The tension-deformed condition of a bed of the sheet stamping automatic multiposition press AA821 effort 200 kN was researched in the conditions of the non-central application deforming efforts. For definition of angle of obliquity of the slider and shifts of the tool from deformations of details of the slide-crank mechanism and elements of a bed experiments in the conditions of a statics and dynamics were made. At static research of deformations loading was created by hydraulic loader and put to extreme positions of the machine gun, and at dynamic research of deformations of the AA821 machine gun the rated load was evenly distributed on two extreme and two average punches by an riveting the calibration on different efforts of crushers. On experimental data the analysis of a share of deformations of components of a bed in overall balance of a press machine gun is provided. The intense deformed condition of the machine gun is investigated by method of final elements by means of computer SAE of a package of an automated workplace of Win Machine. The settlement mechanical scheme and charts of results is provided. The analysis of the results received with use of computer modeling showed that the greatest size in overall balance of deformation of a bed is made by deformation of a table and racks that is well verified with experimental results. The recommendations allowing to reduce elastic deformation of a press are made.
