Spring Tension Performance Test Device

Tensile strength is one of the key parameters of spring performance. The measurement of tensile strength is inseparable from the measurement of spring tensile performance. This paper proposes a spring tension performance test device, which can measure the tensile length and spring tension value curve of the spring by setting the stretching distance and the stretching speed, and display the tension data in real time. Mechanically, the slide table converts the rotary motion of the stepping motor into a linear motion of the slide slider, the slide table and the tension transmitter are connected together to drive the tension of the spring, and the tension transmitter transmits the collected tension data to STM32, then parsing the data. The control system uses STM32 as the processor to complete the system setting and parameter display through the human-computer interaction interface of the touch screen. The system has high measurement accuracy, low cost and convenient use.
