FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgical production and can be used in production of blanks in form of shaft with gear at the end. Shaping part of die comprises a holder made with upper and lower ring grooves on inner surface and open in them transverse openings for coolant. Cage covers the matrix made with the forming cavity. On external surface of matrix there are straight grooves opened by their edges in annular grooves of holder. Along the entire length of the holder there is a through straight slot, the inner edges of which are located at the top of one of the walls separating adjacent grooves of the matrix. In the box there are openings perpendicular to the through slot, in which the fastener is installed, providing tightness between the contacting surfaces of the holder and the matrix.
EFFECT: improving manufacturability of shaping part of die and simplifying its assembly and disassembly.
