A cooling and welding device for thin-walled sheet metal parts

Abstract

The invention discloses a cooling and welding device for thin-walled sheet metal parts, comprising a base, a first positioning seat, a second positioning seat, a profile positioning cooling mechanism, an angular positioning mechanism, a pressing mechanism and a welding turntable for connecting Positioning mandrel, parts to be welded are installed between the first positioning seat and the second positioning seat, the parts to be welded include thin-walled sheet metal parts and blades, and the thin-walled sheet metal parts are installed in cooperation with the top surface of the blade; the first shaft of the blade The neck end is fixedly installed on the first positioning seat, the second journal end of the blade is fixedly installed on the second positioning seat, the profile positioning cooling mechanism is pressed against the thin-walled sheet metal part, and the angular positioning mechanism is pressed against the blade body of the blade In the middle of the side, the pressing mechanism is pressed against the two ends of the blade body of the blade; the welding device can reduce the transient thermal deformation of thin-walled sheet metal parts during the welding process, so as to ensure the profile of the sheet metal parts. .

Description

technical field [0001] The invention relates to the technical field of sheet metal parts welding, in particular to a cooling and welding device for thin-walled sheet metal parts. Background technique [0002] Thin-walled sheet metal products usually refer to products with a thickness of less than 1mm. Because the thermal conductivity of thin-walled sheet metal parts is 3 times that of steel, the temperature field changes greatly, the melting area is large, and the welding seam forming is difficult to control. Therefore, when welding It is very important to conduct the heat in the welding area from the workpiece in time. If the conduction is not timely, the heat will accumulate in the welding area of ​​the workpiece, causing the temperature of the welding area to rise rapidly, and the product will have problems such as welding penetration and collapse. [0003] At the same time, when the profile requirements of thin-walled sheet metal parts are high, electron beam welding wit...
