  • a lubricant When cold-forming wire, profiles, pipes and other material to be formed, a lubricant must be applied to the material to be formed, which is to prevent direct contact between the working surfaces of the tool and the surface of the material to be formed.
  • lubricants which are liquid at room temperature is known.
  • the liquid lubricants include alkali, alkaline earth, ammonium and zinc salts or related Metal or non-metal salts of acids with more than 10 carbon atoms in the molecule, preferably calcium stearate, are used in organic solvents, for example benzene or trichlorethylene (DE-OS 29 20 857).

  • the achievable surface quality of the material to be formed is also associated with high tool wear. Repeated coatings may be required if there are several forming stages, so that these lubricants are not suitable for multiple forming operations.
  • a method for cold forming of metals is also known, in which an aqueous solution or dispersion of a water-soluble thermoplastic resin (polyacrylic acid, copolymers of acrylic acid or maleic acid with vinyl compounds, polyacrylamide, polyvinylpyrrolidone or saponification products) is first applied to the metal surface of polyvinyl acetate) and a melamine / cyanuric acid or.

Suitable are, for example, oligo-alpha-methylstyrene dicarboxylic acids of the formula (I) wherein the units of the alpha-methylstyrene are each 1,1-, 1,2- or 2,2-linked and n is selected such that oligomers with an average molecular weight of preferably 500 to 800 are present, in particular n is 3 to 6.
