Description
Technical field
The invention belongs to anti-oxidation technical field of mold, more particularly to a kind of anti-oxidation cavity plate of vacuum and its application method,
Moulding press.
Background technology
Powder metallurgy is to produce metal or be used as by the use of metal dust (or mixture of metal dust and non-metal powder) former
Material, through overmolding and sintering, manufacture metal material, compound and all kinds product technology.Magnesium powder, rare earth La,
Spontaneous combustion can occur in an atmosphere for the metal dusts such as Ce, and in order to prevent the oxidation of material, generally use oxidizable material is in vacuum hand
Operated in casing.By oxidizable material powder, (such as externally-applied magnetic field) is compressing under given conditions, in routine
It can not possibly be completed in glove box.The anti-oxidation cavity plate of vacuum avoids oxidizable powder body material during compressing, air
In oxygen powder is aoxidized, vacuum glove box and moulding press are made of one by prior art, and press surrounding will also be done
Into with atmospheric isolation, by the oxidizable material powder prepared be directly placed into glove box link one press die in, keep away
Exempt from powder body material in oxygen, cause the volume of equipment very huge, complicated, interface oxygen everywhere is easily let out
Leakage, complex operation and influences operating efficiency, and glove box is the special accessories of press, and utilization rate is not high, and not only cost increases
Add, and cause unnecessary waste.And can not meet that factory produces in batches on a large scale, it is only suitable for carrying out in the lab
Single sample operation compressing on press.
In summary, the problem of prior art is present be：Complex operation, work effect be present in the existing anti-oxidation cavity plate of vacuum
Rate is low, and utilization rate is not high, and cost is higher, and space-consuming is big.
The content of the invention
The problem of existing for prior art, the invention provides a kind of anti-oxidation cavity plate of vacuum and its application method, into
Swaging machine.
The present invention is achieved in that a kind of anti-oxidation cavity plate of vacuum, and the anti-oxidation cavity plate of vacuum is provided with：
Cavity plate body；
The cavity plate body is bolted link sealed base；
The cavity plate body links vacuum corrugated pipe by KF vacuum adapter.
Further, a cylindrical groove is opened in the inside of the cavity plate body, leads directly to female bottom circular hole, and bottom open 6 it is recessed
Mould bottom thread circular hole.
Further, the cavity plate body links vacuum corrugated pipe by the first KF vacuum adapter.
Further, the sealed base center is provided with first annular groove, and first annular groove places the first O-shaped rubber ring；
6 whorl of base circular holes are provided with the sealed base, the sealed base is bolted on cavity plate body
Bottom.
Further, the KF vacuum adapter of vacuum corrugated pipe lower end the 2nd is transferred with the KF vacuum of cavity plate bodies top the first
Head is linked, and seal washer is inserted in locked clip device, upper end chain seal cap；
Further, the second annular groove is placed with the second O-shaped rubber ring in the closure.
Another object of the present invention is to provide a kind of application method of the anti-oxidation cavity plate of the vacuum, the vacuum oxygen
Change cavity plate application method be：Oxidizable powder body material and punch-pin are loaded into the anti-oxidation mould of vacuum in vacuum glove box；Very
Empty bellows and vacuum corrugated pipe closure installs, and vacuum corrugated pipe is scalable, the both ends of die ontology and atmospheric isolation.
Another object of the present invention is to provide a kind of moulding press using the anti-oxidation cavity plate of the vacuum.
The present invention realize it is compressing during oxidizable powder body material and air isolate so that powder body material is not easy
It is oxidized.Prior art is that profiling operation is carried out in glove box, and glove box needs to be passed through argon gas holding always in operating process
Air pressure balance in case, it is consumed so having a certain amount of argon gas, and this programme mould need not be pressed in glove box always
Type operate, only need to load oxidizable powder body material in glove box, can be completed with common press operation outside, thus with it is existing
Technology compares the usage amount for reducing argon gas 90%, and prior art Magnetic field press price ten is tens of thousands of, and moulding is huge, and this mould
Compact, can independently take out, it is easy to operate, it is only necessary to 1,000 yuan of processing charges, thus saved 95% expense cost,
Save 90% lab space.In summary, the present invention can be independently operated, easy to operate, and cost is cheap, compact.
