Semi automatic pendulum impact testing machine

Testing machine type: semi-automatic pendulum impact testing machine
Specification and model: JB-B series
Impact energy: 300J/500J
1、 Product Introduction:
This series of semi-automatic pendulum impact testing machines 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. It is an essential testing instrument for metallurgical, mechanical manufacturing and other units, as well as an indispensable testing instrument for scientific research units to conduct new material research. This series of models is currently the most commonly used impact testing machine on the market.
2、 Performance characteristics:
The mainframe of the testing machine is a double supported column structure, with a cantilever hanging pendulum method and a U-shaped pendulum body; The impact knife is fixed with screws for easy replacement; Sample simply supported beam support; The host is equipped with security protection pins and a safety net; The testing machine is equipped with semi-automatic control, swing, hanging swing, impact, and release swing, all of which are electrically controlled. It can automatically swing and prepare for the next test using the remaining energy after breaking the sample. It is particularly suitable for laboratories that conduct continuous impact tests and metallurgical and mechanical manufacturing departments that conduct a large number of impact tests;
The 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".
