Process for producing metallic translucent lens

Abstract

The invention a process for preparing metal light transmitting mirrors and relates to the process for preparing metal lens which have light transmitting effects. The process comprises selecting sheet metals for mirror faces, stamping the sheet metals into flat lens, using a shape-pressing die which is used to produce concave dies and convex dies to press invisible graph-texts on the positive surface of the lens or burn graph-texts on the negative surface of the lens through lasers, and producing the graph-texts which are same with the graph-texts on the positive surface of the lens on the negative surface of the lens or on carriers of the lens. The invention adopts mechanical moldings or laser techniques instead of handwork manufactures or casting techniques, the invention has the advantages that the manufacture of the light transmitting effects can be finished through forming by one step, the graph-texts can take various modes, the invention is convenient to manufacture precisely, the quality is stable, the imaging effect is clear, lens are light and durable, environmental pollution and resources consumption can be minimized, the lens can be combined with a plurality of carriers to produce different anti-counterfeit markings for jewelries, souvenirs, toys, teaching aids, handicrafts, commodities and the like, not only the graph-texts can be designed freely, but also image differences can be adjusted through adopting a laser technique, and the invention has strong randomness and wide applying range.

Description

Technical field [0001] The invention relates to a method for preparing a metal mirror with light-transmitting effect. Background technique [0002] There was a bronze mirror in the ancient Western Han Dynasty. The front of this bronze mirror is slightly convex, which can not only illuminate people, but also when strong light or concentrated light shines on the mirror surface, the reflected light will appear on the white wall or paper, and an image corresponding to the pattern on the back of the mirror will appear. , It seems to be reflected from the back of the mirror. Because people do not understand its mechanism very well, the patents applied for did not fundamentally solve the problem, such as "A Light-transmitting Bronze Mirror" (Patent No. 92244010), which is provided with a bronze mirror on the front of the mirror body. A concave image similar to the pattern on the back of the mirror or a concave image different from the back of the mirror can be kept at a certain angle wi...

Problems solved by technology

Because people's understanding of its mechanism is not very clear, so the patents that have been applied for do not fundamentally solve the problem, such as "a light-transmitting bronze mirror" (patent No. 92244010), which is provided with a mirror body front of the bronze mirror A concave image similar to the pattern on the back of the mirror or a concave image different from the back of the mirror can be kept at a certain angle with the light source when used, and the similar pattern on the back of the copper mirror can be reflected by light reflection. Although it points out that there is a concave image similar to the pattern on the back of the mirror on the front, there is no design method
