【発明の詳細な説明】
本発明は環状の板体に環状に波形を設け、この波形は加
工硬化させて波形部分の弾性限界を高めたことを特徴と
する金属ガスケットに関するもので、その目的とすると
ころは、構成が簡単で密封性が良く、しかもくりかえし
使用ができる金属ガスケットを得るにある。Detailed Description of the Invention The present invention relates to a metal gasket characterized in that an annular plate is provided with annular corrugations, and the corrugations are work-hardened to increase the elastic limit of the corrugated portions. The purpose is to obtain a metal gasket that has a simple structure, good sealing performance, and can be used repeatedly.
本発明金属がスケットを例示図面により説明する。The metal sket of the present invention will be explained with reference to illustrative drawings.
第1図において、(1)は環状の板体でアルミニウムま
たはアルミニウム合金例えばジュラルミンなどの加工硬
化を生ずる材料で製造してある。In FIG. 1, (1) is an annular plate made of a work-hardening material such as aluminum or an aluminum alloy such as duralumin.
この板体には環状に波形(2)を設ける。この波形はプ
レスやロール等を利用して、くりかえし圧縮または延展
または叩き加工を施こして、加工硬化させて構成してあ
る。This plate is provided with annular corrugations (2). This corrugated shape is formed by repeatedly compressing, spreading, or pounding using a press or roll, and then work-hardening the material.
このように構成すると、波形部分(2)の弾性限界は高
まり、復元性が大となる。このガスケットを、密封すべ
き二面間に圧縮挟持させると、波形部分(2)は加工硬
化しているので、波形の■部は密封面に強く圧接し、高
い密封性を発揮する。With this configuration, the elastic limit of the corrugated portion (2) is increased and the restorability is increased. When this gasket is compressed and sandwiched between two surfaces to be sealed, since the corrugated portion (2) has been work-hardened, the corrugated section (■) comes into strong pressure contact with the sealing surface and exhibits high sealing performance.
また、波形部分(2)は二面間で圧縮されても、この圧
縮を解除すると、この波形部分は弾性限界が高められて
いるので復元力が大であり、ほとんど元の自由状態に復
元するので、くりかえし使用することができるのである
。In addition, even if the waveform part (2) is compressed between two surfaces, when this compression is released, the elastic limit of this waveform part is increased, so the restoring force is large, and it almost returns to its original free state. Therefore, it can be used repeatedly.
本発明金属ガスケットはその実施に当り、波形部分に前
述のようにして加工硬化を生ぜしめて後または生ぜしめ
ないで、この波形部分の片面または両面にショットピー
ニングを施こし、このショットピーニングによって波形
部分(2)に加工硬化を生ぜしめるようにして構成する
こともできる。In implementing the metal gasket of the present invention, shot peening is applied to one or both sides of the corrugated portion after or without work hardening the corrugated portion as described above, and the shot peening is performed to form the corrugated portion. (2) It is also possible to create a structure in which work hardening is caused.
なお、ショットピーニングに隙し噴射材料の粒径、材質
や粒子の形状などを適当に選ぶことにより、波形表面に
適当な■■を設けたり、■■をほとんど生ぜしめないよ
うにすることができる。In addition, by appropriately selecting the particle size, material, and particle shape of the material injected during shot peening, it is possible to create appropriate ■■ on the corrugated surface or to make it almost impossible to generate ■■. .
また、第2図に示すように環状の板体(1)における波
形部分の肉厚(t)を、波形部分以外の平板状部分の肉
厚な(T)よりも薄くし、かつ波形の頂角(B)を適当
ならしめることによりこのガスケットを、密封すべき二
面間に圧縮挟持した際、波形部分の波形は平面状にまで
伸ばされないで、波形を残したまま二面に弾性的に圧接
するようにし、密封性がよりよく、復元性もより大なる
ものとすることができる。In addition, as shown in Fig. 2, the thickness (t) of the corrugated portion of the annular plate (1) is made thinner than the thickness (T) of the flat plate portion other than the corrugated portion, and the top of the corrugation is By adjusting the corners (B) appropriately, when this gasket is compressed and sandwiched between the two surfaces to be sealed, the corrugated portion of the corrugated portion is not stretched out to a flat surface, but the corrugated portion remains and the two surfaces are elastic. This allows for better sealing and greater restorability.
