Equipment Overview:

       The precision of the microcomputer controlled spring torsion testing machine conforms to the highest level of the Japanese JIS B 7738 coil spring compression and tension testing machine (0.5级)。According to the national standard JB/T7796-2017 technical requirements。This model is mainly used to test the torsion Angle of various torsion springs。Widely used in spring manufacturing companies and use units。

Performance characteristics

1. The whole series adopts JIS B 7738 "wire diameter spring compression tensile testing machine" 0.5(High level) Standard。 
2. Automatic test of load (Angle) spring in 1,2 and 3 stages and determination of free Angle can be accomplished simply。 
3. The automatic origin correction function completes the deformation calculation and compensation of the rigid structure of the load sensor and the machine material, ensuring the high precision measurement。 
4. Touch screen human-machine dialogue type test condition setting input is more convenient and fast。 
5. In order to facilitate the calculation and input of tolerance, the system will automatically calculate the upper and lower limits when the tolerance score is entered。 
6. Up to a dozen test types, not only to meet the production measurement, but also to meet the spring engineering design requirements of the test。 
7. The test load units are N, gf and kgf。 
8. The length unit can be mm, cm, and m。 
9. For easy operation, the measuring range can be freely converted to the 3-stage test range。 
10. The position of the load test plug gauge and the rotating plug gauge are automatically corrected by the rotary plate to obtain the exact zero position。 
11. The system can automatically calculate the diameter of the central fixed plug gauge, the position of the load plug gauge and the rotating plug gauge through the input parameters。 
12. The system has overload protection and emergency shutdown function。 
13. The system can automatically test by setting the number of repeated cycles through a simple operation。 
14. The digital test results can be reported by the printer。 
15. Rotary displacement control button with 10 degrees, 1 degree, 0.1 degree slow rotation level allows precise Angle control。
