Sheet overturning device and method

Abstract

The method relates to the field of welding fixtures, in particular to a sheet overturning device and method. The sheet overturning device provided by the invention comprises a left platform, a right platform, a platform rotation support table and a fixing component. The left platform or the right platform is used for placing sheets, the left platform and the right platform are connected through the platform rotation support table, the left platform and the right platform can both rotate around the platform rotation support table to a cooperative position so as to clamp the sheets. The fixing component is used for fixing the left platform and the right platform, which are used for clamping the sheets, so as to enable the left platform and the right platform to be able to simultaneously rotate around the platform rotation support table. The device can be used for preventing the sheets from deformation in the overturning process, guarantees the overall performance of the sheets, is exemptfrom follow-up correction work, and improves work efficiency. The sheet overturning method provided by the invention, which is based on the sheet overturning device, can be used for preventing the sheets from the deformation in the overturning process, guarantees the overall performance of the sheets, is exempt from the follow-up correction work, and improves the work efficiency.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a thin plate turning device and method. Background technique [0002] Large plates in the shipbuilding industry are generally obtained by tailor welding of multiple small plates. When using this process, it is often necessary to turn over the thin plates to weld the other side. For the turning over of large thin plates, the current common practice in shipyards is: first weld one side, and then weld some lifting lugs on the thin plate, and then turn over the thin plate with a row crane. After turning over, use a cutting machine to remove the lifting lugs and use a grinder. Sand smooth. [0003] Welding lifting lugs on a large thin plate, and then turning over with a crane, on the one hand, it is easy to cause excessive local stress on the thin plate, resulting in serious local plastic deformation of the thin plate; Lifting by the lifting device lacks rigid support for the entire...

Problems solved by technology

[0003] Welding lifting lugs on a large thin plate, and then turning over with a crane, on the one hand, it is easy to cause excessive local stress on the thin plate, resulting in serious local plastic deformation of the thin plate; Lifting by the lifting device lacks rigid support for the entire thin plate surface, which may easily lead to large elastic-plastic deformation of the thin plate as a whole

This increases the workload of subsequent corrections, which is not conducive to improving production efficiency, and also has a greater impact on the overall performance of the sheet
