본 고안은 흡기 매니폴드(INTAKE MANIFOLD)의 분기관(RUNNER)을 주관상에 고정 결합키 위한 마운팅 보스에 관한 것으로, 본 고안의 특징은 마운팅 보스의 공정 단순화로 코스트 다운 및 생산성 향상효과를 제공할 수 있게 한 것이다.The present invention relates to a mounting boss for fastening a RUNNER of an intake manifold to a main pipe. A feature of the present invention is to provide cost reduction and productivity improvement by simplifying the process of the mounting boss. It was made possible.

통상 가솔린엔진 등을 탑재한 자동차에 있어서, 엔진상으로 연료와 혼합된 에어를 분기공급하는 흡기 매니폴드는 주관상에 다수개의 분기관을 구비하여 드로틀밸브를 통하여 유입되는 연료 및 공기 혼합체를 엔진의 실린더 헤드로 공급하는 역활을 수행하여, 이와 같은 흡기 매니폴드는 주지된 바와 같이 전체가 주조, 또는 구성부재를 별도의 압출, 인발단조 등의 성형방법으로 제조하여 납땜결합으로 이루어져 왔다.In a vehicle equipped with a gasoline engine, etc., an intake manifold for branching and supplying air mixed with fuel onto an engine includes a plurality of branch pipes on a main pipe to supply fuel and air mixtures introduced through the throttle valve. By performing the role of supplying to the cylinder head, such an intake manifold, as is well known, has been made entirely by soldering by casting or forming a component by a separate extrusion or drawing forging method.

상기의 흡기 매니폴드는 실린더 헤드와 연결되는 분기관을 주관상에 안정적으로 고정결합시키기 위하여 주관에 연결되는 각 분기관이 고정될 수 있도록 마운팅 보스를 결합구성하는 바, 종래의 분기관이 삽입고정되는 접속공이 형성된 마운팅 보스는 상기 분기관의 설치위치와 각도 등에 따라 접속공의 성형위치와 형태가 복잡하게 되므로서 이를 기계가공 등으로 제작하는 데에 상당한 난점과 단점등이 따르는 것이었다.The intake manifold is configured to couple the mounting boss so that each branch pipe connected to the main pipe can be fixed in order to stably couple the branch pipe connected to the cylinder head on the main pipe, the conventional branch pipe is inserted and fixed Mounting boss is formed in the connection hole is a complicated position and shape of the connection hole in accordance with the installation position and the angle of the branch pipe is complicated, and it was accompanied by considerable difficulties and disadvantages in manufacturing it by machining.

즉, 접속공의 위치와 각도 등에 따라 마운팅 보스의 형상이 복잡하게 되어 이를 일일이 기계가공(MCT 기계가공 등)하는 데에는 상당한 기술상의 난점과 번거러움이 따르게 되어 많은 가공시간이 소요되고, 따라서 생산성의 한계 및 가격적인 면에서의 불합리성을 초래하게 되는 등 여러가지 문제점을 가지고 있었던 것이다.In other words, the shape of the mounting boss becomes complicated according to the position and angle of the connection hole, and the machining of this mounting (MCT machining, etc.) requires a lot of processing time due to considerable technical difficulties and hassles, thus limiting productivity. And there was a variety of problems, such as causing a price irrationality.

그리고, 이를 해소하기 위하여 다이캐스팅등의 성형방법으로 이를 제작토록 하였는 바, 이 역시 복잡한 형상 등에 의하여 제작상의 난점을 극복키 곤란하고 생산성은 우수한 반면 기포등과 같은 주조 결함이 발생되는 등의 복합적 문제점이 따르게 되므로서 그 실효성을 거두지 못하였던 것이다.And, in order to solve this problem, it was manufactured by molding methods such as die casting, which is also difficult to overcome manufacturing difficulties due to complicated shapes, etc. By following it did not reap its effectiveness.

본 고안에서는 상기 마운팅 보스가 가지는 제작상의 난점을 해소하여 더욱 일신된 가공성과 생산성을 갖추도록 우선 1차 준비가공(소재압출)을 거쳐 2차 완성 가공(프레스공)으로 마운팅 보스(7)의 제작이 가능하도록 극히 합리적인 가공성과 향상된 생산성을 보장하는 개량된 구조의 마운팅 보스를 제공코져 한다.In the present invention, to solve the manufacturing difficulties of the mounting boss to produce a more renewed workability and productivity, first of all through the first preliminary processing (material extrusion) through the second finished machining (press ball) to manufacture the mounting boss (7) This provides a mounting boss with an improved construction that ensures extremely reasonable machinability and improved productivity.

도1은 본 고안의 일실시예가 적용되는 흡기 매니폴드(1)의 전체 사시도를 도시한 것으로서, 흡기 매니폴드(1)는 대분하여 주관(2)과 분기관(3,3'), 실린더헤드에 연결되는 각각의 플랜지(4,5,6)로 이루어져 있으며, 본 고안의 마운팅 보스(7)는 일단이 주관(2)에 연결되고, 선단에 플랜지(4,5,6)가 연결되는 각 분기관(3,3')의 외연부에 결합되어 일체로 상호 고정토록 된다.1 shows an overall perspective view of an intake manifold 1 to which an embodiment of the present invention is applied, and the intake manifold 1 is roughly divided into a main pipe 2, a branch pipe 3, 3 ', and a cylinder head. Consists of each flange (4, 5, 6) connected to, the mounting boss (7) of the present invention is one end is connected to the main pipe (2), each of the flanges (4, 5, 6) connected to the tip It is coupled to the outer edges of the branch pipes 3, 3 'to be integrally fixed to each other.

본 고안 마운팅 보스(7)의 상단측에는 분기관(3,3')이 착설되어 브레이징용접결합되게 호형접속공(8,8')이 형성되어 있고, 상기 호형접속공(8,8')은 분기관(3,3')의 외주연이 안착고정되게 반원상으로 성형된다.Branch tops 3 and 3 'are formed at the upper end side of the present invention mounting boss 7, and arc-shaped connection holes 8 and 8' are formed to be brazed and welded, and the arc-shaped connection holes 8 and 8 'are formed. The outer periphery of the branch pipes 3, 3 'is molded in a semicircular shape to be seated and fixed.

그리고, 마운팅 보스(7)양측단 역시 분기관(3,3')이 안착고정되게 반원상의 호형접속공(8,8')이 형성되어 분기관(3,3')의 외주연을 브레이징 용접결합시킬 수 있게 된다. 상기 마운팅 보스(7)의 상 하단에는 공지된 바와 같이 체결공(10,10')을 가지는 고정돌조(9,9')가 각각 돌출성형된다.Then, both ends of the mounting boss 7 are also formed with semicircular arc-shaped connection holes 8 and 8 'so that the branch pipes 3 and 3' are seated and welded to the outer periphery of the branch pipes 3 and 3 '. Can be combined. At the upper and lower ends of the mounting boss 7, fixed protrusions 9 and 9 'having fastening holes 10 and 10' are respectively protruded.

도면 중 미설명 부호 11은 분기관(3,3')에 설치되어 흡기 매니폴드(1)의 진동을 최소화할 수 있게 하므로서 제품의 내구성을 보장키 위한 진동보강브라켓을 도시한 것이다.Reference numeral 11 in the drawing shows a vibration reinforcing bracket to ensure the durability of the product by being installed in the branch pipe (3, 3 ') to minimize the vibration of the intake manifold (1).

참고로 본 고안 마운팅 보스(7)의 제작과정을 개략적으로 살펴보면; 상기과 같이 구성된 본 고안은 도 2a와 같이 우선 분기관(3,3')이 결합되는 호형접속공(8,8')의 위치와 고정돌조(9,9')등의 성형위치를 설정하여 소재를 평면상으로 압출성형하여 적정 폭으로 절단가공한 후, 이를 프레스가공(3차원 가공)하여 완성시키게 된다.Looking at the manufacturing process of the present invention the mounting boss 7 for reference; The present invention configured as described above, as shown in Figure 2a first set the position of the arc-shaped connection hole (8, 8 ') and the fixing position (9, 9'), such as the branch pipe (3, 3 ') is coupled After extruding to planar shape and cutting to the appropriate width, it is completed by press working (three-dimensional processing).

따라서 분기관(3,3')이 각각 고정결합되도록 하는 호형접속공(8,8')이 마운팅 보스(7)상에 반원상으로 성형되어 종래와 같이 마운팅 보스(7)를 일일이 고가의 제작비가 소요되는 기계가공을 행하거나 많은 내부 결함을 수반하는 다이캐스팅 성형방법등을 채택하지 않더라도 소망하는 목적 달성이 가능하게 된다.Therefore, the arc-shaped connection holes 8 and 8 'which allow the branch pipes 3 and 3' to be fixedly coupled to each other are molded in a semicircular shape on the mounting boss 7, so that the manufacturing boss 7 can be expensively manufactured. It is possible to achieve the desired purpose even if the machining is not required or the die casting molding method involving many internal defects is not adopted.

즉, 각 분기관(3,3')이 결합되는 마운팅 보스(7)상에 호형접속공(8,8')이 반원상으로 일체적으로 성형되어 이를 간단한 프레스 가공으로 제작하는 데에 아무런 장애와 문제가 발생되지 않게 되므로서 분기관(3,3')의 설치각도와 위치등에 따라 호형접속공(8,8')이 형성되어 필연적으로 비교적 복잡한 형상을 가지게 되는 마운팅 보스(7)의 가공 안정성과 생산성 향상을 크게 제고할 수 있게 되는 것이다.That is, the arc-shaped connection holes 8 and 8 'are integrally molded in a semicircle on the mounting bosses 7 to which the branch pipes 3 and 3' are coupled, so that there is no obstacle in producing them by simple press processing. Machining of the mounting boss 7 in which arc-shaped connection holes 8 and 8 'are formed according to the installation angle and position of the branch pipes 3 and 3', which inevitably have a relatively complicated shape. This will greatly increase stability and productivity.

이상에서 상세히 살펴본 바와 같이 본 고안은 분기관(3,3')이 설치되는 호형접속공(8,8')을 반원상으로 형성하여 종래와 같이 분기관(3,3')을 삽입결합할 필요없이 호형접속공(8,8')에 안착고정시켜 브레이징용접등으로 간단히 결합구성할 수 있도록 마운팅 보스(7)의 구조를 개량, 보완하므로서 이를 비교적 손쉬운 프레스가공으로 성형제작이 가능하게 되고, 공정 단순화로 코스트 다운 및 생산성 향상효과를 기대할 수 있으며, 고정돌조(9,9')의 두께가 기존보다 증대되어 제품 전체의 강도가 증가되고 가공소재 로스(loss)의 감소(종래; 1250g→가공→250g,본 고안 ; 350g→가공→250g)효과와 함께 각 접속공(8,8')에 접속고정되는 분기관(3,3')의 상호 접합면적 증가와 구조적 보강으로 마운팅 보스의 진동보강능력이 8~10%정도 향상되는 효과를 기대할 수 있는 등 상기 언급한 바외에도 그 기대되는 효과가 극히 우수한 고안이다.As described in detail above, the present invention forms an arc-shaped connection hole (8,8 ') in which the branch pipe (3,3') is installed in a semicircle to insert and branch the branch pipe (3,3 ') as in the related art. The mounting boss 7 can be molded and formed by relatively easy press processing by fixing and mounting it on the arc-shaped connection hole (8, 8 ') so that it can be easily combined by brazing welding. Cost reduction and productivity improvement can be expected by simplifying the process, and the thickness of the fixed protrusions (9, 9 ') is increased compared to the existing ones, increasing the strength of the whole product and reducing the loss of the processed material (conventionally: 1250g → processing) → 250g, the present design: 350g → processing → 250g) with the effect of increase of mutual joint area and structural reinforcement of branch pipes (3,3 ') connected to each connection hole (8,8') and structural reinforcement The above effects can be expected to improve by about 8-10%. Besides the mentioned, the expected effect is an extremely good design.
