Description
Technical field
The present invention relates to a kind of preparation method of ceramic part, particularly a kind of fast preparation method of ceramic part.
Background technology
Sintering, processing made after the classical production process of ceramic part was shaped by methods such as casting, injection forming, extrusion molding, hydrostatic pressings.Ceramic part with these method manufacturings generally needs to make earlier model and mould, only can make the part of simple shape, and manufacturing speed is slower, is difficult to realize accurate, quick and personalized the manufacturing.
Utilize rapid prototyping technique to produce ceramic part and can shorten the cycle greatly, raising speed.But also there are some problems in comparatively sophisticated at present rapid shaping technique, and for example, the ceramic membrane with the casting method preparation in the laminated entity manufacturing technology is the raw material production ceramic part, and its intensity is very low and following process is complicated; The fusion sediment forming technique is mixed ceramics powder and organic binder bond, squeezes silk, sintering then, and the shrinking percentage of the ceramic part of making is than the exclusion process complexity of big and organic binder bond.Other rapid prototyping technique such as stereolithography, select that the territory is laser sintered or the like to exist also that production cost is higher, the product distortion is bigger, and problem such as the ceramic part composition of making is single.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, propose that a kind of production cost is low, with short production cycle, the fast preparation method of the ceramic part of green non-pollution.
For achieving the above object, the preparation method that the present invention adopts is: the three-dimensional entity model that at first generates the ceramic part that needs manufacturing with 3D sculpting software in computer, with delamination software three-dimensional entity model is carried out layering then, be about to three-dimensional entity model and be divided into the thin layer that thickness is 0.1～2.0mm, obtain every layer shape; Ceramic mud is sprayed onto on the plaster mould and paves slurry with roller obtain the ceramic mud layer that thickness is 0.1～2.0mm; Shape according to the first layer three-dimensional entity model after the layering, on the thin layer for preparing, carve this layer skeletal lines with the taper-cut cutter head that has feeding tube, and outside skeletal lines, portray grid, the degree of depth of its portrayal is the thickness of this layer ceramic mud layer, injecting weight percent by the feeding tube on the taper-cut cutter head in the slit of portrayal simultaneously is the starch size of 40-50%, and wipe unnecessary ceramic mud and starch size off with scraper, form the first layer; On the first layer, spray ceramic mud once more and pave slurry and obtain the ceramic mud layer that thickness is 0.1～2.0mm with roller; Shape according to second layer three-dimensional entity model after the layering, on the thin layer for preparing, carve this layer skeletal lines with the taper-cut cutter head that has feeding tube, and outside skeletal lines, portray grid, the degree of depth of its portrayal is the thickness of this layer ceramic mud layer, injecting weight percent by the feeding tube on the taper-cut cutter head in the slit of portrayal simultaneously is the starch size of 40-50%, and wipe unnecessary ceramic mud and starch size off with scraper, form the second layer; Basis descends the shape of one deck to repeat the skeletal lines that sprays ceramic mud, carves three-dimensional entity model on the aspect of last layer successively, and portrays grid outside skeletal lines, with advancing in the slit of portrayal to inject starch size, obtains required three-dimensional prototype entity at last; At 200-280 ℃, soaking time was carried out drying in 40 minutes with the three-dimensional prototype entity that obtains, put into inherent 320-400 ℃ of baking oven after the drying, and soaking time was removed starch more than 1 hour; Three-dimensional prototype entity behind the removal starch is put into retort furnace, and at 700-950 ℃, soaking time is carried out biscuiting more than 0.5 hour, and clout after the biscuiting that three-dimensional prototype entity skeletal lines is outer is peeled off, and gets biscuit of ceramics; Biscuit of ceramics more than 1000 ℃, is incubated the ceramic part that gets final product requiredly more than 1 hour.
The sophisticated grout material of utilization of the present invention by repeating of ceramic slurry sprinkling-drying-cutting-starch joint filling-processes such as slip sprinkling, is accumulated as required ceramic prototype entity 3D shape, through sintering, makes the ceramic part of desired shape.Not only reduce production cost but also shortened the production cycle.
