A kind of polishing machine of 3D printing product
Technical field
A kind of polissoir of 3D printing is the utility model is related to, particularly a kind of polishing machine of 3D printing product.
Background technology
3D printing technique is one kind of RP technique, and based on it is a kind of mathematical model file, utilization is powdered
Metal or plastics etc. can jointing material, come the technology of constructed object by way of successively printing.Past its often Making mold,
The fields such as industrial design are used for modeling, are now increasingly used for the direct manufacture of some products.Particularly some high values
Using(Such as hip joint or tooth, or some airplane components)There are the parts formed using the printing of this technology.“3D
Printing technique " means the popularization of this technology.It is multiple that 3D printing technique is related to information technology, material science, precision optical machinery etc.
Aspect, increasingly there is competitiveness in current manufacturing industry, therefore be referred to as " manufacturing technology with the industrial revolution ".3D printing
Technology includes the technologies such as fused glass pellet, selective laser sintering, stereolithography apparatus, has expanded material shaping significantly
Method, for can not be by the procedural material of melt-processed, 3D printing technique be a kind of good solution party
Case.
To improve the surface flatness and finish of 3D printing macromolecule product, generally use polissoir and polishing machine pair
3D printing product carries out sequent surface retrofit, and existing surface polishing mode mainly includes:(1)Sand paper is polished, and is beaten by hand
Mill uses resinder sanding and polishing, but this kind of polishing mode is difficult to handle small product, and grinding efficiency is low, time-consuming,
And the different degrees of destruction of product can be caused, reduce printing precision;(2)Bead-blast is high towards polishing product using nozzle
So as to be polished, this method damages fast abrasive blasting to the surface of product, it is impossible to accomplishes unusual light, it is same to expend the time
Sample is longer;(3)Steam fumigating system, 3D printing product is placed in the vapor can of high polymer material good solvent, utilizes steam-melting
Product surface is so as to reach smooth effect, and compared to above two methods, steam fumigating system is simple to operation, and cost is low, polishing
Effect is good, use easy to spread.
In order to realize that steam fumigating system is polished, current vapour polishing equipment can typically set the cover of a sealing
Body, whole equipment can be sealed in vapour polishing, when needing to take thing, cover body is opened, but such structure is held at present
It is easily caused when taking thing, steam state polishing sovent diffusion easily spreads, and influences the polishing to next product, causes finally to polish
Effect is deteriorated.
Utility model content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art and providing a kind of machine can lift, no
Polishing product is taken out with translucent cover can is removed, reduction removes steam state caused by translucent cover and polishes sovent diffusion, final shadow
The problem of ringing polishing effect next time, while a kind of more preferable polishing machine of 3D printing product of polishing effect.
To achieve these goals, the polishing machine of a kind of 3D printing product designed by the utility model, the pedestal bag
