Description
Technical field
The utility model belongs to metal powder selective laser sintering increases material manufacturing technology field, and in particular to a kind of selection
The laser sintered powdering scraper device of property.
Background technique
In 3D printing technique industry, (Selective Laser Melting, SLM) technical office is melted in selective laser
It is the following metal parts Laser Direct Deposition technology with development potential in high-end.LM technology is to utilize high-energy
Laser beam fusing is layered on the thin layer powder on powder bed in advance, successively melts stack shaping.In SLM forming process, every layer of laser
After the end of scan, powder feeding cylinder rises certain altitude, and powder is uniformly laid on forming cylinder surfaces by powdering scraper.However, using
When existing powdering scraper device carries out powdering, have the following problems：Due to powder and printing design of part etc., forming zero
Part surface may generate nodularization, warpage contour point, and therefore, powdering scraper may be damaged printing during being laid with powder
Part, or directly blocked at high point, it is difficult to go on smoothly so as to cause powdering process, also reduces printing success rate.
Summary of the invention
In view of the defects existing in the prior art, the utility model a kind of selective laser sintering powdering scraper device is provided can
Effectively solve above-mentioned technical problem.The technical solution adopted in the utility model is：A kind of selective laser sintering powdering scraper dress
It sets, including tool apron, knife rest, pressing plate and scraper, the tool apron is cylindrical structure of the root with square base, and intermediate slide passes through the
One screw lock ring unclamps the first screw on the cylinder of tool apron, and knife rest can be rotated around the cylinder of tool apron, and pressing plate passes through the second screw
It is fixed on knife rest and scraper is pressed on knife rest.
Further, the knife rest is " kitchen knife " shape, and knife handle is internally provided with through-hole, opens along its length immediately below knife handle
There is breakthrough form elongated slot and knife handle lower part is divided into two valves, wherein being provided with threaded hole on a valve and its underpart is connected with blade, separately
It is provided with screw mounting hole on one valve and two valves can be fastened across the hole and are adjacent to by screw；The blade lower part setting pressing plate is pacified
Dress face, pressing plate mounting surface lower part are provided with scraper mounting groove.
Further, the scraper is strip and its cross section is X-shaped, and the material of scraper is elastic material, is scraped
The cutting edge of knife is parallel with the cylinder axis on tool apron.
Selective laser sintering powdering scraper device provided by the utility model has the following advantages that：(1) scraper is elasticity
Body can occur flexible deformation when scraper touches raised points and generates upward component and can cross in print procedure and occur
Lesser raised high point, reduce bring risk and the possibility of failure in print procedure to greatest extent, guarantee powdering process
It goes on smoothly, can also effectively improve printing success rate；(2) knife rest is rotatable, when blade wears, can pass through swivelling tool-holder pair
Abrasion loss compensates；(3) scraper section is " X " type, and cutting edge has four, when a cutting edge abrasion is excessive, can rotate position
Replacement cutting edge is set, scraper use cost is reduced.
Detailed description of the invention

Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.
It should be appreciated that specific embodiment described herein is not used to limit this reality only to explain the utility model
With novel.
As shown in Figure 1, a kind of selective laser sintering powdering scraper device of the utility model, including tool apron 1, knife rest 2, pressure
Plate 4 and scraper 6, the tool apron 1 are cylindrical structure of the root with square base, and intermediate slide 2 is by 3 lock ring of the first screw in knife
On the cylinder of seat 1, the first screw 3 is unclamped, knife rest 2 can be rotated around the cylinder of tool apron 1, and pressing plate 4 is fixed on knife by the second screw 5
It is pressed on knife rest 2 on frame 2 and by scraper 6, the scraper 6 is strip and its cross section is X-shaped, and the material of scraper 6 is
The cutting edge of elastic material, scraper 6 is parallel with the cylinder axis on tool apron 1.
As shown in Fig. 2, the knife rest 2 is " kitchen knife " shape, knife handle 2-1 is internally provided with through-hole 2-2, the underface knife handle 2-1
Be provided with breakthrough form elongated slot 2-3 along its length and the lower part knife handle 2-1 be divided into two valves, wherein be provided on a valve threaded hole and its
Lower part is connected with blade 2-4, and screw mounting hole is provided on another valve and two valves can be fastened across the hole and are adjacent to by screw；Institute
The lower part blade 2-4 setting pressing plate mounting surface 2-5 is stated, the lower part pressing plate mounting surface 2-5 is provided with scraper mounting groove 2-6.
Scraper is elastomer, and when powdering, elastic change can occur when scraper touches raised points and generates upward component
The lesser raised high point that shape and capable of crossing occurs in print procedure, reduces bring risk in print procedure to greatest extent
And the possibility of failure, guarantee that powdering process is gone on smoothly, further increases printing success rate.
When scraper 6 is worn, the first screw 3 is unclamped, swivelling tool-holder changes the distance that scraper 6 arrives powdering plane, to abrasion
Amount compensates.
6 section of scraper is " X " type, and cutting edge has four, can be with 6 position of revolving scraper more when a cutting edge abrasion is excessive
Renew cutting edge, to reduce by 6 use cost of scraper.
