Hull engine hood machining and manufacturing process

Abstract

A hull engine hood machining and manufacturing process comprises the steps of S1, selection of hood raw materials; S2, hot press molding; S3, demolding of a main body semi-finished product; S4, machining of hood reinforcing ribs; S5, elimination of welding stress; and S6, grinding and polishing to obtain a finished product of the hull engine hood. According to the process, the hood main body is made of light sheet molding compounds pressed into the plate, and the sound insulation effect of the plate body is good; meanwhile, the overall weight is reduced, and then steel reinforcing ribs are connected in a mortise and tenon joint mode; the welding stress is eliminated, and the hood strength is improved; and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of ship hatch covers, in particular to a manufacturing process for a ship engine hatch cover. Background technique [0002] Large ships are usually equipped with 1-2 engine working compartments. The engine in the engine working compartment is used as the power of the whole ship, and the noise generated is relatively large. The engine working compartment is used as an exterior shell to isolate the engine from the external environment, especially The engine compartment cover must meet the requirements of aesthetics, light weight, and strong sound insulation. However, the currently used engine compartment covers are heavy, which is not conducive to reducing the total weight of the hull, which in turn affects the sensitivity of the hull movement, and the sound insulation effect of the engine compartment cover It is not very ideal, the area close to the engine working compartment is not suitable as a rest area, w...

The engine working compartment is used as an exterior shell to isolate the engine from the external environment, especially The engine compartment cover must meet the requirements of aesthetics, light weight, and strong sound insulation. However, the currently used engine compartment covers are heavy, which is not conducive to reducing the total weight of the hull, which in turn affects the sensitivity of the hull movement, and the sound insulation effect of the engine compartment cover Not very ideal, the area close to the engine working compartment is not suitable as a rest area, which wastes space in the boat
