A device and method for positioning a slitting knife to slit multi-width prepreg

Abstract

Disclosed are a splitting cutter positioning and multi-width prepreg splitting device and a splitting cutter positioning and multi-width prepreg splitting method. The splitting cutter positioning andmulti-width prepreg splitting device comprises a splitting table, wherein a cold air pipeline is arranged on one side of the splitting table, a splitting round cutter shaft is arranged above the splitting table, the splitting round cutter shaft comprises a first shaft segment, a second shaft segment and a third shaft segment, the second shaft segment and the third shaft segment are respectively arranged at two ends of the first shaft segment, the third shaft segment comprises a shaft connected with the second shaft segment, a fixed disk is arranged on the shaft, the fixed disk comprises a central disk, a plurality of cylindrical bulges are arranged on two sides of the central disk, the cylindrical bulges are horizontally arranged, the radius of the cylindrical bulges is gradually decreasedalong with increase of the distance from the cylindrical bulges to the central disk, and a plurality of splitting round cutters are arranged on the corresponding cylindrical bulges. The splitting cutter positioning and multi-width prepreg splitting device and the splitting cutter positioning and multi-width prepreg splitting method can split prepreg at high accuracy, can simultaneously split multiple prepreg narrow bands of the equivalent or different width, improve splitting efficiency, achieve that one shaft serves several purposes, reduce the amount of resin adhered to the splitting cutters, and improve side cutting quality of the prepreg after being split.

Description

technical field [0001] The invention belongs to the field of slitting processing of resin-based carbon fiber prepregs, and in particular relates to a device and method for slitting multi-width prepregs with positioning slitting knives. Background technique [0002] Resin-based carbon fiber prepreg is an advanced composite material. The components produced by it have the characteristics of high specific strength, high specific modulus, light weight, low density, high fatigue resistance, and high corrosion resistance. At present, resin-based carbon fiber Reinforced composite materials have been widely used in the aviation industry, wind power generation blades, automobile manufacturing and other large industrial fields. Fiber automatic laying technology is the collective name of automatic wire laying forming technology and automatic tape laying forming technology. It is an advanced fully automatic fiber laying technology developed on the basis of fiber winding technology, whic...

AI Technical Summary

Problems solved by technology

Generally, the existing slitting device has limited slitting accuracy, and can simultaneously slit and cut multiple prepreg narrow strips of equal width, but in actual laying, higher precision and multi-width series of prepreg narrow strips are required
