Abstract
The invention relates to a metallic 3D (three-dimensional) printing atomization device which comprises a graphite melt delivery pipe used for delivering liquid metal, an atomizer used for conically diverging the liquid metal and a heating insulation pipe. The graphite melt delivery pipe is arranged in the heating insulation pipe, connected with a gas pressure device and communicated with the inside of the atomizer. The metallic 3D printing atomization device feeds the liquid metal by gas pressure, one atomizer is omitted, consumption of high-pressure gas is reduced, production cost is lowered greatly, blockage of the atomizer cannot be caused, and quality of obtained products is good.
Description
Technical field
The present invention relates to 3D printing technique field, relate in particular to a kind of metal 3D and print atomising device.
Background technology
3D prints (3D printing), be a kind of of rapid shaping technique, it is a kind ofly to take mathematical model file as basis, uses motlten metal (alloy), powdery metal (alloy) or the plastics etc. can jointing material, carrys out the technology of constructed object by the mode of successively printing.The maximum feature of this technology is that it almost can produce the article of any shape.International and domestic research frontier have been become at present.
3D prints and normally adopts digital technology file printing machine to realize.Past, its field such as mould manufacture, industrial design of being everlasting was used to modeling, existing just gradually for the direct manufacture of some products, had had and had used this technology to print the parts that form.The Computerized three-dimensional of take designs a model as source, discrete and the numerical control molding system by software hierarchy, utilize the modes such as laser beam, hot melt nozzle that the special materials such as metal dust, ceramic powders, plastics, cell tissue are successively piled up and cohere, the moulding that finally superposes, produces entity products.By machining modes such as mould, turnning and millings, to raw material, shape, cut with final production finished product different from traditional manufacture, 3D prints 3D solid is become to several two dimensional surfaces, by material processed successively stack are produced, greatly reduce the complexity of manufacture.This digitlization manufacturing mode does not need complicated technique, does not need huge lathe, does not need numerous manpowers, directly from computer graphics data, just can generate the part of any shape, makes to manufacture to be able to extend to wider production crowd scope.
In 3D printing technique, all need to use atomizer.Existing 3D printer is all generally to adopt secondary atomization, open the liquid outlet of fluid reservoir bottom, metal liquid in fluid reservoir is due to Action of Gravity Field, flow in the first atomizer, high pressure draught in the first atomizer is dispersed metal liquid, it is one-level atomization, metal liquid after one-level atomization enters in the second atomizer, high pressure draught in the second atomizer flows to different from the high pressure draught in the first atomizer, form crosscurrent, metal liquid is dispersed again, i.e. secondary atomization, thus metal liquid is printed gradually on matrix.Such printer need to be used two atomizers, and structure is comparatively complicated, and equipment cost is higher; in two atomizers, all to pass into gases at high pressure, waste widely resource, in addition; metal liquid, because Action of Gravity Field enters in atomizer, often can cause atomizer to stop up, and needs periodic maintenance.
Summary of the invention
The technical problem to be solved in the present invention is: in order to provide a kind of simple in structure, anti-clogging, saving gas usage, lower-cost metal 3D to print atomising device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of metal 3D prints atomising device, comprise graphite smelt spout for delivery of liquid metal, for by the tapered atomizer of dispersing of liquid metal and heating and thermal insulation pipe, described graphite smelt spout is arranged in heating and thermal insulation pipe, graphite smelt spout is connected with pneumatic shuttle, graphite smelt spout and atomizer internal communication.
Consider that 3D printer of the prior art is all generally to adopt secondary atomization, cost is higher, and metal liquid is entered in atomizer and may be caused atomizer to stop up by Action of Gravity Field in addition, very inconvenient.
The present invention only arranges a second level atomizer, original one-level atomization is changed into and adopts pneumatic shuttle that metal liquid is pressed in the atomizer of the second level, saved the cost of an atomizer, and reduced the consumption of gases at high pressure, adopt air pressure to be pressed into the obstruction that metal liquid has also been avoided atomizer, its successful is better than existing 3D and prints atomising device.
In addition, the present invention is also provided with heating and thermal insulation pipe outward in graphite smelt spout, prevents that metal liquid is cooling in graphite smelt spout, thereby stops up graphite smelt spout.
The invention has the beneficial effects as follows: metal 3D of the present invention prints atomising device and adopts air pressure to send into metal liquid, save an atomizer, reduced the consumption of gases at high pressure, greatly reduced production cost, and can not cause atomizer to stop up, the product quality obtaining is better.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation that metal 3D of the present invention prints a preferred embodiment of atomising device;
In figure: 1. graphite smelt spout, 2. heating and thermal insulation pipe, 3. atomizer, 4. high pressure draught, 5. matrix, 6. deposition base substrate.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of metal 3D prints atomising device, comprise graphite smelt spout 1 for delivery of liquid metal, for by the tapered atomizer of dispersing 3 of liquid metal and heating and thermal insulation pipe 2, described graphite smelt spout 1 is arranged in heating and thermal insulation pipe 2, graphite smelt spout 1 is connected with pneumatic shuttle, graphite smelt spout 1 and atomizer 3 internal communication.
The present invention only arranges a second level atomizer 3, original one-level atomization is changed into and adopts pneumatic shuttle that metal liquid is pressed in second level atomizer 3, saved the cost of an atomizer 3, and reduced the consumption of gases at high pressure, adopt air pressure to be pressed into the obstruction that metal liquid has also been avoided atomizer 3, its successful is better than existing 3D and prints atomising device.
Add man-hour, pneumatic shuttle produces gas and constantly the metal liquid in fluid reservoir is pressed in graphite smelt spout 1, heating and thermal insulation pipe 2 is all the time to metal liquid heating and thermal insulation, metal liquid enters atomizer 3 through graphite smelt spout 1, metal liquid is now with certain pressure, and atomizer 3 produces the high pressure draught 4 of taper, with the metal liquid collision with pressure, produce atomizer (atomizing) cone, thereby on matrix 5, evenly print deposition base substrate 6.
Compared with prior art, metal 3D of the present invention prints atomising device and adopts air pressure to send into metal liquid, has saved an atomizer, has reduced the consumption of gases at high pressure, greatly reduces production cost, and can not cause atomizer to stop up, and the product quality obtaining is better.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
