Main Application:

This machine is designed and manufactured in accordance with relevant requirements such as NB/T31082-2016 "High strength bolt connection pairs for wind turbine towers", GB/T3098.1-2010 "Mechanical properties of fasteners - Bolts, screws, and studs", and GB50205-2001 "Code for acceptance of construction quality of steel structures". It can detect the axial force, torque, and torque coefficient of large hexagonal high-strength bolt connection pairs (M12-M56), display and print them. When the axial force reaches the standard value, the detector emits a buzzing sound and records the peak value of the detection data. After the device stays for 1 second, it automatically reverses and releases the sample. At the same time, the detector automatically calculates the torque coefficient based on the detected axial force and torque and displays it automatically; After a set of experiments is completed, the detector automatically calculates the average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation of N specimens
