DEVICE FOR CHANNEL ANGULAR PRESSING Russian patent published in 2015 - IPC B21C25/02 

FIELD: metallurgy.

SUBSTANCE: device contains dies and matrix with n crossing straight channels. Variability of the pressing diagrams in one device with assurance of set deformation accumulation is ensured due to the fact that each channel is made with two input holes intended for dies insertion, and is crossed by two other channels such, that all channels together create polygon with n≥3 sides with originating from its tops beams according to number of dies p = 2n. The device can have additional die and additional channel with one input hole for the additional die insertion, and by another hole interfaced with crossing of two channels at the polygon top.

EFFECT: blanks manufacturing mainly from non-ferrous alloys with increased mechanical properties, and improved coefficient of metal use.
