300J LOW TEMPERATURE AUTOMATIC FEEDING C-TYPE FULLY ENCLOSED PENDULUM IMPACT TESTING MACHINE

Specifications

300JCOMPUTER CONTROLLED AUTOMATIC PENDULUM IMPACT TESTING MACHINE

Brief introduction:

   the machine can be used for the determination of anti-impact performance of metal materials when it is under dynamic loading, thus judged the quality of materials under dynamic loading. It is applicable for the laboratory, which does continuous compact tests, metallurgy, machinery manufacturing, and other industries.

Main features

It adopts computer control, electric swing, impact, computer measurement, calculation, screen digital display and printing, etc., with high work efficiency and high test accuracy. after impacting the sample, the residual energy can be used to swing automatically to prepare for the next test. the operation is simple and the work efficiency is high. In the continuous impact test laboratory and a large number of impact test metallurgy, machinery manufacturing and other industries, its advantages can be more reflected. The computer can calculate and display the impact absorbed energy, impact toughness, pendulum angle and average value of the test, and print the data.

the main machine is supported by double supports. the main shaft is supported by simply supported beam, and the radial load distribution of bearing is reasonable. In particular, a large number of impact machines can reduce the deformation of main shaft and greatly reduce the energy loss caused by bearing friction.

It adopts two-stage standard reducer to lift hammer and runs smoothly.

the hanging and swinging device adopts hydraulic buffer, and the hanging and swinging is stable.

the three-dimensional design of the pendulum ensures the accuracy of the strike center and the pendulum torque.

the impact knife is fixed with screws, which is easy to replace.

after the sample is broken, it can be judged automatically and output.

the main machine is equipped with safety pin and safety net.

the impact test of metal material is carried out according to national standard GB/T 3808-2020 " Pendulum Impact Testing Machine", GB/T 229-2007 " Metal Charpy Pendulum Impact Testing Method", international standard ISO R148 "Simply Supported Beam (V-notch) Impact Test of Steel" and ISO R83 "Charpy Impact Test of Steel (U-notch).
