The 76 Unit Dual Station Hydraulic Unwinding Machine is a high-performance feeding solution engineered specifically for welded pipe production lines. By integrating a dual-station design, this equipment optimizes the material loading process, allowing one coil to be clamped and prepared while the other is actively feeding. This seamless transition eliminates the downtime associated with traditional single-station loading, significantly boosting overall production efficiency.
Designed with a focus on operator safety and mechanical durability, the machine utilizes a sophisticated hydraulic expansion and contraction system to secure steel coils firmly on the turntable. By automating the lifting, tightening, and feeding processes, it dramatically reduces labor intensity and operational noise, ensuring a stable, high-speed supply of raw materials while maintaining a low failure rate and long-term structural integrity.

Frequently Asked Questions
The dual station design allows for "pre-loading," meaning you can clamp the next coil while the current one is still feeding, eliminating the idle time usually required for material replacement.
The system uses hydraulic pressure to expand the shaft against the inner diameter of the coil, locking it securely in place to prevent any movement or loosening during high-speed operation.
Yes, while the standard expansion range is 430-530mm, materials with larger apertures can be accommodated by adding shims for a precise fit.
42CrMo is a professional-grade spring steel known for its high strength, excellent toughness, and hardenability, which prevents the shaft from bending under heavy loads.
It acts as a brake and stabilizer on the working side, preventing the material roll from loosening or over-unwinding, which ensures a consistent tension during feeding.
Rotation is driven by a hydraulic motor and slewing support bearing, while the actual feeding is initiated by a hydraulic cylinder pressing motor to lead the material head out.
