When the electronic tensile tester is doing the tensile test, sometimes the product has not been broken, but the test has already indicated the end, what is the reason for the continuous pulling of the electronic tensile tester? Today, the national instrument Xiaobian to analyze with you the reasons!
Analysis of the causes of the pulling of the electronic tensile testing machine
1. Test product material reasons
As we all know, the tensile testing machine can test a variety of materials, such as metal, rubber, yarn, fiber and so on. Some materials are more difficult to break, or they can be said to not need to be broken, such as fibers or yarns. Products like this will have some adhesion after breaking, and the electronic tensile testing machine has already It is judged that it is “pushed off”. In this case, it is necessary to adjust the tension machine sensor and replace it with a higher precision sensor.
2.Electronic tensile testing machine fixture selection reasons
There are many kinds of electronic tensile testing machine clamps, and the corresponding materials have corresponding fixtures for testing. If they do not match, sometimes the pulling situation will be caused. For example, when testing the tension of the fabric, if the fixture is narrower, and the fabric is not completely clamped, the middle part will be broken, but the part that is not clamped is not broken, so when testing The corresponding fixture should be used for testing.
3.Electronic tensile testing machine fixture is not clamped
According to the second reason, when the clamp is clamped, the equivalent is that some of it is clamped, and some of it is not clamped, the clamped part can be pulled off, and the whole part is not pulled.
4. Electronic tensile tester range reason
If the electronic tensile testing machine has no way to meet the maximum pulling force of the tested product, it will cause the tensile testing machine to be fully loaded when it is halfway pulled, which will cause the continuous pulling situation. The tensile testing machine was used for testing.
5.Electronic tensile testing machine stroke reason
Some test products have a large deformation, so they have to be pulled very long, and the longer the pull, the greater the effective stroke requirement for the electronic tensile testing machine. When the tensile testing machine has been running full, the product has not been broken. It will cause continuous tension. In this case, it is necessary to replace the tensile tester with a larger effective stroke.
