The JBW-300J charpy impact tester is used to determine the impact resistance of metal materials under dynamic loads and to determine the quality of materials under dynamic loading. It is particularly suitable for laboratories that continue to conduct impact tests as well as metallurgical and mechanical manufacturing industries that perform a large number of impact tests.

The main technical parameters

This series of impact testing machine is a high-stiffness mainframe, microcomputer control, automatic temperature control, automatic sample feeding positioning, automatic measurement and recording test machine. It is the highest level of pendulum impact testing machine in China.

The series of impact testing machines are designed and manufactured according to ISO 148:1998, GB/T 3808-2010 "Inspection of pendulum impact testing machine". Fully meet the requirements of domestic and international metal material impact test standards.

The series of impact testing machines are powerful, stable and reliable, accurate in testing and easy to operate. It is an ideal test equipment for testing the impact resistance of metal materials under dynamic load and judging the toughness and brittleness of materials.

This series of impact testing machines can test the impact resistance of metal materials at normal temperature and low temperature, as well as the ductile-brittle transition temperature of materials.

This series of impact testing machines can be widely used in research institutes, testing institutions, universities, aerospace, military, metallurgy, machinery manufacturing, pressure vessels, ships, vehicles, bridges, wind power and other industries for precision materials research, Material analysis, material development, material selection, process improvement and quality control.

The integrated design of the main frame and the base and the overall casting process overcome the weak link of the split joint of the fuselage base, and the overall rigidity and stability are greatly improved, which improves the stability of the test. The absorption energy of the body is small, and the measurement result is closer to the true absorption work of the sample. More suitable for high energy impact;

The integrated structure avoids the error of the connection and assembly of the base structure of the split structure;

The main machine adopts high rigidity design, and each force component is subjected to finite element analysis and design, and is precision processed and tested;

The machining center has a bearing hole and an anvil mounting position before and after processing, ensuring that the front and rear bearing holes are symmetrical, ensuring an accurate distance from the axis of the pendulum shaft to the striking point;

Double-supported frame structure, the pendulum main shaft is supported by simply supported beams, and the load distribution is reasonable, which reduces the lateral vibration of the pendulum during impact;

The front and rear bearings of the pendulum shaft are balanced by force, which reduces the friction and reduces the impact damage to the bearing;

Imported high-precision bearings with low friction, impact resistance and long life;

The pendulum rod is a thick-walled seamless tube with high rigidity and no deformation, which reduces energy absorption;

The three-dimensional software of the pendulum round hammer is precisely designed with precise center of gravity; the circular structure effectively reduces the air resistance energy loss during impact;

Special material for impact blade, high hardness, small deformation and impact resistance;

It is equipped with 2mm and 8mm impact blades, and the screw is pressed to fix the impact blade. The replacement is simple and convenient;

Three energy display modes: microcomputer display, dial, LCD screen (optional host embedded PLC liquid crystal display), the results can be compared with each other

The uniquely designed cold chamber and sample delivery structure can meet the specifications of 10mm, 7.5mm and 5mm. After replacing the accessories, a small sample of 2.5mm can be satisfied;

The hanging pendulum device adopts a hydraulic buffer mechanism, and the hanging pendulum is stable without shaking, thereby avoiding impact and damage to the hanging and disengaging mechanism;
The electric drive is disengaged and clean, ensuring that the initial impact energy and initial speed are not affected.
