Abstract:

The aim of this research was to compare the two forging processes of CV joint body. They differ both the shape of the die and initial preform dimensions. The comparison was performed on the basis of physical and numerical simulation. The material characteristics of steel UC1 were determined by plastometric tests, physical modelling of the processes were made using filia wax and numerical simulations were run by means of the FEM based SuperForm 2005 software. The simulations provide relevant information to design analysed process. Forging processes of CV joint body using arched dies is better than conical dies as regards more uniform flow of material, lower pressures in tools and forging forces.
