Definitions

  • the present invention relates to a stamping method, in which a plurality of depressions is impressed into a material web to be embossed by at least one stamping die. Furthermore, the invention is directed to a profile element with corresponding recesses.
  • Such depressions often called beads, are usually produced for stiffening the material web.
  • the problem with this is that with appropriately deepened depressions, the web of material after the embossing process is often no longer 100% flat, but has an undesirable waviness. This waviness occurs all the more, the deeper the recesses are formed and the larger the area of the recesses relative to the total surface of the material web.
  • this object is achieved in that before the embossing of the recesses in each case the recesses associated equalization sections are generated in the material web, wherein the compensation sections so are arranged and configured relative to the associated recesses to be shaped in the following, that material stresses occurring due to the embossing process are essentially absorbed by the compensating sections, so that a waviness or bulging of the material web outside the depressions caused by the embossing process is prevented or at least minimized.
  • the compensation sections are introduced before the impressions of the depressions in the material web in order to record the material stresses occurring during the subsequent embossing process can occur.
  • the output sections must be arranged and configured in such a way that the material stresses occurring during the embossing of the depressions extend in the direction of the previously created compensation sections and are absorbed by them. Only in this way an undesirable waviness or bulging of the material is prevented.
  • At least a part of the compensating sections or all compensating sections are arranged so that they are respectively disposed within the recesses.
  • the arrangement of the compensation sections within the recesses ensures that the material stresses occurring during the embossing process can not flow into the unembossed material arranged outside the recesses, but directly into the compensation sections arranged within the recesses. It is thereby achieved that the unembossed regions of the material web remain substantially free of material stresses occurring as a result of the embossing process.
  • at least a part of the depressions or all depressions are formed contiguous. As a result, an even better distribution of the material stresses occurring during the embossing process and thus a better absorption by the compensating sections is possible.

In the case of an embodiment, for example as folded material regions and / or material regions with a lattice structure, these can absorb the material stresses.
  • the specially formed material areas are deformed according to the material stresses occurring, for example, folded material areas formed in the form of a bellows are compressed or expanded, but due to the special design of the compensating sections, there is no or only insignificant one in this case Effect of material stresses on the areas of the material web located outside the compensation sections.

Abstract

L'invention concerne un procédé d'estampage selon lequel une pluralité de creux (5, 16, 24) sont estampés par au moins un poinçon d'estampage dans une bande de matériau (6) à estamper. Avant l'estampage des creux, des sections de compensation (8, 15, 25) respectivement associées aux creux sont produites dans la bande de matériau. Les sections de compensation sont disposées et conçues par rapport aux creux associés à estamper par la suite de telle manière que des tensions du matériau dues au processus d'estampage soient pratiquement absorbées par les sections de compensation. Cela empêche ou réduit au moins à un minimum une ondulation ou un bombement de la bande de matériau provoqué par le processus d'estampage. L'invention concerne également un élément profilé fabriqué avec un tel procédé.
