JWJ-10    Series Metal Material Bending Testing Machine

Product model:  JWJ-10，JWJ-15，JWJ-20，JWJ-3B

I. Product overview:

1. The metal wire repeated bending testing machine, also known as the metal wire bending testing machine, is mainly used for the repeated bending test of metal wire, thin plate and thin strip, so as to test the performance and defects of metal materials under plastic deformation in repeated bending.

2. Test principle: clamp the sample of a certain specification through the guide sleeve in the jaws of two specified sizes, press the button, and the sample will bend left and right 90 °. After the sample is broken, it will stop automatically and record the bending times.

3. It is widely used in wire and cable, steel wire factory, prestressed steel wire factory, construction materials, highway transportation, factories and mining enterprises, scientific research institutes, quality inspection units to test the bending performance of metal wires such as steel wire and reinforcement.

4. Applicable standards:

1) GB / T 238-2013 test method for repeated bending of metallic materials and wires

2) GB / t4909.5-2009 test methods for bare wires Part 5: bending test - repeated bending

3) TB / t2809-2005 copper and copper alloy contact wires for Electrified Railways

4) GB / t235-2013 test method for repeated bending of sheet and strip with thickness of metal materials equal to or less than 3mm
