JB-300B semi-automatic impact testing machine
First, the product introduction
JB-300B impact testing machine is used to determine the resistance of metal materials to impact under dynamic load, so as to judge the quality of materials under dynamic load.
This machine is a semi-automatic control testing machine, simple operation and high efficiency, pendulum, impact, pendulum electrical control, and can use the remaining energy after breaking the specimen to automatically swing ready for the next test, especially suitable for the continuous impact test of the laboratory and a large number of impact tests of metallurgy, machinery manufacturing and other industries. JB-300B impact testing machine conforms to the national standard GB/T3808-2002 "Pendulum Impact Testing Machine Inspection", according to the national standard GB/T229-2007 "Metal Material Charpy Pendulum Impact Test Method" for impact test on metal materials.
Second, technical characteristics
1. The main engine of the testing machine is a single-support column structure, a cantilever-type pendulum type, and a pendulum hammer body U-shaped;
2. The impact knife is screw-mounted and fixed, and the replacement is simple and convenient;
3. Specimen simple support beam support;
4. The host is equipped with a security protection pin and equipped with a safety protection net;
5. The testing machine is semi-automatic control, pendulum, pendulum, impact, pendulum are all electrical control, and can use the remaining energy after punching off the specimen to automatically swing to prepare for the next test, especially suitable for the continuous impact test of the laboratory and a large number of metallurgy, machinery manufacturing and other departments that do impact test;
6. The testing machine conforms to the national standard GB/T3803-2002 "Inspection of Pendulum Impact Testing Machine", and the impact test of metal materials is carried out according to the national standard GB/T229-2007 "Metal Charpy Gap Impact Test Method".
