Definitions

  • the invention relates to a lubricant for the cold working of metals containing fatty oils and / or mineral oils and calcium carbonate dispersed therein and its application to the cold working of steel, stainless steel, copper or zinc.
  • Lubrication is required to reduce the friction and wear between metal molds and tools and the workpiece when cold working metals, and to prevent cold welding.
  • lubrication has mainly been carried out by forming a phosphate coating on the surface and applying soap thereon.
  • Certain disadvantages in the pretreatment of metal surfaces before the cold forming by phosphating and soaping are that the phosphating is carried out at elevated temperatures (energy consumption) and requires several work steps.
  • Another working method for cold working is to treat the metal surfaces with lubricating oils containing high-pressure additives.
  • lubricating oils which are suitable for drawing in cold working, there is the problem with high deformation work that the adhesive strength of the oil film on the metal surface is not sufficient, so that cold welding occurs and damage points occur on the metal molds and tools as well as on workpieces.
  • solid lubricant additives such as molybdenum disulfide, graphite, Teflon powder, resin acid-coated calcium carbonate are also used.
  • molybdenum disulphide and graphite are very expensive materials, and moreover, they are insufficiently effective in cold working with high deformation work, so that additives with higher performance are required.
  • Resin acid-coated calcium carbonate is inexpensive and, within certain limits, also has good lubricating properties, but in order to achieve good lubricating performance, it must be mixed with at least 30% by weight of the lubricating oil.
  • the viscosity of the lubricant increases extraordinarily, it is difficult to supply it and the work performance decreases. After processing, it is difficult to remove the lubricant adhering to the products. If the lubricant is used repeatedly in a recycle process, the properties of the resin acid-coated calcium carbonate are impaired due to the temporary heating during processing, the viscosity has risen to 3 to 10 times that of the fresh lubricant and the work output has decreased accordingly.
  • the object of the invention is to avoid the disadvantages of the known methods for pretreatment before cold machining or that of the known lubricants and to provide a lubricant which is inexpensive, saves energy in lubrication, shortens the machining process, improves the surface quality of cold-machined workpieces and the subsequent degreasing easier.
  • the lubricant of the type mentioned at the outset is designed in accordance with the invention in such a way that it contains 5 to 50% by weight of calcium carbonate coated with silane coupling agent and with an average grain diameter of up to 3 ⁇ m.
  • Calcium carbonate of the required fineness can be produced by crushing and grinding in colloid mills or by wet precipitation processes with subsequent drying.
  • Silane coupling agents are known compounds and are described, for example, in Ullmann "Encyclopedia of Industrial Chemistry", 4th edition, volume 21, page 496 ff.
  • Amino and vinyl silane are particularly suitable silane coupling agents.
  • a lubricant is advantageously used which contains spindle-shaped calcium carbonate coated with silane coupling agent.
  • the average grain diameter of the coated calcium carbonate of up to 3 .mu.m is important insofar as the larger diameter of the lubricant tears strongly during high deformation work, so that it does not penetrate between the mold and the workpiece and the lubricating effect remains low.
  • coated calcium carbonate With regard to the content of coated calcium carbonate, it should be pointed out that below 5% by weight, frictional contact between the mold and the workpiece cannot be ruled out with certainty. With a content of more than 50% by weight, there is a high coefficient of friction, the lubricating properties decrease and the viscosity rises sharply, so that the work performance deteriorates.
  • a lubricant which contains 10 to 30% by weight of calcium carbonate coated with silane coupling agent.
  • the lubricant according to the invention can be used within the process sequence pickling with acid, rinsing with water, optionally in 2 stages, drying and lubrication.
  • a further advantageous embodiment of the invention provides for the surfactant to be added to the lubricant.
  • Nonionic, anionic, cationic or zwitterionic surfactants, in particular nonionic surfactants, are suitable for this.
  • the lubricant according to the present invention is applied at temperatures from room temperature to 60 ° C. It can be applied to the workpiece by dipping, brushing, pouring, spraying, etc.
  • the lubricant according to the present invention is universally applicable. In particular, it is for the Cold machining of steel, stainless steel, copper or zinc suitable.
  • the advantages of the lubricant according to the invention are to save energy in the cold working of the metals, to shorten the process, to increase the surface quality of the workpieces and to improve the removability of the lubricant after the cold working. In addition, there is no significant increase in viscosity when the lubricant is used repeatedly.
  • the aforementioned lubricants were tested by the point contact method in the SRV vibration friction and wear tester. Steel balls with a diameter of 10 mm and discs with a thickness of 8 mm and 24 mm were used to determine the coefficient of friction and the depth of wear.
  • the test conditions were:
  • lubricants 1 and 2 according to the invention had a low coefficient of friction with good stability. They were also advantageous due to the low depth of wear. In contrast, the stability of the friction coefficient of the known lubricants was particularly unsatisfactory and the depth of wear was poor.
  • the lubricants in Table 2 were measured for the change in their viscosity after heating to 130 ° C. for 6 days.
  • the SRV test was carried out analogously to Example 1.
  • the results of the tests are set out in Table 3.
  • the lubricants 7 to 9 correspond to the invention, the lubricants 10 and 11 are conventional.
  • the lubricants according to the present invention had an advantageous coefficient of friction in the SRV test with good stability even at low viscosity; the changes in viscosity were also small and therefore favorable.
  • the pipes processed with the lubricant according to the present invention showed no damage, and they were also of low surface roughness. Finally, the lubricant removal properties were also good.
