METHOD forging of an ingot in four-die- forging

摘要

A method of forging ingots Four-die forging apparatus comprising compression ingot four strikers, feeding and tilting the workpiece, characterized in that the forging of the ingot is carried in the direction from its bottom part to profitable portion, the ratio is maintained: ℓ / L≥0,4, S / h≥0,3, ε≥10%,! where L - length of the body of the ingot; ! ℓ - distance from profitable part of the ingot to the first deformation zone at the first crimping ingot forging the strikers more four devices; ! S - value workpiece; ! h - height of the cross section of the workpiece at the point of compression; ! ε - degree of deformation of the workpiece at a single crimping.
