본 발명은 T.V나 모니터(Monitor)에 있어서 화상(畵像)을 비치는 브라운관의 부대품인 후레인(Frame)에 관한 것으로 특히 후레임을 제조하기 위한 각각의 공정을 한 프레스에서 동시에 이루어지도록 한 T.V 및 모니터의 브라운관용 후레임 제조방법에 관한 것이다.The present invention relates to a frame, which is an accessory of a CRT, which displays an image in a TV or a monitor, and in particular, a TV in which each process for manufacturing a frame is simultaneously performed in one press. It relates to a frame manufacturing method for a CRT of a monitor.
일반적으로 T.V나 모니터에 화상(畵 像)을 비춰주는 브라운관은 후레임에 의해 설치되는 바 후레임의 정확도, 즉 금속박판의 소재로 성형되는 후레임과 브라운관과의 공차 및 사방면에 굴곡된 부분간의 치수에 따른 공차의 정확도에 따라 브라운관에서 발하는 화상(畵 像)의 정도에 지대한 영향을 주므로 후레임의 제조에는 고도의 정밀성이 요구되는 만큼 고도의 제조기술이 요구되는 것이다.In general, a CRT that illuminates a TV or a monitor is based on the accuracy of a frame that is installed by a frame, that is, a tolerance between a frame formed by a material of a metal sheet and a CRT, and a dimension between curved portions in all directions. According to the accuracy of the tolerances have a great influence on the degree of burn out from the CRT, the manufacturing of the frame requires a high manufacturing technology as high precision is required.
그런데 문제는 금속박판으로 후레임을 제조성형하는 과정인데 보편적으로 그 작업공정은, 소정의 모양으로 성형 공작하는 드로잉(Drawing)작업, 구멍뚫기 천공 프레스 금형에 의해 소재에 목적하는 형성의 구멍을 만드는 피어싱(Piercing)작업, 목적하는 형(形)으로 만드는 포오밍(Forming)작업, 마지막으로 성형된 제품의테두리를 마무리하는 트리밍(Trimming)작업순으로 이루어지고 있다.However, the problem is the process of manufacturing and forming the frame by using a metal sheet. In general, the work process is a piercing to make a hole of a desired formation in a material by a drawing work for forming a predetermined shape, a perforation punching press mold. It consists of a piercing operation, a forming operation to produce a desired mold, and a trimming operation to finally finish the edge of a molded product.
그러나 상기와 같은 방법에 의할 경우, 각 공정이 연속성형되는 프로그래시브방법을 적용할수는 있으나, 트리밍작업시 생성되는 스크랩(scrap)만큼 재료가 손실된다는 문제점이 있었다. 특히 TV후레임과 같이 제품의 크기가 큰 경우에는 재료의 손실이 엄청나다는 문제점이 있었다.However, according to the method described above, although the progressive method of forming each process can be applied, there is a problem in that materials are lost as much as scrap generated during trimming. In particular, when the size of the product is large, such as TV frames, there is a problem that the loss of material is enormous.
상기와 같은 재료의 손실을 없애기 위해서 고안된 것으로, 전개장 전단(Blanking)작업, 드로우잉작업, 피어싱작업, 포오밍 작업을 거쳐 제품을 완성하는 공정이 행해졌다.It is designed to eliminate the loss of materials as described above, and a process of completing a product through a spreading field shearing operation, a drawing operation, a piercing operation, and a forming operation has been performed.
그러나 상기한 방법은 재료의 손실은 어느정도 줄일 수 있었으나, 제일 먼저 전단작업을 행하기 때문에 프로그래시브가 되지 못하기 때문에 각 공정을 작업한 후 다음 공정으로 별도로 운반해야 한다는 문제점이 있었다.However, the above method was able to reduce the loss of material to some extent, but because it is not progressive because the first shearing work first, there was a problem that each process must be transported separately to the next process.
즉, 종래에 개시된 방법으로는 제품성형의 자동화와 용이함을 추구하기 위하여 프로그래시브방법을 택할 경우에는 재료의 손실을 감수해야한다는 문제점이 있었고, 재료의 손실을 없애기 위해서는 프로그래시브방법을 택할 수가 없으므로 공정이 번거로와 진다는 문제점이 있었다.That is, the method disclosed in the related art has a problem in that a loss of material should be taken when the progressive method is selected in order to pursue automation and ease of product molding, and a progressive method can be selected to eliminate the loss of material. There is a problem that the process is cumbersome because there is no.
따라서 본 발명의 목적은 T.V브라운관 및 모니터용 후레임의 제조에 있어서 재료를 절감함과 동시에 프로그래시브 방법으로 공정을 진행할 수 있는 T.V브라운관 및 모니터용 후레임의 제조방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a method for manufacturing a T.V brown tube and a frame for a monitor, which can be processed in a progressive manner while reducing materials in the manufacture of the T.V brown tube and a frame for a monitor.
상기와 같은 본 발명의 목적을 달성하기 위하여 한 프레스의 펀치홀더와 다이홀더 사이에 상하 1조가 되도록 전단(Blanking), 피어싱(Piercing), 포오밍(Forming), 드로우잉(Drawing)가공 금형을 순차적으로 장착하여, 상기 전단금형에 의하여 소재를 전개장으로 전단함과 동시에 이음매와 빠이롯드홀을 형성하고, 전단공정을 거친 소재를 피어싱하고, 상기 피어싱한 소재의 주변을 내향절곡하여 포오밍하고, 상기 포오밍 된 소재의 이음매를 노칭함과 동시에 상부 드로우잉금형에 장착된 빠이롯드핀으로 소재를 고정시켜 드로우잉하여 후레임을 성형함을 특징으로 한다.In order to achieve the object of the present invention as described above, the shearing (piercing), piercing (Forming), drawing (drawing) processing mold in order to be one pair up and down between the punch holder and the die holder of a press And shearing the material to the development site by the shearing mold, forming a joint and a rod rod hole, piercing the material subjected to the shearing process, bending and forming the periphery of the pierced material inwardly, At the same time as notching the seam of the foamed material is fixed to the material by the fast rod pin mounted on the upper draw mold to draw and characterized in that forming a frame.
이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
제1도는 전단, 피어싱, 포오밍, 드로우잉가공 금형이 순차적으로 장착된 프레스에서 상부 및 하부 금형이 분리된 상태에서 가공전의 금속박판의 소재가 인입된 상태의 단면도이고, 제2도는 상부 프레스에 장착된 금형이 하향하여 상부 및 하부금형이 결합된 상태의 단면도이며, 제3도는 상기 제1도 내지 제2도에 도시된 바와 같은 프레스의 상하 동작에 따라 각각의 금형에 의하여 금속박판의 소재가 형성되는 과정을 나타낸 평면도이다.1 is a cross-sectional view of a metal sheet material before processing in a state in which the upper and lower molds are separated in a press in which shear, piercing, forming, and draw processing dies are sequentially mounted, and FIG. 2 is a top press. 3 is a cross-sectional view of the upper and lower molds combined with the mounted molds downward, and FIG. 3 shows the material of the metal thin plate by the respective molds according to the vertical movement of the press as shown in FIGS. 1 to 2. It is a top view which shows the process formed.
상기 제1도 내지 제2도에 도시된 바와 같이 펀치홀더(1)와 다이홀더(23)사이에 전단(Blanking)가공금형(2), 피어싱(Piercing)가공금형(4), 포오밍(Forming)가공금형)(6), 드로우잉(Drawing)가공금형(10)을 상하 1조를 이루도록 차례로 체결한다. 프레스의 상부 및 하부금형이 분리된 상태에서 소재를 인입하고 상부금형을 하강시키면 프레스의 힘에 의해 전단작업, 피어싱 작업, 포오밍작업, 드로우잉작업이 동시에 이루어진다.As shown in FIGS. 1 to 2, a shearing die 2, a piercing die 4, and a forming are formed between the punch holder 1 and the die holder 23. (6), draw processing (10) is fastened in order to form a pair of top and bottom. When the upper and lower molds of the press are separated and the material is introduced and the upper mold is lowered, shearing, piercing, forming, and drawing operations are simultaneously performed by the force of the press.
즉 전단(Blanking)가공금형에서는 소재가 차기 가공금형으로 순차 이동될때 그 가공금형의 위치에 정확히 도달되도록함과 동시에 정확히 안치됨을 확인시켜 고도의 빠이롯드홀을 형성하고, 동시에 브라운관의 형상으로 전단(Blanking)하되 순차 이송시 소재로 부터 브라운관의 형상으로 전단된 부분이 이탈되지 않도록 이음매를 형성한다. 상기 이음매의 형성에 의해 프로그래시브가 가능해 진다.In other words, in the blanking mold, when the material is sequentially moved to the next machining mold, the workpiece is reached exactly at the same time as the machining mold. Blanking), but form a joint so that the part sheared in the shape of the CRT from the material is not separated during sequential transfer. Formation of the seam enables progressive.
피어싱(Piercing)가공금형에서는 전단가공금형에서 전단된 브라운관 형상내에 T.V나 모니터의 화상(畵像)형태로 펀칭하여 구멍을 형성한다.In the piercing processing mold, holes are formed by punching in the shape of the T.V or monitor image in the CRT shape sheared by the shear processing mold.
포오밍(Forming)가공금형에서는 피어싱가공금형에서 화상(畵像)형태로 피어싱(Piercing)한 주변을 약간의 경사각을 이루도록 내향 절곡한다.In the forming processing mold, the piercing processing mold is bent inward so as to form a slight inclination angle around the piercing in the form of an image.
드로우잉(Drawing)가공금형에서는 포오밍가공금형에서 이송되어 온것을 브라운관과 체결할 수 있도록 성형함과 동시에 전단가공시 형성된 이음매부분을 노칭하여 완제품인 후레임을 성형하게 된다. 이때 상부금형에 장착된 빠이롯드핀에 의하여 소재가 흔들이지 않고 고정되어 정도 높은 후레임을 성형할 수 있다.In the drawing process mold, the conveyed mold is formed to be fastened with the CRT and transferred to the CRT, and at the same time, the notched joint is formed to form the finished frame. At this time, the material is not shaken by the rod rod pins mounted on the upper mold, so that a high frame can be formed.
상기와 같은 가공공정이 소재가 순차적으로 이송되면서 프레스의 한동작으로 이루어지므로써 공정마다 사람이 일일이 옮길 필요가 없어서 편리할뿐만 아니라 작업능률이 향상되어 대량생산할 수 있다.The processing process as described above is carried out in one operation of the press as the material is sequentially transported, so it is not only convenient for the person to move every process, but also improves the work efficiency and mass production.
상술한 바와 같이 본 발명은 순차 이송 연속성형하는 프로그래시브(Progressive)방법을 적용하되 전단(Blanking), 피어싱(Piercing), 포오밍(Forming), 드로우잉(Drawing)가공 공정순으로 가공을 하므로써 목적물에 제한되지 않고 폭넓게 이용될 수 있으며, 특히 정도(精度) 높은 후레임을 얻을 수 있어 T.V나 모니터에 브라운관의 설치에 따라 미치는 화상(畵像)의 정도를 높게 얻을 수 있다.As described above, the present invention applies a progressive method to sequentially transfer continuous molding, but the target object is processed in the order of shearing, piercing, forming, and drawing processing. It can be used widely without being limited to this, and in particular, a high frame can be obtained, and the degree of image affecting the installation of a CRT on a TV or a monitor can be obtained high.
