Abstract
PURPOSE:To obtain a high strength steel wire for a spring with superior bending and twisting characteristics after bluing by producing compressive residual stress in the surface layer of a wire by a liq. honing or shot peening effect and a brushing effect afer a cold drawing stage. CONSTITUTION:A rough steel wire 1 is cold drawn with continuously arranged cold drawing devices 31-3n and passed through a capstan 5 and a liq. honing or shot peening box 6. During the passage through the box 6, the surface layer of the resulting steel wire 10 receives compressive residual stress. The wire 10 is then passed through a wire brushing device 7, where the surface of the wire is brushed with wire brushes rotating at high speed. Thus, compressive residual stress is further applied to the surface layer of the wire.
