Technical field
The present invention relates to a kind of 3D printing equipment, category 3D printing field, more particularly to one kind have double
The 3D printing equipment of structure.
Background technology
Selective laser melting (Selective Laser Melting, SLM) is that a kind of 3D of metalwork straight forming is beaten
Print technology, it is the later development of rapid shaping technique.Most basic thought of the technology based on rapid shaping, i.e. successively cladding
" increment " manufacture, there is the part of geometry in particular according to three-dimensional CAD model direct forming, metal in forming process
Powder is completely melt, produces metallurgical binding, complicated shape/knot that the technology can not manufacture especially suitable for traditional machining means
The category part of structure.SLM technologies have advantages below：
1) terminal metal part product can directly be manufactured.The existing 3D models of client are handled by proper data and material selects
After selecting, you can directly produce the part that can be used and test, can greatly shorten product development cycle (after general surface does not have to
Handling process, require that high surfaces can reserve appropriate surplus and carry out machining and postorder surface treatment)；
2) it can obtain that there is nonequilibrium state supersaturated solid solution and uniformly the entity of tiny metallographic structure, consistency almost can
Reach 100%, part machinery performance is suitable with forging technology gained；
3) using the laser with high power density, metal is processed with the laser beam of hot spot very little so that process
Metal parts there is very high dimensional accuracy (reaching 0.1mm) and good surface roughness (20~40 μm of Ra)；
4) due to laser spot diameter very little, therefore the laser energy density of metal bath is very high so that uses single component
Metal dust be possibly realized to manufacture part, and alternative metal dust species is also expanded significantly；
5) it is adapted to the workpiece of various complicated shapes, being especially suitable for inside has complicated abnormal shape structure (such as cavity, three dimensional network
Lattice), the complex part that can not be manufactured with conventional method；
Using SLM technologies 3D printing equipment part printing after the completion of, clear up working chamber in not by laser sintered
Excessive powder, because the powder for needing to clear up is more, it is necessary to while forming board be risen, while clearing up unnecessary powder.This is just
A problem is brought, if the height Z of formation of parts is more than the clear space height dimension H in working chamber, because formation of parts
Baseplane can not rise to more than working chamber's upper surface of base plate, then can not clear up the residual powder completed in shape room, and part
It can not take out.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided a kind of 3D printing equipment with duplexing bit architecture, solves
Cleaning inconvenience in conventional 3D printing equipment working chamber, Forming Workpiece size is long and the technical barrier that can not take out.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
3D printing equipment with duplexing bit architecture, including working chamber, working chamber upper end are provided with laser module, it is described into
Shape room lower end is removably connected with formation cylinder, and formation cylinder moving parts, working chamber's exterior lateral sides are provided with formation cylinder
Pickup storehouse is additionally provided with, pickup storehouse upper end is provided with pickup silo roof lid, and pickup storehouse lower end is additionally provided with formation cylinder installing port,
The formation cylinder is movable to pickup storehouse lower end and is connected with formation cylinder installing port.
Further, it is additionally provided with pickup cage in the pickup storehouse, pickup cage can vertical lifting and can be from pickup silo roof lid
Place is stretched out.
Further, it is provided with positioning protection ring in the middle part of the pickup cage.
Further, the pickup cage upper end is additionally provided with suspension ring.
Further, also it is communicated with vacuum cleaner pipe in the pickup storehouse.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is easy to loading and unloading, can be very easily by height gauge
Very little larger Forming Workpiece is taken out, and saves the substantial amounts of pickup time, and extremely safe during taking-up, will not part of damage
And printing device, it is also extremely convenient when clearing up working chamber, improve the cleaning effect of working chamber.
