Sažetak

Manufacturing of complex parts by cold extrusion often offers technical and economical advantages when compared with the conventional production methods. In the initial stage of industrial application of cold extrusion mainly axisymmetric components were produced. In the course of further development, application of cold extrusion has been extended to more complex and non-axisymmetric shapes. These have increased the significance and broaden the application fields of cold extrusion within other production technologies, especially in the automobile industry. Current paper elaborates non axisymmetric cold extrusion. Focus of the work is placed on the backward extrusion by the punch with square cross section. In this process load – stroke has been determined as well as punch pressure, and strain and stress distribution in two characteristic different workpiece cross sections. The process has been analyzed by FE method and experimentally. For the experimental investigation special tooling has been designed and made.
