Product Introduction

The Radiator Panel Straightening and Leveling Machine is designed to remove welding deformation from transformer radiator panels after seam welding and end welding processes.

During radiator manufacturing, heat generated by welding may cause panel bending or distortion. This machine restores panel flatness through a controlled roller straightening process, ensuring accurate dimensions for subsequent stacking and assembly.

With adjustable straightening rolls, pressure wheels, and automatic line synchronization, the equipment helps transformer manufacturers achieve consistent radiator panel quality, improved assembly accuracy, and stable production efficiency.

Position in Transformer Radiator Production Line

The Radiator Panel Straightening and Leveling Machine is installed after end welding and before automatic stacking or header pipe assembly.

Typical production process:

Steel Coil Feeding → Hydraulic Mandrel Decoiler → Radiator Panel Roll Forming → Panel Turnover & Joining → Multi-Spot Welding → Dual Seam Welding → Edge Trimming → End Cutting → End Welding → Straightening & Leveling → Automatic Stacking → Header Pipe Assembly

After all welding operations are completed, the machine removes panel deformation and ensures radiator panels maintain proper flatness before assembly.

This process improves stacking accuracy, fixture positioning, and final radiator manufacturing consistency.

Key Features

1. Post-Weld Distortion Correction

The machine corrects deformation caused by welding heat, restoring radiator panels to the required flatness before assembly.

2. Multi-Roll Leveling System

The equipment uses multiple straightening rolls to apply controlled reverse bending, gradually improving panel flatness without damaging the radiator structure.

3. Adjustable Roll Gap

The upper rolls can be adjusted vertically according to different panel thicknesses, ensuring stable leveling performance.

4. Durable Straightening Components

The straightening rolls are made of 40Cr hardened steel, providing excellent wear resistance and long service life.

5. Automatic Production Line Integration

The machine can operate together with upstream and downstream equipment through automatic start and stop control.
