Forming tooling and forming method of composite j-shaped floor beam blank

Abstract

The invention relates to a molding tooling and molding method of a composite material J-shaped floor beam blank. The molding device is composed of an upper die, a middle die and a lower die; the upperdie is composed of an upper left die, an upper right die, a pressing die, a middle upper die, an upper left compression bolt, an upper right compression bolt and a middle upper compression bolt; themiddle die is composed of a left middle die, a right middle die, a left middle compression bolt and a right middle compression bolt; the lower die is composed of a lower left die, a lower right die, aplatform, a left base, a right base, a lower right compression bolt and a middle lower compression bolt. The composite material J-shaped floor beam blank formed by the molding tooling has high layingefficiency, the molding steps are simple and are easy to operate, automatic production can be realized, the production efficiency is high and the product quality is stable and reliable.

Description

technical field [0001] The invention relates to a forming tool and a forming method of a composite material J-shaped floor beam blank, belonging to the technical field of composite material forming. Background technique [0002] The existing J-shaped floor beam blank forming method is to manually lay blanks layer by layer on a mould, and then assemble the mold with the blanks. The specific method is to divide the J-shaped floor beam into four parts according to the design configuration: C-shaped blank, Z-shaped blank, bottom plate and filling core material. The filling core material is prepared by special equipment or molds, and the C-shaped blank, Z-shaped blank and bottom plate are prepared by manual laying. When laying up, first prepare the laying molds of the C-shaped blank on the left, the Z-shaped blank on the right and the bottom plate, and the surfaces of the C-shaped blank on the left and the Z-shaped blank on the right are respectively C-shaped and Z-shaped.

Problems solved by technology

[0003] The deficiencies in the existing technology are: 1. Since the lay-up mold is in a right-angle shape, the prepreg in the vertical part is not easy to stick to the mold surface during lay-up, and the lay-up efficiency is low; Gas phenomenon, affecting product quality; 3. Repositioning is required when laying up mold combinations, and the accuracy is not easy to guarantee
