Adjusting device for straight seam splicing welding of pre-deformation thick plate and welding method thereof

Abstract

The invention relates to an adjusting device for straight seam splicing welding of a pre-deformation thick plate and a welding method thereof and belongs to the technical field of welding and fixing devices. The adjusting device comprises a welding area, a left platform and a right platform. The welding area is in a linear long strip shape. The left platform is adjacently arranged on the left side of the welding area. The right platform is adjacently arranged on the right side of the welding area and symmetrical to the left platform. A left centering pushing plate and a left end pushing plate are arranged on the left platform. The left centering pushing plate is in a long strip shape and is parallel to the welding area. The left end pushing plate is arranged on one side of the left centering pushing plate and perpendicular to the welding area. The left end pushing plate is located between the left centering pushing plate and the welding area. An inner support is rotatably connected with the inner side of the bottom of the left platform, and an elevator is rotatably connected with the outer side of the bottom of the left platform. The adjusting device is used for straight seam slicing welding of the thick wall steel plate and has the functions of end aligning and automatic centering. Meanwhile, the pre-deformation angle is adjusted before welding, and after welding, the steel plate is changed gradually up to be in a horizontal state, so that welding deformation is eliminated.

Description

technical field [0001] The invention belongs to the technical field of welding fixtures, and in particular relates to a straight seam splicing welding adjustment device for pre-deformed thick plates and a welding method thereof. Background technique [0002] In actual production, due to the limitations of raw materials and market purchases, two steel plates need to be spliced ​​to meet the size of the final product. For thin-walled steel plates, usually after centering, the two sides of the weld are pressed by piano-key pressing plates before welding to eliminate welding deformation, but for thick-walled steel plates, due to the large deformation force during welding, the piano-key pressing plates cannot Suppress or make the structure complicated and huge, and the cost is high. [0003] Therefore, it is necessary to develop a low-cost welding fixture for thick-walled steel plates and a welding method thereof, so as to eliminate welding deformation. Contents of the inventi...
