Introduction: This machine is equipped with a computer and printer, with dual control dual display. This machine uses plc automatic control and measurement, and according to the rotation of the measured specimen after the hammer anti-yaw angle calculation, the anti-yaw angle β value and the hammer automatically absorbed the work done by the sample, and Impact toughness ak value, and through the computer and special data processing and control software for data editing and generate test reports, test data can also be stored and printed, the average work of three tests, and test time and serial number, etc., but also to achieve data Remote transmission. The machine in accordance with national standards gb / t 3808-202 "pendulum impact testing machine test" development and production, in accordance with GB gb / t 29-207 "metal Charpy pendulum test method" on the impact of metal materials, and Meet jjg 145-207 "pendulum impact testing machine test procedures." If you change the structure and replacement of related parts, at the same time meet the American standard, the European standard astm e23, en 1045, iso 148, iso 83 and other international standards.
