This machine uses a high-performance AC motor as the power output, and is equipped with a high-precision reduction motor, so that the power can be output smoothly. The motor is driven by a high-reliability, high-stability inverter to improve the smoothness of the machine operation and reduce power consumption. One side of the chuck is fixed to the motor output shaft, and the other side of the chuck is fixed to the movable bearing seat. The movable seat uses a linear bearing with low friction resistance to ensure the straightness of the axial movement. The axial tension is applied by a weight, and the force is applied to the wire through a 10:1 L-type lever.
Purpose of the equipment:
The metal wire torsion tester is suitable for measuring the ability of metal wires with a diameter (or characteristic size) of 0.1-10.0mm to withstand plastic deformation in unidirectional or bidirectional torsion and displaying surface and internal defects of the wires.
Compliance with standards:
The metal wire torsion tester is applicable to the People's Republic of China standard GB/T 239.1-2012 "Metallic materials Wire Part 1 Unidirectional torsion test method", and also applicable to the international standards ISO 7800:2003 "Metal wire unidirectional torsion test method" and ISO 9649:1990 "Metal wire bidirectional torsion test method"
