Problems solved by technology

[0006] Generally speaking, there are almost no domestic laying heads capable of laying multi-tows as seen in public information. Although there are many mature products abroad, most of them have complex structures, and most of the bodies they carry are gantry-type, and they are not suitable for domestic technical blockade

Abstract

The invention relates to a modularized wire pavement head for automatically paving a composite material and a method. A six-axial robot-based platform design is used for paving a composite material member. The modularized wire pavement head is mainly characterized in that the wire pavement head is based on a completely modularized design, and comprises a wire coil mounting module (C), a gasket paper collecting module (D), a tension detection module (B), a tow steering module (A), a shearing, clamping and tow-reconveying module (E), a heater (F), a compression roller and the like. The modularized wire pavement head has the capability of simultaneously paving 8 bundles of composite material presoaking yarns; each tow is independently controlled; shearing of the tows and reconveying after shearing can be independently carried out; on the basis of rapid-exchange structure design, mounting and dismantling of the wire pavement head and mounting and exchanging of the tows can be conveniently carried out; on the basis of bared yarn duct design, cleaning of the wire pavement head can be conveniently carried out; and the widths of the used composite material presoaking yarns are 3.17mm, 6.35mm and 12.7mm.

Description

[0001] technical field [0002] The invention is used in the technical field of automatic laying and forming of composite materials, and relates to a modular silk laying head and a method for automatic laying of composite materials. Background technique [0003] Composite components are widely used in the aerospace field due to their excellent performance, high specific strength, high specific modulus, fatigue resistance, and good manufacturability. The extensive use of composite materials is the development trend of aircraft. In common composite material manufacturing technologies, such as RTM technology based on liquid molding, fiber winding technology based on prepreg tape, pultrusion molding technology and automatic lay-up molding technology, among them, composite material automatic lay-up molding technology is to increase composite material It is a key technology to increase the dosage, improve the level and efficiency of manufacturing technology, ensure product quality...
