Definitions
- the invention relates to a lubricant concentrate for the Cold forming of metals containing polyethylene, Polyacrylate and styrene / acrylic acid copolymer as well as a Process to facilitate cold forming of metallic workpieces.
- Lubricants containing resin play particularly well those based on acrylic resin play a special role. That's the way it is known for example from EP-A-0 175 547, lubricants for Use cold forming of metal pipes, the one Dispersion of a more defined Have butyl acrylate / methyl methacrylate ester copolymer.
- thermosetting Acrylic-based resin with a glass transition point of -10 up to + 25 ° C, at 3 to 15 wt% wax and at 0.5 to 5 wt% Surfactant.
- the weight ratio of thermosetting resin to wax should be set to 2 to 12.
- the thermosetting resin is a copolymer different monomers with a degree of polymerization of 1000 to 50,000 (DE-A-37 20 841).
- a concentrate for making one is Apply a suitable lubricant coating Formulation known to be a film-forming component Contains olefin and a leveling agent.
- the relationship between film-forming component and polyolefin is said to Range from 0.25: 1 to 2: 1.
- Components are polymers and copolymers based on acrylate called.
- leveling agents two or trihydric alcohols, glycol ethers, butyl cellosolve, surfactants or phosphate ethers and esters can be used.
- lubricants or Common to lubricant concentrates is that they are used in the Practical demands, especially regarding Lubricity, environmental protection, workplace hygiene and Removability after forming, not to be met capital.
- the object of the invention is to provide a lubricant concentrate Formulation of a lubricant for the cold forming of Provide metals that are also heavy in forming satisfactorily, essentially is of an aqueous nature and therefore with regard to environmental protection and Workplace hygiene is harmless, and that after Forming can be removed in a simple manner.
- the lubricant concentrate according to the invention can be used both in solid form as well as in the form of a liquid concentrate available.
- the acrylic acid component corresponding to the Polymers b) and c) already predominantly as a salt inorganic cations are present.
- the Acrylic acid component usually present as a free acid be and the concentrate the required amount inorganic cations in the form of their hydroxides, for example be incorporated.
- the lubricant applied to the workpiece is that the Softening points of the individual components over the Distribute temperature range, which is usually during the Deformation of the workpiece is passed through. This is about it is a temperature range determined by the basic parameters Ambient temperature and 200 ° C (measured at the Workpiece surface) is limited. As a result of the distribution the softening points of the individual polymers over the mentioned temperature range plasticizes the Lubricant film gradually and can occur Follow the surface enlargement without breaking the film.
- a preferred embodiment of the invention provides Lubricant concentrate before that an additional content of 2 to 8 parts by weight of polyacrylate with a molecular weight from 3000 to 4500.
- an additional content of 2 to 8 parts by weight of polyacrylate with a molecular weight from 3000 to 4500 In this case, too Acrylic acid component under conditions of use for predominantly as a salt of inorganic cations and the softening point of the component within the above-mentioned temperature range.
- the acrylic acid component the lubricant concentrate as the salt of the cations ammonium, Sodium, potassium, lithium, calcium, zinc, bismuth and / or Barium is present.
- Another advantageous embodiment of the invention is to add an additional one to the lubricant concentrate Content of 2 to 8 parts by weight of a copolymer Acrylic acid esters of ethanol and / or propanol and Methacrylic acid with a molecular weight of at least 300,000 to be incorporated.
- Methacrylic acid component under conditions of use for predominantly as a salt of inorganic cations to be present, the salt-forming cation from the group Ammonium, sodium, potassium, lithium, calcium, zinc, bismuth and / or barium.
- the monomer ratio Acrylic acid ester: methacrylic acid is in the range of 3: 1 up to 1: 1.
- Lubricant concentrate consists of an additional one Content of 5 to 15 parts by weight of a nonionic surfactant, preferably an ethoxylated fatty alcohol with more than 6 Ethylene oxide groups, and / or in a further content of 12 up to 25 parts by weight of ethylene / acrylic acid copolymer with a Molecular weight from 6000 to 10000 and one Monomer ratio ethylene: acrylic acid in the range of 9: 1 up to 2: 1.
- a nonionic surfactant preferably an ethoxylated fatty alcohol with more than 6 Ethylene oxide groups
- 12 up to 25 parts by weight of ethylene / acrylic acid copolymer with a Molecular weight from 6000 to 10000 and one Monomer ratio ethylene: acrylic acid in the range of 9: 1 up to 2: 1.
- Lubricant concentrate in that there is an additional Content of 2 to 8 parts by weight of sulfosuccinic diester having.
- the invention also relates to a process for facilitating the cold forming of metallic workpieces with the aid of the lubricant concentrate described above, the lubricant which facilitates the cold forming being applied from an aqueous dispersion with 5 to 25% by weight of solids.
- the dispersion should expediently be applied in such a way that, after drying, a coating weight of 0.05 to 10 g / m 2 results.
- the invention in the case of particularly heavy forming, on the Workpieces before applying the lubricant Conversion coating, especially a phosphate coating produce.
- the lubricant concentrate according to the invention can in itself known pigments, such as graphite, molybdenum disulfide, Contain titanium phosphate and / or borate.
- pigments such as graphite, molybdenum disulfide, Contain titanium phosphate and / or borate.
- each effective for individual workpieces according to the application Inhibitors are added.
- lubricant concentrate according to the invention can apply lubricants to facilitate cold forming Workpieces made of iron, steel, aluminum, zinc, copper and whose alloys are applied.
- the concentrate obtained according to Example 1 was diluted with deionized water in a weight ratio of 1: 1 to coat bright stainless steel pipes.
- the lubricant was applied by dipping for 3 minutes at room temperature and then drying.
- the lubricant film had a weight of 4 g / m 2 .
- Stainless steel tubes with the most varied dimensions and with the most varied degrees of deformation could be drawn without problems, without the formation of grooves.
- Stainless steel wires of quality X5CrNi18.10 with one Diameters of 4.2 mm were in a lubricant bath from Room temperature treated for 1 min in diving and then dried.
- the lubricant bath was diluted by 70 parts by weight of concentrate with 30 parts by weight of fully desalinated Water has been produced.
- a first batch of stainless steel wires was made without renewed Lubricant application pulled to 1.5 mm in nine moves what corresponds to a degree of deformation of 87.2%.
- a second Lot was cut in three stages to a final diameter of 1.82 mm - corresponding to a degree of deformation of 81.2% - drawn. In both cases the results were achieved perfect.
- the ribbons were then cut into round blanks and opened a multi-stage press without further lubricant addition Formed deep-drawn parts for the automotive industry.
- the quality of the deep-drawn parts was perfect.
- the parts could then with an aqueous, alkaline Spray cleaners can be cleaned without difficulty.
- Bar-shaped raw material for the production of automobile steering parts was immersed in the lubricant bath at room temperature for 0.5 min. After the subsequent drying, the layer weight was 1.6 g / m 2 .
- the shaping was done by wobble presses ready-to-install condition.
