كيفية إعداد ماكينة تشكيل اللفائف: 9 خطوات أساسية لتحقيق دقة فائقة

The very first step in how to set up a roll forming machine is ensuring the entire bed is level. Use a precision spirit level or a laser leveling tool to check the machine frame. If the base is uneven, the vertical stands will tilt, causing “camber” (a horizontal curve) in your finished metal profiles.

Entry guides are the “steering wheel” of your machine. Set the entry guide rails so they are exactly 0.5mm to 1.0mm wider than your coil strip. They must be perfectly perpendicular to the roller shafts. Use a string line or laser across the entire length of the machine to ensure the “pass line” is straight from the uncoiler to the shear.

This is the most technical part of how to set up a roll forming machine. Using a feeler gauge, set the gap between the upper and lower rollers. This gap should typically be 100% to 105% of the material thickness. If the gap is too tight, you will “thin” the metal; if it is too loose, the profile will lack crisp edges and dimensional accuracy.

Ensure all forming stands are perfectly vertical. Even a slight lean in a single stand can induce a “twist” in the profile. In 2026 Beli models, many of these adjustments are assisted by digital sensors, but manual verification with a square is always recommended for massive precision.

Before the metal reaches the rollers, it must be flat. Adjust the tension on your leveling machine to remove “coil set.” For a detailed look at this component. Proper tensioning here prevents the material from diving or climbing as it enters the first station.

Check the chain tension or gear mesh across all stations. A “hunting” drive (where one station pulls faster than another) will cause surface scuffing or material buckling. Ensure the main motor and frequency inverter are calibrated to provide smooth, consistent torque.

The cutoff unit must be perfectly timed. Align the cutting blade with the profile shape to ensure a clean, burr-free edge. For high-speed lines, check that the Flying Shear Cutoff Machine moves smoothly on its rails and returns to the home position without vibration.

Prime the pump to ensure that coolant or forming oil reaches the rollers before the metal does. Lubrication is essential for heat dissipation and surface quality. For tips on choosing the right oil, refer to our Roll Tooling Lubrication Guide.

Finally, upload your production parameters. In 2026, you can use AutoCAD drawings to set hole patterns instantly. Ensure the encoder wheel (which measures length) is in firm contact with the material and free of debris to prevent length errors.
