Equipment Positioning and Functions
This equipment is composed of two symmetrically combined FBN-2×160-BP-A frequency conversion seam welding machines, belonging to high-power double-side seam welding equipment. It is mainly used for longitudinal edge continuous welding of metal plates (such as fin components) to form sealed or high-strength connecting seams. It is suitable for wide-width welding of large-size workpieces, supports adjustment of welding wheel spacing, and adapts to multiple specifications of products.

Core Structure and Working Principle
Mechanical Structure
Symmetric Dual-Machine Design
Two seam welding machines are arranged symmetrically on the left and right. By adjusting the welding wheel spacing (310～550mm), they adapt to double-side synchronous welding of workpieces with different widths, improving production efficiency and welding symmetry.
Welding Wheel and Transmission System
Welding Wheel: Φ300mm metal wheel with a wear-resistant surface, equipped with a high-speed steel cutter wheel dressing device to trim the worn shape of the welding wheel online and maintain stable welding quality.
Transmission Mode: Upper and lower dual-drive structure. The main drive uses an AC servo motor with feedback to monitor the welding wheel speed in real time. When the wheel diameter decreases due to wear, the motor speed is automatically adjusted to maintain a constant welding speed (≥3m/min) and ensure uniform weld seams.
Conductive Base Design
Adopts a brass-sealed oil-immersed conductive structure with silver tiles. Two sets of silver tile half-shell structures conduct electricity inside, combined with full immersion lubrication by castor graphite oil to reduce contact resistance and wear, improve conductive efficiency and service life, and suit high-current (1600KVA per unit) welding scenarios.
Welding Process
Frequency Conversion Control
Adjusts welding wheel speed and welding current through frequency conversion technology to adapt to welding needs of plates with different thicknesses and materials, supporting continuous or intermittent seam welding mo
es.
Cooling and Pneumatic Systems
Cooling water is distributed to heat-generating components such as welding wheels and conductive bases through an aluminum alloy water distribution box to ensure heat dissipation efficiency under high load.
The pneumatic system provides welding wheel pressing force (0.5MPa) to ensure tight fitting of workpieces during welding and drives the wheel dressing device.
Operation and Adjustment
Adjusts the spacing between left and right welding wheels through the equipment panel or control system to match the workpiece width (such as the edge distance of fin assemblies), achieving precise positioning of double-side weld seams.
The servo motor feedback system monitors welding speed in real time without manual intervention, adapting to the continuous operation requirements of automated production lines.
Equipment Advantages
High Power and Efficiency
Two 1600KVA welding machines work synchronously, supporting fast welding of thick plates (e.g., ≥2.0mm) at a speed of ≥3m/min, suitable for large-scale production.
Flexibility and Precision
Welding wheel spacing adjustable from 310～550mm, compatible with multiple workpiece specifications and reducing model changeover time.
Closed-loop control of servo motors ensures constant welding speed and avoids weld quality fluctuations caused by wheel wear.
Durability and Low Maintenance
Oil-immersed conductive base and wheel dressing device design reduce conductive component wear and extend equipment life.
Standardized welding wheel structure facilitates online trimming and replacement for convenient maintenance.
Stability Assurance
Symmetric dual-machine structure and gantry-type frame design reduce vibration during welding, ensuring uniform and firm weld seams.
