Structure and functional characteristics of pendulum impact testing machine

The function of the pendulum impact tester is to measure the impact resistance of metal or non-metallic materials under dynamic load, so as to judge the properties of the material under dynamic load. According to the different experimental materials and standards, the pendulum impact testing machine is divided into Charpy impact testing machine, Izod impact testing machine, Charpy and Izod combined impact testing machine and other specifications.


Different specifications, different impact energy, different control methods, and different structures. But generally it is composed of: host body, transmission mechanism, hanging and detaching mechanism, automatic lift pendulum device, dial, pendulum, protective device, electrical part and so on.

Precautions for pendulum impact testing machine
1. It is strictly forbidden to put the sample before the pendulum is hung up. Before placing the sample, make sure that the pendulum has been hung stably and the safety pin has been ejected;

2. The testing machine adopts three-phase four-wire system 380V, 50Hz power supply, please be sure to connect it correctly and connect the ground wire to ensure the normal operation of the testing machine and the personal safety of the operator;

3. When you debug the testing machine and press the "Pull" button first, the pendulum should turn clockwise when you face the front of the testing machine. If the direction is wrong, cut off the power immediately (or turn off the toggle switch on the hand control box) to change the power phase sequence, so that the testing machine can work normally.
