Embodiment Construction

[0040] In order to facilitate the understanding of those skilled in the art, the structure of the present invention will be further described in detail with reference to the accompanying drawings:

[0041] refer to Figure 1-15 , a bulbous bow manufacturing process that is separated from the left and right and then combined, including the production of the left part, the production of the right part, and the overall production of the bulbous bow. The left part and the right part are carried out with the most aft bulkhead as the reference plate Combined system to form a complete bulbous bow, the specific process is as follows:

[0042] (1) Production of the left part:

[0043] will be as figure 1 The middle vertical wall panel 1 shown is hung up as figure 2 For the positioning of the horizontal platform frame shown, the levelness of the middle longitudinal wall plate and the levelness accuracy error of the horizontal platform frame are all controlled within ±2mm;

Abstract

The invention relates to a process for manufacturing a bulbous bow in a left-right split manner then in a combined manner. The process comprises the steps of left part manufacturing, right part manufacturing and integral manufacturing of the bulbous bow, wherein a left part and a right part are manufactured in a combined manner with a partition board at the most tail end taken as a datum plate; and the integrated bulbous bow is formed; in the left part manufacturing and the right part manufacturing, original aloft operation of framework assembly, framework welding and butt welding of an outer upper plate and an outer plate is changed into normal operation, the left part and the right part are turned horizontally, and fillet welding of the outer plate and the framework is performed. Original difficult operation of the fillet welding of the outer plate and the framework in a narrow space is changed into the normal operation, so that the labor intensity of a constructor is reduced to a large extent, the efficiency is improved by more than 40% at the same time, the processing cycle is shortened, the manufacturing cost of the bulbous bow is saved, and the process has a wide market prospect.

Description

technical field [0001] The invention relates to a manufacturing process of a bulbous bow, in particular to a manufacturing process of a bulbous bow that is divided into left and right and combined. Background technique [0002] Bulbous bow, also known as bulbous bow, referred to as bulbous bow, is the bow part of the bow that is approximately spherical in shape below the design waterline. The bulbous bow is a special bow that people are very familiar with, and it has been widely used by modern transport ships. The main function of the bulbous bow is to reduce resistance and improve the speed of the ship. It has a more prominent impact on low-speed fat ships engaged in long-distance transportation. According to statistics, when the ship is fully loaded, the bulbous bow can reduce the main engine power of the ship by 10%- -20%. The bulbous bow is also conducive to the installation of the first side thruster and sonar. [0003] The bulbous bow of the ship is complex in shape...
