Anti-deformation adjustment method of hull base surface

Abstract

The invention relates to the technical field of shipbuilding, and discloses a method for adjusting the anti-deformation of the tire frame and the base surface of the hull. Numerical value and specified position, adjust the support top to drive the rotary hinge to rotate, so that the welded base panels on the left and right frames swing downward with the rotary hinge as the rotation axis, so that the left and right frames are tilted until the anti-deformation is satisfied The required value and specified position, then cut off the overlap margin, and carry out assembly and welding work. During the welding process, the shrinkage of the weld seam drives the rotary hinge to rotate in the opposite direction, and the tire frame body is pulled back to the position of the reference working base surface, and the weld seam position is flat, so that Anti-deformation adjustment is carried out before welding and assembly. The deformation caused by the internal stress caused by weld shrinkage during welding is offset by the preset anti-deformation reserved value. The entire hull base surface will not cause errors due to welding and assembly, ensuring that the ship is built. installation accuracy.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for adjusting the anti-deformation of the base surface of a ship body. Background technique [0002] In the process of ship construction, traditional fixed-pillar tire frames, horse-board template tire frames and base-surface template tire frames are generally used. These traditional fixed tire frames are not easy to adjust, and the tire frame template needs to be cut and shaped according to the lofting data when the deformation is reversed. Because the traditional template type tire frame reverse deformation depends on the line type of the template, and the template line type has been set before the template is cut. It is determined that different line types require different template data, which is time-consuming, labor-intensive, and waste of materials. For this reason, when the welded base panel is laid, its molded line is the molded line after the reverse defo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for adjusting the anti-deformation of the base surface of the hull, so as to solve the problem that the internal stress generated by shrinkage after welding and cooling leads to large deformation at the base panel of the welded base when welding on the traditional fixed tire frame, and the anti-deformation process It is difficult to control, affects the installation accuracy of the next process and requires a lot of correction work, which seriously affects the efficiency of ship construction
