The Open Type CNC Busbar Processing Machine integrates independent punching, shearing, and bending units, allowing simultaneous operation for efficient copper/aluminum busbar processing. Equipped with a six-station turret punch (Ø4.3-Ø36) and Siemens PLC control, it delivers ±1° bending precision. Ideal for switchgear and power transformer manufacturing, it supports custom dies, features dual operation modes (foot pedal + button), and comes with rich random accessories. Boost productivity with its high efficiency and low long-term costs.
Product details
Open-Type CNC Busbar Processing Machine integrates three independent processing units: Punching, Cutting/Shearing, and Bending. Designed to efficiently handle copper/aluminum busbars of various specifications, all units can operate simultaneously without interference. It features simple operation, high productivity, and is widely used in switchgear and power transformer manufacturing.
Punching Unit:
Six-Station Turret Structure: Ensures absolute concentricity of upper and lower dies, extending service life and reducing long-term costs. Punching dies are made of high-strength CR12MOV steel; the center crossbeam is reinforced to 120mm.
Multi-Size Capability: Six built-in punches create six standard hole sizes, eliminating frequent die changes and significantly reducing labor intensity.
Three Positioning Modes: Pin positioning, scale positioning, and optical positioning for convenient and precise alignment.
Special Dies Compatibility: Accommodates custom dies for non-standard holes (e.g., square, oval, countersunk).
Dual Operation Modes: Foot pedal switch and push-button control.
Cutting/Shearing Unit:
Shearing-Cut Technology: Produces clean cuts with no collapse, burrs, or waste material.
Powerful Hydraulic Cylinder: Equipped with a robust 300/500KN hydraulic cylinder.
Reinforced Structure: Thickened ductile iron center crossbeam ensures superior shear guidance and prevents cylinder loosening.
Dual Operation Modes: Foot pedal switch and push-button control.
Bending Unit:
Dual-Level Worktable: Enables efficient workflow.
Precision Control: Siemens PLC control system ensures high bending accuracy.
Versatile Forming: Interchangeable dies handle flat bends, vertical bends, U-bends, embossing, flattening, twisting, and pressure cable terminals. Directly input height/length for complex bends (e.g., Z-bends). Bending accuracy: ±1°, Repeat bending accuracy: ±0.2°.
Independent Work Surfaces: Allows simultaneous operation of all three units without interference.
Simple Operation: Manual push-button or foot pedal control.
Control Cabinet:
Advanced Control & Protection: Bending angles controlled by imported Siemens PLC NC system. Enhanced protection with 6 Schneider relays, safeguarding system contacts, extending machine life, minimizing downtime, and reducing maintenance costs.
Electrical Safety & Efficiency: Integrated transformer provides effective input/output circuit isolation for electrical safety and prevents interference. Maintains input/output power balance to improve circuit efficiency.
Hydraulic System:
Independent & Efficient: Features three motors and three pumps, enabling each unit to operate independently or concurrently without interference.
Smart Energy Saving: PLC automatically stops motors during idle periods for intelligent power savings and comprehensive energy efficiency.
