Embodiment 1

[0019] A kind of processing method of spectacle frame, described production method comprises the steps:

[0020] 1) Injection molding: heating and softening cellulose acetate, pouring it into the mold for vacuum casting, the heating temperature is 200°C, and the temperature inside the mold is 50°C, with high degree of automation and low cost, suitable for mass production;

[0021] 2) Remove burrs: Use liquid nitrogen freezing technology to embrittle the obtained blank spectacle frames, and at the same time, spray a granular metal with a diameter of 1.5mm at a speed of 30m / s to hit the burrs of the product, which can not only achieve high efficiency, High-quality flash removal can ensure that all properties and characteristics of the product itself do not change;

[0022] 3) Grinding and polishing: the spectacle frame after removing the flash is polished with alumina micropowder with a diameter of 25nm, and the polishing time is 40min, which can make the spectacle frame more sm...

Embodiment 2

[0027] The rest is the same as that of Example 1, except that the plastic in step 1) is butyl acetate, and the polymer particles in step 2) are hard plastic projectiles.

Embodiment 3

[0029] The rest are the same as in Example 1, except that the emission velocity of the particles in the step 2) is 45m / s, the polishing powder in the step 3) is a mixture of calcium carbonate, oil and paraffin, and the polishing time for 50min.

[0030] In the above three embodiments, the obtained spectacle frames are light in structure, beautiful and wear-resistant, and weigh 60% to 80% of the weight of ordinary spectacle frames, which can bring good comfort to users, and are suitable for mass production. The cost is low, which is conducive to the sales and promotion of products.

[0031] According to practical application, in the production and processing of spectacle frames, the plastic is heated and softened, and injected into the mold for vacuum casting, which has a high degree of automation and low cost, and is suitable for mass production. The products are frozen by liquid nitrogen freezing technology to make them embrittled. At the same time, a high-speed injection of...

Abstract

The invention discloses a spectacle frame processing method. The spectacle frame processing method comprises injection molding, burring, polishing, assembling combination, examination and ink-jet printing. The spectacle frame processing method has a high automation degree and a low cost, is suitable for batch production, utilizes a liquid nitrogen refrigeration technology to freeze a product so that the product is embrittled, has a process of jetting polymer particles to burr of the product at a high rate so that high-efficiency high-quality burring is realized and product characteristics are not changed, utilizes a polishing process to make the spectacle frame flat and smooth so that good feel is obtained, utilizes the examination process to ensure if the spectacle frame size is qualified so that a rejection rate is reduced, and utilizes the ink-jet printing process for jet-printing spectacle frame specification and trademark on spectacle legs so that product postmarketing maintenance and spectacle frame brand publicity are promoted.

Description

technical field [0001] The invention belongs to the field of spectacle processing, and in particular relates to a processing method of spectacle frames. Background technique [0002] Glasses are a tool commonly used by people, used to adjust eyesight, add decorations, etc., generally include lenses and frames, the quality of the frame directly affects the comfort of the user, so the manufacturing and processing methods of the frame are particularly important. important. The Chinese patent No. 201010211353.8 discloses a plastic mirror frame processing technology. The first step is to cut the side of the straight plastic mirror frame that needs to be bent to form a straight groove with a V-shaped cross section. The second step is to It is to heat and soften the plastic frame. The third step is to bend the two sides of the softened plastic frame with a V-shaped straight groove, and bond the two grooves of the V-shaped straight groove with an adhesive. In this way, after the p...
