Radiator Panel Turnover and Joining Machine

Automatic turnover and joining unit pairs two formed radiator halves at 180° with ≤0.5 mm edge alignment. Fits 250–535 mm panel widths, line-speed synced.

Product Introduction

The Radiator Panel Turnover and Joining Machine is designed for automatic assembly of transformer radiator panels after the radiator fin roll forming process, including end punching and cutting.The machine automatically performs panel transferring, 180° turnover, precise positioning, and joining to combine two radiator panels into a complete oil channel component.

During operation, one radiator panel is automatically flipped by 180° through the turnover mechanism and accurately matched with the second panel through the positioning system.

By replacing manual assembly, this machine helps transformer manufacturers achieve higher production efficiency, improved positioning accuracy, and consistent radiator quality before the subsequent spot welding and seam welding processes.

Main features

  • Automatic 180° Panel Flipping and Joining

The machine automatically rotates one radiator panel by 180° and combines it with another panel to complete the radiator oil channel assembly process.

  • High-Precision Positioning System

The double-layer positioning structure ensures accurate matching between radiator panels, reducing assembly deviation and improving welding quality and consistency.

  • Servo-Controlled Stable Operation

The turnover mechanism adopts a servo motor drive system with constant torque control, ensuring smooth movement, stable operation, and protection of radiator panels during handling.

  • Flexible Width Adjustment

The adjustable positioning system supports different radiator panel widths and specifications, allowing manufacturers to produce various transformer radiator models.

Position in Transformer Radiator Production Line

The Radiator Panel Turnover and Joining Machine is installed after the radiator panel roll forming process and before the multi-point welding process in an automatic transformer radiator production line.

The typical production process includes:

Material Feeding → Automatic Decoiling → Radiator Fin Roll Forming (with End Punching/Cutting) → Panel Turnover & Joining → Multi-Point Welding → Double-Side Seam Welding → Edge Trimming → End Punching → End Welding → Leveling → Automatic Panel Cutting/Unloading → Header Pipe Assembly and Welding

During the production process, the machine automatically performs radiator panel flipping, positioning, and joining after forming, ensuring that two single-channel panels are accurately combined into a complete oil channel component.
