Metal pendulum Charpy impact test machine 300J

Product Description

The JB-300J 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.

Product Display

The JB-300B pendulum impact tester produced by our company is developed according to the international GB/T3808-2002 "Inspection of pendulum pendulum impact tester", according to international GB/T229-2007 "Metal Charpy Notched impact test method" impact test on metal materials. The operation adopts semi-automatic control, which is easy to operate and high in work efficiency. The remaining energy after the sample is broken by the pendulum can be automatically lifted. When the impact test of the sample is continuously performed, the superiority is better demonstrated.

Features

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;

Product Details

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.
