본 고안은 자동차 배기관에 장착되는 소음기의 외통체에 관한 것으로 둘레의 용접부를 줄여 구성시킨 것이다.The present invention relates to the outer cylinder of the silencer to be mounted on the exhaust pipe of the car is configured to reduce the welded portion of the circumference.

종래의 자동차 배기관용 소음기는 그 외통이 제1도에서 보이는 바와 같이 두개의 반분체(1가)(1나)를 포개어서 마주닿는 곳을 서로 용접하여 하나의 통을 만들었기 때문에 제2도에서 보이는 바와같이 통체 양측으로 용접부가 형성되고 또 반분체로 만든 두개의 소재를 결합해야하므로 제작이 까다롭고 작업시간이 오래 소요되는 등의 불편이 있었다.In the conventional car exhaust pipe silencer, as shown in FIG. 1, since the outer cylinder overlaps two semi-powders (1 side) and 1 b, and welds to each other where they face each other, it is made in FIG. As shown, welds were formed on both sides of the cylinder, and two materials made of semi-powder had to be combined, which made the manufacturing process difficult and required a long time.

본 고안은 위와같은 종래의 결점을 시정하기 위하여 안출한 것으로 소음기 외통체의 용접부를 반감시킬수 있게 고안하여 작업이 용이하고 제품의 수명이 긴 양질의 소음기가 되게한 것인데 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention was devised to correct the above-mentioned defects, and was designed to halve the welded portion of the silencer's outer cylinder, thereby making it a high quality silencer that is easy to work with and has a long service life. As follows.

직사각형으로된 금속판 소재를 원통이되게 말아 맞닿는 곳을 용접(la)하므로서 상하로 관통되는 원통체(1) 를 만들고 이 원통체(1)의 양단을 제5도와 같은 1차축소장치(a)와 제7도와 같은 2차축소장치(b)를 차례로 거쳐 원통체의 양단이 테이퍼형으로 되는 축소부(2)(2a)를 형성하여 외통체(가)를 완성시킨 다음 그 중심부로 공지의 내통체(3)를 관통되게 끼워넣고 축소부 입구와 내통체(3)의 표면이 맞닿은 곳을 용접(4)하여서 내부에 소음재(5)를 장입시키도록한 구조이다.By rolling the rectangular metal plate material into a cylinder and welding (la), the cylindrical body 1 penetrates up and down, and both ends of the cylindrical body 1 are connected with the primary reduction device a as shown in FIG. Through the secondary reduction device (b) as shown in FIG. 7, a reduction portion (2) (2a) in which both ends of the cylindrical body are tapered is formed to complete the outer cylinder (A), and then a known inner cylinder as its center portion. (3) is inserted through and welded (4) the place where the inlet of the reduction part and the surface of the inner cylinder (3) abuts the structure so that the sound-absorbing material (5) is charged inside.

이와같이된 본 고안은 소음기의 외통체(가)를 형성할때 직사각형으로 되는 금속판 소재를 원통이 되게 맞닿는 곳을 용접(1a)하여 원통체(1)를 먼저 만든 다음 이 원통체의 양단부를 강제축소시키는 공법으로 축소가공하여 테이퍼형 축소부(2)(2a)를 형성하였기 때문에 외통체의 용접량이 반감되고 외관이 미려하게 되므로 소음기로 사용할때 배기가스등과 접촉이 되어도 쉽게 산화되지 않아 수명이 오래가는 실용적인 소음기를 만들 수 있게 되는 장점이 있고 가공이 용이하여 생산성이 높은 제품을 얻도록 되는 이점이 있다.When the outer cylinder (a) of the silencer is formed as described above, the present invention produces a cylindrical body (1) by welding (1a) a place where the metal sheet material, which is a rectangular shape, is brought into a cylindrical shape, and then forcibly reduces both ends of the cylindrical body. Since the tapered reduction part (2) (2a) is formed by the reduction process, the welding amount of the outer cylinder is reduced by half and the appearance is beautiful. Therefore, when used as a silencer, it does not easily oxidize even when it comes into contact with the exhaust gas. There is an advantage to be able to make a practical silencer, and there is an advantage to obtain a productive product with ease of processing.
