果を発揮させるメタルガスケットがある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to metal gaskets. A metal gasket is used for sealing between joint members, for example between the cylinder head and cylinder block of an internal combustion engine, by providing a bead on an elastic metal plate and exerting a sealing effect by the amount of elastic recovery and restoring force caused by the elastic deformation. be.
このメタルガスケットは複数枚の金属板を積層させて構
成されるのが多い。そしてこのガスケットの所定箇所に
、所定の厚みを形成させるために、副板を折り返すこと
が行われる。This metal gasket is often constructed by laminating a plurality of metal plates. Then, in order to form a predetermined thickness at a predetermined location of this gasket, the sub-plate is folded back.
従来、このように積層して、折返し工程のその後に、金
属板や相手面のツールマーク等の不整面を補償するため

部分的に不均一な厚さを有するメタルガスケットとなっ
てしまう、このため、ボルト締結時の厚さ以下に使用時
間が経過するに従い、厚さが減少し、気密が著しく低下
する不都合があった。Conventionally, after the layering and folding process, a micro-seal painting process was performed to compensate for irregular surfaces such as tool marks on the metal plate and the mating surface, so the paint could seep in between the eyebrows of the folded part and harden. This results in a metal gasket with partially uneven thickness that exceeds the specified thickness as designed, and as a result, the thickness decreases over time to less than the thickness when bolted. However, there was an inconvenience that the airtightness was significantly reduced.
本願発明のポイントは、製造工程の順序を従来の常識的
なものに代えて変更して行い、かつ、そのような工程変
更により生ずる不利益を特別の手段により解消した点に
ある。The key point of the present invention is that the order of the manufacturing steps is changed from the conventional, common sense order, and the disadvantages caused by such process changes are eliminated by special means.

次いで第4図に示す如く、折返し部12を形成する。こ
こで第2図の基板6と第4図の副板10とを積層して第
5図の積層型のメタルガスケット14を完成する。That is, as shown in FIG. 1, the micro sealing material M is applied to both sides of the elastic metal plate 2. Next, as shown in FIG. 2, beads 4 are formed at predetermined locations to obtain a substrate 6. Further, as shown in FIG. 3, a micro-sealing material M is applied to one side (or both sides may be used, if necessary) of the metal plate 8 to obtain a sub-plate 10.
Next, as shown in FIG. 4, a folded portion 12 is formed. Here, the substrate 6 of FIG. 2 and the sub-plate 10 of FIG. 4 are laminated to complete the laminated metal gasket 14 of FIG. 5.
このように製造したメタルガスケットは、ミクロシール
材の浸入が積層部分や折返し部分の間隙に浸入して滞留
していないので締結後に溶解流出する慣れがなく、ビー
ドの面圧保持を阻害せず良好なシール効果を得る。In metal gaskets manufactured in this way, the micro sealing material does not penetrate into the gaps between the laminated parts and folded parts and stay there, so there is no tendency for the micro sealing material to melt and flow out after fastening, and it does not interfere with the retention of surface pressure on the bead. Achieve a sealing effect.
なお、第6〜8図は上述実施例同様にして製造したメタ
ルガスケットの夫々他の構成を示す。Note that FIGS. 6 to 8 show other configurations of metal gaskets manufactured in the same manner as in the above-mentioned embodiments.
なお、ミクロシール材としては、例えば耐熱性及び柔軟
性を有しミクロシール効果を発揮し得る塗料等がある。Note that examples of the micro-sealing material include paints that have heat resistance and flexibility and can exhibit a micro-sealing effect.
また、ミクロシール材の被着面は、金属板の両面でも片
面でもよ(、要するにツールマーク等の不整を補償し得
るべく、被着されれば良いものである。Further, the surface to which the micro sealing material is applied may be either both sides or one side of the metal plate (in short, it is sufficient that it is applied to compensate for irregularities such as tool marks, etc.).
