Problems solved by technology

[0002] At present, the thickness of domestic cutting carbon fiber prepreg is a thinner carbon fiber laminate made of single-layer prepreg or multi-layer prepreg stacked. The cutting thickness generally does not exceed 6mm. or other adhesives, the existing ultrasonic cutting technology is difficult to cut, the traditional cutting method is to use milling cutter processing, but the adhesive between the layers of carbon fiber laminates will form adhesion to the milling cutter, affecting the cutting quality , the cutting efficiency is low, and it is necessary to develop cutting technology for ultra-thick carbon fiber laminates to meet the application of existing manufacturing processes. It is mainly used in aerospace, wind power, automobile and other industries, and has great application development space and prospects

[0003] The existing domestic ultrasonic cutting tool has a flat-bottom design and no cutting edge, so when cutting thicker carbon fiber laminates, the cutting tool must cut into the inside of the material to be cut from the peripheral edge of the material to be cut, and then follow the design Cutting the contour of the material increases the cutting path, which affects the cutting efficiency and the utilization rate of the material to be cut, especially when cutting the cavity inside the material to be cut, it cannot meet the cutting process requirements

During the cutting process, the cutting depth needs to be adjusted every time the cutting tool is replaced. In the traditional operation mode, experienced operators need to set the knife manually. The knife setting process is complicated and the error rate is high.

The existing cutting tool is fixed by a flange connected by bolts. This installation method will cause the blade plane of the cutting tool to be randomly unstable when it is repeatedly installed. It is necessary to check the knife to confirm the blade plane
