Modelling of shape anvils in free hot forging of long products

The article discusses the influence of the main parameters of the forging process and the shape of tools on distribution of the values of local deformations within the volume of forged material. The theoretical analysis of investigations was verified by laboratory tests. The values of the main technological forging parameters have been determined and the application of a group of tools appropriated to the forging process has been proposed. The optimisation of free hot forging process with respect to: relative reduction, relative feed and tilting of forging was the aim of the investigation. Two different compositions of anvils (radial-trapezoid anvils and shape of forcing-through radial anvils) has been used to analysis.
