A synthetic resin in which a synthetic resin such as acetic acid acetonitrile or nylon is used in a deuterated state, and the formed spectacles are removed from the frame. Further, in the above-described method for producing a stamping and cutting force, a rectangular plate-shaped plate body made of acetic acid vinegar or Saisheng Road is used, and the upper and lower slabs are pressed and pressed under the heating (four). 27 to 28, the left and right lens frame forming portions a and & are formed with a bridge forming portion b.

Also, = need: positive, so it takes a few seconds from the start of the planning of the glasses to the mass production stage, and there is a problem that cannot be immediately met. In contrast, in the manufacturing method according to the above, the one substrate can be cut according to the shape or size of the lens frame, the shape or size of the bridge, the height of the bridge, and the like. Different from the case of injection molding, it has the advantages of being able to cope with the production of many varieties and small defects. However, when the above-mentioned substrate is formed, it is formed by applying a pressure-frozen molding under the condition of heating the above-mentioned plate body, and the various parts (the shape of the inward direction in plan view) required by the glasses are applied to the plate body. Not only does it have the problem that it cannot be properly formed, but it also has the disadvantage that the shape of each part of the lens is pure. This shape-return phenomenon is because the front frame of the lens manufactured by the press and the cutting process is formed by the plasticity at the time of punching, so that it is naturally generated in addition to the change over the years and the temperature, as in the 29th. The arrow of the figure shows that when the glasses are attached, the frame hooks h and h connected to the left and right side portions g and g of the front frame f of the eye chain become expanded.

When such a phenomenon occurs, the glasses are not only allowed to ride, but also the problem of the lens of the producing area, which causes the optical performance of the lens to be reduced, and more: The problem of the frame falling off. Producing a lens Here, in order to enhance the rigidity of the front frame of the lens and to suppress such a back-up, the thickness of the plate is increased to a thickness of 6 mm.

SUMMARY OF THE INVENTION The present invention relates to the above-mentioned conventional method, and the object of the invention is to provide a front frame manufacturing substrate, which can be short-term t-stage and can produce a good variety of eyeglass front frames in small batches; The problem is to provide a substrate for the manufacture of a variety of glasses, which can be used to manufacture a front frame of glasses that is stable during a long period of time. Further, the problem is to provide a method for manufacturing a front frame of a lens for manufacturing a substrate. In order to solve the above problems, the present invention employs the following means. In other words, in the first aspect of the spectacles front frame manufacturing substrate of the present invention, the spectacles front frame forming substrate is formed by the synthetic resin, and the bridging forming portion is provided between the left and right mirror (four) frame forming portions, and if necessary, The frame forming portion of the lens is cut and defended to form a lens frame for mounting the lens, and the bridge forming portion is cut and processed as needed, thereby forming a bridge for the left and right sides. In addition, the lens is 1287650. The frame is formed in front of the frame and the shape of the front of the bridge forming portion, which is formed by the front frame of the lens to be formed, and the front of the frame (the surface opposite to the side of the face). The back of the lens frame forming portion and the rear of the bridge liU卩 are formed by the back of the frame (the side of the face) of the eyeglass frame to be formed. A second aspect of the lens front frame manufacturing substrate of the present invention, comprising: the lens frame forming portion, the convex surface having a convex spherical surface matching the lens, and the lens frame forming portion behind/there a concave spherical surface that cooperates with the concave spherical surface of the lens, and at least the front and rear inner circumferences of the flange formed by the cutting process are located on the convex spherical surface and the concave spherical surface. In the spectacles frame manufacturing substrate, the openings may be provided in a desired portion such as the center portion of the left and right lens frame forming portions without hindering the formation of the lens frame. In the above-mentioned spectacles front frame manufacturing substrate, the synthetic resin used for injection molding may be mixed with 5 to 30% of carbon as a carbon resin. In particular, the synthetic resin may be a carbon resin obtained by mixing 10 to 25% of carbon in nylon. In the method of manufacturing the eyeglass frame 4 of the first aspect of the invention, the substrate is manufactured by using the lens front frame of the first aspect to manufacture the lens front frame, and the lens frame forming portion is formed by the lens frame forming portion. By the bridge forming portion, a bridge connecting the right and left lens frames is formed. The method for manufacturing the front frame of the spectacles according to the second aspect of the present invention is the method for manufacturing the spectacles front frame according to the second aspect of the invention, wherein the lens frame forming portion is φ A lens frame is formed on the convex spherical surface and the concave spherical surface substantially in the entire front and rear inner peripheral edges, and a bridge connecting the left and right sides of the lens frame is formed by the bridge forming portion. The method for manufacturing the front frame of the lens includes a form in which the lens frame is formed in an annular cutting process, and includes a form in which the cutting process is attached only to the upper portion or the lower portion of the lens. . (Effect of the Invention) The present invention can attain the following excellent effects: (1) The present invention relates to a front frame for manufacturing a lens formed by injection molding, and a front frame for a lens for manufacturing a front frame of the lens. In the manufacturing method, the front and rear surfaces of the front and rear frames of the lens are formed by the front surface of the frame and the rear of the frame of the front frame of the lens manufactured by the cutting process, and the shape thereof is clear and fixed. Therefore, according to the present invention, it is possible to manufacture an aesthetically pleasing and natural appearance of the front frame of the glasses. 1287650 Moreover, the front frame of the lens formed by cutting the front frame manufacturing substrate of the lens is different from the front frame of the lens manufactured by the above-mentioned conventional substrate, and the front of the frame without the front frame of the lens or the state behind the frame is different. . This is because even if the fishing is connected to the left and right side portions of the front frame of the eyeglasses, the eyeglasses are deformed as the eyeglasses are opened, and the front of the frame of the eyeglass frame or the rear of the frame is deformed, and the deformation is still within the range of the elastic body. It can be restored. • The point and the front frame of the lens made by stamping and cutting are subjected to the external force caused by the above-mentioned expansion, so that the shape of each part of the front frame of the eyeglass is easily deformed, and the deformed part becomes The situation of being unrecoverable is significantly different. As apparent from the above, according to the present invention, it is possible to manufacture a resin-made spectacles front frame which is stable in such a recovery phenomenon. Therefore, the front frame of the glasses that is worn by the & φ portion can be used for a long period of time, and at the same time, the problem that the optical performance of the lens is lowered due to the inconsistency of the focus of the wearer's eye and the lens as in the conventional lens front frame does not occur. , or, does not fit, causing problems such as the lens falling off the lens frame.曰 (2) In addition, in the front frame of the above-mentioned conventional glasses, in order to suppress the above-mentioned shape-removing phenomenon as much as possible, it is necessary to increase the thickness of the plate body for punching, so as to increase the rigidity of the front frame of the lens, and to manufacture the plate body by cutting. The overall front frame of the glasses creates a feeling of being too thick, which is difficult to satisfy in the avant-garde nature of the glasses. However, according to the present invention, since there is no problem of the above-mentioned reversal phenomenon, the mirror frame can be used. The manufacturing substrate is formed to be thinner than the conventional substrate. Therefore, it is possible to manufacture a thin eyeglass front frame which is excellent in appearance. 彳φ (3) Further, the above-mentioned front glass frame manufacturing substrate according to the present invention is used in combination with the manufactured lens. Since the front frame of the front and rear frames of the frame form the substrate, the front frame of the lens can be manufactured in a stable manner, because the front frame of the front frame can be manufactured, and the front frame of the lens can be designed according to various types of design. From the above, it can be seen that by manufacturing the substrate using the front frame of the lens of the same configuration, it is possible to reduce the number of frames of the lens having a plurality of types of design configurations in a short time and at low cost. Therefore, according to the present invention, it is possible to obtain an advantage that it is easy to achieve multi-variety small-volume production that cannot be achieved by a conventional manufacturing method for manufacturing the entire front frame of the lens by injection molding. (4) In particular, as an injection molding. When a resin mixed with carbon is used, the resin can be formed into a harder lens front frame manufacturing substrate, so that the front frame of the lens can be made thinner and harder by press working, and the front of the lens can be improved. The aesthetics of the frame. In addition, the harder the hardness of the lens front frame manufacturing 1287650 2 is, the more the edge of the cutting surface can be made more prominent when the butterfly is added, so that a personalized front frame of the eyewear can be manufactured. This point is described in comparison with the above-described conventional manufacturing method. In the case of the conventional injection molding, the edge portion of the formed front frame of the lens has to be rounded with a corner. It is known that the front frame of the glasses made of acetate or celluloid made by stamping and processing is soft, so that the edge of the cut surface is clearly formed during the cutting process, and is barreled afterwards. In the end, it is still possible to have a rounded corner at the edge. In contrast, the slave resin used in the present invention can be manufactured either according to conventional injection molding or according to conventional stamping and cutting processes. The front edge of the cutting surface is clear and the front frame of the novel glasses. Moreover, by using carbon resin, the heat-resistant temperature of the resin can be improved, and a firm baking varnish can be implemented. (5) The above-mentioned left and right sides are turned into parts, and In the case where an opening is provided in the range of the cutting and the addition of the miscellaneous use of the glasses, the resin used for the injection of the yarn can be saved, and the cost of manufacturing the substrate for the front frame of the lens can be reduced. [Embodiment] [Example 1] FIG. Illustrated in Fig. 3, the spectacles front frame manufacturing substrate i of the present invention is integrally molded with synthetic resin to have substantially the same thickness, and the bridge forming portion 3 is provided between the lens frame forming portions 2 and 2 having the right and left shoe shapes. In the front view, as shown in the third _, it has a rectangular plate shape in the left and right direction. Then, the left and right lens frame forming portions 2, 2 are added as needed, and as shown in Fig. 4, the left and right annular lens frames 7, 7 for mounting the lenses 6, 6 on the inner peripheral surfaces 5, 5 are formed. Further, the bridge forming portion 3 is cut and processed as needed, and as shown in Fig. 4, a bridge 9 that connects the left and right lens frames 7 and 7 is formed, whereby the front glass frame 1 shown in Fig. 4 is manufactured. The synthetic resin may be prepared by mixing the metal powder of acetate, cellulose acetate, nylon, carbon resin, or the like, etc., and manufacturing all the synthetic resins of the front frame (1). A carbon resin is preferred. Here, the carbon resin means a resin in which carbon is mixed, and for example, a nylon resin mixed with 5 to 3 % by weight of carbon is preferred. If the carbon blending amount is smaller than 5%, it is difficult to achieve the carbon age purpose for which the lens front frame 10 is hardened, which is not desirable. Further, when the mixing is more than 3% by weight or more, the eyeglass front frame manufacturing yarn 1 becomes too hard, and there is a burden of causing lining or breakage during the above-mentioned _ processing, without paying a wish. In particular, when the mixing ratio of carbon is set to 1 〇 to 25%, the hardness of the yoke front frame manufacturing substrate 1 can be made larger, and the spectacles front frame manufacturing substrate 1 can be formed. For example, a thin plate having a thickness of 3 to 4 mm can be formed. Therefore, when the above-mentioned carbon resin is used, a thin and strong lens front frame can be manufactured, and at the same time, for example, as shown in FIG. 4, a sharp cutting face 8 which is formed by cutting to form the edge 8a can be applied, and after the barrel is rolled The front frame 1〇 also has a sharp cutting surface, so that the front frame of the glasses with high-grade feel can be manufactured. Moreover, when the mixing ratio of carbon is set to a high ratio of 23 to 24%, the heat-resistant temperature of the front frame 1 of the lens can be improved, and the temperature of the baking temperature of 170 to 180 C does not occur. Deformation, so high-strength baking varnish can be applied. As described above, the front frame of the lens manufacturing substrate i is an age-cutting worker to form left and right lens frames.
