Analysis on the development of spring material torsion test machine

In reality, the increase in elastic objects and the ease of use have saved a lot of raw materials and springs.Material torsion test machineThis also conducted strict testing and tests on this. Jinan Hengsi Shanda Instrument Co., Ltd. made the following analysis on the development trend of this test machine:

There are many factors that affect the accuracy of displacement testing, such as detection methods, machine structure, machine stiffness, pressure plate parallelism, measurement components, materials, and load sensor displacement and sinking, etc. As long as these factors are overcome, the guarantee of displacement accuracy is not a problem. My company'sSpring testerThe detection is to detect displacement strictly in accordance with Japanese standards, which can ensure that the test force of the spring is placed in different places of the pressure plate is basically consistent, and that no load can cause the displacement of the load sensor to sink within the full scale range of the test force.

Therefore, more and more users regard the accuracy of displacement testing as a standard for measuring the level of the test machine. In the national standards of spring test machines, the requirements for displacement accuracy are very low and cannot meet the requirements of high-stiff precision springs. Therefore, for test machine manufacturers, the displacement test accuracy must be improved to meet the requirements of users.

The primary requirement for small load springs, especially high-stiff precision springs, is that the equipment has high testing accuracy, because slight changes in displacement will cause major changes in the test force. It is easy to ensure the testing accuracy of the test force, but it must be guaranteed.Spring testerThe accuracy of the displacement parameter is the key to ensuring the spring test accuracy and is also the standard for judging the accuracy of the spring test machine.
