Precautions for operating impact testing equipment during testing

The impact testing machine equipment refers to the device that applies impact testing force to the specimen and is mainly used to determine the impact resistance performance and quality of metal materials. Attention should be paid to some matters during the impact testing machine to avoid any deviation in the test results.

Let's take a detailed look below!

1. During the experiment, operators and observers must be outside the safety warning line to avoid being affected by the experiment and ensure their personal safety.

2. When disassembling the impact testing machine equipment, there are strict rules. First, remove the protective net below, then loosen the nut, and then use the swing extractor to push the swing out. It is important to use your right hand to lift the joint of the swing rod and slowly move the swing to the left. At the same time, gently place it on the base of the testing machine and remove the pendulum.

3. When installing the pendulum, gently place it on the base and hold the joint of the pendulum rod with your right hand. Slowly move the pendulum to the sample support, adjust the dial with your left hand, align the pendulum head with the hole slot, push the pendulum in, tighten the nut, and install the protective net. In fact, the steps of installing and disassembling the pendulum are opposite. As long as you learn how to install, you will know how to disassemble.

4. Before using the equipment for testing, it is necessary to adjust the focal length to ensure that all basic work is completed, so as to ensure the accuracy of the test results.

5. When heating up the experiment, the temperature should be controlled at around 30 ℃ to prevent alcohol from self igniting and causing safety accidents.

6. The requirements for the samples in the sample box are very strict, they must meet the requirements of no iron filings, no dust, and no burrs, so as to ensure the accurate tensile strength of the material testing.

7. When testing, click the swing button. If the pendulum does not rotate clockwise, cut off the power in a timely manner, recalibrate it, and make it rotate clockwise.

8. During the experiment, in order to ensure the accuracy of the data, one sample is not subjected to impact, while two samples are subjected to impact, in order to ensure the accuracy of the data.

The above are the precautions that the impact testing machine needs to pay attention to during the test to avoid deviations in the results that may affect the accuracy of the test.
