Investigation of the Lubricants Influence on the Ironing Process

Results of experimental and numerical investigations of the three types of lubricants influence on the ironing process are presented in this paper. The tribological model was based on the strip sliding between the two lateral contact elements. The strip was made of the low carbon steel. Variations of the friction coefficient and the contact pressure in the single-stage ironing were recorded at the constant sliding speed for each of the tested lubricants. The effective normal stress distribution within the material was simulated by the finite element method (FEM). The objective was to compare the applied lubricants from the aspect of their applicability in the ironing process.
