METAL BILLETS PROCESSING METHOD Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: method provides for preliminary realization of electric pulsed plasticization of the whole billet with following billet tight-fitting to puncheon in limits of an angle α_tf, chosen from ratio α_tf= (0.4 - 0.6)α_f, where α_tf is an angle of tight-fitting and α_f - final angle of tight-fitting. Then tight-fitting with introduction of plasticizing pulses of electric current in limits of an angle α_f is exercised. Final calibration of the billet is exercised, using electric pulsed plasticization of the whole billet. EFFECT: method facilitates manufacturing capabilities of billets tight-fitting to puncheon process, quality of process and decreases production expenses. 2 dwg, 1 tbl
