JB-150B-type impact testing machine is used for the measuring the performance of metal materials’ resistance in the process of dynamic loading impact, in order to judge the character of the material under dynamic load. In accordance with the national standard GB/T3808-2002 "pendulum-type impact test machine”, this testing machine has been developed and produced; then according toGB/T229-2007"metal Charpy notched impact test method" ,the metal material has been impact tested, the maximum impact energy is 150J and with one 75J Swinging hammer ,the specimen cross-section used for the 10 × 10mm; testing machine has a larger impact energy, so mainly for the ferrous metals of larger impact toughness testing , such as iron and steel and their alloys.
The use of the difference of potential energy between prior impact and the remaining potential energy ,showing the degree on the scale, getting the sample to absorb reactive power; It is semi-automatic testing machine on the operation, easy to operate, efficient for working, after cutting off the specimen, the remaining energy of the automatic swinging will be ready to do the next impact testing, so in laboratory of doing cantonal testing and other metallurgy, machinery manufacturing departments of doing substantial impact test ,this machine can manifest better advantages.
If users want to expand its function, according to ASTM E23-81 "metal material notch impact test pilot" for the impact test, they can also contact us for special set of custom-made to meet this standard bob (150J, 75J, and a pair of abutment).
