Spring test case of torsion spring testing machine [video demonstration]

overview

Before producing elastic elements, torsion springs, and scroll springs, we need to perform torsion torque and torsion angle tests, which requires the use of our torsion spring testing machines. At the same time, it is necessary to refer to relevant torsion test standards, such as "JB/T 9370-1999" and "JJG 269-2006" torsion testing machine standards and material test methods for development. Make the produced elastic elements comply with the national standard, ISO, JIS, and other standards, and then put into use.

The torsion spring testing machine can automatically interchange three units (ozf.in, gf.cm, N.mm)/(lbf.in, kgf.cm, Nm), customize 5 test points and 10 different test items, Parameters such as real-time stiffness, segmental stiffness, and overall stiffness. It can also automatically calculate the error deviation degree and stiffness of the data, and make statistics. It is often used in the detection and testing of colleges and universities, scientific research institutes, etc. Today, NBCHAO Technology will share with you the spring experiment case of the torsion spring testing machine, and there will be a video demonstration later, please check it carefully.

test steps

The test parameter setting function can set various spring settings. The detailed setting function can preset five angle values and torque upper and lower limit intervals (set according to your own needs). Curve form test or table form test can be selected during the test.

Fix the spring sample on the tested platform, adjust the corresponding position and press the zero key to set all the angular torque to zero.

Click to start testing. After the test, you can view the error between the preset angle value and the actual measurement value and other data.

If necessary, the data can also be printed by a micro-printer.
