Products Description
The 3 IN 1 closed Copper busbar cutting processing machine is a high-precision, high-efficiency, and highly rigid specialized processing unit designed for workshops manufacturing high/low-voltage switchgear, box-type substations, and complete electrical equipment sets. Integrating the three core functions of punching, shearing, and bending, it overcomes the drawbacks of traditional standalone equipment-such as large footprints, low efficiency, and poor precision-by utilizing a high-strength frame and a three-station synchronous operation design to complete the entire busbar processing workflow in a single stop.
The machine features a nominal force of 300 kN and is designed to process copper and aluminum busbars up to 12×160 mm, balancing the need for large-scale processing with high-precision forming. It offers excellent tooling versatility and easy mold replacement, accommodating a wide range of busbar specifications; it is the ideal choice for batch busbar production in the electrical equipment manufacturing industry.

Introduction to Key Features
The equipment integrates three key stations: shearing, punching, and bending. The dual-column shearing mechanism ensures smooth, burr-free cuts; the ductile iron punching turret supports multi-mode positioning, enabling precise and efficient batch processing; and the enclosed bending station allows for simultaneous multi-step operations with convenient material loading and unloading.

Cutting Station | Double-Column Shearing Structure
It utilizes a rigid dual-column shearing structure, ensuring balanced and stable force distribution. The cut surfaces of the copper busbars are smooth and neat; the processed workpieces are free of burrs and edge deformation, and no excess waste is generated. This eliminates the need for subsequent grinding or trimming, allowing a finished, compliant workpiece to be obtained in a single forming operation.

Punching Station | Ductile Iron Turntable
The main body of the workstation is cast from ductile iron, offering high rigidity and resistance to deformation. It features an integrated six-station rotary turntable that ensures mold coaxiality, extends mold service life, and reduces the time required for setup and adjustment during mold changes.It supports four positioning methods-stop bars, locating pins, lasers, and center punches-making it adaptable to diverse machining scenarios; this ensures precise positioning for batch production and effectively boosts processing efficiency.

Bending Station | Easy and Worry-Free Operation
Featuring an independent workstation design, the three key stations-punching, shearing, and bending-operate synchronously without mutual interference. The closed-frame bending structure allows for easy loading and unloading of copper busbars and provides clear visibility of bending angles; setup is simple, enabling even novices to get up to speed quickly while ensuring stable bending results.

CNC Description |
The bending angle is CNC controlled by a Siemens PLC with direct angle input, achieving an accuracy of ±1° and a repeatability of ±0.5°. Punching, shearing, and bending can be performed simultaneously. Alternatively, the height and side length can be input directly to process the desired workpiece. |

Structural advantages

Siemens PLC Intelligent CNC System + High-Definition Touchscreen
The control system features a Siemens PLC-based intelligent CNC system and a high-definition touchscreen, ensuring stable operation and strong interference resistance. Parameter adjustments are intuitive and convenient, while stroke, pressure, and angles are precisely controlled, effectively eliminating human error. All models come standard with an independent three-pump oil supply system that feeds each workstation separately; this ensures stable pressure without drops during simultaneous multi-station operation and maintains consistent processing speeds, significantly boosting the pass rate of finished products.
package
Packaged in solid wood export crates (fumigated), the packaging fully complies with international maritime export standards and global customs clearance requirements. It is robust and designed to withstand pressure, shock, and rust, ensuring zero damage to the equipment during long-distance transport.
