  • the present invention relates to a method according to the Preamble of claim 1 for applying a superficial Lubricant carrier layer on a subsequent in a material to be deformed using a cold forming process, in particular on a wire material to be deformed in the drawing process, being subsequent to the lubricant carrier layer a solid lubricant can be applied, and for formation the lubricant carrier layer in the dry phase carrier material is applied.
  • the invention also relates to the preamble of claim 14 a special device for performing this procedure as well as according to the preamble of each of claims 10 to 12 a dry carrier material for use in the method according to the invention, i.e. For education the lubricant carrier layer.
  • this lubricant carrier layer can be used can also be formed by so-called phosphating (see Lueger, Volume 8, page 546).
  • the lubricant carrier fills the valleys of the rough material surface from (underground filler) and thus serves for anchoring of an actual separating lubricant to be applied subsequently.
  • It is wire drawing today usually around a solid lubricant based on soap, especially metal soap base, e.g. Lithium stearate (so-called “drying", compare Lueger, Volume 8, page 124).
  • the wire is on every drawing pulled through a carbide or diamond die and reduced and elongated in cross-section (plastic, in essential non-cutting deformation).
  • the drawing nozzle is one Upstream container in which the solid lubricant in Powder form, and the wire runs through it Grease and constantly takes particles with them, which then in form a "lubricating film" in the drawing nozzle.
  • the present invention is based on the object Effort for applying a lubricant carrier layer and preferably also for the necessary material pretreatment to reduce, but at least constant good lubrication during the subsequent To ensure cold forming process. In particular, should even productivity thanks to improved lubrication properties still be increased.
  • A is thus used to form the lubricant carrier layer special dry carrier material, i.e. one in the "dry phase", not in water or in a other solvent dissolved carrier material, in cold Condition (approximately normal room temperature) immediately on the Metallic bright surface applied.
  • This preferably powdery and / or granular dry material is preferably mechanical by pressing or pressing upset. So there is no need for complex work wet chemical process.

  • the preferred contained “non-reactive Component "(fillers) ensures good adhesion to the Material surface by - due to a low Particle size of the fillers - fills in the unevenness and thus acts as a primer.
  • the "Reactive component” can - depending on the amount of it in the Dry substance contained proportion - already a sufficient Lubrication for the subsequent forming process (e.g. wire drawing), so that a additional lubricant can be completely unnecessary.
  • an "actual lubricant” is added, which is a known solid lubricant with Metal soap shares can act.
  • the soap content of the dry carrier material according to the invention and the dry lubricant then react in particular by balancing the pH in such a way that good adhesion of the Dry lubricant over the manufactured according to the invention Lubricant carrier layer is reached on the material.

  • the coating is through the invention extraordinarily simple and economically feasible. It only needs the dry carrier material to the pressure bodies to be filled into the container. Below then only needs to be ensured that always there is a sufficient "reservoir", i.e. the Dry material only needs to be consumed in each case to be added. Disposal or general emptying advantageously omitted entirely.
  • the pressure body can advantageously also from the dry carrier material be formed by the fact that it consists of larger particles or parts in granulate or pellet form. Different shapes are preferred and / or sizes combined so that a coarse fraction and a fine fraction arises, the coarse fraction acts as a pressure body and at the same time under Formation of finer particles, which then grinds from the larger particles on the material surface mechanically be pressed on. The fine fraction is thus created practically “by itself", so that essentially only the rough portion needs to be refilled.
  • Every drawing station 2 consists, in a manner known per se, of a drawing nozzle 4 (Drawing die, in particular made of diamond or hard metal) and one of these upstream lubricant container 6, in which a solid lubricant in particular in powder form Metal soap base through which the wire material 1 is pulled through so that lubricant particles on the wire adhere and in the direction of arrow 7 into the drawing nozzle 4 be taken along and form a lubricating film there.

  • This Screw conveyor 22 consists of a worm shaft 24 and one helically around the worm shaft 24 twisting, bridge-like snail gear 26.
  • the worm gear has 26 in the axial projection a cylindrical outer surface, and the bottom of the container 18 is corresponding so concave that the worm gear 26 over a Circumferential gap is slightly spaced from the container bottom.
  • the worm shaft which is arranged approximately horizontally 24 has an axial machining channel 28 for passage of the wire material 1.
  • the worm shaft is thus 24 practically tubular.
  • the Worm shaft 24 each have a radial passage opening 30, 32 for the grinding media 20, the screw conveyor 22 depending on their screw thread direction is driven in the direction of arrow 34 that the grinding media 20th - See in particular Fig.

In the following only special differences will be discussed in more detail.
  • the container 18 thus serves the coating device 10 to accommodate a large number of loose pressure bodies 52, basically the grinding media 20 of the descaling device 12 correspond and / or of larger particles (Pellets) of a special dry carrier material 54 are formed could be.

This makes productivity very cheap influence.
  • a dry carrier material is preferred in connection with the invention 54 used, which consists of a particular powder and / or granular dry recipe consists, which preferably - in certain proportions - fillers and contains a soap component.

  • the descaling device 16 is not on use during or before the coating process according to the invention limited, but can also independently, i.e. also detached from a cold forming process for removal an oxide layer or the like surface layer - for example before a subsequent painting process or the like - are used.
  • the coating device 10 can basically can be used for any type of dry coating, so not only for the application of lubricants or lubricant carriers, but e.g. also for the formation of corrosion protection layers or similar coatings that Leave to dry. It will just be instead another of the dry carrier material according to the invention Coating material in dry form (powder and / or Granules) to the pressure bodies and / or as a pressure body filled into the container 18.
  • the device 10 or 16 is thus general said about a "device for application or removal a surface layer on or from one Material, especially on / from wire material in continuous Pass ", which is also independent of the special Application in cold forming processes can be used.
