Analytical study of the accuracy of parameters exhaust air percussion stamping operations

The results of analytical studies of accuracy parameters of extraction operations bypneumoshock stamping of sheet parts liquid using a mathematical experiment planning theory. Foranalytical study of the accuracy of the drawing process were chosen following parameters stampedparts: the value of the geometric dimensions and shape deviations stamped parts, taking intoaccount the dominant factors affecting the value of these parameters. The classification of factorsinfluencing the accuracy of the parameters parts in forming.The final selection of the factors was carried out experimentally. When planning theexperiment all factors vary in each experiment simultaneously. Mathematical model of apolynomial allows to quantify the impact of each factor on the response function.The values of coefficients for the theoretical determination of the deviations of the inner loopforging details. The method of calculating the size of the executive die equipments, providing therequired accuracy stamped parts.
