本発明は内燃機関のシリンダ部に使用するガス
ケツトで、三枚以上の金属板を重ね合わせて一体
とする積層金属ガスケツトの接合方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gasket used in the cylinder portion of an internal combustion engine, and relates to a method for joining a laminated metal gasket in which three or more metal plates are stacked and integrated.
近時金属板を重ね合わせて一体とする積層金属
ガスケツトが開発されつつあるが、複数枚の金属
板を簡単かつ容易に一体に接合する方法として
は、未だ適切な方法がない。 Recently, laminated metal gaskets in which metal plates are stacked and integrated have been developed, but there is still no suitable method for simply and easily joining a plurality of metal plates together.
本発明はこのような問題点を解決するためにな
されたもので、加工および組立てが簡単で、しか
もガスケツトの封塞性能に悪影響を与えない接合
方法を提供することを目的とするのである。 The present invention has been made to solve these problems, and it is an object of the present invention to provide a joining method that is easy to process and assemble, and does not adversely affect the sealing performance of the gasket.
以下図面について本発明の実施例を説明する。
図中Ｇはガスケツト本体、１はそのシリンダ口、
２は冷却水口、３はボルト孔、４はガスケツト本
体Ｇの一方の外層金属板、５は他方の外層金属
板、６は中層金属板である。 Embodiments of the present invention will be described below with reference to the drawings.
In the figure, G is the gasket body, 1 is its cylinder mouth,
2 is a cooling water port, 3 is a bolt hole, 4 is one outer layer metal plate of the gasket body G, 5 is the other outer layer metal plate, and 6 is an intermediate layer metal plate.
本発明においては、一方の外層金属板４の外縁
の適当な個所にそれぞれＬ型切り込み７を設ける
と共に、他方の外層金属板５の外縁の対応位置に
もＬ型切り込み８を設け、これら各切り込み７，
８によつて舌片４ａ，５ａを形成する。また中層
金属板６には前記舌片４ａ，５ａと対応する位置
に切欠９を設け、この切欠９内において前記各舌
片４ａ，５ａを第２図に示すように対向させると
共に、これら各舌片４ａ，５ａをそれぞれ対向す
る舌片側へ折り曲げて交差させた後、ガスケツト
全体をプレスして金属板４，６，５を一体に接合
する。 In the present invention, L-shaped cuts 7 are provided at appropriate locations on the outer edge of one outer metal plate 4, and L-shaped cuts 8 are also provided at corresponding positions on the outer edge of the other outer metal plate 5. 7,
8 form the tongue pieces 4a, 5a. Further, a notch 9 is provided in the middle layer metal plate 6 at a position corresponding to the tongue pieces 4a, 5a, and within this notch 9, the tongue pieces 4a, 5a are made to face each other as shown in FIG. After the pieces 4a and 5a are bent toward opposite sides and crossed, the entire gasket is pressed to join the metal plates 4, 6, and 5 together.
なお中層金属板６の枚数を複数枚にすることも
勿論可能である。 Note that it is of course possible to use a plurality of intermediate layer metal plates 6.
本発明方法は上述の通り、外層金属板にはその
外縁にＬ型切り込みを設け、中層金属板には外縁
に切欠９を設けるという簡単な加工を施すだけで
よく、組立ても二枚の外層金属板の舌片を折り曲
げ交差させて後、ガスケツト全体をプレスすれば
よいから、きわめて簡単かつ容易である。 As mentioned above, the method of the present invention requires only the simple processing of providing an L-shaped notch on the outer edge of the outer layer metal plate, and providing a notch 9 on the outer edge of the middle layer metal plate. This is extremely simple and easy, as it is sufficient to press the entire gasket after bending and crossing the tongues of the plate.
しかも本発明方法による接合部の厚さは、ガス
ケツトの他の部分の板厚の合計厚さより厚くなら
ないから、ガスケツトの封塞性能に悪影響を与え
るおそれもない。 Furthermore, since the thickness of the joint formed by the method of the present invention is not greater than the total thickness of the other parts of the gasket, there is no risk of adversely affecting the sealing performance of the gasket.
したがつて本発明は三枚以上の金属板および積
層金属ガスケツトの加工および組立てを簡単かつ
容易にすると共に、ガスケツトの封塞性能に悪響
を与えるおそれがないというすぐれた効果があ
る。 Therefore, the present invention has the excellent effect of simplifying and facilitating the processing and assembly of three or more metal plates and laminated metal gaskets, and that there is no risk of adversely affecting the sealing performance of the gaskets.
