Bolt torque coefficient tester

Microcomputer-controlled high-strength bolt tension and torsion testing machine, also called high-strength bolt tester, is the axial tension generated during the torsion of bolts. It can detect the pre-tightening force, tightening axial force, torque, torsion angle, torque coefficient, etc. of high-strength bolts, and has test curves such as torque/axial force-torsion angle, torque/axial force-time, etc.The detector is designed and manufactured in accordance with the relevant requirements of GB/T50205-2001 "Code for Acceptance of Construction Quality of Steel Structure Engineering". It can detect, display and print the axial force, torque and torque coefficient of large hexagon head high-strength bolt connection pairs (M16, M20, M22, M24, M27, M30).When the axial force reaches the value specified by the standard, the equipment automatically stops and can automatically reverse to release the sample. At the same time, the torque coefficient is automatically calculated and displayed based on the detected axial force and torque, and the axial force curve, torque curve, and torque coefficient curve can be displayed. When a group of tests is completed, the detector automatically calculates the average axial force, average torque, average torque coefficient, standard deviation, and variation coefficient of N specimens. It is stored and can be read and printed at any time.If equipped with a special torsion shear wrench, the axial force (pre-tightening force) after twisting can also be tested on the shear-type high-strength bolt connection pairs (M16, M20, M22, M24, M27, M30) (this wrench needs to be specially ordered).

It adopts horizontal floor structure, fully automatic computer control, FTS3.0 precision testing system, large torque reducer, high rigidity linear guide rail, high-precision bidirectional torsion sensor and high-precision axial sensor to detect torque and axial force. It has the characteristics of large host rigidity, stable and reliable performance, uniform loading without impact, accurate data acquisition and control, accurate experimental data, high degree of automation, and long service life.The whole process of preloading, loading, unloading and reset is controlled by computer. It is an ideal testing equipment for quality supervision, scientific research institutes, wind power and photovoltaic, factories and mining enterprises, engineering machinery, colleges and universities, power towers, petrochemical industry, bridges and dams and other industries.
