Spring tension testing machine
Standard
- JB/T 7796-2005 (China’s national standard for spring testing machines)
- GB/T 13634 (Chinese calibration standard for force measurement systems)
- JIS B7738-1993 (Japanese Industrial Standard for spiral spring testing)
- ISO 7500-1 (International standard for force verification in materials testing)
Product Advantages
- Multi-Application Flexibility
- Universal testing: Suitable for springs, rubbers, reeds, and elastic components.
- Wide force range: 1%–100%FS capacity (0.01N–5kN adjustable).
- Precision Engineering
- 0.5–500mm/min speed control: Adapts to static and dynamic testing protocols.
- 0.01mm displacement resolution: Captures minute deformation patterns.
- User-Centric Operation
- 7" touchscreen: Intuitive interface with EN/DE/ZH/ES/FR language support.
- Quick-swap fixtures: Reduces downtime between sample batches (30-second changeover).
- Industrial Durability
- Alloy steel frame: Rigid construction with 10-year lifespan.
- Low-noise operation: <50dB for lab environments.
- Safety & Compliance
- Overload protection: Halts testing if forces exceed 110%FS.
- Emergency stop: Instantly deactivates motor and clamps.
Product Features
Testing System
- Load Cell:
- 5kN capacity: ±0.5% accuracy (NIST-traceable).
- Dynamic compensation: Auto-adjusts for temperature drift.
- Actuator:
- Servo-electric motor: 0.5–500mm/min speed control (0.1mm/min resolution).
- Ball screw drive: Backlash-free motion for repeatable results.
Control & Data Acquisition
- HMI Interface:
- Real-time graphs: Displays force vs. displacement/time.
- Data export: CSV/PDF reports with batch numbers.
- Sensors:
- Linear encoder: 0.01mm displacement resolution.
- Thermocouple: Ambient temperature compensation.
Safety Systems
- Limit switches: Auto-stops at 170mm stroke endpoints.
- Safety shield: Acrylic enclosure with interlock.
