Problems solved by technology

[0002] Due to its vivid image and high-end atmosphere, Pakistani copper handicrafts are mostly used in high-end hotels, company conference halls and high-end residential decorations. They are gorgeous and elegant, and can also be used for home decoration and craft collection. There are many kinds of crafts, and thousands of varieties can be produced. Due to the high melting point of copper and the influence of casting performance, it is difficult to achieve high casting precision. The price and production cycle are long, and the existing copper product manufacturing process mainly has the following problems:
[0003] 1. Due to the poor grasp of the mass fraction percentage of copper and other metals, the processed copper handicrafts are easy to change color and easy to be oxidized
[0004] 2. Due to improper production process, copper handicrafts often have problems such as size deformation, trachoma, air bubbles, etc., a large amount of repairs and even a high scrap rate
[0005] The above problems have seriously affected product quality and production costs, causing unnecessary waste and economic losses to copper handicraft processing enterprises

Embodiment 1

[0023] A kind of manufacturing method of copper handicraft described in the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0024] (1) Smelting and melting copper: put 1.5kg of copper, 0.2kg of tin, 0.24kg of lead and 0.06kg of aluminum in a smelting ladle, then place the smelting ladle on a charcoal stove for melting, when the temperature reaches 1083°C When left or right, the copper ingot is melted into copper water to prepare a copper-water mixture for casting; the abrasive mold cast at this ratio is soft and hard, suitable for carving, and the copper thorns are easy to fall off.

[0025] (2) Sand table casting: according to the shape of the parts to be cast, select an appropriate sand table filled with fine sand, press out the shape of the casting parts on the sand table, and paint the surface with paraffin, so that the abrasive will not produce product bubbles , seal the sand table, pour the copper-water mixture into the sand...

Embodiment 2

[0035] The embodiment of this embodiment is basically the same as that of Embodiment 1, the difference is that when smelting molten copper in Step 1, 1.44 kg of copper, 0.16 kg of tin, 0.2 kg of lead, and 0.02 kg of aluminum are added to the smelting spoon. kg.

Embodiment 3

[0037] The embodiment of this embodiment is basically the same as that of Embodiment 1, the difference is that when smelting molten copper in Step 1, 1.56 kg of copper, 0.24 kg of tin, 0.28 kg of lead, and 0.1 kg of aluminum are added to the smelting spoon. kg.

Abstract

The invention discloses a fabrication method of copper crafts. The copper crafts are refined by eight procedures of smelting and melting copper; casting a sand table; welding accessories; polishing, trimming, finishing and plating; marking off and engraving; engraving designs, and spraying baking finish and molding. The mass fraction percent of copper and other metals is reasonably set, so that the processed copper crafts do not change in color, and are not easily oxidized at the same time. By adopting the procedures, the problems of size deformation, air shots, air bubbles and the like of the crafts are completely eradicated effectively, the repair amount and the defective index of the crafts are reduced, meanwhile, the quality of the crafts is improved, and the production cost is reduced.
