What is a wire repeated bending testing machine?
In industrial production and materials research, wire quality and durability are crucial evaluation indicators. As a professional testing equipment, the wire repetitive bending testing machine is widely used to test the bending properties of metal wires, cables, steel wire ropes and other materials. This article will introduce in detail the definition, working principle, application fields and related technical parameters of the wire repeated bending testing machine.
1. Definition of wire repetitive bending testing machine

The wire repeated bending testing machine is a device used to test the durability and fatigue resistance of wires under repeated bending conditions. By simulating the bending of wires in actual use, the device can evaluate key indicators such as the wire's bending life, breaking strength, and material toughness.
2. Working principle
The working principle of the wire repeated bending testing machine is to fix both ends of the wire through clamps, and then drive the motor to bend the wire repeatedly at a set angle and frequency. During the test, the device records the number of times the wire is bent until it breaks, thereby assessing its durability.
3. Application fields
Wire repeated bending testing machines are widely used in the following fields:
| field | Application Notes |
