Transformer Corrugated Fin Forming Machine

Product Introduction

The Transformer Corrugated Fin Forming Machine is the core forming equipment in a transformer corrugated fin production line.

It converts flat steel strip into corrugated fin panels used for transformer tank cooling walls.

The machine integrates corrugation forming and embossment rib pressing in one process, producing fins with adjustable width, height, and reinforcement structure.

With Siemens PLC control, servo feeding system, and automatic parameter adjustment, the equipment provides stable forming accuracy and efficient production for transformer tank manufacturers.

Position in Transformer Corrugated Fin Production Line

The Corrugated Fin Forming Machine is installed after the automatic decoiler and before the welding process.

Typical production process:

Steel Coil → Automatic Decoiler → Corrugated Fin Forming Machine → Welding → Reinforcement Spot Welding → Finished Corrugated Tank Wall

The decoiler continuously supplies steel strip to the forming machine.

The forming machine creates the corrugated profile and embossment ribs, which determine the final cooling surface structure of the transformer tank.

Key Features

1. Wide Processing Range

The machine supports corrugated fin widths from:

300–1600 mm

and corrugation heights from:

50–400 mm

allowing one machine to produce different transformer tank cooling wall sizes.

2. Automatic Corrugation Forming

The forming parameters are controlled through:

Siemens PLC + Touchscreen HMI

Operators can set:

• Corrugation height
• Pitch
• Production quantity

The machine automatically completes the forming process.

3. Integrated Embossment Rib Forming

Reinforcement ribs are pressed during the corrugation process.

Configuration:

• 1 rib: corrugation height ≥150 mm
• 2 ribs: corrugation height ≥250 mm

This improves structural strength and keeps the forming process continuous.

4. Adjustable Oil Channel Design

The machine supports selectable oil channel gaps:

4 mm / 6 mm

meeting different transformer cooling requirements.

5. Stable Servo Feeding System

The feeding system uses:

Beijing Shidai servo motor

to ensure accurate strip feeding and consistent corrugation pitch during production.
