What is a wire bending testing machine?
In the field of industrial production and material testing, the wire bending testing machine is an important testing equipment used to evaluate the bending resistance and fatigue life of wires, cables, metal wires and other materials. With the recent rapid development of manufacturing and materials science, the application and discussion of wire bending testing machines has increased significantly. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce in detail the definition, use, working principle and market data of the wire bending testing machine.
1. Definition of wire bending testing machine
The wire bending testing machine is a testing equipment specially used to simulate the repeated bending of wires in actual use. By setting the bending angle, frequency and number of times, the wire is detected for breaks, cracks or other performance degradation to evaluate its durability and reliability.
2. Main uses of wire bending testing machine
1.Electronics industry: Test the bending life of electronic cables such as headphone cables and data cables.
2.Automobile industry: Evaluate the durability of automotive wiring harnesses.
3.Aerospace: Test the fatigue performance of high-strength steel wires and cables.
4.Scientific research institutions: Study the behavior of new materials under dynamic loads.
3. Working principle of wire bending testing machine
The wire bending testing machine drives the fixture through a motor to repeatedly bend the wire within a set angle. The number of bends is recorded during the test until the wire breaks or reaches the preset number of times. Some high-end equipment can also monitor resistance changes, temperature and other parameters in real time.
