Description
Technical field
This utility model belongs to diamond glomerocryst manufacturing technology, especially relates to a kind of for producing diamond
The mould of glomerocryst.
Background technology
The impact resistance of diamond glomerocryst is better than single-crystal diamond, because it has a high-wearing feature, and impact, and plastic
The superiority of profile and be widely used in oil, on the drill and petroleum extraction tools such as geology and coal, the face of cylinder especially for instrument is resistance to
Mill material.Its shape is usually: disk, cylinder, triangle, cube and cuboid (being limited to draw ratio less than 2.5).
Diamond glomerocryst is usually and uses cubic apparatus hinge type hydraulic press to produce, and this equipment is produced
Major part glomerocryst has a common feature: the draw ratio of glomerocryst is less than 2.5.Along with geology, oil bit manufacturing process not
Disconnected progressive, the draw ratio of required glomerocryst is more than 2.5.Cubic apparatus is being used for the draw ratio diamond glomerocryst more than 2.5
In hinge type hydraulic press production process, the pyrophyllite block as transmission medium is a cube, and six faces are subject to bigger normal pressure,
The key-like glomerocryst stress difference peak that major and minor axis differs greatly is i.e. the middle part of major axis.The sizable glomerocryst of ratio all ruptures from this
Broken, become waste product, yield rate is the lowest.
Utility model content
The purpose of this utility model is to provide a kind of mould for producing diamond glomerocryst, and it has structure letter
Single and be greatly improved the feature of yield rate of diamond glomerocryst, deposit to solve prior art produces diamond glomerocryst
The problems referred to above.
For reaching this purpose, this utility model by the following technical solutions:
A kind of mould for producing diamond glomerocryst, it includes the pyrophyllite block as transmission medium, described leaf
Offer storage tank on cured stone, in described storage tank, be provided with graphite jig, described graphite jig offers some and gathers
Brilliant forming tank, is equipped with diamond mixed powder in described glomerocryst forming tank, wherein, described glomerocryst forming tank uses two ends for circle
The strip groove of arc structure, during molding, the length direction of described glomerocryst forming tank and the main stress direction of graphite jig have folder
Angle A, the span of described included angle A is 25 °～65 °.
Especially, described some glomerocryst forming tank are that parallel interval is distributed on described graphite jig.
Especially, described some glomerocryst forming tank are perpendicular to horizontal direction and are distributed on described graphite jig.
Especially, described some glomerocryst forming tank tilt distribution, on described graphite jig, have folder with horizontal direction
Angle A.
Especially, described storage tank is circular trough, and described graphite jig generally coordinates the circle that described storage tank is arranged
Structure, time die-filling, described graphite jig is positioned in described storage tank rotationally.
The beneficial effects of the utility model are, compared with prior art the described mould for producing diamond glomerocryst
There is following advantage:
1) the glomerocryst forming tank to the glomerocryst that draw ratio is more than 2.5 is optimized design, uses the strip of two terminal circle arc
Shape, also known as " key-like " glomerocryst.This glomerocryst shape decreases corner angle, decreases the waste product that stress causes corner angle defect to bring
Rate；
2), during molding, the length direction of described glomerocryst forming tank and the main stress direction of graphite jig have included angle A.Utilize
Mechanics principle, after carrying out ordered arrangement to mould so that product pressure dissipation suffered by building-up process is uniform, it is to avoid because of pressure
Power is excessively concentrated and is caused product fracture or performance heterogeneity.
Accompanying drawing explanation
Fig. 1 is the structure of the mould for producing diamond glomerocryst that this utility model detailed description of the invention 1 provides
Schematic diagram.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Referring to shown in Fig. 1, Fig. 1 is the poly-for producing diamond of this utility model detailed description of the invention 1 offer
The structural representation of brilliant mould.
In the present embodiment, a kind of mould for producing diamond glomerocryst includes being arranged at cubic apparatus hinge type hydraulic pressure
As the pyrophyllite block 2 of transmission medium on machine 1, described pyrophyllite block 2 offers the storage tank of circle, sets in described storage tank
Being equipped with the graphite jig 3 of circle, time die-filling, described graphite jig 3 can turn an angle in described storage tank.Described graphite
Offering some the glomerocryst forming tank 4 arranged in parallel interval on mould 3, described some glomerocryst forming tank 4 are each perpendicular to
Horizontal direction is arranged, and is equipped with diamond mixed powder in described glomerocryst forming tank 4, and described glomerocryst forming tank 4 uses two ends
For the strip groove of arc structure, during molding, the length direction of described glomerocryst forming tank 4 and the main stress direction of graphite jig 3
There is included angle A, in the present embodiment, described included angle A=45 °, use the design of this form to make the stress of glomerocryst long axis direction reduce,
The pressure dissipation making product suffered in building-up process is uniform, it is to avoid excessively concentrates because of pressure and causes product fracture or performance
Heterogeneity.
Diamond mixed powder uses 230/270 with fine diamond powder metal dust such as titanium (Ti) in addition, nickel (Ni),
Its granularity is-300#, and/or non-metal powder such as silicon (Si), and boron (B) its powder size is-400#, mixes by a certain percentage,
Again the powder mixed is loaded in the graphite jig 3 of prefabricated given shape.And turn an angle, make described glomerocryst forming tank
The length direction of 4 has included angle A with the main stress direction of graphite jig 3, installs the graphite jig 3 of powder through application of vacuum
After, place into (pressure transmission and insulation medium) in pyrophyllite block 2, then on cubic apparatus hinge type hydraulic press 1, carry out high temperature
High-pressure synthesis.
In the present embodiment, the granularity of bortz powder is divided into the granularity no less than 5 groups by thickness.Make small of diamond
Grain obtains the diamond bulk density of maximum in piling up extrusion process.So that the intensity of glomerocryst obtains in terms of internal structure
Improve.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not by above-mentioned example
Limiting, on the premise of without departing from this utility model spirit and scope, this utility model also has various change and change, and these become
