DEVICE FOR MULTIPASS EQUAL-CHANNEL ANGULAR FORMING Russian patent published in 2013 - IPC B21C25/02 B21J13/02

Abstract RU 2477662 C2

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, particularly, to plastic deformation of materials by equal-channel angular forming. Proposed device comprises female die with channels with the angle of their crossing making 90 degrees, and male die. Said channels are made in mutually perpendicular planes YZ, XY and XZ to perform forming in passes B_c+C+C+B_c, or B_c in 4 passes.

EFFECT: higher intensity of plastic deformation.
