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.
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.
Performance Characteristics
1. Test speed: stepless speed regulation, which can meet the requirements of scientific research level tests;
2. Rotating chuck: The twisting chuck should be able to rotate in both directions around the axis of the specimen, and the speed of the rotating chuck should be adjustable, with uniform and stable speed;
3. Chuck: The positioning chuck can move axially, and the clamp type fixture can ensure that the sample does not slip;
4. Ruler display: The length of the wire test is indicated by the ruler on the table;
5. Locking mechanism: Adjust the length of the wire and lock it at any position;
6. LCD display: large LCD screen, maximum display turns 999999;
7. Force application mechanism: It can generate a tensile force of no more than 2% on the wire, ensuring that the wire is straight during the test, or disconnecting and stopping the machine after the wire breaks, ensuring accurate data;
8. Unique spring buffering mechanism: ensuring the buffering of the clamp seat on the support after the wire is broken, extending the service life;
9. Cam mechanism: a bright chrome plated handle that drives the cam, making wire clamping and straightening more convenient;
10. Automatic sealing of test circle values after specimen fracture
