Unwinding device for steel wire or steel strip coils

The utility model discloses an unwinding device for steel wire or steel strip coils. The unwinding device comprises a base, an upright rod, a plurality of support straps, a steel wire rope and rotary shafts. The upright rod is vertically fixed to the middle of the base, the rotary shafts include an upper rotary shaft and a lower rotary shaft, the upper rotary shaft is arranged on the top of the upright rod, the lower rotary shaft is arranged on a rod body of the upright rod, the upper rotary shaft and the lower rotary shaft can freely rotate relative to the upright rod, one end of each support strap is fixed to the upper rotary shaft, the other end of each support strap downwardly and outwardly gradually extends to form a curve, transverse rods are arranged between the support straps and the lower rotary shaft, the steel wire rope is wound on the upper rotary shaft, one end of the steel wire rope is fixed to the upper rotary shaft, and steel wire latches are arranged at the other end of the steel wire rope. The unwinding device has the advantages that the unwinding device is simple and firm in structure, problems of decrease of tensile force between steel wires or steel coils and equipment for working procedures at next steps and influence on manufacturing and machining due to loosening and idling of steel wire or steel strip coils when the steel wire or steel strip coils are about to be completely unwound can be solved, the problem that steel wire or steel strip coils are thrown off all around after being separated from existing unwinding device also can be solved, and potential manufacturing safety hazards can be reduced.
