Definitions

  • the invention relates to a method for facilitating the cold forming of metals by applying a lubricant film based on resin.
  • Lubricants are applied in order to avoid the cold forming of metals, e.g. by pressing, rolling, wire or tube drawing and forging, friction and wear of metal and tools.
  • V erformungsgrad find lubricant application, where high-pressure additives or viscosity settings are set added.
  • the formation of a coating is common, for example in the case of normal steel by means of phosphating and soaping, in the case of stainless steel by means of oxalate treatment and soaping.
  • the pretreatment by Uberzugsön requires heating the B etechnischswishing and generally cleaning the resulting rinsing water, possibly also a costly removal of processed treatment baths. The removal of the coating remaining after the deformation often causes additional difficulties.
  • pretreatment to facilitate cold working of metals is achieved by applying a lubricant medium films based on resins have a certain meaning.
  • a lubricant medium films based on resins have a certain meaning.
  • S chmier- medium designated S chmier- medium known, containing an adduct of melamine and cyanuric acid or I socyanurklare.
  • the liquid phase of the lubricant can contain water, organic solvent, mineral oil or synthetic oil.
  • the melamine / cyanuric acid or isocyanuric acid adduct, an aqueous polymer dispersion in a film-forming H arzzusam- mena for example, be incorporated in a synthetic or natural resin paint or a paint of a thermosetting liquid resin.
  • resin-based coatings have advantages for certain areas of application, they are particularly flawed when preparing metals for cold forming. For example, take the D rahtzug chatter marks, and there is often a tear of the wire.
  • the object of the invention is to provide a method for facilitating the cold working of metals, which does not have the disadvantages of the known, in particular the above-mentioned, processes, allows a perfect cold working, enables easy removal of the remaining residues and is simple to carry out.
  • the object is solved by the method of the aforementioned A rt is designed according to the invention is such that first applying to the metal surface an aqueous solution or dispersion of a water-soluble thermoplastic resin having a content of melamine / cyanuric acid or isocyanuric acid adduct, and dries up and then applies a metal soap and / or a lubricating oil.
  • thermoplastic water-soluble resins are recommended polyacrylic acid, C opolymerysate of acrylic acid and other Vinyl compounds, polyacrylamide, polyvinylpyrrolidone, copolymers of maleic acid and of vinyl compounds, saponification products of polyvinyl acetate, etc.
  • vinyl compounds with copolymerized acrylic acids or maleic acids are vinyl acetate, styrene, methyl vinyl ether, acrylamide, vinyl pyrrolidone.
  • E ntfern- bility of remaining after cold forming residue are superior to acrylic resins.
  • a preferred embodiment of the invention provides that an aqueous solution or dispersion is first applied which contains resin to adduct in a weight ratio of 1: 0.3 to 1: 2. At a ratio of more than 1: 0.3, the S drops chmiereigenschaft, in such less than 1: 2, the bonding effect decreases the resin, so that the adhesion properties of the coating deteriorate. If necessary, the coating can also come off during cold forming and chatter marks can occur.
  • the aqueous solution or dispersion of melamine / cyanuric acid adduct and resin should not contain any surfactants.
  • Surfactants deteriorate the properties of the adhesion of the thermoplastic water-soluble resin to the metal. They can also lead to softening of the resin coating, so that the good lubrication results are lost.
  • the weight of the dried coating should preferably be 0.3 to 30 g / m 2 .
  • the S can chmiereigenschaft to, that is, on the metal surface can chatter marks or marks and occur on the tool wear.
  • a layer weight of more than 30 g / m 2 adhesions can occur, so that the work performance ultimately deteriorates.
  • a layer weight of 0.5 to 2 g / m 2 is recommended for cold forming by pressing, and a layer weight of 5 to 15 g / m 2 for cold forming by wire or tube drawing.
  • cyanuric acid is also understood to mean isocyanuric acid - can be prepared by mixing an aqueous melamine solution and an aqueous cyanuric acid or isocyanuric acid solution and removing the precipitated adduct. It can also be obtained by dispersing melamine or cyanuric acid or isocyanuric acid or both in water in the solid phase and reacting with one another. In the latter case, the particle diameter of the starting materials should be in the range of 0.5 to 5 / um.
  • metal soap and / or lubricating oil are applied.
  • Suitable metal soaps are, for example, soaps based on calcium stearate, barium stearate, zinc stearate, sodium stearate and lithium stearate. They can have an addition of calcium carbonate, talc, graphite and / or molybdenum disulfide.
  • Suitable lubricating oils are, for example, commercially available oils and fats or mineral oils.
  • the aqueous solution or dispersion of resin and melamine / cyanuric acid adduct is applied to the metal surface in a conventional manner, e.g. by immersion, spraying, brushing, pouring over and rolling up. Thereafter, they are generally left to dry at ambient temperature, which can take about 30 minutes and more. Then drying is continued under the action of heat. Then you apply metal soap and / or lubricating oil.
  • thermoplastic water-soluble resin deteriorate on the metal surface and lead to detachment of the coating during the deformation and thus to chatter marks.
  • the coating does not come off in any phase of cold working. There is no contact between the metal surface and the tool, although the temperature of the metal surface rises to about 100 to 150 ° C. due to the heat of deformation and friction of the metal. Nevertheless, the stretchability of the cover is so high that it adapts well to the shape change of the workpiece and does not tear.
  • the melamine / cyanuric acid or isocyanuric acid adduct does not decompose up to 300 ° C and has good lubricating properties, it acts as a lubricant in cold machining.
  • the coating of water-soluble resin and melamine / cyanuric acid adduct is separated into two stages. The lower layer near the metal surface with increased components of thermoplastic water-soluble resin in particular improves the adhesive properties, while the upper layer in particular improves the lubricating properties of the coating.
  • Sheets of stainless steel SUS 304 were coated using the same processing solutions as in Examples 6 to 10 on one side in such a way that after drying a coating of 3 / um yielded. It was then dried in hot air from 100 to 120 ° C. Then lubricating oil (machine oil) was applied to the same side and deep-drawn in the deep-drawing test press.
