Description
Technical Field
The utility model belongs to the technical field of the material performance test, in particular to metal wire material fatigue performance testing arrangement.
Background
Fatigue performance is an important attribute of metallic materials. For example, the shape memory alloy is a special functional material, has excellent superelasticity, memory and damping properties, and also has excellent fatigue, biocompatibility and corrosion resistance, and good comprehensive mechanical properties, so the shape memory alloy is widely used in the industries of aerospace, ships, medical treatment, petrochemical industry and the like. Shape memory alloys are inevitably subjected to periodic irregular stresses or strains in practical applications, and as the number of cycles increases, defects accumulate and cause failure of the alloy. Therefore, the fatigue life test of various metal wire products has important guiding significance on the use of the metal wire products.
The fatigue life of a metal wire is generally tested by testing the fatigue life of the wire in axial reciprocating stretching on a stretching machine. Taking a Qinzhii shape memory alloy wire as an example, the axial reciprocating tensile fatigue life of the wire is tested under the action of electric heating and load. Generally, the superelasticity or memory performance of the memory alloy wire is tested by a repeated bending method, and the memory alloy wire is rarely used for testing the fatigue life. Moreover, the number of repeated bending is small, and the bending is often done manually. Generally, the number of times of repetition is less than one hundred at most, and the memory alloy wire is not required to be broken. Tobushi et al proposed a rotating Bending fatigue method (Bending rotation fatigue) to test the fatigue properties of shape memory alloys. The method is effective and practical for testing the shape memory alloy wire, and more people adopt the method to research the fatigue performance of the shape memory alloy. The fatigue performance of the wire is tested by using a rotary bending fatigue method for reference.
The metal wire fatigue performance testing device provided by the invention has the advantages that the two clamping shafts are controlled to rotate by one motor, so that the purpose of synchronous rotation of the two ends of a sample is realized. Two silk material sample centre gripping axles are respectively on a slidable guide rail, adjust centre gripping axle distance according to test silk material diameter and demand test stress condition, drive silk material both ends through the motor and rotate in opposite directions in the test, can carry out the rotatory bending process of last ten thousand times, until the metal silk material fracture. When the metal wire is broken in the fatigue test, one end of the wire touches the broken wire sensing shaft, the sensing shaft sends out a test stop instruction, and the display shaft records the time of repeated rotary bending. When the bending fatigue fracture life is tested, the metal wire can be loaded with load according to actual use conditions, and the bending fatigue life under certain stress conditions is tested.
