Abstract

The invention discloses a cutting device and a cutting method for composite material prepreg. The cutting device comprises: a base; a rocker, one end of which is rotated and installed on the base; a cutting system, and the cutting system is installed on the rocker; The first steering system. The first steering system is installed on the base and connected with the rocker to adjust and display the deflection angle of the rocker relative to the base. The cutting device and cutting method of the composite material prepreg have simple structure and convenient operation, can quickly and accurately adjust the cutting knife to the required fiber angle direction, ensure the accuracy and consistency of the fiber cutting angle, and improve cutting efficiency.

Description

technical field [0001] The invention relates to the technical field of composite material forming, in particular to a cutting device and a cutting method for multi-directional laminated prepregs of composite materials. Background technique [0002] Composite materials are widely used in aviation, aerospace, high-speed rail, automobiles and other fields due to their high specific strength, high specific stiffness, fatigue resistance, and corrosion resistance. In various molding processes of composite materials, the cutting of prepreg (fiber cloth) is an indispensable link. Therefore, the application of cutting devices plays an extremely important role in the molding efficiency of composite materials. [0003] At present, the cutting of prepreg (fiber cloth) is mainly divided into two categories: one is cutting and preparing materials by the blanking machine, which is mainly used in the molding of large-size parts, such as wings, spoilers, drooping plates, etc.; It is manuall...
