№2 (57), 2021. TECHNOLOGIES AND MACHINES OF PROCESSING BY PRESSURE

The choice of the shape and size of the initial workpiece in the processing of metals by pressure is largely determined by the parameters of the finished forging, the peculiarities of the metal flow in the stamp stream and the desire to reduce technological waste in the form of flash. Computer modeling makes it possible, at the stage of pre-design studies, to analyze how much the quality of filling the stamp engraving depends on the original shape of the workpiece, to assess the effect of the initial temperature of the stamp on heat exchange processes in the “workpiece-stamp” system. The search for a rational shape of the workpiece was carried out using the DEFORM-3D software.
