Description
Technical field
The invention belongs to powder packaging technical field, more particularly to the packing device of a kind of 3D printing active metal powder.
Background technology
Increasing material manufacturing (AM), also known as 3D printing, by the three-dimensional modeling data of CAD (CAD) by material by
The cumulative manufacture entity component of layer is referred to as causing the intelligent Manufacturing Technology of " the third time industrial revolution ".The original that increasing material manufacturing uses
Material need to have higher sphericity, preferable mobility, the particle diameter distribution more concentrated and lower oxygen content.Thus upper
It states under requirement, for the logical powder directly produced by powder by atomization stove, it is necessary to by stringent processing, could obtain and meet 3D
Print desired grade metal powder.
It is found by being investigated to domestic and international metal powder Packing Condition, powder packaging is simpler and cruder, and a kind of plastics are antivacuum
Packaging, is open type as metal bucket or plastic barrel, and packaging is simple and fast.Another common packaging uses vacuum plastic sealing,
Using the excellent packaging material of barrier property (air-tightness) and stringent sealing technique and requirement, can effectively prevent packaging powder with it is outer
The contact of boundary's impurity not only can avoid powder moisture absorption, the moisture absorption, but also can prevent secondary pollution.
There are two types of existing main packing methods, the first powder packaging is fairly simple quick, using the non-real empty package of plastics,
It is open type as metal bucket or plastic barrel, but titanium is handled when using the method always with atmosphere during powder-processed
When alloy powder, it is easy to cause oxygenation, the moisture absorption of titanium alloy powder.Powder contacts with air easily entrain impurity for a long time,
Powder is caused to pollute.Another common packaging uses vacuum plastic sealing, using the excellent packaging material of barrier property (air-tightness)
And stringent sealing technique and requirement, contact of the packaging powder with introduced contaminants is can effectively prevent, powder moisture absorption had both been can avoid, has inhaled
Tide, and secondary pollution can be prevented, but the drawbacks of such method, is being packed in fixed space, internal pressure is less than an air
Caking phenomenon or gas leakage easily occur for the gaseous state of pressure, long-time storage powder.In summary problem, this patent design
A kind of packing device being exclusively used in active metal powder.
Invention content
The purpose of the present invention is to provide a kind of 3D printing packing device of active metal powder, solve to inflammable easy
It is quick-fried, oxygen content increases when easily being packed by the more demanding active metal powder of oxygen contamination, clarity and powder moisture absorption caking is asked
Topic.
A kind of packing device of 3D printing active metal powder, including aggregate tank 1, batch can holder 2, charging ball valve 3, gloves
Case 4, stainless steel tube 5, air bleeding valve 6, intake valve 7, electromagnetic induction sealer 8 and pail pack 9.Aggregate tank 1 equipped with metal powder
2 handstand are placed on batch can holder, the tank mouth connection charging ball valve 3 of aggregate tank 1, the lower end connection stainless steel tube of charging ball valve 3
5, stainless steel tube 5 is connected to inside glove box 4, and the inlet amount of powder is controlled by feeding ball valve 3, air bleeding valve 6 is housed on glove box 4
With intake valve 7, glove box 4 is vacuumizing and applying argon gas process is exhausted and is inflated by air bleeding valve 6 and intake valve 7；Electromagnetism
Induction sealer 8 is located in glove box 4, and the lower end of stainless steel tube 5 is that pail pack 9 passes through electromagnetism after powder is packed into pail pack 9
Induction sealer 8 seals bucket.
The application method of above-mentioned packing device, specific steps and parameter are as follows：
1, it will stand upside down on batch can holder 2 lifting equipped with the aggregate tank 1 for having sieved the active metal powder finished first, collection
The tank mouth of batch can 1 is connect with charging ball valve 3 and stainless steel tube 5, and 4 outside of glove box is connect with internal environment by stainless steel tube 5,
Aggregate tank 1 is gone out powder and is controlled using charging ball valve 3；
2, glove box 4 is opened, pail pack 9 is put into glove box 4；
3, intake valve 7 is closed, air bleeding valve 6 is opened, whole take out very is carried out to glove box 4 by the vacuum pump of external connection
Sky closes air bleeding valve 6 and vacuum pump stopping vacuumizes when pressure reaches -0.1Mpa；
4, intake valve 7 is opened, argon gas is filled with into glove box 4, when pressure vacuum gauge pointer is 0, is indicated in glove box 4
External pressure dynamic balance, glove box 4 is full of argon gas, rear to close intake valve 7；
5, pail pack 9 is placed in 5 lower section of stainless steel tube of connection aggregate tank 1, open charging ball valve 3 into luggage powder；
6, it after completing dress powder, is sealed with electromagnetic induction sealer 8.
The aggregate tank 1 and the connection of stainless steel tube 5 connect for clamping hoop type, cassette connection or flanged joint；
Pail pack 9 is aluminium pot, stainless cylinder of steel or other materials.
Protective gas described in step 4 is argon gas, nitrogen or other inert gases.
The advantage of the invention is that：
1) packaging process uses inert gas shielding, and the present apparatus needs first to vacuumize to be carried out inert gas and be filled with again, thus
It needs the present apparatus that there is good leakproofness, is related to intake valve and air bleeding valve design；
2) feeding device before encapsulating is closed using charging ball valve realizes that powder is isolated with outside air, avoids hand stock
Powder moisture absorption, oxygenation problem and impurity pollution；
3) this patent is used to handle any granularity section powder, especially 15-53 microns of section can effectively be avoided because of vacuum
State causes powder compacting caking effectively to solve the problems, such as powder oxygenation under the conditions of argon gas protection packaging, in packaging process not with
Contacting external air reduces introduced contaminants and is mixed into, the final quality assurance for realizing 3D printing metal powder and long term storage
Quality stability.
