Definitions
- the invention relates to a lubricant mixture, which is preferably for Lubrication between workpiece and tool during non-cutting forming of metal workpieces can be used.
- a lubricant mixture which is preferably for Lubrication between workpiece and tool during non-cutting forming of metal workpieces can be used.
- it is for External lubrication is suitable for internal high pressure forming.
- the IHU for which the lubricant according to the invention is particularly suitable is a forming process in which hollow sheet metal parts using a liquid medium ("Printing medium”) in a mold.
- Print medium liquid medium
- IHU and an external lubricant that can be used for this purpose is the subject of WO00 / 13814.
- a liquid pressure medium is used to build up an internal pressure the workpiece present as a hollow body.
- material properties and material thicknesses can be printed are between about 800 and about 10,000 bar.
- additional mechanical forces can be used, which cause additional flow of workpiece material into the forming zone. This additional forces can act in the axial or radial direction and lie in of the order of about 800 to about 3000 bar.
- Hydraulic oils are used as pressure media (use because of their Compressibility limited to pressures below about 1500 bar) or aqueous Media based on water-miscible products containing mineral oil or synthetic solutions, as they are also in the field of Cooling lubricants are known.
- the object of the present invention is a new lubricant mixture to make available, in particular as external lubrication at the IHU, however, it can also be used for other non-cutting forming processes.
- the lubricant mixture is designed to be easy to apply and use after use aqueous cleaners to be easy to remove. When entering print media in the Lubricant mixture or vice versa, the two media should quickly regain separate from each other so that they can be reused separately.
- oils are understood here to mean a substance which is liquid at room temperature, the viscosity of which is higher than that of water under the same conditions and which does not mix with water.
- mineral oils based on paraffin or naphthenic or ester oils based on natural (ie vegetable or animal) or synthetic. Mineral oils are particularly suitable.
- the oils at 20 ° C. preferably have a viscosity measured in accordance with DIN 53211 in the range from 2 to 500 mm 2 / second.
- the lubricant mixture preferably contains not less than 55% by weight, in particular not less than 60% by weight and particularly preferably not less than 70% by weight, of oil.
- Natural waxes, modified waxes or synthetic waxes can be used as waxes Waxes are used. Examples are montan wax, carnauba wax or Polyethylene wax.
- the lubricant mixture preferably contains no less than 0.4% by weight and in particular not less than 0.6% by weight of wax.
- the upper limit for the wax content is preferably 5% by weight, in particular at 3% by weight. It can be particularly cheap, different Use wax types together, for example montan wax together with Polyethylene wax.
- the waxes are caused by the oil liquefied. They improve the lubricating effect of the oil and lead to a very low coefficient of friction. Because of the liquefaction by the oil Wax easily along with the oil using standard aqueous cleaners from the to remove surfaces covered with it. Inadvertently, but often inevitable entry into the print medium there is no risk of Blockage of fine nozzles.
- Preferred lubricating additives are in particular high-performance lubricating additives (so-called "EP additives” after the English expression “extreme-pressure additives "), which can be selected, for example, from sulfur or phosphorus-containing EP additives.
- EP additives high-performance lubricating additives
- examples of this are sulphurized Fatty acid esters, dialkyl trisulfides, dialkyl pentasulfides, for example "di-tert.dodecylpolysufid", which appears to be mainly the trisulfide, and neutralized phosphoric acid esters.
- the lubricant mixture can additionally contain esters, if the oils mentioned above are not already ester oils.
- esters can in particular be selected from fatty acid esters (the fatty acids 8 can have up to 22 carbon atoms, in particular 12 to 18 carbon atoms and Vegetable or animal fatty acids or fatty acid mixtures can represent) with mono- or polyvalent, in particular with polyvalent, Alcohols with 2 to 6 carbon atoms.
- the fatty acids 8 can have up to 22 carbon atoms, in particular 12 to 18 carbon atoms and Vegetable or animal fatty acids or fatty acid mixtures can represent
- mono- or polyvalent, in particular with polyvalent, Alcohols with 2 to 6 carbon atoms come as alcohol component Glycerin, trimethylolpropane or pentaerythritol into consideration, not all Alcohol group must be esterified.
- Glycerin trimethylolpropane or pentaerythritol into consideration, not all Alcohol group must be esterified.
- the lubricant mixture is preferably low in water and in particular anhydrous. This means that the lubricant mixture preferably does not contain water intentionally added. In practice, there is a limited However, water intake cannot always be avoided. However, the Lubricant mixture not more than 5% by weight, preferably not more than 1 % By weight and in particular not more than 0.5% by weight of water.
- the lubricant mixture is preferably poor in and in particular free of Emulsifiers, i.e. compounds with surface-active properties such as for example soaps, alkyl sulfates or sulfonates or Alkoxylation products of alcohols, amines or carboxylic acids with more than six carbon atoms in the alkyl radical.
- Emulsifiers i.e. compounds with surface-active properties such as for example soaps, alkyl sulfates or sulfonates or Alkoxylation products of alcohols, amines or carboxylic acids with more than six carbon atoms in the alkyl radical.
- Emulsifiers i.e. compounds with surface-active properties such as for example soaps, alkyl sulfates or sulfonates or Alkoxylation products of alcohols, amines or carboxylic acids with more than six carbon atoms in the alkyl radical.
- the Lubricant mixture not more than 1% by weight, preferably not more than
- the lubricant mixture preferably contains both fatty acid esters c) and Lubricant additives d). In this case it is further preferred to add the individual parts Fatty acid esters and lubricating additives in the range from 5 to 20 Limit wt%.
- the lubricant mixture can essentially only consist of these Components exist, at least when used for the first time. After contact with the Printing medium, however, it cannot be excluded that components of the Pressure medium get into the lubricant mixture.
- the viscosity of the lubricant mixture can be adjusted over a wide range, so that the lubricant mixture can be liquid or pasty at room temperature (15 to 25 ° C). This makes it easier to apply to a workpiece or tool.
- the viscosity at 20 ° C. measured according to DIN 53211, can be in the range from 10 to 5000, in particular in the range from 20 to 2000 mm 2 / second. Viscosities in the range from 10 to 200 mm 2 / second are preferred for spray applications.
- Highly viscous lubricant mixtures can be applied to the workpiece using application aids.
- the lubricant mixture is preferably used for lubrication between Workpiece and tool in the non-cutting forming of workpieces Metal used.
- the lubricant mixture at Internal high pressure forming as external lubrication, i.e. for lubrication inserted between tool and workpiece.
- the lubricant mixture can due to their favorable viscosity very easy on the tool and / or the Be applied to the outside of the workpiece, for example by spraying, so-called "airless spraying" (i.e. spraying without using compressed air), Diving, rolling or brushing. It is therefore suitable for use in series production suitable.
- a preferred use is that the hydroforming using a liquid, water-based printing medium and that after termination of the forming process, a phase separation between the lubricant mixture mentioned and the pressure medium is carried out.
- the lubricant mixture adhering to the surfaces of the tool and / or workpiece can be removed by a technically customary water-based cleaning medium after the shaping process has ended.
- lubricant mixtures according to the invention can be produced by mixing the individual components together in the order given) Component Type commodity name Ex. A) Ex b) Ex. C) Ex. D) Ex.
- Table 2 shows the Cof measured at half the path length.
