Description

촉매 컨버터 제조용 삽입장치{Insertion device for manufacturing catalytic converters}[0001] The present invention relates to an insertion device for manufacturing catalytic converters,

본 발명은 자동차의 배기 가스를 정화하는데 사용되는 촉매 컨버터 제조용 삽입장치에 관한 것으로 더욱 상세하게는 촉매 컨버터 제조시 단열재에 의해 감싸지는 촉매를 원통케이스의 내부에 밀어 삽입시키는 푸셔의 구조를 개량하여 촉매와 단열재를 원통케이스의 내부에 원활하고 효율적으로 삽입함으로써 촉매 컨버터의 품질을 향상시키고 제조를 용이하게 하고자 안출한 촉매 컨버터 제조용 삽입장치에 관한 것이다.The present invention relates to an inserting device for manufacturing a catalytic converter used for purifying exhaust gas of an automobile, and more particularly, to an inserting device for inserting a catalyst And an inserting device for manufacturing a catalytic converter, which aims to improve the quality of a catalytic converter and facilitate manufacture by inserting a heat insulating material smoothly and efficiently into a cylindrical case.

촉매 컨버터는 자동차의 배기시스템을 구성하는 하나의 구성품으로서, 불완전 연소에 의해 발생되는 탄화수소(HC)와 일산화탄소(CO) 등의 유해가스를 이산화탄소(CO2)와 수증기(H2O) 및 질소(N2)로 변환시키는 장치이다.The catalytic converter is a component of the exhaust system of an automobile. The catalytic converter converts harmful gases such as hydrocarbons (HC) and carbon monoxide (CO) generated by incomplete combustion into carbon dioxide (CO 2), water vapor (H 2 O) and nitrogen .

이러한 촉매 컨버터는 원통 케이스와, 그 내부에 단열재로 감싸여진 촉매가 삽입 설치된 구조로서 자동화 라인에서 생산되는데, 원통 케이스를 수직 또는 수평으로 위치시킨 상태에서 촉매와 이를 감싼 단열재를 원통케이스의 내부에 정밀하고 밀착되게 삽입할 수 있도록 중량을 측정하여 촉매를 감싼 단열재의 직경을 원통 케이스의 내부에 정확한 결합력으로 삽입시키기 위해 압착시킨 후 가압로드를 가진 푸셔에 의해 원통케이스의 내부에 삽입시키는 방법으로 제작된다.Such a catalytic converter is produced in an automation line, in which a cylindrical case and a catalyst enclosed therein are inserted in a heat insulating material. The catalytic converter is manufactured in an automation line. When the cylindrical case is vertically or horizontally positioned, And the diameter of the heat insulating material wrapped around the catalyst is inserted into the cylindrical case by a pusher having a pressing rod so that the diameter of the heat insulating material is inserted into the cylindrical case with an appropriate coupling force and inserted into the cylindrical case .

이와같은 촉매 컨버터 제조방법과 이에 사용되는 삽입장치는 본 출원인이 안출하여 선등록된 특허 제553257호에 개시되고 있다. A method of manufacturing such a catalytic converter and an inserting device used therein are disclosed in Japanese Patent No. 553257, which was filed by the present applicant.

상기 선등록 특허는 촉매를 감싼 단열재를 원통케이스의 내부에 삽입이 용이하도록 촉매와 단열재를 압지편에 의해 중심방향으로 압착시키는 압착장치와 압착된 촉매와 단열재를 지그를 통해 푸셔에 의해 원통케이스의 내부에 밀어 넣는 구조로서 촉매 컨버터를 자동화 라인에서 제작하는 데 매우 효율적인 장치를 제공하고 있다. In the above-mentioned prior art, a compression device for compressing a catalyst and a heat insulating material in a center direction by a pressing piece so as to facilitate insertion of a heat insulating material wrapped around the catalyst into a cylindrical case, a compressed catalyst and a heat insulating material, It has a push-in structure that provides a very efficient device for manufacturing catalytic converters in automated lines.

그러나, 상기 장치는 압착장치에 의해 압착된 촉매와 단열재를 테이퍼진 지그를 통해 원통케이스의 내부에 밀어 넣은 푸셔의 구조에 있어서 약간의 단점을 가지고 있다.However, the apparatus has some disadvantages in the structure of the pusher in which the catalyst pressed by the compression device and the heat insulator are pushed into the cylindrical case through the tapered jig.

상세하게는 촉매를 감싼 단열재를 압착하는 압착장치의 출구측에 접하는 지그는 압착장치에 접하는 입구의 직경이 반대측의 원통케이스와 접하는 출구의 직경보다 크도록 테이퍼진 내경으로 형성되어 압착장치와 지그의 내부를 왕복 운동하는 푸셔에 의해 밀려 들어가는 촉매를 감싼 단열재가 입구보다 출구측으로 테이퍼진 지그를 통과하면서 더욱 압착되어 원통케이스의 내부로 삽입된다.Specifically, the jig which is in contact with the outlet side of the compression device for pressing the heat insulating material wrapped around the catalyst is formed with a tapered inner diameter such that the diameter of the inlet contacting the compression device is larger than the diameter of the outlet contacting the cylindrical case on the opposite side, The heat insulating material wrapped by the catalyst pushed by the reciprocating pusher is further compressed and inserted into the cylindrical case while passing through the tapered jig toward the outlet side rather than the inlet.

따라서, 가압로드에 부착된 원판형의 푸셔는 지그의 출구측 내경에 대응하는 직경으로 형성되어 있는 반면에 단열재가 원통케이스의 내부에 삽입되기 전의 직경은 도 3에 도시된 바와 같이 지그의 입구측 직경과 대응하므로 결과적으로 푸셔의 직경이 삽입되기 전의 단열재의 직경보다 작아 푸셔로서 단열재와 촉매를 가압할 때 단열재의 전체 직경을 밀지 못하고 부분적으로 밀게 됨에 따라 단열재가 파열되거나 심지어는 가압과정에서 분리되는 현상이 발생되어 불량을 발생시키고 촉매 컨버터의 품질을 저하시키게 되는 문제점이 있었다.Therefore, the disc-shaped pusher attached to the pressing rod is formed to have a diameter corresponding to the inner diameter of the outlet of the jig, while the diameter before the heat insulating material is inserted into the cylindrical case is smaller than the diameter of the inlet side of the jig As a result, the diameter of the pusher is smaller than the diameter of the heat insulating material before the insertion, so that when the heat insulating material and the catalyst are pressed as the pusher, the entire diameter of the heat insulating material can not be pushed and the heat insulating material is partially ruptured, Thereby causing defects and deteriorating the quality of the catalytic converter.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로 촉매와 단열재를 왕복 운동하면서 가압하는 푸셔의 구조를 개량하여 단열재의 전체 직경을 일정하게 가압할 수 있도록 함으로써 단열재의 파열이나 분리 현상을 방지하여 촉매 컨버터의 품질을 향상시킬 수 있게 한 촉매 컨버터 제조용 삽입장치를 제공하는 데 있다.It is an object of the present invention to solve the above-mentioned problems of the prior art, and it is an object of the present invention to improve the structure of a pusher that presses a catalyst and a heat insulating material while reciprocating, thereby pressing the entire diameter of the heat insulating material constantly, And to improve the quality of the catalytic converter.

본 발명은 상기한 목적을 달성하기 위한 수단으로 일정 두께를 가진 호형상의 압지편을 일정 간격을 두고 원형으로 배치하여 압지편의 가압 작동으로 단열재를 압착하는 압착장치와; 상기 압착장치의 출구 측에 압착장치와 접하는 입구의 직경이 반대측 출구의 직경보다 크도록 테이퍼진 내경을 가진 지그와; 상기 지그의 출구측에 접하게 설치된 원통케이스와; 상기 압착장치와 지그의 내부를 왕복운동하면서 촉매를 감싼 단열재를 가압로드로서 밀어 원통케이스의 내부에 삽입시키는 푸셔;로 이루어진 촉매 컨버터 삽입장치에 있어서, 상기 푸셔는 종래와 같이 지그의 출구측 내경에 대응하는 직경으로 이루어지되 가압면의 외측에 단입홈을 형성하여 이에 신축성을 가진 가압링을 압착장치 또는 지그의 내면에 밀착되도록 환설하고 고정판으로 고정 체결하여서 됨을 특징으로 하는 촉매 컨버터 제조용 삽입장치를 제공한다.In order to achieve the above object, according to the present invention, there is provided a press apparatus comprising: a pressing device for pressing a heat insulating material by pressing operation of a pressing piece by arranging arc pressing pieces having a predetermined thickness in a circular shape at regular intervals; A jig having an inner diameter tapered at an outlet side of the compression device so that the diameter of the inlet contacting the compression device is larger than the diameter of the outlet at the opposite side; A cylindrical case provided in contact with the outlet side of the jig; And a pusher which reciprocates in the inside of the jig while pushing the heat insulating material wrapped around the catalyst as a pushing rod and inserts the pushing rod into the inside of the cylindrical case, wherein the pusher is disposed on the inner diameter of the exit side of the jig, And a presser ring having a corresponding diameter is formed on the outer side of the pressurizing surface so that the pressurizing ring having elasticity is made to be in close contact with the inner surface of the pressing device or the jig and fixed by a fixing plate. do.

또한, 본 발명의 가압링을 고정한 고정판은 볼트로서 체해결이 가능하도록 설치됨을 특징으로 한다.Further, the fixing plate fixing the presser ring of the present invention is characterized in that it is provided so as to be able to solve the problem as a bolt.

여기서, 가압링은 신축성과 내마모성을 가진 실리콘 또는 고무로 이루어짐을 특징으로 한다. Here, the pressurizing ring is characterized by being made of silicone or rubber having stretchability and abrasion resistance.

이와 같은 본 발명에 따르면, 압착장치와 지그의 내부를 왕복 운동하면서 촉매를 감싼 단열재를 가압하는 푸셔가 단열재의 전체 직경을 일정하게 가압하여 원통케이스의 내부로 삽입시키게 되므로 단열재의 파열과 분리를 방지하고 이로 인해 불량의 발생률을 감소시키고 촉매 컨버터의 품질을 향상시키는 효과가 있다.According to the present invention, the pusher for reciprocating in the compression device and the inside of the jig while pressing the heat insulating material wrapped around the catalyst presses the entire diameter of the heat insulating material constantly into the cylindrical case, thereby preventing the heat insulating material from rupturing and separating Thereby reducing the incidence of defects and improving the quality of the catalytic converter.

이하 본 발명을 첨부 도면에 의거 상세히 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 7에 도시된 바와 같이 일정 두께를 가진 호형상의 압지편(10)을 일정 간격을 두고 원형으로 배치하여 압지편(10)의 가압 작동으로 촉매(20)를 감싼 단열재(30)를 압착하는 압착장치(100)와; 상기 압착장치(100)의 출구 측에 압착장치(100)와 접하는 입구의 직경이 반대측 출구의 직경보다 크도록 테이퍼진 내경을 가진 지그(200)와; 상기 지그(200)의 출구측에 접하게 설치된 원통케이스(300)와; 상기 압착장치(100)와 지그(200)의 내부를 왕복운동하면서 촉매(20)를 감싼 단열재(30)를 가압로드(40)로서 밀어 원통케이스(300)의 내부에 삽입시키는 푸셔(400);로 이루어진 촉매 컨버터 삽입장치에 있어서, 상기 푸셔(400)는 종래와 같이 지그(200)의 출구측 내경에 대응하는 직경으로 이루어지되 가압면(50)의 외측에 단입홈(60)을 형성하여 이에 신축성을 가진 가압링(70)을 압착장치(100) 또는 지그(200)의 내면에 밀착되도록 환설하고 고정판(80)으로 고정 체결하여서 됨을 특징으로 하는 것이다.As shown in FIGS. 1 to 7, arc-shaped pressure-sensitive adhesive pieces 10 having a predetermined thickness are arranged in a circular shape at regular intervals, and the heat insulating material 30 wrapped around the catalyst 20 by the pressing operation of the pressure- (100); A jig 200 having an inner diameter tapered such that the diameter of the inlet contacting the compression device 100 is larger than the diameter of the outlet on the opposite side; A cylindrical case 300 provided in contact with the outlet side of the jig 200; A pusher 400 for pushing the heat insulating material 30 wrapped around the catalyst 20 in the compression device 100 and the jig 200 while pushing the heat insulating material 30 as the push rod 40 into the cylindrical case 300; The pusher 400 is formed to have a diameter corresponding to the inner diameter of the outlet side of the jig 200 and formed with an end groove 60 on the outer side of the pressing surface 50, The pressurizing ring 70 having elasticity is swaged so as to be in close contact with the inner surface of the compression bonding apparatus 100 or the jig 200 and fixed by a fixing plate 80.

상기 가압링(70)은 실리콘, 고무 등과 같이 신축성이 우수하고 내마모성이 우수한 재질로 이루어진다.The presser ring 70 is made of a material excellent in stretchability and excellent in abrasion resistance such as silicone and rubber.

도면 중 미설명부호 90은 가압링을 고정하는 고정판(80)을 푸셔(400)에 체결하는 볼트이다.Reference numeral 90 in the drawings denotes a bolt for fastening the fixing plate 80 for fixing the pressure ring to the pusher 400.

이와같이 된 본 발명에 있어 압착장치(100)는 촉매(20)를 감싼 단열재(30)를 원통케이스(300)의 내부에 삽입시키기 위해서 압지편(10)의 가압 작동으로 직경을 축소시켜 원통케이스(300)의 내부에 삽입이 용이하도록 하며, 지그(200)는 상기 압착장치(100)의 출구 측에 접하게 설치되어 촉매(20)와 단열재(30)를 수평으로 용이하게 이송시키면서 출구 측인 원통케이스(300) 쪽으로 가면서 테이퍼진 내경에 의해 단열재(30)를 더욱 압착하여 원통케이스(300)의 내부로 삽입이 용이하도록 하는 작용을 하게 된다. The compression bonding apparatus 100 according to the present invention reduces the diameter of the cylindrical casing 300 by pressing the pressing piece 10 in order to insert the heat insulating material 30 wrapped around the catalyst 20 into the cylindrical casing 300, And the jig 200 is disposed in contact with the outlet side of the compression bonding apparatus 100 so as to easily transport the catalyst 20 and the heat insulating material 30 horizontally, 300), the heat insulating material 30 is further compressed by the tapered inner diameter so as to facilitate insertion into the cylindrical case 300.

또한, 푸셔(400)는 가압로드(40)에 의해 단열재(30)를 뒤에서 밀어 압착장치(100)와 테이퍼진 내경의 지그(200)를 통해 수평으로 원통케이스(300)의 내부에 삽입시키는 작용을 하게 되는 것으로 본 발명의 푸셔(400)는 종래와 같이 지그(200)의 출구로 통과할 수 있는 내경에 대응하는 직경으로 이루어지되 단열재(30)와 접면되는 가압면(50)의 외측에 단입홈(60)을 형성하여 이에 신축성을 가진 가압링(70)을 압착장치(100) 또는 지그(200)의 내면에 밀착되도록 환설하고 고정판(80)으로 고정 체결하여서 되는 것이므로 푸셔(400)의 작동시 가압면(50)의 단입홈(60)에 환설된 가압링(70)이 압착장치(100) 및 지그(200)의 내면에 밀착되면서 단열재(30)의 전체 둘레와 밀착 상태로 단열재(30)를 가압하게 됨에 따라 촉매(20)와 단열재(30)는 푸셔(400) 및 가압링(70)에 빈틈없이 전체면이 밀착되어 밀려 들어가게 되는 데, 이때, 가압링(70)은 신축성이 우수한 실리콘과 같은 소재로 이루어지므로 테이퍼진 지그(200)의 내면을 통과시에 자연스럽게 수축 또는 굴신되면서 지그(200)의 내부로 진입되어 촉매(20)와 단열재(30)를 원통케이스(300)의 내부에 삽입시키게 되는 것이다. The pusher 400 has a function of pushing the heat insulating material 30 from the rear by the pressing rod 40 and inserting the heat insulating material 30 horizontally into the cylindrical case 300 through the jig 200 having the tapered inner diameter, The pusher 400 according to the present invention has a diameter corresponding to the inner diameter of the pusher 400 which can pass through the outlet of the jig 200. The pusher 400 is provided at the outer side of the pressing surface 50, Since the pressing ring 70 having the elasticity is formed to be in contact with the inner surface of the compression bonding apparatus 100 or the jig 200 and fixed by the fixing plate 80, The pressing ring 70 provided in the end groove 60 of the pressing surface 50 is in close contact with the inner surface of the compression bonding apparatus 100 and the jig 200 while being in close contact with the entire circumference of the heat insulating material 30, The catalyst 20 and the heat insulating material 30 are pressed against the pusher 400 and the pressurizing ring 70 without any gap The pressure ring 70 is made of a material such as silicone having excellent elasticity and is naturally contracted or bent when it passes through the inner surface of the tapered jig 200 to enter the inside of the jig 200 So that the catalyst 20 and the heat insulating material 30 are inserted into the cylindrical case 300.

여기서 가압링(70)은 테이퍼진 지그(200)의 내면을 자연스럽게 통과할 수 있어야 하므로 신축성과 굴신성이 우수한 소재로 이루어져야 되므로 실리콘이나 고무 재질이 바람직하고 또 잦은 왕복운동으로 마찰이 발생함에 따라 내마모성도 구비하여야 된다. Since the pressing ring 70 should be made of a material having excellent stretchability and elasticity so as to be able to pass the inner surface of the tapered jig 200 naturally, it is preferable to use silicone or rubber material, and friction occurs due to frequent reciprocating motion, .

또한, 가압링(70)은 푸셔(400)의 가압면(50)에 형성된 단입부에 고정판(80)으로 볼트에 의해 고정 체결되므로 잦은 삽입작동으로 가압링(70)이 마모되면 볼트를 풀어 고정판(80)을 분리한 후 새로운 가압링(70)으로 손쉽게 교체할 수 있다.Since the pressing ring 70 is fixed to the fixing plate 80 by bolts at the end portions of the pressing surface 50 of the pusher 400, when the pressing ring 70 is worn by the frequent insertion operation, It is possible to easily replace the presser ring 80 with a new presser ring 70 after separating it.

이와같이 본 발명은 단열재(30)보다 적은 직경을 가압링(70)에 의해 보정하여 단열재(30)의 전체면을 밀착상태로 가압하게 되므로 가압이 보다 용이할 뿐 아니라 단열재(30)의 파열과 분리를 방지하여 촉매 컨버터의 제작 과정에서 불량률을 감소시키고 촉매 컨버터의 품질을 향상시킬 수 있는 장점이 있다. As described above, according to the present invention, since the diameter of the heat insulating material 30 is reduced by the pressing ring 70 to press the entire surface of the heat insulating material 30 in an adhered state, it is easier to pressurize the heat insulating material 30, So that the defect rate can be reduced in the process of manufacturing the catalytic converter and the quality of the catalytic converter can be improved.
