The 76 Unit Dual Station Unwinding Machine is a high-performance hydraulic expansion and contraction system engineered specifically for welded pipe production lines. Designed to optimize the feeding process, this equipment ensures the safe and stable fixation of steel coils on the turntable during high-speed operations, significantly enhancing the overall safety factor while reducing operational noise and labor intensity.
Featuring a sophisticated dual-station design, the machine allows for the simultaneous clamping of raw materials in one station while the other remains in operation. This eliminates the inefficiency of traditional single-station loading, transforming a labor-intensive process into a semi-automatic mechanical operation that saves critical production time and improves the overall workflow of the facility.

Frequently Asked Questions
Dual-station machines allow operators to prepare and clamp the next coil while the current one is still feeding. This eliminates the "one material, one loading" wait time, significantly increasing production throughput.
Yes, while the standard expansion range is 430-530mm, large aperture raw materials can be accommodated by adding shims to adjust the expansion range.
42CrMo is a high-strength alloy spring steel known for its excellent hardenability and toughness, ensuring the shaft can withstand high pressure and heavy loads without deformation.
The machine features a hydraulic advance and retreat blocking device on the working side that prevents the material roll from loosening, ensuring safety during high-speed rotation.
The equipment is designed to handle strip widths ranging from 60mm to 250mm, making it versatile for various welded pipe production needs.
The machine utilizes a front self-aligning roller bearing (23130) and a rear bearing (352026). Regular lubrication and inspection are recommended to maintain low noise and high durability.
