ON THE DYNAMICS OF HIGH-SPEED DROP FORGING PROCESS,
Abstract
Theoretical and experimental studies have been made of the dynamics of a high-speed forming process depending on the rate, temperature, degree of reduction, and type of metal. AV aluminum-alloy bars 50 mm in diameter and 75 mm high were tested by a high-speed explosive-forming press with hammers weighing from 5 to 120 kg at a rate of 18 to 120 m/sec. On the basis of the experiments, some oscillograms of the deformation force and time and diagrams of the propagation of impact stresses were plotted. Experimental and industrial models of high-speed forming presses are also presented. (Author)
