JB-500B is a new generation of pendulum impact testing machine. The impact testing machine is used to determine the resistance of metal materials to impact under dynamic load, so as to judge the quality of the material under dynamic load. This machine is a semi-automatic control testing machine with simple operation and high work efficiency. It is electrically controlled for swing, impact, and placement, and can automatically use the remaining energy after breaking the sample to prepare for the next test. It is especially suitable for continuous testing Impact test laboratories and metallurgy, machinery manufacturing and other industries that do a large number of impact tests.
2. Features
1. The main body of the testing machine is of single support column structure, cantilever type hanging pendulum, and the pendulum hammer body is C type;
2. The impact knife is installed and fixed by screws, which is simple and convenient to replace;
3. Simple beam support of the sample;
4. The host is equipped with safety protection pins and equipped with safety protection nets;
5. The testing machine is semi-automatically controlled. Pendulum raising,hanging pendulum, impact and placement are all electrically controlled, and canuse the remaining energy after breaking the sample to automatically raise the pendulum to prepare for the next test, especially suitable for continuous impact Test laboratories and metallurgical and mechanical manufacturing departments that do a large number of impact tests;
6. The testing machine complies with the national standard GB/T3803-2002 "Inspection of Pendulum Impact Tester", and conducts impact tests on metal materials according to the national standard GB/T229-2007 "Metal Material Charpy Pendulum Impact Test Method".
