Problems solved by technology

[0002] At present, most of the surface patterns of silver products on the market are made by hand, mold stamping, mechanical nailing and sanding, etc. Using this method to produce patterns on the surface of metal silver, the bottom layer other than the patterns can be set off to produce snowflake-like bright spots or bright stars. , the product is more exquisite, more ornamental and collectible, but the processing speed is slow, the production efficiency is low, and the antioxidant capacity is poor
Chinese patent document CN201811103827.X discloses a method for making snowflake silver handicrafts and ornaments produced by electrolysis. A layer of snowflake crystals will be adsorbed on the outer surface of the silver products produced by this method, which improves the processing efficiency to a certain extent, but the production The process is complicated, the processing cost is high, and snowflake crystals cannot be formed on the inner surface of silver products at the same time, and the anti-oxidation ability still needs to be improved

Embodiment 1

[0022] The invention provides a kind of processing method with the silver product of snowflake crystal surface, comprises the following steps:

[0023] (1) Material selection: The raw material of the processed silver products is the national standard No. 1 silver plate, the silver purity is greater than or equal to 99.99%, and the national standard No. 1 silver plate is used to improve the processing efficiency, and the effect of producing snowflake crystals is better;

[0024] (2) Forging: use a forging press to forge the silver plate selected in step (1), so that the thickness of the forged silver plate matches the processing specifications of the silver product, which is convenient for the shape design of the silver product;

[0025] (3) Modeling: Extrude the forged silver plate with a forming machine to produce silver products of different specifications that meet market demand;

[0026] (4) Grinding: Grinding the inner and outer surfaces of the shaped silver products to e...

Embodiment 2

[0030] The present invention provides a processing method for silver products with a snowflake-like crystal surface. Change the set temperature in step (6) of Example 1 to 900°C, and when the temperature in the electric heating furnace reaches 900°C, turn on the Furnace door Put the silver products into the electric heating furnace, close the furnace door and heat again to keep the furnace temperature at 900°C for about 5-10 minutes, so that the inner and outer surfaces of the silver products turn white and snowflake-like crystals appear, continue heating for 3~ In 5 minutes, the snowflake-like crystals on the inner and outer surfaces of silver products will be more evenly distributed, the color will be brighter, and it will present a three-dimensional effect, and the anti-oxidation time of the product surface will be extended.

Embodiment 3

[0032] The present invention provides a processing method for silver products with a snowflake-like crystal surface. Change the set temperature in step (6) of Example 1 to 960°C, and when the temperature in the electric heating furnace reaches 960°C, turn on the Furnace door Put the silver products into the electric heating furnace, close the furnace door and heat again to keep the furnace temperature at 960°C for about 5 minutes, so that the inner and outer surfaces of the silver products present evenly distributed snowflake-like crystals that emit blue light, and the color is gorgeous , and has a strong three-dimensional sense. Under this condition, the processing time of the product is short, the production efficiency is high, and the anti-oxidation time of the surface of the silver product is long.

[0033] The working principle of the present invention is that the silver products processed by the national standard No. 1 silver plate are selected and fired under specific h...

Abstract

The invention belongs to the technical field of silver product processing, and relates to a processing method of a silver product with a snowflake-shaped crystal surface. The method comprises the following steps of 1) selecting a silver material with the purity of more than or equal to 99.99 percent as a raw material of a processed silver product; 2) forging and pressing the silver material selected in the step 1) by adopting a forging press; 3) extruding and molding the forged and pressed silver material by adopting a molding machine; 4) polishing the surface of the silver product; 5) performing mirror polishing treatment on the surface of the silver product by adopting a mirror polishing machine; and (6) placing the silver product in an electric heating furnace to be heated, wherein theheating time ranges from 5 min to 20 min, the heating temperature ranges from 850 DEG C to 960 DEG C, so that the snowflake-shaped crystals are generated on the inner surface and the outer surface ofthe heated silver product. According to the method, the snowflake-shaped crystals can be generated both on the inner surface and the outer surface of the silver product, and the generated snowflake-shaped crystals are uniform in distribution, bright in color, long in antioxidant time, short in processing time, high in efficiency and low in cost.
