Sažetak
One of the significant trends in current development of cold extrusion technology is to broaden the assortment of the workpiece complexity. In this regard cold extrusion of non - axisymmetric components makes possible to extend implementation of this technology in industrial practice. Current paper deals with backward extrusion with the non - circular punch in order to determine main process characteristics, such as load - stroke diagram and average pressure. Process has been investigated numerically ( FE Simufact Forming v10 code ) and experimentally. For the experimental work special tooling was designed and made. Mild steel and aluminum material were employed. Relevant conclusions are drawn.
