Introduction: JBW series impact testing machine is used to test the impact resistance performance of metal materials under dynamic load. It is also the most commonly used impact testing machine on the market. Features: 1. The machine is controlled by PC microcomputer, electric pendulum, impact, microcomputer measurement, calculation, screen display results and printing, etc., with high work efficiency and high test accuracy. After impacting the sample, the remaining energy can be used to automatically lift the pendulum to prepare for the next test. The operation is simple and the work efficiency is high. The computer can calculate and digitally display the impact absorption energy, impact toughness, pendulum lifting angle and the average value of the test, and can print the current test data and the average value of the test 2. The main body of the testing machine is a single-support column structure, cantilever hanging pendulum, and pendulum pendulum U-shaped; 3. The impact knife is installed and fixed with screws, and the replacement is simple and convenient; 4. Sample simply supported beam support; 5. The host is equipped with safety protection pins and equipped with safety protection nets; 6. The testing machine is semi-automatic control, and the lifting pendulum, hanging pendulum, impact and release are all electrically controlled, and can use the residual energy after breaking the sample to automatically raise the pendulum to prepare for the next experiment, especially suitable for continuous impact The testing laboratory and a large number of metallurgical and mechanical manufacturing departments that do impact testing; the testing machine meets the requirements of GB/T229-2007 "Charpy Notched Impact Test Method for Metals" for impact testing of metal materials. Technical parameter: Model: JBW-300B Display mode: computer screen display Impact energy: 150/300J The distance from the center of the pendulum axis to the impact point: 750mm Impact velocity: 5.2m/s Pendulum pre-lift angle: 150° Specimen support span: 40+0.2mm Jaw fillet: R1-1.5mm Impact blade fillet: R2-2.5mm, R8±0.05mm Sample size: 10 (7.5, 5, 2.5) mm × 10 mm × 55 mm
