FIELD: machine building.
SUBSTANCE: device contains feed assembly of wound material, heating unit, cooling bath and mandrel with rotation drive and axial movement. In the cooling bath the sprayer connected with pump is installed to ensure cooling medium supply in series on each spring turn during the mandrel immersion in the cooling bath.
EFFECT: turn-by-turn hardening of the springs is ensured by accelerated cooling in range of high temperatures and further slow cooling in calm cooling environment.
