본 발명은 비디오 카세트 테이프에 있어 테이프의 진행을 안내하는 테이프가이드(TAPE GUIDE)를 제조하는 방법에 관한 것이다.The present invention relates to a method of manufacturing a tape guide (TAPE GUIDE) for guiding the progress of a tape in a video cassette tape.
구체적으로 롤판재를 원통형으로 조관시켜 판재의 양단부를 용접한 다음 열처리와 인발 및 휨교정과 절단 과정을 거치게 하고 이를 다시 제품양측면 가공과정과 양측면 연마 및 1,2차 표면연마과정과 초음파 세척과정을 연속적으로 거치게 하여 중앙에 중공(中空)이 형성되는 테이프가이드가 양산되게 하는 제조방법을 제공하려는 것이다.Specifically, the roll plate is made into a cylindrical tube and welded to both ends of the plate, followed by heat treatment, drawing, bending correction, and cutting.Then, the product is processed on both sides of the product, on both sides, and on the first and second surface polishing and ultrasonic cleaning processes. It is intended to provide a manufacturing method to mass-produce the tape guide is formed in the center (hollow) by passing through continuously.
일반적으로 비디오 카세트 테이프의 테이프가이드는 제6도에 도시된 바와같이 테이프(t)의 진행을 안내하는 역활을 수행하는 것으로 테이프가 손상되는 것을 방지하기 위하여 설정된 사이즈(ø23.6×20ℓmm)로서 표면의 조도만 매그럽게 가공되며 그 역할을 수행하는데 전혀 지장이 초래되지 않음은 이미 알려진 사실이다.In general, the tape guide of a video cassette tape has a size (? 23.6 x 20 lmm) set to prevent the tape from being damaged by performing a role of guiding the progress of the tape t as shown in FIG. It is a known fact that only roughness of is processed smoothly and does not cause any problem in performing its role.
따라서 종래의 테이프가이드(g)는 봉(棒)재를 절단하고 이를 표면 연마처리하여 제조되어 왔으나, 이같이 소재를 봉재를 사용할 경우 무게가 무거워 비디오 카세트 테이프의 중량을 가중시키는 요인이 되었을 뿐만 아니라 설정된 치수로서 표면 연마만 매끄럽게 되며 역활을 수행하는데 전혀 지장이 초래되지 않음에도 불구하고 제품의 내부에까지 재료가 들어찬 봉재를 사용하였기 때문에 재료손실에 따른 원가 상승이 초래되므로서 양산제품에 해당되는 테리프가이드의 대내외적인 경재력이 상실되는 문제점을 수반하고 있었다.Therefore, the conventional tape guide (g) has been manufactured by cutting the rod material and polishing the surface thereof. However, when the rod material is used in this way, the weight is heavy, and it is not only a factor that increases the weight of the video cassette tape. Only the surface grinding as a dimension is smooth, and even though it does not cause any problem in performing the role, since the bar is filled with the material up to the inside of the product, the cost increases due to the loss of material, which leads to the product type. It was accompanied by the loss of the internal and external economic power of the guide.
본 발명의 주된 목적은 테이프가이드의 무게 경량화의 재료절감을 도모할 수 있는 비디오 카세트 테이프용 테이프가이드의 제조방법을 제공하는데 있으며, 다른 목적은 제품을 연속적을 제조가능하게 하는 테이프가이드의 제조방법을 제공하는데 있다.The main object of the present invention is to provide a method of manufacturing a tape guide for a video cassette tape that can reduce the weight and weight of the tape guide material, and another object of the present invention is to provide a method of manufacturing a tape guide that can continuously manufacture a product To provide.
본 발명에의해 제조된 테이프가이드는 중앙에 중공이 형성된 원통형의 형상을 갖추게 되므로 중공에 해당되는 재료절감과 무게 경량화를 도모케 된다.Tape guide manufactured by the present invention is to have a cylindrical shape with a hollow formed in the center, thereby reducing the weight and weight of the material corresponding to the hollow.
본 발명에서 가장 특징적인 것은 소재를 롤판재를 사용하여 제조되게 하므로서 연속적으로 제품을 양산시킬 수 있다는 점에 있는 것으로, 이하 첨부된 실시도면에 의거하여 각 공정별로 보다 상세히 설명하면 다음과 같다.The most distinctive feature of the present invention is that the material can be continuously produced by allowing the material to be manufactured using a roll plate material, which will be described below in more detail by each process based on the accompanying drawings.
본 발명의 소재는 제2도에 도시된 바와같이 판재(1)가 두루마리상으로 권취된 롤판재(1)가 사용되며 이 롤판재(1)는 권취기에 장치되어 서서히 풀리도록 되어 있다.As the material of the present invention, as shown in FIG. 2, a roll plate 1 on which a plate 1 is wound in a roll shape is used, and the roll plate 1 is installed in a winder so as to be gradually released.
롤판재(1)의 롤(W)은 완성된 제품(1')의 외직경(D)이 전개되는 길이를 가지게 된다.The roll W of the roll board material 1 has the length which the outer diameter D of the completed product 1 'unfolds.
즉, W=πD로서,That is, W = πD,
W=롤판재(1)의 폭W = width of roll plate (1)
π: 3.14π: 3.14
D : 제품(1)의 외직경이다.D: It is the outer diameter of the product (1).
따라서 서서히 풀림되는 롤판재(1)는 조관기로 이동되어 조관공정을 거치게 된다. 이 공정은 제3도에 도시된 바와같이 롤판재(1)의 폭(W)이 화살표 도시와 같이 소성 변형되어 원형이 되도록 하는 공정이고 롤판재(1)는 본 공정을 거치게 되므로서 길다란 원통형체로 연속 조관되어 나오게 되는 것으로, 이 공정에서 롤판재(1) 중앙에 중공(2)이 형성되게 된다.Therefore, the roll plate material 1 that is slowly loosened is moved to the tube tube to go through the tube process. As shown in FIG. 3, the width W of the roll plate 1 is plastically deformed to be circular as shown by the arrow, and the roll plate 1 is a long cylindrical body through this process. In this step, the hollow tube 2 is formed at the center of the roll plate 1.
조관공정을 거친 원통형의 롤판재(1) (제품)은 용접공정에서 제품(1)의 양단부(1a)(1a')가 자동용접장치에 의해 연속적으로 용착되고, 이와같이 열용착되므로서 용접부위의 경도와 제품(1)자체의 경도가 일정치 않은 것을 균일하게 하기 위해 곧이어 열처리노에 장입된 후 연차적으로 분해노에 장입되는 열처리공정에 들어간다.The cylindrical roll plate material 1 (product) which has undergone the tube forming process is continuously welded at both ends 1a, 1a 'of the product 1 by an automatic welding device in the welding process, and thus heat welded. In order to make the hardness and the hardness of the product (1) itself uneven, it immediately enters the heat treatment furnace and then enters the heat treatment process in which it is charged into the decomposition furnace annually.
열처리공정의 열처리노는 제품(1)을 전체적으로 가열되게 하고 분해 노에서는 열처리노에서 가열된 제품(1)을 서냉되게 함에 따라 재질특성상 게품(1) 조직이 균일하고 안정된 조직을 갖게 되고 균일된 경도를 갖게 된다.The heat treatment furnace of the heat treatment process heats the product (1) as a whole, and in the decomposition furnace, as the product (1) heated in the heat treatment furnace is cooled slowly, the structure of the article (1) has a uniform and stable structure due to the characteristics of the material. Will have
다음 공정인 인발공정은 제품(1)을 초경다이스를 통과되게 하여 어느 일부위라도 일그러짐이 없는 정원형 상태의 제룸(1)이 되게 하는 공정이고 교정 및 절단공정은 제4도에 도시한 바와같이 다수의 교정로울러(3) 사이로 제품(1)이 통과되게 하여 길이방향으로의 직선이 휘어집이 없이 일직상태가 되게 하는 휨 교정공정과 직선교정된 제품(1)을 설정된 길이가 되도록 바이트나 컷팅기(4)로서 연속적으로 절단하는 절단공정이다.The drawing process, which is the next process, causes the product 1 to pass through a cemented carbide die so that it becomes a garden-shaped gerum 1 without any distortion on the part, and the calibration and cutting process is shown in FIG. Bite or cutting machine that allows the product (1) to pass through a plurality of calibration rollers (3) so that the straight line in the longitudinal direction is in a straight state without bending, and the straightened product (1) to the set length (4) is a cutting process to cut continuously.
이러한 공정들을 거치게 되면 제품(1)은 날개상의 제품(1')이 되고 이 제품(1')은 바이트등과 같은 초경 절삭공구에 의해 양측면(1b) (1b')이 면치기(모따기)되는 제품 양측면 가공공정이 실시되고 이 공정에서 제품(1')의 기장치수가 확정된다.Through these processes, the product 1 becomes a wing-shaped product 1 'and the product 1' is faced (chamfered) on both sides 1b and 1b 'by a carbide cutting tool such as a bite. Both sides of the product are processed, and the number of devices of the product 1 'is determined in this process.
이어서 양측면 연마공정이 실시되는데 제품(1')의 양측면(1b) (1b')연마는 바렐연마기를 사용하는 것이 바람직하고, 이때 이바리와 같은 날카로운 부분이 연마되어 없어지게 된다.Subsequently, both side polishing processes are carried out. For both side surfaces 1b and 1b 'of the product 1', it is preferable to use a barrel polishing machine, and at this time, a sharp part such as a barley is polished and removed.
표면 연마공정은 1,2차로 나누어 실시된다. 이는 연삭숫돌차와 조정숫돌차 사이에 제품(1')을 개재시켜 연마케 하는 센터리스(centerless)연산방법에 의해 1차 표면 연삭공정이 실시되고, 제품(1')의 표면에 비교적 가는 연마적(숫돌)을 가벼운 압력으로 누르고 이것에 진폭이 작은 진동을 주면서 제품(1')을 회전시키므로서 표면을 정밀하게 다듬는 슈우퍼피니싱(superfinishomg)연삭방법에 의해 2차 표면 연삭공정이 실시되므로서 매끄러운 표면을 얻게 된다.The surface polishing process is carried out in two parts. The primary surface grinding process is performed by a centerless calculation method in which the product 1 'is interposed between the grinding wheel and the adjustment wheel, and the surface is relatively thin on the surface of the product 1'. The secondary surface grinding process is performed by the superfinishomg grinding method, which precisely polishes the surface by rotating the product (1 ') while pressing the red stone with light pressure and giving a small vibration to it. You get a smooth surface.
상기한 연마공정시에 제품(1')표면에 묻은 이물질은 초음파 세척기에 의한 초음파세척공정을 거치게 하여 깨끗이 세척되게 하고 최종적으로는 검사를 하게 되는데 이때는 육안검사 내지는 샘플검사를 실시하므로서 완성된 제품(1')을 얻게된다.The foreign matter on the surface of the product (1 ') during the polishing process is subjected to an ultrasonic cleaning process by an ultrasonic cleaner to be cleaned and finally inspected. In this case, the finished product (by visual inspection or sample inspection) 1 ').
본 발명 제조방법에 의해 얻어진 제품(1')은 매끄러운 표면을 얻을 수 있기 때문에 본연의 역활을 수행하는데 전혀 지장이 초래되지 않을 뿐만 아니라 중앙에 중공(2)이 형성되기 때문에 그 중공(2)에 해당하는 만큼의 재료가 절감되고 무게 경감을 이룰 수 있다.Since the product 1 'obtained by the production method of the present invention can obtain a smooth surface, not only does it cause any problem in performing its original role, but also the hollow 2 is formed in the center thereof. As much material can be saved and weight can be reduced.
그러므로 본 발명에 다르면 제품 재료절감에 따른 원가절감을 도모할 수 있으므로 대내외적인 가격 경쟁력을 향상시킬 수 있는 효과와 더불어 비디오 카세트 테이프(V)의 중량 경감에 일익을 담당할 수 있는 효과를 제공하게 된다.Therefore, according to the present invention, it is possible to reduce the cost according to the product material savings to provide an effect that can play a role in reducing the weight of the video cassette tape (V) as well as the effect of improving the internal and external price competitiveness.
특히 본 발명의 제조방법은 소재를 롤판재(1)를 사용하여 제조하므로서 연속적 제조가 가능하게 되어 양산체제의 자동생산라인을 구축할 수 있는 특징이 있다.In particular, the manufacturing method of the present invention is characterized by being able to continuously manufacture by manufacturing the material using the roll plate material (1) to build an automatic production line of the mass production system.
