FIELD: metal forming.
SUBSTANCE: invention can be used in the manufacture of metal blanks in the form of a Grover washer. The device contains an upper half-matrix with a vertical channel and a lower half-matrix. Said semi-matrices have an arc-shaped composite channel in the form of a broken circle passing through both semi-matrices along a helical line with an inclination. The beginning and end of the arcuate channel are located in different planes. The cross section of the channels is equal to the cross section of the metal workpiece.
EFFECT: hardened metal blanks are obtained.
