The computer-controlled impact testing machine 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 and prepare for the next impact test. Therefore, it can better reflect its advantages in the laboratory that continuously conducts impact tests and the metallurgical and machinery factories that do a large number of impact tests.
This machine is equipped with a computer and a printer, with dual control and dual display functions. The machine adopts PLC automatic control and measurement, and calculates according to the reverse lift angle of the pendulum after breaking the sample measured by rotary weaving, and automatically displays the reverse lift angle β value and the absorption work done by the pendulum to the sample, and Impact toughness ak value, can edit data and generate test report through computer and special data processing and control software, can also store and print test data, average work of three tests, test time and serial number, etc. remote transmission.
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.
This machine complies with JJG 145-2007 "Verification Regulations of Pendulum Impact Testing Machine". It can meet the requirements of international standards such as American Standard, European Standard ASTM E23, EN 10045, ISO 148, ISO 83 and so on.
