JB-300B/500B Semiautomatic Impact Testing Machine


Usage and Characteristics
Pendulum Semiautomatic Impact Testing Machine is used to test anti-impact performance of metal material under dynamic load to judge the quality of material under dynamic load. This machine is semiautomatic control testing machine, easy to operate, high effective. Raising pendulum, impact and pendulum dropping are all controlled by electrical equipment. It can make use of spare energy to raise pendulum automatically and be ready for next impact test. It is developed strictly according to GB/T3808-2002and does impact test with metal material according to GB/T229-2007.It also can satisfy American standards and European standards,like ASTM E23-02a,EN10045,ISO148,ISO83 and other international relative standards.
This impact series of testing machines adopt large torque clutch and high-power motor to make the equipment more stable and no vibration when taking pendulum and releasing pendulum.

Characteristics of JB-300B/500B Series Semiautomatic Impact Testing Machine:
This machine is electric control-box manual control testing machine and makes use of difference between gravitational energy before impacting and spare energy after impacting to display value on dial and get the sample absorbing energy. What the host of this machine adopts casting steel material can make the equipment run steadily at the whole process of test and get more accurate result.
 It is easy to operate and high effective. It can make use of spare energy to raise pendulum automatically and be ready for next impact test. It is applicable for the laboratories, which does continuous impact tests as well as metallurgy, machinery manufacturing industries which do large quantities of impact test.
