Semi-automatic impact testing machine. Semi-automatic impact testing machine use and performance characteristics of the Company's production of JB-500B semi-automatic pendulum impact testing machine is in strict accordance with international GB / T3808-2002 "pendulum pendulum impact testing machines," the development of products, in accordance with international GB / T229-2007 "metal Charpy notched impact test method" impact testing of metallic materials. Operation using semi-automatic control, easy operation, high efficiency, the use of the residual energy of the pendulum thrust sample after Yang placed automatically. When the continuous impact test specimens, to better reflect its superiority. 2.

Semi-automatic impact testing machine operating conditions a, the temperature range of 10 ~ 35 ° C; b, relative humidity less than 85%; c, non-corrosive medium surrounding environment; d, installed in the thickness of not less than 300mm concrete foundation or fixed on the basis of more than 1400 kg; e, machine base mounting reference level of the adjusted 0.2 / 1000 or less; 4. Semi-automatic impact testing machine structure Introduction 500B pendulum impact tester consists of the following components: body, take place bodies hanging off the pendulum mechanism, automatic Yang pendulum signaling device, consisting of the dial, pendulum, protective equipment, electrical parts. Aircraft maximum impact energy 500J, 250J and with a pendulum. The sample cross-section was 10 × 10mm. Toughness mainly larger ferrous metal, especially steel and its alloys tested. The principle of the test products before and after the use of pendulum impact potential energy difference between the impact of the remaining potential energy displayed on the dial of the way to get the test specimen absorbed energy. 5.
