従来、上述例の金属被覆ガスケットとしては、例えば、図9に示すように、爪 立て金属板(図示省略)で補強し、且つ、リング形状に打抜き加工した膨張黒鉛 シート23を複数枚重合してなる芯材24の外周面全体を、ステンレス製の金属 薄板25で被覆して断面角形に加圧成形した第1従来例の金属被覆ガスケット2 6と、図10に示すように、爪立て金属板(図示省略)で補強し、且つ、リング 形状に打抜き加工した膨張黒鉛シート27を複数枚重合してなる芯材28の外周 面全体を、ステンレス製の金属薄板29で被覆して断面丸形に加圧成形した第2 従来例の金属被覆ガスケット30と、図11に示すように、コイルスプリングを リング形状に接合してなる芯材31の外周面全体を、アルミニウム製の金属薄板 32で被覆して断面丸形に加圧成形した第3従来例の金属被覆ガスケット33と がある。 Conventionally, as the metal-coated gasket of the above-mentioned example, for example, as shown in FIG. 9, a plurality of expanded graphite sheets 23, which are reinforced by a nail-raising metal plate (not shown) and punched into a ring shape, are polymerized. The metal coating gasket 26 of the first conventional example in which the entire outer peripheral surface of the core material 24 is covered with a thin metal plate 25 made of stainless steel and pressure-molded into a rectangular cross section, and, as shown in FIG. The core material 28 is reinforced with a ring-shaped punched expanded graphite sheet 27, and the whole outer peripheral surface of the core material 28 is covered with a thin metal plate 29 made of stainless steel to have a circular cross section. The pressure-molded second conventional metal-coated gasket 30 and a core material 31 formed by joining coil springs in a ring shape as shown in FIG. The surface round there is a third conventional example of metallization gasket 33 to pressure molding.

しかし、上述の金属被覆ガスケット26,30を製作する場合、シート状に成 形された膨張黒鉛製のシート部材(図示省略)をリング形状に打抜き加工して膨 張黒鉛シート23,27を多数枚製作するので、打抜き加工時に於いて、膨張黒 鉛シート23,27を打抜いた後のスクラップが大量に発生し、材料の歩留りが 悪く、製作コストがアップするという問題点を有している。且つ、金属被覆ガス ケット26,30の膨張黒鉛シート23,27を複数枚重合してなる芯材24, 28の外周面全体と、金属被覆ガスケット33のコイルスプリングを接合してな る芯材31の外周面全体とを金属薄板25,29,32で夫々被覆しているため 、加圧時に於ける圧縮剛性(図8参照)が高く、フランジ面に対する馴染み性が 乏しいという問題点を有している。 However, when the above-mentioned metal-coated gaskets 26 and 30 are manufactured, a large number of expanded graphite sheets 23 and 27 are formed by punching a sheet-shaped expanded graphite sheet member (not shown) into a ring shape. Since it is manufactured, a large amount of scrap is generated after the expanded black lead sheets 23 and 27 are punched during the punching process, the material yield is poor, and the manufacturing cost is increased. Further, the whole outer peripheral surface of the core material 24, 28 formed by superposing a plurality of expanded graphite sheets 23, 27 of the metal-coated gaskets 26, 30 and the core material 31 formed by joining the coil spring of the metal-coated gasket 33. Since the entire outer peripheral surface of is covered with the thin metal plates 25, 29, 32, respectively, the compression rigidity (see FIG. 8) at the time of pressurization is high, and the conformability to the flange surface is poor. There is.
【0004】 この考案は上記問題に鑑み、金属鋼帯と無機テープ材とを巻き重ねてなる芯材 に金属板の外径周縁部を離間したまま被覆して金属被覆ガスケットを製作するこ とにより、材料の歩留りが向上し、フランジ面に対する馴染み性及びシール性の 向上を図ることができる金属被覆ガスケットの提供を目的とする。In view of the above problems, the present invention is to manufacture a metal-coated gasket by coating a core material formed by winding a metal steel strip and an inorganic tape material on an outer peripheral edge of a metal plate while keeping them apart from each other. An object of the present invention is to provide a metal-coated gasket capable of improving the yield of materials and improving the conformability to the flange surface and the sealing property.

この考案は、金属鋼帯と無機テープ材とを円周方向に巻き重ねてなる芯材の外 周面上に金属板を被覆すると共に、該金属板の外径周縁部を離間した状態のまま グロメット加工した金属被覆ガスケットであることを特徴とする。 In this invention, a metal plate is coated on the outer peripheral surface of a core material formed by winding a metal steel strip and an inorganic tape material in a circumferential direction, and the outer peripheral edge of the metal plate is kept in a separated state. It is a grommet-processed metal-coated gasket.
【0006】[0006]
この考案によれば、金属鋼帯と無機テープ材とを円周方向に巻き重ねて芯材を 形成するので、従来例のように膨張黒鉛シートを打抜き加工するのに比べて材料 の歩留りが良く、使用材料を無駄なく活用して、製作コストの低減を図ることが できる。しかも、芯材の外周面上に被覆した金属板の外径周縁部を離間している ため、加圧時に於ける圧縮剛性が低く、フランジ面に対する馴染み性及びシール 性の向上を図ることができる。さらに、金属鋼帯を円周方向に巻き重ねているの で、加圧時に於いて芯材が外径方向に変形するのを積極的に防止することができ ると共に、芯材の外周面上に金属板を被覆(グロメット加工)しているため、膨 張黒鉛材や天然マイカ材等のシール材がガス圧力により吹き飛ばされるのを確実 に防止することができる。 According to this invention, the metal steel strip and the inorganic tape material are circumferentially wound to form the core material, so that the yield of the material is better than that obtained by punching the expanded graphite sheet as in the conventional example. By using the used materials without waste, the manufacturing cost can be reduced. Moreover, since the outer peripheral edge portion of the metal plate coated on the outer peripheral surface of the core material is separated, the compression rigidity at the time of pressurization is low, and the conformability to the flange surface and the sealability can be improved. . Furthermore, since the metal steel strips are wound in the circumferential direction, it is possible to prevent the core material from deforming in the outer diameter direction at the time of pressurization and at the same time, on the outer peripheral surface of the core material. Since the metal plate is coated (grommeted) on the sheet, it is possible to reliably prevent the sealing material such as expanded graphite material or natural mica material from being blown off by gas pressure.

After being formed into a shape, it is processed into a tape shape.
【0011】 図4に示す第3実施例の金属被覆ガスケット11は、図5及び図6に示すよう に、テープ状に形成したステンレス製(SUS316L)の金属箔12(厚み5 0μm)の上下両面に、テープ状に形成した膨張黒鉛テープ13,13(厚み0 .5mm)を夫々接着して複合テープ14を形成し、同複合テープ14を皺付け加 工(クリニクル加工)して軸方向に重合しながらスパイラル状に巻き重ねて一つ の芯材15を形成する。この後、同芯材15の外径周面部15aを除く残りの外 周面上にステンレス製(SUS310S)の金属薄板16(厚み0.2mm)を被 覆し、同金属薄板16の外径周縁部16a,16aを円周方向に離間した状態の ままグロメット加工して、断面角形(図4参照)又は断面丸形(図7参照)に加 圧成形した金属被覆ガスケット11である。As shown in FIGS. 5 and 6, the metal-coated gasket 11 of the third embodiment shown in FIG. 4 is made of a stainless steel (SUS316L) metal foil 12 (thickness: 50 μm) formed on both upper and lower surfaces.

On the other hand, one core material 15 is formed by spirally winding. Then, a stainless steel (SUS310S) thin metal plate 16 (thickness: 0.2 mm) is covered on the remaining outer peripheral surface of the core material 15 excluding the outer peripheral surface portion 15a. 16a, 16a is a metal-coated gasket 11 that is grommet-processed while being spaced apart in the circumferential direction, and is press-formed into a rectangular cross section (see FIG. 4) or a round cross section (see FIG. 7).
【0012】 図7に示す第4実施例の金属被覆ガスケット17は、上述の第3実施例に於い て用いられる膨張黒鉛テープ13,13に代えて、テープ状に形成したステンレ ス製(SUS316L)の金属箔18(厚み50μm)の上下両面に、テープ状 に形成したフロゴパイト製(金雲母)又はマスコバイト製(白雲母)のマイカペ ーパー19,19(厚み0.45mm)を夫々接着して複合テープ20を形成し、 同複合テープ20を皺付け加工(クリニクル加工)して軸方向に重合しながらス パイラル状に巻き重ねて一つの芯材21を形成する。この後、同芯材21の外径 周面部21aを除く残りの外周面上にステンレス製(SUS310S)の金属薄 板22(厚み0.2mm)を被覆し、同金属薄板22の外径周縁部22a,22a を円周方向に離間した状態のままグロメット加工して、断面丸形(図7参照)又 は断面角形(図4参照)に加圧成形した金属被覆ガスケット17である。The metal-coated gasket 17 of the fourth embodiment shown in FIG. 7 is made of stainless steel (SUS316L) formed in a tape shape in place of the expanded graphite tapes 13, 13 used in the above-mentioned third embodiment. ) Metallic foil 18 (thickness: 50 μm) on both upper and lower surfaces are bonded with tape-shaped phlogopite (phlogopite) or muscovite (muscovite) mica papers 19, 19 (thickness 0.45 mm), respectively.

The metal-coated gasket 17 is formed by grommeting 22a, 22a while keeping them separated from each other in the circumferential direction, and press-molding them into a round cross section (see FIG. 7) or a square cross section (see FIG. 4).
【0013】 上述する金属被覆ガスケット1,6,11,17の比較例として、例えば、金 属フープ2と膨張黒鉛フィラー材3とを巻き重ねてなる芯材4の外周面上に金属 薄板5を被覆した第1実施例の試験品Aと、金属フープ7とマイカペーパー8と を巻き重ねてなる芯材9の外周面上に金属薄板10を被覆した第2実施例の試験 品Bと、膨張黒鉛シート23を複数枚重合してなる芯材24の外周面上に金属薄 板25を被覆した第1従来例の試験品Cとを同一形状寸法(内径76mm×外径8 4mm×厚み5mm)に形成して同一条件で圧縮試験を行なった。As a comparative example of the metal-coated gaskets 1, 6, 11, and 17 described above, for example, a metal thin plate 5 is provided on the outer peripheral surface of a core material 4 formed by winding a metal hoop 2 and an expanded graphite filler material 3 together. The coated test product A of the first embodiment, the test product B of the second embodiment in which the metal thin plate 10 is coated on the outer peripheral surface of the core material 9 in which the metal hoop 7 and the mica paper 8 are wound, and the expansion The same shape and dimensions as the test product C of the first conventional example in which the metal thin plate 25 is coated on the outer peripheral surface of the core material 24 formed by polymerizing a plurality of graphite sheets 23 (inner diameter 76 mm × outer diameter 84 mm × thickness 5 mm) Then, a compression test was performed under the same conditions.
【0014】 すなわち、図8に示すように、上述の試験品A,B,Cに対して締付け面圧を 均等に付加したときの圧縮応力を比較した場合、従来例の試験品Cは、芯材24 の外周面全体を金属薄板25で被覆しているため加圧時の圧縮剛性が高く、本考 案の試験品A,Bは、芯材4の外周面上に被覆した金属薄板5の外径周縁部5a ,5aと、芯材9の外周面上に被覆した金属薄板10の外径周縁部10a,10 aとを円周方向に離間しているため加圧時の圧縮剛性が低く、従来例の試験品C に比べて本考案の試験品A,Bの方が弾性変形率が大きく、フランジ面に対する 馴染み性及びシール性に優れていることが証明される。That is, as shown in FIG. 8, when comparing the compressive stresses when the tightening surface pressures are evenly applied to the above-mentioned test products A, B, and C, the test product C of the conventional example is Since the entire outer peripheral surface of the material 24 is covered with the metal thin plate 25, the compression rigidity at the time of pressurization is high, and the test products A and B of the present invention have the metal thin plate 5 coated on the outer peripheral surface of the core material 4. Since the outer peripheral edge portions 5a, 5a and the outer peripheral edge portions 10a, 10a of the metal thin plate 10 coated on the outer peripheral surface of the core material 9 are circumferentially separated from each other, the compression rigidity at the time of pressurization is low. It is proved that the test products A and B of the present invention have a larger elastic deformation rate than the test product C of the conventional example, and are excellent in the conformability to the flange surface and the sealing property.
【0015】 以上の結果が示すように、金属フープ2と膨張黒鉛フィラー材3又は金属フー プ7とマイカペーパー8を巻き重ねて芯材4,9を夫々形成し、金属箔12と膨 張黒鉛テープ13又は金属箔18とマイカペーパー19を巻き重ねて芯材15, 21を夫々形成するので、従来例のように膨張黒鉛シート23を打抜き加工する のに比べて材料の歩留りが良く、使用材料を無駄なく活用して、製作コストの低 減を図ることができる。As shown by the above results, the metal hoop 2 and the expanded graphite filler material 3 or the metal hoop 7 and the mica paper 8 are wound to form the core materials 4 and 9, respectively, and the metal foil 12 and the expanded graphite are formed. Since the core materials 15 and 21 are formed by winding the tape 13 or the metal foil 18 and the mica paper 19 on top of each other, the yield of the material is good and the material used is better than punching the expanded graphite sheet 23 as in the conventional example. It is possible to reduce manufacturing costs by utilizing the wastefulness.
【0016】 しかも、芯材4,9,15,21の外周面上に被覆した金属薄板5,10,1 6,22の外周部分を離間しているため、加圧時に於ける圧縮剛性が低く、フラ ンジ面に対する馴染み性及びシール性の向上を図ることができる。さらに、金属 フープ2,7又は金属箔12,18を円周方向に巻き重ねているので、加圧時に 於いて、芯材4,9,15,21が外径方向に変形するのを積極的に防止するこ とができると共に、芯材4,9,15,21の外周面上に金属薄板5,10,1 6,22を被覆(グロメット加工)しているため、膨張黒鉛材や天然マイカ材等 のシール材がガス圧力により吹き飛ばされるのを確実に防止することができる。Moreover, since the outer peripheral portions of the metal thin plates 5, 10, 16 and 22 coated on the outer peripheral surfaces of the core materials 4, 9, 15, 21 are separated from each other, the compression rigidity at the time of pressurization is low. It is possible to improve the familiarity with the flange surface and the sealing property. Furthermore, since the metal hoops 2, 7 or the metal foils 12, 18 are wound in the circumferential direction, it is possible to positively deform the core materials 4, 9, 15, 21 in the outer diameter direction at the time of pressing. In addition to the above, the thin metal plates 5, 10, 16, and 22 are coated (grommeted) on the outer peripheral surfaces of the core materials 4, 9, 15, and 21, so that the expanded graphite material and natural mica can be prevented. It is possible to reliably prevent the sealing material such as the material from being blown off by the gas pressure.

The material 15 may be formed, and the outer peripheral edge portions 16a, 16a of the metal thin plate 16 coated on the outer peripheral surface of the concentric material 15 may be grommet-processed while being separated from each other.
