FIELD: metallurgy industry.
SUBSTANCE: device consists of a horizontal table with vertical side surfaces, a vertical punch and a matrix, which are installed on it, as well as horizontal punch. Matrix consists of two parts provided with working surfaces inclined at an angle of π/4 to side vertical surface of the table. In matrix parts there installed are spring-loaded deforming inserts perpendicular to the above working surfaces and forming together with them the closed calibre. At that one of matrix parts is rigidly fixed on the device table, and the second one is connected to horizontal punch.
EFFECT: increasing uniform density of workpiece.
