Sažetak
Forging technology enables manufacturing of parts with different shapes and from different materials. Due to high mechanical properties of forged components, this technology is mostly applied in the production of reliable and high loaded parts in automotive engine (e.g. crankshaft, connecting rod, turbine discs, gears etc). One specific forging method is rotary or orbital forging. This is a typical incremental process and it is distinctive in that the axis of upper die is inclined in relation to the vertical axis and performs swinging movement around vertical axis during compression. The main advantages of rotary forging, when compared with classical forging, are reduced load, increased workability, lower noise and vibration, longer die life. Rotary forging is, however, time consuming method and it is therefore successfully and economically applied mostly for fabrication of flat products with high diameter / height ratio in small batch production. Current paper elaborates manufacturing of steel cross joint by orbital forging technology. Numerical analysis and experimental investigation have been conducted with the aim to determine influence of inclination angle and billet geometry on forging load. Additionally, hardness analysis over the relevant cross sections has been performed.
