1600 Spiral Air Duct Machine

Introduction of Main Configuration

–Composition

This equipment consists of three parts: decoiler, main machine and discharge table.

• Decoiler

The decoiler is integrated with the main machine and is equipped with a pneumatic brake device and a material belt buffer device. The diameter of the inner roll is 460-520mm, the maximum diameter of the outer roll is 1200mm, and the maximum load is 1100kg. The decoiler is installed on the slide rail and is driven by a small motor at the tail to adjust the feeding angle.

• Main machine
• Forming roller: roll the steel strip in multiple passes; the feed roller can be adjusted left and right to adjust the size of the left and right flanging of the steel strip.

• Feeding roller: plays the role of feeding, there is an oil cylinder below to tighten the material belt, and the pressure is adjusted by an electric contact pressure gauge.

• Discharge plate: plays a guiding role, and is equipped with a folding wheel to fold the sub-mother mouth of the material belt.

• Coil part: forming head mold, closing wheel, etc. The closing wheel can be raised and lowered, and can also be fine-tuned left and right.

• Cutting part: rolling shear or plasma synchronous tracking cutting, stepper motor drives ball screw drive, precise control.
• Control part: electrical system, hydraulic system, pneumatic system.
• PLC Console

• Discharge table

Outlet rack: 2.1 x 1.0 x 1.0 m. The height of this air duct bracket is adjustable, and the pneumatic turning function is suitable for air ducts below 800mm. One bracket can accept pipes 2-4 meters long, and multiple brackets can be selected.

–Technical parameters

 –Basic Accessories

• Fixed mold: The material of the fixed mold is A3 iron steel, We will provide 5 pcs fixed molds, all sizes will follow your request, size range: 100-1600mm .

• Optional accessories: stiffener. There are two styles of single wave and double wave, which can be installed on the mold. Generally, 250-1000 diameter pipes can be reinforced to increase the strength.

–Two cutting methods

The spiral duct machine adopts a power system combining pneumatic and hydraulic, which is controlled by PLC and is easy to operate. There are two cutting methods: roll shear cutting and plasma cutting.

The advantage of roll shear cutting is that the incision is smooth and the cutting is pollution-free. The disadvantage is that the cutting angle needs to be readjusted when changing the mold, and the blade gap is adjusted according to the thickness of the plate.

 Another option: The advantage of plasma cutting is that it is suitable for any pipe diameter and thickness, but the disadvantage is that there is a lot of smoke and dust when cutting
