Double-press roller automatic laying-and-winding shaping device used for ridged revolving body

Abstract

The invention discloses a double-press roller automatic laying-and-winding shaping device used for a ridged revolving body and relates to the technical field of automatic shaping for composite materials. The device includes a main press roller mechanism and an auxiliary press roller mechanism, both of which are provided with compression force with different air cylinders. The auxiliary press roller can swing around the axis of the main press roller. Under normal laying-and-winding situation, mainly with the main press roller, the auxiliary press roller moves along with the main press roller toassist compression of a cloth tape, a prepreg having been laid before. As the press roller arriving at a ridge of the revolving body, the auxiliary press roller can compress the prepreg cloth tape onto the ridge, and at this time, the main press roller has left from the surface of the mold of the revolving body; then, the postures of the main press roller and the revolving body are simultaneouslycontrolled, so that the prepreg cloth tape, between the main press roller and the auxiliary press roller, quickly winds the ridge on the revolving body; then the posture of the main press roller is re-controlled to press the prepreg cloth tape tightly; finally normal laying operation on the prepreg cloth tape is continuously performed. The device can greatly shorten the laying shaping time of theridge zone on the revolving body and increases the automatic laying-and-winding shaping efficiency of the whole revolving body.

Description

technical field [0001] The invention relates to the technical field of automatic laying and forming of composite materials, in particular to an automatic laying and wrapping forming device with double pressure rollers for a rotary body with ribs. Background technique [0002] As a mainstream manufacturing technology for large and complex components of high-performance composite materials, automatic composite material placement technology has become a standard manufacturing technology for large aerospace vehicles, and is widely used in the automatic lay-up and molding of large components such as aircraft fuselages and wings. [0003] At present, the automatic laying technology is also used in the molding of some composite material spars or special-shaped rotary bodies with edges and corners. The curvature of the edges and corners is relatively large, and there are many problems in the process of laying and compacting over the edges. In addition, because the edge is thin, it c...

AI Technical Summary

Problems solved by technology

In addition, because the edge is thin, it cannot bear a large compressive force

[0004] To sum up, there is a lack of laying devices suitable for materials containing edges and corners in the prior art, so as to avoid the problems of low laying efficiency and the inability to withstand high pressure when ordinary laying devices are used.
