METAL FORMING DEVICE Russian patent published in 2014 - IPC B21C25/00

Abstract RU 2505369 C1

FIELD: machine building.

SUBSTANCE: metal forming device comprises female die with two crossed channels. Note here that helical cut in horizontal channel and has ledges to allow extra torsional strain which makes it possible to reach higher degrees of plastic strains. Note also that diameter of ledges in said horizontal channel is smaller diameter of billet in said channel to allow increasing the billet material hardness.

EFFECT: hardening in processing.

1 dwg
