  • the invention relates to a composite workpiece, a method for producing a composite workpiece and a system of a composite workpiece and a detector device.
  • Generic composite workpieces are well known and typically include a metallic cover layer and a non-metallic core layer. With such composites, positive properties of the metal and the non-metal in a single workpiece can be combined in an advantageous manner. For example, components or individual components are produced from composite workpieces for the vehicle industry in order to deliberately save weight on the body, for example.

  • markings can be used, for example, in a fully automated manufacturing process with which the target product is to be produced, so that individual composite pieces are recognized and further treated according to their marking in the manufacturing process.
  • You can also use markers to trace individual composites or the target product.

  • the present invention solves the problem by a composite piece having at least one metallic cover layer and a non-metallic core layer, wherein the metallic cover layer and the non-metallic core layer are connected to one another, wherein the metallic cover layer in a marking region on its side facing the non-metallic core layer has a profile for marking having the composite piece.
  • the composite work piece according to the invention has a profile, in particular a surface profile for marking the composite work piece on the side of the metallic cover layer facing the non-metallic core layer. This has the positive effect that a user surface of the composite remains unaffected and can be used in the usual way for coatings, color or the like.
  • the profile used for the marking in particular the surface profile, remains unrecognized from the outside, so that such an "invisibility" of a mark which can not be read without corresponding detection means can be used as theft protection Moreover, the mark can not be changed or completely eliminated without complete destruction of the composite work piece

It can thus be ensured that the marking of the composite workpiece made in the form of the profile, in particular the surface profile, has essentially no influence on the material properties of the composite material in the marking area, since such a profile, in particular surface profile, represents a comparatively insignificant change for the composite workpiece.

This facilitates the search for the marking by means of a detector device, since a user of the detector device is given the position of the marking region can. Furthermore, it is conceivable that there are several marking areas, so that the composite workpiece can be divided in a further manufacturing step and each of the sub-elements receives a marking area. It is also conceivable that the sub-elements are punched out of the composite workpiece and the marking area is positioned depending on the subsequent punching process.

  • the profile in particular the surface profile is introduced into the metallic cover layer and then the metallic cover layer is oriented such that the side of the metallic cover layer is aligned with the non-metallic core layer and rests against this non-metallic core layer.
  • the profile formation is realized by a laser engraving, a spark erosion or a mechanical erosion.
  • the non-metallic core layer for connecting the metallic cover layer to the non-metallic core layer is converted into a flow state.
  • the non-metallic core layer is heated for this purpose.
  • the fluidity of the non-metallic core layer present during bonding advantageously makes it possible to balance between an area with a profile, in particular with a surface profile and an area without a profile, so that a uniform thickness of the finished composite workpiece can be ensured.
  • the composite workpiece is formed in the marking area. Because of the comparatively low tread depth, the profile, in particular the surface profile, is essentially preserved. Accordingly, the marking area can advantageously be positioned independently of the forming process, so that one is accordingly free in the selection of the position of the marking area.
