Specific workflow: in conjunction with attached drawing, being illustrated the working principle and workflow of the utility model, device
Workflow mainly includes powder feeding process, powdering process, clout removal process.
Powder feeding process: in all metal powder place of being stored within storage powder case 1-1, system is detected according to powder falling funnel clout
The feedback information of mechanism 2-1-5 in time carries out powder feeding to powder falling funnel 2-1-1.When powder feeding, power spreading device 2 moves to storage powder
The lower section of case 1-1 keeps the powder falling mouth of Chu Fenxiang corresponding with the powder inlet of powder falling loophole, and system controls relevant opening, closure
Mechanism carries out powder feeding.Entire powder feeding process can carry out simultaneously with electron beam calcination bisque, and then save process time.
Powdering process: power spreading device 2 uses roller, scrapes powder formula, the combined type powdering side that mobile powder falling formula three is integrated
Formula.During powdering, powdering module 2 moves on horizontal table 5 along straight line walking module 3, in the process, titanium
Alloy powder successively scrapes powder by funnel 2-1-1 powder falling, pre- powder scraping sheet 2-2-1 respectively in advance, pressure roller 2-3-1 is compacted, flexibility scrapes powder
Pack 2-2-3 scrapes four steps of powder.Using intermediate powder falling two sides press-powder, scrape powder structure design the two-way paving of one-stroke may be implemented
Powder improves powdering efficiency.2-1-2-7 is driven by motor in flour stirring mechanism 2-1-2, screw pair is driven, so that flour stirring is dialled
Fork 2-1-2-1 carries out reciprocal flour stirring campaign, and flour stirring mechanism 2-1-2 can make powder equal to avoid powder tubercle/bridging phenomenon
It is smooth uniformly to guarantee powder falling for even distribution, but also the measurement of the powder surplus in funnel 2-1-1 is more accurate, in order to avoid occur one
The less phenomenon of the more one side powder of side powder influences powdering effect in turn.Clout detection module 2-1-5, that is, correlation photoelectricity is opened
Derailing switch group can be carried out through surplus of the local transparent part 2-1-1-1 on powder falling hopper walls to the metal powder in funnel
Detection illustrates that the powder surplus inside powder falling funnel is insufficient, when three sensors receive signal simultaneously to carry out in time
Automatic powder feeding.Length adjustment mechanism 2-1-3's can be designed so that power spreading device 2 automatically adjusts having for powder falling funnel 2-1-1
Powdering length is imitated, the automatic adjustment of the size and location to powdering region may be implemented in the control in conjunction with system to the powder falling time.
The material of guard shield 2-4 forms Magnetic Shielding Effectiveness using the soft magnetic material of high permeability, while to post radioactive ray thin in outside
Film, side wall post thermal insulation film, play the heat-insulated effect put and be accused of, extend the service life of device.
Powdering principle: Figure 15 is the principle simplified schematic diagram of powdering process, as shown, in the metal powder of powdering module 2
It is stored in powder falling funnel 2-1-1, system carries out real-time control to powder falling and powder supply, and mobile powder falling formula design can be reduced
The inertia mass of power spreading device 2, while reducing influence of the powdering course powder accumulation to drip molding to a certain extent.Powdering mistake
When journey starts, with the movement of power spreading device 2, powder constantly falls from powder falling funnel 2-1-1, and after powder falling, powder is first
Powder is scraped by pre- powder scraping sheet 2-2-1, thicker metal bisque is suspended to suitable thickness, powder is uniformly spread out in advance and is had is pre-
The effect of compacting, while the uncured splatter particle being entrained in powder can be taken away.Subsequent metal pressure roller module 2-3
The metal bisque completed in advance is pressed through further to be compacted, in this step, if there is biggish Local warping and
If cured splatter particle, since having for pressure roller submodule 2-3 is vertically directed mechanism 2-3-5, rigid rolls 2-3-1
Small displacement can be carried out along vertical direction, it is possible to guarantee that rigid rolls 2-3-1 passes through above-mentioned metal bump.
Rigid rolls 2-3-1 jumps over after metal bump, due to the self weight and rubber block 2-3-5-4 thrust of rigid rolls 2-3-1, so that
Pressure roller 2-3-1 can be returned to rapidly and smoothly original horizontal position.Pressed powder process improves the consistency of metal bisque,
There is preferable passability to metal bump simultaneously, improve the reliability and fluency of experiment or processing.It finally carries out soft
Property scrape powder process, the metal bisque by above-mentioned pressed powder process can scrape powder thin slice group 2-2-3 by flexibility.If machined part
Local warping and splatter cured granulate it is smaller, if not generating protrusion relative to powdering plane, last flexibility
The bisque being compacted will not be acted on by scraping powder thin slice group 2-2-3.If in pressed powder process with the presence of metal bump,
Due to metal pressure roller 2-3-1 jump over protrusion when the micro-displacement that generates so that bisque is in the position where metal bump along gold
Belong to pressure roller and axially produces one or more small salient line.After compacting process, flexibility is scraped powder thin slice group 2-2-3 and is being met
When to metal bump line, zigzag flexible metal foil can generate local bending and then smoothly by metal bump, and
Remaining excess metal powder is struck off.By above-mentioned powder falling, in advance scrape powder, press-powder, flexible four steps for scraping powder, it can be achieved that
Uniform ground, high-compactness, high reliability powdering effect.
Excessive powder removal process: during powdering, in order to guarantee the uniform ground and high-compactness of bisque, powder falling amount is wanted
It is suitably above powdering amount, therefore a part of powder clout will be generated on the table.As shown in figure 16, powder falling funnel 2-1-1,
Pre- powder scraping sheet 2-2-1, rigid rolls 2-3-1, the flexible Design of length for scraping powder thin slice group 2-2-3 are all slightly longer than the length of molding room 6
Degree, this makes extra metal powder that can be extruded to rigid rolls 2-3-1 and the flexible two sides for scraping powder thin slice group 2-2-3 with before
Face.The excessive powder of two sides is extruded into the powder falling slot 4-1 of 6 two sides of molding room, and the excessive powder of leading portion will be reversed
Molding room 6 is promoted to serve as powdering powder by another rigid rolls 2-3-1 when powdering.Then, above-mentioned to be mounted on power spreading device 2
On the lower end clout scraping block 2-2-4 deeply scrape inside powder tank 4-1.As the reciprocating motion of power spreading device 2 is so that in powder falling slot 4-1
Clout scraped powder agglomates 2-2-4 and scraped back and forth, when clout passes through above-mentioned powder falling mouth 4-1-1 in powder falling slot 4-1, clout
It is fallen by powder falling mouth 4-1-1, so that all pushing without clout always in work top 5 and powder falling slot 4-1, guarantees that vacuum is indoor
Processing environment cleaning.The clout of whereabouts is slipped over by clout dispatch tube 4-2 to the powder inlet of recovery cylinder 4-3, subsequently enters recycling
The low side of cylinder 4-3 is gathered in the top of sliding block 4-4.When clout is run up to it is a certain amount of when, sliding block lifting unit 4-5 starts to drive at this time
Dynamic, band movable slider 4-4 rises vertically along recovery cylinder 4-3, and the metal residue biscuit that recovery cylinder bottom is entered from powder inlet 4-3-1 is transported
Go out powder 4-3-2 mouthfuls at the top of to recovery cylinder, and then be recovered to clout in storage powder 1-1 case, realizes recycling and follow in time for clout
Ring utilizes.The design is capable of the powdering clout on timely cleaning work platform surface and realizes recycling for clout, saves space, saves
The slightly link of manual cleaning clout, is more suitable for the operating condition of electron beam 3D printing.
