Machining tooling and method for curved panel

Abstract

The invention provides a machining tooling and method for a curved panel. The machining tooling for the curved panel comprises a plurality of vertical columns used for supporting the curved panel. Themultiple vertical columns are distributed at intervals in parallel. Each vertical column comprises a bottom pipe, a top pipe opposite to the upper part and the lower part of the bottom pipe and a lead screw arranged between the bottom pipe and the top pipe. The top ends of the top pipes are used for being fixedly connected with the curved panel. The two ends of each lead screw are connected withthe corresponding bottom pipe and the corresponding top pipe in a threaded mode correspondingly. The middle of each lead screw is provided with a holding part. The lead screws are rotated through theholding parts, and the distance from each bottom pipe to the corresponding top pipe is adjusted. The end faces of the top ends of the multiple vertical columns form a curved surface, and the degree ofcurve of the curved surface is consistent with the designed degree of curve of the curved panel. The degree of curve of the curved panel is corrected according to the end faces of the top ends of thevertical columns so that the curved panel can be fixed to the machining tooling. Therefore, when the curved panel is machined again, the large deformation quantity of the curved panel cannot occur, the stability of the shape of the curved panel is ensured, and segment and folding assembly of the curved panel are facilitated.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a curved panel processing tool and processing method. Background technique [0002] At present, in the field of shipbuilding and marine engineering, the connection positions where stress is easy to concentrate, such as the bow, stern and structural connections, need to adopt a streamlined design. For example, hyperbolic panels are often used at the joints between columns and deck boxes, columns and buoys of deep-water semi-submersible platforms. The material and thickness of these outer plates are often required to be very high, the material is generally above E36, and the thickness is usually between 20-35mm. The double-curved panel has a closing allowance and no weld bevel, so the workshop can not process the profile in one time, and the precision of the processed surface is not high. [0003] Opening the weld bevel by cutting allowance before assembly will further increase ...

AI Technical Summary

Problems solved by technology

The double-curved panel has a closing allowance and no weld bevel, so the workshop can not process the profile in one time, and the precision of the processed surface is not high

[0003] Cutting margin before assembly to open weld bevel will further increase the precision deformation of curved panels and hyperbolic panels, resulting in segmentation, closing, and waste of a lot of manpower and material resources in the assembly of curved panels and hyperbolic panels

In order to ensure the construction period, the traditional processing method can only be assembled in the section and closing area forcibly, and the assembler has to cooperate with the fire repairer, so a large number of assembly and fire repair workers are added, and the production efficiency is low.

Moreover, a large number of shaping processes have caused great damage to the base metal, resulting in problems such as curvature and smoothness, and toughness reduction of the steel plate.
