Composite material laying compression roller with laminating-type rubber covered roller structure

Abstract

The invention provides a composite material laying compression roller with a laminating-type rubber covered roller structure. The composite material laying compression roller is provided with a metal mandrel which comprises a cylindrical mandrel body part as well as two bearing support parts correspondingly arranged at two ends of the mandrel body part; the bearing support parts and the mandrel body part are coaxially arranged, and the outer diameters of the bearing support parts are less than the outer diameter of the mandrel body part; the outer side surface of the mandrel body part is coated with an elastic rubber layer; the outer side of the elastic rubber layer is coated with a roller surface rubber layer. The composite material laying compression roller with the laminating-type rubber covered roller structure is convenient to process and manufacture and low in production cost, has long service life and favorable maintainability, and overcomes defects of the prior art.

Description

technical field [0001] The invention belongs to the special automatic belt laying equipment technology for aviation, and relates to a composite material laying pressure roller with a film-covered rubber roller structure. Background technique [0002] Advanced composite materials have the characteristics of light weight, high strength, high modulus, fatigue resistance, corrosion resistance, designability and good manufacturability. They are especially suitable for large structures and overall structures. They are ideal aeronautical structural materials. They are used in aircraft The amount of composite materials is increasing day by day, and the scope of application extends from secondary load-bearing structures (doors, fairings, stabilizers, etc.) to main load-bearing structures (wings, fuselage, etc.). At present, composite materials have become the main structure of the new generation of aircraft airframes. Materials, composite materials are also widely used in aerospace, ...

AI Technical Summary

Problems solved by technology

[0004] However, on the current automatic tape laying machine, most of the laying pressure rollers used in the composite material laying device are imported from abroad, which are expensive, easy to damage, single procurement channels, and long delivery cycle, which seriously restricts domestic composite material automatic production. The development of the laying device industry; in addition, the existing composite material laying rollers all adopt a winding structure, the processing technology is complicated, the manufacturing cost is high, the service life is short, easy to be damaged, and the maintainability is poor
