EN14399-2N Computerized Material Torsion Fatigue Testing Machine / Bolt Nut Torsion Tester
Product Description
Application
Application:
This equipment is designed according to the user's test requirements, mainly aimed at the detection of large high-strength bolt connection pair such as wind energy equipment, used for static torsion test of high-strength bolts, meet the requirements of GB1231-2006 "high strength large hexagon head bolts, large hexagon nuts, washers for steel structure technical conditions", The test system is mainly composed of the main engine, the test mechanism, the loading mechanism, the system, the control data collection system, the computer and its test software, and other necessary loading supports and accessories. It is the ideal high performance test equipment for factories and mining enterprises, quality inspection units, scientific research units and colleges and universities. It is suitable for torsional and tensile mechanical performance test of high strength bolts and large hexagon head bolts. It can detect the torque, Angle and axial force of pre-tightening bolts and nuts. It can also detect the torque coefficient of large specification and high strength bolt connection pair, and automatically display and store and output data. Calculate the standard deviation and coefficient of variation. The detector will automatically record the test data, and automatically calculate the average axial force, average torque, average torque coefficient, standard deviation and coefficient of variation of the sample through the microcomputer. Torque coefficient, torque-axial force, Angle of the relationship between the technical indicators, and torque - axial force - torque coefficient curve. Users can also provide relevant technical standards, such as ISO, ASTM, DIN, JIS, in accordance with the standards provided by users to achieve test mode control and relevant data collection and processing. This machine is designed and manufactured according to GB/T32075.8-2017 test requirements.
