Summary of the invention
The purpose of the utility model is to overcome the defective that existing SLS goes up dust feeder; Dust feeder on a kind of selective laser sintering simple in structure is provided; Can make things convenient for the purpose of the quantitative powder feeding of realization of intelligence, and the work powder is carried out even preheating, effectively guarantee processing quality.
Dust feeder on a kind of selective laser sintering that the utility model provides; Comprise work top, powder-laying roller, dust feeder; Dust feeder is fixed on the powder-laying roller top, it is characterized in that: dust feeder comprises confession powder chamber, powder fetching groove plate, gets the foundation cream plate, crosses powder passage, preheating device, wherein supplies powder chamber kerve and powder fetching groove plate to join; The powder fetching groove plate is positioned to be got on the foundation cream plate; Get the foundation cream plate and have a powder hole excessively, cross the powder passage and extend to work top from crossing the powder hole, preheating device is positioned at powder fetching groove plate top.
In the last dust feeder that the utility model provides, wherein said powder fetching groove plate is a groove shapes.
In the last dust feeder that the utility model provides, wherein said preheating device is fixed on and supplies perhaps to be fixed on through support and to get on the foundation cream plate on the powder cavity outer wall.
The powder fetching groove plate of the utility model is a movable part, can be by stepper motor or driven by servomotor, do translational motion getting on the foundation cream plate, and accomplish and get a series of function actions such as powder, heating, powder feeding.
Dust feeder on a kind of selective laser sintering that the utility model provides, its course of work is: before beginning to get powder, supply powder chamber kerve and powder fetching groove plate to join, dusty material is in the cavity that supplies powder chamber and the formation of powder fetching groove plate closing; When beginning to get powder, the powder fetching groove plate makes to supply powder chamber kerve to be positioned at the groove top to work top outside translation, and powder flows in the groove because of the gravity effect; After getting powder and accomplishing, the powder fetching groove plate moves to and supplies powder chamber kerve to join to the workbench inboard, and makes and get the powder groove and arrive preheating position, and preheating device is heated to suitable temperature with the powder in the groove; Preheating completion and powder-laying roller arrive when getting the powder position, and the powder fetching groove plate continues to the inboard translation of workbench, and dock in the powder hole of crossing on making groove and getting the foundation cream plate, dusty material from the powder aperture cross the powder passage and fall into work top; After supplying powder to accomplish, get the powder plate and move to the position before beginning to get powder to the workbench outside, accomplish a powder feeding cycle this moment.
According to design demand, in the SLS machine of dust feeder, we can adopt single roller or the auxilliary powder device of two rollers simultaneously, also can once get the unidirectional or two-way powder laying of powder on adopting that the utility model provides; On can installing in SLS equipment that one or two the utility model provides dust feeder with realize single face or two-sided on powder feeding; In the last dust feeder that the utility model provides, can hold in the powder fetching groove plate groove and accomplish the required powder of one or many shop powder, we can control the powder amount of getting through the displacement size of control powder fetching groove plate.These are that those skilled in the art can realize according to the utility model, combination prior art.
The last dust feeder that the utility model provides; Can quantitatively get the purpose of powder through the simple translation motion realization of powder fetching groove plate; And can satisfy the multiple powder requirement of getting, and having increased the free selectivity of functions of the equipments design, simple, the convenient intelligence of apparatus structure, good reliability, applicability are wide; Preheating device is a self-contained unit, is convenient to monitoring and control; Get and only hold the little work powder in the powder groove, powder is tiled in the groove with the formation of thin layer, can evenly be heated to suitable temperature, has guaranteed processing quality.
