JB-300B semi-automatic impact testing machineDetailed product description：

The JB-300B impact testing machine is used to measure the resistance of metal materials to impact under dynamic loads, in order to determine the quality condition of materials under dynamic loads.
This machine is a semi-automatic control testing machine with simple operation and high work efficiency. It has electrical control for swing, impact, and release, and can automatically swing and prepare for the next test using the remaining energy after punching the sample. It is particularly suitable for laboratories that continuously conduct impact tests and industries such as metallurgy and mechanical manufacturing that conduct a large number of impact tests. The JB-300B impact testing machine complies with the national standard GB/T3808-2002 "Inspection of Pendulum Impact Testing Machines" and conducts impact tests on metal materials according to the national standard GB/T229-2007 "Charpy Pendulum Impact Test Method for Metal Materials".

Technical features of JB-300B semi-automatic impact testing machine:

1. The mainframe of the testing machine is a single supported column structure, with a cantilever hanging pendulum method and a C-type pendulum body;
2. The impact knife is fixed with screws for easy replacement;
3. Sample simply supported beam support;
4. The host is equipped with security protection pins and a safety net;
5. The testing machine is semi-automatic controlled, and the swing, hanging swing, impact, and release swing are all electrically controlled. It can use the remaining energy after punching the sample to automatically swing and prepare for the next test, especially suitable for laboratories that continuously conduct impact tests and metallurgical, mechanical manufacturing and other departments that conduct a large number of impact tests;
6. The testing machine complies with the national standard GB/T3803-2002 "Inspection of Pendulum Impact Testing Machines" and conducts impact tests on metal materials according to the national standard GB/T229-2007 "Charpy Pendulum Impact Test Method for Metal Materials".
