screw spikes are instruments used to measure the torsional properties of steel wires. Torsional performance is an important performance index of wire rod. Wire torsion testing machine is mainly used in universities, scientific research departments, mechanical laboratories of industrial and mining enterprises to analyze the mechanical properties of metal wires, and is also widely used in online testing of production units. The industry mainly includes steel high-speed wire, prestressed steel wire factory, quality supervision, scientific research institutes, road traffic, construction industry, steel wire rope, wire and cable, electrified railway copper and copper alloy wire, copper contact wire and other production and use departments.

The principle of one-way torsion of the wire torsion tester: the sample rotates 360 degrees at a uniform speed around its own axis in one direction for a torsion to the specified number of times or the sample fracture. Bidirectional torsion: The specimen is evenly rotated 360 degrees in one direction around its own axis as a single twist to the specified number of times, and then rotated the same number of times in the opposite direction or the specimen breaks.

screw spikes host introduction:

1. Mechanical structure: The torsion testing machine uses high-performance AC motor as power output, and is equipped with high-precision deceleration motor, so that the power output is smooth. The motor is driven by high reliability and high stability frequency converter, which improves the smooth running of the machine and reduces the power consumption. One side of the chuck is fixed on the output shaft of the motor, and the other side is fixed on the movable bearing seat. The moving seat adopts linear bearing with small friction resistance to ensure the straightness of axial movement. The axial tension is applied by weight, and the force is applied to the wire by a 10:1 L-shaped lever.

2. Control unit: The control system adopts imported microprocessor, and the mature control mode ensures the control accuracy and operation stability of the control unit. The torsion testing machine uses an industrial LCD screen, which has the characteristics of long life, stable performance and wide viewing Angle. The counter is a kind of Hall sensor with strong anti-interference ability, high sensitivity and good dynamic performance. The torsion testing machine has the function of automatically judging the broken line.
