Problems solved by technology

The propeller blade formed after assembly has discontinuous fibers at the blade root, and the connection stability is poor
In addition, the composite material blade also adopts the co-curing molding process. When the shape of the composite material blade is irregular, there are disadvantages such as complicated preformed layering process, long manufacturing cycle and high cost, and poor product quality.

Abstract

The invention discloses a manufacturing method and product of a split-type composite propeller, comprising: 1) a propeller hub fabrication step: 1-1) a propeller hub preforming step: laying prepreg sheets according to a predetermined method to obtain a propeller hub preform shape; 1-2) the forming step of the propeller hub: put the preform of the propeller hub into the forming die of the propeller hub, heat and pressurize to obtain the propeller hub; 2) the making steps of the propeller blade: 2-1) the preforming step of the propeller blade: according to the The predetermined method covers the prepreg to obtain the blade preform; 2-2) the blade forming step: put the blade preform into the blade forming mold, heat and pressurize to obtain the blade; 3) the bonding step : Apply glue on the bonding surface of the blade and the first recessed part of the propeller hub respectively, then connect the bonding surfaces of two or more blades with the first recessed part of the propeller hub one by one and fix it, and finally after drying After roasting, the product is obtained. The invention has the characteristics of convenient manufacture, high production efficiency and good connection stability.

Description

technical field [0001] The invention relates to a manufacturing method of a propeller, in particular to a manufacturing method and product of a split-type composite propeller. Background technique [0002] A propeller is a device that relies on the blades to rotate in air or water to convert the rotational power of the engine into propulsion. There may be two or more blades connected to the propeller hub, and the rearward side of the blades is a helical surface or similar to the propeller. A type of marine propeller with a helical surface. At present, propellers include conventional metal propellers and composite propellers. Compared with conventional metal propellers, composite propellers have the advantages of light weight, high efficiency, low vibration, seawater corrosion resistance, and easy maintenance. [0003] In the prior art, the existing composite propellers are generally of a combined structure, that is, the blades and the propeller hub are prepared separately, ...
