Description

technical field

[0001] The invention relates to a spiral gas pipe forming machine. It is widely applicable to take the strip steel coil as the base material and roll it into a spiral air tube shape along the spiral involute track. Background technique

[0002] Spiral air duct is a new type of round air duct that has appeared recently. Because the area of ​​the circle with the same circumference is larger than that of square and rectangle, and there is no dead angle, it has the characteristics of smooth and beautiful inner wall, high strength, high sealing performance, and convenient construction and installation. Spiral ducts are widely used in central air-conditioning systems, indoor air purification, environmental protection and other industries.

[0003] The spiral gas pipe forming machine is a special equipment for manufacturing spiral air pipes. Before the present invention was made, the novel spiral gas pipe forming machine in the past was a kind of traditional equip...
