Description
Technical field
This utility model relates to increasing material manufacturing technology field, is specifically related to a kind of Pu Fen mechanism for SLS and FMS.
Background technology
3D printing technique is the emerging technology that manufacture field is developing rapidly, is the main way of realization of " increasing material manufacture ".The theory " increasing material manufacture " is different from traditional " removal type " and manufactures.Traditional numeric-control manufacture is usually on the basis of raw material, uses the ways such as cutting, grinding, burn into melt, removes redundance, obtain parts, then become final products with Combination of Methods such as assembly, welding.And " increasing material manufacture " is different, it is not necessary to proembryo and mould, just can be generated the object of any shape by the method increasing material, simplify the fabrication schedule of product, shorten the lead time of product directly according to computer graphics data, improve efficiency and reduce cost.
SLS(Selected Laser Sintering) i.e. selective laser sintering rapid forming system, it is first STS file by CAD 3D model conversation, cuts into slices according to certain thickness, obtain the cross section profile of section.Then control laser beam the powder of model solid section is scanned, make powder particles fuse and adhered to one another, progressively obtain the profile of this layer.After completing one layer of scanning, workbench declines a layer cross section height, then carries out paving powder and the sintering of next layer, ultimately forms threedimensional model.
Precoated sand covers molding sand or the core sand of one layer of hard resin film at sand grain surface before referring to moulding, there are cold process and two kinds of coating techniques of full-boiled process: resin is dissolved by cold process ethanol, and during mulling, add hexamethylenamine, and make the two be coated on sand grain surface, ethanol volatilizees to obtain precoated sand；Full-boiled process is preheating to uniform temperature sand, adds resin and makes it dissolve, and stirring makes resin-coating at sand grain surface, adds hexamethylenamine aqueous solution and lubricant, cools down, crushes, sieves to obtain precoated sand.FMS is to use precoated sand as raw materials for production, cuts into slices file according to computer, controls laser beam and be scanned the precoated sand of model solid section, makes precoated sand fusing and adhered to one another, progressively obtains the profile of this layer.After completing one layer of scanning, workbench declines a layer cross section height, then carries out paving powder and the sintering of next layer, ultimately forms threedimensional model.
As it is shown in figure 1, a kind of Pu Fen mechanism in prior art, a moulding cylinder 1 of employing and one are for powder cylinder 2, running roller 3 controls powder and sends into moulding cylinder 1 from for powder cylinder 2, has sent a powder, and running roller 3 returns the top for powder cylinder 2 and waits next layer of paving powder, but the forming parts time is longer, inefficiency.As in figure 2 it is shown, the moulding cylinder 4 used and two auxiliary cylinders 5, but the amount of powder of the needs in auxiliary cylinder 5 is more, easily causes the waste of powder.
Summary of the invention
For solving above-mentioned technical problem, we have proposed a kind of Pu Fen mechanism for SLS and FMS, it not only saves the supply of powder in Liao Pu powder mechanism, the most less part making molding time.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of Pu Fen mechanism for SLS and FMS, it include moulding cylinder, be located at above described moulding cylinder for pave powder running roller, control the first driving means that the workbench upper-lower position of described moulding cylinder moves, be located at described moulding cylinder side and for contain powder for powder cylinder and control described the second driving means moved for the workbench upper-lower position of powder cylinder, also including the auxiliary cylinder being located at described moulding cylinder opposite side for containing powder, the volume of described auxiliary cylinder is less than the described volume for powder cylinder.
Preferably, it is additionally provided with in described auxiliary cylinder and controls the 3rd driving means that the workbench upper-lower position of described auxiliary cylinder moves.
Pass through technique scheme, this utility model uses one to be arranged on moulding cylinder both sides for powder cylinder and an auxiliary cylinder, during paving powder, the powder amount that supplies for powder cylinder provides moulding cylinder at least to lay the powder required for two thickness, and unnecessary powder is temporarily stored in auxiliary cylinder, when carrying out next layer of paving powder and preparing, powder temporary in auxiliary cylinder is sent in moulding cylinder by running roller, complete the paving powder of next layer, the most effectively save part Production Time, and improve the utilization rate of powder, decrease the waste of powder.
