Problems solved by technology

For example, the Chinese patent document (201110049605.6) discloses a high-speed cutting experimental device based on the Hopkinson compression bar loading technology. This cutting device uses a small-caliber light air gun to indirectly load the tool, and its energy is limited, so it is difficult to achieve extreme cutting. High cutting speed, and the sale and use of light air guns are prohibited by the state, so this device is not suitable for general scientific research; Chinese patent document (201210031362.8) discloses a high-speed cutting experimental device based on light air gun loading technology, the device It is also the indirect loading of the tool. Although it can achieve a high cutting speed, it also has the problems of complex equipment, high safety hazards, and high experimental costs; Chinese patent literature (201110308593.4) ​​discloses an explosive high-speed cutting device. The principle is to use the strong gas pressure generated by the explosion of gunpowder to drive the tool rod to drive the blade to hit the workpiece at high speed. This device has a simple structure and low cost, but it cannot control the cutting speed, and there are certain safety hazards when using gunpowder.
