Abstract
Description
본 발명은 실린더헤드의 밀봉을 위해 사용되는 메탈형 가스켓에 관한 것이다.The present invention relates to a metal gasket used for sealing of a cylinder head.
실린더헤드 가스켓은 실린더블록과 실린더헤드와의 접촉면에 끼워져 그 면을 밀착시켜 기밀을 유지함과 동시에 냉각수와 엔진오일의 누출을 방지하는 것으로 내압성, 내열성 및 적당한 압축성 등이 요구되며, 실린더헤드 가스켓은 압축재를 연강판으로 둘러싼 복합형과 연강판만으로 형성된 메탈형으로 나뉘어진다.The cylinder head gasket is inserted into the contact surface between the cylinder block and the cylinder head to keep the airtight by keeping the airtight, and to prevent leakage of coolant and engine oil. It is divided into a composite type surrounding the ash steel plate and a metal shape formed only of the mild steel plate.
메탈형 가스켓은 금속의 탄성을 이용하여 시일하는 것으로서 압축복원성이 좋고 내열, 내압성이 우수한 특징을 갖는다.Metal-type gasket is a seal using the elasticity of the metal, it has a feature of excellent compression recovery and heat resistance and pressure resistance.
메탈형 가스켓(10)은 도 2에 도시하는 것과같이 비드부(11)(12)를 갖는 복수매의 강판(13)(14)을 적층한 후 그의 테두리(즉, 보어의 원형을 따른 테두리)를 강판으로 된 스톱퍼(15)로서 U자형으로 돌려붙여 형성하고 있다.The metal gasket 10 is laminated with a plurality of sheets of steel plates 13 and 14 having bead portions 11 and 12, as shown in FIG. Is formed by turning in a U shape as a stopper 15 made of steel sheet.
상기와 같은 구조의 메탈형 가스켓(10)은 실린더 보어 테두리를 따라 배치되는 스톱퍼(15)가 1차 시일링 역활을 하며, 2차로 비드부(11)(12)에서 시일링을 하며, 스톱퍼(15)에 의해 압축력 작용에 의한 비드부(11)(12)의 주저앉음을 방지하여 내구성을 향상시키고 있다.In the metal gasket 10 having the structure as described above, the stopper 15 disposed along the edge of the cylinder bore serves as the first sealing, and the second sealing is performed in the bead portions 11 and 12, and the stopper ( 15) prevents the seating of the bead portions 11 and 12 due to the compressive force action to improve durability.
그러나 상기한 종래 구조에 의한 메탈형 가스켓에 의하면 다음과 같은 문제점이 있는 것으로 지적되고 있다.However, the metal type gasket according to the conventional structure has been pointed out to have the following problems.
1차 시일링이 이루어지는 스톱퍼(15)에 의해 결속되어 있는 강판(13)(14)들이 적측상태로 단순 밀착하여 묶여져 있어 진동을 흡수하는 추종성이 부족하므로 약간의 상대방(실린더헤드 또는 실린더블록) 물체의 거동에 의해 시일성을 상실하고 2차 시일부위인 비드부(11)(12)에서 시일하여야 되나 비드부(11)(12)가 눌려져 영구변형되는 경우 가스가 누설되고 내구성이 저하되는 문제점이 있다.The steel sheets 13 and 14, which are bound by the stopper 15, in which the primary sealing is made, are simply tightly tied together in a stacking state, and thus have a lack of followability to absorb vibrations. It is necessary to seal in the bead parts 11 and 12, which are secondary seal parts, but the bead parts 11 and 12 are deformed due to the behavior of the gas. have.
이에 본 발명은 상기한 문제점을 감안하여 제안한 것으로서 그의 목적으로 되는 것은Accordingly, the present invention has been proposed in view of the above problems, and the object thereof is that
진동에 추종하여 시일성의 안정적 확보가 가능하며 비드부의 주저앉음을 방지하여 내구성을 향상시킬 수 있는 구조의 메탈형 가스켓을 제공하는데 있다.It is to provide a metal-type gasket structure of the structure that can secure the stability of the seal in accordance with the vibration and to improve the durability by preventing the bent portion sitting.

이하 본 발명의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 의한 메탈형 가스켓을 나타내는 도면이다.1 is a view showing a metal gasket according to the present invention.
본 발명의 메탈형 가스켓(1)은 3장의 금속판재로 형성되는데 상·하부판(2)(3)은 각각 상하로 돌출하도록 가공된 비드부(4)(5)가 형성되어 있다.The metal gasket 1 of the present invention is formed of three metal plate members, and the upper and lower plates 2 and 3 are formed with bead portions 4 and 5 which are processed to protrude upward and downward, respectively.
그리고 상·하부판(2)(3) 사이에는 중간판(6)이 개재되어 있으며, 상·하부판(2)(3)의 수평단부(2')(3')에는 작게 굴곡진 주름으로 형성된 파형부(7)가 형성되어 있고, 그 3장의 금속판(2)(3)(6)이 적층되는 형태로 실린더블록과 실린더헤드 사이에 삽입된다.The intermediate plate 6 is interposed between the upper and lower plates 2 and 3, and the corrugated wave is formed in the horizontal ends 2 'and 3' of the upper and lower plates 2 and 3 with small curved wrinkles. The part 7 is formed and inserted between the cylinder block and the cylinder head in such a manner that the three metal plates 2, 3, 6 are stacked.
상기 상·하부판(2)(3)은 풀비드 타입의 종래 플레이트와 동일하고 고탄성, 예를들면 SUS 301 재질로 형성되고, 그 사이에 개재되는 중간판(6)은 탄성력이 약한 재질, 예를들면 SUS 304 재질을 사용하며 파형부(7)를 프레스 가공에 의해 형성한다.The upper and lower plates (2) and (3) are the same as the full-bead type conventional plates and are formed of high elasticity, for example, SUS 301, and the intermediate plate 6 interposed therebetween is made of a material having a weak elastic force, for example For example, SUS 304 material is used, and the corrugation part 7 is formed by press working.
프레스 용량은 시일하고자 하는 압보다 3∼5배 정도 높은 압으로 높은비드를 눌러붙여 낮은 높이의 복잡한 파형부를 형성하게 되며, 프레스의 압축에 의해 불필요한 비드의 소성 변형을 방지하게 된다.The press capacity presses high beads at a pressure about 3 to 5 times higher than the pressure to be sealed to form a complicated corrugated portion having a low height, thereby preventing unnecessary plastic deformation of the press by compression of the press.
이와같은 본 발명은 1차적 시일링은 프레스 가공한 중간판(6)의 파형부(7)에서 이루어지며, 중간판(6)의 재질이 저탄성이나 파형부(7)만은 프레스 가공에 의해 높은 탄성을 가지며, 스톱퍼 역활을 수행하여 비드부(4)(5)의 주저앉음을 방지한다.In the present invention as described above, the primary sealing is made in the corrugated portion 7 of the press plated intermediate plate 6, and the material of the intermediate plate 6 is low in elasticity, but only the corrugated portion 7 is formed by pressing. It has elasticity and performs a stopper role, thereby preventing the bead portion 4 and 5 from sitting down.
그리고 파형부(7)에 의해 상대편의 작은 변동에 추종할 수 있어 2차 시일을 위한 비드부(4)(5)의 손상을 방지하게 된다.The corrugation portion 7 can follow the small fluctuation of the other side, thereby preventing damage to the bead portions 4 and 5 for the secondary seal.
이에따라 상대방 물체의 움직임이 클때는 파형부(7)에서는 감당이 곤란하므로 이때에는 고탄성이며 추종성이 높은 상·하부판(2)(3)의 비드부(4)(5)를 통해 2차적 시일을 하게 된다.Accordingly, when the movement of the other object is large, it is difficult to handle in the corrugated portion 7, and at this time, secondary sealing is performed through the bead portions 4 and 5 of the upper and lower plates 2 and 3 having high elasticity and high followability. do.
이상과 같은 본 발명은 큰 비드부가 있는 상·하부판 사이에 작은 비드부로형성되는 파형부를 가지는 중간판이 적층되어 있어, 상대방의 작은 움직임에는 파형부가 추종하여 1차적으로 시일하며, 상대방의 큰 움직임에는 상·하부판이 추종하여 시일하므로써 종래와 달리 비드부의 주저앉음이 방지되어 내구성이 증대되며, 중간판이 상·하부판의 비드부에 대하여 스톱퍼로서 기능하여 별도의 스톱퍼 부재가 생략되는 효과가 있다.In the present invention as described above, the intermediate plate having a corrugated portion formed by a small bead portion is stacked between the upper and lower plates with a large bead portion, and the small portion of the opponent is followed by the corrugated portion and is primarily sealed. Unlike the conventional case, the lower plate is sealed to prevent the bent portion from sitting down, thereby increasing durability, and the intermediate plate functions as a stopper with respect to the bead portion of the upper and lower plates, thereby eliminating a separate stopper member.
