A kind of processing technology of vintage silver cup

Abstract

The invention discloses a machining technology for a retro silver cup. The machining technology comprises the following steps of silver ingot stripping and slicing, melting, mold reversing, tempering,plate pressing, discharging, stretching, molding, annealing, pattern pressing, cleaning, retro treating and packaging. According to the machining technology for the retro silver cup, the machining technology is a novel technology researched and developed on the basis of combination of a traditional technology and a modern technology, and compared with the traditional technology, the aspects suchas patterns, lines and modeling are all greatly improved, the technology is suitable for large-scale production, the machining speed is high, the embossment effect is better highlighted, and the silver cup has the retro color and is fashionable, beautiful and exquisite in workmanship. Through the pattern pressing process and the retro treating process, the silver cup is more attractive in appearance and pure in color, the fashion sense is increased, and the good collection value is achieved; and the retro silver cup treated through the method is high in hardness and not prone to being deformed, has no chemical residue, and accords with the health maintenance concept of modern people.

Description

technical field

[0001] The invention relates to the technical field of silver cup processing, in particular to a processing technique for vintage silver cups. Background technique

[0002] The use of silver in medicine can be traced back to BC. The ancients knew that silver has the functions of accelerating wound healing, preventing infection, purifying water quality and keeping fresh and antiseptic. Silver has an excellent sterilizing effect. Common antibiotics can only act on 6 kinds of germs on average, but silver can eliminate 650 kinds of germs. Silver ions have a strong bactericidal effect and are very beneficial to the human body. Therefore, using silverware to store food can prevent the growth of bacteria and prolong the storage period of food. Chinese medicine uses silver to diagnose and treat related diseases, and Western medicine uses silver to treat ulcers. There are more than 100 years of records. Silver ions and compounds are toxic to some bacteria, viruses,...
