も良い。 As schematically shown in FIG. 4, the previously devised continuous manufacturing apparatus for cylinder head gaskets uses a punching press 2 to form a sheet 1 that is fed out from a coil 1a of a long sheet for gaskets in the direction of arrow a. As shown in Fig. 5, bore holes 3, pilot holes 4, water holes, oil holes, etc. are drilled, and a temporary fitting device 5 is drilled.
A metal fitting is fitted inside a predetermined hole using a screwdriver, and several parts of the upper end of the cylindrical part of the metal fitting that protrudes from the upper surface of the sheet 1 are partially cut in order to prevent the metal fitting from falling out from inside the hole while the sheet 1 is moving. The upper end of the cylindrical part of each metal fitting is completely crimped and expanded using the metal fitting crimping press device 6, and then the metal fittings are strongly pressed by the metal fitting crimping press device 7 to secure the metal fittings to the edge of the bore hole, etc. Then, gaskets 9 are punched out one by one by a peripheral punching press 8, and the waste material 1b is cut into pieces by a cutter 10 and collected in a storage box 11. In the example shown in FIG. 4, the metal fittings are fixed to the seat using press devices 6 and 7, but depending on the accuracy required for the cylinder head gasket being manufactured, one press device may be used. Alternatively, the metal fittings may be fixed to the periphery of the hole in the sheet all at once.

とを備えている。b. Structure of the invention (means for solving the problem) In the cylinder head gasket continuous production apparatus of the invention, the above-mentioned metal fittings fitted into holes drilled in a long sheet for cylinder head gaskets are used. A pair of left and right supporting members are provided on both sides of the long sheet that is sent during the production of cylinder head gaskets near a press device for fixing the sheet to the peripheral edge of the hole in the sheet. Each of the supporting members is given upward elasticity, and there is a gap between both supporting members that is parallel to each other and is sufficient to allow the long sheet fitted with the metal fittings to pass freely between them. The sheet flotation device includes a sheet flotation device formed by extending a pair of upper and lower guide rods, and a tension applying device provided in front of the sheet flotation device to apply tension to the elongated sheet in a direction opposite to the traveling direction of the elongated sheet.
（作用）
上述の様に構成される本考案のシリンダヘツド
ガスケツトの連続製造装置の作用は次の通りであ
る。(Operation) The operation of the cylinder head gasket continuous manufacturing apparatus of the present invention constructed as described above is as follows.

持棒が上昇し、両支持棒の間を通過しつつ送られ
る長尺シートが上記プレス装置の下型から浮上し
て、この長尺シートに嵌着された金具が下型の角
部等に引つ掛かるのを防止する。 First, when feeding long sheets in the production of cylinder head gaskets, the upper die of each press is raised, so a pair of support members installed on both the left and right sides of the long sheets are used. elastically rises, a pair of upper and lower support rods whose ends are respectively supported by both support members rises, and the long sheet being fed while passing between both support rods floats up from the lower die of the press machine. This prevents the metal fittings fitted to the long sheet from getting caught on the corners of the lower mold.

く金具の固定等を行なう事が出来る。 When the feeding of a long sheet is temporarily stopped and the upper mold of the press is lowered to fix the metal fittings, etc.
A long piece of paper whose both ends are supported by supporting materials is pushed down elastically by the sheet pressurized by the upper mold, and is supported by this support rod while floating above the lower mold. Since the sheet is in contact with the upper surface of the lower mold of the press device, the metal fittings can be fixed without greatly bending the long sheet.

装置の上型下面からのシート剥離は確実に行なわ
れる。 When attempting to raise the upper mold after fixing the metal fittings, etc., there is a tendency for the long sheet to rise while remaining attached to the lower surface of the upper mold. Since the long sheet is fed while passing between the pair of support rods, the upward movement of the long sheet is prevented by the upper support rod, and the sheet is reliably peeled from the lower surface of the upper die of the press device.
また、張力付与装置により長尺シートに張力を
付与しているため、金具のかしめ作業終了に伴つ
て上型が上昇した場合シートが下方にたわんだ状

4 are provided in front and behind the lower die 14 as described above, and the sheet 1 is moved through the guide rods 29 and 3 as shown by the arrow a in FIG.
When the sheet 1 is advanced through the gap between 0 and 0, if the upper mold 19 is raised, the sheet 1 is directed upward via the arms 25 by the springs 28 in front and behind the lower mold 14, as shown in FIG. Guide rod 30 with elasticity
Since the corner portion 20a of the metal fitting 20 temporarily fixed to the sheet 1 does not come into contact with the corner portion 14a of the lower die 14, etc., the sheet 1
can proceed smoothly. If the sheet 1 is light, it is not necessary to provide the sheet flotation devices 24, 24 at the front and rear of the lower die 14 as shown in FIGS. The same effect can be obtained even if it is provided.

の筒部上端をかしめ広げる。 As the sheet 1 advances, the metal fitting 20 is moved to the upper die 19.
The caulking position between the sheet 1 and the lower die 14 is reached, and the sheet 1
When it pauses, the upper mold 19 descends and the metal fitting 20
Caulk and widen the top end of the cylinder.

決められると共に不動になる。 When the upper mold 19 descends in this manner, the guide pin 22 on the lower surface of the upper mold enters the pilot hole 4 of the sheet 1, and then the guide pin 22 protruding below the pilot hole 4 lowers. The sheet 1 enters the guide hole 23 of the mold 14 to accurately determine the positions of the sheet 1, the upper mold 19, and the lower mold 14. After that, upper mold 1
9 is lowered sufficiently, the spring 18
Since the lower surface of the push-out plate 17 suspended from the lower surface of the upper mold 19 presses the upper surface of the sheet 1, the positions of the metal fitting 20 and the upper mold 19 and the lower mold 14 are accurately determined and immovable.
この状態から上型１９を更に下降させる事によ
り、シート１は上型１９の下面に押され少し下降
して下型１４の上面に密着し、第２図に示す様に
金具２０の筒部上端が全体的にかしめられる。 By further lowering the upper mold 19 from this state, the sheet 1 is pushed by the lower surface of the upper mold 19, descends a little, and comes into close contact with the upper surface of the lower mold 14, and the upper end of the cylindrical part of the metal fitting 20 is shown in FIG. is caulked as a whole.

ない。 When the upper mold 19 descends in this manner, the lower guide bar 30 is pushed downward by the sheet 1;
Since the arms 25 supporting both ends of the seat rotate downward while elastically deforming the spring 8, the lowering of the seat 1 is not hindered. Since the elasticity of the spring 28 is weak enough to support the sheet 1 above the lower die 14, the arm 25 can be easily rotated, and there is no large resistance to the lowering of the sheet 1. No.

すれば良い。 A pair of rollers 32, 32 provided at the right end of FIG. 1 so as to sandwich the sheet 1 from above and below is a tensioning device for the sheet 1, and the rollers 32, 32 are tension-applying devices for the sheet 1. It rotates in the opposite direction to the feeding direction of sheet 1 to apply a weak tension to sheet 1. By providing such tension applying rollers 32, 32, when the upper mold 19 rises as the caulking work of the metal fittings 20 is completed, the sheet 1 is bent downward as shown in FIG. The tensioned state shown in FIG. 1 is immediately restored, and the feeding operation of the sheet 1 can be resumed quickly. In other words, if the cylinder head gasket sheet is somewhat lacking in rigidity, the sheet will tend to bend downward due to its own weight, but a tensioning device applies tension to the sheet in the opposite direction to the direction in which the long sheet travels. Therefore, this deflection can be reduced and the long sheet can move smoothly. If the rollers 32, 32 become a hindrance to the lowering of the upper die 19, both rollers 32, 32 may be elastically supported by a structure similar to that of the guide bars 29, 30.

This not only prevents the metal fittings attached to the continuously fed long sheets from getting caught on the corners of the lower die of the press machine, but also prevents the sheet from getting caught in the upper die when the upper die rises at the end of the press operation. Since the sheet does not rise while adhering to the bottom surface of the sheet, the sheet can be fed smoothly and high-quality cylinder head gaskets can be manufactured efficiently.
