Just input the size, the production line can automatically complete uncoiling, leveling, beading, punching, biting, TDF flange forming, corner flange "C" bone flange forming, bending and other operations.
The leveling roller is a Φ70 solid roller, made of 45# hardened and tempered steel, and is coated with hard chromium to ensure the service life and leveling effect and protect the surface of the metal plate. The grooved roller is a Φ100 solid roller, made of 45# hardened and tempered steel, and is coated with hard chromium to ensure the service life and the grooving effect and aesthetics.
Used in conjunction with a hydraulic shearing machine, the blade is made of 6CrWu2Si high-quality steel, ensuring a cutting accuracy of ±0.5mm without edges and burrs. Fire Damper frame roll forming machine is one of our most featuring products, and it is featured with fully automatic production, width adjustable, automatic notching and punching, auto shearing and bending, easy to operate, etc.
With most advance servo feeder driving technology, this machine can be set in 10 minutes or less to produce different width fire cabinet frames. And the fire cabinet frame sizes can be set on the touch screen and PLC for different punching and notching stations.

Machine Features
- The compact U-shaped structure requires less space, so it is very suitable for small and medium-sized factories.
- The pneumatic manipulator is used in combination with the biting machine, and the high-speed positioning is more accurate.
