Abstract
The invention discloses a kind of metal lattice material manufacturing method, metal lattice material manufacturing method of the present invention includes the following steps：1) paraffin is mixed with ceramic slurry, obtains ceramic mixed slurry；2) coated ceramic mixed slurry dries on volatility checker；3) volatile matter paraffin is removed by melting or evaporating after drying；4) then it is filled with liquid metal in empty mould, cooled and solidified simultaneously can be obtained porous metals lattice material after removing ceramic mold.The metal lattice material manufacturing method of the present invention can get the lattice material of large-size.
Description
Technical field
The present invention relates to metal lattice material manufacturing methods.
Background technology
The bearing structure purposes of hole foam metal material is limited by its elasticity modulus and intensity, and intensity is with density in finger
Number rule relationship, this makes it be inferior to the cellular material of same density significantly.Then, it is desirable to find with the more of other hole form
Hole body, this existing intensity index that can be comparable with honeycomb of novel porous structure, while open celled foam gold is had both again
The other functional attributes belonged to.This novel porous structure someone is referred to as " Lattice materials ", and also someone is referred to as " dot matrix material
Material ", they are the novel porous metal materials of one kind for having regular hole shape and hole in periodic arrangement.Still lack multilayer at present
, the manufacturing method of complicated metal lattice material.
Invention content
It is an object of the present invention to provide a kind of metal lattice material manufacturing methods, can be manufactured by this method multilayer, multiple
Miscellaneous metal lattice material.
The present invention is realized by following technological means：
A kind of metal lattice material manufacturing method of the present invention, includes the following steps：
1) paraffin is mixed with ceramic slurry, obtains ceramic mixed slurry；
2) coated ceramic mixed slurry dries on volatility checker；
3) volatile matter paraffin is removed by melting or evaporating after drying；
4) then it is filled with liquid metal in empty mould, cooled and solidified simultaneously can be obtained porous metals point after removing ceramic mold
Battle array material.
Further, paraffin described in step 1 and ceramic slurry are with 1：3 weight ratio mixing.
Further, coated ceramic mixing slurry again after the ceramic mixed slurry in step 2 in personality daughter to be evaporated dries
Material, obtains the multi-layer ceramics mixing slurry bed of material on volatility checker.
Beneficial effects of the present invention：The metal lattice material manufacturing method of the present invention, includes the following steps：1) by paraffin with
Ceramic slurry mixes, and obtains ceramic mixed slurry；2) coated ceramic mixed slurry dries on volatility checker；3) after dry
Volatile matter paraffin is removed by melting or evaporating；4) liquid metal is then filled in empty mould, cooled and solidified simultaneously removes ceramics
It can be obtained porous metals lattice material after mold.The metal lattice material manufacturing method of the present invention can get large-size
Lattice material.
Specific implementation mode
Below by way of specific embodiment to the detailed description of the invention：
A kind of metal lattice material manufacturing method in the present embodiment, includes the following steps：
Paraffin is mixed with ceramic slurry, obtains ceramic mixed slurry；The paraffin is with ceramic slurry with 1：3 weight ratio
Mixing.The coated ceramic mixed slurry first on volatility checker is removed volatile matter paraffin by melting or evaporating after dry
It removes, is then filled with liquid metal in empty mould, cooled and solidified simultaneously can be obtained porous metals lattice material after removing ceramic mold,
And the metal grid daughter is consistent with former volatile matter checker.The method can manufacture grid bulk, pyramidal structure checker, tetrahedron knot
Structure checker and 3D.Kagome structure checkers etc., can also manufacture increasingly complex molded non-planar.Moreover, with fast short-term training
The appearance of shape technology, checker casting may be implemented to automate.But by liquid metal the tortuous detour through path, Yi Jiyou
Casting flaw sensibility caused by this.
As a further improvement of the above technical scheme, the ceramic mixed slurry in step 2 in personality daughter to be evaporated dries in the air
Coated ceramic mixed slurry again after dry, obtains the multi-layer ceramics mixing slurry bed of material on volatility checker.
The skilled worker of the industry is it should be appreciated that the present invention is not limited to the above embodiments, above-described embodiment and explanation
Being only intended to described in book illustrates the principle of the present invention, and under the premise of not departing from the principle of the invention and range, the present invention is also
There can be various changes and modifications, these changes and improvements belong in scope of the claimed invention.
