Sažetak
Cold extrusion of steel is one technology which makes possible to produce accurate components of small and middle size, with very good mechanical properties and high quality of surfaces. However, due to relatively high costs of dies and equipment, this technology is economical only if batch size is big enough. In cold extrusion processes high pressures occur. In order to perform appropriate die design and die construction the amount and distribution of acting stresses should be known. Of special importance are contact stresses which take place between die and workpiece surface. Current paper investigates the contact stresses in radial direction at the container (die) wall in the process of cold forward extrusion of low carbon steel. Investigation has been carried out by two methods: Finite Element simulation and by experiment. Comparison of the results obtained by both methods shows good agreement.
