Problems solved by technology

The production of this kind of concentric sphere must be carved inward layer by layer with the method of hollow carving, and each layer is separated into a shell-shaped spherical surface, so that each layer can move. The more layers, the more difficult it is, and the higher the hardness of the material. , the greater the brittleness, the more difficult it is to process, such as ceramics and other materials, it is impossible to process concentric spheres with the above method

Embodiment Construction

[0032] As shown in the figure, the present invention discloses a processing method for making ceramic concentric spheres, comprising the following steps:

[0033] Step 1: Design and make mold 1 for manufacturing concentric spheres. The number of molds required depends on the number of layers of concentric spheres. Each layer of ceramic layer and each layer of isolation layer requires a pair of molds. Each pair of molds is similar in shape, only different in size. The main feature of the mold 1 is that each mold has a hemispherical hollow cavity, so that the ceramic ball green body and the isolation layer spherical body of each layer can just be put into the hemispherical hollow cavity of the mold 1;

[0034] Step 2, prepare the ceramic body material, isolation material and anti-adhesive material for making the concentric sphere. Ceramic concentric spheres must be sintered at high temperature, so the shrinkage rate of the ceramic body material and the isolation material must b...

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

technical field [0001] The invention relates to the field of handicraft manufacturing, in particular to a concentric sphere and a method for manufacturing the concentric sphere. Background technique [0002] Traditional concentric spheres are generally made of ivory and other materials. The production of this kind of concentric sphere must be carved inward layer by layer with the method of hollow carving, and each layer is separated into a shell-shaped spherical surface, so that each layer can move. The more layers, the more difficult it is, and the higher the hardness of the material. , the greater the brittleness, the more difficult it is to process. Materials such as ceramics cannot be processed into concentric spheres by the above method. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by this invention is to provide a method for outwardly processing concentric spheres layer by layer, especially ceramic concentric sphere...
