What is a metal wire repeated bending testing machine?
The metal wire repeated bending testing machine is a special equipment used to test the durability and performance of metal wires under repeated bending conditions. It is widely used in metal products, wires and cables, building materials and other industries to evaluate the flexibility, fatigue resistance and service life of materials. This article will introduce in detail the principle, application scenarios, technical parameters of the device, as well as hot topics and hot content in the past 10 days.
1. Working principle of metal wire repeated bending testing machine
The metal wire repeated bending testing machine tests the fatigue resistance and durability of metal wires by simulating the repeated bending stress they experience in actual use. Equipment usually consists of drive systems, fixtures, counters and control systems. During the test, the metal wire is fixed on the fixture and bent repeatedly through the drive system until it breaks or reaches a preset number of times. The number of bends and the location of the break are recorded.
