Definitions
- the invention relates to a method for mechanically connecting, at least two layers having flat gaskets.
- the metal gasket which is designed such that it is arranged between opposing surfaces of a cylinder block and a cylinder head.
- the metal gasket includes a pair of elastic metal plates provided with first bore holes formed corresponding to the cylinder bores and with beads formed along the circumference of the first bore holes. Further, a balancing member is provided which is provided with the second bore holes opposite the first bore holes and which is laminated between the elastic metal plates.
- the elastic metal plates have connecting portions, wherein the metal plates and the compensating element are connected to each other by caulking.
- a stamp is used, which mechanically deforms the material in the respective connecting region of the metal plates and of the compensating element. With the aid of a further punch, an effective material deformation can be generated in the region of the respective layers, by means of which a firm bond of the individual layers is produced.
- the invention has for its object to provide a method for mechanically connecting, at least two layers having flat gaskets, such as cylinder head gaskets, flange gaskets or the like, provide, the composite can be realized in the simplest way without additional materials or fasteners.
- a flat gasket in particular a multi-layer metallic cylinder head gasket, wherein a detachable connection of the individual layers with one another should be possible.
- This object is achieved by a method for mechanically connecting flat gaskets having at least two layers by positioning the individual layers in the region of a tool, at least one punch having an approximately circular cross-section partially cutting the layers at defined points of the respective connection region and outside at least parts of the remaining material are deformed to form bending regions, such that the respective cutting region is rounded and the respective bending region is rectilinear, wherein burrs formed in the cutting region of at least one of the layers form a releasable clamping connection with the material of at least one further layer be brought into operative connection.
- a flat gasket comprising at least two layers which have similar hole patterns, wherein the individual layers are detachably connected to each other by clamping, wherein the respective connection region has an approximately circular cross-section and at defined locations cutting areas and outside the cutting areas has bending areas , wherein the respective cutting area is rounded and the respective bending area is rectilinear and burrs formed in the cutting area of at least one of the layers are pressed into the material of at least one further layer, respectively hooked with further burrs of the further layer.
- the individual, in particular metallic, layers of the flat gasket are connected to each other in a type of punching process mechanically, but releasably at predeterminable points.
- a punch on several sides preferably three sides
- the material in the respective connection area is merely held and mechanically deformed.
- the respective position during the pressing process at defined locations is cut (preferably three places), such that even burrs remain that either press under pressure into another position, or interact with burrs another layer in operative connection. Both processes a clamping connection of the individual layers is achieved.
- the cutting areas are designed by their dimensioning so that they are executed in percentage smaller or equal to the same size, as the substantially rectilinear bending areas.
- up to six (metallic) layers can be detachably connected to each other, wherein the compound of the layers is carried out at different points of the flat gasket in one operation.
- connection of the individual layers can, if necessary, be solved again, so that after replacement of a defective by a technically perfect position, the connection can then be restored under pressure.
- the subject invention is illustrated by an exemplary embodiment in the drawing and will be described as follows. Show it.
- FIG. 1 is a schematic diagram of the tool that can be used to create a connection region in various views or sections;
- Figure 2 single representation of the respective cutting and bending area in a connection area.
- the machining tool 1 shows a partial perspective view of the schematic structure of a single machining tool 1.
- the machining tool 1 includes an elongated punch 2 with an approximately circular lower hole surface 3.
- a flat gasket such. a cylinder head gasket, not shown here
- connecting areas are generated.
- the punch 2 is flattened on three sides 4,5,6 and rounded on another three sides 7,8,9. Each connecting region thus forms, on the one hand, cutting regions 7 to 9 and, on the other hand, bending regions 4 to 6.
- FIG. 2 shows a partial view of a flat gasket 13, which in this example consists of three metallic layers 10, 11, 12 and is designed as a cylinder head gasket.
- the cylinder head gasket 13 includes not shown combustion chamber through holes, media through holes, and screw through holes.
- the metallic layers 10 to 12 of the cylinder head gasket 13 are mechanically but releasably connected at different points 14 by clamping.
- the individual connecting region 14 that can be seen here includes cutting regions 7 and bending regions 4, wherein this connecting region 14 has in each case three cutting regions 7 to 9 and three bending regions 4 to 6 in an alternating arrangement.
- the respective connecting region 14 a mechanical clamping of materials (burrs T) of the layers 10 to 12 takes place, wherein the individual layers 10, 11, 12 are detachably connected to one another by clamping. Furthermore, the punch 2 with the cutting regions 7 and the bending regions 4 can be seen.
- the reference numeral 2 designates a lower tool part which has a corresponding recess 15.
- the layers 10-12 can be easily separated.
- the defective position is replaced by a technically perfect position and connected by pressure again with the other layers.

Abstract
L'invention concerne un procédé d'assemblage mécanique de joints plats (13) comportant au moins deux couches (10, 11, 12), procédé selon lequel les couches (10-12) individuelles sont placées dans la zone d'un outil (2'), au moins un poinçon (2) à section presque ronde (13) coupe partiellement les couches en des emplacements définis de la zone d'assemblage (14) correspondante et à l'extérieur de la zone de coupe (7,8,9) correspondante, au moins des parties du matériau restant sont façonnées pour former des zones de flexion (4,5,6) de manière à ce que la zone de coupe (7-9) correspondante soit arrondie et la zone de flexion (4-6) correspondante soit linéaire. Les arêtes (7') formées dans la zone de coupe (7-9) d'au moins une des couches (10-12) sont en liaison active avec le matériau d'au moins une autre couche (10-12) pour former un assemblage par serrage libérable.
