Annealing and shaping process of special-shaped thin-wall copper tire cloisonne enamel ornament

Abstract

The invention discloses an annealing and shaping process for a special-shaped thin-wall copper tire cloisonne enamel ornament, which is used for annealing and shaping a tire body subjected to bluing treatment each time, and comprises the following specific operation steps: taking out the roasted tire body, performing air cooling to 600 +/-30 DEG C, then putting the tire body into a mold cavity of a lower mold in a pre-heated shaping mold, and then putting the mold cavity into a mold cavity of a lower mold in the shaping mold, so as to obtain the cloisonne enamel ornament. And adjusting the field angle of a lower mold cavity in the shaping mold to be 1-2 degrees larger than the field angle of the corresponding tire body, closing the upper mold and the lower mold of the shaping mold to shape the tire body, naturally cooling the tire body along with the mold, and demolding and taking out the tire body. According to the implementation of the invention, the special-shaped thin-wall silicon enamel decoration piece becomes a controllable unit body, so that the size is changed into the size and the complexity is changed into the simplicity according to the design requirements of different clock shells, the fragmentation combination is realized, the manufactured enamel decoration pieces can be respectively assembled on the corresponding decoration sites on the outer surfaces of the clock shells in a matched manner, and then the decoration sites are integrated; the assembly qualified rate is improved from 40% to 80%, and industrial batch production is achieved.

Description

technical field [0001] The invention relates to the technical field of arts and crafts, in particular to an annealing and shaping process for a special-shaped thin-walled copper tire filigree enamel ornament. Background technique [0002] As the intangible cultural heritage of the Chinese nation, cloisonne enamel products are a systematic project integrating metallurgy, casting, painting, kiln industry, carving, appraising, hammering and other technologies. In order to excavate the ancient cultural heritage of my country's watch industry, we have cooperated with the Palace Museum to imitate the cloisonné clock. After structural analysis, it mainly has the following two typical structures: figure 1 and figure 2 shown. figure 1 The type of cloisonné enamel self-ringing bell, the shape is selected from the classic tribute utensils, its copper body is generally made of copper casting into a thicker copper body, and the pattern is conceived according to the pattern, the outlin...
