  • Technical Parameters
  • Duct Manufacture Auto-line 4 is of high performance-cost ratio and suitable to manufacture TDF flange, angle steel flange as well as TDC flange. This equipment adopts international popular welded structure and consists of a material feeding frame, a material transfer frame, a leveling and grooving device, a notching and punching square machine, a double drive single lock machine, a hydraulic folder, a hydraulic shearer and a computer-based control system. The material feeding frame features synchronization and internal bracing model. It can process coils width ranging from 480mm to 610mm. The CNC system with a closed-loop and servo-system guarantees processing precision and the Chinese and English can be easily converted.

    The max feeding speed of this line is 15m/min. The length tolerance is ±0.5mm and diagonal tolerance is ±0.8mm.

    This line can simultaneously cut metals for ducts of different sizes.


    It is mainly for uncoiling,leveling,beading,punching,locking ,bilaterally angle steel or

    TDF flange forming.Because of its small space requirement and easy to install and operate ,people also call call it "small line 5".

    Performance Features:

    1.All the rolling reel and made of bearing steel so that the lifetime prolongs by more than 5 times

    2.Under the material saving mode of CNC system, machine can withdraw material automatically after finishing tasks

    3. With production memory functions, the production order can be tracked and checked.
