본 발명은 동일 방향으로 밀집하게 배치된 줄무늬들을 가지게끔 돋을새김된 개량된 연자석 구조에 관한 것이다. 연자석(soft magnet)은 임의의 도구를 이용하지 않고서도 줄무늬들의 방향으로 손으로 찢어질 수 있다.The present invention relates to an improved soft magnet structure embossed to have stripes arranged densely in the same direction. Soft magnets can be torn by hand in the direction of the stripes without using any tools.

연자석은 일반적으로 산화제2철 분말과 같은 자화가능 분말과, 고무 또는 플라스틱의 혼합물로부터 만들어진 복합 박판(sheet) 또는 블록 재료이다. 그 재료는 펄스전류를 다른 자화구역들을 가진 자성 도체 디스크를 통과하게 함으로써 적어도 한 번은 자화된다. 자성도체디스크는 재료의 표면에 다른 분극들을 갖는 자극들(magetic poles)을 유도하는데 소용된다. 따라서, 유연성과 자기인력을 갖는 연자석은 자기적으로 끌어당길 수 있는 물품(이를테면 철재)을 끌어당긴다. 연자석은 장식용 자성 블록(박판), 자성 클립, 자기테이프 홀더, 또는 종이 고정용의 다른 위치고정부재들을 만드는데 사용될 수 있다. 최근, 매우 얇은 연자성 박판이 넓은 응용을 위해 개발되고 있다.Soft magnets are generally composite sheet or block materials made from a mixture of magnetizable powder, such as ferric oxide powder, and rubber or plastic. The material is magnetized at least once by passing a pulsed current through a magnetic conductor disk with other magnetization zones. Magnetic conductor disks are used to induce magnetic poles with different polarizations on the surface of the material. Thus, soft magnets having flexibility and magnetic attraction attract magnetically attractable articles (such as steel). Soft magnets can be used to make decorative magnetic blocks (thin plates), magnetic clips, magnetic tape holders, or other positioning members for fixing paper. Recently, very thin soft magnetic sheets have been developed for wide applications.

제조 절차에서, 연자석은 먼저 몰딩되고 자화된 후 제품으로 절단된다.In the manufacturing procedure, the soft magnet is first molded and magnetized and then cut into the product.

기존의 주문형 연자석은 절단에 의해 조각들로 분리된다. 박판형 연자석은 절단도구에 의해 절단되어야 한다. 특히, 연자석을 긴 길이로 절단하는 것이 필요한 경우, 정밀 측정 및 위치지정 플랫폼이 절단작업에 요구된다. 모듈화된 연자석 제조라인에서, 위의 측정 및 절단 작업들은 제조절차를 복잡하게 하고 제조비용을 증가시킨다. 그러므로, 연자석의 텍스처(texture) 및 구조를 단순화함으로써 절단 작업을 용이하게 하는 것이 출원인에 의해 시도된다.Conventional soft magnets are separated into pieces by cutting. The thin soft magnet should be cut by a cutting tool. In particular, where long lengths of soft magnets are required to be cut, precise measurement and positioning platforms are required for the cutting operation. In a modular soft magnet manufacturing line, the above measurement and cutting operations complicate the manufacturing procedure and increase the manufacturing cost. Therefore, it is attempted by the applicant to facilitate the cutting operation by simplifying the texture and structure of the soft magnet.

따라서, 본 발명의 목적은 동일 방향으로 밀집하게 배치된 줄무들을 가지게끔 돋을새김된 개량된 연자석 구조를 제공함에 있다. 이 연자석은 어떠한 도구도 사용하지 않고 줄무늬들의 방향으로 손으로 찢어질 수 있다.Accordingly, it is an object of the present invention to provide an improved soft magnet structure embossed to have the treads arranged densely in the same direction. This soft magnet can be torn by hand in the direction of the stripes without using any tools.

상기 목적을 달성하기 위한 본 발명에 따른 연자석 구조는, 연자석의 편편한 블랭크를 포함하며, 편편한 블랭크는 밀집하게 배치된 줄무늬들의 조직을 가지게 돋을새김되며, 줄무늬들은 동일 방향으로 연장하고 편편한 블랭크의 적어도 하나의 표면에 배치됨으로써, 외력 또는 전단력이 줄무늬들을 따라 연자석에 가해질 때, 연자석은 줄무늬들의 방향으로 찢어질 수 있다.Soft magnetic structure according to the present invention for achieving the above object, includes a flat blank of the soft magnet, the flat blank is embossed with a structure of stripes arranged densely, the stripes extend in the same direction and of the flat blank By being disposed on at least one surface, when an external force or shear force is applied to the soft magnet along the stripes, the soft magnet may tear in the direction of the stripes.

본 발명은 다음의 설명과 첨부 도면을 통해 가장 잘 이해될 것이다.The invention will be best understood from the following description and the annexed drawings.

도 1을 참조하면, 본 발명의 연자석의 편편한 블랭크(1)는 밀집하게 배치된 줄무늬들의 조직(2)을 가지게 돋을새김되어 있다. 줄무늬들은 등간격 또는 동일하지 않은 간격들을 가지며 동일 방향으로 연장한다. 이 실시예에서, 돋을새김된 줄무늬 조직(2)은 어느 정도 깊이를 갖는 다수의 채널들을 가진다. 이 채널들은 편편한 블랭크(1)의 적어도 하나의 표면에 형성된다.Referring to Figure 1, the flat blank 1 of the soft magnet of the present invention is embossed with a tissue 2 of stripes arranged densely. The stripes extend in the same direction with equal or unequal spacings. In this embodiment, the embossed striped tissue 2 has a number of channels with some depth. These channels are formed on at least one surface of the flat blank 1.

도 2a 및 2b는 연자석을 돋을새김하기 위한 엠보싱 기계를 보여준다. 롤러(3)의 원주면에는 동일 방향으로 연장하는 밀집하게 배치된 줄무늬형 블레이드들(31)이 형성되어 있다. 연자석의 편편한 블랭크(1)가 롤러(3)를 통과할 때, 롤러 (3)는 줄무늬 조직(2)을 가지게 편편한 블랭크를 돋을새김한다. 줄무늬 조직(2)의 배치패턴은 블레이드들(31)의 패턴에 의해 결정된다. 돋을새김된 후, 편편한 블랭크(1)에는 길이방향으로 배치된 줄무늬 조직(도 3a), 폭방향으로 배치된 줄무늬 조직(도 3b), 점선형 조직(도 3c) 등이 형성된다.2A and 2B show an embossing machine for embossing soft magnets. On the circumferential surface of the roller 3, densely arranged striped blades 31 extending in the same direction are formed. When the flat blank 1 of the soft magnet passes through the roller 3, the roller 3 embosses the flat blank with the striped structure 2. The arrangement pattern of the striped tissue 2 is determined by the pattern of the blades 31. After being embossed, the flat blank 1 is formed with striped tissue (Fig. 3a) arranged in the longitudinal direction, striped tissue (Fig. 3b) arranged in the width direction, dotted tissue (Fig. 3c) and the like.

도 4를 참조하면, 돋을새김된 줄무늬 조직(2)을 가진 연자석은 줄무늬 조직(2)의 방향에서 쉽게 손으로 찢어질 수 있다. 다르게는, 돋을새김된 줄무늬 조직(2)을 가진 연자석은 필요한 크기 및 형상에 따라 줄무늬 조직(2)의 방향으로 보조도구를 갖는 제조자에 의해 직접 찢어질 수도 있다. 그러므로, 연자석을 절단하기 전에 연자석을 미리 측정하는 것은 불필요하다. 더구나, 연자석은 어떠한 절단도구의 사용없이도 조각들로 절단될 수 있다.Referring to Figure 4, the soft magnet with embossed striped tissue 2 can be easily torn by hand in the direction of the striped tissue 2. Alternatively, soft magnets with embossed striped tissue 2 may be torn directly by the manufacturer with the aid in the direction of the striped tissue 2, depending on the size and shape desired. Therefore, it is unnecessary to measure the soft magnet in advance before cutting the soft magnet. Moreover, the soft magnet can be cut into pieces without the use of any cutting tool.

도 5는 연자석의 확대 단면도이다. 도 5는 돋을새김된 줄무늬 조직(2)이 편편한 블랭크(1) 상에 톱니구조로서 형성되어 있음을 보여준다. 돋을새김된 줄무늬 조직(2)은 이랑(ridge)부들(21), 및 인접한 이랑부들(21) 사이의 고랑부들(23)을 구비한다. 편편한 블랭크(1)의 두께는 고랑부들(23)에서 얇아서, 연자석은 외력이나 전단력에 의해 찢어질 수 있다.5 is an enlarged cross-sectional view of a soft magnet. 5 shows that the embossed striped tissue 2 is formed as a sawtooth structure on the flat blank 1. The embossed striped tissue 2 has ridges 21 and furrows 23 between adjacent ridges 21. The thickness of the flat blank 1 is thin in the furrows 23, so that the soft magnet can be torn by external force or shear force.

이상 설명한 바와 같이, 본 발명에 따르면, 동일 방향으로 밀집하게 배치된 줄무들을 가지게끔 돋을새김된 개량된 연자석 구조가 제공되어, 연자석은 어떠한 도구도 사용하지 않고 줄무늬들의 방향으로 손으로 찢어질 수 있다는 효과를 제공한다.As described above, according to the present invention, there is provided an improved soft magnetic structure embossed to have the treads arranged densely in the same direction so that the soft magnet can be torn by hand in the direction of the stripes without using any tools. Can provide the effect.
