Example Embodiment

[0023] figure 1 As shown, a kind of ship shell rib pull-in manufacturing method comprises the following steps:

[0024] a. Cut the ribs according to the precision requirements of the ship: the allowable deviation of the outer dimensions of the ribs: for a rib with a length of 10m, the length deviation is not greater than ±2mm, and the height deviation is not greater than ±1mm; the upper and lower ends of the ribs are equipped with multiple A through hole along its length direction, the cutting accuracy tolerance of the two through holes is ±3mm; the cutting accuracy deviation d of the upper and lower sides of the cross-section of the rib is not greater than ±1.0mm (such as figure 2 , 3 , 4 shown);

[0025] b. According to the precision requirements of the ship, the longitudinal face plate and longitudinal web are cut, and then assembled to make the longitudinal: every 2m of longitudinal face plate and longitudinal web, the unevenness is ±1.0mm, the straightness is ±1.0mm ev...

Abstract

The invention relates to a pull-in manufacturing method of rib plates of a ship shell plate. The method comprises the steps that a, the rib plates are cut according to the ship precision requirement; b, a longitudinal rib panel and a longitudinal rib web plate are discharged according to the ship precision requirement; c, an FCB tailored welding inner shell plate is discharged according to the ship precision requirement, and longitudinal ribs are welded to the inner shell plate; d, the ends of the longitudinal ribs on the inner shell plate are aligned to lower penetrating holes of the rib plates and are gradually pulled into the multiple rib plates, the rib plates and the inner shell plate are welded into an inner shell component; and the rib plates are rigidly reinforced; e, according to the step a to the step d, an outer shell plate with the rib plates is also manufactured; f, hoisting equipment is utilized for lifting and pulling so as to turn the inner shell plate welded with the rib plates over, and upper penetrating holes in the rib plates of the inner shell plate and the ends of the longitudinal ribs of the outer shell plate are aligned; the longitudinal ribs of the outer shell plate are pulled into the rib plates of the inner shell plate, and the rib plates of the inner shell plate and the outer shell plate are welded to form an outer shell component; the inner shell component and the outer shell component are welded to form the complete ship shell plate.

Description

technical field [0001] The invention relates to the manufacture of ship components, in particular to a manufacturing method for pulling in ship shell ribs. Background technique [0002] At present, in the manufacturing process of straight segmented shell plates of ships, the commonly used rib installation methods are the rib insertion method and that is, the R-shaped incision with the size of the through hole of the rib is larger than the size of the longitudinal panel, and then the rib is inserted into the longitudinal Bone fragments, and finally welded repair boards. Also the assembling method needs a large amount of repair plates, the assembling is time-consuming and laborious, the efficiency is low, the assembling and welding precision is poor, and the fatigue strength of the hull structure is reduced. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a time-saving and labor-saving, high-prec...
