Problems solved by technology

However, in the production and use of the existing steel hydraulic cylinders, there are disadvantages of heavy weight. At the same time, the improvement of the strength of the steel structure is contradictory to the weight reduction of the cylinder body. The performance in terms of damage and other aspects is not ideal, and it will be very inconvenient in installation, maintenance, disassembly, handling, etc.
The problem of "heavy weight" of steel hydraulic cylinder greatly limits the use of the cylinder

Abstract

The invention relates to a cylinder body of a hydraulic oil cylinder with a carbon fiber reinforced composite structure. The cylinder body comprises a composite structure oil cylinder outer barrel, a piston rod, a top spiral end socket and a bottom spiral end socket. The composite structure oil cylinder outer barrel is of a cylindrical structure, a piston rod is coaxially installed in the composite structure oil cylinder outer barrel in a guiding and sliding mode, the top spiral end socket and the bottom spiral end socket are coaxially installed at the two axial ends of the composite structure oil cylinder outer barrel correspondingly, the composite structure oil cylinder outer barrel is composed of a thin-wall metal steel barrel and a carbon fiber reinforcing layer, and the carbon fiber reinforcing layer wraps the outer surface of the thin-wall metal steel barrel. According to the cylinder body of the hydraulic oil cylinder with the carbon fiber reinforced composite structure, on the basis of a traditional low-alloy steel hydraulic oil cylinder body, low-density, high-strength and high-modulus carbon fibers and low-density and high-strength aluminum alloys are used for replacing traditional low-alloy steel, a novel cylinder body process technology is applied, and the novel composite structure hydraulic oil cylinder which is lighter in mass, higher in strength, longer in service life, safer and more reliable is manufactured.

Description

Technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and is specifically a carbon fiber reinforced composite structure hydraulic cylinder cylinder. Background technique [0002] Hydraulic cylinders are a very important execution unit (part) for hydraulic devices. It is a special component for various lifting machinery, coal mine machinery, special vehicles and construction machinery. However, in the existing steel hydraulic cylinder production and use, there is a large disadvantage. At the same time, the improvement of steel structural strength is contradictory with the weight of the cylinder head, and the steel structure is anti-fatigue, corrosion, and wear resistant. The performance of the loss is not ideal, it will be inconvenient in installation, maintenance, disassembly, and handling. The problem of "weight" "weight" in the steel hydraulic cylinder is greatly limited to the use of the cylinder. First, since the oil tank is overweig...
