Abstract
The invention discloses a kind of Tapered Cup high pressure torsion mould, including upper die and lower die retainer plate and lower mould, the upper mould is monolithic construction；The lower mould is by dividing the valve that mould forms to close structure, and when dividing mould to be bonded completely under two under symmetrical two, the inner chamber of lower mould forms a complete taper die cavity, and the taper die cavity matches completely with upper mould；There is provided lower mould retainer plate outside lower mould；Divide the bottom of mould to be machined with rectangle respectively under two and divide groove；By placing brake block in rectangular channel, the moment of torsion from lower mould is applied to and is placed on the material of taper die cavity.The present invention closes structure by the way that lower mould is arranged into valve, not only can fast take out product, also greatly improves the intensity and the ability to bear of radial load and moment of torsion of lower mould；Fixation, separation and slippage problems that valve closes structure are efficiently solved simultaneously；The high pressure torsion to Tapered Cup is realized, the crystal grain of material is obtained refinement and reaches Ultra-fine Grained and nanocrystalline yardstick.
Description
Technical field
The present invention relates to mould applications, specifically a kind of Tapered Cup high pressure torsion mould.
Background technology
Tapered Cup has substantial amounts of application, such as nozzle, Vehicle nose, high explosive anti-tank cartridge, drill bit etc. in engineering.These parts
All apply under special occasion, physical property, mechanical performance to material etc. have very high requirement, if desired for higher
Intensity, fatigue resistance, corrosion resistance etc..Substantial amounts of research shows, when material grains reach Ultra-fine Grained or nanocrystalline yardstick,
These performances of material will obtain larger raising.Large plastometric set technique processing lumpy Ultra-fine Grained and can be received as one kind in recent years
The technique of the brilliant material of rice has obtained fast development.After large plastometric set, the crystal grain of material is refined, mechanical performance,
Corrosion resistance etc. is obtained for larger raising.High pressure torsion is one kind of large plastometric set technique, by being loaded in tradition
Cheng Zhong, effective moment of torsion is applied to material, so that the crystal grain of material obtains refinement and reaches Ultra-fine Grained and nanocrystalline yardstick.
The content of the invention
It is an object of the invention to provide a kind of Tapered Cup that Tapered Cup performance boost is realized using high pressure torsion technique
High pressure torsion mould.
To achieve the above object, the present invention provides following technical scheme：
A kind of Tapered Cup high pressure torsion mould, including upper die and lower die retainer plate and lower mould, the upper mould are monoblock type knots
Structure, upper mould are made up of cope plate, cylindrical upper padding plate and taper punch-pin；The lower mould under symmetrical two by dividing mould to form
Valve closes structure, and when dividing mould to be bonded completely under two, the inner chamber of lower mould forms complete a taper die cavity and circular mold cavity, and
The taper die cavity matches completely with taper punch-pin, and the diameter of the circular mold cavity is more than the diameter of cylindrical upper padding plate, described
The diameter of cylindrical upper padding plate is more than the diameter of taper die cavity；Lower mould retainer plate is provided with outside lower mould；Divide mould under two
Bottom be machined with rectangle respectively and divide groove, when dividing mould to be bonded completely under two, two rectangles divide groove to be also bonded and formed completely
Rectangular channel；By placing brake block in rectangular channel, the moment of torsion from lower mould is applied to and is placed on the material of taper die cavity.
As the further scheme of the present invention：Under two mould will be divided to be fixed respectively with fixture.
As further scheme of the invention：Two screwed holes are got on lower point of mould, and are entered using soket head cap screw
Row is fixed.
Compared with prior art, the beneficial effects of the invention are as follows：Novel and reasonable structure of the present invention, by the way that lower mould is arranged to
Valve closes structure, not only can fast take out product, also greatly improves the intensity of lower mould and holding for radial load and moment of torsion
By ability；The fixation of structure is closed to valve by setting fixture to realize simultaneously, by setting lower mould retainer plate to prevent valve from closing structure
Separation, by setting rectangular channel (brake block) to prevent valve from closing structure and skidding；And then the high pressure torsion to Tapered Cup is realized, make material
The crystal grain of material obtains refinement and reaches Ultra-fine Grained and nanocrystalline yardstick.

Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1-8, a kind of Tapered Cup high pressure torsion mould, including upper mould 1, lower mould retainer plate 2 and lower mould 3, institute
It is monolithic construction to state mould 1；The lower mould 3 is worked as under two by dividing the valve that mould 31 forms to close structure under symmetrical two
When point mould 31 is bonded completely, the inner chamber of lower mould 3 forms a complete taper die cavity 32, and the taper die cavity 32 and upper mould 1 are complete
Full matching.
Divide mould 31 to fix under two, mould 31 will be divided to be fixed respectively with fixture 4 under two, its fixed form can
With using mounting technology known in the art；Such as：Two screwed holes can be first got on lower point of mould 31, then using interior
Hex screw is fixed.
During radial load is applied, in order to prevent dividing mould 31 to go out due to the effect by radial load under two
Existing segregation phenomenon, is provided with lower mould retainer plate 2 outside lower mould 3；During moment of torsion is applied, in order to prevent upper mould 1 and lower mould 3
There is skidding, divide the bottom of mould 31 to be machined with rectangle respectively under two and divide groove 33, when dividing mould 31 to be bonded completely under two
When, two rectangles divide groove 33 to be also bonded completely and form rectangular channel 34；By placing brake block in rectangular channel 34, effectively will
Moment of torsion from lower mould 3, which is applied to, to be placed on the material of taper die cavity 32, it is achieved thereby that to the high pressure torsion of Tapered Cup, is made
The crystal grain of material obtains refinement and reaches Ultra-fine Grained and nanocrystalline yardstick.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Make a variety of changes.
