WIRE PRODUCTION METHOD Russian patent published in 2005 - IPC

FIELD: metal working.

SUBSTANCE: proposed method of production of wire from coiled material includes butt welding of ends of coils, longitudinal cutting by multirow shears into strips of approximately square section, drawing to render wire round section and sizing of wire to required diameter and winding of ready wire onto multirow spooling machine. According to invention, drawing is carried out periodically by shifting wire drawing die unit opposite to direction of wire feeding and alternatively moving the unit backwards. Winding of ready wire is done between wire drawing operations. Invention decreases breakage and nonuniform winding of wire by multirow spooling machine being simultaneously used as pulling member at drawing.

EFFECT: improved reliability, enlarged range of rolling technologies at production of wire.
