Test process of steel strand tensile testing machine

Test process of steel strand tensile testing machine

Tension testerIt is often used for tensile tests of steel strand materials. Our company's technicians have given a detailed introduction to the tensile tests of steel strands:

1. Open the oil supply valve to lift the piston up by 5 to 10mm

2. Enter the software and click on the new test strand tensile test window, enter the corresponding parameters, and clear the test force, displacement, and deformation. Do not click Run.

3. Clam the steel stranded wire (Note: the clamping part of the steel stranded wire is wrapped with a sand cloth, the height dimension is about 180mm).

4. Open the oil supply valve to pre-pull the test force of about 20KN, and then set the load (Note: Do not click to run the software part of this step)

5. Clamping the extensometer (Note: the extensometer must be clamped)

6. Deformation clears (Note: Force value and displacement do not need to be cleared)

7. Unplug the positioning pin on the extensometer and click the software to run the constant loading speed.

8. After the software prompts to remove the extensometer, quickly remove the extensometer (Note: Do not close the oil supply valve during this process)

9. Continue to test the sample to be opened. After the test is completed, close the oil supply valve, remove the sample, and open the oil return valve to return oil;

10. View, organize and print the test data! (See the software manual for details)
