The utility model provides a drop hammer
impact testing
machine, which comprises an experimental box body, an experimental cavity, an experimental platform, a
hydraulic cylinder, a
hydraulic cylinder, a
hydraulic cylinder, a hydraulic cylinder and a hydraulic cylinder, the drop hammer mechanism is arranged above the experiment box body, a vacuum cavity is formed in the top of the drop hammer mechanism, the drop hammer mechanism is further provided with a drop hammer channel which is arranged in the vertical direction and communicates with the vacuum cavity and the experiment cavity, and an experiment hammer body is connected into the drop hammer channel in a sealed and sliding mode; and the vacuum
control unit is connected with the vacuum cavity and is used for enabling the experimental hammer body to move upwards in the drop hammer channel after negative pressure is applied to an area above the experimental hammer body in the vacuum cavity and the drop hammer channel. The vacuum
control unit is used for providing negative pressure for the area above the vacuum cavity and the experiment hammer body, so that the experiment hammer body ascends in the drop hammer channel, and compared with a traditional mechanical lifting mode, the lifting mode is more efficient and stable, the experiment hammer body can be quickly lifted, the experiment preparation time is shortened, and the experiment efficiency is improved.
