이하 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 더욱 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

도 1과 도 2는 본 발명에 의한 차량용 소음기의 제조방법을 나타내는 도면으로서, 본 발명에 의해 제조되는 소음기(머플러)는 종래와 마찬가지로 판체(1a)를 절곡하여 통형상으로 형성되는 외통체(1)와, 상기 외통체(1)의 양단부를 각각 막게 되는 캡(2)과, 상기 외통체(1) 내부에 배기가스의 음파 간섭을 하기 위해 내부공간을 분리하는 다수개의 칸막이(3)와, 상기 칸막이(3)를 관통하여 배기가스 통로가 도중에 다수의 통로로 나누도록 형성한 배기파이프(4)로 이루어진다.1 and 2 illustrate a method of manufacturing a silencer for a vehicle according to the present invention. The silencer (muffler) manufactured by the present invention has an outer cylinder 1 A cap 2 for blocking both end portions of the outer cylinder 1; a plurality of dividers 3 for separating an inner space for interrupting sound waves of exhaust gas in the outer cylinder 1; And an exhaust pipe (4) formed so as to pass through the partition (3) and to divide the exhaust gas passage into a plurality of passages on the way.

이와 같이 이루어지는 소음기는 외통체(1)를 절곡기로 절곡한 뒤, 맞대기 방식 또는 겹치기 방식으로 상호 접촉하는 외통체(1)의 가장자리부를 용접하게 되는 바, 본 발명에서는 상기와 같은 외통체(1)를 절곡 형성하기 전, 준비단계에서 그 밖의 구성요소인 두 개의 캡(2)과 다수의 칸막이(3) 및 배기파이프(4)를 조립하여 준비하게 된다.In the silencer having such a structure, the outer body 1 is bent to the bending machine, and then the outer body 1 is welded to the mutually contacting body in the butt or overlapping manner. In the present invention, Two caps 2, a plurality of partitions 3, and an exhaust pipe 4 are assembled and prepared in the preparation step before the bending process.

그리고 상기 준비단계에서 준비된 캡(2)과 칸막이(3) 및 배기파이프(4)를 외통체절곡단계에서 외통체(1)로 형성할 때 각 구성요소를 함께 결합시키는 바, 상기 외통체절곡단계에서는 판체(1a)의 상부에 놓고 판체(1a)를 절곡하여 외통체(1)로 형성하게 된다.When the cap 2, the partition 3 and the exhaust pipe 4 prepared in the preparing step are formed into the outer cylinder 1 in the outer cylinder bending step, the respective components are coupled together, The plate body 1a is placed on the upper part of the plate body 1a and the outer body 1 is formed by bending the plate body 1a.

그리고 상기 외통체절곡단계에서 외통체(1)로 절곡한 직후, 용접단계를 통하여 상기 외통체절곡단계(1)에서 절곡된 외통체(1)의 가장자리부위를 용접하게 된다.Then, immediately after the outer cylinder body 1 is bent in the outer cylinder body bending step, the outer cylinder body 1 bent at the outer cylinder bending step 1 is welded through the welding step.

한편 판체(1a)로 외통체(1)로 절곡하더라도 상호 접촉하는 외통체(1)의 가장자리부를 전체적으로 용접하게 되면 용접 오차가 발생될 수 있으므로, 상기 용접단계에서는 상기 외통체절곡단계에서 절곡된 외통체(1)의 가장자리부위를 점용접 방식으로 다수의 점용접부(1b)를 형성한 뒤, 외통체(1)의 가장자리부위를 전체적으로 용접하는 것이 바람직하다.On the other hand, even if the plate body 1a is bent by the outer cylinder body 1, if the edge portion of the outer cylinder body 1 which is in contact with each other is welded as a whole, a welding error may occur. It is preferable that the edge portions of the outer cylinder 1 are welded as a whole after a plurality of spot welded portions 1b are formed by spot welding on the edge portions of the body 1.

한편 도 1과 같이 곡률반경이 작은 부위에서 용접하여 외통체를 제조하는 방식은 외통체(1)의 가장자리부위의 곡률반경이 작아서 캡과 칸막이 및 배기파이프를 놓고 외통체절곡단계로 절곡하게 되면 상호 접촉하는 외통체(1)의 가장자리부위에 들뜸 현상이 발생되어 용접단계에서 불량이 발생될 수 있어 판체(1a) 상태에서 가장자리부위를 미리 절곡하게 되는 공정이 추가될 수 있다.On the other hand, as shown in FIG. 1, in the method of manufacturing the outer cylinder by welding at a portion having a small radius of curvature, when the radius of curvature of the outer circumference of the outer cylinder 1 is small and the cap, the partition and the exhaust pipe are bent, It is possible to add a step of bending the edge portion in the state of the plate body 1a because a floating phenomenon may occur in the edge portion of the outer body 1 to be contacted and a failure may occur in the welding step.

그래서 본 발명에서는 도 2와 같이 상기 절곡단계에서 상호 밀착되는 외통체(1)의 가장자리부가 곡률반경이 큰 위치로 위치시키는 것이다.In the present invention, as shown in FIG. 2, the edge portion of the outer cylinder 1, which is in close contact with each other at the bending step, is positioned at a position having a large radius of curvature.

물론 종래와 마찬가지로 외통체(1)와 결합 접촉되는 캡(2) 등도 용접 처리하여 마무리하게 된다.Of course, as in the conventional art, the cap 2 and the like which are in contact with the outer cylinder 1 are also welded and finished.

이렇게 본 발명에서는 판체를 외통체 형상으로 절곡하는 과정에서 캡 등을 외통체에 동시에 결합할 수 있어 작업의 단순화로 인하여 소음기를 원활하게 제조할 수 있는 것이다.Thus, in the present invention, the cap or the like can be coupled to the outer body at the same time in the process of bending the plate body into the outer cylinder shape, so that the silencer can be manufactured smoothly by simplifying the operation.
