Embodiment 1

[0021] An assembly process for ship parts, comprising the steps of:

[0022] (1) The selection of frame datum is mainly determined according to the change of hull or molded line and the improvement of construction conditions. The minimum height of the entire tire frame is generally 1.30 meters, and the minimum height shall not be less than 1.20 meters;

[0023] (2) Tangential tire frame: when the base plane of the tire frame is parallel to the base line of the ship bottom and perpendicular to the plane of the frame, it is suitable for the bottom section, deck section and side section with less linear change. The cut tire frame is relatively easy to manufacture, segmented, welded, and marked;

[0024] (3) Single bevel cut tire frame: when the side section with a small rib series in the rib line type can adopt single bevel cut (also known as positive bevel cut;

[0025] (4) Chamfered frame: For the side sections with large bow and stern curvature changes, double chamfered fram...

Abstract

The invention discloses a ship component molding bed manufacturing process. The ship component molding bed manufacturing process includes the following steps that the lowest height of a whole molding bed is generally 1.30 m and is not smaller than 1.20 m; when a datum plane of the molding bed is parallel to a ship bottom base line plane and meanwhile the datum plane is perpendicular to a rib plane, the molding bed is suitable for a bottom segment, a deck segment and a side segment with the smaller line type change, and the side segment with the lower rib level in rib line types is adopted so as to be beveled singularly; according to essentials for cutting the datum plane of the molding bed, whether a segmented rib line is horizontal or perpendicular or oblique is judged, the level of a rib is known, the molding bed is not steep longitudinally if the level change is small, the molding bed is obviously and obliquely lifted longitudinally if the level change is large, the transverse gradient of the surface of the molding bed is made to not exceed 15 degrees to 20 degrees to the greatest extent, the longitudinal gradient is made not to exceed 10 degrees, and four angles of the molding bed are as close as possible. According to the ship component molding bed manufacturing process, the molding bed is simple in operation and convenient to detach, manpower resources and time are saved, and ship assembly is facilitated.

Description

technical field [0001] The invention relates to a ship component, in particular to a manufacturing process of a ship component frame, and belongs to the technical field of ship component assembly. Background technique [0002] The evolution of the shipbuilding production management model is welding instead of riveting to build steel ships. Shipbuilding production has experienced the evolution from traditional shipbuilding to modern shipbuilding. The main driving force is the development of shipbuilding technology; It is an applied science to study the shipbuilding process and methods under the conditions of management, according to the shipbuilding concept of "integration of shell and outfitting coating"; the main task of shipbuilding technology is to establish the best ship production process system, including shipbuilding schemes, manufacturing methods and Process flow, process equipment, construction accuracy standards and testing methods, as well as maximizing the applic...
