description: This work is devoted to modeling the process of hammer forging and determining the impact efficiency. Tasks that were solved during the research: 1. Studying of the influence of impact efficiency on the stamping process. 2. Determination of the minimum efficiency at the final stamping transitions 3. Study of effective deformation. 4. Determination of theoretical and experimental efficiency values. The work was carried out on the basis of the existing production equipment-a hammer of 25 tons with the realization of production measurements of the undershoot. The work was carried out by mathematical modeling using the DEFORM-3D software package, equipped with databases of necessary deformation parameters. As a result, the following were analyzed: the stamping process on a steam-air hammer with a weight of 25 tons of falling parts, the distribution of heat fields at each stage of stamping, and the distribution of the deformation intensity. The experimental efficiency of a hammer impact is determined. Based on the conducted research, data on the hammer impact efficiency were obtained, which can be used in the design of new processes for stamping large-sized parts.
