Powder drying temperature required for being at.
Collection powder groove 26 is additionally provided on the worktable panel, the outside of the location hole is arranged in the collection powder groove,
The bottom of the collection powder groove is equipped with multiple powder leakage holes 27.After laser cladding forming, collection powder is not drawn by negative pressure powder-suction structure
Powder in funnel can be used hairbrush and be swept into collection powder groove, then enter collection by collecting the powder leakage hole of powder channel bottom
In powder funnel, the recovery utilization rate of powder is improved.
The stainless steel cloth 18 is made using 310S high temperature resistant stainless steel, steel wire used in the stainless steel cloth
Diameter is 1-5mm.The stainless steel cloth is square eye net, and width of mesh is 5mm × 5mm~30mm × 30mm, and powder is dry
Temperature in storehouse is unsuitable excessively high, usually between 100-200 degrees Celsius, can be conducive to dried powder and is avoided that again because of temperature mistake
It is high and powder is caused to aoxidize.It is that stainless steel cloth is in hot environment for a long time in order to prevent using high temperature resistant stainless steel
The powder that oxidation generates iron rust and pollutes recycling occurs prevents powder from falling in stainless in addition, the diameter of stainless steel wire should not be excessively thick
The recycling of powder is influenced on steel wire.
By matrix it is usually Interal fixation on worktable panel when use, laser cladding forming is then carried out on matrix
Or 3D printing forming, it is not trickled down on matrix or worktable panel by the alloy powder that laser melts in print procedure, directly
Powder Recovery process can be entered by location hole by connecing the metal powder fallen on worktable panel, and fall in the powder on matrix
By hairbrush by the positioning hole on powder brush to worktable panel after the completion of 3D printing, alloy powder is in negative pressure powder-suction structure
Under the action of enter in powder dryness storehouse and be dried, it is dry after powder fall directly into screening mechanism and sieved,
Powder, which is fallen directly into, after screening completes complete Powder Recovery work in Powder Recovery storehouse.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
