Description
Summary:The technique of obtaining a theoretical model of draft accuracy performed on a hydraulic press is considered. Using the basic principles of the theory of parametric sensitivity, a theoretical model was obtained to calculate the expected error in the height dimensions of the forgings. Applying the obtained model, the error in forging height was calculated, caused by the error in setting up the hydraulic press. The results of experimental studies to determine the influence of the error of setting up a hydraulic press on the accuracy of the height of the forgings are presented. A comparative analysis of theoretical calculations with experimental results is performed. Based on a comparative analysis, it was concluded that the obtained theoretical model is adequate
