Description

TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a metal frame,

The present invention relates to a method of manufacturing a metal frame, and more particularly, to a method of manufacturing a metal frame by manufacturing and constructing an elastic connecting member for connecting a pair of glasses to both sides of the frame, Thereby improving its robustness and usability.

The metal frame frame according to the present invention relates to a slip-type frame frame produced by blanking a metal plate material. The description of the background of the invention will be limited to a metal frame frame produced by blanking a metal plate material.

Examples of metal frames: Patent No. 2010-0037311 'Method of manufacturing metal frames and their frames'.

A metal frame made by blanking the upper metal plate is manufactured by integrally pulling an eyeglass frame from a metal plate using a metal mold having a specific shape. More specifically, a metal plate is pulled into a metal mold to obtain a metal frame, A bridge 3 connecting the rim 2 provided with the lens mounting portions 1 and 11 on both sides and the lens mounting portions 1 and 11 and the end piece 4 formed on both side edges of the rim 2 41) at one time.

Accordingly, the metal frame according to the above-described method can be manufactured in a simple and rapid manner, which is advantageous for mass production. In particular, since the metal frame is produced through a single process, the metal frame is manufactured using a metal plate having a thickness within a range of 0.5 mm to 1 mm The cost is remarkably reduced, so there is less waste of manpower and it is more competitive. On the other hand, the weight is light and the fit is excellent.

However, the conventional conventional metal frame has many merits in manufacturing the frame, but the hinge (elastic connecting member) required when connecting the eyeglass legs from the frame has a complicated and inconvenient structure.

More specifically, in order to facilitate manufacturing as described above, a conventional metal frame is manufactured by pulling out a metal frame from a metal plate integrally formed with a lens mount, a rim, a bridge, and an end piece, The eyeglass leg connecting hinge manufactured by separate process was assembled through a piece or welding. Therefore, in the conventional glasses using the metal frame, it is troublesome and inconvenient to perform many processes for manufacturing the upper metal frame, hinge manufacturing process, and assembling the hinge with the metal frame. Particularly, The defect rate was increased, the working time was prolonged, and the appearance of the assembly site was not apparent.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the conventional problems of the prior art, and it is an object of the present invention to manufacture a metal frame by blanking, And to reduce the manufacturing time and cost with the minimum process while obtaining the convenience of the manufacture of the glasses.

The method of manufacturing a metal frame according to the present invention is characterized in that a metal plate having a thickness within a range of 0.5 mm to 1 mm is inserted into a mold apparatus to form a rim 2 in which both side lens mounting portions 1 and 11 are formed, (4) and (41) formed on both side edges of the rim (2), and a lens mounting portion (1) (1) on the center line of the end piece (4) A cut section 5 for cutting the lens mounting sections 1 and 11 to a predetermined spacing so that the lens mounting sections 1 and 11 can be opened at predetermined intervals, The hinge pieces 6 and 61 in which the connecting holes 62 are formed in the center of the hinge pieces 6 and 61 and the elastic bending bar 7 formed in a predetermined length in the direction of the hinge pieces 6 and 61, Blanking step (a) of a metallic frame material which is integrally formed at one time;

Bending of Metal Eyeglass Material The material of the metal frame obtained through step (a) is put into a bending device to bend the outer ends of both elastic bending pieces 7 at a predetermined angle to form an elastic piece 71, Step (b);

(C) folding the central portion of the both-side elastic bending piece 7 in one direction to form the elastic piece 72;

(D) bending the inner end of the elastic bending piece 7 in the direction opposite to the bending direction of the elastic piece 72 to form the elastic fixing piece 73;

The elastic piece 72 and the resilient fixing piece 73 of the elastic bending bar 7 are bent in the one direction so that the lens mounting portions 1 and 11 (B), and (c)

The upper and lower hinge pieces 6 and 61 formed by connecting the two end pieces 4 and 41 are bent at right angles inward to form a connecting space 81 to which the eyeglass legs 101 are connected, And a space forming step (f).

The metal frame frame manufactured by the above manufacturing method comprises a rim 2 on which the both side lens mounting portions 1 and 11 are formed and a bridge 3 connecting the lens mounting portions 1 and 11, 2 and 4 are formed by cutting the end pieces 4 and 41 formed at right angles to both side edges and the lens mounting portions 1 and 11 on the center line of the end piece 4 and 41 to form the lens mounting portion 1 And an elastic connecting member 8 integrally formed at an end of the end piece 41 to connect the eyeglass leg 101 to each other,

The elastic connecting member 8 includes an elastic fixing piece 73 bent in the direction of the end piece 4 and an elastic piece 72 bent outwardly from the end of the elastic fixing piece 73, An elastic piece 71 which is bent at a predetermined angle in one direction from the end of the piece 72 and a hinge piece 6 which is formed on the upper and lower sides of the end of the end piece 4 ).

The present invention relates to a method of manufacturing a metal frame by a blanking process, and at the same time, an elastic connecting member necessary for connecting glasses is integrally manufactured, thereby making it possible to manufacture the metal frame frame more quickly and conveniently, Thereby providing an advantage of improving the rigidity of the elastic connecting member where breakage occurs most frequently when using glasses while reducing manpower and manufacturing costs.

In addition, the present invention provides a simple and convenient connection operation between the metal frame and the eyeglass frame while maintaining the advantages of the metal frame, and also provides an additional effect of increasing the efficiency of the operation and the production of the frame.
