[발명의 상세한 설명]Detailed description of the invention
[발명의 목적][Purpose of invention]
[발명이 속하는 기술분야 및 그 분야의 종래기술][Technical Field to which the Invention belongs and Prior Art in the Field]
본 발명은 자동차, 2륜차 등의 내연기관으로부터 배출되는 배기가스정화장치의 촉매를 담지하기 위한 메탈 허니컴 담체 및 그 제조방법에 관한 것이며, 특히 단면형상이 비원형의 메탈 허니컴 담체 및 그 제조방법에 관한 것이다The present invention relates to a metal honeycomb carrier for supporting a catalyst of an exhaust gas purifying apparatus discharged from an internal combustion engine such as an automobile or a two-wheeled vehicle, and a method for manufacturing the same. About
자동차나 2륜차 등의 내연기관으로부터 배출되는 배기가스를 정화하기 위해서, 배기가스를 촉매를 담지한 허니컴 구조체로 된 코어부를 원통상의 외통내에 압입하여 메탈 허니컴 담체로 하고, 이것을 가스정화 장치내에 고정하고, 이 안에 배기가스를 통과시켜서, 가스정화를 행하고 있다. 그러나, 배기가스정화장치내의 허니컴담체를 부착하는 가스관의 형상은 반드시 진원의 형태가 아니고, 타원형, 기타의 특수형상인 것이 많고, 메탈 허니컴 담체의 단면형상은, 이것을 부착하는 가스관의 단면형상에 맞추어야 한다.In order to purify the exhaust gas discharged from an internal combustion engine such as an automobile or a two-wheeled vehicle, the core part of the honeycomb structure supporting the exhaust gas is injected into a cylindrical outer cylinder to be a metal honeycomb carrier, which is fixed in the gas purifying apparatus. In this way, exhaust gas is passed through to purify the gas. However, the shape of the gas pipe to which the honeycomb carrier is attached in the exhaust gas purifying apparatus is not necessarily a round shape, but is often an elliptical shape or other special shape, and the cross-sectional shape of the metal honeycomb carrier must be matched to the cross-sectional shape of the gas pipe to which it is attached. .
그 때문에, 종래의 비원형 메탈 허니컴 담체의 제조방법으로써 예를 들면, 원형의 허니컴 구조체를 원통형인 외통내에 압입 후에, 금형을 사용하여 난형 또는 타원형의 단면형으로 압압하는 방법이 알려져 있다(특공소 57-55886호 참조).Therefore, as a conventional method for producing a non-circular metal honeycomb carrier, for example, a method of pressing a circular honeycomb structure into a cylindrical outer cylinder and then using a mold to press into an oval or elliptical cross-sectional shape is known. 57-55886).
그러나, 이 방법은 압입후의 단면형의 긴 직경측과 짧은 직경측에서는 셀 형상으로 변형이 발생하여, 접합강도가 저하되거나, 또는 세밀도에 변화를 초래하여, 가스흐름의 흐름분포에 영향을 미친다.However, in this method, deformation occurs in the cell shape on the long diameter side and the short diameter side of the cross-sectional shape after the indentation, resulting in a decrease in the bonding strength or a change in the fineness, which affects the flow distribution of the gas flow.
또 다른 방법으로써는 비원형상의 외통과 대략 서로 흡사하고, 또 이 외통단면치수보다 일정치수를 감하여 심부를 형성하고, 이 심부의 외주에 평판과 주름판을 겹쳐서 와권상으로 감아서 코어체를 형성하고, 이것을 상기 비원형상의 외통내에 압입하는 방법이 있다(특개평 3-19684).As another method, the core portion is roughly similar to the non-circular outer cylinder, and the core is formed by subtracting a certain dimension from the outer cylinder cross-sectional dimension. Then, there is a method of press-fitting into the non-circular outer cylinder (Japanese Patent Laid-Open No. 3-19684).
그러나, 이 방법에서는 먼저 심부를 제작하고 이것을 권취축으로 하여 주름판과 평판을 겹쳐서 와권상으로 감아서 허니컴상으로 하기 때문에, 그 제조에 시간을 요하여 생산성이 좋지 않다는 결점이 있다.However, in this method, since the core part is first produced and this is the winding shaft, the corrugated plate and the flat plate are piled up and wound into a spiral wound to form a honeycomb, and thus there is a drawback in that the production takes time and the productivity is not good.
[발명이 이루고자 하는 기술적 과제][Technical problem to be achieved]
그래서, 본 발명자는 상기의 결점을 개량하고, 허니컴 구조체에 변형을 주지 않고, 생산성이 양호한 비원형 메탈 허니컴 담체를 제조하기 위해 여러가지 검토한 결과, 본 발명을 완성시킨 것으로, 본 발명의 목적은 허니컴 구조체에 변형을 주지 않고, 평판과 주름판이 규칙적으로 접촉하고, 균일한 셀구조를 나타내는 메탈 허니컴 담체의 제조방법을 제공하는데 있다.Therefore, the present inventors have completed the present invention in order to improve the above-mentioned drawbacks and to produce a non-circular metal honeycomb carrier having good productivity without deforming the honeycomb structure, and the object of the present invention is to provide a honeycomb. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing a metal honeycomb carrier in which a flat plate and a corrugated plate are in regular contact with each other and exhibit a uniform cell structure without deforming the structure.

이하, 본 발명을 도면에 의하여 구체적으로 설명하겠다.Hereinafter, the present invention will be described in detail with reference to the drawings.
도1는 본 발명의 비원형 메탈 허니컴 담체의 사시도이다. 도1에서, 평판(4)와 주름판(3)을 교호로 감아서 성형하고, 이것을 비원형인 외통(2)안에 수납하였다.1 is a perspective view of a non-circular metal honeycomb carrier of the present invention. In Fig. 1, the flat plate 4 and the corrugated plate 3 are alternately wound and molded, which is housed in a non-circular outer cylinder 2.
도2는 본 발명에 의한 제조방법을 나타낸 설명이다. 먼저, 봉상의 권취부재인 2개의 판상의 권취축(5,5)를 성형할 허니컴 담체의 형상에 합치되도록 간격 X를 두고 평행하게 배치 설비한다(도2(a)).2 is a view showing a manufacturing method according to the present invention. First, the two plate-shaped winding shafts 5 and 5, which are rod-shaped winding members, are arranged in parallel at intervals X so as to conform to the shape of the honeycomb carrier to be molded (Fig. 2 (a)).
권취축(5,5)의 각각의 축의 스플릿 부분에 평판(4) 및 주름판(5)의 단부를 삽입한다(도2(b)). 다음에 권취축(5,5)의 양자의 간격을 보지하면서 그 중심점에 설비되어 있는 권취 중심축(7)을 중심으로 하여 권취축(5,5)를 회전시킴으로써 평판 및 주름판을 적층하면서 감는다(도2(c)(d)).The end portions of the flat plate 4 and the corrugated plate 5 are inserted into the split portions of the respective shafts of the winding shafts 5 and 5 (Fig. 2 (b)). Next, while winding both the winding shafts 5 and 5, the winding shafts 5 and 5 are rotated around the winding center shaft 7 provided at the center point, and the sheets are wound while laminating flat plates and corrugated plates. (Fig. 2 (c) (d)).
본 발명에 의한 제조방법의 다른 실시태양으로써 봉상의 권취부재인 2개의 스플릿을 갖는 봉상의 권취부재(5,5)를 주름판(3) 및 평판(4)을 성형할 허니컴 담체의 형상에 합치되도록 간격 X를 두고 평행하게 배치 설비하여 고정시킨다. 이 권취부재의 둘레에 평판과 주름판을 적층하면서 감는다.According to another embodiment of the manufacturing method according to the present invention, the rod-shaped winding members 5 and 5 having two split rod-shaped winding members match the shape of the honeycomb carrier for forming the corrugated plate 3 and the flat plate 4. Arrange and fix them in parallel with a distance X if possible. Winding while laminating a flat plate and a corrugated plate around the winding member.
도3는 권취부재로써 판상체를 사용한 경우의 설명도이다. 도3에서, 이 판상부재(6,6)로 된 권취부재는 허니컴 구조체(1)의 형상에 맞춘 길이 X을 갖고, 평판 및 주름판의 측연부를 권취부재의 스플릿 부분에 삽입하여 고정시킨다(도3(a)). 다음에, 이 권취부재의 둘레를 평판(4)과 주름판(3)을 적층하며 감아서 코어체를 형성한다(도3(b)).3 is an explanatory diagram when a plate-like member is used as the winding member. In Fig. 3, the winding members made of the plate members 6 and 6 have a length X in accordance with the shape of the honeycomb structure 1, and the side edges of the flat plate and the corrugated plate are inserted and fixed to the split portion of the winding member (Fig. 3 (a)). Next, the circumference of this winding member is wound while laminating the flat plate 4 and the corrugated plate 3 to form a core body (Fig. 3 (b)).
본 발명은 상기의 방법에 의해서 평판(4)과 주름판(3)에 의해서 비원형의 허니컴 구조체(1)을 만들고, 이것을 코어부로 하고, 이 코어부와 동형상인 외통(2)안에 압입한다.The present invention makes the non-circular honeycomb structured body 1 by the flat plate 4 and the corrugated plate 3 by the above method, and makes it a core part and press-fits it into the outer cylinder 2 which is the same shape as this core part.
[발명의 효과][Effects of the Invention]
이상 설명한 바와 같이, 본 발명은 2개의 봉상 또는 판상의 부재로 되는 권취부재를 심으로 하고, 이에 평판과 주름판을 적층하며 감으므로, 얻어진 메탈 허니컴 담체는 그 중심부에서 외주부까지 일체로 구성되어 있고, 따라서, 종래 방법과 같이 메탈담체를 성형후에, 변형가공할 필요가 없으므로, 접합강도나 가스흐름의 분포에 영향을 미치지 않고, 또 심부를 특별히 성형할 필요는 없으므로 작업 공정이 적어서 경제적 효과가 있다.As described above, the present invention uses two winding or plate-like members as cores, and the flat plate and the corrugated plate are laminated and wound, so that the obtained metal honeycomb carrier is integrally formed from its center portion to its outer peripheral portion. Therefore, since the metal carrier does not need to be deformed after molding as in the conventional method, it does not affect the bonding strength or the distribution of gas flow, and there is no need to specially shape the core, so there is little work process and economic effect. .
