Description

안경테 제조방법{Makig method of spectacles}Makita method of spectacles

본 발명은 안경테를 제조하기 위한 제조공정에 관한 안경테 제조방법에 관한 것이다.The present invention relates to a spectacle frame manufacturing method related to the manufacturing process for producing the spectacle frame.

특히, 알루미늄합금판재를 단조 가압하여 조직밀도를 최대화 시키고, 외관이 매우 수려하면서도 입체감이 뛰어나며 내구성이 뛰어남과 동시에 보다 견고한 알루미늄 합금재의 안경테를 제조하기 위한 것이다.In particular, the forging and pressing of the aluminum alloy sheet material to maximize the density of the structure, the appearance is very beautiful, excellent three-dimensional, excellent durability and at the same time to produce a more rigid aluminum alloy glasses frame.

종래 알루미늄재질의 안경테를 제조하는 방법을 살펴보면 알루미늄 판재를 단조하여 밀도를 조밀하게 한뒤 안경테 형상의 프레스 금형을 이용하여 안경테를 프레스 성형하고, 이어서 가공처리후 안경다리 연결구(업계에서는 미미라 칭함 따라서 이하 "미미"라 통칭한다.)를 나사조립 하여 상기 미미에 안경다리를 연결조립하고 안경테의 중앙부에 코받침부재를 나사조정 함으로써 제조 하였는데 이는 단순히 단조, 가압된 판재에 프레스공법으로 안경테를 재단성형한 것이었다.Looking at the method of manufacturing a conventional aluminum eyeglass frame, forging an aluminum plate to densely densely and then press-molding the eyeglass frame using a spectacle-shaped press mold, and then processing the spectacle bridge connector (hereinafter referred to as mimi in the industry) "Mimi" is called.) Was manufactured by connecting and assembling the glasses legs to the Mimi and screw adjustment of the nose support member in the center of the frame, which simply cut the frame by the press method on the forged, pressurized plate Was.

특히 단조를 하여 밀도를 조밀하게 하는 이유는 재질이 알루미늄인 경우, 알루미늄 판의 구조적인 문제점 때문에 발생된다.In particular, the reason for densifying density by forging is caused by the structural problems of the aluminum plate when the material is aluminum.

즉, 알루미늄 판재 내에는 무수히 많은 공극들이 들어 있다.In other words, the aluminum plate contains a myriad of pores.

이러한 공극들은 안경테의 표면 가공시, 매끈한 코팅을 불가능하게 하고 경도 및 강도가 약하여 안경테가 쉽게 휘거나, 부러질 수 있는 소지를 가지고 있었다.These voids prevent the smooth coating during the surface processing of the spectacle frame, the hardness and the strength was weak so that the spectacle frame can be easily bent or broken.

따라서 알루미늄 재질을 이용하여 안경테를 제작할 경우에는 우선 알루미늄 판재를 가압하고, 두드려 공극을 없에고 보다 견고한 밀도를 유지시킨 후 안경테의 모양을 형성시키는 작업이 따로 이루어 졌었다.Therefore, when manufacturing the frame of the aluminum frame using the aluminum material, first press the aluminum plate, tapping to eliminate the voids and to maintain a more solid density, and then to form the shape of the eyeglass frame was made separately.

이 제작방법에 있어서 문제점은 표면가공의 시간이 많이 들어가 대량생산에 많은 무리가 따른다.The problem with this manufacturing method is that it takes a lot of time for surface processing, which leads to a lot of mass production.

즉, 프레스로 펀칭되어 모양이 형성된 안경테는 굴곡이 형성되어 있지 않고, 동일 두께로 구성되어 있어서, 완성된 안경테를 제작하기 위해서는 필요한 굴곡이 형성되도록 가공하고, 두께를 깍아 내야만 했었다.That is, the spectacle frame punched with a press was not formed with bends, but was formed with the same thickness, so that in order to produce a finished spectacle frame, the spectacle frame had to be processed, and the thickness was scraped off.

또한 이러한 제작방법의 커다란 문제점은 여기에도 있다.There is also a big problem with this manufacturing method.

안경테의 양옆 가장자리에 안경다리를 끼우기 위한 미미가 단단히 체결되어야 하는데, 이의 체결을 별도로 제작된 미미와 안경테를 용접(고주파 용접등)을 이용하여 결합시켜 왔다.Mimi should be firmly fastened to the two edges of the spectacle frame. The fastening of the spectacle frame has been combined by welding (high frequency welding, etc.).

따라서 안경제작을 위하여 또 하나의 공정이 추가되어 제작시간을 연장시키는 주요소로 작용하고 있다.Therefore, another process is added for the manufacture of glasses, which acts as a major factor to extend the production time.

본 발명은 알루미늄 합금을 이용하여 안경테를 제작하되 다수의 공정을 통하여 재질을 단조 가압하고, 쳐서 공극을 최소화한 견고한 안경테를 제작하고자 한다.The present invention is to produce a spectacle frame using an aluminum alloy, but forging and pressing the material through a number of processes, to produce a rigid spectacle frame to minimize the gap by hitting.

또한 본 발명은 안경테의 양측단에 구성된 미미부를 일체로 제작할 수 있도록 하여 제작공정도 줄이고, 보다 견고한 안경테를 제작하고자 한다.In another aspect, the present invention is to reduce the manufacturing process, to produce a more robust eyeglass frame to be able to integrally produce the mimi portion configured on both sides of the eyeglass frame.

더불어 본 발명은 다수의 가압 공정에 따라 견고하되, 얇고 모양이 깔끔한 안경테를 제작하고자 한다.In addition, the present invention is to be robust according to a number of pressing processes, to produce a thin and neat eyeglass frame.

또한 본 발명은 상기의 각각의 공정들에서 이루어지는 프레스 작업과, 금형틀에 의한 가압작업에 의해 알루미늄합금의 공극을 최소화 시키는 것에 특징이 있다.In another aspect, the present invention is characterized by minimizing the voids of the aluminum alloy by the press work and the press work made in each of the above steps.

이상에서는 본 발명의 안경테 제조공정들을 개략적으로 설명하였다.The glasses frame manufacturing process of the present invention has been described above schematically.

따라서 하기에는 도시된 도면과 함께 상세히 설명되, 상기의 개략된 제조방법을 서두로 설명을 시작한다Therefore, it will be described in detail with the drawings shown below, the description begins with the outlined manufacturing method outlined above

(1) 평판형태의 알루미늄합금판을 프레스로 가공하여 안경알 구멍을 뚫고, 미미부가 일체로 형성되도록 안경테외형을 절단하는 제 1공정(1) The first step of processing the aluminum alloy plate in the form of a plate with a press to drill a hole in the eyeglasses, and cutting the frame of the eyeglasses so that the minute portion is integrally formed.

도시된 도 1은 본 발명의 안경테 제조방법의 제 1공정을 거치는 모습을 도시한 도면이다1 is a view showing a state that goes through the first step of the manufacturing method of the spectacle frame of the present invention.

도 1(a)에서 처럼 평판으로 구성된 알루미늄합금판(30)을 프레스 작업을 통하여 안경알구멍(20)을 형성한다.As shown in FIG. 1 (a), the eyeglass holes 20 are formed by pressing the aluminum alloy plate 30 formed of a flat plate.

이렇게 형성된 알루미늄합금판(30)은 또 다시 프레스되어 도 1(b)에서 보이듯 안경테외형(10)이 형성되게 된다.The aluminum alloy plate 30 thus formed is pressed again to form the spectacle frame 10 as shown in FIG.

여기서 중요한 점은 도시된 것처럼 미미부(11)가 결합된 형태로 절개 된다는 것이다.The important point here is that the minute portion 11 is cut in a combined form as shown.

이렇게 미미부(11)가 결합되어 펀칭되어 후일 미미를 결합하는 접합공정을 줄일수 있고, 미미를 더욱 단단한 결합을 가능하게 한 고도한 제조공법인 것이다.As such, the fine portion 11 is coupled and punched to reduce the bonding process of combining the fine rice later, and it is an advanced manufacturing method that enables the more fine coupling to the fine rice.

(2) 1공정에 의해 생산된 안경테외형을 금형틀을 이용 가압하여 미미부를 90°로 절곡하고 안경의 굴곡을 형성시키며, 안경테 외부로 알루미늄합금을 삐져나오게 하여 안경테의 두께를 좁히는 제 2공정(2) The second step of narrowing the thickness of the spectacle frame by pressing the spectacle frame produced by the first step using a mold frame to bend the tail portion to 90 ° to form the bend of the spectacle and to protrude the aluminum alloy to the outside of the spectacle frame.

제 1공정에서 제작된 안경테외형(10)은 두께가 고르고 굴곡의 형성이 없기에 동일한 내주면이 형성된 금형틀에 끼워져 가압을 하게 된다.Eyeglass frame 10 produced in the first step is evenly pressurized because the thickness is uniform and there is no formation of the bend is inserted into the mold formed with the same inner peripheral surface.

이때 가압의 과정에서 미미부(11)는 90°로 절곡하게 되며, 도시된 도 2의 형태처럼 안경테외부(2)로 알루미늄합금이 밀려 삐져나가게 된다.At this time, the minute portion 11 is bent at 90 ° in the process of pressing, and the aluminum alloy is pushed out to the eyeglass frame 2 as shown in FIG. 2.

이러한 가압과정에 의해 알루미늄합금에 형성되어 있는 공극은 눌려 합금내의 밀도를 좁히며, 동일하게 유지시키게 한다.By the pressing process, the pores formed in the aluminum alloy are pressed to narrow the density in the alloy and keep them the same.

이러한 작용에 의해 후일 제조된 안경테에 표면처리인 코팅이나, 색깔, 광택을 넣을시 보다 손쉽고 깔끔한 색상을 연출할 수 있게 한다.By this action, it is possible to produce a color more easily and neatly when a coating, color, or gloss is applied to the manufactured frames.

더불어 이러한 가압공정으로 인하여 안경테의 두께는 얇아져서 무게가 적어 착용감이 우수한 안경테가 제작된다.In addition, due to this pressing process, the thickness of the spectacle frame is thin, so that the weight is less, making the spectacle frame excellent in wearing comfort.

(3) 2공정에 의해 안경테 외부로 삐져나온 알루미늄합금을 프레스로 절단하는 제 3공정(3) Third process of cutting aluminum alloy sticking out of spectacle frame by 2 process by press

도 2에 도시된 안경테는 안경테외부(2)로 삐져나온 알루미늄합금을 절단해 내야한다.The spectacle frame shown in FIG. 2 should cut off the aluminum alloy protruding into the spectacle frame 2.

그러한 과정은 프레스를 통해서 작업하게 되는데 도시된 도 3처럼 안경테외부(2)로 삐져나온 알루미늄합금을 절단해 낸다.Such a process is performed through a press to cut out the aluminum alloy protruding into the eyeglass frame 2 as shown in FIG.

중요한 점은 절단해 내는 작업중에도 금형틀내의 안경테는 가압을 당해 밀도가 조밀해지는 결과를 가져온다.It is important to note that even during the cutting operation, the spectacle frame in the mold is pressurized, resulting in denser density.

그에 따른 효과는 제 2공정에서 설명하였기에 생략하지만, 본 발명에 있어서 큰 특징은 각각의 모든 공정의 단계를 거치며 안경테는 눌려져 두께를 줄이며, 굴곡을 매끈하게 형성하고, 밀도가 조밀하게 됨은 당연한 결과이다.The effect thereof is omitted because it has been described in the second process, but the big feature in the present invention is that the eyeglass frame is pressed down to reduce the thickness, smoothly form the bend, and the density is dense through the steps of each process. .

(4) 3공정에 의해 외부가 절단된 안경테를 금형틀을 이용하여 가압하여, 안경의 굴곡을 형성시키며 안경테 내부로 알루미늄합금을 삐져나오게 하여 안경테의 두께를 좁히는 제 4공정(4) The fourth step of narrowing the thickness of the spectacle frame by pressurizing the spectacle frame cut by the third step using a mold frame to form bends of the spectacle and causing the aluminum alloy to stick out into the spectacle frame.

도 3에 도시된 외부가 절단된 안경테를 금형틀을 통하여 또다시 가압하되 이번에는 내부로 삐져나올 수 있도록 내측에 틈을 구성시켜 가압한다.The frame shown in FIG. 3 is pressed again through the mold frame, but this time pressurizes by forming a gap inside so that it can stick out to the inside.

이 공정을 거치면 도시된 도 4에서 보이듯 안경알내부(1)로 알루미늄합금이 삐져나온다.After passing through this process, the aluminum alloy squeezes out into the eyeglasses 1 as shown in FIG. 4.

물론 밀도는 더 조밀해지며 두께는 얇아지고, 경량화 됨은 당연하다.Of course, the density is denser, the thickness is thinner, and the weight is natural.

(5) 4공정에 의해 안경테 내부로 삐져나온 알루미늄합금을 프레스로 절단하는 제 5공정(5) Fifth step of cutting the aluminum alloy protruding into the spectacle frame by four step by press

4공정에서 안경알내부(1)로 삐져나온 알루미늄합금은 프레스에 의해 따져, 도 5에 도시된 것처럼 내부가 매끈해 진다.In step 4, the aluminum alloy protruding from the inside of the eyeglasses 1 is picked up by a press, and the inside thereof is smoothed as shown in FIG.

(6) 5공정을 거쳐 안경테의 굴곡과 모양이 형성된 안경테를 공지의 가공방법을 통하여 안경알 걸림홈과 안경알체결구등을 완성시키는 마무리 공정인 제 6공정들을 거치며 본 발명의 안경테는 제작된다.(6) The spectacle frame of the present invention is manufactured through the sixth steps of finishing the spectacle frame with the bend and shape of the spectacle frame through a five-step process through a known processing method.

이 공정은 안경테를 제작하고 다듬질하며 마무리하는 단계로 공지된 기존의 방법에 따라 수행된다.This process is carried out in accordance with existing methods known to make, finish and finish the spectacle frame.

즉 안경알내부(1)를 매끈하게 따내고, 안경알을 끼울 수 있도록 안경알 걸림홈부를 구성시킨다.That is, the eyeglasses inner portion (1) smoothly pulled out, and constitutes the eyeglasses engaging groove to insert the eyeglasses.

또한 도 5에 도시된 체결구(12)를 절단하고, 체결나사가 끼워지기 위한 너트부를 구성시킨다.In addition, the fastener 12 shown in FIG. 5 is cut off, and a nut part for fitting the fastening screw is configured.

이후는 색감을 내기위한 코팅이나 도금등의 공정을 위하여 연마의 단계도 거치게 된다.After that, the process of polishing for the coating or plating process to produce color.

단 본 발명의 제조방법에 의해 제작된 안경테는 이러한 작업이 거의 필요치 않을 정도로 매끈하게 제작됨이 큰 특징이다.However, the spectacle frame manufactured by the manufacturing method of the present invention is characterized in that it is manufactured smoothly so that such work is hardly necessary.

본 발명의 방법에 의하여 알루미늄합금 재질로된 안경테를 최소시간에 대량생산 가능하게 할 수 있는 유용한 발명이다.By the method of the present invention is a useful invention that can enable mass production of eyeglass frames made of aluminum alloy in a minimum time.

또한 본 가공에 따라 공극이 최소화되어 안경테의 표면이 매끈하여 피막코팅(아노다이징등)이나 칼라를 입히는등의 표면처리가 용이하다.In addition, the voids are minimized according to this process, and the surface of the spectacle frame is smooth to facilitate the surface treatment such as coating (anodizing) or color coating.

더불어 기존의 안경테 제조방법에 비하여 제작공정이 줄어 제조원가도 절감할 수 있는 산업상 이용가능한 발명이다.In addition, it is an industrially available invention that can reduce the manufacturing process as compared to the existing manufacturing method of the spectacle frame to reduce the manufacturing cost.
