A thin plate welding deformation control device

Abstract

The invention relates to a sheet welding deformation control device. A welding platform (9) is provided with a rotating hole; a rotating guiding column (11) is arranged in the rotating hole; the upper end of the rotating guiding column (11) is connected with a welding station lining plate (8); the welding station lining plate (8) is connected with a red copper base plate (7); two sets of welding clamping devices are arranged on the welding platform (9); each welding clamping device comprises a fixed arm (1); the fixed arm (1) is connected with an adjusting sleeve (1a); a horizontal adjusting arm (3) is connected in the adjusting sleeve (1a); and an air cylinder (4) and a ballast plates (6) are connected on the adjusting arm (3). The sheet welding deformation control device has the advantages that: the good heat dissipation performance of the red copper base plate is fully utilized, thus the base plate welding effect is achieved, the welding deformation can be controlled to the maximum extent, and the flatness of the welded sheet is guaranteed; and in addition, the air cylinder is used for clamping rigidly, so that the operation is very convenient, and the work efficiency is improved greatly.

Description

Technical field: [0001] The invention relates to a welding device, in particular to a thin plate welding deformation control device. Background technique: [0002] Welding deformation is one of the common problems in the welding process, especially in the welding process of aluminum alloy sheet, which is determined by the physical properties of aluminum alloy that its welding deformation is larger than that of steel plate. In the welding process of aluminum alloy sheets, due to the great difference between the thermal physical properties of aluminum and steel, such as the linear expansion coefficient of aluminum is about 2 times that of steel, but its elastic modulus is only 1 / 3 of steel, and the thermal The strength is low, and the welding deformation of aluminum structural parts is obviously larger than that of steel; in addition, the oxide film on the surface of aluminum (Al 2 o 3 ) specific gravity (3.8g / cm 3 ) greater than the specific gravity of aluminum (2.7g / cm 3...
