Abstract

The invention discloses a concentric sphere, especially to a ceramic concentric sphere manufacturing method and is characterized in that a traditional processing mode of engraving inward layer by layer is changed into a processing mode of engraving outwardly layer by layer. By the utilization of plasticity and engravability of a ceramic material green base substrate, a sphere and spherical surface-shaped housing of each layer are prepared; a hollow pattern designed is engraved; a spacer material is used to fill and support between layers; a material, the melting point of which is higher than porcelain-making temperature of the ceramic material, is used as a separating layer such that the layers will not be adhered to each other during high-temperature sintering of the ceramic concentric sphere in a kiln; and the spacer material can be removed out from the hollow place of the concentric sphere after the concentric sphere is sintered to form porcelain. Therefore, the ceramic concentric sphere with movable layers is obtained. According to the idea of processing outwardly layer by layer, different materials are changed, and the concentric sphere of different materials can be prepared simply by changing the technology.

Description

Homocentric sphere and manufacture method thereof

Technical field

The present invention relates to a kind of handicraft and make field, the particularly manufacture method of a kind of homocentric sphere and homocentric sphere.

Background technology

Traditional homocentric sphere generally is to make with materials such as ivorys.This homocentric sphere is made in layer to carve also inwards with the method for through-carved work every one deck is separated into the shelly sphere, accomplish that every one deck can both be movable, the more difficulty of the number of plies are larger, material hardness is higher, the larger also more difficult processing of fragility just can't process homocentric sphere such as materials such as potteries with said method.

Summary of the invention

Goal of the invention: technical problem to be solved by this invention is for the deficiency of existing homocentric sphere engraving technology, and a kind of method of successively outwards processing homocentric sphere, particularly concentric ceramic ball and other material homocentric sphere is provided.

Technical scheme: the concentric ceramic ball processing technique is the most complicated in various material homocentric spheres are made, difficulty is maximum, clear for setting forth, the spy comes the present invention is illustrated with the process of concentric ceramic ball in this programme, the homocentric sphere processing of other material only need be simplified some operations on this basis, slightly does just to change and can realize.Thinking of the present invention is: plasticity and the easy engraving property of utilizing the ceramic material green compact, make the dome shape housing of spheroid and every one deck, and with the designed pattern of through-carved work technique carve, fill with insolated layer materials between layers and support, the fusing point of insolated layer materials must be higher than the one-tenth porcelain temperature of ceramic material, so that the concentric ceramic ball between layers can adhesion during high temperature sintering in kiln, and insolated layer materials can also be taken out from the hollow part of homocentric sphere after homocentric sphere sinters porcelain into.Adhere to the insolated layer materials particle for fear of homocentric sphere ceramic surface when the high temperature, between ceramic layer and separation layer, apply again one deck high-temperature antisticking and lubricating paint to strengthen effect.

The present invention includes following steps:

Step 1, design is also made mould for the manufacture of homocentric sphere, die needed quantity treat as the bulbus cordis number of plies what and decide, every one deck ceramic layer and every one deck separation layer all need a secondary mould.The shape of each secondary mould is all similar, just varies in size.The principal character of mould all has a hemispheric hollow cavity for each part mould, makes the Ceramic Balls base substrate of every one deck and the hemispherical hollow cavity that the separation layer spheroid just in time can be put into mould;

Step 2 is got ceramic body material, isolated material and the adhesive of making homocentric sphere ready.The concentric ceramic ball can produce certain volume contraction through high temperature sintering the time, so the ceramic body material is necessary consistent with the shrinkage factor of isolated material;

Step 3 is produced the solid ceramic ball base substrate of innermost layer, and the required pattern of carve.

Step 4 is with Ceramic Balls billet surface coating one deck high-temperature antisticking and lubricating paint;

Step 5, after anti-stick coating is done, put into the Ceramic Balls base substrate in the hemispherical hollow cavity of one deck mould, the lower semisphere of Ceramic Balls base substrate is just in time inserted in the mould hemisphere cavity joint close, episphere exposes outside the mould.At this moment utilize mould or instrument to make the uniform shelly separation layer of one deck on the surface of first spheroid, the shell surface is the planar and spherical radius of smooth ball, and just in time the spherical radius with lower one deck mould is identical;

Step 6, take out the homocentric sphere base substrate of having carried out the semi-sphere separation layer and put into next secondary mould, to carry out this sphere of separation layer and just in time insert mould hemispherical hollow part down, first spheroid of Ceramic Balls base substrate exposes outside mould, makes the shelly separation layer of first spheroid with the previous step same method.At this moment, just intactly wrapped up the separation layer of one deck shelly outside the whole Ceramic Balls base substrate;

Step 7 is taken out the homocentric sphere base substrate from mould, repair the commissural burr of two hemispheres and uneven place, again with separation layer surface of shell coating one deck high-temperature antisticking and lubricating paint;

Step 8 after anti-stick coating is done, is reentered into the homocentric sphere base substrate in the last mould, makes episphere shelly ceramic body layer with the method for similar step 5, and at this one deck ceramic blank shell carve pierced pattern;

Step 9 is taken out the homocentric sphere base substrate and is put into next secondary mould, makes ceramic body shell and the carve pierced pattern of another sphere with the method for similar step 6.At this moment the complete parcel in whole separation layer outside one deck ceramic body sphere shell and engraving got well pierced pattern, expose following separation layer;

Step 10, take out the homocentric sphere base substrate, burr to commissure and depiction place places under repair, after bright and clean the correction of homocentric sphere surface, at whole homocentric sphere surface coating one deck high-temperature antisticking and lubricating paint, homocentric sphere base substrate has at this moment comprised one deck separation layer sphere shell and ceramic layer sphere shell;

Step 11 comes again step 5 to the operation of step 10, and the number of plies of homocentric sphere has just increased one deck.Multipass repeating step five to the operation of step 10 just can be made each ceramic layer and the separation layer of multi-layer concentric sphere, until make the homocentric sphere of the required number of plies.

Step 12 is put into suitable box alms bowl with concentric ceramic ball base and is placed high temperature furnace to sinter porcelain into.

Step 13 is taken out the concentric ceramic ball from kiln, the separation layer powder of interlayer is removed totally, and the making of concentric ceramic ball is namely accused and finished.

We can find out from above-mentioned homocentric sphere manufacturing process, in the completed concentric ceramic ball base substrate, its ceramic blank sphere shell and separation layer sphere shell are the homocentric sphere structures of isolating each other, just concentric ceramic ball layer has sintered porcelain into behind high temperature sintering, and separation layer is also uncompacted Powdered through becoming behind the high temperature, removes the separation layer powder and has namely obtained the concentric ceramic ball.If the solid section of concentric ceramic ball is made of insolated layer materials, just obtain the hollow concentric ceramic ball of core.Method of the present invention is illustrated as an example of pottery example.Ceramic process is comparatively complicated, and manufacture difficulty is also maximum, as use other material such as metal, cement instead, plastic or other material is made homocentric sphere, only needs to simplify some steps and changes a little design and just can realize, it is constant from inner outside thinking of successively processing.

Beneficial effect: use method of the present invention, just can solve the difficulty that to process with conventional method, process the homocentric sphere of the multiple materials such as concentric ceramic ball.
