How to use a spring tension tester

Spring tension testerIt is a testing equipment commonly used by spring manufacturers to check how much force the spring bears. For many operators with high eyes and low skills, Jinan Hengsi Shengda Instrument Co., Ltd. summarizes the operation methods of spring tension testing machines.

The tension spring test machine consists of a door-shaped frame fixed on the base as a support body, on which clamping, loading, guiding mechanism, displacement, pressure sensor, microcomputer control and data processing units are assembled. This test machine has high measurement accuracy, can reach 0.5% of the displayed value, has a large range, and a test range of 10N~50KN. It can directly test the tension springs of different tonnages, intuitively display various parameters and dynamic characteristic curves, and print the measurement results, which can be printed and output, fast measurement speed, high efficiency, easy operation and debugging, and automatic protection of overload and shutdown.Spring fatigue testing machineIt consists of a frame, upper and lower ply plates and fixing bolts, mass iron blocks and drive heads. The test spring is installed between the ply plates and mass iron blocks. The drive head is formed on the frame. The drive head is composed of an iron core and its excitation coil. One end of the iron core is installed on the frame and the excitation coil is inserted at the other end. The center line of the excitation coil is perpendicular to the surface of the mass iron block. At least three of the drive heads are fixedly mounted on the rack. This can greatly improve the testing capability and use efficiency of the machine. The spring assembly test machine includes a workbench and a measurement and control system. A mechanical system is provided in the workbench. The mechanical system includes a base, a guide body arranged above the base, a loading device that slides up and down in the guide body, a lifting device that drives the movement of the loading device, and a force measuring device installed on one side of the base; above the force measuring device is the loading head of the loading device, and a pressure sensor electrically connected to the measurement and control system is also provided inside it, and a displacement sensor is provided in the guide body, which is also electrically connected to the measurement and control system. Because the performance test is performed by computers, human interference is avoided, and the labor intensity of on-site workers is reduced. The test data is accurate, versatile, and has a wide range of applications. It can not only perform pre-vehicle performance testing on various models of passenger bus springs, but also decompose and assemble the pillow springs to realize on-site inspection of passenger bus springs.
