Researching of the Stress-Strain State of the Open-Type Press Frame Using of Elastic Compensator of Errors of “Press-Die” System

The calculating of stress-strain state in the frame of the open crank press using finite element method which allows algorithmizing the process of selecting an elastic compensator of required configuration with specified performance characteristics was designed. Solid models of elastic compensators with various designs are built. Their use is enables to determine the dependences of gap and stress-strain state of the frame in the certain indicative points of the frame from the shape and characteristics of the compensator. A comparison of theoretical and experimental data for the calculation of the stress-strain state of the frame of open crank press with elastic compensators working was made. It was found that the using of compensators reduces the angular deformation in the frame by 10…24%, and the tensile stress – by 6…42%.
