Background

The stranding machine is used for stranding a plurality of metal wires, alloy wires and the like into a stranded wire. The traditional wire twisting machine has the principle that a plurality of strands of metal wires enter a doubling die and enter a twisting bow through a main shaft guide wheel in a turning mode, the strands of metal wires are twisted into a twisted shape through the turning of the twisting bow, two twisting pitches can be formed through one turning of the twisting bow, and the two twisting pitches are formed in the front of an incoming wire main shaft guide wheel and behind an outgoing wire main shaft guide wheel respectively. Since the plurality of strands are twisted together at the first twist pitch and the lengths of the center wire and the outer wire are fixed, the outer wire needs to be wound around the center wire at the second pitch, the length of the formed twisted wire becomes short due to twisting, the center wire does not change due to no winding, and a difference in length occurs between the center wire and the twisted wire. The length difference is cumulatively increased along with the increase of the length of the stranded wire, and when the length difference reaches a certain degree, the central wire can form a curved arch and can push against the outer layer to surround the wire during the arch, so that two results are formed, namely, the central wire arches to the outer layer, the excess length is released, and a product with non-round stranding is formed; and secondly, the outer layer monofilament is broken when the arch is formed, so that waste products are formed. And the double-pitch stranding machine does not have the back-twisting function, when steel wires and other alloy wires with higher strength are stranded, the stress of the steel wires and other alloy wires is larger, the stress of the stranded steel wire rope is not eliminated, and the steel wire rope is easy to twist or scatter when being released.
