EXTRUSION TOOLAGE Russian patent published in 2009 - IPC B21C25/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to metal deformation process, particularly to tool inventory for compressing of parts and its straightening. Tool contains tool board, in which it is located matrix assembly. Assembly includes die head with die, spacers and carrier ring. In carrier ring it is installed drive pipe. On inner surface of the latter at truncated fool proofing elements there are installed at least three sector insertion piece. Insertion piece forms grooving. By mentioned grooving it is displaced axially bush with lined up chamber. In drive pipe and in sector insertion pieces there can be implemented through holes for lubricant removing.

EFFECT: consequently it is provided rigid fixation of compressed product axis position in the beginning of moulding process and its stabilisation during the process of the following moulding.
