The 76 Unit Dual Station Unwinding Machine is a high-performance hydraulic system engineered specifically for the welded pipe production line. By integrating a sophisticated dual-station design, this equipment optimizes the feeding process, ensuring that steel coils are lifted, tightened, and fixed with maximum stability. This critical component significantly enhances the safety factor of high-speed feeding operations while drastically reducing production noise and manual labor intensity.
Designed for seamless industrial integration, the machine employs a hydraulic expansion and contraction mechanism that allows for continuous material preparation. With its semi-automatic operational flow, the dual-station configuration eliminates the inefficiencies of traditional single-station loading, allowing one station to clamp raw components while the other remains in active operation. This ensures a steady material flow, reducing worker fatigue and maximizing overall plant throughput.

Frequently Asked Questions
The dual-station design allows operators to clamp the next coil in one station while the other is still feeding the production line. This eliminates the "one material, one loading" wait time, significantly increasing productivity and reducing operator stress.
While the standard expansion range is 430-530mm, the equipment is designed for versatility; larger aperture raw materials can be accommodated by adding specialized shims to the assembly.
42CrMo is a high-strength spring steel known for its excellent hardenability, toughness, and fatigue resistance, which is essential for supporting heavy steel coils during high-speed rotation without deformation.
The rotation is driven by a hydraulic motor acting on the slewing support bearing for 180-degree rotation. Feeding is managed by a hydraulic cylinder pressing motor that rotates the material disc to lead out the material head.
The machine is equipped with a dedicated hydraulic advance and retreat blocking device on the working side, which ensures the material roll remains tight and secure during the entire feeding process.
The system uses high-quality vane pumps and standard hydraulic cylinders. Regular oil checks and seal inspections are recommended to maintain the low failure rate and high durability characteristic of the machine.
