Equipment application

this equipment is used to measure the resistance of metal materials to impact under dynamic load in order to judge the properties of the material under dynamic load. Using the difference between the potential energy before the impact of the pendulum and the remaining potential energy after the impact is displayed on the dial, to obtain the absorption work of the sample. the maximum impact energy is 300J, and also attached one pendulum of 150J, and the cross section of the sample used is (10 10) mm.

this machine is the integrated machine of low temperature test and impact test machine.

the low temperature part adopts the cascade compressor refrigeration technology, using the heat balance principle and the circulation stirring method to achieve automatic uniform cooling, constant temperature and temperature adjustment of the sample.

this machine is equipped with special sample delivery device and low temperature cooling device. Sample cooling, constant temperature, temperature adjustment, pendulum picking, pendulum hanging, sample feeding, positioning, and impact are all controlled by electrical automatic control, which is automatically completed, easy to operate, and has high working efficiency. Using the remaining energy after the sample is broken by the pendulum, the pendulum can automatic swing. In continuous impact test of the samples, it can reflect its superiority. It is mainly used in measurement and quality inspection, technical supervision departments, metallurgy and iron and steel, machinery manufacturing, pressure vessels, automobile production, universities, research institutes and other industries.
