Air cylinder pushing type device for cutting carbon fiber prepreg and method

Abstract

The invention discloses an air cylinder pushing type device for cutting carbon fiber prepreg and a method. The device comprises a component mounting plate, air cylinder guiding rail connecting pieces,air cylinders, cutting knives and a cutting board; a plurality of bosses in different lengths are arranged on the component mounting plate; the air cylinder guiding rail connecting pieces are arranged on all the bosses; the distance between each air cylinder guiding rail connecting piece and the adjacent air cylinder guiding rail connecting piece in the length direction of the corresponding bossis L, and L is the width of the prepreg required to be cut; the air cylinders are arranged on the air cylinder guiding rail connecting pieces; tool components capable of moving are arranged on pistonsof the air cylinders; the cutting knives are arranged on the tool components; and the cutting board is arranged at the lower end of the component mounting plate. According to the device and the method, the cutting width of the prepreg is adjustable, the cutting module can be extended, the prepreg cutting width and the narrow prepreg cutting number can be controlled, the cutting efficiency is improved, and the flexibility of the device is increased.

Description

technical field [0001] The invention belongs to the field of resin-based carbon fiber prepreg cutting and processing, and in particular relates to a cylinder-driven device and method for cutting carbon fiber prepreg. Background technique [0002] Components made of resin-based carbon fiber prepreg have the characteristics of high specific strength, high specific modulus, light weight, low density, high fatigue resistance, and high corrosion resistance. These excellent characteristics make resin-based carbon fiber reinforced composites widely used In aerospace, wind power blades, automobile industry, shipbuilding industry and sporting goods and other fields. The automatic fiber laying technology has the characteristics of high laying efficiency and high precision and has gradually replaced manual laying. The fiber winding technology can realize the manufacture of large curvature and complex special-shaped components. Generally, the width of resin-based carbon fiber prepreg p...
