It is described in detail the technical solution of the application below with reference to the accompanying drawings and in conjunction with the embodiments.
Referring to FIG. 1, a kind of metal powder of the present invention sieves powder device, including sieve powder apparatus main body 1 annular in shape, powder is sieved
Apparatus main body 1 is plastic material, has lower cost and higher applicability, is had when screening metal powder preferable wear-resisting
Property and safety.It sieves powder apparatus main body 1 and is equipped with several sieve pores 2, specifically, sieve pore 2 is evenly distributed on sieve powder apparatus main body 1
And through the ring wall of sieve powder apparatus main body 1, make to be connected in the ring for sieving powder apparatus main body 1 with ring outside, metal powder can be by sieve pore 2
It passes through.If sieve 1 bottom of powder apparatus main body is additionally provided with equally distributed dry screen slot 3, the metal powder positioned at sieve 1 bottom of powder apparatus main body
End can be entered by sieve slot 3 or be left above-mentioned sieve powder device.In different embodiments, sieve pore 2 can have different numbers from sieve slot 3
Amount, shape, such as round and rectangle.
In order to obtain preferable structural strength, sieve pore 2 assumes diamond in shape in one of the embodiments, and sieve slot 3 is triangular in shape.
The sieve pore 2 and sieve slot 3 of above-mentioned shape, which possess sieve powder apparatus main body 1 after offering hole, slot, preferable structural strength, prevents
There is accidental damage later in movement and collision, influence to sieve powder effect.It should be noted that being not limited to equilateral triangle or diamond shape, adopt
It is equally applicable for the scheme that the embodiment illustrates with appropriate deformed aperture or fluting shape.
Since metal powder sieve powder device generates collision with outside at work, by horizontal extrusion stress, in order into
One step ensures structural stability, and the Minimum Internal Angle of diamond mesh 2 is not more than 60 °, such as 60 °, 50 ° in one of the embodiments,
Or 40 ° etc..The lesser interior angle of diamond mesh 2 is located at the top and bottom of sieve pore 2, and left and right ends interior angle is then not less than 120 °.
Any sieve slot 3 has identical spacing away from two neighboring sieve pore 2 in one of the embodiments, that is, sieves slot 3 and sieve
Hole 2 is spaced apart one by one on sieve powder apparatus main body 1.In some embodiments, sieve pore 2 is higher than sieve slot 3 and is located at sieve powder device
The middle position of 1 ring wall of main body.
In one of the embodiments, when sieved metal powder granulates degree is greater than 500 μm, sieve powder device needs stronger
Wear-resistant strength, then sieving powder apparatus main body 1 is nylon, and sieve pore 2, which has 4 to 8, to be advisable.In order to obtain biggish intensity, increase makes
With the service life, sieve pore 2 has 6 in one of the embodiments,.
In one of the embodiments, when sieved metal powder granulates degree is less than 500 μm, sieve powder device does not need relatively strong
Wear-resistant strength, in order to reduce cost, sieve powder apparatus main body 1 is ABS plastic (acrylonitrile-butadiene-styrene (ABS) plastics), sieve pore
2 have 10 to 14.In order to make metal powder that there is good mobility in sieving, sieve in one of the embodiments,
Hole 2 has 12.
In various embodiments, the size of sieve pore 2 is needed according to different production, such as the granularity of metal powder
It is determined with the size of sieve powder device.Usual lesser metal powder granulates degree and sieve powder device, then sieve pore 2 is corresponding smaller；Compared with
Big metal powder granulates degree and sieve powder device, then sieve pore 2 is corresponding larger.Excessive sieve pore 2 is unfavorable for stable structure, accordingly
2 quantity of sieve pore then suitably reduces, and confirmation metal powder sieves the structural strength of powder device after impact several times test.
Referring to FIG. 2, a kind of sieving machine is also disclosed in invention, powder device is sieved including above-mentioned metal powder, wherein further include
The motor 30 that sieve 20 and driving sieve 20 in sieving machine main body 10, sieving machine main body 10 shake.Vibration can be used in motor 30
Dynamic motor or centrifugation motor, metal powder are entered by sieving machine top entry, are gone out after screening into the sieve 20 for crossing vibration by powder
Mouth discharge.Since 3D printing metal powder granulates are superfine, it is easy at 20 center of sieve i.e. by sieving machine top entry powder down
Place forms aggregation.In order to improve traditional sieving machine, screening effect is promoted, 4 to 6 metal powder sieve powder devices are arranged on sieve
On net 20, metal powder sieves the irregular free movement on sieve 20 of powder device under the vibration of sieve 20, thus by metal powder
Last heap is broken up, it is made to be evenly distributed, and then promotes screening effect and efficiency.
Referring to FIG. 1, the contact jaw for sieving 1 bottom of powder apparatus main body and sieve 20 in one of the embodiments, is equipped with
Angle, chamfering reduce the contact surface of sieve powder apparatus main body 1 and sieve 20, and then sieve powder device to sieve after reducing prolonged exercise
The frictional dissipation of net 20 increases the service life of sieve 20.
Metal powder in the manufacture present invention sieves powder device, using the increasing material manufacturing for being adapted to quickly produce, such as using modeling
Expect the mode of 3D printing.Device does not need any support or fixed structure, and fast, economical is easily promoted.
In conclusion structure is simple, by skilful the beneficial effects of the present invention are: metal powder sieve powder device is novel in design
Wonderful setting sieve pore and sieve slot are uniformly distributed the metal powder on sieve under the movement impact of sieve powder device, prevent powder product
Poly- to cause sieve powder low efficiency, effect difference and sieve blocking, metal powder sieving machine guarantees that 3D is beaten in high load capacity printing in turn
Print machine has the ability that continues working, and improves printing effect and reduces failure rate.
It is enlightenment with the above-mentioned desirable embodiment according to the application, through the above description, relevant staff is complete
Full various changes and amendments can be carried out in the range of without departing from this item application technical idea.The technology of this item application
