Problems solved by technology

[0005] In view of the above problems, the purpose of the present invention is to provide a method for making uniform thick-walled cast tire cloisonné enamelware, so as to solve the problem of uneven firing time caused by uneven wall thickness in the production process of existing cast tire cloisonné enamelware. Simultaneous, local over-firing, local under-firing, casting tires and filigree need to be welded and assembled, resulting in problems such as glaze layer bursting, glaze layer discoloration, inclusion of air bubbles, and low production efficiency.

[0062] like figure 2 As shown, in the present embodiment, the cloisonné enamel device to be made is a kylin cast tire cloisonné enamel device, and the specific manufacturing method includes the following steps:

[0063] Step S1, according to figure 2 The structural form of the Kirin cast tire cloisonné enamel ware shown, the Kirin cast tire model is split into heads (such as image 3 shown), body (such as Figure 4 shown), tail (such as Figure 5 shown), legs (as Image 6 shown), angle (such as Figure 7 shown), a total of five model components. The positioning of two adjacent model components adopts the zigzag positioning method.

[0064] In step S2, the wall thickness of the cast tire blank is controlled at 4 mm, the thickness of the filigree wire is controlled at 0.2 mm, and the height is controlled at 0.7 mm. In order to facilitate wire casting, such as Figure 8 As shown, the filigree cross-sectional structure 1 is set as a trapezoid with a narrow top and a wide...

[0076] In the present embodiment, the cloisonné enamel device to be made is a cast tire cloisonné enamel belt button round box, and the concrete manufacturing method comprises the following steps:

[0077] In step S1, the round box model with buttons is divided into three model components: a bottom, a cover and a button, wherein the positioning of the bottom and the cover adopts a step-shaped positioning method, and the positioning of the button and the cover adopts a wave-shaped positioning method, and the disassembled part is used. Does not affect the filigree finish on the surface.

[0078] In step S2, the wall thickness of the cast tire blank is controlled at 2 mm, the thickness of the filigree wire is controlled at 0.15 mm, and the height is controlled at 0.5 mm. In order to facilitate the casting of the wire, the cross-sectional structure is set as a trapezoid with a narrow upper and a lower width, and the slope of the hypotenuse is 5°. Use digital modeling software to ...

[0089] In the present embodiment, the cloisonné enamelware to be made is a three-legged tripod-type furnace with cast tire cloisonné enamel, and the concrete manufacturing method comprises the following steps:

[0090] In step S1, the cast tire model is divided into multiple components such as a tripod body, ears and feet, and the positioning of the two adjacent components adopts a zigzag positioning method, and the disassembled parts do not affect the surface filigree decoration.

[0091] In step S2, the wall thickness of the cast tire blank is controlled at 5 mm, the thickness of the filigree wire is controlled at 0.25 mm, and the height is controlled at 0.5 mm. In order to facilitate the casting of the wire, its cross-sectional structure is set as a trapezoid with a narrow upper and a lower width, and the slope of the hypotenuse is 3°. Use digital modeling software to establish a 3D digital model of the cast tire, use the slicing tool to discretize the model, convert the fi...

Abstract

The invention relates to the technical field of enamel making, and discloses a method for making a cloisonné enamel device of a uniform thick-walled cast tire, which comprises splitting a cast tire model into two or more model components, and positioning each model component; The three-dimensional digital model of the casting tire is discrete, and the discrete model components are printed and formed; the model components are assembled to form a module, and the module is placed in the casting cylinder; the casting cylinder is filled with gypsum casting powder slurry; Put the casting mold into the roasting furnace for roasting; smelting the cast tire material to form molten metal, and use a negative pressure pouring device to pour the molten metal into the casting mold; after pouring, let it stand for a set time, and then quench the casting mold Enter the water for water blast cleaning, and clean the surface of the cast tire. After drying, the cast tire enamel with uniform wall thickness is obtained. In the present invention, the cast tire and the filigree are integrally cast and formed without welding and assembly, so that the cast tire wall thickness is uniform, the tire quality is dense, the filigree pattern is regular, and the wire thickness and height are uniform.

Description

technical field [0001] The invention relates to the technical field of enamel production, in particular to a method for producing a cloisonné enamel ware of a uniform thick-walled cast tire. Background technique [0002] Copper tire cloisonné enamel is a special handicraft made of thin flat copper wire, pinching out various patterns on the copper tire, and then filling the colorful enamel dots in the pattern, firing, grinding, and gilding. It has the artistic characteristics of elegant and powerful shape, complex and diverse patterns, crystal clear and moist appearance, and bright and eye-catching colors. Excellent art treasures that are known as the treasure house of world culture. Among them, the copper tire is the basis for making cloisonné enamel. According to its forming process, there are two types of forging and casting. The former is to cut copper sheets into various shapes according to the requirements of the drawings, and hammer them into various shapes of copper....
