Production technology of silver plate inlaid with gold and combined die for same

Abstract

The invention relates to a production technology of a souvenir, namely a silver disc inlaid with gold pieces and a combined die for the production technology. The production method comprises the following process steps: processing a disc outline of the die; in a computer, designing the external dimension parameters of the silver disc and the matching curved surface of the plunger and cavity blockof the silver disc and adding raised patterns on the bottom surface or side surface of the silver disc die; arranging a groove on the circumference of the bottom surface of the silver disc plunger; punching to obtain the gold and silver blanks of the silver disc inlaid with gold; processing a die sleeve of the silver disc inlaid with gold; adopting two-step coining method: firstly coining a silver disc with gold piece preset positions and secondly coining gold pieces in the center of the silver disc to obtain the silver disc inlaid with gold. The silver disc inlaid with gold prepared by the production technology of the invention has stable quality and high qualification rate, and the production technology is also suitable for the production of other similar inlaid precious metal souvenirs.

Description

technical field [0001] The invention relates to a method for preparing a disk-shaped precious metal commemorative gift, in particular to a manufacturing process of a commemorative gift inlaid with gold pieces on a silver plate and a combined mold used in the manufacturing process. Background technique [0002] In the past, disc-shaped precious metal commemorative gifts were usually a single metal product of pure gold or silver, and the styles and colors of the products were limited. Its conventional production method is to produce qualified products through processes such as making a disc-shaped mold and embossing a flat cake, that is, a gold plate and a silver plate. However, with the development of the situation, it is necessary to produce gold-inlaid silver plates with more beautiful shapes and richer forms. However, due to the difficulty in designing the size of the silver plate and the gold plate, the different materials of gold and silver suppress each other. Combinin...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problems existing in the above-mentioned prior art, and provides a gold and silver disc inlay manufacturing process that can guarantee product quality, high pass rate, short processing cycle, and low production cost, and solves the problem of gold and silver disc in the prior art. The embossing process of the inlay is relatively complicated, the production efficiency is low, the gold plate and the silver plate are not firmly combined, and they are easy to fall off.
