Abstract

The invention provides a manufacturing method of a large tail casting structure of a ship. The manufacturing method includes the following steps that the large tail casting structure of the ship is transversely broken to form an upper part and a lower part, and the upper part and the lower part are cast separately; a jaw-shaped connecting frame is arranged between the upper part and the lower part; and the upper part and the lower part are welded to the jaw-shaped connecting frame to form the tail structure of the ship. By means of the manufacturing method, a large casting can be precisely machined, the manufacturing period is short, and the cost is low.

Description

technical field

[0001] The invention relates to the technical field of ship building, in particular to a method for manufacturing a large stern casting structure of a ship. Background technique

[0002] At present, the shipping market is sluggish. It is one of the most effective means to compete by reducing the operating cost of ships and improving the economic performance of ships. Optimizing the line shape of the bow and stern of the ship and reducing the resistance of the ship can reduce the power of the main engine and reduce fuel consumption at the same speed, so as to achieve the above goals. After optimizing the line shape of the bow and stern, the line shape of the ship becomes very thin in a considerable range above the stern post outlet, which directly leads to a large increase in the shape of the stern casting, usually more than 5 meters long and 4 meters wide, and some The length even reaches 6 meters and the width exceeds 5 meters. Such large castings have gre...
