The two-port of block extrusion chamber is respectively provided with plug, and described plug passes sequentially through titanium sheet and carbon block is pressed on carbon plate,
Except that described composite sheet package assembly includes three pieces of hard alloys by the setting of upper, middle and lower position
Reference block, is provided with composite sheet compound body between adjacent hard alloy benchmark block, described composite sheet compound body with
Carbon plate is paid for first between adjacent hard alloy benchmark block；Described composite sheet compound body include resistant to elevated temperatures cup and
Bowl cover, is provided with superhard material powder and the hard alloy Synthetic block of uniform laying, described cup in described cup
Superhard material powder is squeezed in bottom of cup by lid and cup lid merga pass hard alloy Synthetic block.
The bottom of described cup all towards the hard alloy benchmark block in centre position, with this by superhard material powder
Material, located at the medium position of carbon pipe, when being easy to High Temperature High Pressure synthesis in cubic hinge press, makes superhard material
Powder is at the central high temperature of temperature province.
Described superhard material powder conventionally adopts cubic boron nitride and binding agent or diamond and binding agent
Component.
Described cup and bowl cover conventionally use metal zirconium or metal niobium or metal tantalum to make molding.
For easy to make, described pyrophyllite block adopts upper and lower two pieces of combinative structure.
Beneficial effects of the present invention：
1st, the rigidity of the synthesis assembly of present invention raising composite sheet flatness is good, in cubic hinge press system
Synthesis composite sheet can reach the flatness that composite bed is less than 0.1mm.
2nd, the present invention pushes up the flatness effect of synthetic system, the compound piece performance of synthesis up to abroad two sides
Good stability, and the composite sheet of good stability is more suitable for processing center of numerical-control machine tool and uses.
