Microcomputer-controlled ultra-low temperature fully automatic impact tester JBDW-300C

1. Performance description

JBDW-300C low-temperature impact testing machine is used to test the performance of metal materials to resist impact under dynamic loads. It is an essential testing instrument for metallurgical machinery manufacturing and other units, and is also an indispensable testing instrument for scientific research institutions to conduct new materials research.

1. This machine adopts fully automatic control, and the swing, hanging, feeding, positioning, impact and temperature adjustment equipment are all electrical and mechanically controlled. It is equipped with a special feeding device to automatically feed the material and automatically position the sample cross-section. The impact time until the sample is released from the oven is no more than 2 seconds, which meets the requirements of the metal low temperature chamonix impact test method. After impacting the sample, the remaining energy can be used to automatically swing, and prepare for the next test, which has high working efficiency;

2. The main body of the test machine is a split structure, cantilever hanging pendulum method, and the pendulum hammer body U-shaped;

3. The impact knife is installed and fixed with screws, making it easy to replace;

4. Sample simple-supported beam type support;

5. The host is equipped with a security protection pin and is equipped with a security protection net;

6. The test machine complies with the national standard GB/T3803-2002 "Inspection of Pendulum Impact Test Machine", and conducts impact tests on metal materials according to the national standard GB/T229-2007 "Metal Shabby Notch Impact Test Method".
