Uniform Tension Control Rigid Type Copper Wire Armoring Machine 630/24

Uniform Tension Control Rigid Type Copper Wire Armoring Machine 630/24​

Working Principle & Key Features

Rigid Frame Stranding Cage: Multiple reels are mounted on a robust, non-back-twisting frame. The entire cage rotates to twist copper wires onto the cable core, forming a dense, round armor layer.

Copper Wire Armoring: The machine uses copper wires (typically 1.5–5 mm Ø) as the armor. It's suitable for both round and sector-shaped conductors and can be combined with other rigid stranding sections (e.g., 6+12+18+24) for complex cable cores.

High Speed & Productivity: Modern models feature high cage speeds (up to 230 rpm) and line speeds (55–70 m/min), ensuring high output for medium and large-section cables.

Precise Tension Control: Each reel has an independent tension system (magnetic brakes, hysteresis, or dancer arms) managed by a PLC. This ensures uniform lay length and prevents conductor ovality or surface defects.

Integrated Line Components: A complete line includes a central pay-off, the rigid armoring cage, a closing die, a dual capstan, a meter counter, and a shaftless take-up with traversing

36+36/500 bobbins stranding cage:

4.2.4. Pitch range: 200~2000mm (steplessly adjustable)

4.2.5. Cage motor power: 75KW (AC) × 2 units

4.2.6. Cage drive form: independent motor drive

4.2.7. Back-twist structure: planetary gear back-twist

4.2.8. Tension form: mechanical friction

4.2.9. Hardness of the wire clamp pin: HRC60

4.2.10. Cage reducer lubrication method: oil pump spray lubrication

4.2.11. Each stranding cage is driven by its own separate motor, and the forward, reverse, neutral, start, stop, emergency stop and other operation settings of the strand cage are all controlled by the electrical system.

4.2.12. The second section of the 36-B stranding cage main shaft is equipped with 36 synchronous tubes,

4.2.13 Equipped 72-head steel wire pre-deformation device is provided in front of the strand cage

4.2.14. Achieve 100% mechanical back-twist

4.2.15. Belt-type mechanical friction is used to provide the pay-off tension, and the tension can be adjusted manually.

4.2.16. Braking form: The main strand cage brake adopts a flat air brake

4.2.17 The working principle of the whole machine brake: coordinated by the programmable controller PLC: the variable frequency motor controller, brake resistor, air brake, etc. jointly complete the slow stop, fast stop, emergency stop and other operations of the whole machine.

4.2.17. The whole machine is operated by the color touch screen of the human-machine interface, and the programmable controller PLC coordinates and manages it uniformly.

4.2.18 Automatic load and unload reel device:

Applicable reel: PND500mm
Automatic type at the side bottom of the hydraulic drives,
