【発明の詳細な説明】 本発明はガスケツトの製造方法に関する。[Detailed description of the invention] The present invention relates to a method of manufacturing a gasket.

たアスベストの圧縮性を利用して耐熱性と同時に
緊定固着することにより密封効果を図つたもので
ある。 Conventionally, gaskets 1, especially for automobile engine heads, have mainly been made of asbestos, copper,
It is possible to cover the cylinder hole with a thin plate such as aluminum or iron, or to fit a ring-shaped high pressure prevention ring (grommet) 2 made of a thin steel plate into the cylinder hole corresponding part of the gasket, especially in the cylinder hole connection part. It is considered normal. Other methods have also been adopted, such as holding the asbestos in the middle with an aluminum plate and integrating it, but in any case, these methods utilize the compressibility of flocculent asbestos to achieve heat resistance. At the same time, the sealing effect is achieved by firmly fixing the parts.
然るに、近時アスベストの使用はアスベスト自

の使用の状況によつては、アスベスト微粉塵の大
気中への浮遊は重大な公害源として指摘されるに
至つた。 However, in recent years, the use of asbestos has been pointed out as a serious source of silicosis and pollution due to the inhalation of fine asbestos dust into the human body. Depending on the situation, the suspension of fine asbestos dust in the atmosphere has come to be pointed out as a serious source of pollution.
一方精密性の観点から、アスベストの圧縮性は
ボルト等による締付けによつて、エンジンヘツド
部とシリンダー部との関係的な精度に狂いを生
じ、特にロータリーエンジン側面用のガスケツト
としては、その不精確性なるが故に実用的でな
く、性能面にも影響を与える結果となつた。 On the other hand, from the viewpoint of precision, the compressibility of asbestos causes imbalances in the relative accuracy between the engine head and cylinder when tightened with bolts, etc., and this inaccuracy is particularly important for gaskets on the side surfaces of rotary engines. Due to its nature, it is not practical and has an impact on performance.
更に、該ガスケツトのシリンダー孔接続部の薄

における不一致性のため、ボルトでの締付力に対
しても完全なる気密効果が得られなかつた。 Furthermore, the thin metal ring (grommet) 2 at the cylinder hole connection part of the gasket is fitted to reinforce the asbestos against pressure fluctuations such as explosions, suction, and exhaust within the cylinder.
Due to the inconsistency in contact between the smooth metal surface of the ring and the roughness of the finished surface of the cylinder head, a complete airtight effect could not be obtained even against the tightening force of the bolt. .

ンダー外への油漏れ等の原因となつた。 However, with the recent shift to an overhead cam system for engines, the gasket 1 is integrally attached to the bolt on the same plane that includes the drive hole 3 and the cylinder hole 4 in order to drive the chain by interlocking the cam in the engine head. When tightening the cam chain, a large amount of oil that lubricates the cam chain may be sucked into the cylinder hole through the small gap in the reinforcing ring of the gasket, and high-pressure gas may leak, causing oil to leak outside the cylinder. It became.

体としたガスケツトはアスベスト自体による、密

スケツトの併用によつて、かろうじて密封してい
るのが現状である。 Therefore, to prevent this leakage, a rubber gasket 5 for the cam chain is separately installed around the cam chain hole.
Measures have been taken to prevent oil leakage, such as providing a groove 6 to accommodate the bolt hole, or providing an O-ring groove 7 around the bolt hole and using an O-ring 8 to prevent oil leakage. The gasket deteriorated due to high temperatures, causing leaks after long periods of use. As mentioned above, gaskets mainly made of asbestos have no desired sealing effect due to the asbestos itself, and the current situation is that sealing is barely achieved by the combined use of O-rings and other gaskets.
また、従来高圧用ガスケツトとして、軟質な金
属単体が用いられたこともあるが、平滑面の金属

円に鋸歯状突起部10を設けて、接触圧を線接触
による集中的な圧力として平面上に完全線接触ル
ープを形成して気密保持が行なわれてきた。 In addition, a single soft metal has been used as a high-pressure gasket in the past, but if the gasket is made of smooth metal, the tightening pressure becomes enormous and a satisfactory sealing effect cannot be obtained. , the thin metal plate is made concentrically corrugated 11 with respect to the hole as shown in FIGS. 4 and 5, and serrated protrusions 10 are provided concentrically on both sides of the metal plate, so that the contact pressure can be controlled by line contact. Airtightness has been maintained by forming a complete line contact loop on a flat surface as a concentrated pressure.
しかし、鋸歯状突起部10を形成した場合、か
なりの締付力を必要とし、一方波形金属ガスケツ
トの場合、波形11が押圧変形によつて、線接触
の効果が失われる問題点がある。 However, when the serrated protrusions 10 are formed, a considerable tightening force is required, and on the other hand, when a corrugated metal gasket is used, there is a problem in that the corrugations 11 are deformed by pressure and the linear contact effect is lost.
また、鋸歯状突起部10や波形11を形成する
ためには製造工程を増加させなければならずコス
トが高くなるという不都合があつた。 Furthermore, in order to form the serrated protrusions 10 and the corrugations 11, the number of manufacturing steps must be increased, resulting in an increase in cost.

覆させており、製造工程が多くなり、コストが高
くなるという不都合があつた。 Furthermore, in order to improve durability such as heat resistance of the gasket, it has been conventionally practiced to form thin films made of heat-resistant rubber, resin, etc. on both surfaces of the gasket. For example, British Patent No. 1166370 proposes a metal gasket coated with fluororesin, and Japanese Utility Model Application Publication No. 48-70054 proposes a resin gasket coated with fluororesin. Proposed. The publication also proposes a gasket in which a circumferential rib is formed around the hole. However, in order to form the circumferential ribs, the resin substrate, which is the base material of the gasket, is bulged outward from the surface and then coated with fluorine resin, which increases the number of manufacturing steps and costs. I had the inconvenience of being expensive.

る。 The present invention has been made in view of these points, and it is possible to extremely easily form a thick swollen portion around the gasket hole to be sealed, thereby improving gasket manufacturing efficiency and reducing manufacturing costs. It is an object of the present invention to provide a method for manufacturing a gasket that can significantly reduce the amount of gas and improve the sealing performance of the gasket.
この目的を達成するために、本発明において

うに構成している。 In order to achieve this objective, in the present invention, a coating liquid made by dissolving heat-resistant rubber, resin, etc. in a solvent with a high surface tension is evenly applied to both surfaces of the gasket to form a film, and the gasket is The structure is such that a thick enlarged portion protruding from both surfaces is formed at the peripheral edge of the gasket hole provided in the gasket to be sealed by utilizing the surface tension of the coating liquid to be applied.

自動的に形成される。 According to the present invention, when the coating liquid is evenly applied to the surface of the gasket, the coating liquid is drawn to the periphery of the gasket hole of the gasket by the surface tension of the coating liquid, protrudes from the surface, and automatically expands the thickened portion. is formed.

れている。 In this embodiment, before the metal plate 17 is coated with the film 13, a surface treatment is performed to roughen the surface into a pear-like texture. That is, both surfaces of a soft metal plate 17 made of aluminum, copper, etc. are subjected to mechanical processing such as blasting or chemical surface treatment such as etching to uniformly form a non-directional fine pear-like texture. to vandalize. FIG. 6 shows an enlarged cross section of the gasket, and both surfaces of the metal plate 17 are satin-like surfaces 12, 12'.

了する。 According to the present invention, for the metal plate 17 formed in this manner, heat-resistant rubber such as fluorine rubber or silicone rubber, fluorine resin, etc. is dissolved in a water-soluble solvent having a high surface tension. Apply the coating liquid
The coating 13 is formed by uniformly applying it to both satin-like surfaces 12, 12' of the metal plate 17. Due to its surface tension, the applied coating liquid is attracted to the peripheral edge 15 of the gasket hole 14, which is a perforation to be sealed, such as an oil hole including a bolt hole, provided in the gasket, and is slightly smaller than the surface of the coating 13 on the flat area. The thickened portions 16, 16' that protrude to the external force are formed, and while this state is maintained, the coating liquid solidifies and the coating is completed.

廉となる。 As described above, in this embodiment, by utilizing the surface tension of the coating liquid, it is possible to form a thickened portion that increases sealing performance at the peripheral edge of the gasket hole simply by applying the same coating liquid to the gasket. Therefore, no special process is required to form the enlarged portion with the same thickness, and the manufacturing process is simple and quick, and the manufacturing cost is low.
なお、本実施例のように金属板17の両表面を

る。 Note that when both surfaces of the metal plate 17 are made to have a satin-like surface 12, 12' as in this embodiment, the surface of the coating 13 formed thereon also becomes a satin-like surface.
Sealing performance is further improved. In other words, both mating surfaces to be sealed are tightly tightened and point-contacted with each other with countless irregular micro-gaps, and these micro-gaps are finely adjusted to form a microscopic, non-directional surface. The labyrinth effect is exhibited and the sealing performance is improved.
また、金属板17としてアルミ等の軟質な素材

変形が可能であり、相手の接合面に対して充分な
密封性能が得られる。 Further, since the metal plate 17 is made of a soft material such as aluminum, it can be sufficiently plastically deformed against the tightening pressure, and sufficient sealing performance against the mating surface can be obtained.
なお、前記実施例は金属性のガスケツトに適用
