Ⅰ.Name:Microcomputer controlled metal impact testing machine

Ⅱ.Performance description:

This machine is mainly used to measure the resistance of metal materials under impact under dynamic load. It is an indispensable testing instrument for metallurgical and mechanical manufacturing units. It is also an indispensable test instrument for scientific research units to carry out new material research. This series of models is also The impact testing machine is currently on the market.

• This machine is a microcomputer-displayed semi-automatic impact testing machine. It adopts PC microcomputer control, which can realize computerized operation such as tilting, impact→measurement→calculation→screen digital display→printing, high work efficiency and high test precision. After impacting the sample, the remaining energy is automatically swayed, ready for the next test, easy to operate, and high in work efficiency. Especially in the laboratory that continuously performs the impact test and the metallurgical and mechanical manufacturing industries that do a lot of impact tests, it can better demonstrate its superiority. The computer can calculate and absorb the shock absorption work of the material, the pendulum angle and the test average. Remote data transmission is also possible according to user needs.
• The pendulum is designed as a U-shaped pendulum, which ensures the accuracy of the strike center and the pendulum torque is accurate;
• The impact knife is fixed by screws, which is easy and convenient to replace;
• It is equipped with safety protection pins and is equipped with a fully enclosed protective cover;
• Microcomputer control, complete the whole process of pendulum, impact, automatic lifting and re-impact multiple tests according to the instructions.
• The test machine is equipped with a load cell and an angular displacement sensor with high-speed sampling, storage and calculation functions;
• The test machine conforms to the national standard GB/T3803-2002 "Inspection of pendulum impact tester", and the impact test of metal materials according to GB/T229-2007 "Metal Charpy Notched Impact Test Method"
