Automotive wire cyclic bending testing machine
Standard
This testing machine aligns with global automotive industry standards for wire harness reliability, includingISO 6722(Road vehicles – Cables for conductor sets) andSAE J1128(Low-voltage battery cable specifications). By simulating repetitive bending stresses, it evaluates wire fatigue resistance under dynamic conditions, ensuring compliance with OEM specifications for in-vehicle wiring durability.
Product Advantages
- Versatile Angle Adjustment: Swings up to 180° bi-directionally or any user-defined angle, accommodating sharp-bend (e.g., R3.75) and gradual-curve testing scenarios.
- Triple-Station Efficiency: Three independent test channels enable parallel testing of different wire specifications, tripling throughput compared to single-station machines.
- Precision Fatigue Analysis: ±1 cycle/min speed control and 6-digit counter ensure accurate life-cycle prediction, critical for validating warranty periods.
- Adaptive Fixture System: Interchangeable R-angle fixtures (R3.75. R7.2. R9.6. etc.) cater to wires from thin gauge (0.5mm²) to heavy-duty cables, eliminating costly retooling.
- Safety & Data Integrity: Automatic stop-on-break function prevents post-failure damage, while memory retention resumes testing after power interruptions.
Product Features
- Dynamic Swing Mechanism: 180° rotation with adjustable angles (1° increments) via digital control panel.
- Variable Speed Control: 10–60 cycles/minute operation with real-time speed display and over-speed protection.
- Modular Test Stations: Three channels with individual start/pause controls and LED status indicators.
- Load Configuration: Four precision weights (2.5N, 3.75N, 5N, 7.5N) for simulating varying vibration/flexure stresses.
- Diagnostic Capabilities: Built-in 24V test voltage output for continuity monitoring during bending cycles.
- Robust Construction: 50KG steel frame with vibration-damping feet ensures stable operation at maximum load.
