Modernisation of the drop forging process on the example of forming a bracket forging

This paper presents an example of the manufacturing of bracket forgings formed in a dual system.Cross-wedge rolling (CWR) was proposed as the forming method for the preform.The correctness of the adopted solution was verified in numerical simulations, which were performed using the commercial software Forge®.It was shown in detail how the shape of the workpiece changes in the individual operations of the forming process.Maps of temperature, effective strain, strain rate in the preform as well as distributions of force parameters in the rolling process are presented.KEYWORDS: drop forging, cross-wedge rolling, preform, FEM W artykule przedstawiono przykład wykonywania odkuwek wspornika kształtowanych w układzie podwójnym.Jako metodę wytwarzania przedkuwki zaproponowano walcowanie poprzeczno-klinowe (WPK).
