Problems solved by technology

Due to the characteristics of materials and production conditions, there are also certain restrictions on the design and appearance of glasses. For example, aluminum has a density of 2.7g / cm3, which is low in density and very light. Spectacle frames using aluminum need to increase its thickness to meet the strength requirements; stainless steel has good strength and hardness, but its density is 7.9g / cm3, which is relatively dense and difficult to process, so glasses with complex shapes The frames are rarely made of stainless steel; titanium, whose density is 4.5g / cm3, has a medium density, good strength, hardness and elasticity, but the process of making glasses with titanium materials is complicated and costly, and the process is much more complicated than ordinary aluminum-copper spectacle frames. , so it is generally positioned as a high-end spectacle frame will use titanium material
[0003] Chinese invention patent 02117293.5 discloses a preparation method of titanium-nickel composite wire for spectacle frames, which relates to a titanium-nickel composite spectacle frame, which has good strength and processing characteristics, but the overall density is still high, with nickel reaching 8.9g / cm3, the weight of the spectacle frame made of it is still very heavy. In addition, nickel is potentially dangerous to human health and can cause allergies or contact dermatitis. People who wear nickel metal spectacle frames are prone to dermatitis near the eyes. First, the skin is itchy. Then papules, herpes and erythema appear, and in severe cases, suppuration and ulceration

Embodiment 1

[0015] Such as figure 1 As shown, a metal composite spectacle frame includes a frame body 100, the frame body 100 is composed of double-layer metal layers, and the double-layer metal layers are metal titanium layer 1 and metal aluminum layer 2 sequentially from inside to outside. . The manufacturing process is: select metal aluminum plates with a thickness of 3-4mm and metal titanium plates with a thickness of 0.8-1.2mm, preferably 1mm, to form an aluminum-titanium double-layer metal composite board by welding, and an aluminum-titanium double-layer metal composite board After stamping, cutting, welding, grinding and other processing techniques, it is made into a metal composite spectacle frame with a thickness of 3-5mm, an outer surface made of aluminum, and an inner surface made of titanium. Aluminum is relatively soft, and titanium has high strength and good toughness. Compared with the same all-aluminum spectacle frame, the aluminum-titanium metal composite spectacle frame...

Embodiment 2

[0017] Such as figure 2 As shown, a metal composite spectacle frame includes a frame body 100. The frame body 100 is composed of double-layer metal layers. The double-layer metal layers are a stainless steel layer 3 and a metal aluminum layer 4 from the inside to the outside. The manufacturing process is: select a metal aluminum plate with a thickness of 3-4mm and a stainless steel plate with a thickness of 0.8-1.2mm, preferably 1mm, to form a stainless steel-aluminum double-layer metal composite board by welding, and the stainless steel-aluminum double-layer metal composite board is passed through Stamping, cutting, welding, grinding, polishing and other processing techniques are used to make a metal composite spectacle frame with a thickness of 3-5mm, an outer surface of aluminum, and an inner surface of stainless steel. Stainless steel has both toughness, elasticity and rigidity, while aluminum is relatively soft. Compared with the same all-aluminum spectacle frame, the st...

Abstract

The invention discloses a metal composite glasses frame and a manufacturing process thereof, and relates to the technical field of glasses frames. The metal composite glasses frame comprises a frame body, wherein the frame body is formed by compounding two metal layers, and the two metal layers can be arranged by two schemes, namely in the first scheme, a metal titanium layer and a metal aluminum layer are sequentially arranged from interior to exterior; in the second scheme, a stainless steel layer and the metal aluminum layer are sequentially arranged from interior to exterior. The metal composite glasses frame has the advantages that the strength and hardness are high, the subsequent manufacturing process of glasses is easy, the cost is lower, and the weight is lighter.

Description

technical field [0001] The invention relates to the technical field of spectacle frames, in particular to a metal composite spectacle frame and a manufacturing process thereof. Background technique [0002] At present, the common metal materials used in the eyewear industry in the world are pure titanium, titanium alloy, stainless steel, aluminum-magnesium alloy, beryllium copper, etc., and the same component uses a single metal material or a single alloy material. Due to the characteristics of materials and production conditions, there are also certain restrictions on the design and appearance of glasses. For example, aluminum has a density of 2.7g / cm3, which is low in density and very light. Spectacle frames using aluminum need to increase its thickness to meet the strength requirements; stainless steel has good strength and hardness, but its density is 7.9g / cm3, which is relatively dense and difficult to process, so glasses with complex shapes The frames are rarely made ...
