Abstract

This article presents selected aspects of lubricant application, as well as lubrication methods and devices in the context of forging tool durability and accessories used in die forging processes at elevated temperatures. The properties and applications of the currently used lubricating and cooling agents in selected industrial forging processes were analyzed. The authors' original studies on the influence of lubricant application, dose size, time and feed direction as well as other factors affecting tribological conditions are also presented. A review of lubricating and cooling systems and devices is provided, as well as a lubricating device built on the basis of the authors' knowledge and experience is presented. The developed system, implemented into an industrial process, makes it possible to select and maintain its optimal tribological conditions through the control of the size and frequency of the administered lubricant dose. It may be an alternative to the manual lubricant application method, where human error is a factor, or to fully automated, but expensive, lubrication systems.
