Abstract

The invention discloses a composite material guiding and shearing integrated device which comprises a drive module, a guide shearing knife, a guide knife table and an external cutting knife. The drive module is arranged on a rack, connected with top threads of the guide shearing knife and used for driving the guide shearing knife to be in straight line motion. The guide shearing knife is arranged in a guide groove hole in the guide knife table, driven by the drive module and used for shearing composite material fiber silk strands. The guide knife table is arranged on the rack and used for guiding shearing motion of the guiding and shearing integrated device. The external cutting knife is arranged on the guide knife table and used for being matched with the guide shearing knife for utilization, and guiding and shearing the fiber silk strands. According to the composite material guiding and shearing integrated device, a silk strand guiding device and a shearing device are integrated, and action of a shearing mechanism initiatively helps the silk strands to go through the guide device, so that the reliability that silk strands are resent after being sheared is increased, the problems that silk strands are offside, deviate and are inlaid in connecting gaps in the laying process are avoided, the size of the mechanism is reduced to a largest degree, and the mass is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic laying and forming of composite materials, in particular to an integrated device for guiding and shearing of a composite material laying machine, which is mainly used for performing multi-bundle fiber tows during laying and forming of multi-bundle composite fiber tow materials. Independent cutting and guiding. Background technique [0002] Composite materials have the advantages of high specific strength, high specific modulus, fatigue resistance, good vibration damping, and good manufacturability. These advantages are of great value to the performance of aircraft, and have been widely used in the aerospace industry. At the same time, in other industries, the amount of composite materials is also increasing. [0003] Composite monolithic components with high curvature profiles, such as aircraft fuselage sections, and other elliptical heights such as jet engine cowlings, intake ducts, nozzles, c...
