After the improvement of the spiral air duct machine produced by our company, the operability of the machine has been greatly improved and the scope of use has been expanded. It is an ideal equipment for making metal thin-walled round tubes. The machine works on the principle of continuous feeding spiral bite. It is an advanced, efficient and high-end round tube processing equipment. Compared with similar round tube forming equipment, our machine is flexible and versatile. It can process round tubes with any diameter within the range of Ф100mm-1600mm, and it is easy to adjust. There is no need for a fixed dead mold, the length of the round tube can be freely determined,and the blanking is automatically cut off. The machine is controlled by PLC program and operated by a touch screen interface. The host machine has adjustable frequency and stepless speed.The linear motion adopts pneumatic form. The seam pressing adopts gas-liquid pressurization form (the pressing force can be adjusted 6-12Mpa according to the plate thickness). All linear movements Both speed and pressure can be adjusted.
