computer systemAutomatic impact testing machineJBW-300C/JBW-450C/JBW-600C/JBW-750C is a new product developed in strict accordance with the national standard GB/T3808-2002 "Inspection of Pendulum Impact Testing Machines", which updates and replaces the JBW-B series impact testing machines. Conduct impact testing according to the national standard GB/T229 "Charpy notch impact test method for metals". This series of impact testing machines is used to test the impact resistance performance of metal materials under dynamic loads, and is an essential testing instrument for metallurgical, mechanical manufacturing and other units. The sample cross-section of 10 × 10mm is mainly used for testing black metals with high impact toughness, especially steel and its alloys. This machine adopts double column support, which improves the rigidity of the impact machine, ensures the accuracy of the test data, and greatly improves the service life of the testing machine. The maximum impact energy of this machine is 300J. It is equipped with an axial positioning device, which has the advantages of simple sample placement operation, high work efficiency, high positioning accuracy, and reliable indication. Therefore, it is particularly suitable for cold impact testing in conjunction with low-temperature impact testing tanks.
Adopting PC microcomputer control, electric swing, impact, microcomputer measurement, calculation, screen digital display results can be printed, etc., with high work efficiency and testing accuracy. After impacting the sample, the remaining energy can be used to automatically swing and prepare for the next test. The operation is simple and the work efficiency is high. Its superiority can be better demonstrated in laboratories that conduct continuous impact tests and in industries such as metallurgy and mechanical manufacturing that conduct a large number of impact tests. Computers can calculate and display the impact absorption energy, impact toughness, pendulum swing angle, and test average value of materials, and can print the test data and average value for the current test.

computer systemAutomatic impact testing machineThe characteristics of the instrument
1. The host adopts double support, and the main shaft is supported by a simply supported beam, with a hanging pendulum and a reasonable radial load distribution, which reduces the deformation of the main shaft and greatly reduces the energy loss caused by bearing friction.
2. Adopting a two-stage standard reducer to lift the hammer, the operation is smooth.
3. The hanging device adopts hydraulic buffering, ensuring smooth hanging.
4. The three-dimensional design of the pendulum ensures accurate impact center and precise pendulum torque.
5. The impact knife is fixed with screws, which is simpler and more convenient
6. Automatic judgment and output after sample breakage
7. The host is equipped with security protection pins and a safety net.
8. The impact test of metal materials is conducted according to the national standards GB/T3808-2002 "Pendulum Impact Tester", GB/T229-2007 "Charpy Pendulum Impact Test Method for Metals", and international standards ISO R148 "Steel Simply Supported Beam (V-notch) Impact Test" and ISO R83 "Steel CharPr Impact Test (U-shaped notch).

computer systemAutomatic impact testing machineStructural characteristics and advantages:
The pendulum shaft of the simply supported beam impact machine is supported by a simply supported beam method. The pendulum shaft at the hanging part is supported by bearings at both ends, and the pendulum is hung in the middle position of the pendulum shaft. The supporting column is symmetrical in front and back, with good stability, high rigidity, simple and reliable structure, and no shaking during hanging pendulum impact.
