Device for laying composite cap-shaped stringer

Abstract

The invention discloses a device for laying a composite cap-shaped stringer, which comprises a laying head support structure provided with a prepreg tape unwinding shaft (11) and a lining paper recovery shaft (15), and a first cylindrical guide roller (1), a first drum-shaped guide roller (2), a tape pre-deformation restraining assembly (3), a cap top face compaction roller (4), a cap waist face compaction roller (5), a cap edge face compaction roller (6), a final forming compaction roller (7), a lining paper deformation restraining assembly (8), a second drum-shaped guide roller (9) and a second drum-shaped guide roller which are acting on a prepreg tape are sequentially installed on the laying head supporting structure. The device is provided with the tape pre-deformation guide roller and a guide plate, the tape can be restrained and preliminarily bent into a cap shape, and pre-deformation before prepreg tape laying is achieved; and each compaction roller has deformability, so that self-adaption of the shape and the pressure is realized, and compaction of an R angle area is guaranteed.

Description

technical field [0001] The invention relates to the field of laying hat-shaped stringers of fuselage, in particular to a device for laying hat-shaped stringers made of composite materials Background technique [0002] The composite stringer is the main supporting member of the composite fuselage structure, and is usually connected to the fuselage skin by co-handover or co-curing process. Since the hat-shaped stringer structure is the most stable, more than 90% of the fuselage stringers use the hat-shaped stringer. How to manufacture hat stringers with high quality and efficiency has become the key to the manufacture of composite fuselage structures. [0003] At present, the laying process of hat-shaped girders mainly includes manual laying process, thermal diaphragm process and automatic rolling process. The manual laying process is to cut the prepreg and manually lay it on the hat-shaped long stringer male mold. It does not require any professional automation equipment. I...

[0004] In the prior art, the patent applications whose publication numbers are CN 110962367 A and CN 110733190 A all use the rolling process. Although the automatic rolling process can continuously mass-produce long stringers with various cross-sectional shapes, because the preformed body material is still used It is difficult to guarantee the molding quality and precision of the R corner area if the sheet is turned over; in addition, the mold transfer is required to increase the molding steps
