ASTM E23 Lab Testing Machine Digital impact testing machine

Use and Characteristics of Digital Impact Testing Machine:

The digital display impact tester is used to measure the impact resistance of metal materials under dynamic load, so as to judge the properties of materials under dynamic load. The absorbed energy of the sample is obtained by the way the difference between the potential energy before the pendulum impact and the residual potential energy after the impact is displayed on the dial. The maximum impact energy is 300J, and a 150J pendulum is attached, and the section of the sample used is (10×10) mm. This machine has large impact energy and is suitable for ferrous metals with high impact toughness, such as steel and its alloys.

This machine is a semi-automatic control testing machine. The electrical appliances control automatic swing, impact and swing. It is easy to operate and has high work efficiency. After the sample is broken, the remaining energy is used to automatically lift the pendulum to prepare for the next impact test. Therefore, it can better reflect its advantages in the laboratory that continuously performs impact tests and the metallurgical and machinery factories that perform a large number of impact tests.

This machine is equipped with a liquid crystal digital display controller, with dual control and dual display function. The liquid crystal digital display controller adopts PLC control and measurement, and calculates according to the reversal angle of the pendulum after the sample is punched by the rotary editor, and automatically displays the reversal angle β value and the absorption work done by the pendulum to the sample, and the AK value of impact toughness, the test data, the average work of three tests, and the test time and serial number can also be printed with the addition of micro-beating.

The main body of the machine is made of cast steel, which makes it rigid and stable during the whole test process, with strong impact resistance, not easy to deform, accurate test results and long service life. The use of high torque clutch and high power motor makes it more stable and vibration-free when taking and placing the pendulum.
