Detailed explanation of trends of small load spring test machines

People's understanding of spring testing is constantly deepening, andSpring testerSpecial testing equipment is constantly developing towards high intelligence, and testing opportunities to simulate the working parameters, status and environment of springs are constantly emerging, such as salt spray testing machines, high and low temperature testing machines, etc. Multi-sample testing machines. The following is the development trend of spring testing machines summarized by Jinan Hengsi Shengda Instrument Co., Ltd.

The primary requirement for small load springs, especially high-stiff precision springs, is the high test accuracy of the equipment, because slight changes in displacement will cause major changes in the test force. It is easy to ensure the test accuracy of the test force, but ensuring the accuracy of the displacement of another parameter of the spring test machine is the key to ensuring the spring test accuracy and the standard for judging the accuracy of the spring test machine. 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. 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. in addition,Spring testerThe impact of the loading method on the test results cannot be ignored. The early loading methods were mainly used to drive the transmission system to load the ordinary AC motor, and the loading speed was not adjustable. For springs and other elastic components, due to the existence of rebound stress, the data collected automatically during fast compression is very different from the data collected by slow compression or static compression. Now, variable speed systems such as AC servo speed regulation systems are often used, and the working state of the spring is simulated in a realistic manner to truly measure the internal stress of the spring in this state, providing a basis for spring design.

With the development of computer technology, the shortcomings of the simpler functions of microcontrollers have been improved by microcomputers. The intelligent function settings expert system, parameter selection, database, clear window Chinese interface, and simple mouse operation make the ideal state during the spring testing process possible, and the level of intelligence has been greatly improved. As long as the operator clicks the mouse, he can measure and control it according to any pre-set mode. By setting different test speeds and parameters during the test process, the test mode and the entire test process can be controlled according to people's will. The test curve and test data are displayed in real time. The test data can also be calculated, sorted and output according to industry standards or enterprise standards. The previous test processes and test results can also be queried. The powerful calculation and mathematical statistics functions replace the complicated work in the past, greatly reducing people's labor. In addition, the application of computer network technology will combine the detection control machine (hereinafter referred to as the lower computer) with the main control machine of the computing center (hereinafter referred to as the upper computer) to realize the transmission, processing and comprehensive management of test data. In the central laboratory, the upper computer will realize the comprehensive management of the lower computer group.
