TB-500 contact current collector shoe wall plate weak connection special impact testing machine

Product description The impact sample notch broaching machine is the only device that can process the notch of the qualified Charpy impact sample except for the optical curve grinder in the country. The machine adopts the processing principle of one-time forming, and the machined notch has excellent uniformity. This equipment is a necessary special equipment for metallur...

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 absorptio...

Usage and Characteristics The impact test has strict requirements on the notch of the impact specimen, and the small change of the notch will cause a large deviation of the test result. In order to ensure the gap of the impacted specimen is qualified, the inspection of the quality of the gap is an important control method. At present, optical projection magnification ins...
