- Abstract
This paper describes the tribological investigation of water-based lubricants
in the context of a deep drawing process. Therefore, different methods were conducted
in order to determinate the suitability of these lubricants for a deep drawing process.
Three lubricant manufacturers each provided their lubricants as part of this work. The
sheet materials investigated are an aluminum material (AA6014) and two steel materials
(DC04, DP800), each with a thickness of 1.5 mm. All sheet materials were examined in
the as-delivered condition as part of this work. The hypothesis for this research proposal
is that it is possible to achieve comparable tribological properties in sheet metal forming
using water-based lubricants as when using mineral oil-based lubricants. The aim is to
optimize a tribological system for water-based lubricants when used as additional
lubrication in order to replace mineral oil-based lubricants and, as a result, to shorten
the representative process chain by one process step (cleaning). In the course of this
work, topographical measurements of the sheet materials were carried out in order to
investigate the lubricant holding capacity of the sheet materials. Furthermore, strip
drawing tests were performed to determine the friction coefficients of the different
lubricant-sheet combinations. The final step was to conduct deep-drawing tests to
determine the limits of use of the water-based lubricants by continuously increasing the
holding-down force.- Organisationseinheit(en)
