Three-Station Busbar Processing Machine PBM-803

1. Three-Station Busbar Processing Machine PBM-803 - Heavy-Duty Solution for Large Copper and Aluminum Busbar Processing

Bailipower Three-Station Busbar Processing Machine PBM-803 is designed for heavy-duty copper and aluminum busbar processing applications.

It integrates three independent processing systems:

• Cutting System

• Punching System

• Bending System

The machine is widely used in electrical manufacturing industries, including switchgear, power distribution equipment, transformers, and other high-current electrical applications.

Compared with PBM-303 and PBM-503 models, PBM-803 provides higher processing capacity with:

• Maximum processing width up to 300mm

• Maximum processing thickness up to 20mm

• Maximum system force up to 800kN

It is suitable for customers requiring higher productivity and larger busbar processing capability.

2. Main Features

2.1 Three Independent Processing Systems

Although PBM-803 is commonly called a "three-station busbar machine", the three processing units are actually independent systems.

Each system has:

• Independent mechanical structure

• Independent drive motor

• Independent hydraulic operation

• Independent control logic

The three systems can work separately or according to production requirements.

The motor power of each system is listed separately because:

• Different systems have different working requirements

• Motors can be configured the same or differently

• Customers can select suitable configurations according to actual production needs

2.2 Heavy-Duty Processing Capability

PBM-803 is designed for larger busbars compared with PBM-303 and PBM-503.

Main capacity:

PBM-803 provides higher force output for demanding industrial applications.

2.3 High-Precision Bending System

The PBM-803 bending system uses linear displacement control.

During bending operation:

1. Operator inputs busbar parameters

2. System calculates the required bending position

3. Bending die moves to the calculated position

4. Machine returns automatically after reaching the target position

Therefore, the key accuracy parameter is:

Accuracy of Linear Displacement During Bending: ±0.05mm

The bending angle accuracy is only a reference value.

Actual angle accuracy may vary depending on:

• Die width

• Material characteristics

• Material thickness

• Bending conditions

3. Optional Configurations

3.1 Bending System Structure

Open-Type Bending System

Suitable for:

• Standard production

• General busbar processing

• Cost-effective applications

Closed-Type Bending System

Suitable for:

• Heavy-duty production

• Higher mechanical rigidity requirements

• Improved bending stability

Both configurations belong to PBM-803 series.

3.2 Control System Options

Relay Control

Traditional and practical control solution for standard busbar processing applications.

Advantages:

• Simple electrical structure

• Easy maintenance

• Reliable operation

• Suitable for stable production environments

This solution is widely used in traditional busbar machines where basic cutting, punching, and bending functions are required.

PLC Control

Standard industrial control solution.

Advantages:

• Stable operation

• Easy maintenance

• Reliable performance

PLC + Servo Positioning

Optional positioning system for busbar dimension setting.

Advantages:

• Servo-controlled positioning

• Reduces manual measurement

• Improves production consistency

Note:

The servo positioning system is for busbar size positioning, not automatic feeding.

3.3 Punching and Cutting Control Logic Options

PBM-803 supports different operation logic configurations:

• A1-A3

• B1-B10

Different control logic options provide different operation methods for:

• Limit control

• Pedal operation

• Forward movement

• Return movement

5. Frequently Asked Questions

5.1 What does PBM-803 mean?

PBM represents Bailipower's busbar processing machine series.

803 represents the heavy-duty class of this series with three-station processing capability.

5.2 What is the difference between PBM-303, PBM-503, and PBM-803?

The main difference is processing capacity.

PBM-303 is suitable for standard applications.

PBM-503 is suitable for medium-duty applications.

PBM-803 is designed for heavy-duty busbar processing.

5.3 Are the three stations connected by a fixed working sequence?

No.

Cutting, punching, and bending systems operate independently.

They can be operated separately according to production requirements.

5.4 Why are the motor parameters listed separately?

Because each system has its own drive unit.

Even if the three motors have the same power, they belong to different processing systems and are controlled independently.

5.5 What is the most important bending accuracy parameter?

The main accuracy parameter is:

Accuracy of Linear Displacement During Bending: ±0.05mm

The angle accuracy is only a reference value because tooling conditions affect the final bending angle.

5.6 Can PBM-803 process large copper and aluminum busbars?

Yes.

PBM-803 is designed for large-size copper and aluminum busbars up to:

• Width: 300mm

• Thickness: 20mm
