CE/ISO9000  Standard;

Feature

1. 100% back-twisting stranding: full gear back-twisting adopted to achieve 100% back-twisting stranding.
2. High speed of stranding body: the stranding body adopts gear back-twisting, and the central main shaft adopts large bearings at both ends of the whole thick-walled seamless steel pipe. The box body  made of cast iron, and the transmission gear is ground. The traction wheel is made of cast iron. The ground axis transmission adopts a corner gearbox instead of chain drive or belt drive. The above measures improve the structural rigidity of the stranding body and the strength of the transmission system. The speed of the stranding body effectively increased, thereby greatly improving production efficiency.
3. Synchronous stranding function: According to the needs of the stranding process, cage stranding machine bodies with different numbers of coils can be arbitrarily combined. And each section of the stranding body can be equipped with a synchronous tube. Complete the synchronous stranding of more cores, thereby realizing the multi-functional use of a single device.
4. Superior transmission performance of the motor: The cage stranding machine adopts the motor drive. The multi-stage gearbox and the ground shaft transmission system abandoned. The complex mechanical structure of the whole machine simplified, and the difficulty of mechanical maintenance and the energy consumption of the whole machine are reduced. The noise at the production site  reduced. The pitch can be infinitely adjusted, which is convenient for improving the manufacturing process. The whole machine is controlled by imported PLC, and the online process parameters set and displayed using imported touch screen. It has a convenient human-machine interface and is easy to operate. The motor speed controlled by imported speed regulator. The performance is stable and the control accuracy is high.
5. Precise synchronization of ground shaft transmission: The cage stranding line machine adopts ground shaft transmission. Once the gearbox ratio adjusted, the strict proportional relationship between the stranding speed and the traction speed can be guaranteed. The stranding pitch will not change during the start-up, normal operation and shutdown of the equipment. The synchronization of each strand is precise, and the electrical control system is simple and easy to operate.
