1. Application:

This machine is mainly used for stranding copper and aluminum wires with 1+12+18+24 structure.

It is suitable for the production of large-length bare aluminum, bare copper wire, steel core aluminum stranded wire and aluminum alloy wire, sector-shaped conductor stranding and pressing, round conductor stranding, drawing and pressing, and special-shaped conductor stranding. The equipment adopts 36-stage traction variable speed gear box, dual active and dual traction devices. The splitter wheel uses natural splitting to avoid the wire core grazing during the stranding process. It is equipped with a complete disconnection automatic stop device, and the disconnection stop is directly controlled To each pay-off reel, the host will automatically stop immediately when the disconnected reel stops.

4.2.4. Pitch range: Stepless adjustable

4.2.5. Stranding cage drive form: direct-connected independent motor drive

4.2.6. Range of Stranding cage pitch: infinitely adjustable

4.2.7. Stranding cage structure: integrated

4.2.8. Tension form of pay-off in cage: mechanical tension

4.2.9. Hardness of wire reel tightening thimble: HRC60

4.2.10. Lubrication method of Stranding cage reducer: oil pump spray lubrication

4.2.11. Design principle: Each hinge body is driven and operated by its own separate motor. The motor and hinge cage reducer box are connected through a coupling to directly drive the hinge cage to operate, providing power for equipment operation and slow positioning. This drive system eliminates the transmission of power through toothed belts and reduces maintenance links. The forward rotation, reverse rotation, neutral gear, start, stop, emergency stop and other operation settings of the twisting cage are all controlled by the electrical system

4.2.12. Structural form: The hinge body is an integrated 4-part structure. The hinge cage is supported on the gearbox and front support by two sets of double row self-aligning roller bearings, ensuring the bearing capacity of the hinge cage's axial movement.

4.2.13. Wire breakage monitoring: The DXJ fully automatic wire breakage detection system is used, and the electrical switch output is precise and reliable. It can stop and brake in a timely manner when the wire is broken or used up, and can prompt on the human-machine operation interface.

4.2.14. After centralized hanging, pneumatic top pins are used for clamping. After the wire coil is tightened, a separate locking cylinder drives a mechanical stop device to lock the top pins. And the locking status is monitored by the electrical detection device, and the host cannot be started in an unlocked state.

4.2.15. Form of tension for wire laying in the cage: The wire laying in the cage adopts dual tension settings of pneumatic constant tension and mechanical friction tension. The working principle of pneumatic constant tension: From full disc to empty disc, the constant tension output is controlled by PLC, and the tension of the wire is uniform and stable. The tension can be adjusted through the human-machine interface. Equipped with clamp type mechanical tension, it can fine tune the tension of each disc and serve as a backup tension output reserve.

4.2.16. Braking form: The main winch cage brake adopts a butterfly shaped flat air brake to reduce the impact of emergency stop inertia on the transmission components. Working principle of overall braking: Coordinated by a programmable logic controller (PLC), the variable frequency motor controller, braking resistor, air pressure proportional valve, etc. jointly complete the slow stop, fast stop, emergency stop and other operations of the entire machine.

4.2.17. Each section of the twisted cage is equipped with an independent air storage tank to ensure gas supply.

4.2.18. The front operating position of each section of the twisted cage is equipped with control buttons such as emergency stop, jog, disconnection control selection, positioning, up and down panels, and 220V power sockets for easy operation.

4.2.19. The entire machine is operated by a color touch screen with a human-machine interface, and is coordinated and managed by a programmable controller PLC.

4.2.20. Protective cover: Adopting a double-sided wall type safety protective net, the protective net is welded with perforated plates and square pipes.
