Abstract

A method is provided for producing centering elements in a molded rubber seal that is reinforced with metal. Metal is cut out of at least one edge area of the metal element and the freed material is shaped by being bent upwards away from the plane of the metal element. Elastomer material is then molded around the bent material above the cavity created by the shaping process, in order to produce a pre-definable final contour.

Description

  • The invention concerns a procedure for producing centering agents in the field of metallically strengthened molded rubber gaskets.
  • The utility model DE 20105250 UI illustrates a flat gasket with clamp plates to its fixing on a sealing surface. It is a metallic flat gas gasket in which no Elastomer material is formed and not a molded rubber gasket.
  • A housing cover for crankshaft cases is taken from DE 4134316. Axial noses are provided in the screw thread gears, which serve for centering and can be molded with Elastomer material. A connection between the Elastomer sealing lips and the Elastomer material is not provided, so that the noses must be produced in a separate working cycle. This housing cover has nothing in common with a molded rubber gasket.
  • Molded rubber gaskets are used for example in the field area of internal combustion engine valve caps or similar sealing casing parts. However, these molded rubber gaskets, which are to some extent relatively unstable in their form, must be assembled in the sealing area. Here, assembly aids such as pressed-in or riveted metal pegs or molded plastic or rather Elastomer contours are used as centering agents. The economic efficiency of the previously produced molded rubber gaskets is unfavorably influenced by these additional metal pegs.
  • In the application of molded plastic or Elastomer contours, negative influences are possibly recorded with regard to an Elastomer or material shrinkage.
  • A housing cover is taken from DE-C 4 134 316, with several distributed screw thread holes in a radial flange surface of the cover arranged on the circulation as well as agents for a location-suitable fixing and centering of the cover opposite the crankshaft case. The centering agents are formed by at least two axial extending noses in the direction of the crankshaft case, which are bound in one clump with the radial flange surface. The noses are in corresponding drill-holes insertable with the screw thread holes. On the outer circulation of the noses, an elastic layer can be arranged, which is integrally molded in a separate working cycle on the housing cover.
  • A sealing has become known through the DE-C 4 223 486 with an insert that is enclosed by Elastomer material, in which the insert features holes for taking in screws and, in the area of the holes, grout limiters formed out of the insert are provided. The latter are formed by the folding-over of hole borders, so that in the hole area a double coating thickness of the insert is produced.
  • The basis of the task for the invention is to provide a procedure for the production of centering agents in the field of metallically strengthened molded rubber gaskets which involve a high positioning accuracy of molded rubber gaskets. In addition, a metallically strengthened molded rubber gasket is to be planned which can easily be made and safely used for positioning in the sealing area.
  • This task is solved in accordance with the invention by the characteristics of patent claim 1. Further advantageous formations of the procedure according to the invention are taken from the accompanying claims below.
  • Compared to the general state of technology, therefore, a possibility is shown to produce integral centering agents in the field of molded rubber gaskets. An economical solution is presented by these measures that contain no additional components (metal pegs or the like) and involve a very high positioning accuracy of the peg molded with Elastomer material.
  • Negative influences of the Elastomer shrinkage can be markedly reduced. According to demands on the centering, a strengthening of the Elastomer geometry can be realized, in which even greater heights of the centering peg are conceivable.
  • The object of invention is presented on the basis of an explanatory example in the drawing and is described as follows. It shows:
  • FIG. 1 Partial view of a metallic element with a free cut and material formed out of it;
  • FIG. 2 Partial view according to FIG. 1 with molded rubber gasket;
  • FIG. 3 Cross-section through the metallic element in the area of the molded material formed with Elastomer material.
  • FIG. 1 shows as a partial view a metallic element 1, in whose border area 2 a free cut 3 predetermined contour was brought in. The free cut material 4 is bent out under formation of a somewhat peg-like contour from level 5 of the metallic element 1 by essentially 90°, so that a free space 6 is produced, which forms a molding canal.
  • The metallic element is represented in FIG. 2, on which the molded rubber gasket 7 is now molded. Above the free space 6, Elastomer material in the direction of the somewhat peg-like formed material 4 was led in the same working cycle, in which the material 4 was molded from Elastomer material 8. The peg 4, originally provided with a multi-angular cross section, exhibits a somewhat circular contour in the cross section after its molding with Elastomer material 8.
  • FIG. 3 shows a cross section through the peg-like material 4 in the joint on its jacket with the Elastomer material 8. It is noticeable that the material 4 is formed by about 90° from level 5 of the metallic element 1. The given Elastomer material in the free space 6 (mold canal) is defined with the reference sign 9.

Claims (3)

1. Procedure for the production of centering agents in the field of metallically strengthened rubber mold gaskets, in which in a border area of a metal element at least one free cut is made and material of the metal element bent out of a plane of the metal element to create a free space; introducting elastomer material into the free space and around the outwardly bent material during the formation of elastomeric sealing features of the gasket.
2. Procedure according to claim 1, wherein the material is bent 90° from the plane of the metal element.
3. Procedure according to claim 1, wherein the bent material is formed with polygonal cross section of the metal element and afterwards molded to a substantially circular cross section with elastomer material.
