic assembly of going up of structure; Described upward assembly or following assembly include shell and the pressure transmission part that is embedded in enclosure; Described shell is the cuboid that the middle part such as is provided with at axle and installing hole that is connected and through hole; Described pressure transmission part is the revolving body that an end is big, an end is little, and its profile and installing hole are complementary, and the middle part is provided with and the corresponding to hole of outer casing through hole; The described intersection of going up other per two adjacent surfaces except that involutory surface in assembly or the following assembly is provided with rib; Rib is provided with the pre-sealed limit of " V " type, and wherein: the through hole of shell is descending at last, installing hole in the said last assembly, and the pressure transmission part is the revolving body that the upper end is little, the lower end is big; The installing hole of shell is last in the said assembly down, and through hole is following, and the pressure transmission part is the revolving body that the upper end is big, the lower end is little.
Press such scheme, the through hole of said pressure transmission part is clear opening or reducing through hole.
Press such scheme, said shell adopts the pyrophyllite composite.
Press such scheme, said pressure transmission part adopts the dolomite composite.
Press such scheme; Said pressure transmission part material adopts the dolomite composite that adds metal (or nonmetal) conductor powder (or particle), and metal (or nonmetal) conductor powder (or particle) is like the β-Al of iron, aluminium, molybdenum, graphite, tungsten-cobalt carbide carbide alloy, alkali metal containing
2O
3Deng, and realize further insulation and auxiliary effect of generating heat.
Press such scheme, said pressure transmission part is that a cylinder or the end that the frustum of a cone or an end are big, an end is little is provided with cylinder or the half dolioform block that shrinks awl.
The utility model is the pressure transmission part of increase tendency through using vertically wall thickness from outside to inside; The volume ratio of the pyrophyllite of reduced that HTHP dewaters down, phase transformation and volume contraction and thermal conductivity are higher; Increase thing under the HTHP and stablized, do not had the ratio of the more superior pressure transmission part dolomite of the lower pressure transmission of obvious volume contraction, thermal conductivity and heat-insulating property mutually; Improved the pressure in the synthetic chamber and improved the pressure distribution in the synthetic chamber, the different electric resistance structures at the place of diverse location vertically that forms thus simultaneously can form parallelly connected bypass effect by the interior graphite heater of involutory coelosis; Graphite heater middle district temperature is vertically suitably reduced; In conjunction with the good heat-insulating property of pressure transmission part, can promote that temperature more tends to balance in the synthetic cavity, more mate with synthetic chamber pressure inside gradient.Through pre-sealed limit is set, can obviously improve sealing property; Reduce the consumption of pyrophyllite rheology to sealing strip position, increase the ratio that it plays the pressure transmission effect, significantly promote the pressure transmission performance; Can strengthen simultaneously supporting role, the stability of raising equipment and technology to hammer side, top.
The beneficial effect of the utility model: the compound pyrophyllite assembled block with pre-sealed limit that the utility model provides adopts split combination structure, can design independently Technology for Heating Processing to pressure transmission part and shell; Strengthened the sealing property of pyrophyllite composite block; Reduced " blowing out " phenomenon that HTHP occurs down; Reduced the consumption of pyrophyllite rheology to position, pre-sealed limit; Increase the ratio that it plays the pressure transmission effect, improved the pressure transmission performance greatly, reduced the synthetic of superhard material and the required external pressure of growing; Through adopting the dolomite composite that adds metal (or nonmetal) conductor powder (or particle) to make the pressure transmission material, its auxiliary heating and insulation effect are strengthened, improve the uniformity of synthetic cavity temperature field and the matching of temperature field and pressure field.In addition, this pre-sealed limit with the compound pyrophyllite assembled block on pre-sealed limit is strong to top hammer lateral support effect, has increased the service life of top hammer; Mould is simple, and is in light weight, improved the stability of production efficiency, equipment and technology, satisfies superhard material is synthetic and grow high-performance and high efficiency requirement.
