Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] see figure 1 , the cylinder-driven device for cutting carbon fiber prepregs of the present invention includes components such as a component mounting plate 1, a cylinder guide rail connector 2, a cylinder 4, a slitting knife 9, and a slitting anvil 7; wherein, see figure 2 , The assembly mounting plate 1 is provided with several bosses of different lengths. The present invention takes three bosses as an example for illustration, and the number of bosses can be determined according to specific conditions. Each boss is provided with some boss holes 13, and the boss holes 13 on each boss are set in dislocation with the boss holes 13 on the adjacent bosses, and the boss holes 13 on each boss are aligned with the corresponding ones. The distance between the boss hole 13 on the adjacent boss along the length direction of the boss is L, and the width of the...

Abstract

A device and method for cutting carbon fiber prepreg driven by a cylinder, including a component mounting plate, a cylinder guide rail connector, a cylinder, a slitting knife, and a slitting cutting board; wherein, several bosses of different lengths are arranged on the component mounting plate , each boss is provided with a cylinder guide rail connector, the distance between each cylinder guide rail connector and the adjacent cylinder guide rail connector along the length direction of the boss is L, and L is the width of the prepreg to be cut; the cylinder guide rail connection A cylinder is arranged on the part, a movable cutter assembly is arranged on the piston of the cylinder, and a cutting knife is arranged on the cutter assembly; a cutting block is arranged at the lower end of the assembly mounting plate. The invention makes the prepreg slitting width adjustable and the slitting module expandable, can control the width of the slitting prepreg and the quantity of the slitting narrow prepreg, improves the slitting efficiency, and increases the flexibility of the device .

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...
