As shown in FIG. 1, when the catalyst canning is welded by the shells 1 and 2 having the same shape, there is a risk of detachment during the assembly of the cover of the catalytic converter 10. There was an additional problem.
도 2는 종래의 촉매 컨버터 조립방법을 나타낸 또 다른 실시예의 사시도로서, 도시된 바와 같이 촉매 컨버터(20)의 상/하 쉘(3,4) 형상을 다른 형상으로 용접함으로서 금형비와 부품수가 많이 드는 문제점이 있었다.Figure 2 is a perspective view of another embodiment showing a conventional catalytic converter assembly, by welding the upper and lower shell (3, 4) shape of the catalytic converter 20 to another shape, as shown in the mold cost and high component count There was a problem.
본 고안은 상기와 같은 종래기술의 제반 문제점을 해결하기 위하여 안출한 것으로 그 목적은, 촉매 컨버터 쉘의 상/하 형상을 동일한 부품형상으로 만들어 이를 반대로 조립하여 쉘의 용접시 별도의 추가 용접을 필요로 하지 않도록 함과 동시에 상기 쉘 커버의 조립성을 향상시키는 차량의 배기계용 촉매 컨버터를 제공하는데 있다.The present invention has been made in order to solve the above problems of the prior art, the purpose of which is to make the upper and lower shapes of the catalytic converter shell to the same part shape and assembling the opposite to the additional welding when welding the shell The present invention provides a catalytic converter for an exhaust system of a vehicle which does not have to be used and improves the assemblability of the shell cover.

6,7 : 쉘 8 : 볼트 체결부6,7 Shell 8: Bolt Fastening Part
30 : 촉매 컨버터30: catalytic converter
상기와 같은 목적을 달성하기 위한 본 고안의 구성은, 배기가스를 정화시키는 차량용 촉매 컨버터에 있어서 측면에 볼트 체결부를 형성하고 촉매의 상부를 둘러싸는 상기 촉매 컨버터의 상부 쉘과, 상기 상부 쉘과 동일 형상의 촉매 하부를 둘러싸는 상기 촉매 컨버터의 하부 쉘로 이루어진 것을 특징으로 한다.The structure of the present invention for achieving the above object is the same as the upper shell and the upper shell of the catalytic converter to form a bolt fastening portion on the side and surrounds the upper portion of the catalyst in a vehicle catalytic converter for purifying exhaust gas And a lower shell of the catalytic converter surrounding the lower portion of the catalyst.
이하, 첨부된 도면들을 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 고안의 촉매 컨버터를 나타낸 사시도로서, 선행기술인 도 1 및 도2를 절충, 보완하여 고안한 것이다.3 is a perspective view showing a catalytic converter of the present invention, and is designed to compromise and supplement the prior art FIGS. 1 and 2.
도 3에 도시된 바와 같이 상기 촉매 컨버터(30)의 쉘(6,7) 제작시 상/하 두 개의 쉘(6,7) 형상이 동일하여 동일한 금형으로 상/하 두 개의 쉘(6,7)을 제작할 수 있어 금형비가 줄고 동일한 쉘(6,7) 형상의 상/하부를 용접할 때 부품형상을 반대로 하여 용접함으로서 추가 용접의 필요성이 줄고, 상기 쉘(6,7)의 일 측면에 커버의 볼트 체결부(8)를 형성하여 상기 촉매 컨버터(30)의 커버 조립성이 향상되는 것이다.상기한 바와 같이 본 고안의 촉매 컨버터(30)는 종래 도 1 및 도 2를 보완하여 고안한 것으로 촉매 컨버터(30)의 쉘(6,7) 형상은 일측이 볼트에 의해 커버 조립이 가능하도록 볼트 체결부(8)가 형성되고, 동일한 금형으로 하나의 셀 형상을 만들어 용접시 부품형상을 반대로 조립하여 용접하면 용접성 및 커버의 조립성이 향상되는 것이다.As illustrated in FIG. 3, when the shells 6 and 7 of the catalytic converter 30 are manufactured, the upper and lower two shells 6 and 7 have the same shape, and thus the upper and lower two shells 6 and 7 are formed in the same mold. ), The mold cost is reduced, and when welding the upper and lower parts of the same shell (6,7) shape by welding the part shape reversely, the need for additional welding is reduced, and covers one side of the shell (6,7) The cover assembly of the catalytic converter 30 is improved by forming the bolt fastening portion 8 of the catalyst converter 30. As described above, the catalytic converter 30 of the present invention is designed to complement the conventional FIGS. 1 and 2. The shells 6 and 7 of the catalytic converter 30 have bolt fastenings 8 formed on one side thereof to allow cover assembly by bolts, and form one cell shape using the same mold to assemble the shape of the parts in reverse. Welding is to improve the weldability and cover assembly.
이상에서는 본 고안의 바람직한 실시예에 대하여 도시하고 또한 설명하였으나, 본 고안은 상기한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 본 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.In the above described and illustrated with respect to the preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment, it is common in the field to which the present invention belongs without departing from the spirit of the present invention claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.
이상에서 설명한 바와 같이 본 고안에 의하면, 촉매 컨버터 상/하 쉘의 형상을 동일하게 함으로서 용접성을 향상시키고, 금형비 및 부품수를 줄여 전체적인 가격을 절감할 수 있는 효과가 있다.As described above, according to the present invention, the same shape of the upper and lower shells of the catalytic converter can improve the weldability, and reduce the overall cost by reducing the mold cost and the number of parts.
