본 발명은 자동차의 소음기용 연결관 제조방법에 관한 것으로서, 좀더 상세히는 자동차의 소음기와 연결되는 연결관의 제조시 각각의 공정마다 프레스와 금형을 마련하여 순차적으로 공정별로 이동시켜 완료하던 작업방식을 제거하여 간편하게 생산성을 향상시킬 수 있는 것이다.The present invention relates to a method for manufacturing a connection pipe for a silencer of a vehicle, and more particularly, in the manufacture of a connection pipe connected to a silencer for a vehicle, a press and a mold are provided for each process to sequentially move a work step by step. You can easily increase productivity by removing it.

일반적으로 자동차의 소음기는 엔진에서 연소된 배기가스를 대기중으로 방출하기 전 압력과 온도 및 소음을 저감시키기 위한 것으로서, 엔진과 연결되는 배기매니폴더의 후방으로 길게 연결되는 배기관의 끝단부에 설치되는 것으로 본 발명에 사용되는 소음기의 연결관은 소음기과 배출관의 사이에 위치하여 연결하는 것으로, 도 에서 보는 바와 같이 원통형으로 직각방향으로 형성하는 것이다.In general, the silencer of a vehicle is to reduce pressure, temperature, and noise before exhausting combustion exhaust gas from the engine to the atmosphere, and is installed at the end of an exhaust pipe connected to the rear of the exhaust manifold connected to the engine. The connection pipe of the silencer used in the present invention is located between the silencer and the discharge pipe to connect, and as shown in the figure is formed in a cylindrical and at right angles.

그리고, 이러한 상기 자동차의 소음기용 연결관은 원통형으로 직각방향으로 형성하므로 그 제조방법은 판형의 소재를 일정형상으로 자르는 절단공정과; 절단된 시트소재를 연결관의 전개된 형상과 동일하게 마련하는 블랭킹공정과; 상기 전개된 형상을 원통형으로 성형하는 1,2차 드로잉공정과; 상기 원통형을 직각방향으로 형성하는 벤딩공정과; 벤딩된 외곽을 깔끔하게 마무리하는 트리밍공정을 거쳐 완성하는 것이다.In addition, since the connection pipe for the silencer of the vehicle is formed in a cylindrical shape at right angles, the manufacturing method includes a cutting process of cutting a plate-shaped material into a predetermined shape; A blanking step of providing the cut sheet material in the same manner as the developed shape of the connecting pipe; First and second drawing processes for forming the developed shape into a cylindrical shape; A bending process of forming the cylindrical shape at a right angle; This is done through a trimming process that cleans the bent exterior.

It was.

그러나, 이러한 제조방법은 각각의 공정별로 프레스와 금형을 마련하여야 하므로 많은 시설을 요구하게 되는 문제점과 또한 각각의 공정별로 작업자를 배치시켜 배치된 작업자가 수작업으로 일일이 소재를 잡고 각각의 공정에서 순차적으로 차기공정으로 이동시켜야 하는 번거러움으로 생산성이 낮아지는 원인이 되었다.However, such a manufacturing method requires presses and molds for each process, which requires a lot of facilities, and a worker who arranges the workers by each process to grasp the material manually by hand and sequentially in each process. The hassle to move to the next process caused a decrease in productivity.

본 발명은 상술한 종래의 문제점을 해결하기 위한 것으로서, 위와 같이 원통형으로 직각방향으로 형성된 자동차의 소음기용 연결관의 제조방법을 롤소재를 사용하여 연속작업을 가능케 하기 위해 상기 원통형의 본체를 반분하여 반원형으로 형성시켜 상기 반분된 경계부 일측에 끼움구를 마련하여 끼워지게 하여 별도의 용접등의 접합공정을 거쳐 완성하는 것을 발명한 것인데,The present invention is to solve the above-mentioned conventional problems, by using a roll material in the method of manufacturing a connection pipe for a silencer of a vehicle formed in a right angle in the cylindrical shape as described above by dividing the cylindrical body in half It is invented to form a semi-circular shape and to provide a fitting hole on one side of the half-divided boundary portion to be fitted and completed through a bonding process such as a separate welding,

이를 첨부된 도면과 함께 더욱 상세히 설명하면 다음과 같다.This will be described in more detail together with the accompanying drawings.

본 발명의 목적을 달성하기 위한 자동차의 소음기용 연결관의 구성으로는 도 1,2에서 보는 바와 같이 반원형이며 직각방향으로 형성하여 그 내부가 통하는 반원체(11)를 서로 대칭되게 밀착시켜 서로 밀착된 경계부의 반분면(13)을 수용하는 끼움구(12)를 일측에 형성하여 상기 각각의 끼움구(12)에 의해 반원체(11)를 고정하는 것이다.In order to achieve the object of the present invention, as shown in FIGS. 1 and 2, the connection pipe for the silencer of the automobile is formed in a semicircular shape and is formed at right angles so that the semicircular bodies 11 through which the inside communicates symmetrically are in close contact with each other. The fitting holes 12 are formed on one side to accommodate the half-sections 13 of the boundary portions, thereby fixing the semi-circles 11 by the respective fitting holes 12.
