Glasses processing method in which metal sheet is wrapped on the surface of rubber sheet material

Abstract

A glasses machining method for covering the surface of an acetate sheet with a metal sheet comprises the following steps that 1, the 4.0 acetate sheet is subjected to fine carving and rough shape cutting; 2, the acetate sheet is baked to be soft, and a steel needle is beaten into the acetate sheet; 3, grooves in two sides are machined through fine carving, and a metal accessory is clamped on an acetate blank; 4, an upper mold and a lower mold are mounted on a 15-ton hydraulic machine; 5, metal is clamped in the finely-carved grooves of the acetate blank and sleeved with a medium-pressure mold to be placed in an oven for heating; 6, the acetate sheet is placed in the sealed oven for heating and baking; 7, after the acetate sheet is completely softened, the acetate sheet and the medium-pressure mold are sleeved with a lower pressure mold in an oil press together, and the pressure is adjusted to be 1 ton for direct pressing; 8, the acetate sheet is taken out, and redundant acetate and metal on the surface are rubbed down through a waterproof abrasive paper machine; 9, after the procedure of pressing the metal with the acetate blank is completed, the other glass procedures are carried out according to traditional method machining subsequent procedures, and finished glasses are made.

Description

technical field [0001] The invention belongs to the technical field of spectacles manufacturing, and in particular relates to a spectacles processing method in which a metal sheet is wrapped on the surface of a rubber sheet material. Background technique [0002] At present, in the production process of glasses, the traditional technology cannot directly wrap the metal on the surface of the rubber sheet, and can only be reinforced and locked on the surface of the rubber sheet with screws. For example, the Chinese patent with the authorized announcement number CN2684224Y discloses a standard glasses The spectacle frame is composed of a spectacle frame and a spectacle lens. Bolts are arranged on the spectacle frame. A grooved metal sheet sliding along the bolt left and right is arranged on the outer frame of the spectacle lens. The grooved metal sheet is fixed on the bolt by a nut. The installation of metal sheets connected by threads is complicated, and they are easy to fall ...

Problems solved by technology

[0002] At present, in the production process of glasses, the traditional technology cannot directly wrap the metal on the surface of the rubber sheet, and can only be reinforced and locked on the surface of the rubber sheet with screws. For example, the Chinese patent with the authorized announcement number CN2684224Y discloses a standard glasses It is composed of a spectacle frame and a spectacle lens. There are bolts on the spectacle frame, and a grooved metal sheet that slides left and right along the bolt is arranged on the outer frame of the spectacle lens. The grooved metal sheet is fixed on the bolt by a nut.

The installation of the metal sheet connected by thread is complicated, it is easy to fall off after a long time, and it is impossible to wrap the metal fittings on the inside and outside
