JBDS-300Y digital automatic temperature impact testing machine

I. Introduction:

JBDS-300Y digital automatic temperature impact testing machine for the performance of impact resistance of metal materials under dynamic load tested, metallurgy, machinery manufacturing, and other units of the necessary testing equipment, also new materials research unit indispensable test instrument.
Technical Features:
1, The machine adopts MCU control, Yang pendulum, hanging swing, feeding, positioning, shock and temperature adjustment devices are electrical, mechanical control, with special feeding device automatic feeding, automatic sample positioning section. Sample time is not released to impact more than two seconds, meet the requirements of low-temperature metal Charpy impact test method can be used after the impact of the sample remaining energy automatic Yang pendulum, do the next test preparation, high efficiency.;
2 tester body is split structure, cantilevered hanging pendulum fashion, the pendulum hammer U-shaped;
3, the impact of knife with screw mounting, easy replacement;
4, the specimen simply supported beam-like support;
5, the host is equipped with safety pin, and is equipped with a safety net;
6, the test machine in line with the national standard GB / T3803-2002 (test Charpy impact test machine), according to national standard GB / T229-2007 (Charpy impact test) of metal material impact test.
