1、 Main purpose
The metal wire torsion testing machine is mainly used to determine the ability of metal wires with diameters ranging from 1 to 10mm to withstand plastic deformation in unidirectional or bidirectional torsion. During the testing process, surface defects of the wire can be displayed. The testing machine is loaded by a motor, the rotation sensor detects the number of twists, and the LCD displays the detection results.
2、 Scope of application
For fine wires such as steel wire, copper wire, aluminum wire, etc., the commonly used ones are stainless steel wire, copper plated steel wire, galvanized steel wire, silver plated steel wire, etc., which are suitable for testing the torsional performance of materials in mechanical laboratories of relevant scientific research departments, various colleges and universities, and industrial and mining enterprises; Very suitable for online testing of wire production units and incoming inspection of wire units; Widely used in steel mills' high-speed lines, prestressed steel wire factories, quality supervision, research institutes, highway transportation, construction industry, steel wire ropes, wires and cables, copper and copper alloy wires for electrified railways, aluminum wires and other production and usage departments.
