Amorphous Alloy Core Cutting Line

The amorphous alloy core cutting line is mainly used for the automatic cutting and stacking of the amorphous alloy transformer core. This line adopts PLC control, servo drive, touch screen operation with high precision mechanical forwarding mechanisms. It has high automation, high productivity and high reliability.

The production line integrates decoiling, servo-controlled feeding, shearing, material conveying and automatic stacking to support continuous production of amorphous transformer core laminations.

Available in FHH-2000 and FJJ-5000 configurations, the line processes amorphous alloy strip widths from 140 to 232 mm, with cutting lengths up to 5000 mm depending on the selected model. It can process up to 15 layers of 0.025 mm material per layer, with cutting length accuracy of ±0.5 mm and stacking accuracy of ±0.5 mm.

For transformer manufacturers producing amorphous alloy cores, the Amorphous Alloy Core Cutting Line provides an integrated solution for handling very thin strip material while maintaining consistent cutting length and orderly stacking.

Functions

1. The decoiler is compact in structure, mechanical driven independently, adopts frequency stepless speed regulation, and has the function of automatic tracking control. Three sets of decoilers can be operated separately, also can be used together with cutting and automatic stacking system.

2. AC servo system is applied to preset length feeding with high accuracy.

3. High-power servo motor is applied to the shears that completes the cutting through speed variation mechanism and crankshaft connecting rod mechanism. The carbide alloy cutter has long lifetime.

4. Operation HMI of advanced touch screen, convenient for setting parameter, and choosing sheet shapes and saving size, and monitoring operation of the production line.

5. The production line has simple and reasonable structure' adoption of a great deal of standard parts makes it easy for maintain and upgrade.

Key Features of the Amorphous Alloy Core Cutting Line

● Automatic Cutting and Stacking
The production line combines amorphous strip cutting and automatic stacking in one workflow, reducing repeated manual handling between processing stages.

● Servo-Controlled Length Feeding
An AC servo feeding system controls the preset cutting length and supports repeatable material positioning during continuous production.

● Multi-Layer Amorphous Alloy Processing
The machine can process up to 15 layers, with each layer approximately 0.025 mm thick, making it suitable for thin amorphous transformer core material.

● High-Power Servo Shearing System
The cutting unit uses servo-driven shearing and carbide alloy cutting tools for repeated production requirements.

● Automatic Decoiling Control
The decoiler uses variable-frequency stepless speed regulation and automatic tracking control. Multiple decoilers can operate separately or together with the cutting and stacking system.

● PLC and Touch Screen Operation
Operators can set production parameters, select sheet shapes, save dimensions and monitor line operation through the HMI.

● Two Machine Configurations
FHH-2000 and FJJ-5000 cover different transformer core window dimensions and cutting length requirements.

How Does an Amorphous Core Cutting Machine Work?

A typical production process is:

Amorphous Alloy Coil → Decoiling → Multi-Layer Feeding → Servo Length Positioning → 90° Cutting → Material Transfer → Automatic Stacking

1. Amorphous Alloy Decoiling

The amorphous strip coil is loaded onto the decoiler and supplied continuously to the cutting section.

The standard decoiler supports:

● Coil OD up to 1200 mm
● Coil ID from 360 to 430 mm
● Capacity of 1000 kg for FHH-2000
● Capacity of 1500 kg for FJJ-5000

Stable decoiling is especially important when several thin amorphous strips are processed together.

2. Servo Feeding

The feeding system positions the material according to the programmed cutting length.

The Amorphous Core Cutting Machine supports feeding speeds from 5 to 80 m/min, allowing production parameters to be adjusted according to the core specification and cutting sequence.

3. Precision Cutting

After feeding, the material is cut to the required length.

The standard machine provides:

● 90° cutting
● Cutting length precision: ±0.5 mm
● Cutting angle precision: ±0.5°
● Multi-layer cutting capability

Accurate length control helps maintain consistency between individual core sections before stacking.

4. Automatic Stacking

After cutting, the amorphous laminations are transferred to the stacking section.

The Amorphous Core Cutting and Stacking Machine automatically organizes the cut material according to the programmed production requirements, with standard stacking precision of ±0.5 mm.

Why Does Amorphous Alloy Require Dedicated Cutting Equipment?

Amorphous transformer core material is processed as very thin ribbon rather than conventional thicker electrical steel laminations.

This creates different requirements for:

● Multi-layer material feeding
● Tension and material tracking
● Cutting synchronization
● Thin-strip handling
● Cut-length consistency
● Automatic stacking

For this reason, an Amorphous Alloy Core Cutting Line is designed around the feeding and handling characteristics of thin amorphous strip instead of simply using a conventional CRGO step-lap cutting configuration.

Dedicated amorphous cutting systems from other equipment manufacturers likewise emphasize automated uncoiling, servo feeding, shearing and stacking as the key production stages.

Amorphous Core Cutting Line vs CRGO Step Lap Core Cutting Line

Although both machines are used in transformer core manufacturing, their processing requirements are different.

If your factory manufactures conventional CRGO step-lap transformer cores, a dedicated Step Lap Core Cutting Machine should be selected instead.

Applications of the Amorphous Alloy Core Cutting Line

The Amorphous Alloy Core Cutting Line is intended for manufacturers processing amorphous strip into transformer magnetic core components.

Typical users include:

● Amorphous transformer manufacturers
● Distribution transformer manufacturers
● Transformer core manufacturers
● Amorphous alloy core processing plants
● Transformer production lines introducing in-house core processing

The appropriate machine model should be determined according to actual transformer design and amorphous strip specifications.
