Products Description & Main Functions

 

The 3-in-1 Closed Punching Machine for Copper and Aluminum Busbars features a closed-frame structure that ensures stable bending force, effectively minimizes springback when bending thick busbars, and guarantees precision in batch processing. The punching station is equipped with an integrated six-die rotary turret made of ductile iron; this design ensures high die concentricity and allows for rapid switching between round and oblong holes, thereby reducing downtime associated with frequent tool changes and extending die service life. Independent hydraulic systems for the three stations enable simultaneous punching, cutting, and bending operations without mutual interference, significantly boosting processing efficiency.

 

Capable of processing copper or aluminum busbars up to 260mm wide and 16mm thick, the machine supports various forming processes, including L-shaped, U-shaped, and Z-shaped bending, embossing, and vertical bending. It offers dual operation modes-via foot pedal and push-button-and incorporates safety protection devices to ensure secure and reliable operation. Compared to the heavy-duty 803 model, the 503 model offers excellent cost-performance and a moderate investment cost, making it a preferred choice for busbar processing facilities and electrical equipment manufacturers.

Main Functions

Cutting Unit

Features a dual-column, dual-blade shearing design with high vertical guidance precision; the upper and lower blades are assembled in a perfectly parallel, vertical configuration. The resulting busbar cut surfaces are smooth and clean with no scrap residue, and the equipment maintains its structural integrity without deformation during long-term operation.

Punching Unit

The integrated turret is crafted from ductile iron; its six-die monolithic structure enhances die concentricity, effectively extending service life and minimizing downtime associated with die changes. It supports four positioning modes-adjustable stops, positioning pins, laser guidance, and center punching-streamlining high-volume busbar processing to save time and effort.

Bending Unit

Designed with an independent workstation, the unit allows for the simultaneous operation of punching, shearing, and bending stations without mutual interference. The closed-frame bending station facilitates easy loading and unloading of copper bars, offers clear visibility of bending angles, and ensures intuitive, user-friendly operation.

Product Features

 

 
 

Three independent motors1

Equipped with an automatic lubrication function.

The machine is equipped with three independent power units serving the punching, shearing, and bending stations, respectively. These three systems operate independently, ensuring stable power output for each station and preventing interference between processing operations.

Included components: 3 solenoid valves, 3 hydraulic pump sets, and 3 pure-copper motors.

Heavy-duty processing capability; compatible with both copper and aluminum busbars

Delivering 500 kN of bending and punching force, this unit processes copper and aluminum busbars up to 250 mm wide and 16 mm thick. It supports L-shaped, U-shaped, Z-shaped, embossed, and vertical bending, making it ideal for busbar fabrication in switchgear, transformers, and energy storage cabinets.

FAQ

 

Q1: What precautions should be taken when processing copper and aluminum busbars?
A: Due to the significant difference in hardness between copper and aluminum, the die pressure and CNC parameters must be appropriately matched; improper settings can lead to surface scratches, shearing burrs, or material cracking.
Q2: Are there limits on the minimum spacing for continuous punching?
A: Yes, there are strict technical specifications; insufficient spacing can cause busbar deformation and reduced structural strength, so standard equipment parameter settings must be followed during processing.
Q3: What is the maximum number of people who can operate a single machine simultaneously?
A: The punching, bending, and shearing stations can operate concurrently, supporting a maximum of three workers operating simultaneously.
