1、 Low temperature automatic impact testing machine Purpose:
Jbd-300w microcomputer controlled low temperature automatic impact testing machine is used to measure the impact resistance of metal materials under dynamic load, so as to judge the properties of materials under dynamic load. The difference between the potential energy before impact and the residual potential energy after impact is displayed on the dial to obtain the absorbed work of the sample. The maximum impact energy is 300j and a 150j pendulum is attached. The cross section of the sample is (10 × 10) mm. This machine has large impact energy and is suitable for ferrous metals with high impact toughness, such as steel and its alloys.  
Executive standard:
The machine is developed and produced according to the national standard GB / T 3808-2002 "inspection of pendulum impact testing machine", and the impact test of metal materials is carried out according to the national standard GB / T 229-2007 "metallic materials Charpy pendulum impact test method", and conforms to JJG 145-2007 "verification regulation of pendulum impact testing machine". If the structural form is changed and the related parts are replaced, the requirements of American Standard and European standard ASTM E23, en 10045, ISO 148, ISO 83 and other international standards can be met at the same time.
2、 Features of low temperature impact test machine:
When the sample is sent to the furnace for 4 seconds, it is equipped with an automatic impact device to ensure that the test sample is not sent to the furnace for more than 4 seconds.
Sample cooling, constant temperature, temperature regulation, swing, hanging pendulum, sample delivery, positioning, impact are all controlled by electrical automation. After punching the specimen, the residual energy is used to swing automatically to prepare for the next impact test. Therefore, its advantages can be reflected in the laboratory where low-temperature impact test is carried out continuously and metallurgy and machinery manufacturing plants which do a lot of low-temperature impact test.
This machine is equipped with a computer and a printer, with dual control and dual display function. The machine is controlled and measured by PLC automatically. According to the counter lift angle of the pendulum after punching the broken sample, it can automatically display the value of the counter lift angle β, the absorbed energy of the sample by the pendulum, and the impact toughness AK value. It can also edit the data and generate the test report through the computer and the special data processing and control software. It can also store and print the test data and the level of the three tests It can also realize remote transmission of data, time and data.
The impact body of the machine adopts Cast steel material The test results are accurate and the service life is long. The high torque clutch and high-power motor are used to make it more stable and vibration free when taking and releasing the swing.
In the low temperature part, the cascade compressor refrigeration technology is adopted, and the principle of heat balance and circulating stirring mode are used to realize the automatic uniform cooling, constant temperature and temperature regulation of the sample.
