Problems solved by technology

Commonly used materials such as stainless steel and alloy steel used in the prior art are often prone to allergies, and have poor environmental corrosion resistance, and are prone to corrosion and rust
[0005] 2. Overall processing of metal spectacle frames
The processing of metal spectacle frames is relatively complicated, so the metal spectacle frames in the prior art are mostly processed separately from the nose bridge structure, lens ring and pile head, and then welded together. Strong, it is easy to cause the welded part to crack when it is impacted or dropped by an external force, and it cannot be repaired
[0006] 3. The problem of processing the inner groove of the mirror ring in the metal spectacle frame
In the actual processing of the metal mirror frame, since the grooves required inside the mirror ring are shallow and thin, the mirror ring after the initial molding needs to be processed by machinery (such as CNC) to make the grooves in the mirror ring conform to The assembly requirements of the lens are very time-consuming and labor-intensive, and the cost remains high

Abstract

The invention discloses an amorphous alloy spectacles frame. A spectacles frame main body comprises a nose bridge structure, lens circles and pile heads and is integrally formed; the two sides of the spectacles frame and the pile heads have non-closed structures; each of the non-closed structures comprises an upper part and a lower part; the upper parts and the lower parts can have elastic deformation under the effect of external force; grooves matched with lenses are formed in the inner sides of the lens circles. The spectacles frame provided by the invention is made of amorphous alloy with high performance. With a manufacture method fit for the property of amorphous alloy raw material, the manufacture technique is greatly simplified, the manufacture cost is lowered, and the spectacles frame is excellent in appearance and is firm and durable.

Description

technical field [0001] The invention relates to the application of the amorphous alloy, in particular to a spectacle frame made of the amorphous alloy and a preparation method thereof. Background technique [0002] The spectacle frame is an important part of the spectacle, which mainly plays the role of supporting the spectacle lens. At present, there are various materials of spectacle frames on the market, mainly including metal, plastic, resin, carbon fiber and other materials. With the change and improvement of people's aesthetic concept, spectacle frames made of metal materials with a sense of modern technology have been widely favored by consumers. [0003] Compared with traditional plastic frames, metal spectacle frames have many excellent properties, such as stylish appearance, higher strength, harder and more durable, more resistant to falling and impact, and more resistant to environmental corrosion. However, due to the limitation of raw materials and processing t...
