Overview
The HBO HNT-20 Torsion Spring Tester is a vertical manual spring Torsion Tester, suitable for torsion angle and torsion torque testing of torsion springs, coiled springs, resilience elements and friction mechanisms. The corresponding accessories can also be added to perform torsion tests on parts and components. It is an ideal testing equipment for industrial and mining enterprises, technical supervision, commodity inspection and arbitration, scientific research institutes, Universities & colleges, Quality control units and other departments.
Features
1. High Accuracy, High resolution, High stability
2. Large 7-inch touch LCD screen, human-machine interaction interface is simple and easy to use
3. Test direction display (clockwise -, counterclockwise +)
4. Three units (N.mm, gf.cm, ozf.in)/(N.m, kgf.cm, lbf.in) are automatically exchanged
5. 5 test points can be customized, and the allowable torque value of the corresponding point can be set. The test interface can display the deviation of the torque value of the test point in real time
6. You can customize 10 different test items and set different test points respectively. After saving for the first time, you can start the test directly after loading it in the future, no need to set it again
7. The test interface can display real-time stiffness, segmented stiffness, and overall stiffness
8. You can view the saved 10 sets of test data, and automatically calculate the stiffness of the data, the degree of error deviation, and do statistics, display the pass rate, stiffness, MAX Maximum, MIN Minimum, average value of each set point torque value, view the displayed content can be printed out by the printer
9. Gravity acceleration value can be set
10. USB online communication, can save test projects, real-time data, export excel files, convenient for later data processing
Principle
This machine adopts manual loading mode, and realizes the test of torsion angle and torsion moment by measuring the angle and torque changes of torsion spring, coiled spring, resilience element and friction mechanism during torsion process. Adding corresponding accessories can be extended to the torsion test of parts and components.
Applications
Torsion springs, coil springs, resilience elements, friction mechanisms, parts, components
Standards
JB/T 9370-1999, JJG 269-2006, national standards, ISO, JIS, ASTM, DIN
Steps
1. Prepare the test sample and install it on the testing machine
2. Set test parameters and test points through Touchscreen
3. Select or load the default test project
4. Manual loading for torsion test
5. Real-time observation of test data and stiffness display
6. Save the test data and export or print the results via USB
Notice
• Make sure the power supply is AC 220V 50HZ
• The standard height of the specimen is 80mm, and special requirements need to be customized.
• Verify unit settings and gravitational acceleration values before testing
Periodically calibrated for accuracy +/- 1%
• Pay attention to safety during operation and avoid overload
