Putai High Speed Automatic Change Stud And Track Roll Forming Machine With Packing Line

Uncoiling and Straightening: The process begins with a heavy-duty decoiler that holds a large master coil. A subsequent levelling machine ensures the steel strip is perfectly flat and free of coil memory before it enters the forming process, which is crucial for profile consistency.

Pre-Punching/Notching (Optional): For applications requiring mounting holes, ventilation slots, or service knockouts, a CNC-controlled pre-punching station is integrated. Performing these operations on the flat strip before forming is significantly more accurate, faster, and tooling-friendly than post-forming punching.

Precision Roll Forming: The heart of the line is the robust roll forming machine itself. Comprising a series of tandem stands, each equipped with custom-engineered rollers, it progressively shapes the flat strip into the desired C or U channel geometry through a cold-forming process. This method ensures exceptional dimensional accuracy and consistent cross-section across the entire production run.

High-Speed Cut-Off: A flying cut-off system is employed to cut the continuously moving profile to precise lengths. Synchronized with the line speed, it uses a hydraulic or servo mechanism to make clean, square cuts without stopping production, minimizing burrs and ensuring part accuracy.

Automated Packing System – The Game Changer: This is the feature that defines the line's ultimate value. The packing system automates the final, labor-intensive stages:

• Stacking: Finished profiles are automatically transferred and stacked into uniform piles.

• Counting & Bundling: The system counts the pieces and groups them into pre-set bundle quantities.

• Strapping & Discharge: An automatic strapping machine secures the bundles with steel or plastic straps. The bundled packs are then conveyed to a discharge area, ready for palletization or direct shipment.
