Metal Wire Torsion Testing Machine

Application:

The metal wire torsion testing machine is suitable for measuring the ability of metal wire with a diameter (or characteristic size) of 0.1-10.0mm to withstand plastic deformation in one-way or two-way torsion and to display the surface and internal defects of the wire.

This machine is mainly used for the analysis of the mechanical properties of metal wires in the mechanics laboratories of colleges, universities, scientific research departments, and industrial and mining enterprises. It is also widely used for online inspection of production units; the main industries include high-speed steel lines, prestressed steel wire plants, and quality Supervision, scientific research institutes, highway transportation, construction industry, steel wire ropes, wires and cables, copper and copper alloy wires for electrified railways, copper contact wires and other production and use departments.

Principle:

The sample rotates 360 degrees uniformly in one direction around its axis as one twist to the specified number of times or the sample breaks. Two-way torsion: The sample rotates 360 degrees in one direction evenly around its own axis as one twist to the specified number of times, then rotates the same number of times in the opposite direction or the sample breaks.
