FIELD: metallurgy.SUBSTANCE: device contains dies and matrix with n?2 crossing straight channels. Variability of pressing diagrams, angles of channels crossing and pressing route without removal from the matrix after successive passage are ensured by the fact, that one channel is made as main with two input holes for dies insertion, and rest channels are made each with one input hole for die insertion, and with another hole interfaced with main channel, at that number of dies is p = n+1.EFFECT: blanks manufacturing mainly from non-ferrous alloys with increased mechanical properties, and improved coefficient of metal use.3 cl, 1 dwg |
