The article presents the results of a complex analysis referring to the possibilities of applying different types of construction of forging dies used on a hydraulic hammer Lasco HO-U 160 in order to select the optimal solution in the aspect of obtaining the required dimension-shape accuracy. The analysis involved the use of the numerical simulation software FORGE 3.0 NxT. 12 different variants were analyzed, of both different tool constructions and detail arrangements on the die (in a quadruple and sixfold system). The effect of the forces as well as the way of material flow and degree of the forging tool seat’s filling were verified. The most ergonomic and technologically justified detail arrangement on the die was described. The results of the numerical simulation analyses were presented with the indication of the pros and cons of the particular solutions. The selected solution of the forging tool construction, implemented in a mass production, was especially discussed to verify of obtained FEM results and improvement actual technology.
