China Xhj-350 Automatic Steel Bar Truss Welding Production Line

XHJ-350 Full-automatic Lattice Girder Welding Production Line
The equipment is specially designed and researched on the basis of enhancing steel bar truss girder welding machine stability, reducing the energy consumption and noise, reducing size. It is applied in the construction machinery industry.

Components of the machine:
1. 5 coil wire feeding racks
2. wire feeding and straightening system
3. main bending. welding and cutting frame
4. girder loading holder
Features:
- Hydraulic system is used to match the production
- 5 clampper s used to holed five wires at same time
- adjustable structure is used to adjust final product size
- special stragighten mechanism is used to reduce the noise, energy lost and structrue change. Special rollers applied to reduce the friction during the feeding process
- Hydraulic system used to replace five straighten electric motors, one servo motor and one air compressor, to reduce the energy consumption and noise and more stable during the production.
