Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 2.Notice, the structure of this specification institute accompanying drawings depicted, ratio, size etc., all only in order to coordinate the disclosed content of description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the adjustment of the modification of any structure, the change of proportionate relationship or size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still drop in the scope that the disclosed technology contents of this utility model can be contained.Simultaneously, in this specification cited as " on ", D score, "left", "right", " centre " and " one " etc. term, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
As shown in Figure 1, this utility model provides a kind of metal dust conveyer device for selective laser melting unit, comprising: hold the funnel 1 of metal dust, and it is placed in the extruding machine structure in the export department 11 of funnel 1, extruding machine structure includes drive motor and for transporting the roller 2 of metal dust, drive motor is connected with rotating shaft 3 transmission of described roller 2, and the axis perpendicular of the axis of described rotating shaft 3 and described export department 11, tract in export department is cut off by roller 2 up and down, and is uniformly distributed the groove 21 that multiple axis direction along rotating shaft 3 extends in roller circumference.This utility model adopts the roller being circumferentially with groove as extruding machine structure, it can guarantee the velocity of rotation of roller by drive motor and may determine that the conveying capacity of metal dust by arranging the size of groove, so under determining that metal dust is stably carried, moreover it is possible to improve the effective rate of utilization of metal dust.
As the specific embodiment in hopper outlet portion of the present utility model, hopper outlet portion of the present utility model can only one of which duct chamber, so only set an extruding machine structure.In the export department of above-mentioned funnel 1, tract can also be divided into two vertical powder conveyance path side by side, and it is provided with an extruding machine structure in each powder conveyance path, so more accurately control the conveying capacity of metal dust, if need big conveying capacity that two extruding machine structures can be made to work simultaneously, if little one the extruding machine structure of optional unlatching of demand.
Metal dust amount for guaranteeing every time conveying is identical, and the groove inner volume of above-mentioned fluted 21 is identical.
For guaranteeing that tract in export department is cut off by roller up and down, it is to avoid metal dust falls between roller and export department's inwall, the external diameter of above-mentioned rollers 2, more than the internal diameter of export department 11, has the inside groove of accommodating part roller on the inwall of export department 11.
As in figure 2 it is shown, it has two powder conveyance path and state diagram when two extruding machine structures all work for funnel of the present utility model.When metal dust is fallen by funnel, rotating shaft 3 is driven by drive motor and rotates, and drives roller 2 to rotate, and metal dust enters roller and rotates to the groove of top, and is transported in the lower space of export department with the rotation of roller 2, then leaks down.In roller 2 rotation process, in export department, the metal dust above roller is isolated by roller, only enters the metal dust in roller groove and can be rotated into lower section with roller 2.
Roller 2 and rotating shaft 3 in this utility model coordinate transmission by the convex outer surfaces mechanism of the endoporus groove on roller inner holes and rotating shaft 3, and rotating shaft 3 coordinates with brearing bore, the shaft hole matching on the tube wall in bearing top circle face and hopper outlet portion.Having minim gap between roller 2 and hopper outlet portion inwall, export department is cut off by up and down, and when roller 2 does not rotate, the metal dust on export department top will not drain to export department bottom.
This utility model also provides for a kind of selective laser melting unit, metal dust conveyer device in the melting unit of described selective laser adopts the metal dust conveyer device for selective laser melting unit as above, other structures such as moulding cylinder, power spreading device etc. are existing structure, are not described in detail here.
In sum, this utility model is used for metal dust conveyer device and the selective laser melting unit of selective laser melting unit, it adopts the roller being circumferentially with groove as extruding machine structure, it can guarantee the velocity of rotation of roller by drive motor and may determine that the conveying capacity of metal dust by arranging the size of groove, so under determining that metal dust is stably carried, moreover it is possible to improve the effective rate of utilization of metal dust.So, this utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for restriction this utility model.Above-described embodiment all under spirit of the present utility model and category, can be modified or change by any those skilled in the art.Therefore, art has all equivalence modification or changes that usually intellectual completes under the spirit disclosed without departing from this utility model with technological thought such as, must be contained by claim of the present utility model.
