5 steps for operation of semi-automatic impact tester

Testing machineWith the rapid development of the industry, more and more industries use impact testing machines as the qualified regulations for testing products. Some customers will purchase second-hand impact testing machines for certain reasons, and their operation is unclear. Today, our company's technology introduces the following procedures of the impact testing machines produced by Hengsi Shanda.

First of all, before performing the impact test, we need to replace the appropriate pendulum according to the material's impact energy requirements (the impact energy of the large pendulum is 300J and the small pendulum is 150J).

Then, openImpact testing machineThe body power switch, the hand-held operator makes the pendulum empty (no sample placement), check whether the passive needle of the dial points to zero. If it does not point to zero, the pointer position should be adjusted so that the pointer is zero when the empty point is played.

Third, use wooden blocks to place the pendulum on the edge of the support, use the notch to center the sample to make the impact sample notch at the center of the span of the support, and the notch surface is on the impact tension side.

Fourth, press the "Start" button to lift the pendulum, and after it reaches the set height on the spot and stabilize, clear all obstacles in the blow ring of the pendulum shelves, and turn the dial pointer to the strike energy scale.

Fifth, press the "Impact" button and knock the sample off by dropping the hammer. When the pendulum swings back, press the "Brake" button. When the pendulum stops swinging, record the impact energy. After the test is over, turn off the operator power supply and the impactor power supply, and hang the operator back to its original position.
