Description
Technical field
The utility model belongs to the advanced manufacturing technology field, relates to a kind of selective laser sintering single face dust feeder, relates in particular to a kind of employing and returns the selective laser sintering single face dust feeder that the powder groove is realized.
Background technology
Selective laser sintering (Selective Laser Sintering is called for short SLS) is a kind of rapid shaping that is widely used (Rapid Prototyping is called for short RP) technology, and it is a raw material with the solid powder material, directly cad model is converted into entity.In theory, any powder of hot adhesion that is subjected to all has the raw-material possibility of the SLS of being used as, as macromolecule, pottery, metal dust and various composite powder material.In SLS technology, the powder feeding and spreading technology directly affects the SLS processing quality, and powder feeding and spreading device directly influences device structure, size and reliability etc.
In SLS technology, adopt usually and go up powder feeding and two kinds of automatic powder feeding systems of following powder feeding.On two-sided/following powder feeding is the most traditional existing SLS automatic powder feeding system, two-sided dust feeder has generally been installed a cover respectively and has been comprised a powder feeding cylinder in the workbench both sides, excessive powder cylinder and motor, piston or control valve, supporting device such as fixture is done at interior dust feeder, this two-sided dust feeder technology maturation, easy to operate, can effectively finish SLS powder feeding and spreading technical process, satisfy SLS layering sintered powder demand, but its pair powder feeding cylinder and the powder cylinder structure that overflows make that the overall dimensions of SLS forming machine is bigger, the machine complexity is higher, has machine manufacturing cost height, defectives such as poor reliability.
U.S. Pat 20050263933, US20050263934 have reported dust feeder on a kind of single face respectively, in these two patents, a dress powder platform has been installed as the powder conveying arrangement in the powder-laying roller top, quantitative upward dust feeder can be spread backhaul the required materials of powder and be discharged on the dress powder platform, when powder-laying roller removes journey shop powder backhaul is transported to the opposite side of workbench with powder, fixed blade powder-laying roller through the out-of-date powder that will adorn on the powder platform unload to workbench for spreading the powder use.This device only needs one and goes up the powder feeding cylinder, has reduced the SLS machine dimensions to a certain extent; But in this automatic powder feeding system, last powder feeding cylinder needs respectively powder quantitatively to be unloaded at twice to workbench and dress powder platform, and process is numerous and diverse; And the workbench both sides still need be installed an excessive powder cylinder respectively, have still occupied bigger machine space; Easily friction is impaired to unload powder blade and dress powder platform, the powder-laying roller operation and unload in the powder process powder be very easy to unrestrained, influence shop opaque amount, and working environment polluted.
Summary of the invention
The purpose of this utility model is to overcome the defective of existing SLS dust feeder, a kind of simple in structure, easy to operate selective laser sintering single face dust feeder is provided, when guaranteeing to satisfy SLS round trip powder feeding and spreading demand, reduces the SLS equipment size, reduce the equipment complexity, reduce equipment cost, improve equipment dependability.
The selective laser sintering single face dust feeder that the powder groove is realized is returned in a kind of employing that the utility model provides, and comprises powder-laying roller, powder feeding cylinder, excessive powder cylinder and returns the powder groove.The quantity of the wherein said powder feeding cylinder and the powder cylinder that overflows has only one, is positioned at a side of workbench; Return the quantity of powder groove and also have only one, be positioned at workbench opposite side.Wherein said time the powder groove comprises a cylinder body, a movable floor and the Control Shaft that is connected with movable floor.
In the single face dust feeder that the utility model provides, wherein said movable floor can be positioned at go back to upper and the next two positions of powder groove, and its activity can be controlled by motor or mechanical linkage or other modes by coupled Control Shaft.
The selective laser sintering single face dust feeder that the powder groove is realized is returned in a kind of employing that the utility model provides, its course of work is: the powder feeding cylinder that is positioned at workbench one side provides a certain amount of powder to workbench one side, powder-laying roller begins journey shop powder from workbench one side, and the movable floor that this moment, Control Shaft was controlled back the powder groove is positioned at the next; When powder-laying roller is finished journey shop powder and pass through back the powder groove, unnecessary powder is unloaded to returning in the powder groove, the while powder-laying roller continues to move to back outside the powder groove; When powder-laying roller starts backhaul shop powder, Control Shaft is controlled back powder groove movable floor and is risen to upper, the movable floor and the table plane of returning the powder groove are positioned at a horizontal level, last time reclaimed powder as backhaul shop powder materials, powder-laying roller is finished backhaul shop powder and unnecessary powder is unloaded to excessive powder cylinder, so far finishes a powder feeding and spreading cycle.In the above-mentioned course of work, the powder feeding cylinder once provides the amount of powder can spread the powder materials for twice at least.The above-mentioned course of work of the present utility model can be adjusted according to factors such as dusty material character, technological requirements, as increasing the operation of several times powder pressing in the powder feeding cycle at a shop powder, adjust movable floor according to technical process demands such as shop powder, compactings and be positioned at the next time etc., these all are that those skilled in the art are attainable according to the utility model, and the technical scheme that reaches the utility model purpose according to the disclosed content of the utility model all belongs to scope of the present utility model.The powder feeding cylinder that the utility model relates to and confession powder mechanism, powder-laying roller and shop powder mechanism, time powder trough floor controlling mechanism etc. all adopt prior art.
A kind of employing provided by the utility model is returned the selective laser sintering single face dust feeder of powder groove realization both applicable to last dust feeder, also goes for down dust feeder; Time powder groove of the band movable floor that size of this device employing is little, simple in structure has replaced the double action of a side powder feeding cylinder and excessive powder cylinder, realized single face dust feeder round trip powder feeding and spreading function, reduce the cleaning and the powder recovery operation of two excessive powder cylinders in the existing equipment simultaneously, improved the utilization rate of material to a certain extent; This device has been saved the device space, reduced SLS equipment overall dimensions, reduced the equipment complexity, effectively reduce equipment cost, the reliability of equipment is necessarily promoted, and has further satisfied the SLS technological requirement.
