Matters and maintenance that need to be inspected before use of metal tensile testing machine

The metal tensile testing machine can conduct tensile, compression, bending, tearing, 90° peeling, 180° peeling, shearing, adhesive force, pulling, pulling, pulling, 180° peeling, shearing, adhesion, pulling, pulling, elongation, etc., castings, steel plates, steel strips, non-ferrous metals, automotive parts, alloy materials and other non-metallic materials and metal materials.

The metal tensile testing machine is a material testing machine. It can conduct tensile, compress, bending, tearing and other tests on metal and non-metal materials. Before using the metal tensile testing machine for testing, you need to check the equipment to avoid problems during the test. How to comprehensively observe, detect and debug the metal tensile testing machine? Below, our technicians will share with you the matters and maintenance of the metal tensile testing machine before use.

1. Things to check before use of metal tensile testing machine:

1. Is the load sensor verification standard?

The general measurement and verification equipment has 10% or 20% of the maximum load load of the equipment as the initial value of the calibration, while many load sensors with poor quality happen to have a greater error than ≤10%. If there is indeed a problem with the accuracy of the load sensor, we should replace it in time.

2. Is the crossbeam movement speed of the metal tensile tester normal?

The results obtained by different tensile test speeds are different, so the test speed needs to be checked and confirmed.

3. The range of the tensile tester is not enough

Estimate whether the maximum force value of the material in the tensile test exceeds the maximum range of the test machine. If it exceeds, please replace the test material.

4. Is the installation position of the displacement sensor of the metal tensile test machine correct?

Due to different designs, the installation locations are also different: but the ones installed on the screw will be more accurate than those installed on the motor.

5. Is the synchronous belt or speed reduction device damaged due to the increase in use time?

As the use time of the synchronization belt or speed reduction device increases, the aging life of these two parts will be accelerated, and not replacing it in time will affect the test results.

6. Whether the safety protection device of the metal tensile tester has failed.

2. The maintenance methods of metal tensile testing machines are as follows:

1. Before the test, the system must be preheated for more than 20 minutes to minimize the temperature impact;

2. The oil used for the buffer should be kept clean. If the oil level is less than two-thirds of the depth of the cylinder, it should be replaced immediately;

3. Before starting the machine, check whether lubricating oil should be added to the frictional moving parts;

4. Before adding the test piece, the metal tensile tester must jam the brake handle, and release it after adding the test piece;

5. Refueling is not allowed on the main bearing of the dynamometer. The surface of the friction wheel in the gearbox must not be refueled or oil stains splashed. The friction surface should be absolutely clean and the inclined block on the swing arm must not be violently impacted;

6. After the test is completed, after the power is cut off, the test machine will be cleaned and protected in a timely manner;

7. The tensioner is maintained twice a month on average.

The above are the matters and maintenance that need to be checked before use of the metal tensile tester. I hope the above brief introduction can help you.
