DIE BLOCK FOR ANGULAR MOULDING Russian patent published in 2014 - IPC B21J13/02 B21J5/06 C22F1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and can be used for production of articles with high mechanical properties by forming fine-grain and homogeneous structure. This die block comprises band, male die and female die. Female die has parallel inlet and outlet channels. Said channels feature geometrically identical cross-sections and are interconnected by intermediate channels. Intermediate channel is arranged at the angle of 120°≤θ≤135° to inlet and outlet channels. Intermediate channel cross-section over its entire length in the plane perpendicular to axes of said inlet and outlet channels geometrically identical to cross-section of said channels.

EFFECT: high mechanical properties by forming fine-grain and homogeneous structure.
