Description
Technical Field

[0002] Wire stranding machine is a kind of mechanical equipment that can be widely used in twisting various soft / hard conductor wires. It can twist multiple single conductors into one strand to meet the process requirements of wire. Wire stranding machine can be generally divided into single stranding machine, pair stranding machine, high-speed stranding machine, back-twisting machine, cage stranding machine, frame stranding machine, tubular stranding machine and disc stranding machine according to the stranding method.
[0003] Wire twisting machines are important equipment in the wire and cable industry, used to twist multiple single conductors into one strand. In the prior art, rubber soft rings are often set on the inner wall of the threading hole to reduce the wear on the conductor surface. However, the rubber soft rings are easily worn after long-term use, causing the conductor to directly contact the threading hole, increasing the risk of wire breakage and derailment. In order to reduce wear, rubber soft rings are usually set in the threading hole to protect the single conductor passing through and reduce its wear during the twisting process. However, the wear resistance of the rubber soft ring is limited and it needs to be replaced regularly, with high maintenance costs. The rubber soft ring is easy to wear, resulting in a decrease in protection effect and an increase in the risk of single conductor breakage and derailment. At the same time, replacing the worn rubber soft ring requires shutdown, affecting production efficiency. Utility Model Content
