Five Advantages Of Products The wire torsion tester is suitable for measuring the ability of steel wires Unidirectional torsion Torsion speed: 30; 60; 90; 120 revolutions per minute Testing machine size: 1360*430* 600mm easy to operate Conform to the standard In accordance with GB/T 239-1999, test methods for torsion of metallic wires, ISO 7800:1984. The product description The wire torsion tester is suitable for measuring the ability of steel wires with diameters (or characteristic dimensions) of 0.5-10.0mm to withstand plastic deformation in unidirectional or bidirectional torsion and for displaying defects on the surface and inside of wires. The main function Unidirectional torsion: the sample rotates 360 ° uniformly in one direction around its axis as a single torsion to a specified number of times or the sample breaks bidirectional torsion: the sample rotates 360 ° uniformly in one direction around its axis as a single torsion to a specified number of times, then rotates the same number in the opposite direction or the sample breaks. The sample standard The specimen should be as flat as possible, straightened if necessary, but the surface should not be damaged or the specimen distorted. In order to make the specimen straight during the test, some form of tension force should be applied, which should not be greater than 2% of the corresponding force value of the nominal tensile strength of the test wire. Technical parameters 1. Can clamp metal wire diameter: 1mm ~ 10mm 2. Distance between the two plus heads: 0mm ~ 500mm 3. Specific outside diameter of clamp: 65mm 4. Torsion speed: 30; 60; 90; 120 revolutions per minute
