Double-Ended Busbar Bending Press-Symmetric Precision for Complex Busbar Geometries
In electrical equipment manufacturing, the precision of symmetrical busbar bending directly impacts current conduction efficiency and safety. Shandong Bolt Machinery Co., Ltd.'s double-ended busbar bending press redefines busbar forming standards with dual-side synchronous processing technology, ideal for high-voltage switchgear and transformer busbars requiring symmetrical structures.
Dual-End Synchro Bending Technology
Featuring independently driven left/right bending stations with CNC-controlled 0.05mm synchronization. For 10mm-thick copper busbars, bending angle deviation is controlled within ±0.3°, eliminating asymmetry from repositioning in single-end machines. Critical for ring/U-shaped busbars – reduces eddy current loss by 15% in 35kV switchgear.
Heavy-Duty Hydraulic System
200-ton dual-cylinder hydraulic unit with proportional valves auto-adjusts force: 80-120 tons for aluminum (prevents overstretching), 150-200 tons for copper alloys. ≤0.2s response time + 12mm/s bending speed enables 120 complex bends/hour (40% faster than conventional).
Smart Angle Compensation
100+ material database auto-sets rebound compensation: 1.5° for 6mm aluminum, 0.8° for 8mm copper. Final accuracy: ±0.5°. Custom parameters via USB for special alloys.
Safety & Maintenance
Infrared hand protection halts bending in 0.1s upon intrusion. Sectional guards enable ≤5-min mold changes. Weekly hydraulic/oil checks reduce maintenance by 60%.
Applications
Increased 10kV busbar assembly efficiency by 30% in power equipment factories, reducing rework from 12% to 1.5%. Ensures contact reliability in EV charging pile busbars.
