Computer control 300j pendulum charpy impact testing machine

The impact testing machine is mainly used for measuring the metal material resistance performance under dynamic load, in order to determine the material properties under dynamic load.

It’s a necessary testing machine,not only used in the metallurgy,machine manufacture etc areas, but also used for the science research.

Product features:

1 One-body cast frame design of seat and column provide high stability.

2 Front and rear columns are symmetrical. Pendulum arm is designed of cantilever beam support, with simple structure and high machined precision.

3 Apply high precision bearing with small friction. Absorbing energy without loading is less than 0.3%.

4 Double reduction gear system replaces old style drive system with high efficiency and avoiding transmission failure.

5 High rigid pendulum arm prevents axial and transverse vibrations.

6 Exchangeable pendulum is simple to change to satisfy impact energy of 150J, 300J, 450J, 600J, 750J.

7 Electromagnetic release of pendulum hammer and electromagnetic clutch for locking the pendulum and raising it to its initial position. A damper is equipped to prevent strong bump when clutching.

8 Full-closed enclosure with high safety to prevent broken sample from splitting. Protective screening has interlock door. When the door opens, most operations can’t work to avoid any wrong operation.
