Introduction: JBD-300W microcomputer-controlled low-temperature automatic impact testing machine used to determine the metal material under dynamic load resistance to impact performance, in order to determine the material under dynamic load properties. The use of pendulum impact before the potential energy and the impact of the remaining potential energy difference in the dial displayed on the way to get the sample absorbed power. The maximum impact energy of 300J, and attached to a 150J pendulum, the specimen cross section (10 × 10) mm. This machine has a greater impact energy, suitable for larger impact toughness of ferrous metals, such as steel and its alloys. Features: 1. The machine is a low temperature test and impact testing machine, equipped with a special sample-feeding device automatically send samples, using end-positioning method to make the sample alignment, to ensure that the sample is completed after the low temperature test, baked to the impact of time less than 4 seconds, Improve test accuracy and work efficiency. 2. Sample cooling, thermostat, temperature adjustment, take pendulum, hanging pendulum, sample sending, positioning, impact are electric automatic control, auto-complete. After breaking the sample, the residual energy is automatically raised to prepare for the next impact test. Therefore, in the laboratories that continuously conduct low-temperature impact tests and the metallurgical and mechanical manufacturing plants that do a lot of low-temperature impact tests, it can better reflect its superiority Sex. 3. 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 value of anti-yaw angle β and the hammer automatically absorbed the work done on 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. 4. The main body of the impact of the use of cast steel, so that during the entire test rigid and stable, strong impact resistance, not easily deformed, the test results are accurate, long service life. The use of large torque clutch and high-power motor, so take swing and put the pendulum more stable without vibration. 5. Low-temperature part of the Cascade compressor refrigeration technology, the use of heat balance principle and the cycle of mixing methods to achieve automatic uniform cooling of the sample, constant temperature and temperature control.
