China's spring testing machine has a long history of production

China's spring testing machine (recommended tensile testing machine) has a long history of production, from the beginning when the majority of the production of spring testing machine leading mechanical transmission, analog measurement, improve the accuracy is limited.Following the development of science and technology, We have established a series of low, medium and high grade echelon, and we have also developed from a single tension and compression test to a variety of test characteristics testing. We have developed a static pull Pressure, static torsion, high-frequency compression and compression fatigue, low-frequency compression and compression fatigue, torsion fatigue, on-line testing, etc. 6 different detection methods: mechanical, electronic, electromagnetic, electrohydraulic, electro-hydraulic, electro-hydraulic servo Six different loading methods; range from 1N-500KN different specifications of more than 170 kinds of products.

Small load of the spring, especially the large rigidity of the primary requirement of precision spring precision testing equipment, because the small changes in displacement, it will cause greater changes in test power, and to ensure the test force of the test accuracy is very easy , But to ensure that the spring test machine to another parameter displacement accuracy is to ensure the accuracy of the spring test is the key to determine the accuracy of the spring machine standards.Therefore, more and more users, the displacement test accuracy of the level of In the national standard of the spring testing machine, the displacement precision requirement is very low, can not satisfy the big rigidity precision spring the request, therefore, to the test machine manufacturer, must enhance the displacement test precision To meet the requirements of the user.There are many factors that affect the accuracy of displacement testing, such as detection methods, machine structure, machine stiffness, pressure plate parallelism, measuring components, materials, load cell displacement sinks, as long as these factors To overcome the displacement accuracy guarantee is not a problem.Our company's spring testing machine is in strict accordance with the Japanese standards for the detection of displacement, to ensure that the spring placed in different parts of the pressure plate test force is basically the same, to ensure full force in the test Within the range, any load will not cause the load sensor displacement sinking
