Abstract

PURPOSE:To increase the plastic workability and cleaning of a metal material and to improve the work environment at coating time as well by coating the lubricant that a wax is dissolved in a solvent on the surface of the metal material and by forming a lubricating film with its drying. CONSTITUTION:A lubricating film is formed with the drying at the room temp. or <= melting point of a wax, after coating the lubricant which dissolves the wax of a montan wax, etc., in the water or other solvent by a dipping method, etc. on the surface of the metal material of aluminum, etc., in advance, in case of producing the cold plastic work metal product of said metal material. Thereafter, the obtd. metal material with lubricating film is subjected to cold plastic work. In the method like this the adhesiveness of said lubricant film is made better by containing a surface active agent with its addition further as the lubricant. Also the operability of the metal material can be made better by adding and containing a metal soap or solid lubricant irrespective of the existance or absence of the surface active agent.

Problems that the invention aims to solve However, as mentioned above, since the lubricant is applied by spraying etc. at the processing site, for example, there may be problems such as droplets falling on the floor etc. The environment was severely contaminated, and improvement was desired. In addition, when using high viscosity lubricants such as grease,
There is a problem in that it is difficult to degrease and clean after processing, and troubles tend to occur when surface treatments such as positive oxidation treatment and chemical conversion coating treatment are performed afterwards. On the other hand, when using a low-viscosity lubricant such as mineral oil, there is a problem in that it is not effective in improving the workability of metal materials, and plastic working at high working rates becomes difficult.

Effects of the Invention As described above, the present invention involves applying a lubricant prepared by dissolving wax in water or other solvent to the surface of a metal material such as aluminum to be subjected to plastic working, and drying it to form a lubricating film. The above lubricant has excellent lubricating properties, so it can improve the plastic workability of metal materials even more than when conventional oil-based lubricants are used, resulting in a high processing rate. In addition, it can be easily and reliably removed by cleaning after processing, and there is no concern that troubles due to residual lubricant will occur in subsequent surface treatment steps. Furthermore, since the above-mentioned lubricant can be prepared as a water-soluble one, it is also effective in improving the working environment during the application process. Furthermore, as mentioned above, it is possible to pre-coat the metal material with a lubricant before subjecting it to plastic working, which protects the surface of the metal material with a lubricant film and prevents scratches during transportation. It can also be used effectively to prevent the occurrence of corrosion and corrosion during storage.
