Summary of the invention
The purpose of this invention is to provide a kind of based on capillary model-free rapid molding device; This device can directly change geometry entity into by the computer numerical geometrical model; Be applicable to materials such as metal, resin; And efficient is high, the scope of application is more extensive, and another object of the present invention provides said forming method based on capillary model-free rapid molding device.
The objective of the invention is to realize: based on capillary model-free rapid molding device through following technical proposal; Comprise a high-temperature crucible, the bottom of high-temperature crucible offers a plurality of micropores, and the micropore below is provided with a pallet moving up and down; When being full of metal liquid in the micropore; Metal liquid in the high-temperature crucible can flow on the pallet through micropore, and when gassy in the micropore or vacuum, metal liquid can not flow on the pallet through micropore under capillary effect.
The top of said high-temperature crucible is provided with one and can moves up and down and be used for to micropore injecting gas or metal liquid or make the mobile converter that becomes vacuum in the micropore.
Forming method based on capillary model-free rapid molding device comprises the following steps:
A, metal liquid is presented in the high-temperature crucible;
B, the break-make of micropore is set; Let metal liquid from micropore, pass through if desired; Then in micropore, inject metal liquid, interrupt passing through of metal liquid in the micropore if desired through mobile converter, then can be through mobile converter injecting gas or make and become vacuum in the micropore in micropore;
C, metal liquid flow on the pallet through micropore; Move down pallet; Metal liquid continues to flow down and constantly is cooled to and is part; Utilize the switch of the surface tension control micropore of metal liquid, control the flow of metal liquid, the translational speed of pallet simultaneously, make cooled part form required shape.
Can find out from above-mentioned characteristic of the present invention, the invention has the advantages that:
(1), compare, the material ranges that this technology is suitable for is extensive, as long as the liquid of the micropore inwall of high-temperature crucible and part material does not take place to soak into, particularly is applicable to the generally metal material of use, and application prospect is more wide with existing rapid prototyping technology;
(2), compare, production efficiency improves greatly, can reach industrial rate request with existing rapid prototyping technology;
(3), compare, can directly obtain part, save numerous casting technique links by the computer numerical model with traditional casting technique;
(4), this technology need only operate the micropore that needs state to change and get final product, generally rapid prototyping technology then need all control the everywhere material;
(5), open space environment has microgravity, high vacuum characteristic; Surface tension will be most important power; The problem of not having metal liquid oxidation or other chemical reaction is again solidified direction and also can in process of setting, be changed more neatly, therefore; Space environment will more can be brought into play this technological advantage, and this technology is expected to play a role in utilization in the outer space structure manufacturing in future and discarded space trash.
Description of drawings
The present invention will explain through embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is an apparatus structure sketch map of the present invention
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation:
Preferred embodiment
As shown in Figure 1 based on capillary model-free rapid molding device; Comprise a high-temperature crucible 1, the bottom of high-temperature crucible 1 offers a plurality of micropores 2, and micropore 2 belows are provided with a pallet 3 moving up and down; When being full of metal liquid 4 in the micropore 2; Metal liquid 4 in the high-temperature crucible 1 can flow on the pallet 3 through micropore 2, and when in the micropore 2 when gassy or vacuum, metal liquid 4 can not flow on the pallet 3 through micropore 2 under surface tension effects.
The top of said high-temperature crucible 1 is provided with one and can moves up and down and be used for to micropore 2 injecting gas or metal liquid 4 or make the mobile converter 5 that becomes vacuum in the micropore 2.
High-temperature crucible among the present invention is a critical component; Its bottom is provided with the very little a plurality of micropores of spacing; Molten metal liquid slowly flows out downwards through micropore, and pallet moves down slowly simultaneously, and guide wire liquid solidifies the formation part; The horizontal section shape of part relies on the conducting of different micropores or closes and control, the made that high-temperature crucible is selected and molten metal does not soak into.Be in the micropore of closed condition and be full of air or vacuum, state keeps shut under the capillary effect of metal liquid always; Be in the micropore of conducting state and be full of metal liquid, the metal liquid in the high-temperature crucible is communicated with the not solidified metal liquid in part top, formation keeps connected state metal liquid passage always.
Certain is in the micropore of conducting state, in the time of need it being transformed into closed condition, through mobile converter; Make it aim at this micropore, drop to micropore and contact, and in micropore injection air or make micropore become vacuum; Remove mobile converter, this micropore will be in closed condition; In contrast, certain is in the micropore of closed condition, in the time of need it being transformed into conducting state; Through mobile converter, make it aim at this micropore, drop to micropore and contact; And in micropore, inject metal liquid, and remove mobile converter, this micropore will be in conducting state.
This device is through the control mobile converter, and the moving of pallet, and the flow of high-temperature crucible inner metal liquid body have been realized the model-free moulding of arbitrary shape part.
Forming method based on capillary model-free rapid molding device comprises the following steps:
A, metal liquid 4 is presented in the high-temperature crucible 1;
B, the break-make of micropore 2 is set; Let metal liquid 4 from micropore 2, pass through if desired; Then in micropore 2, inject metal liquid 4 through mobile converter 5; Interrupt passing through of metal liquid 4 in the micropore 2 if desired, then can be through mobile converter 5 injecting gas or make and become vacuum in the micropore in micropore 2;
C, metal liquid 4 flow on the pallet 3 through micropore 2; Move down pallet 3; Metal liquid 4 continues to flow down and constantly is cooled to and is part 6; Utilize the switch of the surface tension control micropore 2 of metal liquid 4, control the flow of metal liquid 4, the translational speed of pallet 3 simultaneously, make cooled part 6 form required shape.
Forming method of the present invention relates to and mainly contains several aspects; The one, the coordination of metal liquid flow in speed that pallet moves and the micropore; Guaranteeing the moulding of metal parts, is the temperature of metal liquid and the coordination of the medium of cooling gradually in addition, guarantees needed Temperature Distribution in the process of setting.So need well to confirm the speed that flow and the pallet of metal liquid through micropore moves.
The present invention is not limited to metal material, also can be other material, such as resin material etc.
Disclosed all characteristics in this specification except mutually exclusive characteristic, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
