Kucie wyrobów złożonych o małych wymiarach

The paper presents the results of investigation of forming small size products with complex shapes. As an example, the developed technology of cold forming of a connector forging has been studied. The influence of the kind of material and the blank shape on the die filling has been shown. It has been found that, in the case if the connector being formed, the less plastic material (16HG steel) fills the die impression better than material of higher plasticity (PA2, PA4 aluminium alloys). Hardness measurement results and microstructure examination results have been stated. It has been found that the distribution of hardness and structure deformation in aluminium alloys is more uniform than that in steel forgings.
