Name：Digital charpy pendulum impact testing machine for metal
Model：
Description：Digital charpy pendulum impact testing machine for metal is used to measure the impact resistance of metal materials under dynamic load so as to judge the properties of the material under dynamic load. The absorbed energy of the sample is obtained by the way that the difference between the pre-position energy of the pendulum impact and the remaining position energy after the impact is displayed on the LCD.

Digital charpy pendulum impact testing machine for metal
Digital type impact tester is used to measure the impact resistance of metal materials under dynamic load so as to judge the properties of the material under dynamic load. The absorbed energy of the sample is obtained by the way that the difference between the pre-position energy of the pendulum impact and the remaining position energy after the impact is displayed on the LCD. The maximum impact energy is 500J, and a 300J pendulum is attached. The section of the sample used is (10×10)mm. Digital pendulum impact testing machine for metal has a large impact energy and is suitable for ferrous metals with high impact toughness, such as steel and its alloys.
Digital charpy pendulum impact testing machine for metal is a semi-automatic control testing machine, electrical control automatic swing, impact and put pendulum, easy operation, high work efficiency. After throwing off the sample, the remaining energy is automatically thrown to prepare for the next impact test. Therefore, the superiority of the impact test can be demonstrated in the test room where the impact test is carried out continuously and in a large number of metallurgy and mechanical manufacturing plants that perform the impact test.
Digital pendulum impact testing machine for metal is equipped with LCD digital display controller, dual control dual display function. The liquid crystal digital display controller adopts PLC control and measurement, and performs calculation according to the reverse lift angle of the pendulum after the test sample is punched. The anti-lift angle β value and the absorbed power of the pendulum to the sample are automatically displayed. , And impact toughness ak value, add a small print can also print test data, the average power of the three tests, and test time and serial number and other content.
The main body of digital pendulum impact testing machine for metal adopts cast steel material, which makes it rigid in the whole test process, has strong impact resistance, is not easy to be deformed, has accurate test results and has a long service life. The use of high-torque clutches and high-power motors makes it more stable and vibration-free when the pendulum is placed and placed.
Digital charpy pendulum impact testing machine is developed and produced in accordance with the national standard GB/T 3808-2002 "Inspection of the pendulum impact tester". According to the national standard GB/T 229-2007 "The Charpy Pendulum Test Method for Metallic Materials", the impact test on metallic materials is carried out. Meet JJG 145-2007 "pendulum impact tester verification procedures." If you change the structure and replace the relevant parts, you can meet the requirements of the American Standard, European Standard ASTM E23, EN 10045, ISO 148, ISO 83 and other international relevant standards.
