Reverse electroforming process for jewelry processing

Abstract

The invention discloses a reverse electroforming process for jewelry processing, and relates to the technical field of jewelry processing, and the reverse electroforming process specifically comprises the following steps: S1, determining a product effect; s2, splitting a product structure; s3, reversely designing a product mold; s4, mold detection and finishing; s5, oiling and conducting; s6, electroforming; s7, post-processing is carried out; and S8, obtaining a finished product. According to the reverse electroforming process for jewelry processing, the mold is designed according to the final effect of product design, the ornamentation of the product is arranged on the inner surface of the inner cavity of the mold, and metal is thickened from inside to outside during attachment; due to the fact that the size of the ornamentation arranged on the inner surface of the inner cavity of the mold limits the size of the ornamentation after metal attachment, the surface effect of a formed product is greatly enhanced, namely details and expressive force of original design are reserved to the maximum extent, and the treatment energy of the ornamentation face on the surface of the product can be greatly reduced during later-period manual machining. And design damage and product expressive force damage caused by post-treatment are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of jewelry processing, in particular to a reverse electroforming process for jewelry processing. Background technique [0002] Electroforming is a process of electrodepositing metal on the surface of the mandrel, and then separating the two to make parts. The electroforming process has been widely used in the jewelry processing industry. At present, jewelry electroforming basically adopts the external method, that is, in Wax embryos or alloy embryos are used as prototypes to attach gold, silver and other metals on the surface to form handicrafts or ornaments. Specifically, in the electroforming working fluid, the pre-treated prototype is used as the cathode, and the electroformed gold, silver and other metals are used as the cathode. The anode, under the action of direct current, controls a certain current density, and after a certain period of electrodeposition, the metal electroformed product can be obtain...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a reverse electroforming process for jewelry processing, which solves the problem that the existing electroforming process using the external attachment method in the above-mentioned background technology is to carry out metal attachment on the surface of the embryo body. , the attached metal has a certain thickness, which will directly blur or even completely cover the originally possible small details, and make the three-dimensional modeling lines round and thick. For the expression forms with more surface details, the electroforming process is not suitable , and it is easy to cause the problem of changing the detail effect during the artificial processing in the later stage
