1. Overview of JBW -300Z /500Z microcomputer controlled automatic impact testing machine
1. JBW -300Z /500Z microcomputer-controlled 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 front energy of the pendulum and the remaining energy after the impact is displayed on the dial to obtain the absorbed work of the sample. The maximum impact energy is 300J/500J, and a 150J/250J pendulum is attached. The section of the sample used is (10×10) mm. This machine has large impact energy and is suitable for ferrous metals with large impact toughness, such as steel and its alloys.
2. This machine is a fully automatic impact test, equipped with a pneumatic special sample feeding device to automatically send the sample. The pneumatic end face positioning method is used to center the sample to ensure that after the sample completes the low-temperature test, the impact time will not exceed 4 seconds. Test accuracy and work efficiency. Pendulum fetching, hanging pendulum, sample delivery, positioning and impact are all automatically controlled by electrical appliances. After breaking the sample, the remaining energy is used to automatically raise the pendulum to prepare for the next impact test. Therefore, it is better to demonstrate its superiority in the laboratory that continuously conducts low-temperature impact tests and the metallurgical and machinery manufacturing plants that do a large number of low-temperature impact tests. Sex.
3. This machine is equipped with a computer and printer, with dual control and dual display functions. The machine adopts P L C automatic control and measurement, and performs operations inverse Y pendulum angle after samples thrust measured spin compiled automatically display reverse angle β Yang and Charpy absorbed energy value of a sample done , ak value and impact toughness, and can be edited and data generated by the computer and the test report specific data processing and control software, and can also store print the test data , the average power of the three tests, and the testing time and number, etc., may also be Realize remote data transmission .
4. The impact body of this machine is made of cast steel material , which makes it rigid and stable throughout the test process, strong impact resistance, not easy to deform, accurate test results, and long service life. The use of a large torque clutch and a high-power motor makes it more stable and vibration-free when taking and placing the pendulum.
5. This machine is developed and produced in accordance with the national standard GB/T 3808-2007 "Inspection of Pendulum Impact Tester", and the impact test of metal materials is carried out in accordance with the national standard GB/T 229-2007 "Charpy Pendulum Test Method for Metallic Materials" , And comply with JJG 145-2007 "Verification Regulations for Pendulum Impact Testing Machine". If the structure is changed and the related parts are replaced, it can meet the requirements of the American and European standards ASTM E23, EN 10045, ISO 148, ISO 83 and other relevant international standards . (Special order)
6. Add a low-temperature test device, which can also be used as a microcomputer controlled low-temperature automatic impact test. Low temperature specifications: -30°, -40°, -60°, -80°, -100°, -190°.
