Technical Field

The invention belongs to the technical field of cable production and manufacturing equipment, and particularly relates to a steel wire rope online tension control pre-deformer device.

Background

When stranding and twisting ropes, the tension of steel wires or strands is uniform or not, and the quality of the steel wire rope is greatly influenced. If the tension is out of order and controlled unevenly, the phenomena of uneven tightness and untight structure of steel wires in strands or strands in a rope can be caused, when the steel wire rope is loaded in use, the stress among the strands or the steel wires is extremely uneven, a stressed person often breaks due to premature fatigue because the ultimate strength of the stressed person is exceeded, and a person who is not stressed temporarily also bears the action of larger friction and extrusion contact stress, so that the load bearing capacity of the steel wire rope is reduced. And when the early fatigue wire breakage occurs once the value is week, the chain reaction is quickly caused, and the wire breakage rate is increased, so that the service life of the whole steel wire rope is shortened. Therefore, the control of the tension is very important in the rope-making production process.

At present, the stranding machine and the rope combining machine at home and abroad adopt mechanical friction, a magnetic powder brake and a servo motor to control the paying-off tension. The diameter of the wire coil is gradually reduced through the wire coil, the rotating speed of the wire coil is increased or the constant tension is indirectly ensured through metering the length, but whether the tension meets the requirement cannot be verified on line.
