How to use the impact test machine and precautions

The impact tester is used to test the impact resistance of metal materials under dynamic loads. It is not only a necessary testing instrument for metallurgy, mechanical manufacturing and other units, but also an indispensable testing instrument for scientific research institutions to conduct new materials research. Below is mainly to introduce the use of impact testing machines and precautions for use. Let’s learn about it together.

1. Method of using impact test machine

1. Turn on the power supply of the impact tester and start the swing to ensure that the pendulum has been placed in the pre-lift hook position, pointing to the right 150°,

2. Place the sample and place the sample horizontally on the bracket to cause impact load on the back of the sample notch.

3. Select the range according to the hammer head and turn the knob to the corresponding range position.

4. Pull the cancel and impact buttons to allow the pendulum to fall freely, causing the sample to be subjected to impact load.

5. Read the numerical values ​​and record the test data to prepare for the next impact.

2. Precautions for using impact testing machine

1. Turn the pointer to the maximum position of the dial and check the zero position.

2. Connect the power supply and turn on the switch on the side of the host. At this time, the power indicator light is on. Hold the handle box and pull the button switch to the "On" position. Press the "Swing" button to check whether the pendulum rotates in a counterclockwise direction. If the direction is incorrect, the power supply should be cut off and the power supply should be changed immediately and the power phase should be changed.

3. Place the sample, and the gap faces the side that hits the blade, and use the sample to align the plate.

4. Press the "Reject" button, the insurance pin exits, and then press the "Impact" button to push the hanging mechanism to remove the sliding mechanism. The pendulum will fall and impact→automatic swing→hung swing, and the insurance pin extends out. At this time, an impact test is completed and the number pointed by the pointer is recorded, that is, the absorption work of the sample.

5. When you want to put the sway, press and hold the "put the sway" button, the safety pin returns, the valve is energized with an electromagnetic magnet, the push-off hanging mechanism rotates downward, the electromagnetic clutch is attracted, the main motor rotates, and the pendulum rotates clockwise. When it turns to the plumb position, release the button and stop.

6. Turn off the twist switch on the button box, the side switch on the main unit and the main power supply in turn.

7. Choose a pendulum according to energy requirements. When changing the swing, first screw out the compression nut, insert it into the grooves on both sides of the swing rod joint with a disassembler, twist the screw, press against the end surface of the swing shaft to exit, and replace the required pendulum hammer.

8. When using, pay attention to whether the jaw support, pendulum, etc. are reliably fastened to prevent the test results from being inaccurate and accidents.

9. When the hanging mechanism has not been hung on the hanging mechanism during the swaying process, the staff shall not move or work within the swing range of the pendulum to avoid accidental power outage and danger.

To sum up, this is a detailed introduction to the usage methods and precautions of impact testing machines. I believe everyone has a certain understanding of this after reading them.
