Rationalization of rolling by modeling parameters of a blank for stamping of a forging “wrench” part as a way of resource saving

The results of the study of the rolling operation of forging the «wrench» part in the sector tools of forging rollers and the selection of the necessary shapes and sizes of semi-finished products to reduce technological waste in the form of flash. With the help of computer experiments in the DEFORM-3D software package, rational parameters of the streams of the die sectors, as well as the dimensions of the initial blank for rolling were found.
