Enamel is regarded as a decorative material which replaces precious stones and is burned on a metal matrix to add colour to the metal piece. The completion of a piece of enamel requires a number of steps, in the traditional enamel making step, the step of applying enamel to the metal matrix is called "bluing", the tool for applying enamel to the metal matrix is usually a small shovel made of stainless steel or iron, and is called "blue gun", and the step of firing enamel is called "bluing". Wherein "blue" is the meaning of enamel.
The enamel technology is divided into metal-tyre enamel, ceramic-tyre enamel and glass-tyre enamel according to different carcasses. Wherein, the metal enamel consists of a metal matrix and enamel. The metal-work enamel process mainly comprises cloisonne enamel (cloisonn e), chisel enamel (champlev e), transparent enamel (basse taille), enamel (PAINTED ENAMEL) and window enamel (plique-atr-jour, also called light-transmitting enamel).
As one of the metal embryo enamel processes, open window enamel (plique-a-jour, also known as light-transmitting enamel) was produced in europe in the 13 th century. This traditional enamel process has been mainly used in the past for royalties and social noble. The enamel piece made by plique-a-jour process differs most from the other four metal-tyre enamel processes described above in that the metal tyre plique-a-jour is not a solid metal tyre but a frame (frame/cellular structure). In making plique-a-jour artwork, enamel tradesmen typically fills holes (cells/openings) in the metal frame with transparent enamel, and then fires multiple times until all the holes are filled. Due to the frame structure of the holes and the transparent enamel, the traditional enamel process presents a unique artistic effect of the mini church glass window under the irradiation of light. However, from ancient times, regardless of technology and pattern design changes, one of the most important features of this process has not been changed, namely the frame structure (cellular structure).

Detailed Description
The invention provides a process for manufacturing a three-dimensional structure enamel with orderly connected metal beads, which breaks through the concept of a traditional plique-a-jour metal frame, and the enamel is not a decorative coating attached to the surface of a metal tire or bound in the metal frame, but becomes a role of a connecting agent, and is sintered between two separated metal beads. By using the physical properties of the enamel material itself to join the orderly arranged metal beads in the space, the enamel product with a three-dimensional structure is obtained.
In particular, the method comprises the following steps,
Step 1, manufacturing a bracket; the support comprises a base and a plurality of metal columns, and the metal columns are sequentially fixed on the base according to the design;
Step 2, inserting metal beads perforated on the back into the metal column;
Step 3, enamel is applied to the gaps of the metal beads, and the metal beads are fired until all the metal beads are connected;
and 4, separating the enamel piece containing the metal beads from the bracket.
Among them, enamel selection is not particularly required, and the existing enamel with silicon dioxide as the main component is only needed. The enamel can be applied and fired by referring to the traditional enamel manufacturing process, and the enamel is filled into the gaps among the metal beads by adopting a blue gun, so that the enamel can be repeatedly applied and fired until the desired effect is achieved. Preferably, the main component of enamel is silica, with a melting point of 750 ℃, so that the firing efficiency is high and the firing effect is ensured.
In addition, preferably, the metal beads are made of pure silver (999 silver, the silver content is more than or equal to 99.9 percent), so that the adhesion between the enamel and the metal beads and the enamel can be better in transparency after being fired at high temperature; the metal posts are also preferably silver-containing because they are also in contact with the metal beads, but not with the enamel.
The fabrication of the stent is very important. First, the structure of the support determines the morphology of the enamel piece. Secondly, enamel parts are very fragile, the disassembly of the bracket determines whether the enamel parts can be obtained completely without breaking, and the manufacturing process of the bracket determines the difficulty in disassembly of the bracket. The materials of the bracket are affected to a certain extent by the manufacturing method of the bracket, such as a gypsum template method, a welding plate base and a metal substrate.
The plaster cast method, i.e. the stent, uses plaster cast as a base material to support the metal posts and enamel portions. The welding plate method, namely, a bracket uses a welding plate as a base material, and a metal column is inserted on the base to support the metal column and an enamel part; and the selective laser melting method refers to using a stent produced using a selective laser melting technique (SELECTIVE LASER MELTING), i.e., a metal 3D printing technique, as a base to support the metal beads and enamel portions.
Further description will be provided below in connection with specific examples.

Metal beads: 999 silver (pure silver), diameter: 3.0mm, backside punch diameter: 1.2mm
And (3) a bracket: titanium metal bracket
Manufacturing process
Referring to fig. 3, a process for fabricating a three-dimensional structure enamel of orderly connected metal beads, comprising:
step 1, manufacturing a bracket: modeling a bracket by using CAD, and then producing the bracket by using a metal 3D printer by taking titanium metal powder as a raw material, wherein the obtained bracket is shown in figure 3-a;
step 2, inserting metal beads perforated on the back into the metal columns, as shown in fig. 3-b;
step 3, enamel is applied in the gaps among the metal beads, firing is carried out as shown in fig. 3-c, and firing is repeated for a plurality of times as shown in fig. 3-d until all the metal beads are connected;
And 4, separating the enamel piece containing the metal beads from the bracket to obtain the enamel piece, as shown in fig. 3-e.
As can be seen in connection with the above examples 1-3, the fabrication of the stent is very important. First, the structure of the scaffold determines the morphology of the enamel member, and the scaffold of the present invention may have other forms in addition to the scaffold forms of examples 1 to 3, as shown in fig. 8; secondly, enamel parts are very fragile, the disassembly of the bracket determines whether the enamel parts can be obtained completely without breaking, and the manufacturing process of the bracket determines the difficulty in disassembly of the bracket.
The plaster mold method and the welded plate method are quick and convenient to manufacture, the equipment requirement is low, and the enamel piece can be easily separated from the bracket by dissolving the plaster mold of the base, but the two methods mainly adopt manual operation, so that accurate data and modeling are difficult to obtain; in addition, the plaster mold is easy to break in the firing process, so that the metal column is displaced; meanwhile, in the firing process, dust generated by the plaster mold is attached to the surface of the metal beads, so that the adhesion degree of enamel and the metal beads is reduced, and the enamel is broken. The welded plate method is used as a welding plate of a base material, is solid and cannot be dissolved in water, and the separation process needs to pay attention to that the generated external force easily causes the enamel piece to break.
The selective laser melting method can collect accurate data by constructing accurate metal scaffolds, and provide basic parameters for subsequent modeling design. Thus, it is preferably produced by a selective laser melting method. The process parameters are further optimized in the following in connection with the examples.
Example 4 horizontal distance experiment between metallic beads
Referring to example 3, as shown in fig. 4, a horizontal base was fabricated, on which a plurality of metal posts P1, P2, P3, P4, P5, P6, P7, P8, P9 were arranged in parallel, the height of the fixed metal posts was 19.8mm, two adjacent metal posts were a group, G1, G2, G3, G4, G5, G6, G7, G8, the distance between the two adjacent metal posts was varied in sequence, the diameter of the metal beads was 3.0mm, enameling and firing were applied for 3 to 5 times, respectively, and the maximum horizontal distance of the bondable metal beads on the same horizontal line was evaluated. The specific experimental parameters are shown in table 1.
TABLE 1 horizontal distance experiment between metallic beads
EXAMPLE 5 experiment of the height difference between Metal beads
Referring to example 3, as shown in fig. 5, a horizontal base is fabricated, on which three sets of metal columns are arranged in parallel, each set of metal columns consisting of two columns, a reference column and an experimental column; wherein group 1 (P1 & P1), group 2 (P2 & P2), group 3 (P3 & P3) were fixed 19.80mm with reference to column height, the experimental column height was changed, the height difference of the metal beads was adjusted, and the distance between the two columns was fixed to be 4.20mm; the metal beads were 3.0mm in diameter, enamelled and fired 2-4 times, respectively, and the maximum height difference of the bondable metal beads was evaluated. The specific experimental parameters are shown in table 2.
TABLE 2 experiments on the height difference between metal beads
In connection with the above examples 4-5, it can be seen that in the preparation process of the examples according to the invention, enamel frit is applied using a blue gun, the maximum distance between two metal beads (diameter: 3.0 mm) that can be joined being 2.4mm. The greater the distance between the two metal beads, the greater the number of applications and firing of enamel required. Firing times: 3-5 times.
In the case of two metal beads (diameter: 3.0 mm) at a horizontal distance (4.2 mm), enamel frit was applied using a blue gun, and the maximum height difference between the two metal beads that could be joined was 2.0mm. The greater the difference in height between the two metal beads, the more difficult it is to control the application and firing of the enamel. Because, the larger the height difference, the more easily the enamel flows and sticks to the bottom of the higher metal beads, resulting in the metal beads not being separated from the metal scaffold after firing. Thus, it is desirable to control the amount of enamel applied each time. Firing times: 2-4 times.
EXAMPLE 6 Corrosion separation
Materials and parameters
Enamel: the main components are as follows: vitreous inorganic silica (glassy inorganic silica); melting point: 750 DEG C
Metal beads: 999 silver (pure silver), diameter: 3.0mm, backside punch diameter: 1.2mm
And (3) a bracket: red copper base and 999 silver metal column
The manufacturing process comprises the following steps:
referring to FIG. 6, a process for fabricating enamel with three-dimensional structure comprising sequentially binding metal beads
Step 1, manufacturing a bracket: welding a red copper base (a main shaft) and 999 silver metal columns into a bracket, and inserting metal beads with holes on the back into the metal columns;
step 2, enamel is applied in gaps among the metal beads, and firing is carried out until all the metal beads are connected;
step 3, after the enamel is burned, soaking a main shaft part of the metal scaffold in a ferric trichloride corrosion pool with the concentration of 10%;
step 4, reacting the ferric trichloride solution with red copper, wherein the red copper base part of the bracket is corroded;
step 5, after 24-36 hours, the base is corroded clean, and a schematic view of the corroded bracket is shown in FIG. 7;
and 6, removing the metal column from the enamel piece to obtain the enamel piece.
In connection with the above examples 1-3, it can be seen that when the enamel member and the bracket are separated, if the bracket is insoluble in water, the fragile enamel member is easily damaged by the separation by external force, and thus in connection with example 6, it is considered to divide the separation into two parts, namely, the separation of the base and the metal posts, and the separation of the metal beads and the metal posts. The top end of the metal column is designed into a cone shape, and the contact point between the metal column and the metal bead is small, so that the separation of the metal bead and the metal column is facilitated; the base and the metal column are separated by ferric chloride corrosion, so that the enamel part is not damaged by external force. When the base is red copper, the enamel containing the metal beads is separated from the support by ferric chloride etching, so that the metal beads (999 silver) and enamel portions are not affected, preferably, the ferric chloride solution is 10% in concentration, and the etching time is 24-36 hours. Preferably, the proportion of red copper is reduced in the metal columns of the support. Because copper oxide (black) is generated in the firing process, the copper oxide is easy to fall on the surface of the metal beads, so that the adhesion degree of enamel and the metal beads is reduced, the enamel piece is broken, and the appearance of a product is influenced. Therefore, the material of the metal posts is preferably 999 silver, and the material of the metal main shaft connecting the metal posts is preferably red copper. Therefore, when designing and producing the metal bracket, the selective laser melting method and the acid corrosion method can be combined, so that not only can the accurate preparation be obtained, but also the separation of the enamel piece and the bracket is convenient, and the yield is improved.
In summary, the invention provides a process for manufacturing a three-dimensional enamel with orderly connected metal beads, which uses the physical properties of enamel materials to connect the orderly arranged metal beads in space to obtain an enamel product with a three-dimensional structure, and the obtained enamel product has special holes and projection effects, thereby enriching the expression forms of the enamel product. An illustration of a three-dimensional structure of enamel products of ordered bonded metallic beads obtained by the fabrication process of the present invention is provided in FIG. 9.
The improvement of the manufacturing process of the invention relative to the prior art is mainly represented by the following aspects:
First, from the material aspect, the traditional understanding of enamel manufacture is changed, and enamel is not used as a decorating material only, but also used as a bonding agent to serve the function of bonding metal pieces in a space.
Secondly, the relation between enamel and metal parts is changed from the aspect of structure. In the past enamel was fixed in a metal frame of a specific shape, which was the main structure. Enamel does not play a major role in terms of force and structure. In the products produced according to the invention, the enamel and the metal part act as the same important forces and are an integral part of the structure. In the past, metal frames have been considered as a complete article even without the application and firing of enamel. In the new art, however, the metal part cannot leave the enamel and is present alone.
Third, from the manufacturing process aspect, in the past, the act of applying enamel was described as filling enamel into a metal frame. In the present invention, enamel is filled into the gap between two metal pieces.
Fourth, from the visual effect aspect, the manufactured enamel product has brand new visual effect, and the visual language of 'orderly arranged but different porous holes'. Although, similar pore effects were seen in the traditional plique-a-jour enamel. Enamel tradesmen does not apply enamel in a specific metal frame, but creates the effect of holes. The pore effect produced by the present invention differs most from that of traditional enamels in that in the past that pore effect was a definite, predictable result, determined by the shape of the fixed metal frame. The hole effect created by the new technique is a special effect formed by the flow and shrinkage of enamel after melting, and different hole effects are generated because of different firing temperatures and enamel application amounts. Meanwhile, under the irradiation of light, the product manufactured by the new technology can also generate a special projection effect (figure 9).
Fifth, from the application aspect, the enamel product of the invention has new visual effect, and can be widely applied to ornaments, artworks and indoor space display designs. The elements added with light can be considered in design, and the visual effect of the invention can be maximally presented. The application of the technology can add more abundant expression forms for the enamel technology.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
