Description
Technical field
This utility model is related to a kind of device of sizing of pressurizeing for superhard material products base substrate isostatic cool pressing.
Background technology
The method of traditional fabrication superhard material products base substrate is：The formula material of superhard material products is processed into mixing equal
Even half-dried wet mash, is colded pressing using punching block on a hydraulic press and is formed, and this product base substrate is due to compressing on a hydraulic press
When, simply one side is pressurized, so the consistency of product base substrate is uneven, blank strength is poor, after causing product blank sintering,
The quality of product is unstable.Therefore, high density to be obtained, high-quality superhard material products, now using isostatic pressed pressurization of colding pressing
The method of molding, needs superhard material products base substrate is placed in a fexible film hermetic bag during its pressurization, then evacuation,
Isostatic pressed pressurization is just carried out finally.Traditional fexible film hermetic bag capability and performance is poor, is easily damaged, and fexible film sealing
If the thickness of bag is too thin or too thick, the effect that can all affect isostatic pressed to pressurize.Therefore, it is necessary to be further improved.
Utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, easy to operate, low cost for superhard material
The device of material products base substrate isostatic cool pressing pressurization sizing, it is secondary by being carried out to superhard material products base substrate with isostatic cool pressing method
Pressurization setting process is processed, and improves its consistency.
By a kind of device of sizing of pressurizeing for superhard material products base substrate isostatic cool pressing of this purpose design, including for
The fexible film hermetic bag of encapsulation superhard material products base substrate, it is characterised in that：The fexible film hermetic bag is at least while open
Mouth is arranged, and its thickness is 5-20 μm；Superhard material products base substrate is the base substrate that Jing hydraulic presses are prefabricated into various geometries；It is superhard
After material product base substrate is positioned over fexible film hermetic bag, evacuation process is carried out by vacuum pump, and seal opening.
The fexible film hermetic bag three-side-sealed openings at one side.
It is provided with the fexible film hermetic bag opening for sealing the enclosuring structure that closing is open.
The vacuum nozzle for evacuation is provided with the fexible film hermetic bag.
This utility model improves the pressurization of superhard material products base substrate isostatic pressed by arranging special fexible film hermetic bag
The effect of molding, effectively improves consistency, and the fexible film hermetic bag is durable in use, low cost of manufacture, more reliable performance.Tool
Body is that superhard material products base substrate is positioned in fexible film hermetic bag, and carries out evacuation process, then carries out isostatic cool pressing
Pressurization sizing, isostatic cool pressing pressure medium is hydraulic oil, and pressure is 100-250Mpa, due to the flexible thin film of product billet surface
Hermetic bag oil removal is protected, so hydraulic oil will not penetrate into product billet surface, but product billet surface can all be subject to incorgruous
Pressurization, so product base substrate this fexible film hermetic bag carries out isostatic cool pressing pressurization sizing, effect more preferably, effectively improves base substrate
Consistency.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to this utility model.
First embodiment
Referring to Fig. 1-Fig. 3, this is used for superhard material products base substrate isostatic cool pressing and pressurizes device of sizing, including for encapsulating
The fexible film hermetic bag 1 of superhard material products base substrate 2, at least openings at one side of the fexible film hermetic bag 1 are arranged, its thickness
For 5-20 μm；Superhard material products base substrate 2 is the cuboid base substrate that Jing hydraulic presses are prefabricated into；Superhard material products base substrate 2 is placed
After fexible film hermetic bag 1, evacuation process is carried out by vacuum pump, and seal opening.
Furtherly, 1 three-side-sealed openings at one side of the fexible film hermetic bag, superhard material products base substrate 2 is from opening
Place is put in fexible film hermetic bag 1.
