Abstract
The utility model discloses a whitewashed device that falls that metal 3D printer used. The device is including powder level sensor (1), powder storehouse (2), changeover portion (3), fall whitewashed ware (4), servo motor constitutions such as (5). Its theory of operation is that the metal powder is annotated to powder storehouse (2) riga, and what of powder volume can detect through powder level sensor (1), metal powder whereabouts gets into whitewashed ware (4), comes the control powder volume that falls through taking the recess to fall the rotation of powder axle (402). Through come real -time what of in powder storehouse metal powder of mastering at powder storehouse top installation powder level sensor (1), can effectively prevent to add the powder excessive with the emergence that lacks the whitewashed condition. The utility model discloses simple structure, easily realize, have simultaneously save space, reliable and stable characteristics.
Description
Technical field
This utility model patent relates to metal 3D printer apparatus field, particularly to a kind of metal 3D
The powder discharging device that printer uses.
Background technology
At present, with powder as raw material, the 3D being carried out part by constituency sintering/melting process prints skill
Art is the most quickly to manufacture the focus of area research, and wherein typical technology includes: precinct laser sintering,
Precinct laser fusion etc..The technological process of these technology above-mentioned is similar to: first, on processing plane upper berth
One layer of material powder, then processing thermal source carries out district operation according to the cross sectional shape of part to powder,
Mold the cross section profile of part.
3D printing shaping technology is the system engineering technology of a kind of multi-crossed disciplines, with powder as raw material
3D printing technique in, its forming process necessarily includes storage and the supply of powder stock.As work
The basis of skill molding, the storage of powder stock and the seriality of feedway with reliability necessarily to whole
Forming process has very important impact.
3D printing technique mainly exists as a kind of important means manufacturing part, its advantage: take layering
Manufacture method, the complexity of part does not affect molding, can directly manufacture arbitrarily complicated part；Become
Type precision is higher；Metal parts belongs to metallurgical binding, and its performance exceedes traditional casting.
The automatic powder feeding system of 3D printer many employings powder feeding cylinder at present, this automatic powder feeding system paving powder scraper needs
Across two cylinders, one-stroke returns again to original position after terminating, this mode elapsed time long and
Long travel easily causes the abrasion of scraper, causes scraper blade life to shorten, and the abrasion of scraper can cause
The decline of paving opaque amount.And use powder falling mode powder feeding to have shortening scraper stroke, take up room little,
Add powder flexible, facilitate the advantages such as controlled.
Utility model content
This utility model main purpose is to improve the shortcoming of old automatic powder feeding system with not enough, it is provided that a kind of simple,
Stable, reliable dust feeder.
The powder discharging device that a kind of metal 3D printer uses, it is characterised in that including: pass equipped with powder amount
The powder cabin 2 of sensor 1, changeover portion 3, powder falling device 4 and servomotor 5；Powder cabin 2 is with changeover portion 3 even
Connecing, powder falling device 4 is arranged on below changeover portion 3；Powder falling device 4 includes outside powder falling device shell and powder falling device
Powder falling axle in shell；Powder falling axle is cylinder, and cylinder has for filling the recessed of powder along generatrix direction
Groove, servomotor 5 drives powder falling axle 402 to rotate.Servomotor 5 drives powder falling axle 402 to rotate and makes
Metal dust falls.
Described powder cabin equipped with powder quantity sensor 1, can detect the number of powder amount in powder cabin.Further,
Changeover portion 3 upper end cross-sectional width is 40mm-100mm, and lower end cross-sectional width is 5mm-15mm, converges
Poly-angle is 25 °-80 °.Recess width is 3mm-6mm, deep 2mm-3mm.Described powder falling device
Shell 401 and powder falling axle 402 have the gap of 0.2mm-1mm.Powder falling axle uniformly has along generatrix direction
4 for filling the groove of powder.
Further, powder falling axle 402 groove both sides all have sealing ring to seal, and prevent metal dust from overflowing.
Further, powder falling axle 402 two axial ends all has seal washer to seal, and effectively prevents dust
Foreign bodies etc. enter.
Further, the number for powder amount is each according to load volume and the powder falling axle 402 of single groove
The angle that powder falling turns over determines.
This utility model compared with prior art, has the advantage that
1. this utility model is by using powder falling axle with groove to realize quantitatively supplying powder, reduces the wave of powder
Take.
2. sealing structure is good, the generation of the situations such as effective anti-leak-stopping powder, powder spilling.
3. compact conformation occupies little space.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, but enforcement of the present utility model
Mode is not limited to this.
First pass through powder input port 201 in powder cabin 2, fill the metal powder of 300-500 mesh.
As it is shown in figure 1, be loaded with metal powder in powder cabin 2, the probe of powder quantity sensor 1 gos deep into powder cabin 2
Bottom, can detect powder amount number, can avoid adding the excessive powder waste caused of powder amount and powder
Amount deficiency causes lacking powder.
Metal dust in powder cabin 2 is by falling into powder falling device 4 powder falling axle 402 after the convergence of changeover portion 3
In groove, servomotor 5 drive powder falling axle 402 to rotate, make powder from powder falling axle 402 groove
Fall.
Different powder falling amounts can be obtained, as half-twist can obtain single by the difference of the anglec of rotation
The powder amount of groove, rotates 180 ° of powder amounts that then can obtain two grooves, and a powder falling amount is at 50g-200g
Between.
When changing powder, powder cabin upper cover 202 can be unloaded, and powder cabin bucket 203 be cleaned out, so
After add new powder.
Above-mentioned for this utility model preferably embodiment, but embodiment of the present utility model is not limited to
Above-mentioned, other without departing from this utility model essence and principle lower made change, modify, substitute,
Combination, simplification, all should be the substitute mode of equivalence, within being included in protection scope of the present invention.
