A winding device for processing aircraft girder belts with composite materials

Abstract

The invention belongs to the technical field of airplane manufacturing, and relates to a winding device for processing an airplane girder tape by using a composite material. The winding device comprises a winding frame, a slide block assembly and a winding assembly, wherein the winding frame comprises a winding guide rail, a handle, a screw, a nut and a baffle plate, and is used for fixing and supporting the winding assembly and the slide block assembly; the slide block assembly slides on the winding guide rail according to the requirement of a girder tape winding layer; the winding assembly is used for ensuring the winding accuracy of a prepreg tape in the winding process. The winding device is high in winding speed, high in accuracy, convenient to operate, economical and practical, the winding and molding quality requirements of airplane girder tapes for various types of airplanes are well met, and the winding and molding quality requirements of the airplane girder tapes of any airplane can be met by replacing a core mold in the winding assembly and recombining the slide block assembly according to the requirement of every layer of cutting drawing of the girder tape. Thus, the winding device has the high generality and practicability.

Description

Technical field [0001] The invention belongs to the technical field of aircraft manufacturing, and relates to a winding device for processing aircraft girder belts with composite materials. Background technique [0002] Winding technology is the fastest growing and most effective composite material manufacturing technology in recent years. The process of winding and forming of aircraft girder belt is to wind the continuous fiber impregnated with resin glue on the winding device according to a certain rule, and then form the final shape of the girder belt after the winding device is shaped, cured and demolded. Initially, the winding device of the girder belt is a winding shuttle with a length of several meters rotating on a vertical plane around the central axis. Each layer of prepreg tape is wound into a loop. Finally, all the prepreg tapes form a total ring. According to the requirements of each layer of cutting drawings, design the required straight cutting knife and oblique c...

AI Technical Summary

Problems solved by technology

This kind of winding device has a huge structure, and the labor intensity of workers is high. Defects such as uneven stress on the prepreg tape, uneven winding thickness, and winding deviation often cause errors in molding accuracy, which reduces the pass rate of the final product and produces prepreg tape. Waste, due to the inability to continuously produce many problems in the subsequent curing process of the finished product, the current winding method is limited and does not meet the requirements of processing aircraft beam belts with composite materials for modern aircraft, which restricts the processing of aircraft beams with composite materials for modern aircraft Implementation with corresponding standard requirements
