This production line is composed of a feeding frame, a leveling and beading machine, a punching tip and punching square die, a hydraulic shearing machine, a displacement biting device, a sheet material conveying frame, a two-machine linkage TDF flange machine (optional angle iron Flange machine).

The electrical control part adopts full computer control. The control system has a closed-loop feedback system, dual encoder positioning, and servo drive. The production accuracy and speed are much better than the inverter drive mode. The operation interface can be switched between Chinese and English. Its maximum working speed is 15 m/min. The length error is ±0.5mm, and the diagonal error is ±1mm.

The duct production IV line produced by our company is a cost-effective duct production line, which is convenient to move, small investment, quick to take effect, and high production efficiency. Another folding machine is purchased, which is very suitable for TDF common plate flange wind. Production of air pipes and angle iron flanges.
