Metal Wire Torsion Testing Machine EZ-5

Main Purpose: The metal wire torsion testing machine is suitable for determining the ability of metal wires with a diameter (or characteristic dimension) of 3-5.0mm to withstand plastic deformation during unidirectional or bidirectional torsion, as well as revealing surface and internal defects of the wire.

Principle: Unidirectional Torsion: The specimen rotates uniformly 360 degrees around its own axis in one direction as one torsion cycle, continuing until the specified number of cycles is reached or the specimen fractures. Bidirectional Torsion: The specimen rotates uniformly 360 degrees around its own axis in one direction as one torsion cycle until the specified number of cycles is reached, then rotates the same number of cycles in the opposite direction or until the specimen fractures.

Applicable Standards: The metal wire torsion testing machine complies with the standards GB/T239.1-2012 "Metallic Materials—Wire—Part 1: Method of Unidirectional Torsion Test" and GB/T239.2-2012 "Metallic Materials—Wire—Part 2: Method of Bidirectional Torsion Test." It also meets the international standards ISO7800:2003 "Metallic Materials—Wire—Unidirectional Torsion Test" and ISO9649:1990 "Metallic Materials—Wire—Bidirectional Torsion Test."

Application Fields: This machine is primarily used for mechanical property analysis of metal wires in力學(xué) laboratories of universities, research institutions, and industrial and mining enterprises. It is also widely used for online inspection in production units. Key industries include high-speed wire rod mills, prestressed steel wire plants, quality supervision, research institutes, highway transportation, construction industry, wire rope, electric wire and cable, copper and copper alloy conductors for electrified railways, copper contact wires, and other production and usage departments.

Host Introduction: 1. Mechanical Structure: This model uses a high-performance AC motor as the power output, paired with a high-precision reduction motor to ensure smooth power delivery. The motor is driven by a highly reliable and stable frequency converter, improving machine operation smoothness and reducing power consumption. One chuck is fixed to the motor output shaft, while the other is fixed to a movable bearing seat. The movable seat employs linear bearings with low frictional resistance, ensuring straightness in axial movement. Axial tension is applied using weights, transmitted through a 10:1 L-type lever to exert force on the wire. 2. Control Unit: The control system utilizes imported Atmel microprocessors combined with mature control methods, ensuring control accuracy and operational stability. The display screen uses an industrial-grade LCD with features such as long lifespan, stable performance, and wide viewing angles. The counter employs a Hall sensor with strong anti-interference capability, high sensitivity, and good dynamic performance. The machine automatically detects wire fracture.
