Abstract

The method for producing pluminium temples integral with hinge portion comprises the following steps: pressforming a piece of aluminium strip into a preform of a rectangular sectioned bar having an integral protrusion for perforation of a hinge pin hole; again pressforming the preform into a desired shape of temple; cutting the protrusion in middle to form two protrusions in parallel to be perforated with the hinge pin holes; applying electrolytic polishing for the surface of the temple to be smooth and bright and to be electrocoated and colored for fitting with an end piece. The method eliminates the need of attaching a separate hinge member to the temple.

본 발명은 알미늄으로 힌지가 일체로 형성되게 제조하는 안경다리의 제조방법에 관한 것이다.The present invention relates to a method for producing a pair of spectacles legs made of aluminum so that the hinge is integrally formed.

종래에는 안경다리를 주로 백동이나 프라스틱으로 제조하므로서 안경테와 연결하는 힌지를 일체로 형성할 수가 없었다.Conventionally, the hinge is connected to the spectacle frame by integrally manufacturing the spectacle legs mainly from cupronickel or plastic.

즉 백동은 강도가 높아 힌지부분에 대한 컷팅. 천공등의 가공이 어렵고 프라스틱은 강도가 약해 힌지 부분을 일체로 형성하여도 견고성에 문제가 있어 힌지를 일체로 형성하지 못하고 별도로 제조한 다음 용접하여 붙이거나 또는 열접찹하여 제조하였다.In other words, the cupronickel has high strength and is cut to the hinge part. Difficult to process such as perforation and plastic strength is weak, even if the hinge portion is formed integrally, there is a problem in the rigidity, the hinge is not formed integrally, manufactured separately, then welded or heat bonded.

따라서 이러한 제조방법은 사람이 손으로 일일이 힌지를 정위치에 놓고 용접 또는 열접착하므로 용착공정에 시간과 인력이 많이 소모되고 용착 불량으로 인한 불량품이 발생하며 사용중 힌지가 떨어져 나갈 우려가 있고 융착부분에 용착으로 인한 흠이 생겨 외관이 미려하지 못한 등의 문제점이 있는 것이었다.Therefore, this manufacturing method is a person by hand to place the hinge in place by hand, welding or heat-sealed, so that the welding process consumes a lot of time and manpower, defective products due to poor welding, there is a fear that the hinge will fall off during use, There was a problem that the appearance was not beautiful because of a flaw caused by welding.

본 발명은 이러한 문제점을 해결하기 위하여 힌지로서의 강도가 충분하면서도 가공이 용이한 알미늄을 힌지가 일체로 형성되도록한 것으로서 이를 실시예에 따라 공정별로 상세히 설명하면 다음과 같다.In order to solve this problem, the hinge is formed integrally with sufficient strength as a hinge and easy to process aluminum, which will be described in detail according to the process according to the embodiment as follows.

[실시예]EXAMPLE

[제1공정][Step 1]

알루미늄판을 금형에 넣고 프레스로 압형하여 직사각형인 몸체(1)일측에 대체로 힌지 형상이고 보다 다소 큰 돌부(2)가 몸체(1)와 일체로 형성되도록 1차 가공품(A)을 형성한다.The aluminum plate is placed in a mold and pressed by a press to form a primary workpiece A such that a generally larger hinge portion 2 is formed integrally with the body 1 on one side of the rectangular body 1.

[제2공정][Step 2]

제1공정에서 형성된 1차 가공품(A)을 원하는 형상의 금형에 넣고 다시 프레스로 압형하여 사각형상의 몸체(1)가 원하는 형상의 안경다리(3)가 되도록 하고 돌부(2)도 형상과 크기가 힌지와 같도록 제2돌부(4)를 형성하여 2차 가공품(B)을 형성한다.The primary workpiece (A) formed in the first step is placed in a mold of a desired shape and pressed again by a press so that the rectangular body (1) becomes a pair of eyeglasses (3) of a desired shape. The second projection 4 is formed to be the same as the hinge to form a secondary workpiece (B).

[제3공정][Step 3]

2차 가공품(B)의 제2돌부(4) 중앙을 컷팅하여 좌우로 분리하고 구멍(5)을 뚫어 힌지(6)를 완성한다.The center of the second protrusion 4 of the secondary workpiece B is cut off to the left and right, and the hole 5 is drilled to complete the hinge 6.

[제4공정][Step 4]

힌지(6)가 완성된 본 발명의 안경다리(C)를 공지의 방법으로 전해 연마하여 표면이 매끄럽고 광택이 나게 한다음 전기도금하고 착색한 후 표면의 일부를 적절히 절삭하는 가공방법에 의하여 무늬를 형성하고 팁(7)을 끼우므로서 본 발명이 완성된다.The glass legs (C) of the present invention, in which the hinge 6 is completed, are polished by a known method to make the surface smooth and glossy, and then the pattern is formed by a method of appropriately cutting a part of the surface after electroplating and coloring. The invention is completed by forming and fitting the tip 7.

이와 같이 제조하는 본 발명의 안경다리는 힌지(6)를 안경다리(c)와 일체로 형성하므로서 융착공정이 생략되어서 시간과 인력이 절감되고 힌지(6)가 떨어져 나갈 우려가 없어 견고성이 높으며 융착에 의한 홈이 새기지 않으므로 외관이 미려하고 가볍고 값싼 알미늄으로 제조하므로 가격이 저렴하고 착용감이 좋은 등의 효과가 있는 것이다.The glasses legs of the present invention manufactured as described above form a hinge 6 integrally with the glasses legs c, so that the fusion process is omitted, thereby reducing time and manpower, and there is no fear that the hinge 6 may fall off. Because the grooves are not carved, the appearance is beautiful and is made of light and inexpensive aluminum, so that the effect is cheap and good to wear.

Claims

By pressing the aluminum plate so that the rectangular body 1 and the protrusion 2 are integrally formed, and pressing the aluminum plate again, the body 1 becomes an eyeglass leg 3 having a desired shape and the protrusion 2 is also shaped. And a second leg portion (4), such as the size of the hinge and then processing the second protrusion (4) to produce a hinge (6) method of manufacturing a pair of glasses.
