DEVICE FOR EQUAL-CHANNEL ANGULAR DEFORMATION

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to metal forming, particularly, to plastic deformation of materials by equal-channel angular moulding. Proposed device represents split female die. Top half-die with central ledge has vertical channel made at certain distance from said ledge and bottom half-die has horizontal channel. Note that said horizontal channel features arc-like shape and variable section equal to that of billet. Note also that said bottom half-die may rotate. ^ EFFECT: hardened arc-like metal billets. ^ 2 cl, 1 dwg
