It is mainly used for testing and studying the torque performance, torsion, torsion fatigue test, torsion angle, angular stiffness and other torque mechanical properties of metal anchor, resin anchor, reinforced anchor, prestressed anchor, hollow anchor and slotted anchor. Torsion test of rod body: clamp the anchor rod body (full length) on the torsion testing machine, and install a supporting device in the middle of the rod body. The rotation speed of the torsion testing machine is 200 r/min ~ 300 r/min, and the anchor rod body is stably loaded to the specified torque within 8 seconds, and it is twisted circularly for 40 seconds, so that abnormal conditions such as fracture and serious deformation should not occur.The test software has powerful data processing function, which can test the corresponding torque under a certain torsion angle, and also test the corresponding torsion angle under a certain torque, and automatically generate test curves such as torque-torsion angle, torque-rotation angle, torque-time, torsion angle-time, etc. The test conditions and test results are automatically saved, and random group test data, test curves and test reports conforming to relevant national standards are displayed and printed.
