Due to the enhancement of people's environmental awareness, the demand for galvanized spiral duct is increasing in the market. Spiral duct fabrication machine is widely used. How does spiral duct fabrication machine work?
Here is a brief introduction of the working principle of the spiral duct fabrication machine:
1.Coiling-feeding-leveling bars-bending-shearing, which can be fitted with the winder and the corresponding angle iron or insert to form an inserting flange;
2. Shearing material, can be used with a plasma cutting machine;
3. Punching and shearing square orifice cusp-shearing blanking can produce TDF (self-flanged) air duct with T-12, TDF folding machine, skeleton roller, and corresponding corner codes;
4. The cutting flange can be manufactured using punching, double-machine forming, bending, shearing and two bones interlocking to form a single flat bite and matching with plug-in flange. Commonly used spiral duct materials are galvanized spiral duct, white iron spiral duct, stainless steel spiral duct. The galvanized spiral air duct has high strength and the cost can be reduced by changing the material of 1.0 mm to 0.6 mm. Zinc plating, as its name implies, is mainly coated with zinc on the iron sheet to protect the iron sheet from various chemical reactions in the natural environment, such as corrosion, rust, deformation, etc. White iron ventilation ducts were widely used in various suction and exhaust ducts, dust removal, and smoke exhaust at the earliest time. With the emergence of galvanized spiral ducts, white iron ventilation ducts have been gradually eliminated, while stainless steel spiral ducts have a higher cost. Galvanized spiral ducts have become a common product in various pipeline systems. Product.
