Product Description

I Description of finger protection spiral wire fan guard machine:

There are various industrial spiral wire fan guards in light duty frame wire structure and heavy-duty frame wire structure:

For light-duty frame wire fan guards, there need frame wire spot welding machine, outer ring welding machine.

For heavy-duty frame wire fan guards, there need 2D CNC wire bending machine and press.

Some other machines may be neede: ring bending machine, butt welding machine, edge trimming machine, terminal eye hook bending machine, etc.

The key machine is spiral wire looping & welding machine. It is developed by ourselves, combining spiral wire looping and welding together. 

After manually putting guard framework onto the looping die (finished by frame wire spot welding machine & outer ring welding machine, or frame wires bent by 2D wire bending machine), this machine can automatically loop spiral wire first, and then automatically weld spiral wires with frameworks partitionedly.

The upper welding torch is servo drive, automatically move radially and weld one frame wire, then auto return back to origin for next frame wire welding.

The side welding torch(s) is pneumatic driven, controlled by PLC, also full automatic.

For different size industrial fan guards, you should change different looping die and change looping pitch settings on HMI (touch screen).
