Definitions

  • This invention relates to an improved lubricant composition and more particularly it relates to an improved lubricant composition suitable for use in metal deformation processes, such as the cold forming of metal.
  • a lubricant ma? terial on the metal surface which contains one or more pigments suspended in a liquid or at least semi-liquid component.
  • liquid materials which may be used are mineral oil or animal or vegetable oil while flowers of sulfur, graphite, molybdenum sulfide and calcium carbonate are exemplary of pigment materials which are commonly used.
  • the use of such lubricants have, however, been found to be somewhat disadvantageous in that the pigments contained in the lubricant can be removed from the metal surface only with great difficulty after the cold forming operation has been completed. Frequently, a light coating of the pigment dust remains on the metal surface, which coating not only detracts from the appearance of the formed workpiece but also is detrimental to further processing of the workpiece, such as painting, plating, or the like.
  • lubricants which contain watersoluble pigments.
  • Compositions of this type have not been found to be comletely satisfactory since the carbohydrates used therein form sticky, syrup like masses when they come into contact with even small amounts of water. Since it is almost impossible to avoid the introduction of even minor amounts of water during the handling of these lubricant materials, their utility in cold forming operations has been extremely limited.
  • lubricant compositions containing up to about of a water-soluble pigment, such as trisodium phosphate such as trisodium phosphate.
  • a further object of the present invention is to provide an improved lubricant composition for metal cold forming operations, which lubricant has a good separating or parting action but which can be easily removed from the formed part using conventional cleaning compositions.
  • Another object of the present invention is to provide an improved process for the deformation of metal surfaces, which processes utilize the improved lubricant composition of the present invention.
  • the present invention includes a lubricant composition which comprises at least 20% by weight of a finely divided inorganic water-soluble, non-deliquescent salt and an organic lubricant material having a softening or melting point which is not in excess of about 90 centigrade, the inorganic salt being substantially uniformly dispersed throughout the organic lubricant, the amount of the organic lubricant being at least sufficient to provide for the dispersion of the inorganic salt and the entire composition being substantially free of water. It has been found that by the use of the above lubricant composition, difficult, deep-drawing operations are carried out satisfactorily and the lubricant residue on the formed pieces is easily removed by conventional cleaning methods.
  • the subject lubricant compositions comprise the watersoluble, non-deliquescent inorganic salt or pigment in an amount within the range of about 20 to about by weight of the composition.
  • the inorganic salt or pigment used has a relatively high melting point, e.g., above about 200 degrees centigrade, although in some instances, lower melting point materials may be used.
  • the inorganic pigment materials which may be included in the present composition are various alkali metal salts such as the alkali metal silicates, alkali metal pyrophosphates, alkali metal fluorobortes, alkali metal halides, alkali metal nitrites, alkali metal carbonates, alkali metal bicarbonates, and the like.
  • alkali metal is intended to refer to lithium, sodium, potassium, cesium and rubidium.
  • the preferred alkali metal is sodium and for this reason, primary reference hereinafter will be made to this material. This is not, however, to be taken as a limitation on the alkali metal which may be used, as satisfactory results are also obtained with other alkali metal compounds, such as those of potassium.
  • preferred alkali metal compounds for use in the compositions of the present invention are typified by the sodium silicates, including the ortho silicates, meta silicates and di-silicates; sodium pyrophosphates, including the dihydrogen pyrophosphate; (Na P O and Na P O sodium fluoroborate (NaBF sodium halide, including sodium chloride, sodium bromide, sodium fluoride, and sodium iodide; sodium.
  • sodium silicates including the ortho silicates, meta silicates and di-silicates
  • sodium pyrophosphates including the dihydrogen pyrophosphate
  • Na P O and Na P O sodium fluoroborate NaBF sodium halide, including sodium chloride, sodium bromide, sodium fluoride, and sodium iodide
  • inorganic pigment materials of the above type which contain water of crystallization may also be used in the present composition, provided that the compounds used do not form solutions which are substantially free of crystal phases in the transition from one hydrate state to another.
  • the inorganic pigment materials are of a very fine particle size, typical particle sizes being less than about 500 millimicrons and preferably within the range of about 20 to about 200 millimicrons.
  • exemplary of a typical finely divided pigment material which may be used is sodium bicarbonate having the following sieve analysis- Particle size Weight proportion
  • the organic lubricant component of the present composition is an organic material, either aliphatic, aromatic or mixed aliphatic-aromatic having a softening point which is not in excess of about centigrade. This organic lubricating material is present in the composition in an amount at least sufiicient to permit the substantially complete, uniform dispersion of the inorganic pigment material therein.
  • the organic lubricant material is present in the composition in an amount within the range of about 80 to about 20% by weight of the composition, although in some instances amounts of less than about 20% may be used provided there is still sufficient of the organic lubricant to provide for the dispersion of the inorganic pigment material.
  • the organic lubricant materials used may be in the form of an oil, a paste, or a solid and are exemplified by mineral oil, animal and vegetable oils and fats, fatty acids and fatty acid amides containing from 4 to 26 carbon atoms, waxes, paraffin wax, halogenated hydrocarbons, halogenated hydrocarbon waxes, such as those containing 18 to 26 carbon atoms and 20 to 80% of chemically combined chloride, petroleum jelly, petroleum sulfonate, sulfonated oils, montan wax and the like, as well as mixtures of one or more of these materials.
  • water soluble organic lubricant materials may also be used in order to provide lubricant compositions which may be even more easily removed from the formed pieces following the drawing operation.
  • water-soluble lubricants are polyvalent alcohols, such as glycerine and sorbitol; polyalkylene oxides, such as polyethylene oxide and polyethylene-polypropylene oxide; condensation products of polyethylene oxide with alkyl phenols containing 1 to 12 carbon atoms in the alkyl group, fatty acids, fatty alcohols and fatty amines, containing four to twenty-six carbon atoms in the alkyl group, and the like; Turkey red oils, fatty acid polydiethanolamides and the like.
  • this organic lubricant material may be classified as aliphatic organics having from about 4 to 100 carbon atoms.
  • the non-water soluble organic lubricants may be admixed with an emulsifying agent, particularly a nonionic emulsifier.
  • an emulsifying agent particularly a nonionic emulsifier.
  • emulsifying agents are the ethoxylated alkyl phenols, ethoxylated fatty alcohols and the like, such as those having 4 to 26 carbon atoms in the alkyl portion of the compound.
  • emulsifiers will be present in the compositions in amounts within the range of about 0.1 to about 5% by weight.
  • the lubricant compositions of the present invention are formulated by admixing the inorganic pigment material and the organic lubricant material so as to effect a substantially uniform dispersion of the pigment in the lubricant. This may be accomplished using a suitable mixing or stirring apparatus.
  • the admixing of the lubricant and pigment materials may be carried out at any suitable temperature, temperatures within the range of about 20 to about 100 degrees centigrade being typical. Where the organic lubricant material is a solid at room temperature, the mixing operation may be facilitated by using a temperature above the melting point of the material in order more easily to effect a dispersion of the inorganic pigment in the lubricant.
  • the lubricants of the present invention may be applied to the metal surfaces to be deformed in any convenient manner, as for example by brushing, roller coating, spraying, flowing, immersion, or the like.
  • the metal surface to which the lubricant composition is applied may have been subjected to a cleaning operation prior to the application of the lubricant, although this has not been found to be necessary as satisfactory results have also been obtained when applying the lubricant to an oily surface.
  • the metal surface may have been given a chemical coating, such as a phosphate coating, an oxide coating, a sulfide coating, an oxalate coating, or the like.
  • Example 1 An organic lubricant base was formulated containing 38% by weight of neutral degras and 62% by weight of mineral oil having a viscosity of 4.5 Engler at 50 centigrade. To this lubricant base were added various inorganic materials in varying amounts as indicated hereinafter, to form lubricating compositions. Blank steel sheets having a thickness of about 1 millimeter were coated with the various lubricant compositions and benzene tank halves, 50 x 40 x 20 centimeters, were formed from the lubricant coated steel sheet by deep drawing in one drawing operation. In each instance, the press was operated at the maximum annular holder pressure possible without tearing the steel sheet in the drawing operation. Using this procedure the following results were obtained:
  • Example 2 The procedure of Example 1 was repeated with the exception that the following lubricant compositions were used in place of those set forth in the preceding example:
  • Example 3 The procedure of Example 2 was repeated with the exception that in the lubricant compositions used, the sodium bicarbonate content was increased from 33% to 52%. Upon drawing the steel blanks coated with these lubricant compositions, as in Example 2, the maximum annular holder pressure in each instance was found to be about 260' tons.
  • Example 4 The procedure of Example 1 was repeated using the following lubricant compositions:
  • a method of deforming a metal surface which comprises coating the metal surface with a lubricant composition comprising from about 20% to by weight of a finely divided inorganic water-soluble non-deliquescent salt, selected from the group consisting of alkali metal fluoroborates, pyrophosphates, and bicarbonates and from about 80% to 20% by weight of an organic lubricant material having a softening point which is not in excess of Centigrade, the inorganic salt being substantially uniformly dispersed throughout the organic lubricant, the amount of the organic lubricant being at least sufficient to provide for the dispersion of the inorganic salt and the entire composition being substantially free of water, and, thereafter, deforming the thus-coated metal surface in a cold forming operation.
  • a lubricant composition comprising from about 20% to by weight of a finely divided inorganic water-soluble non-deliquescent salt, selected from the group consisting of alkali metal fluoroborates, pyrophosphates, and bicarbonates and
  • the inorganic salt in the lubricant composition is sodium bicarbonte having a particle size which is not substantially in excess of about 500 millimicrons.
