Problems solved by technology

The existing jewelry processing technology uses molten gold with a purity of more than 999.994‰ as a raw material, but in the process of processing jewelry, the purity of molten gold is usually lost, resulting in the purity of the gold jewelry produced can only reach 99.99%. Manufacturers cause economic losses and cannot meet the needs of consumers

Embodiment 1

[0026] A process for processing oil pressure gold jewelry with a purity of 999.99‰, the steps are as follows:

[0027] (1) Raw material melting gold: take high purity gold with a purity of more than 999.994‰ as the raw material, melt the high purity gold in the graphite pot of the high frequency furnace, pour it into the baked graphite tank, and use titanium for the gold in the graphite tank The clamp is put into strong hydrochloric acid for acid frying;

[0028] (2) Oil pressure: a. Beading: press the gold material of step (1) into a long bar with a wire press to obtain a gold bar;

[0029] b. Pressing and overheating: press the gold material of step (1) into a strip with a pressing machine. After obtaining the gold bar, press the pressed gold bar into a sheet with a tablet press to obtain the gold piece. Gold flakes burn red; among them, every time a gold bar passes through the tablet press, scrub the tablet press with ethanol once;

[0030] c. Put the gold bars of step a and the g...

Abstract

The invention belongs to the field of jewelry machining and in particular relates to a machining process of oil pressing type gold jewelry with the purity of 99.999 percent. According to the machining process, raw materials are subjected to steps of melting, oil pressing, molding, polishing, sanding, embroidering, press polishing and quality checking and the cleanliness of an environment is regarded in a preparation process; steel and iron type tools used in a technological process are replaced with a special diamond type tool; a condition that the tool reacts with gold so that the loss of the purity of the gold is caused is avoided, and the gold jewelry with the purity of 99.999 percent is prepared; the quality, purity and ornamental property of the gold jewelry are greatly improved and user experience is improved.

Description

Technical field [0001] The invention belongs to the field of jewelry processing, and particularly relates to a processing technology of oil pressure gold jewelry with a purity of 999.99‰. Background technique [0002] With the improvement of people's living standards, people's desire to buy gold jewelry is increasing, and the requirements for the appearance, purity and quality of gold jewelry are also increasing. The existing jewelry processing technology uses molten gold with a purity of more than 999.994‰ as raw material. However, during the processing of jewelry, the purity of molten gold is usually lost, resulting in the purity of gold jewelry only reaching 99.99%. The manufacturers cause economic losses and cannot meet the needs of consumers. Summary of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a processing technology of oil pressure gold jewelry with a purity of 999.99‰. [0004] The technical solution...
