The semi-automatic impact testing machine produced by Jinan Jinli Testing Instrument Co., Ltd. (Jinan Jinli Testing Machine Factory) has an electric pendulum swing and automatically raises the pendulum after impact. It is especially suitable for batch and continuous testing. The host design is strictly in accordance with the national standard/"Inspection of Pendulum Impact Testing Machine", and the impact test of metal materials is carried out in accordance with the national standard "Metal Charpy Notch Impact Test Method". The sample cross-section is , and it is mainly used to test ferrous metals with high impact toughness, especially steel and its alloys. This machine adopts a cantilever beam structure, which improves the rigidity of the impact machine, ensures the accuracy of test data, and greatly improves the service life of the testing machine. This machine is equipped with an axial positioning device, which has the advantages of simple operation for placing specimens, high work efficiency, high positioning accuracy, and reliable indication. Therefore, it is especially suitable for cold impact testing in conjunction with the low-temperature bath for impact testing. This machine uses a three-phase four-wire power supply.
