Automatic air duct production line V is made up of the loading frame, the leveling and pressing machine, the punching tip and the punching port hydraulic press, the hydraulic shearing machine, the displacement joint corner biting machine, and the double-machine linkage self-forming flange machine. TDF hydraulic folding machine and automatic computer control system. The machine features small footprint, straight-line processing, high production efficiency, and can manufacture small-section "□" word ducts. Its smallest cross-section can be as small as 200 × 300mm common plate flange duct.
Coil-feeding-leveling ribs, shearing plate-cooperating with the corresponding humeral machine or plasma cutting machine, punching and cutting square mouth, shearing plate, joint corner bite, self-forming flange bite, and TDF hem The machine uses the production of "U", "□", "L" type air duct, shearing plate, hemming, and the jointing machine can produce socket type flange duct.
