The wire repeated bending testing machine is a specialized testing equipment used to determine the plastic deformation ability, toughness, and surface defects of metal wires under repeated bending. During the experiment, clamp one end of the wire sample and pass the other end through the guide groove or lever on the bending arm, causing the sample to bend alternately and repeatedly at a specified angle (usually ± 90 °) around a curved cylinder of a specified radius. Record the number of bends until the sample breaks or reaches the specified number of times, and observe the fracture surface, surface cracks, peeling, folding and other defects.
1、 Basic functional requirements for equipment
1. Adopting a LCD touch screen operating system;
2. The combination of servo motor and worm gear reducer is used to output power, and the test speed can be adjusted arbitrarily, ensuring smooth and noise free operation;
3. A weight hanging plate is required to apply the standard tension force to the sample;
4. By replacing the clamping jaws with different specifications, bending tests can be conducted on materials of various specifications;
5. Number display of bending times.
2、 Main technical parameters:
1. Diameter of wire sample: Φ 1~Φ 10mm;
2. Bending angle: ± 90 °; 3.3 Bending speed:<60 times/minute;
3. Counting range: 0-9999 times.
