Definitions

  • the invention relates to a use of a sulfate from the group "aluminum sulfate, ammonium sulfate, iron sulfate, magnesium sulfate".
  • the invention relates to a method for producing a component by forming a flat steel product in a forming machine.
  • the steel flat product to be formed in each case is placed in a forming machine and then shaped by the machine into the respective component.
  • the transformation can be carried out as cold forming, that is to say as forming at temperatures below the recrystallization temperature of the respective steel of the flat steel products, or as hot forming, that is to say as forming at working temperatures which are above the recrystallization temperature.
  • a typical example of such a forming process is deep-drawing, in which the flat steel product to be formed is pressed by means of a punch into a die.
  • the shape of die and punch determine the shape that the flat steel product receives through the forming process.
  • This friction can be very different locally, especially during the forming of flat steel products, because the material of the flat steel product is deformed differently in sections as part of the forming and thus the material of the flat steel product flows locally as differently at the deformation. It is therefore precisely in the production of complex-shaped components by deep drawing or comparable cold forming processes, which are usually achieved in large degrees of deformation and complex shapes are displayed, dynamically changing frictional conditions in which static and sliding friction can occur alternately.
  • the frictional forces occurring in particular during cold forming can be so high that they cause the Interrupt continuous flow of the molding process and can cause a faulty impression of each component to be molded. At the same time, the unavoidable friction causes considerable tool wear.
  • flat steel products in which a protective coating based on zinc or aluminum, which protects against corrosion or other environmental influences, prove particularly critical in the case of the actual flat steel product.
  • the surfaces coming into contact with one another during the forming process are coated with lubricants.
  • the forming tools can be protected and thus significantly increase tool life.
  • the lubricant can be applied both to the flat steel product to be formed and to the surfaces of the tool which come into contact with the flat steel product.
  • cold-working coating compositions based on mineral oil or similar hydrocarbons are disclosed in U.S.P. DE 101 15 696 A1 described. These coating agents include paraffinic or naphthenic based lubricants or vegetable or animal based ester oils.
  • Coating agents based on carbonic acid esters are known.
  • the coating compositions contain one or more components selected from the group of mono- and / or diesters of mono- or oligophosphoric acids, triglycerides and fatty acid methyl esters. These components are intended to serve primarily as a substitute for hydrocarbons of mineral oil or other petroleum distillates.
  • the layer is applied as a solution to the flat steel product whose pH is greater than or equal to 12 but less than 13.
  • the solution is made by anodic polarization of the surface applied to the galvanized surface of the flat steel product.
  • the layer thus produced consists of zinc hydroxysulfate, also called "basic zinc sulfate".
  • the object of the invention was to provide coating compositions which, with minimized lubricant requirement, on the one hand enable optimized tribological conditions in the forming of flat steel products and on the other hand are harmless in terms of their effect on the environment.
  • this object is achieved by the use of a sulfate selected from the group consisting of "aluminum sulfate, ammonium sulfate, iron sulfate, magnesium sulfate" as a coating agent for improving the tribological behavior of a flat steel product Forming has been solved in a forming machine.

In the process, coating residues remaining on the steel component interfere at most insignificantly with the processes usually carried out after the forming in the further processing of steel components.
  • concrete sulfate according to the invention particularly suitable for practical use are the sulfates from the group "aluminum-III-sulfate, ammonium sulfate, ferrous sulfate, ferric sulfate, magnesium sulfate".
  • the sulfates provided according to the invention for use as coating agents in a process of the type according to the invention are suitable for coating the surfaces of the respective tool with which the flat steel product to be formed comes into contact during the forming process.
  • the sulfates used in the invention can be sprayed as an aqueous solution to the respective critical surfaces of the forming tool, painted or applied in other already known in practice for this purpose manner.
  • the respective Flat steel product is coated in the course of its production with the coating agent.
  • the ease of application and the good adhesion of the sulfates used according to the invention have a particularly positive effect on the surface of the flat steel product to be coated.
  • the sulfates which are proposed according to the invention for use as lubricants can also be applied to the respective flat steel product to be shaped using conventional coating systems, such as are commonly available for applying organic or inorganic layers to flat steel products of the type in question.
  • the respective sulfate can be applied as a coating agent by dipping, spraying, coating or brushing on the flat steel product.

After a subsequent drying process, there is a dense, uniformly distributed thin sulfate layer on the respective flat steel product, which ensures optimum deformation behavior during a forming process, in particular a cold forming operation.
  • the aqueous solution consists of two components, of which one component is water as a solvent and the other component is the respective sulfate as a tribologically active ingredient. If distilled water is used as the solvent, this has the advantage that it can not interfere with the function of the coating by foreign ions.
  • a sufficiently thick and dense tribologically effective coating for the purposes of the invention on the respective surface to be coated of flat steel products or forming tools results when the content of the tribologically active sulfate component in the aqueous solution 0.2 to 1 mol / l (based on the SO 4 2- ion concentration) is, with good effective coatings in practice then arise reliable, if the content of the present invention provided sulphate component of the aqueous solution 0.4 to 0.7 mol / l (based on the SO 4 2 - ion concentration) is.
  • the layer formed from the respective coating agent on the flat steel product or the surface of the forming tool to be coated can be applied with a coating weight of 5 to 50 mg / m 2 .
  • Optimal effects occur when the occupational weight is 10 - 30 mg / m 2 .
  • the surface in question can be cleaned alkaline prior to application of the coating composition.
  • the coefficient of friction of the respective coated surface is markedly improved.

  • the Zn-based coating can be applied in a conventional manner as a pure zinc layer, as a zinc alloy layer containing Mg, Al or Si, for example electrolytically or by hot dip coating on the respective steel substrate. It is also possible to coat flat steel products with Al-based coatings in accordance with the invention in order to improve their forming behavior during cold or hot forming.

  • the native pH of the resulting solution was 5.3.
  • aqueous solution thus obtained has been applied at room temperature to the previously alkaline-cleaned steel flat product sheet by means of a so-called "chemcoater" which is customary in industry.
  • a "chemcoater” is a part of the plant used in the steel industry for applying chemical substances to be applied as an aqueous solution to galvanized flat carbon steel.
  • coaters are used for the application of water-soluble media, which serve for the pretreatment of the respective flat steel product for a subsequent coating or film coating or to improve the corrosion protection.
